Silverdale Trails – Underground Detention System

Silverdale Trails Aerial 1 21 1100x825 - Silverdale Trails - Underground Detention SystemConcrete pouring recently commenced for the new underground stormwater detention vault at the Silverdale Trails retail development in Silverdale, Washington.

Utilizing two 61-meter concrete pumps, Apeland Concrete pumped approximately 1,000-yards of CalPortland concrete in under 10 hours to complete the vault’s entire slab and footing pour.  A task that would require roughly 100 ready-mix concrete trucks.

Larger than a football field, this underground detention system is being installed under the shopping center’s future parking lot on the eastern-central portion of the site.  It is designed to contain all of the stormwater runoff on the parking lot, and through the 1,000 gallon per minute filtration system, dissipate water into the earth opposed to being forced offsite in a storm event.

The Silverdale Trails is a 212,000 square foot shopping center situated on an approximate 18 acre site at Kitsap Mall Boulevard and Greaves Way.  The site sits against a natural backdrop of old growth timber and natural wetlands with views of Mt. Rainier and Puget Sound.
