Subdivision an w chart attach for Bakersfie the hydrology l route. This or Akers ted in It is nd ed eld y route 3 was used to calculate a time of concentration to a collecting point for the apartment complex and industrial lots on the west side of Akers Rd. This time of concentration (28 minutes) was then used to determine the rainfall intensity (0.95 in/hr) to be used to calculate the peak flow across Akers Rd. The formula used for this calculation was Q = CiA = i*(0.55*AreaResidential + 0.8*AreaIndustrial + 0.95*AreaPavement). Through this method it was determined that a peak of 15.97 cfs of storm water would flow through the storm drain pipes to be installed passing under Akers Rd. Runoff coefficients were determined using the Rational Method Urban Runoff Coefficients Detail (D‐2) in the City of Bakersfield Subdivision and Engineering Design Manual. A runoff coefficient of 0.95 was selected for pavements. Runoff coefficients of 0.80 and 0.55 were selected for the industrial lots and residential lots respectively. In accordance with the gutter flow chart attached with the hydrology calculations the Q that can be carried in a gutter with a 0.20% slope and a 6” water depth is 6.5 cfs. All Inlets have a flow below the 6.5 cfs; therefore, the proposed 6” curb and gutter are adequate to handle the 10 year flow. A hydraulic grade line was calculated for the critical drainage route as shown in the attached Hydraulic Grade Line Calculation. HGL control was established at the ½ water depth of the drainage basin. The HGL includes freeboard of a minimum 0.5’ at catch basins and manholes in accordance with City of Bakersfield Standards. Catch basins were sized in accordance with the nomograph for capacity of curb opening inlets included in the Catch Basin Sizing section. City Type “A” Catch Basin parameters were used to solve the nomograph. Inlet openings vary from 3.5 ft to 5 ft wide. Both Akers Apartments and Akers Industrial complex will drain to a shared basin located with the industrial complex. The required basin volume per our drainage study is 5.35 ac‐ft. At a 7.5 ft depth of water, the proposed basin will provide a volume of 6.01 ac‐ft. (See calculations below.)

This equa ates 5 DRAINAGE ROUTES Drainage Route 1 (DR1) starts in Area 21 and picks up water from areas 20‐17 before picking up additional water from Area 50 and 51. Storm water from Areas 13‐15 and Area 48 are also added to the line before additional water from Area 27 and Areas 43‐46 are added to the same line. DR1 continues its path towards the sump as it collects storm water from areas 16, 47, and 49. Storm waters from Areas 52, 12 and 11 are then added to the route before collecting waters from Areas 10 and 9. The final Area that is added to the route before it reaches the sump is Area 54.2. DR1 is the longest of the routes to the sump with 2010 ft of line from the start of the route to the junction where routes 1‐3 collect on the west side of Akers road before crossing Akers and reaching the sump. From this junction on the west side of Akers, there is an additional 430 ft before the water enters the sump, creating a total line length of 2430 ft. Being the longest drainage route, DR1 also has the pipe with the highest invert elevation at 364.32 ft. A hydraulic grade line (HGL) was calculated for this route, as it was deemed the critical route. The results of this analysis show that there are not any instances where we violate the minimum required freeboard of 0.5 ft. Starting with an elevation corresponding to the sump being half full, the HGL analysis showed a minimum freeboard of 1.59 ft along this line (Inlet 11). DR1 Includes pipes: 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 74, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 91, 102 DR1 includes inlets I09, I10, I11, I12, I13, I14, I15, I16, I17, I18, I19, I20, I21, I22, I23, I24, I25, I26, I27, I51, I52, I53, I54, I55, I56 DR1 includes junctions J05, J06, J07, J08, J09, J10, J11, J12, J13, J14, J27, J28, J29, J30, J32, J35, J39, J40 Drainage Route 2 (DR2) starts in Area 1 and picks up storm water from Areas 2‐8, followed by Area 54.1, before merging into DR1, which takes the storm water to the sump. DR2 is the second longest drainage route at 1630 ft to the junction at the west side of Akers. Adding in the final 430 ft to the sump brings the total length of the line to 2044 ft. Starting with an elevation corresponding to the sump being half full, the HGL analysis showed a minimum freeboard of 2.07 ft along this line (Inlet 7). DR2 includes pipes 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 74, 104, 96 DR2 includes inlets I01, I02, I03, I04, I05, I06, I07, I08, 57 DR2 includes junctions J01, J02, J03, J04, J39 Drainage Route 3 (DR3) starts in Area 22 and picks up storm water from Areas 23‐26 and 28. Storm waters from Areas 31‐34, and 38‐42 are added to the line before collecting additional water from Areas 35‐37. Area 30 is then added to the line before the final area’s water (Area 29) is added to this line. After collecting Area 29’s water, DR3 merges with DR1 before being taken to the sump. 6 DR3 is the third longest drainage route at 1241 ft from Area 23 to the junction on the west side of Akers. Adding in the additional 430 ft to the sump brings the total length of this line to 1655 ft. Starting with an elevation corresponding to the sump being half full, the HGL analysis showed a minimum freeboard of 2.67 ft along this line (Inlet 49). DR3 includes pipes 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 69, 66, 67, 68, 70, 71, 72, 73, 92 DR3 includes inlets I28, I29, I30, I31, I32, I33, I34, I35, I36, I37, I38, I39, I40, I41, I42, I43, I44, I45, I46, I47, I48, I49 DR3 includes junctions J15, J16, J17, J22, J18, J19, J20, J21, J23, J24, J25, J26 Drainage Route 4 (DR4) collects storm water from Areas 55 and 58 before heading to the sump. Starting with an elevation corresponding to the sump being half full, the HGL analysis showed a minimum freeboard of 4.59 ft along this line (Inlet 60). DR4 includes pipes 89, 90, 103 DR4 includes inlets I60, I59, I58 DR4 does not include any junctions. Drainage Route 5 (DR5) starts in Area 53, collects water from Areas 56 and 57 and then enters the sump. Starting with an elevation corresponding to the sump being half full, the HGL analysis showed a minimum freeboard of 4.88 ft along this line (Inlet 63). DR6 includes pipes 75, 88, 93, 94, 95, 97, 98, 99, 100, 101 DR6 includes inlets I50, I61, I62, I63, I64 DR6 includes junctions J31, J34, J36, J37, J38 SPECIAL NOTE The retention basin and storm drain system, with the exception of catch basins I50, I51, I56, and I57 which are to be installed on Akers Rd., shall be maintained privately. CONCLUSION A system of catch basins and pipes will carry runoff from Akers Apartment and Akers Industrial Complexes to a shared basin located within the Industrial Complex. This study shows that adequate drainage facilities can be provided for the property with the proposed drainage system and basins. FIGURES AAND CALCULATIONS Inte 7 ensity Graph Curb Cap 8 pacity Nomog graph 9 Si t e La y o u t Inlet C 10 Capacity Grapph 11 CATCH BASIN SIZING Per the City of Bakersfield Inlet Capacity chart found on the previous page, a standard 7” catch basin opening on an 8” curb (6” curb plus the additional 2” drop at the opening) can accommodate 1.6 cfs per linear foot of catch basin, totaling 5.6 cfs for a 3.5 ft catch basin. As can be seen in the chart below, only one of the catch basins on our site will have an equivalent cfs greater than the 5.6 cfs that the standard catch basin can carry. Increasing the length of this catch basin to 5 ft in length increases its capacity to 8 cfs, which is greater than the projected 7.43 cfs. With this one catch basin sized at 5 ft in length and all other catch basins at 3.5 ft in length, the catch basins on our site have all been designed to accommodate their respective projected flows. *Note: One catch basin was close to the flow limit, and was up‐sized to be conservative.

St a r t i n g fr o m th e be g i n n i n g of th e ro u t e , we calculated flows until we encountered intersecting flows. At this point, we fi g u r e d ou t wh i c h pi p e ha d th e hi g h e s t fl o w ra t e , an d th e n fi g u r e d wh i c h ar e a s fr o m th e ot h e r in t e r s e c t i n g pi p e s wo u l d co n t r i b u t e to th e fl o w s at th i s Tc . Fo r ex a m p l e , following DR1 from the beginning, we first see intersecting pipes between ar e a s 17 an d 50. Area 17 has a Tc of 22 minutes and a flow of 1.11 cfs. Areas 50 and 51 ha v e Tc ’ s of about 15 minutes and combined flows of 5.74 cfs. These areas dominate the fl o w of th e pipe, so we will use their Tc to figure out sizing and the HGL. With a Tc for this ar e a of 16 minutes, we are able to add 1 residential area (Area 17) to the pipe in order to ca l c u l a t e th e peak flow in the pipe (residential areas have a minimum Tc of 15 minutes). Ar e a 18 is tw o minutes away, so its flows are not added because they don’t reach the pipe un t i l 17 mi n u t e s . Rounding down the Tc of areas 50 and 51 to 15 minutes, makes the ca l c u l a t i o n s even more conservative.
