The stormwater conveyance system located at NE 157th Court cul-de-sac discharges runoff to an existing swale that is located in an easement that overlays several private residential lots. The stormwater swale is difficult to access due to private structures located in the vicinity. The City is interested in implementing an alternative stormwater system to reduce the need to maintain a facility outside of the right-of-way. The proposed design will remove the existing curb inlet catch basin, conveyance/perforated piping, and bioretention swale. The existing drywell will remain in place. The removed portions of the stormwater system will be replaced with: - Two Stormfilter Catchbasins (totaling 4 cartridges). - Four, 13-foot deep 48-inch diameter drywells connected in series via 12-inch perforateted pipe. - Backfill bioretention swale with select borrow/topsoil and hydroseeded with lawn.
