Flow Control System (Part D):
Based upon the City of Renton Drainage Manual, the following steps are required to determine the mitigation of storm water runoff of the developed project:
Full Dispersion – N/G (no good) – The property does not have adequate flow path lengths to allow for full dispersion; Full Infiltration – N/G – The soils have been classified by the Geotechnical Engineer as “fine loamy sands” with a low permeability rate; Alderwood Series soils w/ high ground water present. These soils are not adequate for full infiltration per the Drainage Manual. The Geotechnical Engineer does not recommend infiltration or retention of onsite runoff due to the high ground water table and poor draining soils. Limited Infiltration – N/G- With the presents of a high ground water table, the use of infiltration BMP’s is not recommended by the geotechnical Engineer or allowed by the City manual. Limited Dispersion – N/G – The soils, the high ground water table and the lack of available flow path do not allow for these types of BMP’s. Perforated Pipe Connection – This BMP will be used on the lots as each house connects to the onsite stormwater facility.
The project will be sized for a storm water facility (vault) to provide runoff control. The facility izing calculations can be found attached to this section.

and developed runoffs from the project. To meet the performance standard and allow for the bypass area to discharge, the storm water detention volume was calculated at 10,692 cubic feet. The proposed vault (within the active (detention) portion) is 509.30’ overflow – 504.90’ outlet (4.40’ active storage). The detention portion of the vault would be 108’ x 22.50’ (wide) x 4.40’ deep (detention) OR 10,692 cubic feet. The proposed vault is adequately sized for flow control for the proposed development.
