This is placed to eliminate soil migration between the in-situ material and the embedment material while allowing water to infiltrate into the surrounding soil. The geotextile should surround the clean, crushed aggregate. The overlap of the geotextile should be accomplished as shown in Figure 10. 6.4 Types of Backfill Required Table 6, Figures 9 and Table 7 indicates the appropriate locations and types of backfill required for the installation of the chamber system. The material above the clean, crushed, angular backfill used to envelop the chambers (layer D) can be as specified by the engineer to provide adequate sub-base for the overlying structures. Minimum and maximum fill requirements are shown in Figures 9. Table 6 provides details on backfill and compaction requirements.Figure 10Proposed Infiltrator System Buildup - Base (NTS) SK290 Stage Storage Depth (in)Chamber Volume (cf)Cumulative Volume (cf)68Depth (in)Chamber Volume (cf)Cumulative Volume (cf)1 0 1.21 42 75.75 96.39 2 0 2.42 43 77.76 98.81 3 0 3.63 44 79.74 101.21 4 0 4.84 45 81.69 103.59 5 0 6.05 46 83.61 105.96 6 0 7.26 47 85.5 108.31 7 0 8.47 48 87.35 110.63 8 0 9.68 49 89.16 112.93 9 0 10.89 50 90.94 115.21 10 3.05 13.93 51 92.67 117.46 11 5.51 16.62 52 94.36 119.69 12 7.96 19.3 53 95.99 121.88 13 10.39 21.97 54 97.57 124.04 14 12.81 24.64 55 99.1 126.17 15 15.22 27.3 56 100.56 128.26 16 17.62 29.95 57 101.96 130.31 17 20.01 32.6 58 103.28 132.32 18 22.39 35.24 59 104.52 134.28 19 24.76 37.88 60 105.67 136.18 20 27.12 40.51 61 106.71 138.02 21 29.47 43.13 62 107.62 139.78 22 31.8 45.74 63 108.34 141.43 23 34.12 48.35 64 108.8 142.92 24 36.43 50.95 65 109.15 144.34 25 38.3 53.54 66 109.42 145.72 26 41.02 56.13 67 109.6 147.04 27 43.3 58.71 68 109.67 148.3 28 45.56 61.28 69 109.67 149.51 29 47.81 63.84 70 109.67 150.72 30 50.05 66.4 71 109.67 151.93 31 52.28 68.95 72 109.67 153.14 32 54.49 71.49 73 109.67 154.35 33 56.69 74.02 74 109.67 155.56 34 58.88 76.55 75 109.67 156.77 35 61.05 79.07 76 109.67 157.98 36 63.21 81.58 77 109.67 159.19 37 65.35 84.08 78 109.67 160.4 38 67.47 86.57 79 109.67 161.61 39 69.57 89.04 80 109.67 162.82 40 71.65 91.5 81 109.67 164.03 41 73.71 93.95 Table 6 Stone CoverStone BeddingLane Enterprises, Inc., 3905 Harzdale Drive, Suite 514 • Camp Hill, PA 17011 • P: 717.761.8175 • F: 717.761.5055 • lane-enterprises.com 10 5.1 Stage Storage In order for a hydrograph to be properly routed through any detention system, it is necessary to know the stage vs. storage parameters of the system. Table 3 below, shows the stage storage of a typical SK31 chamber installation with minimum bedding stone of 6". If a deeper bedding is required, then additional storage would be available in that stone base as well. A spreadsheet for determining the installed volume of a chamber system is available to facilitate the calculations required for routing the storm through the underground chamber system. The storage in the installed system assumes a 40% stone porosity. Table 4 below provides the same information for the SK75 chamber. Table 5 below provides the same information for the SK180 chamber, but starts with the minimum beedding of 9”. 5.0 Installed Storage Volumes for StormKeeper Chambers SK31 Stage Storage SK75 Stage Storage SK180 Stage Storage Depth (in)Chamber Volume (cf)Cumulative Volume (cf)68Depth (in)Chamber Volume (cf)Cumulative Volume (cf)0 0.00 0.00 34 79.47 105.28 1 0.00 1.69 35 82.14 108.58 2 0.00 3.39 36 84.74 111.83 3 0.00 5.08 37 87.28 115.05 4 0.00 6.78 38 89.76 118.23 5 0.00 8.47 39 92.16 121.37 6 0.00 10.16 40 94.50 124.47 7 0.00 11.86 41 96.75 127.51 8 0.00 13.55 42 98.93 130.51 9 0.00 15.25 43 101.01 133.45 10 3.55 19.07 44 103.00 136.34 11 7.06 22.87 45 104.87 139.16 12 10.55 26.66 46 106.63 141.91 13 14.01 30.43 47 108.25 144.58 14 17.45 34.19 48 109.71 147.15 15 20.85 37.92 49 110.98 149.60 16 24.23 41.64 50 112.01 151.91 17 27.58 45.35 51 112.63 153.98 18 30.90 49.03 52 113.08 155.94 19 34.19 52.70 53 113.39 157.82 20 37.45 56.35 54 113.57 159.63 21 40.68 59.99 55 113.57 161.32 22 43.89 63.61 56 113.57 163.01 23 47.06 67.20 57 113.57 164.71 24 50.19 70.77 58 113.57 166.40 25 53.30 74.33 59 113.57 168.10 26 56.37 77.87 60 113.57 169.79 27 59.41 81.39 61 113.57 171.49 28 62.40 84.88 62 113.57 173.18 29 65.37 88.35 63 113.57 174.87 30 68.29 91.80 64 113.57 176.57 31 71.16 95.21 65 113.57 178.26 32 73.98 98.60 66 113.57 179.96 33 76.75 101.96 Table 5Table 3 Depth (in)Chamber Volume (cf)Cumulative Volume (cf)68Depth (in)Chamber Volume (cf)Cumulative Volume (cf)00.000.002232.03 43.86 10.001.122333.69 45.98 20.002.242435.30 48.07 30.003.362536.85 50.12 40.004.482638.33 52.12 50.005.602739.74 54.09 60.006.722841.07 56.01 72.239.182942.31 57.87 84.4311.623043.45 59.68 96.6014.043144.46 61.40 108.7516.453245.32 63.04 1110.8718.843345.93 64.52 1212.9721.223446.23 65.83 1315.0323.583546.36 67.02 1417.0625.923646.36 68.14 1519.0728.253746.36 69.27 1621.0430.553846.36 70.38 1722.9732.833946.36 71.50 1824.8735.094046.36 72.62 1926.7237.324146.36 73.74 2028.5439.434246.36 74.86 2130.3141.71 Table 4Depth (in)Chamber Volume (cf)Cumulative Volume (cf)68Depth (in)Chamber Volume (cf)Cumulative Volume (cf)00.001511.40 18.70 10.000.791612.42 20.10 20.001.581713.34 21.45 30.002.371814.16 22.73 40.003.161914.83 23.92 50.003.952015.27 24.97 60.004.742115.50 25.91 71.416.3822 15.59 26.75 82.798.0023 15.59 27.54 94.149.6024 15.59 28.33 105.4511.1825 15.59 29.12 116.7212.7326 15.59 29.92 127.9614.2727 15.59 30.71 139.1615.7828 15.59 31.50 1410.3117.26Stone CoverStone CoverStone CoverStone BeddingStone BeddingStone BeddingProposed Infiltrator System - Supplied Volume at Given Depths Stormwater Calculations Existing Wall Footing Existing Masonry Veneer Wall Proposed Reinforced Concrete Rat Slab for Patio (4"D) Existing 4" Perforated Pipe Existing Drainage Stone Wrapped in Fabric Proposed Bluestone Patio atop Mud Setting Bed Cap Stone to Match Existing Walls Veneer Stone to Match Existing Walls #4 Vertical Rebar @ 18" OC #4 Horizontal Rebar @ 18" OC Washed 3/4" Crushed Stone Wrapped in Fabric 4" Perforated Drain Pipe Existing Soils Finished Grade Finished Grade 8"W Poured Concrete Wall Poured Concrete Footing 4'-0"1'-0"1'-2" 1.5% Pitch Proposed Masonry Wall & Walkway (Scale: 1/4" = 1') 2 2.7.24 Rev 1 - StormwaterMRD 2 4.15.24 Rev 2 - Stormwater, DetailMRD
