. �. � MEMORANDUM r� Y � o � TO: Kirk Brooks � FROM: Jane Zimmerman 1 S I��G . lo � DATE. October 9, 1996 SUBJECT: Pre-Application Meeting, 5929 Evergreen Way My commenu on the subject project ar;,: On-site detenti�n of stormwater runoff is required per City standards. Treatment of stormwater runoff from paved areas must occur, per City standards,prior to discharge of the stormwater from the site or to a stream or wetland. Stormwater detention/retention, quality protection, and treatment requirements for this project shall be those requirements in effect at the time of application for Public Works permits. Stormwater treatment is currently required when 10,000 square feet of pavement is created by a project and three options for stormwater treatment aze presented in the current City standazds. The least preferred option is allowed only if the first two options are infeasible in the opinion of the Public Works DeparUnent. The options for stormwater treahnent aze, in order of preference: 1) an infiltration basin designed and constructed acwrding to City standards, if suitable soils exist on the site. 2) a wetpond designed and constructed to City standards. 3) a baffle-rype oil/water separator followed by a vegetated swale, both designed and constructed according to City standazds. � Due to the developed nature of this site, an infiltration basin will probably not be feasible due to past compaction of soils. Therefore, a wetpond designed and constructed in accordance with City standards will be required if the amount of new pavement is 10,000 square feet or more. g:ldau\janelword�pa5929ew
