b. Approximately one-half of this site appears to drain toward Silver Lake and one-half south toward the stream that drains Silver Lake. There does not appear to be adequate drainage facilities in either direction to accommodate the increased rate and volume of storm water runoff that will result from this proposal. Therefore, an off-site drainage analysis must be performed by the applicant to determine what off-site drainage improvements are needed to accommodate the increased runoff in a non -erodible, non -flooding manner. On-site detention in addition to the potential off-site improvements will be required for stormwater discharging to the south. For stormwater discharging to Silver Lake, a baffle type oil/water separator and approximately 200 feet of grass lined swale will be required in addition to retention of the wetland and potential off-site improvements. (SEPA Water Policies) c. Prior to the issuance of any permits, a detailed drainage plan must be reviewed and approved by the City. Drainage must be routed so that it does not run off onto adjacent properties. If possible, drainage should be handled in open swales. (SEPA Water Policies) d. A method must be established for oil collection for all the residents to prevent oil being drained into the stream and lake system. (SEPA Water Policies) 14. The Department of Ecology stated that these conditions are adequate to mitigate the impacts of the development. The Department of Wildlife has indicated that with one minor change, they feel the City has "touched all the bases" with these conditions. Both agencies state that they do not want to be involved in doing a drainage study as requested in the appeal. 15. The second item appealed by the Silver Lake Action Committee is that the City has not required a plan to preserve migration routes or preserve nesting habitat for birds. 16. Tom Lux contends that the City understated the wildlife issues. He states the proposed project would have an adverse impact on the area and ecological chains would be broken. Mr. Lux contends that the Department of Wildlife also understated this problem. The impact of all of the developments in the area from loss of many trees, the blacktopping of over 60 percent of the land, the influx of many people, the headlights, the glare of parking lot lights. and the constant noise will have an adverse effect on the wildlife. All of this may transform Silver Lake from the natural resource it is today to a dead sea. 17. The neighborhood residents have identified wildlife on the site including ducks, geese, pheasant grouse, crow, woodpeckers, coyote, racoon, possum and squirrels. -5-
