KNECHTS APARTMENT DRAINAGE STUDY May 17, 2021 SITE CHARACTERISTICS The subject property is identified on County Assessor's Maps as 17-02-31-31 Tax Lot 2200. It is located on the south end 34th Sl and east of 33d at.. The site is an open field and consists of about 2.0 acres. EXISTING HYDROLOGY The site is relatively flat and the site drain into the existing 340 St PROPOSED HYDROLOGY The proposed drainage system consists of piping the proposed impervious drainage to two detention ponds. East Basin The east basin collects the drainage from the buildings, parking spaces and walks on the east and south side of 34th Sl. and pipes the runoff to the east detention pond. The detention pond was sized using the TR -55 unit hydrograph storage indication method. The proposed outlet will drain into the existing storm drain in 340 St The total existing flow from the site is 0.73 c.f.s. The total proposed flow from the detention pond will be reduced to 0.63 c.f.s. South Basin The west basin collects the drainage from the buildings, parking spaces and walks on the west and north side of 34th Sl. and pipes the runoff to the west detention pond. The detention pond was sized using the TR -55 unit hydrograph storage indication method. The proposed outlet will drain into the existing adjacent ditch. The total existing flow from the site is 0.15 c.f.s. The total proposed flow from the detention pond will be reduced to 0.14 c.f.s. Attached are the following for each drainage basin: 1. Pre -Development 10 -year flow (TR -55) 2. Post -Development 10 -year flow (TR -55) 3. Routed Post -Development 10 -year Flow (TR -55) 4. Stage -Discharge Curve 5. Stage -Storage Curve 6. Hydrograph of 10 -year Pre -development 10 -year Post -Development and 10 -year Routed Storm CONCLUSION Based on my calculations and the proposed drainage system is sized properly and will provide the necessary flow control.
