Wetland sites, storm water ponds precede widening project

BATTLE GROUND – Construction on several environmental sites gets under way this week to prepare State Route 502 for widening next year.

Crews with local contractor Tapani Underground Inc. will build four wetland mitigation sites and six storm water ponds near SR 502 between Interstate 5 and Battle Ground. This work is Stage 1 of the SR 502, Widening from I-5 to Battle Ground project.

“Building wetlands and ponds this year sets us up for success on the entire project,” said WSDOT project engineer Chris Tams. ”We’ll be able to focus on building new lanes and overhauling intersections when we start Stage 2 next year. It also means we’ll be able to treat runoff during construction, which saves taxpayers some money.”

Stage 2, set for construction in summer 2013, widens SR 502 to four lanes, installs median barrier and improves intersections at Northeast 29th, 50th, 72nd and 92nd avenues to help reduce the severity of collisions along the 50-mph corridor.

All of the environmental work crews will perform this summer will be near the SR 502 corridor, with the exception of one 33-acre mitigation site along Curtain Creek in north Vancouver’s Sunset Oaks area. Curtain Creek is in the same watershed as the SR 502 project.

Residents along SR 502 and near Sunset Oaks can expect excavation work and intermittent flagging for truck traffic. Construction on wetland sites and ponds is expected to be complete in spring 2013.

Nearly 14,000 drivers use SR 502 between I-5 and Battle Ground every day. In the next 20 years, that number is expected to reach 40,000.

The $88 million gas-tax funded SR 502, Widening from I-5 to Battle Ground project is scheduled for full completion in 2015.
