WEBVTT 1 00:00:10.640 --> 00:00:15.560 A:middle L:90% Yes, okay, we're gonna get started here and 2 00:00:16.539 --> 00:00:21.870 A:middle L:90% as I mentioned, we're being recorded and Therese Walters 3 00:00:21.879 --> 00:00:24.390 A:middle L:90% is here and all set up and so please be 4 00:00:24.399 --> 00:00:28.739 A:middle L:90% careful of the cords as far as your movement. 5 00:00:28.750 --> 00:00:32.469 A:middle L:90% I think we've got two cameras going. The screen 6 00:00:32.469 --> 00:00:34.399 A:middle L:90% looks like it's high enough. You won't be impeding 7 00:00:34.429 --> 00:00:36.770 A:middle L:90% view, but I guess trying to stay out of 8 00:00:36.770 --> 00:00:39.460 A:middle L:90% the center of that as far as your microphone, 9 00:00:39.460 --> 00:00:41.380 A:middle L:90% we've got a senator mike that's kind of fanning out 10 00:00:41.380 --> 00:00:42.960 A:middle L:90% . So I think you'll be good with your sound 11 00:00:43.740 --> 00:00:48.719 A:middle L:90% . Um I've got a clicker working so everybody's I 12 00:00:48.719 --> 00:00:52.490 A:middle L:90% think used this before on the first presentation right forward 13 00:00:52.500 --> 00:00:54.859 A:middle L:90% backwards. There's a blackout. Don't hit it if 14 00:00:54.859 --> 00:00:57.469 A:middle L:90% you do hit it again. Um And there is 15 00:00:57.469 --> 00:00:59.890 A:middle L:90% a little pointer here if you want to make uh 16 00:00:59.899 --> 00:01:04.159 A:middle L:90% NFS point on it so that's running um everybody's power 17 00:01:04.159 --> 00:01:07.299 A:middle L:90% point is up and running so you just have to 18 00:01:07.299 --> 00:01:07.739 A:middle L:90% find it. You don't have to double click it 19 00:01:07.739 --> 00:01:11.170 A:middle L:90% and get it running again except The Sexy one wherever 20 00:01:11.170 --> 00:01:15.140 A:middle L:90% you guys say you have to do that. All 21 00:01:15.140 --> 00:01:21.319 A:middle L:90% right. Um as far as Timing, I'm going 22 00:01:21.319 --> 00:01:23.180 A:middle L:90% to start my stopwatch and I will stand at nine 23 00:01:23.180 --> 00:01:26.450 A:middle L:90% minutes. You have 10 minutes to do it. 24 00:01:26.459 --> 00:01:29.159 A:middle L:90% If you're almost done in 10 minutes, I'll be 25 00:01:29.159 --> 00:01:30.010 A:middle L:90% a lenient. Right? But we don't want you 26 00:01:30.019 --> 00:01:33.849 A:middle L:90% droning on and on into 15 minutes, that's not 27 00:01:33.849 --> 00:01:38.349 A:middle L:90% gonna happen. All of all of the mentors have 28 00:01:38.739 --> 00:01:41.390 A:middle L:90% sheets that they're gonna be taking notes on about different 29 00:01:41.390 --> 00:01:44.840 A:middle L:90% things. You guys have all done presentations multiple times 30 00:01:44.840 --> 00:01:47.560 A:middle L:90% in the past for some of you. This is 31 00:01:47.560 --> 00:01:51.090 A:middle L:90% the last final of your college career, am I 32 00:01:51.090 --> 00:01:55.469 A:middle L:90% right? So this should be the very best presentation 33 00:01:55.480 --> 00:01:57.430 A:middle L:90% of your college career. I'm looking forward to seeing 34 00:01:57.430 --> 00:02:04.290 A:middle L:90% that. No pressure, no pressure, but that's 35 00:02:04.290 --> 00:02:06.180 A:middle L:90% what we're looking forward to. Are you guys need 36 00:02:06.180 --> 00:02:07.219 A:middle L:90% to go? Yeah. All right, let me 37 00:02:07.229 --> 00:02:09.460 A:middle L:90% sit down and get my that's why the land. 38 00:02:15.639 --> 00:02:25.569 A:middle L:90% Mhm, mm hmm. Yeah, yeah, I'm 39 00:02:25.569 --> 00:02:29.250 A:middle L:90% Greg. And we're working on burgess tonight bro. 40 00:02:30.139 --> 00:02:34.830 A:middle L:90% I'm doug steve for martina. So we were working 41 00:02:34.830 --> 00:02:38.270 A:middle L:90% on a site looking at 43 50 Pleasant Valley Road 42 00:02:38.280 --> 00:02:40.599 A:middle L:90% in Fairfax County. You can see it's located up 43 00:02:40.599 --> 00:02:44.439 A:middle L:90% near D. C. In the northern part of 44 00:02:44.439 --> 00:02:47.280 A:middle L:90% Virginia. It's separated by the Loudon County and Fairfax 45 00:02:47.280 --> 00:02:51.849 A:middle L:90% County uh County line. And we focused on not 46 00:02:51.849 --> 00:02:53.460 A:middle L:90% developing in that Loudon County site to make sure that 47 00:02:53.460 --> 00:02:57.229 A:middle L:90% we didn't cross over any regulations between the counties or 48 00:02:57.229 --> 00:03:00.669 A:middle L:90% zoning ordinances. Um Down here, this is the 49 00:03:00.669 --> 00:03:04.860 A:middle L:90% com plan land use map. We focused on making 50 00:03:04.860 --> 00:03:07.639 A:middle L:90% sure that we stuck with the com plant and made 51 00:03:07.639 --> 00:03:08.750 A:middle L:90% sure that we were meeting the regulations and and things 52 00:03:08.750 --> 00:03:13.159 A:middle L:90% they focused on. The com plan the zoning ordinance 53 00:03:13.639 --> 00:03:15.830 A:middle L:90% . The site actually to be rezoned and had to 54 00:03:15.830 --> 00:03:17.830 A:middle L:90% receive a special use permit. It was zoned residential 55 00:03:17.830 --> 00:03:22.430 A:middle L:90% conservation, which in Fairfax County, they looked to 56 00:03:22.430 --> 00:03:25.099 A:middle L:90% preserve the ecology and it's roughly 5 to 10 acre 57 00:03:25.099 --> 00:03:29.389 A:middle L:90% lots. Um there's a special use permit was given 58 00:03:29.400 --> 00:03:32.280 A:middle L:90% because we're developing a church and it's a roughly 33,000 59 00:03:32.280 --> 00:03:37.060 A:middle L:90% square feet and that falls under the special use permit 60 00:03:37.069 --> 00:03:38.879 A:middle L:90% as a place of worship is also is going to 61 00:03:38.879 --> 00:03:42.449 A:middle L:90% have a nursery and a future development of a playground 62 00:03:43.840 --> 00:03:46.469 A:middle L:90% . Um We did our feasibility analysis. We used 63 00:03:46.469 --> 00:03:49.349 A:middle L:90% our wetlands delineation. Uh There are no little wetlands 64 00:03:49.349 --> 00:03:53.039 A:middle L:90% located on site. We also used our web soil 65 00:03:53.039 --> 00:03:55.189 A:middle L:90% survey. There are no protected farmland soils also located 66 00:03:55.189 --> 00:03:59.060 A:middle L:90% on site, But we do have 100 year floodplain 67 00:03:59.060 --> 00:04:00.009 A:middle L:90% on site, which we had to make sure that 68 00:04:00.009 --> 00:04:03.379 A:middle L:90% we kept undeveloped to ensure the safety of the development 69 00:04:03.379 --> 00:04:08.639 A:middle L:90% and the preservation of the ecology. Um The existing 70 00:04:08.639 --> 00:04:11.270 A:middle L:90% site conditions, we do have existing water across the 71 00:04:11.270 --> 00:04:14.310 A:middle L:90% street sewer across the street and there is a connection 72 00:04:14.310 --> 00:04:17.990 A:middle L:90% to the public storm water down at the um northeast 73 00:04:17.990 --> 00:04:21.850 A:middle L:90% corner. There we also have an environmental quality corridor 74 00:04:21.860 --> 00:04:26.410 A:middle L:90% that is to remain perpetually undisturbed. However, you 75 00:04:26.410 --> 00:04:30.480 A:middle L:90% can put passive BMPs as well as unpaved trails and 76 00:04:30.480 --> 00:04:33.060 A:middle L:90% stuff through the pc. We also have a resource 77 00:04:33.060 --> 00:04:38.129 A:middle L:90% protection area which in this location is to preserve its 78 00:04:38.129 --> 00:04:42.279 A:middle L:90% in the Okay Kwan um reservoir watershed so as to 79 00:04:42.279 --> 00:04:47.519 A:middle L:90% preserve the water quality and storm water runoff. So 80 00:04:47.529 --> 00:04:51.329 A:middle L:90% we start with our grading. Um We had to 81 00:04:51.329 --> 00:04:53.920 A:middle L:90% focus on the parking lot as that was going to 82 00:04:53.920 --> 00:04:55.800 A:middle L:90% be our biggest part of the development. The site 83 00:04:55.800 --> 00:04:58.300 A:middle L:90% is located on a ridge. So we focused on 84 00:04:58.300 --> 00:05:01.259 A:middle L:90% placing the parking lot in the areas of low slopes 85 00:05:01.269 --> 00:05:03.589 A:middle L:90% to ensure that it would be less earthwork, as 86 00:05:03.589 --> 00:05:08.870 A:middle L:90% well as focusing on using that that ridge to maintain 87 00:05:08.870 --> 00:05:12.879 A:middle L:90% our runoff for storm water and to ensure that we 88 00:05:12.879 --> 00:05:14.839 A:middle L:90% were going to minimize the cost for earthquake. Since 89 00:05:14.839 --> 00:05:16.740 A:middle L:90% that is roughly one third of our coast. The 90 00:05:16.750 --> 00:05:20.550 A:middle L:90% building plot was set at 268 ft. We figured 91 00:05:20.550 --> 00:05:25.420 A:middle L:90% that 268 ft for our building elevation would best meet 92 00:05:25.430 --> 00:05:29.060 A:middle L:90% our storm water runoff and grading plan to minimize cost 93 00:05:29.060 --> 00:05:31.779 A:middle L:90% for the parking lot. Um we also have our 94 00:05:31.790 --> 00:05:34.680 A:middle L:90% step off one ft for the 1st 10 ft to 95 00:05:34.680 --> 00:05:36.759 A:middle L:90% ensure that no water is going to be running towards 96 00:05:36.759 --> 00:05:40.490 A:middle L:90% the building. R. A. D. A 97 00:05:40.490 --> 00:05:44.459 A:middle L:90% . Access is located right here and it goes to 98 00:05:44.459 --> 00:05:46.120 A:middle L:90% the west entrance of the building. It is met 99 00:05:46.120 --> 00:05:48.629 A:middle L:90% all A. D. A. Requirements and regulations 100 00:05:48.629 --> 00:05:54.680 A:middle L:90% as an introvert foot. And it consists of 6 101 00:05:55.339 --> 00:05:57.509 A:middle L:90% 80 accessible parking spots, as well as one van 102 00:05:57.509 --> 00:06:00.279 A:middle L:90% accessible parking spot. And we're using a retention pond 103 00:06:00.279 --> 00:06:03.889 A:middle L:90% site for storm water. And just moving that up 104 00:06:03.889 --> 00:06:06.220 A:middle L:90% to, we had, we initially had it lower 105 00:06:06.220 --> 00:06:09.750 A:middle L:90% than that. Once we moved it up to 264 106 00:06:09.750 --> 00:06:13.110 A:middle L:90% , we actually reduced our grading costs$500,000. So 107 00:06:13.120 --> 00:06:15.160 A:middle L:90% it was pretty interesting to see how such a small 108 00:06:15.160 --> 00:06:19.040 A:middle L:90% thing can save your cost. Mhm. All right 109 00:06:19.050 --> 00:06:20.230 A:middle L:90% , so I'm here to talk to you about the 110 00:06:20.230 --> 00:06:24.870 A:middle L:90% way utilities on site as Greg was talking about, 111 00:06:24.879 --> 00:06:27.000 A:middle L:90% there was a water main connection through a two inch 112 00:06:27.089 --> 00:06:30.160 A:middle L:90% fabricated right across the blue blue spring road That was 113 00:06:30.160 --> 00:06:33.720 A:middle L:90% connected and run with a six duct on iron pipe 114 00:06:33.720 --> 00:06:35.839 A:middle L:90% all the way to the building. One of the 115 00:06:35.839 --> 00:06:40.329 A:middle L:90% fire code regulations is that a fire hydrant be within 116 00:06:40.329 --> 00:06:42.000 A:middle L:90% 50 ft of the building. So we place that 117 00:06:42.000 --> 00:06:46.250 A:middle L:90% right across our egress access or egress access way And 118 00:06:46.250 --> 00:06:49.230 A:middle L:90% that consisted of the fire hydrant itself and a six 119 00:06:49.240 --> 00:06:51.850 A:middle L:90% valve right before we got to the building. As 120 00:06:51.850 --> 00:06:55.009 A:middle L:90% you can see, there's a three inch valve and 121 00:06:55.009 --> 00:06:57.850 A:middle L:90% at 1.5 inch water meter before the water is actually 122 00:06:57.860 --> 00:07:00.730 A:middle L:90% fed into the building. Now another fire regulation was 123 00:07:00.730 --> 00:07:02.420 A:middle L:90% that you need a fire line also going in a 124 00:07:02.420 --> 00:07:04.629 A:middle L:90% separate way. So we have that coming off right 125 00:07:04.629 --> 00:07:06.060 A:middle L:90% there. As you can see from the picture. 126 00:07:06.740 --> 00:07:12.339 A:middle L:90% The connection was actually made at 250 253 ft in 127 00:07:12.339 --> 00:07:15.939 A:middle L:90% elevation At that point and made the connection with the 128 00:07:15.949 --> 00:07:19.660 A:middle L:90% building at 259. Now the other way utility is 129 00:07:19.660 --> 00:07:23.209 A:middle L:90% sanitary sewer. This was a little more complicated than 130 00:07:23.209 --> 00:07:26.339 A:middle L:90% the simple lateral line that was connected with water. 131 00:07:26.339 --> 00:07:29.160 A:middle L:90% It was an eight PVC And as you can see 132 00:07:29.160 --> 00:07:31.240 A:middle L:90% , we connected at 252. This manhole that connected 133 00:07:31.240 --> 00:07:34.220 A:middle L:90% in with city water or the city sewage. And 134 00:07:34.220 --> 00:07:36.889 A:middle L:90% we had the case that with a 24 in corrugated 135 00:07:36.889 --> 00:07:41.199 A:middle L:90% metal pipe and that was in order to to to 136 00:07:41.199 --> 00:07:45.490 A:middle L:90% provide structural stability as across the um right away right 137 00:07:45.490 --> 00:07:47.800 A:middle L:90% here with the increased pressure of the road and vehicles 138 00:07:47.810 --> 00:07:51.290 A:middle L:90% or particular traffic. Once we got out, there 139 00:07:51.290 --> 00:07:55.120 A:middle L:90% was a clean out placed every 50 ft as per 140 00:07:55.120 --> 00:07:59.990 A:middle L:90% regulation, it crossed the storm water stormwater pipe right 141 00:07:59.990 --> 00:08:01.970 A:middle L:90% here and all clearances of code, all clearances and 142 00:08:01.970 --> 00:08:05.550 A:middle L:90% covers were to code and it ties into the building 143 00:08:05.550 --> 00:08:07.800 A:middle L:90% right in the very back. Um and as I 144 00:08:07.800 --> 00:08:11.459 A:middle L:90% said again, these are clean outs, not manholes 145 00:08:11.459 --> 00:08:15.040 A:middle L:90% every 50 ft that had, we weren't allowed to 146 00:08:15.040 --> 00:08:16.829 A:middle L:90% put one in the access way. So uh the 147 00:08:16.839 --> 00:08:20.439 A:middle L:90% 50 ft regulation I was talking about was just for 148 00:08:20.439 --> 00:08:24.519 A:middle L:90% the first, the first kind of stretch of the 149 00:08:24.529 --> 00:08:26.990 A:middle L:90% pipe. Next, I'm gonna talk to you about 150 00:08:26.990 --> 00:08:28.899 A:middle L:90% the storm water management system we put in place, 151 00:08:28.899 --> 00:08:31.379 A:middle L:90% which comprised of two main two main pipelines, one 152 00:08:31.379 --> 00:08:35.419 A:middle L:90% running both running from west to east, one on 153 00:08:35.419 --> 00:08:37.340 A:middle L:90% the northern border of the site. The other on 154 00:08:37.340 --> 00:08:43.950 A:middle L:90% the southern border consisted of 15 reinforced concrete pipes, 155 00:08:43.960 --> 00:08:46.639 A:middle L:90% inlets, grates on the two greats located here on 156 00:08:46.639 --> 00:08:50.950 A:middle L:90% the ground for the two islands and a retention pond 157 00:08:50.960 --> 00:08:54.960 A:middle L:90% that Greg was talking to you about to be. 158 00:08:56.639 --> 00:08:58.419 A:middle L:90% And as you can see the two outlets empty into 159 00:08:58.419 --> 00:09:01.960 A:middle L:90% the retention pond, an elevation of 254 ft. 160 00:09:03.529 --> 00:09:05.379 A:middle L:90% And as because it is a retention pond, we 161 00:09:05.379 --> 00:09:09.230 A:middle L:90% wanted to keep A few feet of water in there 162 00:09:09.230 --> 00:09:11.450 A:middle L:90% at all times. So the outlet structure of the 163 00:09:11.450 --> 00:09:13.580 A:middle L:90% drainage structure right here, which leads to the 36 164 00:09:13.590 --> 00:09:16.259 A:middle L:90% reinforced concrete pipe that leads to the sewer or to 165 00:09:16.259 --> 00:09:20.629 A:middle L:90% the cities Storm Water Management System is located 254 ft 166 00:09:20.629 --> 00:09:22.539 A:middle L:90% above elevation, so that's going to keep a little 167 00:09:22.539 --> 00:09:24.970 A:middle L:90% bit of water and there for us. Other than 168 00:09:24.970 --> 00:09:28.190 A:middle L:90% that, you can see it's not the most complex 169 00:09:28.190 --> 00:09:31.529 A:middle L:90% system, but it provides the means to keep the 170 00:09:31.539 --> 00:09:35.409 A:middle L:90% peak discharge of our site adequate with the pre development 171 00:09:35.419 --> 00:09:41.259 A:middle L:90% number. So it was it was a success um 172 00:09:41.269 --> 00:09:46.210 A:middle L:90% for erosion and sediment control. We deployed basic methods 173 00:09:46.210 --> 00:09:50.759 A:middle L:90% including temporary stones and entrance silk fence diversion dykes, 174 00:09:50.139 --> 00:09:54.259 A:middle L:90% sediment basin, as well as a retention pond um 175 00:09:56.240 --> 00:09:58.940 A:middle L:90% for the flow path, as you can see right 176 00:09:58.940 --> 00:10:01.940 A:middle L:90% here directs this way, and we have constructed a 177 00:10:01.940 --> 00:10:03.019 A:middle L:90% diversion dyke right here, which is called a right 178 00:10:03.019 --> 00:10:07.269 A:middle L:90% of way diversion dyke composed mainly of soil, but 179 00:10:07.269 --> 00:10:09.759 A:middle L:90% where it crosses our construction entrance right here, it's 180 00:10:09.759 --> 00:10:11.570 A:middle L:90% going to be made of stone and we're going to 181 00:10:11.570 --> 00:10:13.779 A:middle L:90% have an entrance right here. That's also going to 182 00:10:13.789 --> 00:10:16.279 A:middle L:90% be made of stone for easier crossing. As you 183 00:10:16.279 --> 00:10:18.100 A:middle L:90% can see, we have a diversion dyke down here 184 00:10:18.100 --> 00:10:20.919 A:middle L:90% to the south. Both are intended to route water 185 00:10:20.919 --> 00:10:24.860 A:middle L:90% over here to our sediment basement sediment basin was chosen 186 00:10:24.870 --> 00:10:30.269 A:middle L:90% over sediment trap because of the increased area over here 187 00:10:30.279 --> 00:10:31.549 A:middle L:90% , this is a large construction area and the sediment 188 00:10:31.559 --> 00:10:33.519 A:middle L:90% basin would be able to handle more water than a 189 00:10:33.519 --> 00:10:39.509 A:middle L:90% sediment trap would um Some of the methods used for 190 00:10:39.519 --> 00:10:43.759 A:middle L:90% the erosion smith sediment control phase two for inlet structures 191 00:10:45.639 --> 00:10:48.330 A:middle L:90% we have right here, we're going to be our 192 00:10:48.340 --> 00:10:50.129 A:middle L:90% drop for our curb inlets structures were going to be 193 00:10:50.129 --> 00:10:54.000 A:middle L:90% using wire mesh and stone and then for our yard 194 00:10:54.000 --> 00:10:56.519 A:middle L:90% drain inlets. We're going to be using a fabric 195 00:10:56.519 --> 00:11:01.240 A:middle L:90% drop. Um Over here, you can see, 196 00:11:01.240 --> 00:11:03.700 A:middle L:90% we've converted to our retention pond, which has outlet 197 00:11:03.700 --> 00:11:07.679 A:middle L:90% structure protection, which is composed of rib rep, 198 00:11:07.690 --> 00:11:09.570 A:middle L:90% which will help reduce the velocity of the water going 199 00:11:09.570 --> 00:11:13.690 A:middle L:90% into the pond. Um We have standard seating right 200 00:11:13.690 --> 00:11:16.870 A:middle L:90% here and that will also be right here in between 201 00:11:16.870 --> 00:11:18.330 A:middle L:90% the building and the parking lot, as well as 202 00:11:18.330 --> 00:11:22.120 A:middle L:90% the parking lot and the diversion dyke. Um for 203 00:11:22.120 --> 00:11:24.870 A:middle L:90% the cost estimate, we estimated it to be about 204 00:11:24.870 --> 00:11:30.470 A:middle L:90% $1.8 million. Mhm. We uh we also came 205 00:11:30.470 --> 00:11:33.409 A:middle L:90% up with some cost productions earthwork. We realized we 206 00:11:33.409 --> 00:11:35.669 A:middle L:90% could reduce it$100,000. We could do this simply 207 00:11:35.669 --> 00:11:39.429 A:middle L:90% by reducing the earthwork by one ft by half a 208 00:11:39.429 --> 00:11:43.500 A:middle L:90% foot. We came up with the second method, 209 00:11:43.500 --> 00:11:45.909 A:middle L:90% which would be removal of the islands, which would 210 00:11:45.909 --> 00:11:50.059 A:middle L:90% save about$10,000. Um We believe that this is 211 00:11:50.070 --> 00:11:54.450 A:middle L:90% uh an aesthetically pleasing and optimized plan and that concludes 212 00:11:54.450 --> 00:12:09.889 A:middle L:90% our presentation question. Okay. And take it easy 213 00:12:09.889 --> 00:12:13.240 A:middle L:90% on the layout of the parking field. Yes. 214 00:12:13.250 --> 00:12:20.240 A:middle L:90% What's going on in the middle? Is that the 215 00:12:20.240 --> 00:12:24.350 A:middle L:90% islands? Uh They wanted to focus a lot on 216 00:12:24.350 --> 00:12:26.409 A:middle L:90% storm water quality and reduce runoff. So we decided 217 00:12:26.409 --> 00:12:31.139 A:middle L:90% to put vegetated islands to provide an aesthetically pleasing area 218 00:12:31.149 --> 00:12:35.190 A:middle L:90% as well as reduce some of the impervious area within 219 00:12:35.190 --> 00:12:48.759 A:middle L:90% the parking lot. Thank you guys, Hola. 220 00:12:50.740 --> 00:12:52.960 A:middle L:90% We're rolling out. There were no. All right 221 00:12:52.960 --> 00:12:56.750 A:middle L:90% . Let's make sure. Alright, we're good and 222 00:12:56.440 --> 00:13:01.370 A:middle L:90% see. All right. Fantastic. All right. 223 00:13:01.370 --> 00:13:01.789 A:middle L:90% Thank you for being here. All the mentors for 224 00:13:01.789 --> 00:13:05.850 A:middle L:90% being here. I'm bobby. I'm Alex Teresa and 225 00:13:05.850 --> 00:13:09.519 A:middle L:90% our mentors are Caleb first and Dave parker over there 226 00:13:09.519 --> 00:13:11.789 A:middle L:90% . If you guys could wave your hands. Thank 227 00:13:11.789 --> 00:13:16.919 A:middle L:90% you very much. All right. So I just 228 00:13:16.919 --> 00:13:20.029 A:middle L:90% want to talk about a little bit of site overview 229 00:13:20.029 --> 00:13:22.730 A:middle L:90% right now. Uh so we're located in Chesapeake Virginia 230 00:13:22.740 --> 00:13:26.120 A:middle L:90% and site soils are pretty poor. Also, the 231 00:13:26.120 --> 00:13:28.879 A:middle L:90% site slopes are less than two on most of the 232 00:13:28.879 --> 00:13:33.389 A:middle L:90% site. Uh the address is located right off of 233 00:13:33.399 --> 00:13:37.549 A:middle L:90% George Washington Highway. And uh and the site acreage 234 00:13:37.559 --> 00:13:39.529 A:middle L:90% is about 17 acres. There were no wetlands on 235 00:13:39.529 --> 00:13:43.029 A:middle L:90% site and we're not 100 year flood zone. So 236 00:13:43.029 --> 00:13:45.419 A:middle L:90% we didn't really have to worry about any uh, 237 00:13:45.429 --> 00:13:48.570 A:middle L:90% anything along those lines. Also, no trees or 238 00:13:48.570 --> 00:13:50.909 A:middle L:90% brush on sites are clear. Right, okay. 239 00:13:50.919 --> 00:13:54.440 A:middle L:90% So site sketch of this. This is what the 240 00:13:54.440 --> 00:13:56.509 A:middle L:90% site could possibly look like. As you can see 241 00:13:56.509 --> 00:13:58.110 A:middle L:90% . There's a lot of men in these on site 242 00:13:58.120 --> 00:14:01.039 A:middle L:90% . Uh There's an access road from George Washington highway 243 00:14:01.049 --> 00:14:05.120 A:middle L:90% into a loop in parking structure on site. As 244 00:14:05.120 --> 00:14:07.259 A:middle L:90% you can see, there's a gym, community center 245 00:14:07.269 --> 00:14:11.529 A:middle L:90% , pool, uh community garden playground, uh basketball 246 00:14:11.529 --> 00:14:13.929 A:middle L:90% courts, tennis courts, skate park, and even 247 00:14:13.929 --> 00:14:16.100 A:middle L:90% in a Tv course on site. So there's a 248 00:14:16.110 --> 00:14:18.029 A:middle L:90% lot of features also around the site. There's a 249 00:14:18.039 --> 00:14:20.840 A:middle L:90% , there's a walking trail and this is about a 250 00:14:20.840 --> 00:14:24.139 A:middle L:90% half mile on site, and then it goes into 251 00:14:24.139 --> 00:14:26.860 A:middle L:90% another half mile trail on the south of the site 252 00:14:26.870 --> 00:14:28.720 A:middle L:90% that's already developed. So here's the center of the 253 00:14:28.720 --> 00:14:31.029 A:middle L:90% site. There's also a pavilion which can be used 254 00:14:31.029 --> 00:14:33.590 A:middle L:90% for many activities, such as bands coming in and 255 00:14:33.590 --> 00:14:37.019 A:middle L:90% maybe just a good place to hang out. So 256 00:14:37.019 --> 00:14:39.490 A:middle L:90% on to the east of sight, as you can 257 00:14:39.490 --> 00:14:41.179 A:middle L:90% see, there's a skate park, basketball courts, 258 00:14:41.179 --> 00:14:43.190 A:middle L:90% and tennis courts. And I'd like to point out 259 00:14:43.190 --> 00:14:46.450 A:middle L:90% the sanitary sewer pump station, which, which we 260 00:14:46.450 --> 00:14:48.450 A:middle L:90% have to put in because of how flat the site 261 00:14:48.450 --> 00:14:50.789 A:middle L:90% was. The reason why we chose this location is 262 00:14:50.789 --> 00:14:54.549 A:middle L:90% to minimize uh minimize the appearance. Uh You know 263 00:14:54.940 --> 00:15:01.279 A:middle L:90% , I guess uh really really not not show the 264 00:15:01.279 --> 00:15:05.059 A:middle L:90% location to the users of the site. Also to 265 00:15:05.059 --> 00:15:07.299 A:middle L:90% north, there's an access point from the walking trail 266 00:15:07.299 --> 00:15:11.639 A:middle L:90% to the northern uh the Northern community and then on 267 00:15:11.639 --> 00:15:13.429 A:middle L:90% the on the west of the site, as you 268 00:15:13.429 --> 00:15:16.210 A:middle L:90% can see community gardens, playground. Really just fun 269 00:15:16.210 --> 00:15:20.350 A:middle L:90% for the whole family. Mhm. So also want 270 00:15:20.350 --> 00:15:26.240 A:middle L:90% to talk about uh some of the requirements from Uh 271 00:15:26.250 --> 00:15:28.490 A:middle L:90% from the city of Chesapeake. They wanted a sustainable 272 00:15:28.490 --> 00:15:33.360 A:middle L:90% stormwater design where possible. And also bmp ponds should 273 00:15:33.360 --> 00:15:35.580 A:middle L:90% take up 12 of the area. Uh As mentioned 274 00:15:35.580 --> 00:15:39.669 A:middle L:90% before, there's great walk ability in circulation on site 275 00:15:39.929 --> 00:15:41.960 A:middle L:90% , and and it's really just a nice side design 276 00:15:43.740 --> 00:15:46.090 A:middle L:90% . Okay. Uh well, the site is owned 277 00:15:46.100 --> 00:15:50.450 A:middle L:90% a one for agriculture and conservation. Uh there's some 278 00:15:50.460 --> 00:15:56.100 A:middle L:90% regulations that go with that. There are parking regulations 279 00:15:56.100 --> 00:15:58.250 A:middle L:90% as far as number of parking spaces for both the 280 00:15:58.259 --> 00:16:02.169 A:middle L:90% indoor and outdoor facilities, as well as uh 88 281 00:16:02.179 --> 00:16:06.789 A:middle L:90% regulations. There's also a minimum Lot frontage of 120 282 00:16:06.789 --> 00:16:08.690 A:middle L:90% ft, a minimum width of 150 ft in a 283 00:16:08.700 --> 00:16:12.669 A:middle L:90% minimum area of an acre. And uh the site 284 00:16:12.669 --> 00:16:17.639 A:middle L:90% covered all those criteria. We also placed 30 ft 285 00:16:17.639 --> 00:16:22.639 A:middle L:90% setbacks Bob For each building, and uh less than 286 00:16:22.639 --> 00:16:29.259 A:middle L:90% 35 of the site is covered by structures. Uh 287 00:16:29.269 --> 00:16:33.009 A:middle L:90% So there are some of the water and sewer connections 288 00:16:33.009 --> 00:16:36.759 A:middle L:90% to the east side of the site. Um See 289 00:16:37.240 --> 00:16:41.570 A:middle L:90% so uh Of the 16.8 acres of land, 5.5 290 00:16:41.570 --> 00:16:48.429 A:middle L:90% of those acres are green area, and 11.3 acres 291 00:16:48.440 --> 00:16:51.610 A:middle L:90% are developed in some way, whether it's the roadway 292 00:16:51.620 --> 00:16:55.639 A:middle L:90% , the facilities or the stormwater ponds. Uh The 293 00:16:55.649 --> 00:16:59.929 A:middle L:90% design speed of the parking area is 10 miles an 294 00:16:59.929 --> 00:17:02.830 A:middle L:90% hour based on traffic analysis. Uh, There are 295 00:17:02.830 --> 00:17:06.809 A:middle L:90% also stop signs placed at each of the intersections and 296 00:17:06.809 --> 00:17:08.390 A:middle L:90% all the 88 regulations were met as far as number 297 00:17:08.390 --> 00:17:11.680 A:middle L:90% of parking spaces As well as the slope of parking 298 00:17:11.680 --> 00:17:15.529 A:middle L:90% spaces being less than 2%. All right, thank 299 00:17:15.529 --> 00:17:18.230 A:middle L:90% you Teresa. So moving on to the grading plan 300 00:17:18.240 --> 00:17:22.019 A:middle L:90% , this was definitely the most challenging part of this 301 00:17:22.029 --> 00:17:22.880 A:middle L:90% . Uh, this development as it was a very 302 00:17:22.880 --> 00:17:26.279 A:middle L:90% flat site. So we had a lot of interest 303 00:17:26.289 --> 00:17:30.720 A:middle L:90% iterations and we ended up at this final grading plan 304 00:17:30.730 --> 00:17:33.400 A:middle L:90% essentially. Um, our goal with this was to 305 00:17:33.400 --> 00:17:36.029 A:middle L:90% minimize the amount of cut because we knew that if 306 00:17:36.029 --> 00:17:37.049 A:middle L:90% we didn't do it right, we could have gone 307 00:17:37.059 --> 00:17:40.049 A:middle L:90% overboard with the amount of cut that we would have 308 00:17:40.059 --> 00:17:41.880 A:middle L:90% just to drain the site. So we haven't broken 309 00:17:41.880 --> 00:17:44.980 A:middle L:90% up into four quadrants. You can see for the 310 00:17:44.990 --> 00:17:45.960 A:middle L:90% , uh for the square part of the site. 311 00:17:45.960 --> 00:17:49.039 A:middle L:90% Right here we have four. These blue circles here 312 00:17:49.039 --> 00:17:52.750 A:middle L:90% are low points, not these aren't just the only 313 00:17:52.750 --> 00:17:53.960 A:middle L:90% inlets but these are the main. And let's um 314 00:17:55.039 --> 00:17:56.829 A:middle L:90% the red lines depict high lines across the site. 315 00:17:56.839 --> 00:18:00.569 A:middle L:90% So you can think of water flowing perpendicular to all 316 00:18:00.569 --> 00:18:03.650 A:middle L:90% of those lines. Yeah. Um And in this 317 00:18:03.650 --> 00:18:06.279 A:middle L:90% way we were able to segment it up where we 318 00:18:06.279 --> 00:18:08.569 A:middle L:90% didn't have to have water flowing across the entire site 319 00:18:08.579 --> 00:18:11.049 A:middle L:90% to be to be picked up by in let's um 320 00:18:11.049 --> 00:18:12.569 A:middle L:90% And as you can see, we were successful in 321 00:18:12.569 --> 00:18:17.430 A:middle L:90% reducing our net difference to about 2700 cubic yards of 322 00:18:17.440 --> 00:18:18.750 A:middle L:90% cut. And all of that cut will be used 323 00:18:18.759 --> 00:18:21.220 A:middle L:90% in the A. T. V. Course, 324 00:18:21.230 --> 00:18:22.480 A:middle L:90% which will be graded by an A. T. 325 00:18:22.480 --> 00:18:26.089 A:middle L:90% V. Specialist, I would assume. All right 326 00:18:26.099 --> 00:18:27.829 A:middle L:90% , moving on to stormwater management. Um As far 327 00:18:27.839 --> 00:18:30.670 A:middle L:90% as the in let's go, we had normal kurban 328 00:18:30.670 --> 00:18:33.509 A:middle L:90% , let's drop in let's and filtering and let's which 329 00:18:33.519 --> 00:18:37.940 A:middle L:90% were used to fulfill some of the sustainable stormwater um 330 00:18:37.950 --> 00:18:41.750 A:middle L:90% policies that the city Chesapeake wanted. Yeah, on 331 00:18:41.750 --> 00:18:44.500 A:middle L:90% the right here, you can see just a general 332 00:18:44.509 --> 00:18:45.869 A:middle L:90% layout for these inlets in order to make sure all 333 00:18:45.869 --> 00:18:48.440 A:middle L:90% the water gets treated before it goes into the storm 334 00:18:48.440 --> 00:18:52.339 A:middle L:90% system. Additionally, as mentioned before, we have 335 00:18:52.339 --> 00:18:55.970 A:middle L:90% got three ponds smaller. They're more aesthetically pleasing that 336 00:18:55.970 --> 00:18:57.160 A:middle L:90% way. We wanted to break up our stormwater management 337 00:18:57.170 --> 00:19:00.460 A:middle L:90% facilities on site. Additionally, we have grass whales 338 00:19:00.460 --> 00:19:03.920 A:middle L:90% in the center of the site where filtering units were 339 00:19:03.920 --> 00:19:07.210 A:middle L:90% not an option in order to maintain some level of 340 00:19:07.210 --> 00:19:10.829 A:middle L:90% treatment of stormwater as well as groundwater infiltration. As 341 00:19:10.829 --> 00:19:11.890 A:middle L:90% far as the calculation goes, technically, we use 342 00:19:11.890 --> 00:19:15.799 A:middle L:90% the rational method to determine our runoff values. Um 343 00:19:15.809 --> 00:19:19.109 A:middle L:90% and hydrographic overlays of our pre and post development hydro 344 00:19:19.109 --> 00:19:22.720 A:middle L:90% graphs to determine the minimum volumes for all of the 345 00:19:22.730 --> 00:19:26.589 A:middle L:90% for all of the ponds. Um As far as 346 00:19:26.589 --> 00:19:29.500 A:middle L:90% utility crossings goes, it could have been kind of 347 00:19:29.500 --> 00:19:30.269 A:middle L:90% a mess. We were able to minimize our crossings 348 00:19:30.269 --> 00:19:34.000 A:middle L:90% to one sanitary sewer and water line crossing and one 349 00:19:34.000 --> 00:19:37.299 A:middle L:90% water line and storm water crossing. You can see 350 00:19:37.309 --> 00:19:41.869 A:middle L:90% the crossing locations here. The storm water pipe goes 351 00:19:41.869 --> 00:19:45.329 A:middle L:90% right about up and down through here. Um And 352 00:19:45.339 --> 00:19:48.299 A:middle L:90% we were able to maintain all of the depth of 353 00:19:48.309 --> 00:19:52.109 A:middle L:90% the amount of uh leeway between you on the cover 354 00:19:52.109 --> 00:19:55.160 A:middle L:90% between the pipes. Thank you Alex. All right 355 00:19:55.160 --> 00:19:59.500 A:middle L:90% , moving on, sanitary Stewart. Uh Our sanitary 356 00:19:59.500 --> 00:20:02.269 A:middle L:90% sewer pipes were size that eight inches and made of 357 00:20:02.279 --> 00:20:06.960 A:middle L:90% PVC. Uh The pipe layout is pretty linear to 358 00:20:06.970 --> 00:20:11.839 A:middle L:90% minimize minimize costs. Uh There was one section required 359 00:20:11.849 --> 00:20:17.049 A:middle L:90% for force main that's just because of site slopes And 360 00:20:17.059 --> 00:20:18.690 A:middle L:90% to meet the minimum velocity of two ft per second 361 00:20:18.700 --> 00:20:22.059 A:middle L:90% . We applied a.39 slope on all pipes. 362 00:20:22.240 --> 00:20:26.609 A:middle L:90% Peak flow was determined to be 185 gallons per minute 363 00:20:26.619 --> 00:20:30.839 A:middle L:90% . And this was determined based on fiction accounts of 364 00:20:30.849 --> 00:20:33.190 A:middle L:90% the community centre, gym and swimming pool. The 365 00:20:33.200 --> 00:20:38.029 A:middle L:90% PQ should be approximately 200 people. Yeah. So 366 00:20:38.029 --> 00:20:41.269 A:middle L:90% improving onto water, water lines and fire protection. 367 00:20:41.640 --> 00:20:45.730 A:middle L:90% Most of of The system was comprised of 10 cast 368 00:20:45.730 --> 00:20:49.720 A:middle L:90% iron pipe, With the exception of six cast iron 369 00:20:49.720 --> 00:20:52.759 A:middle L:90% pipe for fire hydrants. Again, the services, 370 00:20:52.759 --> 00:20:57.220 A:middle L:90% the pool, community center and a gym. So 371 00:20:57.230 --> 00:21:00.640 A:middle L:90% the total fire flow demand was determined to be 1300 372 00:21:00.640 --> 00:21:03.359 A:middle L:90% gallons per minute. And uh and the city of 373 00:21:03.359 --> 00:21:07.210 A:middle L:90% Chesapeake requires 1000 gallons per minute. So we were 374 00:21:07.220 --> 00:21:12.200 A:middle L:90% far beyond that requirement. Okay, okay, well 375 00:21:12.200 --> 00:21:15.000 A:middle L:90% , for the phase one of erosion sediment control of 376 00:21:15.009 --> 00:21:18.769 A:middle L:90% , we uh deals mainly with earthworks, so we 377 00:21:18.769 --> 00:21:21.759 A:middle L:90% have to stockpiles on site. This is the organic 378 00:21:21.759 --> 00:21:25.150 A:middle L:90% stockpile and the inorganic stockpiles here to the north of 379 00:21:25.150 --> 00:21:27.069 A:middle L:90% the site. Uh We place the organic stockpiles of 380 00:21:27.069 --> 00:21:30.549 A:middle L:90% the west because a lot of that organic soil is 381 00:21:30.549 --> 00:21:33.569 A:middle L:90% going to be used for the playground and the community 382 00:21:33.569 --> 00:21:36.460 A:middle L:90% garden, which are to the west of the site 383 00:21:36.539 --> 00:21:38.700 A:middle L:90% and then the inorganic soil. The extra soil will 384 00:21:38.700 --> 00:21:41.009 A:middle L:90% be used for the A. T. V. 385 00:21:41.009 --> 00:21:44.869 A:middle L:90% Course so that soil is placed there to uh not 386 00:21:44.869 --> 00:21:47.269 A:middle L:90% have to move it quite as much. The run 387 00:21:47.269 --> 00:21:49.809 A:middle L:90% off of the site goes from northwest to southeast. 388 00:21:49.819 --> 00:21:55.789 A:middle L:90% So we place these diversion dishes here uh to pull 389 00:21:55.789 --> 00:21:57.460 A:middle L:90% the water towards the sediment trap which we have here 390 00:21:57.460 --> 00:22:00.660 A:middle L:90% in the sediment basin which is right down here. 391 00:22:03.240 --> 00:22:06.990 A:middle L:90% The second phase of erosion sediment control deals a lot 392 00:22:06.990 --> 00:22:10.230 A:middle L:90% with the storm water. So here is our storm 393 00:22:10.230 --> 00:22:11.369 A:middle L:90% water pipe network at each of these inlets. We 394 00:22:11.369 --> 00:22:17.190 A:middle L:90% place inlet protection and uh we also have some temporary 395 00:22:17.190 --> 00:22:19.750 A:middle L:90% and permanent seating which are sustainable measures in which the 396 00:22:19.759 --> 00:22:23.059 A:middle L:90% city of Chesapeake wanted. So we have some temporary 397 00:22:23.059 --> 00:22:26.200 A:middle L:90% seating here to the north, into the east and 398 00:22:26.200 --> 00:22:29.250 A:middle L:90% then to the south. There's permanent seating. The 399 00:22:29.250 --> 00:22:44.380 A:middle L:90% total cost of the project is$3.5 million Skate Park 400 00:22:44.390 --> 00:22:48.069 A:middle L:90% , the tennis courts, basketball courts in the playground 401 00:22:48.079 --> 00:22:51.130 A:middle L:90% , the swimming pool and the two buildings are separate 402 00:22:51.130 --> 00:22:52.809 A:middle L:90% from the project, so they were not priced in 403 00:22:52.809 --> 00:22:56.779 A:middle L:90% the estimate. Thank you very much. Thanks. 404 00:22:56.789 --> 00:23:06.150 A:middle L:90% Any questions questions we have. Do we have any 405 00:23:06.150 --> 00:23:12.759 A:middle L:90% questions we covered absolutely everything I'm going to pick on 406 00:23:12.769 --> 00:23:17.769 A:middle L:90% David. You can't play with that interesting. Okay 407 00:23:18.339 --> 00:23:21.599 A:middle L:90% . Okay. Alright. That's that's I don't know 408 00:23:23.839 --> 00:23:26.640 A:middle L:90% the initial scope of the project was so as far 409 00:23:26.640 --> 00:23:30.240 A:middle L:90% as what the city has been wanted, what your 410 00:23:30.250 --> 00:23:34.970 A:middle L:90% what your requirements are requirements were to provide the gym 411 00:23:34.980 --> 00:23:38.880 A:middle L:90% , community center, um swimming pool, tennis courts 412 00:23:38.880 --> 00:23:45.740 A:middle L:90% , basketball courts and uh the Hey Park we added 413 00:23:45.740 --> 00:23:45.859 A:middle L:90% in the A. T. V. Course. 414 00:23:45.869 --> 00:23:48.589 A:middle L:90% That was that was kind of a conditional thing. 415 00:23:48.599 --> 00:23:49.960 A:middle L:90% The community garden, we thought of that as we 416 00:23:49.960 --> 00:23:52.460 A:middle L:90% were going along when we realized we were going to 417 00:23:52.460 --> 00:23:56.059 A:middle L:90% have a lot of excess excess organic soil. The 418 00:23:56.069 --> 00:24:00.319 A:middle L:90% playground was also required um And because that weren't required 419 00:24:00.329 --> 00:24:03.480 A:middle L:90% were the community garden and pavilions. Yeah. Tv 420 00:24:03.480 --> 00:24:07.130 A:middle L:90% course. Right. That was yeah, that was 421 00:24:07.130 --> 00:24:10.960 A:middle L:90% just based upon the space that we had. So 422 00:24:10.970 --> 00:24:11.940 A:middle L:90% we we tried to make best use of those as 423 00:24:11.940 --> 00:24:15.670 A:middle L:90% we could when we were going through. All right 424 00:24:17.740 --> 00:24:18.519 A:middle L:90% . We actually have yes, we do. We 425 00:24:18.519 --> 00:24:19.799 A:middle L:90% do have one more slide here, Dave, would 426 00:24:19.799 --> 00:24:26.359 A:middle L:90% you stand up, please? Uh huh. Um 427 00:24:26.740 --> 00:24:27.559 A:middle L:90% So last night we went out to dinner, we 428 00:24:27.559 --> 00:24:30.730 A:middle L:90% had a great conversation, we met these guys families 429 00:24:30.740 --> 00:24:33.319 A:middle L:90% , their wives, um and we were talking about 430 00:24:33.319 --> 00:24:34.970 A:middle L:90% cars a little bit. Dave was telling me about 431 00:24:34.970 --> 00:24:38.170 A:middle L:90% how he had the opportunity recently to drive a Lamborghini 432 00:24:38.180 --> 00:24:41.890 A:middle L:90% around the track down to Disney World, which is 433 00:24:41.890 --> 00:24:42.750 A:middle L:90% one of my dream car. So he's talking about 434 00:24:42.750 --> 00:24:45.220 A:middle L:90% how he's taking this around corners. It's got some 435 00:24:45.220 --> 00:24:47.609 A:middle L:90% s turns in the middle of the track and I'm 436 00:24:47.609 --> 00:24:48.569 A:middle L:90% thinking, Man, this guy must still be in 437 00:24:48.569 --> 00:24:52.549 A:middle L:90% his mid-20s, it's actually his birthday today. So 438 00:24:52.549 --> 00:24:53.390 A:middle L:90% can we all please give a round of applause to 439 00:24:53.400 --> 00:25:02.960 A:middle L:90% Dave. Happy 29th birthday. Thank you very much 440 00:25:03.440 --> 00:25:06.109 A:middle L:90% . It's correct. I'm sure you're gonna get one 441 00:25:06.109 --> 00:25:11.359 A:middle L:90% of those suits, Yeah, Yeah, Yeah. 442 00:25:14.240 --> 00:25:15.390 A:middle L:90% All right. Hi, my name's Maya Sheehab from 443 00:25:15.400 --> 00:25:19.420 A:middle L:90% Jordan. Excellent. And we were tasked with placing 444 00:25:19.420 --> 00:25:23.180 A:middle L:90% a retail warehouse site on a, on a located 445 00:25:23.180 --> 00:25:26.279 A:middle L:90% in danville Virginia. We worked with Dewberry with brian 446 00:25:26.279 --> 00:25:30.269 A:middle L:90% Bradner and marked Albert. So this is just the 447 00:25:30.269 --> 00:25:33.160 A:middle L:90% general overview. That's gonna kind of help you guys 448 00:25:33.160 --> 00:25:34.869 A:middle L:90% understand how we came up with our final design for 449 00:25:34.869 --> 00:25:40.970 A:middle L:90% the project. Our goal was to place a 136,000 450 00:25:40.970 --> 00:25:45.250 A:middle L:90% square foot retail warehouse onto a uh, 19.12 acre 451 00:25:45.250 --> 00:25:48.190 A:middle L:90% site. We wanted to make it aesthetically pleasing, 452 00:25:48.190 --> 00:25:51.640 A:middle L:90% as well as flowing with the traffic that comes off 453 00:25:51.640 --> 00:25:53.519 A:middle L:90% of a major highway located around it. Uh, 454 00:25:53.519 --> 00:25:57.140 A:middle L:90% and we also needed to follow ordinances, zoning ordinances 455 00:25:57.140 --> 00:26:00.519 A:middle L:90% , comprehensive plan, as well as specific things that 456 00:26:00.519 --> 00:26:03.170 A:middle L:90% the owner required from us. So it's located in 457 00:26:03.170 --> 00:26:07.619 A:middle L:90% danville Virginia. It's a corner lot that is bordered 458 00:26:07.619 --> 00:26:11.369 A:middle L:90% by a highway type road Bodman boulevard, but it's 459 00:26:11.369 --> 00:26:15.880 A:middle L:90% also bordered by Bradner drive um and a row of 460 00:26:15.880 --> 00:26:19.259 A:middle L:90% houses called along Wolfpack Avenue. It's an undeveloped site 461 00:26:19.259 --> 00:26:22.509 A:middle L:90% currently, so we don't see any um harm or 462 00:26:22.519 --> 00:26:26.539 A:middle L:90% we don't have any potential demolitions that we perceive. 463 00:26:26.549 --> 00:26:30.259 A:middle L:90% But the issue on the site is that there are 464 00:26:30.259 --> 00:26:33.180 A:middle L:90% extreme slopes that range from very flat, considered to 465 00:26:33.190 --> 00:26:36.440 A:middle L:90% be 0 to 2% all the way to extremely steep 466 00:26:36.450 --> 00:26:41.599 A:middle L:90% for greater than 15%. It's located in the HRC 467 00:26:41.599 --> 00:26:44.549 A:middle L:90% district, also known as the highway retail commercial district 468 00:26:44.940 --> 00:26:48.069 A:middle L:90% . The purpose of this is to provide businesses and 469 00:26:48.069 --> 00:26:51.839 A:middle L:90% commercials with land that they can use. However, 470 00:26:51.839 --> 00:26:56.069 A:middle L:90% it is trying to limit strict development. It's it's 471 00:26:56.079 --> 00:27:00.940 A:middle L:90% meant for businesses with a less than 60,000 square foot 472 00:27:00.950 --> 00:27:04.450 A:middle L:90% uh floor area, floor area. However, as 473 00:27:04.450 --> 00:27:07.049 A:middle L:90% I said, this is 100 and 36,000 square foot 474 00:27:07.059 --> 00:27:10.640 A:middle L:90% building. So we will require a special use permit 475 00:27:10.640 --> 00:27:11.920 A:middle L:90% , which we did look up and it says that 476 00:27:11.930 --> 00:27:18.599 A:middle L:90% um single use or single retails are allowed to have 477 00:27:18.609 --> 00:27:19.980 A:middle L:90% greater than as long as we do get this special 478 00:27:19.990 --> 00:27:26.400 A:middle L:90% use permit on the existing conditions. There is One 479 00:27:26.400 --> 00:27:30.740 A:middle L:90% access point from Barman Boulevard, which is about 36 480 00:27:30.740 --> 00:27:33.109 A:middle L:90% ft wide. Um The utilities are that are present 481 00:27:33.119 --> 00:27:36.869 A:middle L:90% are located on the east and west side of the 482 00:27:36.869 --> 00:27:38.940 A:middle L:90% site. Um shown here, there's a 12 inch 483 00:27:38.940 --> 00:27:42.240 A:middle L:90% water line, um an eight inch sewer line and 484 00:27:42.250 --> 00:27:45.029 A:middle L:90% natural gas line that we will connect to know. 485 00:27:45.029 --> 00:27:48.690 A:middle L:90% Environmental issues are located on site. Um There's no 486 00:27:48.700 --> 00:27:53.740 A:middle L:90% bodies of water or wetlands. Um These are two 487 00:27:53.740 --> 00:27:56.670 A:middle L:90% conceptual layouts Lay out. one. The goal was 488 00:27:56.670 --> 00:28:00.019 A:middle L:90% to provide an aesthetically pleasing design. This was done 489 00:28:00.019 --> 00:28:03.400 A:middle L:90% by putting the front of the building facing the main 490 00:28:03.400 --> 00:28:04.799 A:middle L:90% road. Also, the building will be placed on 491 00:28:04.799 --> 00:28:07.480 A:middle L:90% a local high point. However, this will require 492 00:28:07.480 --> 00:28:11.089 A:middle L:90% a lot of grading so the goal was to, 493 00:28:11.099 --> 00:28:14.980 A:middle L:90% was to provide um design that would limit the grading 494 00:28:14.980 --> 00:28:18.269 A:middle L:90% requirements by having the building on the existing high point 495 00:28:18.640 --> 00:28:22.259 A:middle L:90% . Um Unfortunately that would make the back of the 496 00:28:22.269 --> 00:28:25.500 A:middle L:90% building face the main road, which isn't desirable for 497 00:28:25.509 --> 00:28:29.660 A:middle L:90% businesses. The final lap we went with that one 498 00:28:29.670 --> 00:28:33.589 A:middle L:90% because of the aesthetically pleasing design. Um there's a 499 00:28:33.589 --> 00:28:37.319 A:middle L:90% lot of room for the trucks to get to the 500 00:28:37.329 --> 00:28:40.869 A:middle L:90% docking site, which is right there. There's two 501 00:28:40.869 --> 00:28:44.450 A:middle L:90% access points into the parking lot for the cars. 502 00:28:45.140 --> 00:28:48.799 A:middle L:90% There's also ample amounts of parking. There's 553 general 503 00:28:48.799 --> 00:28:52.710 A:middle L:90% spots, 14 handicap spots and 10 part prowse which 504 00:28:52.720 --> 00:28:57.279 A:middle L:90% met all requirements. So the grading and for the 505 00:28:57.279 --> 00:29:00.250 A:middle L:90% site, The building was placed on a local high 506 00:29:00.250 --> 00:29:04.990 A:middle L:90% point at 534 ft high. However, the overall 507 00:29:06.000 --> 00:29:08.009 A:middle L:90% high point remain towards the north part of the site 508 00:29:08.019 --> 00:29:11.140 A:middle L:90% . This was because grading. This section would be 509 00:29:11.150 --> 00:29:15.019 A:middle L:90% too much money. So we left that like On 510 00:29:15.029 --> 00:29:19.140 A:middle L:90% the great how it was 88 spots were granted to 511 00:29:19.150 --> 00:29:23.420 A:middle L:90% two in any direction. Other spots were graded to 512 00:29:23.420 --> 00:29:27.089 A:middle L:90% a maximum of 5%. Any direction like Brazilian requirements 513 00:29:27.240 --> 00:29:33.019 A:middle L:90% specified. Um the green space, It was great 514 00:29:33.019 --> 00:29:36.420 A:middle L:90% 3-1 slope or less where it couldn't be met. 515 00:29:36.430 --> 00:29:38.380 A:middle L:90% We had to replace to retaining walls shown here. 516 00:29:38.430 --> 00:29:41.799 A:middle L:90% These are towards the bottom of the site or towards 517 00:29:41.799 --> 00:29:44.319 A:middle L:90% the south end of the site and the West East 518 00:29:44.329 --> 00:29:48.359 A:middle L:90% End of the site. Um and then The entrance 519 00:29:48.359 --> 00:29:49.740 A:middle L:90% road was greater than 10 slope, which was the 520 00:29:49.740 --> 00:29:52.539 A:middle L:90% maximum. But that was just because we had, 521 00:29:52.549 --> 00:29:56.160 A:middle L:90% we had to ensure that we connected to the elevation 522 00:29:56.160 --> 00:29:59.359 A:middle L:90% points at bombing boulevard and our slope was a little 523 00:29:59.359 --> 00:30:03.640 A:middle L:90% higher than we needed it to be. That is 524 00:30:03.240 --> 00:30:11.109 A:middle L:90% 10% slope. Hey detention crime was placed in the 525 00:30:11.109 --> 00:30:14.339 A:middle L:90% southern corner of the site unless we're used to convey 526 00:30:14.339 --> 00:30:17.890 A:middle L:90% the storm water into the essential pond and storm water 527 00:30:18.339 --> 00:30:19.710 A:middle L:90% . Storm water inlets were placed in the areas throughout 528 00:30:19.710 --> 00:30:22.609 A:middle L:90% the site where the water appears to be collecting at 529 00:30:22.609 --> 00:30:26.099 A:middle L:90% a certain location. Total of 11 11, unless 530 00:30:26.099 --> 00:30:30.589 A:middle L:90% were placed on our side and the red lines show 531 00:30:30.589 --> 00:30:36.440 A:middle L:90% the drainage area of each endless. Using the T 532 00:30:36.440 --> 00:30:37.650 A:middle L:90% . R. 55 methods, it was determined that 533 00:30:37.650 --> 00:30:44.170 A:middle L:90% are Our pond side will have to be 24,605 cubic 534 00:30:44.170 --> 00:30:48.880 A:middle L:90% feet. This was calculated using the hydrographic shown in 535 00:30:48.880 --> 00:30:53.130 A:middle L:90% the presentation. The dark blue line indicates the water 536 00:30:53.130 --> 00:30:56.950 A:middle L:90% pipe system used in the project using the drainage area 537 00:30:56.960 --> 00:31:00.000 A:middle L:90% for each and let we were able to calculate the 538 00:31:00.009 --> 00:31:04.069 A:middle L:90% flow per area and we used rational methods to calculate 539 00:31:04.069 --> 00:31:07.910 A:middle L:90% the pipe diameters. It was calculated, calculated that 540 00:31:07.910 --> 00:31:15.130 A:middle L:90% the pipe Diameters would range from 12 to 30 the 541 00:31:15.130 --> 00:31:18.819 A:middle L:90% center. The center sewer lines are the green lines 542 00:31:18.829 --> 00:31:22.970 A:middle L:90% indicated here. The water pipes. I mean the 543 00:31:22.980 --> 00:31:26.500 A:middle L:90% water pipes are the blue lines. The water pipes 544 00:31:26.500 --> 00:31:29.579 A:middle L:90% were the sizing of the water pipes were done through 545 00:31:29.579 --> 00:31:33.500 A:middle L:90% the information given from the building plans and and it 546 00:31:33.500 --> 00:31:37.450 A:middle L:90% came out to be and there were two location of 547 00:31:37.450 --> 00:31:42.589 A:middle L:90% the water entry and The domestic water entry required four 548 00:31:42.589 --> 00:31:48.470 A:middle L:90% pipe diameters and fire lines required tenants diameter. The 549 00:31:48.470 --> 00:31:51.589 A:middle L:90% fire flow requirement for the building was given to be 550 00:31:51.599 --> 00:31:53.759 A:middle L:90% 2000 gallons per minute. Using this information in the 551 00:31:53.759 --> 00:32:00.049 A:middle L:90% Virginia statewide Virginia statewide fire prevention code. The minimum 552 00:32:00.640 --> 00:32:02.640 A:middle L:90% The minimum amount of fire hydrants needed was to, 553 00:32:02.650 --> 00:32:07.759 A:middle L:90% with a maximum spacing of 450 ft. We've provided 554 00:32:07.769 --> 00:32:12.859 A:middle L:90% 35 hygiene surrounding the building. The two water lines 555 00:32:13.539 --> 00:32:16.759 A:middle L:90% where Set up parallel to each other and we're set 556 00:32:16.769 --> 00:32:21.230 A:middle L:90% five ft apart from each other and we're connected at 557 00:32:21.240 --> 00:32:23.509 A:middle L:90% the, at the vault right there, setting, 558 00:32:23.519 --> 00:32:27.970 A:middle L:90% setting the, Setting the lines together close to each 559 00:32:27.970 --> 00:32:30.480 A:middle L:90% other. Made us only dig up one ditch and 560 00:32:30.490 --> 00:32:36.809 A:middle L:90% connect and installing. Built at the same time where 561 00:32:36.809 --> 00:32:38.400 A:middle L:90% the water line across the center shoreline, we make 562 00:32:38.400 --> 00:32:42.829 A:middle L:90% sure that the waterline was at least 18 inches above 563 00:32:42.829 --> 00:32:47.200 A:middle L:90% the center sewer lines. Yeah, yeah. The 564 00:32:47.200 --> 00:32:51.289 A:middle L:90% sanitary sewer line is a green light indicating the picture 565 00:32:51.299 --> 00:32:54.170 A:middle L:90% here. It was determined that the super flow for 566 00:32:54.839 --> 00:33:00.470 A:middle L:90% for 136,000 square feet building would be 40,800 gallons per 567 00:33:00.470 --> 00:33:05.609 A:middle L:90% day, Assuming full float value is doubled and came 568 00:33:05.609 --> 00:33:08.160 A:middle L:90% out to be 81,600 gallons per day. It was 569 00:33:08.160 --> 00:33:12.769 A:middle L:90% determined that to one sanitary pipe size would be needed 570 00:33:13.240 --> 00:33:15.099 A:middle L:90% . However, due according to do very standards, 571 00:33:15.109 --> 00:33:19.950 A:middle L:90% minimum standards, Sewer Piper or six and that's what 572 00:33:19.950 --> 00:33:23.569 A:middle L:90% we use for our project site. Manholes replaced the 573 00:33:23.579 --> 00:33:29.369 A:middle L:90% directional changes intersection of two sanitary sewers and When the 574 00:33:29.380 --> 00:33:32.609 A:middle L:90% pipeline succeeded 400 ft. So for phase one, 575 00:33:32.609 --> 00:33:37.339 A:middle L:90% we determined that a majority of our problems would come 576 00:33:37.339 --> 00:33:38.220 A:middle L:90% strictly from pollution. As I said, this was 577 00:33:38.220 --> 00:33:43.099 A:middle L:90% an undeveloped site. So we placed a silk fence 578 00:33:43.109 --> 00:33:44.940 A:middle L:90% around a majority of the property. However, not 579 00:33:44.950 --> 00:33:45.599 A:middle L:90% all of it. As some of it was, 580 00:33:45.599 --> 00:33:47.509 A:middle L:90% as we said, Hi Points that would not run 581 00:33:47.509 --> 00:33:52.220 A:middle L:90% off the property. We place the temporary diversion dike 582 00:33:52.230 --> 00:33:54.650 A:middle L:90% that runs from the northern most of the property to 583 00:33:54.660 --> 00:33:58.440 A:middle L:90% the sediment basin down here in order to ensure that 584 00:33:58.450 --> 00:34:00.170 A:middle L:90% anything that was more flowing over towards Bradner Drive could 585 00:34:00.170 --> 00:34:02.950 A:middle L:90% kind of be re diverted over to the sediment basin 586 00:34:04.339 --> 00:34:07.569 A:middle L:90% . We put, sorry, replace the construction entrance 587 00:34:07.569 --> 00:34:12.679 A:middle L:90% at the existing entrance onto the site. We also 588 00:34:12.690 --> 00:34:16.059 A:middle L:90% place four sediment traps along the southern portion over here 589 00:34:16.059 --> 00:34:20.670 A:middle L:90% to ensure that anything that was flowing off would be 590 00:34:21.039 --> 00:34:24.670 A:middle L:90% protected and for inland protection to ensure the existing infrastructure 591 00:34:24.670 --> 00:34:28.050 A:middle L:90% was protected as well as the sediment basin towards the 592 00:34:28.050 --> 00:34:30.920 A:middle L:90% bottom. The second phase, we placed 11 added 593 00:34:30.929 --> 00:34:35.280 A:middle L:90% inlet protection as well as keeping everything other than the 594 00:34:35.289 --> 00:34:37.699 A:middle L:90% temporary version Dyke. We also added temporary slope drain 595 00:34:37.699 --> 00:34:40.730 A:middle L:90% , coupled with the outlet protection to ensure that everything 596 00:34:40.730 --> 00:34:44.929 A:middle L:90% was flowing to the sediment base incorrectly and permanent seating 597 00:34:44.929 --> 00:34:47.699 A:middle L:90% where the site would be finished grading at that point 598 00:34:47.710 --> 00:34:51.289 A:middle L:90% is determined that the sediment basin would be dredged and 599 00:34:51.289 --> 00:34:52.750 A:middle L:90% turn into that sediment pond at the end. This 600 00:34:52.750 --> 00:34:54.780 A:middle L:90% is the final design. Just to show you guys 601 00:34:54.780 --> 00:34:58.980 A:middle L:90% that came out to be just under$9.6 million. 602 00:34:58.989 --> 00:35:00.469 A:middle L:90% Everything. We have a lot of green space landscaping 603 00:35:00.469 --> 00:35:04.480 A:middle L:90% to keep in with the HRC district codes. I 604 00:35:04.489 --> 00:35:06.659 A:middle L:90% want to quickly say a big thank you to brian 605 00:35:06.659 --> 00:35:08.000 A:middle L:90% Bradner and marked Albert for all their help on this 606 00:35:08.000 --> 00:35:19.889 A:middle L:90% presentation. Any questions? Yes. The far to 607 00:35:19.889 --> 00:35:23.099 A:middle L:90% the fire hydrants, which prepared to be pretty close 608 00:35:23.099 --> 00:35:28.190 A:middle L:90% to the building where the police setbacks away from the 609 00:35:28.199 --> 00:35:32.199 A:middle L:90% building. Pleasant hybrids. Um, we didn't find 610 00:35:32.210 --> 00:35:35.559 A:middle L:90% any, but I think we were just more going 611 00:35:35.559 --> 00:35:37.070 A:middle L:90% off the distance and we try to connect them right 612 00:35:37.079 --> 00:35:43.730 A:middle L:90% with the violence. But uh, we tried it 613 00:35:43.730 --> 00:35:45.030 A:middle L:90% , we did it based on all the ordinances that 614 00:35:45.030 --> 00:35:47.110 A:middle L:90% we found for Danville. So we didn't see anything 615 00:35:47.110 --> 00:35:57.199 A:middle L:90% about a setback marketing. I had actually a question 616 00:35:57.199 --> 00:36:00.650 A:middle L:90% on the stonework. I don't know where that was 617 00:36:00.130 --> 00:36:05.840 A:middle L:90% somewhere. But yes, you didn't mention that. 618 00:36:06.230 --> 00:36:10.199 A:middle L:90% But it was on the any thought given the house 619 00:36:10.210 --> 00:36:16.960 A:middle L:90% pond is empty more than output from the pond. 620 00:36:16.969 --> 00:36:20.469 A:middle L:90% Um I think that when we were determining it, 621 00:36:20.480 --> 00:36:22.750 A:middle L:90% it would never have reached full capacity because we made 622 00:36:22.750 --> 00:36:30.929 A:middle L:90% it so large. Um did we? I think 623 00:36:30.940 --> 00:36:32.570 A:middle L:90% we're just going to have on the pond never be 624 00:36:32.570 --> 00:36:35.699 A:middle L:90% at full flow. It's a way bigger than it 625 00:36:35.699 --> 00:36:37.460 A:middle L:90% needs to be um in the future. I guess 626 00:36:37.460 --> 00:36:40.309 A:middle L:90% you could, there is an existing storm water right 627 00:36:40.320 --> 00:36:45.429 A:middle L:90% next to it that it could be drained into towards 628 00:36:45.429 --> 00:36:47.239 A:middle L:90% the left of the pond by the access point. 629 00:36:49.130 --> 00:36:51.550 A:middle L:90% There's like right down here. There was like existing 630 00:36:51.559 --> 00:36:53.769 A:middle L:90% stormwater like infrastructure that said we could tie into, 631 00:36:53.829 --> 00:37:05.239 A:middle L:90% I believe. All right. Thank you guys. 632 00:37:06.329 --> 00:37:14.400 A:middle L:90% Yeah. Yeah. Yes. You ready? All 633 00:37:14.400 --> 00:37:15.079 A:middle L:90% right? Good morning ladies and gentlemen, I'm Alexis 634 00:37:15.079 --> 00:37:17.840 A:middle L:90% carrel bat, john Whitlock, I'm Katie gear and 635 00:37:17.840 --> 00:37:21.070 A:middle L:90% I'm dan brzezinski. And our mentor is Dennis Quinn 636 00:37:21.070 --> 00:37:23.250 A:middle L:90% . With Christopher consulting's and our developers Madison homes. 637 00:37:24.429 --> 00:37:27.949 A:middle L:90% I'm gonna start off with the location, the zoning 638 00:37:27.949 --> 00:37:30.010 A:middle L:90% ordinance and the slope. Our location is in George 639 00:37:30.019 --> 00:37:34.940 A:middle L:90% mason boulevard and Fairfax Virginia are developing. Goal was 640 00:37:34.940 --> 00:37:37.570 A:middle L:90% to have single family detached homes. Uh Our site 641 00:37:37.570 --> 00:37:42.329 A:middle L:90% is located is in Fairfax County which is zoned R 642 00:37:42.340 --> 00:37:45.320 A:middle L:90% one which allows for one house per acre. This 643 00:37:45.320 --> 00:37:47.530 A:middle L:90% is not what our developer wanted or what the com 644 00:37:47.530 --> 00:37:50.710 A:middle L:90% plant wanted. So we re zoned to P. 645 00:37:50.710 --> 00:37:52.400 A:middle L:90% D. H. A. Which allows for a 646 00:37:52.400 --> 00:38:00.000 A:middle L:90% maximum eight units per acre. Um This also had 647 00:38:00.010 --> 00:38:05.849 A:middle L:90% no setbacks and area requirements and minimum minimal sight distance 648 00:38:05.849 --> 00:38:08.510 A:middle L:90% site, 25 green space was required as well as 649 00:38:08.519 --> 00:38:12.829 A:middle L:90% a 20 tree canopy. Within the 10 years, 650 00:38:13.219 --> 00:38:15.260 A:middle L:90% Development of the site would be very easy because our 651 00:38:15.260 --> 00:38:22.420 A:middle L:90% slope is very uh non existent um and minimize grading 652 00:38:22.420 --> 00:38:30.889 A:middle L:90% is required. Our current land use right now uh 653 00:38:30.900 --> 00:38:34.480 A:middle L:90% to the west is green space into the east is 654 00:38:34.480 --> 00:38:37.360 A:middle L:90% a bus parking lot. Our conceptual design. Our 655 00:38:37.369 --> 00:38:39.840 A:middle L:90% goal was to get as many plots Um as possible 656 00:38:39.840 --> 00:38:44.170 A:middle L:90% while mating 25 green streets and having a very pedestrian 657 00:38:44.179 --> 00:38:49.849 A:middle L:90% friendly environment. Our first conceptual design had 46 lots 658 00:38:50.070 --> 00:38:53.090 A:middle L:90% and one access point on George Mason Boulevard, which 659 00:38:53.090 --> 00:38:57.349 A:middle L:90% limits the disturbance of traffic. Um We had to 660 00:38:57.349 --> 00:39:00.400 A:middle L:90% slow community speech, which makes for a very pedestrian 661 00:39:00.400 --> 00:39:02.650 A:middle L:90% friendly environment and we had limited off street parking. 662 00:39:05.420 --> 00:39:10.250 A:middle L:90% Our second conceptual design had 55 plots to access of 663 00:39:12.219 --> 00:39:16.119 A:middle L:90% two points of access, uh which deserved the traffic 664 00:39:16.130 --> 00:39:20.820 A:middle L:90% but utilized the space better. Again, we had 665 00:39:20.820 --> 00:39:23.840 A:middle L:90% slow community speeds and lots of off street parking. 666 00:39:24.320 --> 00:39:28.590 A:middle L:90% Our next slide, you're gonna see a progression of 667 00:39:28.599 --> 00:40:04.550 A:middle L:90% what we thought with our project. Yeah. As 668 00:40:04.550 --> 00:40:07.170 A:middle L:90% you can see in our progression, the conceptual design 669 00:40:07.170 --> 00:40:09.800 A:middle L:90% stage and our final decision picking. Our first conceptual 670 00:40:09.800 --> 00:40:13.440 A:middle L:90% design allowed us to have a more green community, 671 00:40:13.809 --> 00:40:17.949 A:middle L:90% a better flow within the community and less uh impact 672 00:40:17.949 --> 00:40:20.880 A:middle L:90% to current traffic. I'm gonna pass it to john 673 00:40:20.880 --> 00:40:24.340 A:middle L:90% he's gonna talk more about the roads. Okay? 674 00:40:24.349 --> 00:40:27.530 A:middle L:90% As mentioned before, there is one existing road that 675 00:40:27.530 --> 00:40:29.170 A:middle L:90% runs right through the middle of our site and that's 676 00:40:29.170 --> 00:40:34.829 A:middle L:90% George mason boulevard. The Fairfax County comprehension plan Desired 677 00:40:34.840 --> 00:40:36.980 A:middle L:90% one access point. So we honor that in our 678 00:40:36.980 --> 00:40:39.889 A:middle L:90% design. This is our site if these are one 679 00:40:39.889 --> 00:40:44.670 A:middle L:90% thing contours. So this barry is very flat and 680 00:40:44.679 --> 00:40:47.150 A:middle L:90% our proposed roadway is on the right. We have 681 00:40:47.159 --> 00:40:50.849 A:middle L:90% Harlequin court on the left, with the cold sack 682 00:40:50.860 --> 00:40:53.190 A:middle L:90% Christopher lane on the right and road street connects George 683 00:40:53.190 --> 00:40:58.579 A:middle L:90% mason boulevard at one point, um we're use private 684 00:40:58.579 --> 00:41:00.519 A:middle L:90% roads. Were designed for private roads to have a 685 00:41:00.519 --> 00:41:02.699 A:middle L:90% little more flexibility in our road design. We maintain 686 00:41:02.860 --> 00:41:06.039 A:middle L:90% standards for almost all of it, except for really 687 00:41:06.039 --> 00:41:07.920 A:middle L:90% the 50-foot cold sack, which is a little a 688 00:41:07.929 --> 00:41:09.250 A:middle L:90% little bit tight and it's a little smaller than what 689 00:41:09.460 --> 00:41:14.820 A:middle L:90% standardized Are. We calculated our duty to about 400 690 00:41:15.210 --> 00:41:17.110 A:middle L:90% , which allows for 15 mile per hour design speeds 691 00:41:17.119 --> 00:41:20.599 A:middle L:90% 28 ft right away with 12 ft lanes and two 692 00:41:20.599 --> 00:41:23.599 A:middle L:90% ft curb and gutter. This is our boat grading 693 00:41:23.610 --> 00:41:27.809 A:middle L:90% . Um this is what the existing conditions, it's 694 00:41:27.809 --> 00:41:29.619 A:middle L:90% a little crowded. But I want to show you 695 00:41:29.619 --> 00:41:30.860 A:middle L:90% that we, the main thing we did was remove 696 00:41:30.860 --> 00:41:32.769 A:middle L:90% this dry soil at the bottom of our site to 697 00:41:32.780 --> 00:41:35.860 A:middle L:90% make room for our building pad and for some green 698 00:41:35.860 --> 00:41:39.340 A:middle L:90% space. What's up close up. But on on 699 00:41:39.340 --> 00:41:42.889 A:middle L:90% the right here is our is our boat grading and 700 00:41:42.889 --> 00:41:45.460 A:middle L:90% our main focus was the building pads. And we 701 00:41:45.460 --> 00:41:47.090 A:middle L:90% held a high point along the middle of the building 702 00:41:47.090 --> 00:41:51.219 A:middle L:90% pad, about two ft above the proposed roadway to 703 00:41:51.219 --> 00:41:52.900 A:middle L:90% allow for drainage and slope from either direction, about 704 00:41:52.909 --> 00:41:55.579 A:middle L:90% 21 on this, on towards the road in about 705 00:41:55.590 --> 00:41:58.920 A:middle L:90% 10 to 1 towards the back. And that was 706 00:41:58.929 --> 00:42:00.739 A:middle L:90% really the main focus of milk, grinning and there 707 00:42:00.739 --> 00:42:04.079 A:middle L:90% wasn't too much else to it. And the detailed 708 00:42:04.079 --> 00:42:07.280 A:middle L:90% rating was fine tuning that bulk grating and we held 709 00:42:07.289 --> 00:42:09.469 A:middle L:90% a constant elevation for the finish floor, still two 710 00:42:09.469 --> 00:42:12.380 A:middle L:90% ft above the proposed roadway, and then we have 711 00:42:12.380 --> 00:42:15.630 A:middle L:90% a 5% grade sloping for 10 ft out from the 712 00:42:15.639 --> 00:42:17.079 A:middle L:90% finished floor, which equates to about half a foot 713 00:42:17.079 --> 00:42:21.179 A:middle L:90% drop over 10 ft. And lastly, we added 714 00:42:21.179 --> 00:42:22.090 A:middle L:90% a sway on the back to account for the drainage 715 00:42:22.099 --> 00:42:24.150 A:middle L:90% because this is a long, hard look in court 716 00:42:24.159 --> 00:42:27.119 A:middle L:90% . We had a large green space over here and 717 00:42:27.119 --> 00:42:29.489 A:middle L:90% there will be a lot of stormwater to talk about 718 00:42:29.489 --> 00:42:30.510 A:middle L:90% . And that's where we'll go next with Katie. 719 00:42:32.500 --> 00:42:35.230 A:middle L:90% So I'm gonna talk a little bit about the storm 720 00:42:35.230 --> 00:42:37.099 A:middle L:90% water here. You can see our pre development watershed 721 00:42:37.099 --> 00:42:39.449 A:middle L:90% , you can see it's mostly in one watershed heading 722 00:42:39.449 --> 00:42:42.500 A:middle L:90% to this low point down here is marked by the 723 00:42:42.500 --> 00:42:45.469 A:middle L:90% green X. We use the rational method and we 724 00:42:45.480 --> 00:42:47.929 A:middle L:90% used three different type of concentration lines also going to 725 00:42:47.929 --> 00:42:51.829 A:middle L:90% that one point to find that our total pre development 726 00:42:51.840 --> 00:42:54.840 A:middle L:90% flow rate was 23 cubic feet per second. And 727 00:42:54.840 --> 00:42:58.820 A:middle L:90% here you can see all of our post development watershed 728 00:42:58.820 --> 00:43:01.889 A:middle L:90% delineations, all also flowing down to this final point 729 00:43:01.900 --> 00:43:07.489 A:middle L:90% and our total post development watershed or flow rate was 730 00:43:07.489 --> 00:43:10.900 A:middle L:90% 29 cubic feet per second. Here. You can 731 00:43:10.900 --> 00:43:15.289 A:middle L:90% see our proposed stormwater lines which are sharing in the 732 00:43:15.300 --> 00:43:20.340 A:middle L:90% dark color. We decided to tie into existing inlets 733 00:43:20.349 --> 00:43:22.469 A:middle L:90% on George mason boulevard. There are seven of those 734 00:43:22.469 --> 00:43:27.000 A:middle L:90% as seen by the darker blue. And we also 735 00:43:27.010 --> 00:43:30.699 A:middle L:90% chose to install 12 new inlets, which are known 736 00:43:30.699 --> 00:43:31.880 A:middle L:90% by the lighter blue. Those we placed in low 737 00:43:31.880 --> 00:43:36.559 A:middle L:90% points or before intersections to prevent too much water from 738 00:43:36.570 --> 00:43:42.139 A:middle L:90% entering intersections or ponding on the site. In order 739 00:43:42.139 --> 00:43:44.670 A:middle L:90% to make up for the difference between the pre development 740 00:43:44.670 --> 00:43:46.239 A:middle L:90% and put post development flow rates, we decided to 741 00:43:46.239 --> 00:43:51.340 A:middle L:90% install, install a detention pond down here. Um 742 00:43:51.349 --> 00:43:53.159 A:middle L:90% This would have to be about 0.17 acre feet, 743 00:43:53.159 --> 00:43:58.780 A:middle L:90% which is about 7500 cubic feet. Um Since there's 744 00:43:58.780 --> 00:44:00.409 A:middle L:90% an existing Swail in this location, it made sense 745 00:44:00.409 --> 00:44:02.340 A:middle L:90% to place it here, especially since all the water 746 00:44:02.340 --> 00:44:05.400 A:middle L:90% was drained from there. So there didn't have to 747 00:44:05.400 --> 00:44:07.500 A:middle L:90% be a whole lot of drastic grading changes made since 748 00:44:07.500 --> 00:44:10.309 A:middle L:90% there is also an existing outlet structure there as well 749 00:44:12.090 --> 00:44:15.219 A:middle L:90% . Also required by Fairfax County are best management practices 750 00:44:15.230 --> 00:44:16.940 A:middle L:90% . So we looked into what would be our best 751 00:44:16.949 --> 00:44:21.230 A:middle L:90% options and we ended up settling with dry swells since 752 00:44:21.230 --> 00:44:23.440 A:middle L:90% they would reduce the amount of water exiting the site 753 00:44:23.449 --> 00:44:27.829 A:middle L:90% as it flows through. Now, I'm going to 754 00:44:27.829 --> 00:44:30.380 A:middle L:90% move into a little bit about the erosion sediment control 755 00:44:30.380 --> 00:44:31.690 A:middle L:90% plants. We decided to line most of the site 756 00:44:31.690 --> 00:44:36.309 A:middle L:90% with super silt fence, which would prevent water from 757 00:44:36.320 --> 00:44:37.480 A:middle L:90% our dirt from flowing off of the site as grading 758 00:44:37.480 --> 00:44:40.820 A:middle L:90% is occurring in stockpiles of soil are building up. 759 00:44:40.829 --> 00:44:45.409 A:middle L:90% We also put in diversion dykes either to direct water 760 00:44:45.409 --> 00:44:47.429 A:middle L:90% towards a settlement basin or sediment traps as well as 761 00:44:47.429 --> 00:44:51.019 A:middle L:90% to keep clean water from coming in off of the 762 00:44:51.019 --> 00:44:53.079 A:middle L:90% site on the west side. Um we have one 763 00:44:53.079 --> 00:44:58.789 A:middle L:90% sentiment basin where the uh detention pond and mentioned earlier 764 00:44:58.789 --> 00:45:02.079 A:middle L:90% would be going and it's also construction entrances to prevent 765 00:45:02.090 --> 00:45:05.489 A:middle L:90% trucks from tracking dirt on and off the site as 766 00:45:05.500 --> 00:45:08.320 A:middle L:90% they move as needed, temporary seating will be installed 767 00:45:08.329 --> 00:45:12.969 A:middle L:90% up until final design, which you can see here 768 00:45:12.980 --> 00:45:15.559 A:middle L:90% as we put in the inlets that I discussed earlier 769 00:45:15.570 --> 00:45:19.309 A:middle L:90% , we would add inlet protection and remove the sediment 770 00:45:19.309 --> 00:45:21.789 A:middle L:90% traps we had on the east side, the sediment 771 00:45:21.789 --> 00:45:24.170 A:middle L:90% basin and the diversion dykes leading to that sediment basins 772 00:45:24.179 --> 00:45:27.730 A:middle L:90% as well as the super silt fence around the site 773 00:45:27.739 --> 00:45:30.230 A:middle L:90% would stay in place until design is complete and then 774 00:45:30.230 --> 00:45:34.289 A:middle L:90% the sediment basin would be turned into that detention pond 775 00:45:34.579 --> 00:45:35.760 A:middle L:90% . And now I'm going to pass it over to 776 00:45:35.760 --> 00:45:37.030 A:middle L:90% dan. I'm gonna talk a little bit about the 777 00:45:37.039 --> 00:45:40.659 A:middle L:90% wet utilities here. You can see we have both 778 00:45:40.670 --> 00:45:45.269 A:middle L:90% sewer and water. They're in their own separate lanes 779 00:45:45.280 --> 00:45:46.469 A:middle L:90% in the roadway so that we can meet the 10-foot 780 00:45:46.469 --> 00:45:51.369 A:middle L:90% horizontal. An 18 ft or 18 excuse me, 781 00:45:51.579 --> 00:45:55.719 A:middle L:90% separation requirement. The sanitary line proposed uh, its 782 00:45:55.719 --> 00:46:00.460 A:middle L:90% own unique problem because our only existing tying is up 783 00:46:00.460 --> 00:46:02.590 A:middle L:90% in the northwest corner here, which is actually one 784 00:46:02.590 --> 00:46:05.679 A:middle L:90% of the highest point on the site. We weren't 785 00:46:05.679 --> 00:46:07.760 A:middle L:90% able to gravity feed all of our sewage to that 786 00:46:07.769 --> 00:46:09.679 A:middle L:90% point. So we had to do was designed to 787 00:46:09.679 --> 00:46:12.699 A:middle L:90% bring all the sewage to the low point on our 788 00:46:12.699 --> 00:46:15.960 A:middle L:90% site and then installed pump station, which will bring 789 00:46:15.960 --> 00:46:19.099 A:middle L:90% all that sewage back up to the top. The 790 00:46:19.110 --> 00:46:23.469 A:middle L:90% lines are eight PVC And are designed to hold 68,000 791 00:46:23.469 --> 00:46:28.179 A:middle L:90% gallons per day. The water system we didn't have 792 00:46:28.190 --> 00:46:30.969 A:middle L:90% any problems with. There's an existing six inch line 793 00:46:30.980 --> 00:46:32.480 A:middle L:90% up in the north here and a 12 inch line 794 00:46:32.489 --> 00:46:36.150 A:middle L:90% down here to the south, Which made it really 795 00:46:36.150 --> 00:46:37.019 A:middle L:90% easy for us to loop our water lines together, 796 00:46:37.019 --> 00:46:39.909 A:middle L:90% which is a requirement for Fairfax County. And this 797 00:46:39.909 --> 00:46:45.579 A:middle L:90% is an eight ductile iron pipe That supports 30,000 gallons 798 00:46:45.579 --> 00:46:49.599 A:middle L:90% per day for the residents and a 6700 gallons per 799 00:46:49.599 --> 00:46:52.960 A:middle L:90% minute fire flow requirement. Lastly, is our cost 800 00:46:52.969 --> 00:46:57.260 A:middle L:90% . The final cost of our project was$1.31 million 801 00:46:57.579 --> 00:47:00.710 A:middle L:90% . Some of the major cost for this project Where 802 00:47:00.719 --> 00:47:04.349 A:middle L:90% the storm pipe, especially 24 storm pipe near the 803 00:47:04.349 --> 00:47:07.840 A:middle L:90% outfall location. Uh huh. The PVC for the 804 00:47:07.840 --> 00:47:10.099 A:middle L:90% sanitary, the doctor, iron pipe for the water 805 00:47:10.099 --> 00:47:14.710 A:middle L:90% lines and then obviously roadways and driveways were a huge 806 00:47:14.710 --> 00:47:17.769 A:middle L:90% cost for a development like this. And does anybody 807 00:47:17.769 --> 00:47:25.650 A:middle L:90% have any questions? Great. Did you have to 808 00:47:25.650 --> 00:47:29.860 A:middle L:90% consider any traffic control and crossing the road? Yes 809 00:47:29.869 --> 00:47:31.119 A:middle L:90% , that's why we decided to go with the first 810 00:47:31.119 --> 00:47:36.489 A:middle L:90% conceptual design with only one intersection. It was like 811 00:47:36.500 --> 00:47:38.349 A:middle L:90% just about in between the two existing intersections. And 812 00:47:38.349 --> 00:47:39.769 A:middle L:90% I actually got a chance to go look at the 813 00:47:39.769 --> 00:47:42.699 A:middle L:90% site and I lived near there a couple of summers 814 00:47:42.699 --> 00:47:44.429 A:middle L:90% ago so I knew that it could get a little 815 00:47:44.429 --> 00:47:47.300 A:middle L:90% crowded, especially um with the traffic in northern Virginia 816 00:47:47.309 --> 00:47:50.099 A:middle L:90% , but we figured it wouldn't be a problem because 817 00:47:50.099 --> 00:47:52.099 A:middle L:90% it stayed away from most of the existing turn lanes 818 00:47:59.980 --> 00:48:01.760 A:middle L:90% . Yeah, no questions asked a lot of. 819 00:48:01.760 --> 00:48:16.000 A:middle L:90% All right. Thank you. Yeah. Right. 820 00:48:19.269 --> 00:48:22.320 A:middle L:90% All right. It's a pleasure to welcome you all 821 00:48:22.320 --> 00:48:25.059 A:middle L:90% to our presentation. My name is moses, I'm 822 00:48:25.059 --> 00:48:30.099 A:middle L:90% paige, Crawford, brian Graham and we got LMRP 823 00:48:30.099 --> 00:48:32.590 A:middle L:90% consultants. We will be talking about a project which 824 00:48:32.590 --> 00:48:37.929 A:middle L:90% we called to help Plaza and we're mentor by uh 825 00:48:37.940 --> 00:48:39.900 A:middle L:90% All right guys and bought it back there. Yes 826 00:48:40.369 --> 00:48:43.460 A:middle L:90% . Uh just a brief overview of the present. 827 00:48:43.469 --> 00:48:46.039 A:middle L:90% I'm sorry the presentation will talk about some of the 828 00:48:46.050 --> 00:48:51.460 A:middle L:90% layout characteristics and uh design and then we'll open the 829 00:48:51.460 --> 00:48:54.639 A:middle L:90% floor for questions if you guys have any. Our 830 00:48:54.639 --> 00:48:58.090 A:middle L:90% site is located, it will first off will be 831 00:48:58.090 --> 00:49:00.190 A:middle L:90% a commercial development. Um it will consist of seven 832 00:49:00.190 --> 00:49:04.670 A:middle L:90% buildings uh re sole source and then one of them 833 00:49:04.670 --> 00:49:06.500 A:middle L:90% will be a restaurant and the other one will be 834 00:49:06.500 --> 00:49:08.730 A:middle L:90% a grocery store. It is located in Lynchburg Virginia 835 00:49:08.739 --> 00:49:12.679 A:middle L:90% about 100 miles away from here is not too far 836 00:49:12.690 --> 00:49:14.969 A:middle L:90% . Uh It's total area, it's about six point 837 00:49:14.969 --> 00:49:20.039 A:middle L:90% point 6.4 acres and with it has about 250 ft 838 00:49:20.039 --> 00:49:23.699 A:middle L:90% of frontage, It is only be five so that 839 00:49:23.710 --> 00:49:27.650 A:middle L:90% that was perfect for our development because it fits are 840 00:49:27.650 --> 00:49:30.409 A:middle L:90% intended purpose. Also, I want to point out 841 00:49:30.409 --> 00:49:32.510 A:middle L:90% that the two properties that are close to our site 842 00:49:32.519 --> 00:49:37.760 A:middle L:90% , there's a residence up there and then another story 843 00:49:37.760 --> 00:49:39.139 A:middle L:90% right here at enterprise rent a car that would also 844 00:49:39.139 --> 00:49:45.780 A:middle L:90% zone B five that greatly reduce our any major problems 845 00:49:45.780 --> 00:49:47.539 A:middle L:90% with zoning, uh, set bags any of that 846 00:49:47.550 --> 00:49:50.710 A:middle L:90% . So we didn't have any issues uh in that 847 00:49:50.710 --> 00:49:54.190 A:middle L:90% sense, that's this is our final conceptual layout. 848 00:49:54.570 --> 00:50:00.179 A:middle L:90% We ended up putting five kind of five concentrated buildings 849 00:50:00.179 --> 00:50:04.289 A:middle L:90% in this part of the site without big parking lot 850 00:50:04.289 --> 00:50:06.840 A:middle L:90% . Right here, we created two roads, La 851 00:50:06.840 --> 00:50:12.230 A:middle L:90% Voisin Race Lane, um and just to give you 852 00:50:12.230 --> 00:50:14.269 A:middle L:90% guys a better idea of what it would look like 853 00:50:14.860 --> 00:50:16.309 A:middle L:90% . Uh This is uh the animation, this is 854 00:50:16.309 --> 00:50:19.829 A:middle L:90% the current state of the site. It's probably wouldn 855 00:50:19.840 --> 00:50:22.329 A:middle L:90% it's uh surrounded by three roads road, lakeside drive 856 00:50:22.329 --> 00:50:25.789 A:middle L:90% and all forest road. There's this big parking lot 857 00:50:25.789 --> 00:50:28.349 A:middle L:90% right here. As I said, we'll serve these 858 00:50:28.349 --> 00:50:31.159 A:middle L:90% five buildings. Uh uh That would be great because 859 00:50:31.159 --> 00:50:35.019 A:middle L:90% it has two entrances along this, this side of 860 00:50:35.019 --> 00:50:37.320 A:middle L:90% the of the development will be to hundreds in the 861 00:50:37.329 --> 00:50:43.090 A:middle L:90% back which we designed for employees and uh trucks. 862 00:50:43.099 --> 00:50:45.980 A:middle L:90% You can see the loading docks right here to which 863 00:50:45.989 --> 00:50:49.210 A:middle L:90% we thought would be added for convenience, getting in 864 00:50:49.210 --> 00:50:52.880 A:middle L:90% our decide for normal customers. There is also parking 865 00:50:52.889 --> 00:50:54.539 A:middle L:90% in front of the stores. Uh so that added 866 00:50:54.550 --> 00:50:59.210 A:middle L:90% uh just more comfort to the users of the site 867 00:50:59.219 --> 00:51:00.610 A:middle L:90% . Some of these stories we do know about Petrino 868 00:51:00.610 --> 00:51:06.769 A:middle L:90% Petko will be there and the uh restaurant Bonaire will 869 00:51:06.780 --> 00:51:07.650 A:middle L:90% be up there too. But some of them would 870 00:51:07.650 --> 00:51:10.889 A:middle L:90% just the by any means are are on the side 871 00:51:10.889 --> 00:51:15.880 A:middle L:90% of the on site. They're going up top, 872 00:51:15.889 --> 00:51:19.690 A:middle L:90% there is an entrance right here along all forest road 873 00:51:19.699 --> 00:51:22.690 A:middle L:90% which will primarily serve these two buildings, the restaurant 874 00:51:22.699 --> 00:51:24.639 A:middle L:90% , which is a um kind of by itself. 875 00:51:24.650 --> 00:51:27.260 A:middle L:90% But there is this parking lot right here. We 876 00:51:27.260 --> 00:51:30.909 A:middle L:90% should we add to serve those two buildings. So 877 00:51:30.909 --> 00:51:32.179 A:middle L:90% this is pretty much what this would look like, 878 00:51:32.559 --> 00:51:35.769 A:middle L:90% the idea of it. Uh I want to point 879 00:51:35.769 --> 00:51:39.079 A:middle L:90% out the entrances broke, normal entrances to customers. 880 00:51:39.090 --> 00:51:42.519 A:middle L:90% One of the two of them will be along Lakeside 881 00:51:42.519 --> 00:51:45.230 A:middle L:90% drive and one of them on all Forest Road. 882 00:51:45.239 --> 00:51:49.579 A:middle L:90% Also, there will be, as I said, 883 00:51:49.590 --> 00:51:53.280 A:middle L:90% the entrance is for employees and trucks on Whitehall Road 884 00:51:55.559 --> 00:51:58.570 A:middle L:90% . Someone talk a little about ready. Um, 885 00:51:59.059 --> 00:52:00.349 A:middle L:90% So as you can see, you know, we 886 00:52:00.349 --> 00:52:00.710 A:middle L:90% have a lot of flat area on our site. 887 00:52:00.719 --> 00:52:04.869 A:middle L:90% We got about 74,000 square feet of buildings, which 888 00:52:04.869 --> 00:52:07.300 A:middle L:90% is about 1.5 acres. A little over that on 889 00:52:07.300 --> 00:52:08.059 A:middle L:90% a six acre site. That was a lot to 890 00:52:08.070 --> 00:52:12.239 A:middle L:90% do because before we touch the site went from 844 891 00:52:12.239 --> 00:52:14.730 A:middle L:90% ft all way down to 840, so there was 892 00:52:14.730 --> 00:52:15.070 A:middle L:90% a whole lot of great that went on there. 893 00:52:15.550 --> 00:52:17.909 A:middle L:90% Um Due to that, we have to employ a 894 00:52:17.909 --> 00:52:20.829 A:middle L:90% couple measures, the first of which is retaining walls 895 00:52:20.829 --> 00:52:21.889 A:middle L:90% as you can see. We have four of them 896 00:52:21.900 --> 00:52:24.070 A:middle L:90% versus runs right down the side here. 2nd over 897 00:52:24.070 --> 00:52:29.000 A:middle L:90% here, they're down here And forth along here and 898 00:52:29.010 --> 00:52:30.070 A:middle L:90% they run from about three ft to about seven ft 899 00:52:30.070 --> 00:52:32.360 A:middle L:90% tall. Um as I said, with that much 900 00:52:32.360 --> 00:52:36.130 A:middle L:90% flat space in such a large area, we really 901 00:52:36.130 --> 00:52:37.980 A:middle L:90% need that to make all the difference in grades everywhere 902 00:52:38.449 --> 00:52:40.980 A:middle L:90% . And another thing we used as well was the 903 00:52:40.980 --> 00:52:44.130 A:middle L:90% Swales, as you can see along some of the 904 00:52:44.230 --> 00:52:45.380 A:middle L:90% walls here, it's raining well here and part of 905 00:52:45.380 --> 00:52:47.969 A:middle L:90% this retaining wall, we employed Swales in order to 906 00:52:47.980 --> 00:52:50.349 A:middle L:90% make sure we were really drinking the water where we 907 00:52:50.349 --> 00:52:51.719 A:middle L:90% wanted to be to make sure that we're all heading 908 00:52:51.719 --> 00:52:53.570 A:middle L:90% downhill because as you can fairly well see by the 909 00:52:53.570 --> 00:52:57.460 A:middle L:90% site, um grading plan, it's all sloping from 910 00:52:57.460 --> 00:52:59.969 A:middle L:90% the northwest down to the southeast because there is existing 911 00:53:00.250 --> 00:53:01.380 A:middle L:90% , so um are dying down here as you can 912 00:53:01.380 --> 00:53:05.289 A:middle L:90% see all the finished wild asians are set and they 913 00:53:05.300 --> 00:53:08.110 A:middle L:90% range greatly uh which made it fairly tricky to tie 914 00:53:08.110 --> 00:53:10.219 A:middle L:90% in with the sidewalk. You know, we tried 915 00:53:10.219 --> 00:53:13.039 A:middle L:90% to keep it as flat as we could, but 916 00:53:13.039 --> 00:53:14.400 A:middle L:90% we had to use a lot of ramps for instance 917 00:53:14.400 --> 00:53:15.340 A:middle L:90% , in front of here there's two ramps and we 918 00:53:15.340 --> 00:53:16.840 A:middle L:90% actually used a set of stairs are here to make 919 00:53:16.840 --> 00:53:20.190 A:middle L:90% up the great between the grocery store and the retail 920 00:53:20.190 --> 00:53:22.019 A:middle L:90% center as well as the parking lot was fairly big 921 00:53:22.019 --> 00:53:24.119 A:middle L:90% job that is a huge area there to keep flat 922 00:53:24.119 --> 00:53:27.269 A:middle L:90% and such a, you know, sloped site. 923 00:53:27.449 --> 00:53:30.710 A:middle L:90% We maintain a maximum five While keeping the two cross 924 00:53:30.710 --> 00:53:32.929 A:middle L:90% slope as well as the 88 spots, which aren't 925 00:53:32.940 --> 00:53:36.869 A:middle L:90% actually showed on here, but they are right here 926 00:53:36.880 --> 00:53:38.710 A:middle L:90% , right here up here then except for there. 927 00:53:38.719 --> 00:53:42.489 A:middle L:90% But those had to be two across the entire thing 928 00:53:42.489 --> 00:53:43.690 A:middle L:90% . So that was a little bit of a challenge 929 00:53:43.690 --> 00:53:45.389 A:middle L:90% as well as all this talk in front of buildings 930 00:53:45.389 --> 00:53:47.079 A:middle L:90% here and here where there's no ramps and over here 931 00:53:47.090 --> 00:53:49.880 A:middle L:90% all had to be kept at two as well. 932 00:53:50.449 --> 00:53:52.210 A:middle L:90% Um Additionally, as I said, the whole study 933 00:53:52.210 --> 00:53:54.800 A:middle L:90% was tried to be designed so that we did keep 934 00:53:54.800 --> 00:53:57.320 A:middle L:90% the existing as much as we could, but still 935 00:53:57.320 --> 00:53:59.590 A:middle L:90% tied into the existing storm water down here to the 936 00:53:59.590 --> 00:54:00.860 A:middle L:90% right. We also, as we talked about how 937 00:54:00.860 --> 00:54:04.010 A:middle L:90% the entrance of employees in the back here along Whitehall 938 00:54:04.019 --> 00:54:06.039 A:middle L:90% , which works well because there's not much traffic, 939 00:54:06.039 --> 00:54:07.969 A:middle L:90% it's a much smaller road compared to other too. 940 00:54:07.239 --> 00:54:08.670 A:middle L:90% Um So I'll make a lot easier for the large 941 00:54:08.670 --> 00:54:10.369 A:middle L:90% trucks come in and we have to sign the two 942 00:54:10.369 --> 00:54:13.579 A:middle L:90% truck bed as you can see right here and right 943 00:54:13.579 --> 00:54:20.219 A:middle L:90% here for the deliveries to the largest doors. There 944 00:54:20.219 --> 00:54:23.119 A:middle L:90% is a total drainage area of 7.52 acres on this 945 00:54:23.119 --> 00:54:28.099 A:middle L:90% site, which was divided between 21 inlets. There 946 00:54:28.110 --> 00:54:31.590 A:middle L:90% are three pipe networks, which there's one along the 947 00:54:31.599 --> 00:54:35.929 A:middle L:90% west side of the site here connecting to the storage 948 00:54:35.929 --> 00:54:37.880 A:middle L:90% tank or underground water storage tank. And there's one 949 00:54:37.889 --> 00:54:43.599 A:middle L:90% connecting the north and east uh inlets and there's one 950 00:54:43.599 --> 00:54:45.090 A:middle L:90% connecting the two south side and let's, and then 951 00:54:45.090 --> 00:54:49.579 A:middle L:90% there is a outlet structure that connects to the existing 952 00:54:49.579 --> 00:54:51.860 A:middle L:90% storm water pipe on the south side of the site 953 00:54:52.940 --> 00:54:55.750 A:middle L:90% . Um all the pipes range from 18 to 42" 954 00:54:58.239 --> 00:55:01.400 A:middle L:90% . So we used an underground water storage tank because 955 00:55:01.409 --> 00:55:06.719 A:middle L:90% there wasn't enough area for a detention basin on the 956 00:55:06.719 --> 00:55:10.579 A:middle L:90% site. The storage tank was located in the south 957 00:55:10.579 --> 00:55:13.679 A:middle L:90% side of the site of the one of the lowest 958 00:55:13.690 --> 00:55:16.090 A:middle L:90% elevations and is in the parking lot area to avoid 959 00:55:16.099 --> 00:55:22.429 A:middle L:90% building pads in any construction problems. The Um storage 960 00:55:22.429 --> 00:55:24.539 A:middle L:90% tank is 34 ft by 34 ft by 11 ft 961 00:55:24.550 --> 00:55:29.030 A:middle L:90% , which was used. Um that was calculated by 962 00:55:29.039 --> 00:55:32.800 A:middle L:90% finding the Um volume needed from the hydrographic, which 963 00:55:32.800 --> 00:55:38.519 A:middle L:90% was 9,822 cubic feet of water storage and we found 964 00:55:38.519 --> 00:55:42.489 A:middle L:90% out that it out falls at a rate of 10.16 965 00:55:42.500 --> 00:55:46.130 A:middle L:90% cubic feet. This is the outfall structure that connects 966 00:55:46.130 --> 00:55:51.539 A:middle L:90% to the existing um storm structure and we sloped it 967 00:55:51.539 --> 00:55:54.000 A:middle L:90% up at.5 to the water storage tank and that 968 00:55:54.000 --> 00:56:00.239 A:middle L:90% set the elevation for the storage tank invert at okay 969 00:56:00.929 --> 00:56:10.670 A:middle L:90% at 800 And 1.801.61. And then um the tent 970 00:56:10.670 --> 00:56:15.420 A:middle L:90% goes up 11 ft and allows for 2.5 ft of 971 00:56:15.429 --> 00:56:20.969 A:middle L:90% free board. We used um sand filters for BMP 972 00:56:20.980 --> 00:56:22.440 A:middle L:90% options and we used the D. C. Underground 973 00:56:22.449 --> 00:56:31.039 A:middle L:90% fault sand filter at 16 different England's. Okay. 974 00:56:31.050 --> 00:56:35.250 A:middle L:90% These are the existing what utilities around the site? 975 00:56:35.829 --> 00:56:39.489 A:middle L:90% Um this magenta is existing sanitary sewer which is eight 976 00:56:39.489 --> 00:56:45.179 A:middle L:90% in diameter and this water line is existing um going 977 00:56:45.179 --> 00:56:49.840 A:middle L:90% around all forest Lane and then wait whole road. 978 00:56:51.130 --> 00:56:54.380 A:middle L:90% These are proposed. What utilities we have a water 979 00:56:54.380 --> 00:57:00.340 A:middle L:90% line water main coming from this existing around the site 980 00:57:00.030 --> 00:57:02.380 A:middle L:90% . Um And ending up there it creates a loop 981 00:57:02.380 --> 00:57:07.579 A:middle L:90% system which is a factor of safety in case anywhere 982 00:57:07.590 --> 00:57:09.010 A:middle L:90% in the pipe there is a break um It can 983 00:57:09.010 --> 00:57:13.210 A:middle L:90% be serviced from the other side and we have laterals 984 00:57:13.219 --> 00:57:17.630 A:middle L:90% going to each building and then our sanitary sewer begins 985 00:57:17.630 --> 00:57:20.800 A:middle L:90% . We have two different networks for that. The 986 00:57:20.809 --> 00:57:24.099 A:middle L:90% first one begins here and comes up to the existing 987 00:57:24.110 --> 00:57:28.300 A:middle L:90% and then the other one begins here and ends of 988 00:57:28.309 --> 00:57:32.840 A:middle L:90% the existing right there And that is an eight diameter 989 00:57:32.849 --> 00:57:37.130 A:middle L:90% PVC pipe and we have the laterals connecting to each 990 00:57:37.130 --> 00:57:42.059 A:middle L:90% building. Um These two networks only cost in one 991 00:57:42.059 --> 00:57:45.170 A:middle L:90% spot which was right here And we had the water 992 00:57:45.179 --> 00:57:50.539 A:middle L:90% over the sanitary by at least 18 and you can 993 00:57:50.539 --> 00:57:55.949 A:middle L:90% see along here there separated by 10 ft horizontally. 994 00:58:02.920 --> 00:58:07.760 A:middle L:90% Yeah, our final project policy cost was about uh 995 00:58:07.769 --> 00:58:13.099 A:middle L:90% $2.5 million. We managed to change some of the 996 00:58:13.099 --> 00:58:15.960 A:middle L:90% features such as retaining walls, that diameter and number 997 00:58:15.960 --> 00:58:19.380 A:middle L:90% of inlets to reduce it by 10% to provide the 998 00:58:19.389 --> 00:58:23.239 A:middle L:90% client with lesser price more affordable. And the with 999 00:58:23.239 --> 00:58:27.489 A:middle L:90% the 10% savings, Uh it came down to be 1000 00:58:27.500 --> 00:58:31.809 A:middle L:90% uh$2.22.2 million. Tell us the presentation. Um 1001 00:58:31.820 --> 00:58:37.050 A:middle L:90% You guys have any questions? Yes. Yes. 1002 00:58:38.119 --> 00:58:43.300 A:middle L:90% Storm of paint. Mhm. 34 34 11. 1003 00:58:43.309 --> 00:58:46.969 A:middle L:90% Quickie Vision that being constructed? Sorry, what was 1004 00:58:46.969 --> 00:58:51.059 A:middle L:90% that? What we envisioned that? Okay, what 1005 00:58:51.070 --> 00:58:54.000 A:middle L:90% what will be made? Hell you constructed? There 1006 00:58:54.000 --> 00:58:58.949 A:middle L:90% are companies that you can just give them the dimensions 1007 00:58:58.949 --> 00:59:00.739 A:middle L:90% and whatever you need and they'll construct that. I'm 1008 00:59:00.739 --> 00:59:05.130 A:middle L:90% not exactly sure what material is used. I'm assuming 1009 00:59:05.130 --> 00:59:08.170 A:middle L:90% some sort of reinforced concrete, but I'm not exactly 1010 00:59:08.170 --> 00:59:16.840 A:middle L:90% sure my questions. Do you think your most difficult 1011 00:59:17.219 --> 00:59:21.590 A:middle L:90% part of this whole project site with a lot of 1012 00:59:21.599 --> 00:59:23.099 A:middle L:90% probably created just thinking back to the most. Just 1013 00:59:23.099 --> 00:59:25.769 A:middle L:90% getting it all worked out moving forward. No other 1014 00:59:25.780 --> 00:59:28.829 A:middle L:90% things in mind. You know the way utilities and 1015 00:59:28.829 --> 00:59:30.489 A:middle L:90% store water, trying to entertain all that while making 1016 00:59:30.500 --> 00:59:32.340 A:middle L:90% sure that, you know, one of the half 1017 00:59:32.619 --> 00:59:35.739 A:middle L:90% acres was flat on that six of yourself, because 1018 00:59:35.739 --> 00:59:36.889 A:middle L:90% that was a 50 ft. So I was pretty 1019 00:59:36.889 --> 00:59:37.900 A:middle L:90% tricky putting all the cannonballs and just right, getting 1020 00:59:37.900 --> 00:59:40.059 A:middle L:90% the scales done, How to F five biggest challenge 1021 00:59:40.059 --> 00:59:45.530 A:middle L:90% rest cast out here. All non match. Well 1022 00:59:45.530 --> 00:59:59.719 A:middle L:90% done. Yeah. Good morning. Everybody were the 1023 00:59:59.719 --> 01:00:01.530 A:middle L:90% group from Tri Tech Engineering and we designed the Tall 1024 01:00:01.530 --> 01:00:05.639 A:middle L:90% Oaks commercial flex industrial Development. My name is Bill 1025 01:00:05.639 --> 01:00:07.619 A:middle L:90% Mackey. I'm erin Bartley, Pat smith. All 1026 01:00:07.619 --> 01:00:09.829 A:middle L:90% right. Just a quick overview of our presentation real 1027 01:00:09.829 --> 01:00:12.579 A:middle L:90% quick. I'm just gonna be going over the initial 1028 01:00:12.579 --> 01:00:15.159 A:middle L:90% client goals and introduction as well as the grading and 1029 01:00:15.159 --> 01:00:16.889 A:middle L:90% erosion sediment control while Aaron will be going over storm 1030 01:00:16.889 --> 01:00:19.690 A:middle L:90% network and that will be going into the water and 1031 01:00:19.690 --> 01:00:22.840 A:middle L:90% sanitary as well as the conclusion. Um So our 1032 01:00:22.840 --> 01:00:24.360 A:middle L:90% site location, I'm just relevant from here. It 1033 01:00:24.360 --> 01:00:27.710 A:middle L:90% is in northern Virginia is located in Loudoun County, 1034 01:00:27.710 --> 01:00:29.650 A:middle L:90% so if everybody knows where they are here it's about 1035 01:00:29.650 --> 01:00:32.070 A:middle L:90% 4.5 hours um northeast of here. So I'm sure 1036 01:00:32.070 --> 01:00:35.550 A:middle L:90% a lot of you guys are from northern Virginia and 1037 01:00:35.559 --> 01:00:37.719 A:middle L:90% it's located just outside of Washington D. C. 1038 01:00:37.719 --> 01:00:39.820 A:middle L:90% To the west between rested and leesburg right there. 1039 01:00:40.010 --> 01:00:44.230 A:middle L:90% Um it's just outside the 495 felt. But Um 1040 01:00:44.230 --> 01:00:45.980 A:middle L:90% so here's our existing conditions site. Um it's about 1041 01:00:45.980 --> 01:00:51.590 A:middle L:90% 10 acres and it's completely um wooded and it's undeveloped 1042 01:00:51.590 --> 01:00:53.469 A:middle L:90% . Currently it is in a pretty or pretty commercial 1043 01:00:53.469 --> 01:00:58.289 A:middle L:90% district as you can see by the by the two 1044 01:00:58.300 --> 01:01:00.579 A:middle L:90% parking lots and large buildings and it's located or it's 1045 01:01:00.579 --> 01:01:04.579 A:middle L:90% a zone for a planned development industrial park. So 1046 01:01:04.579 --> 01:01:07.110 A:middle L:90% as we're going to be developing an industrial facility, 1047 01:01:07.110 --> 01:01:08.019 A:middle L:90% we didn't need to change the zoning at all. 1048 01:01:08.030 --> 01:01:12.880 A:middle L:90% Um there's no existing utilities on site and it's actually 1049 01:01:12.880 --> 01:01:15.210 A:middle L:90% currently a gravel road that's the only access to the 1050 01:01:15.210 --> 01:01:17.130 A:middle L:90% site that runs along the north right there and it's 1051 01:01:17.130 --> 01:01:22.179 A:middle L:90% an extension of Marie's Word which is paved and the 1052 01:01:22.190 --> 01:01:24.110 A:middle L:90% site is very flat actually with 0 to 5% slopes 1053 01:01:24.119 --> 01:01:27.690 A:middle L:90% and there's wetlands at the north of the site right 1054 01:01:27.690 --> 01:01:29.610 A:middle L:90% there, it's about a third of an acre and 1055 01:01:29.610 --> 01:01:31.730 A:middle L:90% we're actually going to remove those wetlands. Um so 1056 01:01:31.739 --> 01:01:35.469 A:middle L:90% client goals. Um the improvement of Marie's road was 1057 01:01:35.469 --> 01:01:37.659 A:middle L:90% a big thing on the end of the paved road 1058 01:01:37.670 --> 01:01:39.219 A:middle L:90% is significantly north of the side, about 500 ft 1059 01:01:39.230 --> 01:01:42.619 A:middle L:90% . And we have to actually pave the road all 1060 01:01:42.619 --> 01:01:44.769 A:middle L:90% the way down to the bottom to the south of 1061 01:01:44.769 --> 01:01:46.840 A:middle L:90% our site. And um as well as designed to 1062 01:01:46.849 --> 01:01:50.489 A:middle L:90% flex industrial facility, which, if you're not familiar 1063 01:01:50.489 --> 01:01:53.039 A:middle L:90% with what that is, it's basically a large 50-75,000 1064 01:01:53.039 --> 01:01:57.800 A:middle L:90% square foot building and it's mostly a large warehouse and 1065 01:01:57.809 --> 01:02:01.679 A:middle L:90% it has 25-35 office space with parking and it has 1066 01:02:01.679 --> 01:02:05.489 A:middle L:90% loading Bay is located along the back. This building 1067 01:02:05.489 --> 01:02:07.239 A:middle L:90% is roughly 100 x 500 ft, so it's very 1068 01:02:07.239 --> 01:02:12.039 A:middle L:90% long and rectangular to allow Extra loading areas and the 1069 01:02:12.050 --> 01:02:15.360 A:middle L:90% pavement elevation is actually four ft below the finished floor 1070 01:02:15.360 --> 01:02:19.449 A:middle L:90% elevation, which was significant in our grading. So 1071 01:02:19.449 --> 01:02:21.559 A:middle L:90% here's our site plan overview. This is actually our 1072 01:02:21.559 --> 01:02:23.889 A:middle L:90% conceptual layout from the beginning. We as we had 1073 01:02:23.889 --> 01:02:27.340 A:middle L:90% to design for two buildings. The building to the 1074 01:02:27.340 --> 01:02:30.210 A:middle L:90% east is the building that is proposed and that actually 1075 01:02:30.219 --> 01:02:31.989 A:middle L:90% actually will be constructed. While the building to the 1076 01:02:31.989 --> 01:02:35.900 A:middle L:90% West is just a future development, which we only 1077 01:02:35.909 --> 01:02:38.760 A:middle L:90% designed for in our conceptual plan. Um this is 1078 01:02:38.760 --> 01:02:42.880 A:middle L:90% our actual site. Um this entire area is just 1079 01:02:42.880 --> 01:02:45.429 A:middle L:90% gonna be grass area for the future building. While 1080 01:02:45.429 --> 01:02:47.380 A:middle L:90% this will be our proposed building that will be constructed 1081 01:02:47.380 --> 01:02:51.190 A:middle L:90% , it's about 52,000 square feet. Um You can 1082 01:02:51.190 --> 01:02:52.440 A:middle L:90% see here traffic will be coming from the north and 1083 01:02:52.440 --> 01:02:55.159 A:middle L:90% wood and car traffic will just be coming into the 1084 01:02:55.170 --> 01:02:59.059 A:middle L:90% parking area where the front of the building will be 1085 01:02:59.059 --> 01:03:01.460 A:middle L:90% located while um traffic will be able to come into 1086 01:03:01.460 --> 01:03:05.309 A:middle L:90% our site access or access road into the loading base 1087 01:03:05.500 --> 01:03:07.699 A:middle L:90% . And you can see the water and sanitary lines 1088 01:03:07.699 --> 01:03:08.989 A:middle L:90% which run through the site and then the storm water 1089 01:03:08.989 --> 01:03:12.949 A:middle L:90% management on down at the bottom. We have about 1090 01:03:12.960 --> 01:03:16.619 A:middle L:90% 169 spaces shown on our in our concept. Or 1091 01:03:16.619 --> 01:03:20.929 A:middle L:90% are they out right now and there's only 131 required 1092 01:03:20.929 --> 01:03:23.800 A:middle L:90% parking spaces. Um so grating are greeting was relatively 1093 01:03:23.800 --> 01:03:27.849 A:middle L:90% easy, which is um maximum five slips, but 1094 01:03:27.849 --> 01:03:30.610 A:middle L:90% we actually had 8000 cubic yards difference and fill, 1095 01:03:30.610 --> 01:03:34.000 A:middle L:90% which is rather significant. And we understood that if 1096 01:03:34.000 --> 01:03:36.440 A:middle L:90% we just lowered the building pad by about one ft 1097 01:03:36.449 --> 01:03:39.630 A:middle L:90% than everything would be balanced out from that and just 1098 01:03:39.630 --> 01:03:42.940 A:middle L:90% from the roads as you can see, Um it's 1099 01:03:42.940 --> 01:03:45.429 A:middle L:90% just one longitudinal slits with typical cross sections. Um 1100 01:03:45.429 --> 01:03:50.500 A:middle L:90% So the roads were relatively easy to develop original sediment 1101 01:03:50.500 --> 01:03:53.500 A:middle L:90% control. We have uh to settlement basins on site 1102 01:03:53.510 --> 01:03:55.440 A:middle L:90% , one at the top and one at the bottom 1103 01:03:55.449 --> 01:03:59.829 A:middle L:90% , and these are separated into two drainage areas. 1104 01:03:59.829 --> 01:04:01.340 A:middle L:90% Look at just as you can see from this large 1105 01:04:01.349 --> 01:04:05.320 A:middle L:90% drainage divide across the middle. Um We have diversion 1106 01:04:05.320 --> 01:04:09.590 A:middle L:90% dykes to assist in those um and draining into the 1107 01:04:09.590 --> 01:04:12.239 A:middle L:90% sediment basin as you can see, and then silk 1108 01:04:12.239 --> 01:04:15.199 A:middle L:90% fence along the outside to keep all settlement onto the 1109 01:04:15.199 --> 01:04:16.800 A:middle L:90% site, as well as the construction entrance. Um 1110 01:04:16.809 --> 01:04:19.139 A:middle L:90% temporary seating as you can see is the only place 1111 01:04:19.139 --> 01:04:21.170 A:middle L:90% right here as that will be where the future building 1112 01:04:21.170 --> 01:04:24.280 A:middle L:90% is going to be. As well as the stockpile 1113 01:04:24.280 --> 01:04:27.519 A:middle L:90% area with a silk thin surrounding it um are face 1114 01:04:27.519 --> 01:04:32.349 A:middle L:90% to measures include um dominantly uh protection as we have 1115 01:04:32.360 --> 01:04:35.260 A:middle L:90% a rather large amount of inlets along Murray's road as 1116 01:04:35.260 --> 01:04:39.409 A:middle L:90% long as as well as around the parking areas, 1117 01:04:39.420 --> 01:04:41.860 A:middle L:90% so those will need to be protected to protect the 1118 01:04:41.860 --> 01:04:44.340 A:middle L:90% storm water system. And then permanent seating as you 1119 01:04:44.340 --> 01:04:45.469 A:middle L:90% can see, will be placed in the large grass 1120 01:04:45.469 --> 01:04:48.289 A:middle L:90% area where the future building will be placed as There 1121 01:04:48.300 --> 01:04:51.420 A:middle L:90% won't be any construction there after the initial grading of 1122 01:04:51.420 --> 01:04:55.460 A:middle L:90% the site. And also um the Phase one. 1123 01:04:55.739 --> 01:04:58.789 A:middle L:90% original settlement control sediment basin is the same as our 1124 01:04:58.789 --> 01:05:00.800 A:middle L:90% storm water managers upon which will just dredge out and 1125 01:05:00.809 --> 01:05:05.380 A:middle L:90% convert into a permanent stormwater management facility. I'll let 1126 01:05:05.389 --> 01:05:08.610 A:middle L:90% Aaron take it over next storm. Thanks both. 1127 01:05:08.989 --> 01:05:11.510 A:middle L:90% I'm going to cover the storm network and detention upon 1128 01:05:11.989 --> 01:05:14.789 A:middle L:90% . Uh Start with the pre and post development donations 1129 01:05:14.800 --> 01:05:18.050 A:middle L:90% . The redevelopment donations contain three watersheds. Uh The 1130 01:05:18.059 --> 01:05:21.000 A:middle L:90% watersheds roughly divide the site from north and south. 1131 01:05:21.010 --> 01:05:24.010 A:middle L:90% So we tried to uh all that with our grading 1132 01:05:24.019 --> 01:05:26.420 A:middle L:90% because you can see here in the blood picture uh 1133 01:05:26.489 --> 01:05:29.780 A:middle L:90% Those delineations are opposed developing delineations and we try to 1134 01:05:29.780 --> 01:05:30.780 A:middle L:90% get those to flow down to our new detention pond 1135 01:05:30.780 --> 01:05:33.340 A:middle L:90% at the bottom there and then on the bottom right 1136 01:05:33.340 --> 01:05:38.320 A:middle L:90% here is our Marie's road. Um Uh delineations, 1137 01:05:38.329 --> 01:05:41.809 A:middle L:90% they will flow into the Marines Road network and we 1138 01:05:41.809 --> 01:05:45.760 A:middle L:90% were we produced over 500 difference and run off between 1139 01:05:45.760 --> 01:05:48.119 A:middle L:90% our post and pre development. So I'll talk about 1140 01:05:48.119 --> 01:05:49.980 A:middle L:90% the storm network. Start with the inlets. We 1141 01:05:49.980 --> 01:05:54.039 A:middle L:90% have four main systems. Uh start with Marie's road 1142 01:05:54.050 --> 01:05:55.610 A:middle L:90% . A top right. We have great. And 1143 01:05:55.610 --> 01:05:58.380 A:middle L:90% what's that collect all the water from the north of 1144 01:05:58.380 --> 01:06:00.599 A:middle L:90% that and then uh, down here at the bottom 1145 01:06:00.610 --> 01:06:03.110 A:middle L:90% , bottom left, we have to sack curb and 1146 01:06:03.110 --> 01:06:05.900 A:middle L:90% let's uh collect the all the water at that point 1147 01:06:05.900 --> 01:06:08.849 A:middle L:90% there, as you can see right here. And 1148 01:06:08.849 --> 01:06:12.650 A:middle L:90% that's the plan view of memories right there. Next 1149 01:06:12.659 --> 01:06:15.159 A:middle L:90% , uh, system is the access road, which 1150 01:06:15.159 --> 01:06:18.539 A:middle L:90% we have split into two separate sides with a high 1151 01:06:18.539 --> 01:06:21.010 A:middle L:90% point in the middle of the road. The top 1152 01:06:21.010 --> 01:06:24.760 A:middle L:90% of the road will flow into the marine road network 1153 01:06:24.769 --> 01:06:27.550 A:middle L:90% up here into the sunlight and flow and to the 1154 01:06:27.550 --> 01:06:30.280 A:middle L:90% marines road. And then the bottom will flow down 1155 01:06:30.280 --> 01:06:31.929 A:middle L:90% into our southern parking lot, meat into these two 1156 01:06:31.929 --> 01:06:35.190 A:middle L:90% . And let's and flow into our detention on uh 1157 01:06:35.199 --> 01:06:38.369 A:middle L:90% Next is our loading bay area. We have two 1158 01:06:38.380 --> 01:06:40.960 A:middle L:90% great templates that are placed within the loading beds will 1159 01:06:40.960 --> 01:06:44.079 A:middle L:90% take about half the runoff from the building, the 1160 01:06:44.090 --> 01:06:45.340 A:middle L:90% loading bay and the grass area to the left of 1161 01:06:45.340 --> 01:06:48.590 A:middle L:90% their. Mhm. And then we also have the 1162 01:06:48.590 --> 01:06:51.780 A:middle L:90% eastern parking area, Which will we have to and 1163 01:06:51.780 --> 01:06:55.250 A:middle L:90% let's locate there at two low points. They will 1164 01:06:55.250 --> 01:06:57.989 A:middle L:90% flow to this, these two down here there the 1165 01:06:58.000 --> 01:07:00.880 A:middle L:90% southern parking lot again and they will collect at the 1166 01:07:00.889 --> 01:07:02.489 A:middle L:90% uh detention bond. And this is the nine and 1167 01:07:02.489 --> 01:07:04.760 A:middle L:90% 10. And let's again on the left side of 1168 01:07:04.760 --> 01:07:09.530 A:middle L:90% the southern parking. The horizontal pipe layouts. We 1169 01:07:09.530 --> 01:07:14.119 A:middle L:90% got the The touch upon pipe layouts right here. 1170 01:07:14.360 --> 01:07:15.300 A:middle L:90% You've got the nine and 10 down here again, 1171 01:07:15.309 --> 01:07:17.840 A:middle L:90% the wedding day in the middle and then the parking 1172 01:07:17.840 --> 01:07:19.940 A:middle L:90% area there on the right and then the Marie's right 1173 01:07:19.940 --> 01:07:24.210 A:middle L:90% again showing the sad curve and then they great inlets 1174 01:07:24.210 --> 01:07:27.480 A:middle L:90% up top and for pipe sizing, we went with 1175 01:07:28.280 --> 01:07:31.619 A:middle L:90% 15 pipes for all our pipes. We used the 1176 01:07:31.619 --> 01:07:34.800 A:middle L:90% rational method. The terminus only exception was the 12 1177 01:07:34.800 --> 01:07:38.679 A:middle L:90% pipe here between nine and 10. We had to 1178 01:07:38.690 --> 01:07:40.130 A:middle L:90% do that. We had to have that and live 1179 01:07:40.130 --> 01:07:45.360 A:middle L:90% there for prevent ponding at that island. So the 1180 01:07:45.360 --> 01:07:46.869 A:middle L:90% next thing, I'll talk about a vertical alignments. 1181 01:07:47.780 --> 01:07:51.159 A:middle L:90% Pretty much everything was normal except one constraint with our 1182 01:07:51.170 --> 01:07:55.960 A:middle L:90% loading base because they were so low compared to the 1183 01:07:55.969 --> 01:08:00.050 A:middle L:90% parking area to the right, The floating, We 1184 01:08:00.050 --> 01:08:03.349 A:middle L:90% had to drop the pipe network down to the detention 1185 01:08:03.349 --> 01:08:06.989 A:middle L:90% upon causing the bottom of the elevation of 2 98 1186 01:08:08.469 --> 01:08:12.030 A:middle L:90% 298ft compared to the starting point at three or 6 1187 01:08:12.030 --> 01:08:14.199 A:middle L:90% and retention pond you can see in the profile lower 1188 01:08:14.570 --> 01:08:18.180 A:middle L:90% jumps up and goes back down. Um, So 1189 01:08:18.180 --> 01:08:23.720 A:middle L:90% our detention pond, it was determined to be 18,000 1190 01:08:23.729 --> 01:08:26.380 A:middle L:90% cubic feet. You see the plan view here? 1191 01:08:26.390 --> 01:08:28.449 A:middle L:90% We got the three and let's come in and then 1192 01:08:28.449 --> 01:08:30.489 A:middle L:90% that's gonna be our allies coming out. You can 1193 01:08:30.489 --> 01:08:33.199 A:middle L:90% see this outlet flowing out here. We decided to 1194 01:08:33.199 --> 01:08:36.579 A:middle L:90% go with a dry pond and we were able to 1195 01:08:36.590 --> 01:08:42.180 A:middle L:90% meet the post development flows to meet pre development flow 1196 01:08:42.670 --> 01:08:45.159 A:middle L:90% . We're only constrained by east, which is only 1197 01:08:45.159 --> 01:08:47.050 A:middle L:90% a 10-foot easement. So the maximum pipe diameter that 1198 01:08:47.050 --> 01:08:50.319 A:middle L:90% we can use with 18". So, but we 1199 01:08:50.319 --> 01:08:53.750 A:middle L:90% were still able to meet that using the 18 outlet 1200 01:08:53.760 --> 01:08:56.899 A:middle L:90% pipe next we'll move on to that was what are 1201 01:08:56.899 --> 01:08:59.640 A:middle L:90% you doing next line here? Uh Like both said 1202 01:08:59.640 --> 01:09:01.590 A:middle L:90% before, I'm going to cover wet utilities very briefly 1203 01:09:01.600 --> 01:09:03.659 A:middle L:90% and the cost estimate and try to wrap everything else 1204 01:09:03.659 --> 01:09:06.279 A:middle L:90% as fast as I can to start off to review 1205 01:09:06.279 --> 01:09:09.869 A:middle L:90% the client goals. Um They need the water lines 1206 01:09:09.869 --> 01:09:12.350 A:middle L:90% loop from the northeast right of way of mary's road 1207 01:09:12.350 --> 01:09:14.279 A:middle L:90% , all the way down to the southwest of the 1208 01:09:14.770 --> 01:09:16.840 A:middle L:90% lot west of bars, sanitary line needs to connect 1209 01:09:16.840 --> 01:09:18.529 A:middle L:90% from the building down to the same area in the 1210 01:09:18.529 --> 01:09:23.319 A:middle L:90% southwest. The owner of the Jason properties allowed us 1211 01:09:23.319 --> 01:09:26.619 A:middle L:90% to throw in Eastman in their our design approach pretty 1212 01:09:26.619 --> 01:09:28.909 A:middle L:90% much followed the procedure of the land water engineering design 1213 01:09:28.909 --> 01:09:30.390 A:middle L:90% manual and all the other live in counties only requirements 1214 01:09:30.390 --> 01:09:34.399 A:middle L:90% , facility standards manual. Um Our plan view basically 1215 01:09:34.399 --> 01:09:36.270 A:middle L:90% , we started off at the top building connection at 1216 01:09:36.279 --> 01:09:39.430 A:middle L:90% the northern face of the building. We ran down 1217 01:09:39.430 --> 01:09:41.100 A:middle L:90% the center of the loading dock. So we didn't 1218 01:09:41.670 --> 01:09:43.369 A:middle L:90% Interfere with the future building is going to be on 1219 01:09:43.369 --> 01:09:44.960 A:middle L:90% the west side of the loading dock. We hugged 1220 01:09:44.970 --> 01:09:46.479 A:middle L:90% the southern border so we didn't interfere with any future 1221 01:09:46.479 --> 01:09:49.869 A:middle L:90% development and lot six fire hydrant flow. We were 1222 01:09:49.869 --> 01:09:55.220 A:middle L:90% able to fill latin counties requirements for that, which 1223 01:09:55.220 --> 01:09:58.590 A:middle L:90% is to hydrants Profile B. We kept between three 1224 01:09:58.590 --> 01:10:02.850 A:middle L:90% and 6 ft of cover pipe sizing. We follow 1225 01:10:02.850 --> 01:10:05.369 A:middle L:90% the same procedure that was in the engineering design manual 1226 01:10:05.670 --> 01:10:09.199 A:middle L:90% size or pipes using Bernoulli's equation realized that the doctor 1227 01:10:09.199 --> 01:10:13.159 A:middle L:90% iron pipe was best for the Water Saints A sewer 1228 01:10:13.170 --> 01:10:15.850 A:middle L:90% pretty much ran parallel to the water line. 12 1229 01:10:15.850 --> 01:10:20.529 A:middle L:90% ft separation kept over six ft of cover and minimize 1230 01:10:20.529 --> 01:10:24.539 A:middle L:90% their type slopes. Pipe sizing was done using the 1231 01:10:24.539 --> 01:10:27.279 A:middle L:90% engineering design manual stated before H. P. V 1232 01:10:27.390 --> 01:10:29.680 A:middle L:90% . C. Pipe was selected using manning's equation, 1233 01:10:30.260 --> 01:10:32.399 A:middle L:90% Cost analysis. Total cost was just over$2 million 1234 01:10:32.489 --> 01:10:36.869 A:middle L:90% . And just to recap, uh we followed all 1235 01:10:36.869 --> 01:10:39.840 A:middle L:90% the clients procedures. We not only did that, 1236 01:10:39.850 --> 01:10:42.560 A:middle L:90% we did so with the county requirements and we think 1237 01:10:42.560 --> 01:10:45.270 A:middle L:90% that we did an efficient and economically feasible design. 1238 01:10:45.390 --> 01:10:47.510 A:middle L:90% We'd like to thank you all for your time and 1239 01:10:47.520 --> 01:10:50.100 A:middle L:90% mentors, kevin, john and brian for all their 1240 01:10:50.100 --> 01:10:55.609 A:middle L:90% help. Does anyone have any questions? Why don't 1241 01:10:55.609 --> 01:10:58.920 A:middle L:90% you guys have to read the led lamps? Um 1242 01:10:58.930 --> 01:11:01.539 A:middle L:90% well we actually in our value engineering when we designed 1243 01:11:01.550 --> 01:11:04.000 A:middle L:90% for the second building we removed them because if they 1244 01:11:04.000 --> 01:11:06.270 A:middle L:90% were to develop the second building then they would have 1245 01:11:06.270 --> 01:11:11.000 A:middle L:90% to because the buildings themselves take about 25 of the 1246 01:11:11.000 --> 01:11:13.649 A:middle L:90% site. But in our value engineering we said if 1247 01:11:13.649 --> 01:11:15.979 A:middle L:90% you were to like if the client were to decide 1248 01:11:15.979 --> 01:11:17.520 A:middle L:90% not to build the second building then it would actually 1249 01:11:17.520 --> 01:11:21.659 A:middle L:90% save Like roughly 70 of wetlands. Which saves costs 1250 01:11:21.659 --> 01:11:25.369 A:middle L:90% about$30,000. So we put that in the value 1251 01:11:25.369 --> 01:11:28.560 A:middle L:90% engineering and um in the end to save some money 1252 01:11:28.560 --> 01:11:33.079 A:middle L:90% if they want to have that option. Billy Bush 1253 01:11:35.960 --> 01:11:46.569 A:middle L:90% . Yeah, looking at all. Thank you. 1254 01:11:47.060 --> 01:11:51.699 A:middle L:90% Uh huh. Alright. That concludes our final presentations 1255 01:11:51.699 --> 01:11:55.579 A:middle L:90% and I'd like to uh just offer a couple of 1256 01:11:55.579 --> 01:11:59.329 A:middle L:90% comments. Uh from my perspective, I'm extremely proud 1257 01:11:59.329 --> 01:12:03.210 A:middle L:90% of the students in my class, the presentations this 1258 01:12:03.210 --> 01:12:06.479 A:middle L:90% morning, we're very professional, very well done, 1259 01:12:06.479 --> 01:12:12.460 A:middle L:90% very practiced and quality of engineering done shown throughout the 1260 01:12:12.460 --> 01:12:15.060 A:middle L:90% last four months. It's very good. You guys 1261 01:12:15.069 --> 01:12:16.729 A:middle L:90% , we can tell you put a lot of hours 1262 01:12:16.729 --> 01:12:23.750 A:middle L:90% in my right. Is that is that an understatement 1263 01:12:23.760 --> 01:12:26.649 A:middle L:90% ? Um I think the mentors no. As well 1264 01:12:26.659 --> 01:12:29.979 A:middle L:90% . Um but what I'd like to have you guys 1265 01:12:29.979 --> 01:12:30.970 A:middle L:90% do is thank the mentors for all of your help 1266 01:12:30.970 --> 01:12:41.039 A:middle L:90% . Could you help me? They volunteer their time 1267 01:12:41.050 --> 01:12:44.579 A:middle L:90% and their expertise and uh probably put up with some 1268 01:12:44.579 --> 01:12:48.170 A:middle L:90% exasperation on your part during the semester at certain times 1269 01:12:49.149 --> 01:12:51.659 A:middle L:90% and handle it quite well, I'm sure, mm 1270 01:12:53.050 --> 01:12:54.640 A:middle L:90% . You know, it's tough. It's a learning 1271 01:12:54.640 --> 01:12:58.680 A:middle L:90% process that some of them have gone through in this 1272 01:12:58.680 --> 01:13:03.140 A:middle L:90% class and they know what it's like. So those 1273 01:13:03.140 --> 01:13:05.510 A:middle L:90% folks that didn't go through the class um, learned 1274 01:13:05.510 --> 01:13:09.029 A:middle L:90% it somewhere else and I'm sure found it just as 1275 01:13:09.029 --> 01:13:12.710 A:middle L:90% frustrating and it's it's not easy what you've just gone 1276 01:13:12.710 --> 01:13:15.869 A:middle L:90% through, but it certainly will help you in your 1277 01:13:15.880 --> 01:13:15.670 A:middle L:90% future career.
