Project Update:
The Contractor is nearing the completion of the major construction activities for Stage 3 of the NW 57th Avenue Improvements. Remaining driveways are being constructed and the on-site Engineer will notify each resident or property owner when each driveway has been approved for vehicle traffic. 

After the completion of the driveways and roadway opening, the Contractor will be working to stabilize the site for the winter months. Initial grading, mulching, and general clean-up will be completed to minimize issues that can occur with the cold weather, snow, and the spring melt. Once the site has been sufficiently stabilized, the Contractor will move off-site until work resumes in the spring. Click here (PDF) to read the residents letter. 

Project Description: Reconstruction of NW 57th Avenue from Merle Hay Road to NW Beaver Drive. Project includes roadway improvements based on the Public Engagement Process, storm sewer construction, sanitary sewer installation, and water main replacement.

Project Status: 
As of Wednesday, Sept. 13, all underground utilities (water main, sanitary and storm sewer) between Merle Hay Road and NW 54th Court have been completed. The contractor plans on doing sub-grade prep for this area the weekend of Sept. 16-17, with a planned paving date of this coming Tuesday, Sept. 19.

While paving prep takes place to the west, the underground crews will continue to work east. Starting some time this afternoon, they will close NW 57th to through traffic west of NW 52nd Street. Underground work will take place from from the corner of NW 54th Ct to roughly 5250 NW 57th Ave. This work is expected to take several weeks, with a tentative paving date for that phase slated for the 3rd week in October.

Project Area

East of Merle Hay Road is the area between Merle Hay Road, Beaver Drive, Johnston Drive and NW 62nd Avenue. Here is a link to the Project Area Map. Neighborhood areas include NW 55th Avenue, NW 57th Avenue, NW 54th Court, NW 60th Avenue, & NW 61st Place. A map is available to identify which sub-group to which a neighborhood belongs.
Below are before and after pictures that have been prepared based on input from residents in the area during the above public workshops.

Visual Preference Survey

The visual preference survey was an exercise where the residents were asked to rate a series of images on a scale of -5 to +5 as to their opinion of how well a particular infrastructure improvement would fit in with their neighborhood. The improvements were grouped by category and the results are presented by neighborhood subarea average and the total neighborhood average. The most positive image in each category is highlighted in yellow, while the most negative image is highlighted in red. This purpose of the exercise was to begin the process of visualizing potential physical neighborhood improvements and to discuss the merit of various improvement alternatives. The results are not intended to be interpreted as definitive chosen alternatives.
