Two significant city construction projects are continuing to change the landscape around Mountlake Terrace.
City residents can’t escape noticing the huge pile of fill dirt forming on the site of the former city hall at 232nd Street Southwest and 58th Avenue West. The dirt is being excavated from a work site just north of the Mountlake Terrace Library where a new city stormwater treatment plant will be built.
Following completion of the $1 million project, some of the dirt will be used as fill at a city service road near the Recreation Pavilion at 52nd Avenue West. City officials have approved the dirt transfer plan, determining that moving dirt to the service road will have minimal impact on nearby Terrace Creek.
Once completed, the stormwater treatment plant will be covered with a new parking lot for the library. The entire project is expected to be completed this summer.
Construction also continues on a new decant facility next to the city’s operation facility at 6204-215th St. S.W. The $800,000 project, once completed, will be used to settle wet sediments collected during maintenance work on water, sewer and stormwater utility systems.
Work at the decant construction site will require some lane closures of 215th Street Southwest between 61st Place West and 66th Avenue West this week. The project is expected to be completed this spring.
