�..� all newly paved surfaces and ali existing Lake Park Apartmenis' surfa�es that drain to the location of the facilities must be provided. Due to the developed nature of this site, in the design of these racilities, a 6 month, 7_q nour stortn may be used to estimate runoff from aircady develoF�ed surfaces, instead o�the 2 year, 24-hour design storm required for newly devE��ped surfaces. (SEPA Water and Plant and Animal Policies) 6. The curr�;nt pian proposes to utilize an existing pond area on the adjacent site to the northeasi for the location of required stormwater facilities for the Lake Park Apartments' expansion. The existing pond was designed as a wetporiC with a vegetated swale at the outlet o`the pond. The new wetpond must contain live <�nd dead storage volumes equal - to the design volumes needed to sdtisfy City standards i.�r treatment of runoff from the Lake Park Apartments site. The vec.:tated swale must be reconstructed, if necessary, to treat runcff from all contributing surfaces according to current City standards. (SEPA Water and Plant and Animal Policies) 7. TY:s parkin� areas under thE buildings must be hydrologically isolated from the uncovered portion of the site. Runoff collected from covered parkina areas must dische�ge to the sanitary sewer. (SEPA Water Policies) P. A specially designated area will be required for washing of cars by tanants of the complex. The area must be hydrologically isolated from the rest of the site, be covered, and wash water from tne area rnust drain to the sanitary sewer after being routed through a baffl�•±ype oil/water separator designed to city standards. Signs must be posted on che site limitinr car washing to the designated area only. The tenant lease or rental agreement must contain a clause prohibiting car washing on the site outsids of the specially designated area. A covenant must be recorded and signed by the owner stating that such a clause will be written into the tenant lease and rental agreements. In addition, a note stating that car washing is only permissible in the designated area must be included on the storm drainage plans. As an aliernaiive to the specially designated car washing area, hose bibs can be eliminated from the site or tenant access to tham prevented. If this option is exercised, the tenant lease or rentaf agreement must contain a clause prohibiting car washing on the site. A covenant must be recorded and signed by the owner stating that such a clause will be written into the tenant leases and/or rental agreements. In addition, a note stating that car washing ;s prohibited on the site must be added on the storm drainage plans. 9. The tenant lease or rental agreement for the project must contain a clause prohibiting vehicle maintenance on the s+te. A covenant must be recorded and signed by the owner stating that such a clause will be written into the tenant leases andlor rental agreements. 10. Ali storm drains in the complex must be stenciled with substantiaily the foliowing language: "Dump No Waste, Drains to Wetland." This reminder is typically spray- painted onto the ground adjacent to the catch basin with the use of a stencil. The treatment needs to be repeated, approxirnately annually, when the paint wears off. The developer/owner;:iey either perform the stenciling, or give permission for volunteer groups to enter onto the property and perform the stenciling. The lead agency for this proposal has determined that it does not have a probable significant adverse impact on the environment. An Environmental Impact Statement is not required under RCW 43.21C.030(2)(c). This determination assumes cornpliance with state law and City :
