Improvements to bring this two-mile-long section of hillside road to Municipality of Anchorage collector standards and provide a safer road corridor involved engineering investigations, public involvement, permitting, utility coordination, surveying and mapping, transportation planning, and multiple stream-crossing designs. Also included were extensive drainage improvements and entire road surface pavement overlay.

CRW evaluated the condition of the Wonder Park Subdivision utilities and provided design documents to replace 2,600 feet of severely corroded water mains with PVC pipe, including all fire hydrants and water services. The water mains were located within the streets and required the removal and replacement of existing roadway improvements.

CRW worked with the Municipality of Anchorage to upgrade this 4,000-foot-long, neighborhood collector roadway located in west Anchorage. The project overcame challenges including narrow right-of-way, limited parking areas and sight distances, a Fish Creek stream crossing, nearby vegetation, and conflicting utilities. A larger culvert was also installed to better accommodate fish passage.

Improvements to bring this two-mile-long section of hillside road to Municipality of Anchorage collector standards and provide a safer road corridor involved engineering investigations, public involvement, permitting, utility coordination, surveying and mapping, transportation planning, and multiple stream crossing designs. Hydraulic modeling to solve drainage problems involved the analysis of a contributing drainage area of 4,079 acres.

Two existing 78-inch-diameter corrugated metal pipe culverts that conveyed fish passage of Chester Creek beneath Providence Drive were replaced with a precast open-bottomed concrete pipe arch. Storm drain systems on either side of the creek were improved and utilities were supported and worked around. Construction also involved a temporary diversion of the creek.

Rehabilitation of this mile-long section of trail to improve safety and connectivity included replacement of four pedestrian bridges, installation of flood plain boardwalks, construction of a large retaining wall, and upgrades to the illumination system. A flood elevation model of the creek channel was created to determine flood water elevations. A drainage analysis was conducted on the surrounding 1,547 acres of contributing area.
