A drainage pipe that discharges stormwater down the east side of the Parkview Point development needs repairs. As a precaution, Pierce County rerouted the stormwater run-off to the west side of the development to avoid contributing to the natural erosion that affects the slope.
On Feb. 20, 2019, Pierce County found the junction between two pipes was leaking after a local resident reported possible erosion underneath the drainage pipe.
Pierce County’s building official reviewed the site Feb. 21 to evaluate the safety of the occupied buildings nearest the slope. No life safety concerns are present.
Crews plugged the inlet and rerouted the stormwater run-off through an interim bypass to a county-owned stormwater pond several hundred feet west of the site on Feb. 22.
Crews installed a temporary bypass along 32nd Street Court Northwest in March and early April.
The bypass will direct stormwater from the intersection of 9th Avenue Court Northwest and 32nd Street Court Northwest to the county-owned stormwater pond at the end of 13th Avenue Northwest. Crews will be monitoring the water elevation in the pond throughout the rainy season.
Permanent pavement repairs were made on July 31 to replace the temporary pavement patch in the area of the drainage improvements.
