Drainage dilemma delays Delridge Skatepark construction

When you visit Delridge Community Center for the ReFRESH Southwest festival this Saturday (1-5 pm, another update later today), you might wonder what’s up with Delridge Skatepark construction on the northeast corner of the DCC grounds. Though fall completion was the hope just a few months ago, that won’t happen – project manager Kelly Davidson tells WSB that skatepark construction is now expected to start in late summer, which would mean completion early next year. She says issues with groundwater and drainage at the skatepark site have meant it’s taking longer to completing the documents needed to send the project out for bid, but they’re getting closer – she’s hoping a meeting with engineers tomorrow will settle the issue of how they’ll deal with drainage.

Pending approval by Seattle Public Utilities, Davidson says “over-excavating” is likely to be the solution — digging a bigger hole, and surrounding the project area with fill that drains better than the existing clay. (She says a project team member has described it as “surrounding it with a sponge.”) Otherwise, groundwater could back into the bowls during heavy rain, and that would be a safety risk. She says this won’t change the skatepark design (by West Seattle-based Grindline), and doesn’t expect the water work to put the project over-budget, as they have a “contingency” to deal with this kind of issue. “Everything else [regarding construction] is ready to go,” she says, while acknowledging they would have liked to have known more about the drainage/groundwater challenges sooner, but geotechnical engineers didn’t get involved until the project’s “additional funding” was available at the first of the year. Once construction begins, she says it’s likely to take around 80 working days – based on a five-day workweek, that would be four months – meaning the skatepark isn’t likely to be open before next year. (If you’re looking for Parks info about this online – Davidson says the project webpage should be updated sometime later today.)

    There’s been a pile of dirt in that area of the park for a week or so now. I’d hoped that it was the beginning of construction on the skatepark, but maybe it was part of the geotechnical work.

    Work on the new playfield is scheduled to start right around now (“Late May/Early June”). I’m watching for that eagerly!

      Thanks for mentioning that, Jay. Checking.

    The ground in that area is HORRIBLE. We lived 1/2 block away from the park for a few years and every winter we had standing water in our backyard.

    A somewhat unrelated park question – I had heard a rumor awhile back that the city was considering replacing the non-usable wading pool at Highland Park with a sprinkler park (which would be awesome). Any truth to that?

    I can’t believe this expensive project still has a green light amidst all the problems there are in our economy now.

    The above comment from a person who lives near the site also is a clear sign the construction bill will be even higher because of long-standing drainage problems in the area.

    Wow – I was -just- walking thru the grassy areas at Delridge and noticed how ‘marsh-like’ it was. Nobody noticed or pointed it out before plans for a large swimming-pool like structure were set?
    Plant a few cat-tails and add some frogs and you’d have a wetland!
    Will be an interesting challenge for the geotechnical engineers, I’m sure!

    “I can’t believe this expensive project still has a green light amidst all the problems there are in our economy now.”
    .
    I believe this is being financed by the Pro Parks levy, so the money is already allocated and it can’t legally be spent on anything else. Also construction means jobs. Isn’t that good for the economy?

    It’s actually more expensive to not build it. When we fail to provide our kids with safe, accessible and free options for positive recreation and interaction, we pay the cost in so many other ways.

    Thanks for reporting this WSB. This project is taking forever!

    While I seek a more detailed update on the playfield…one data point, the bid date was just last week, May 26th.

    We have a message out to the project manager to find out how that turned out and what the timetable looks like now….TR

Sorry, comment time is over.
