193803412_Anthem_Drainage_Memo_160708 Drainage Report Anthem on the Park Prepared for: Yosemite Holdings, INC Prepared by: Peter Allen July 8, 2016 Stantec Consulting Ltd. DRAINAGE REPORT July 8, 2016 ap v:\1938\active\193803412\design\stormwater\16-07-08 submittal\193803412_anthem_drainage_memo_160708.docx 1 A drainage analysis was completed for the proposed Anthem on the Park project located northwest of the intersection of Lake Lucy Road and Yosemite Ave in Chanhassen, Minnesota. The proposed development will included 12 single family home lots with a new roadway and utilities. The following is a summary of the stormwater analysis completed for this development. Summary of Site Drainage Existing Conditions Under the existing conditions, the 9.0 arce site, which has a total drainage area of approximately 13.5 acres, is divided by a natural ridge that cuts the site approximately in half. This divide is also the hydrologic boundary between Minnehaha Creek Watershed District (MCWD) to the north and Riley Purgatory Bluff Creek Watershed District (RPBCWD) to the south. The north half of the site drains to two existing wetlands. These wetlands are connected by an overland spillway. Approximately 4 acres from off-site land to the north drains to the north wetland. The south half of the site drains to an existing culvert that flows to the south across Lake Lucy Road. The site is primarily wooded with 3 single family homes located on the southern side of the site. Proposed Conditions Proposed conditions will include the construction of 12 single family homes, a new roadway, and new utilities. The general drainage patterns will remain with the northern portion of the site draining to the two wetlands and the southern portion of the site draining to a proposed biofiltration basin to the south. Runoff from the roadway will be treated by biofiltration basins. The majority of pervious surfaces of the site will be turf, with the northwest corner being kept as woods. An emergency outflow pipe will be placed at the south end of Wetland East to provide additional outflow capacity during storm events that exceed the 100-yr, 24-hr event. Design Criteria Criteria and assumptions made for this analysis: • Peak runoff rates not to increase for the 2-, 10-, and 100-yr, 24-hr storm events. • Rainfall depths using Atlas 14 Riley-Purgatory Bluff Creek Watershed District (RPBCWD) nested distribution. Rainfall Event Rainfall Depth (in) 2-yr 2.87 10-yr 4.27 100-yr 7.41 • Minimum time of concentration was assumed to be 6 minutes. • Water quality requirement must meet NURP criteria (90% Total Suspended Solids (TSS) removal and 60% Total Phosphorus (TP) removal) • Infiltration: Due to the presence of Hydrologic Soil Group (HSG) Type D soils, infiltration is not recommended for this site. Peak Rate Control The following table summarizes the peak flow rates for each drainage area for the 2, 10, and 100-yr, 24-hr storm events under existing and proposed conditions. Based on the analysis the DRAINAGE REPORT July 8, 2016 ap v:\1938\active\193803412\design\stormwater\16-07-08 submittal\193803412_anthem_drainage_memo_160708.docx 2 proposed stormwater management meets the City’s requirements for peak rate control. Refer to the attached drainage area map and HydroCAD output information for further details. Rate Control Summary Storm Event Existing Condition (cfs) Proposed Condition (cfs) 2-yr 5.0 1.8 10-yr 9.6 4.9 100-yr 15.4 15.0 Runoff Volume The city is requiring that runoff volumes flow south cannot increase under proposed conditions. To achieve this, the on-site drainage area flowing south has been decreased from 3.70 acres with a composite CN of 79 to 2.63 acres with a composite CN of 85. The attached Figure 3 and 4 show a breakdown of the drainage areas flowing south. Below is a summary of the total on-site runoff volumes flowing south. Refer to the attached HydroCAD output for further details. Runoff Volumes Flowing South Storm Event Existing (ac-ft) Proposed (ac-ft) 2-yr 0.337 0.324 10-yr 0.674 0.592 100-yr 1.530 1.237 To provide addition volume reduction, the draintile within Biofiltration Basin 3 will be elevated to the maximum extent practicable (0.24 ft for type D soils) based on the MN Stormwater Manual. This will provide an additional 360 ft3 (0.008 ac-ft) of volume reductions assuming a 40% voids ratio. Water Quality Since infiltration is not feasible on the site, NURP water quality standards (90% TSS removal and 60% TP removal) were met. To achieve these standards biofiltration basins will be utilized. The software modeling program P8 was used to perform the necessary water quality calculations. Drainage areas for each outfall included some portions from offsite areas and undisturbed on- site areas. These areas were included in the analysis, but sediment loadings were removed to appropriately analyze the land disturbance drainage. The default particle filtration rate in the P8 was modified to achieve similar removal rates to those in the Minnesota Stormwater Manual. Below is a detail summary of the removal rates for each feature. Biofiltration basins 1 and 2 will include iron-enhance sand to improve the TP removal rates. Biofiltration basin 4 shows a TP removal rate of over 60%, which is likely not the case since this basin will not have iron enhance sand. The TP removal rates of these basins were modified to achieve 44%.
