Stormwater Treatment <br /> Stormwater on the Riverfront Development site does not require detention due to the proximity of the <br /> Snohomish River, designated as a receiving body. The stormwater treatment proposed does meet the <br /> prescriptive requirements of the city at the two municipal park sites, with a passive water quality faclity <br /> at Lowell Riverfront Park that intercepts parking lot runoff, and an active collection and routing to the <br /> storm sewer system at the 3-Acre Park. Runoff from the trails between the two parks does not require <br /> and does not receive water quality treatment. <br /> Off-site surface water from pre-existing conditions will receive water quality improvement in. the <br /> Riverfront Development site in a constructed wetland planned for the South Wetland Complex. This <br /> project is currently in design, with grant monies provided by the Washington State Department of <br /> Ecology. Construction of the facility will be independently funded and scheduled, but will complement <br /> the public amenities work on Bigelow Creek, within Wetland D, and on the trail system i the immediate <br /> area. <br /> Stormwater from the retail/mixed-use and residential developments is managed within those private <br /> development envelopes, with outfalls and connection points coordinated with downstream facilities in <br /> the Public Amenities Master Plan. <br /> r 0-.1......7.7- r 40 - t*t-k"§ _ j 4, a <br /> "V u t Y S. <br /> cm.,...!:_;,,,,:;.:1.1..,..-":7 <br /> 3i#:_:ve4i.;i-r:;:,_tt15".il::::,,T' <br /> nt <br /> lac 1 y� . <br /> r -t <br /> �.*, a t ' <br /> '41 .., � ?' + .+yam St ',. ; -L•� <br /> y � ip L.�hi'r v., f <br /> v. a+ivy, s < .r•. _. <br /> . w <br /> iira <br /> t w W vt rs '" <br /> t ,,!'i <br /> I. .:„.:411.K,.S . ?
