West Seattle’s only city-owned outdoor swimming facility, Colman Pool, is getting ready for its short, sweet summer season, opening on Memorial Day weekend as usual. But first, Seattle Parks has a project that will affect people who use the park, particularly along its waterfront walking/running/bicycling trail. According to Parks’ Garrett Farrell, a large vault will be installed to “hold backwash water from the sand filters” (remember, Colman Pool uses filtered Puget Sound water). Since the contractor has to bring in equipment (including a crane) as well as the vault – in pieces – while hauling out dirt from the hole they need to dig, “park users should expect a lot of traffic on the path between Fauntleroy and the pool.” Farrell says this all starts Monday, north of the pool (the path on the building’s east side will be blocked, as will access to the outdoor women’s restroom) and will be done before the pool’s scheduled opening on May 28th (here’s the brochure with this year’s full schedule).
