Current Activity

This project is part of the North Ridge Phase IV and V storm drainage improvement and stream stabilization project. The City's design consultant, Brown and Caldwell, Inc., is currently surveying sections of the North Ridge area for modeling and an as-built survey. Brown and Caldwell also is reviewing comments from the 65 percent plan review. The new data and comments will be incorporated into the 90 percent design plans. The project design and permit requirements are expected to be complete in the fall.


Project design for Upper Audubon Drive and Wagram Court includes the installation/replacement of a 24-inch reinforced concrete piping system in the vicinity of 7109 Laketree Drive and 7901/7905 Audubon Drive. A portion of the stormwater flow will be routed through a new 24-inch concrete pipe system along Wagram Court.

In addition, approximately 1200 LF of stream between Rainwood Lane and Knights Way and an additional 280 LF of stream downstream of Knights Way will be benched and stabilized to accommodate the streams 10-year storm event flows. Project location is noted in an overall project location map for the Northern North Ridge set of stormwater projects.

This project is one of several projects located along the northern tributary stream to the upper North Ridge Country Club Lake within the North Ridge community. It is located in the Perry Creek Watershed. A history of flooding events in the area resulted in public meetings in April and June 2006. An engineering study was completed in December 2006. Although there are no known structural flooding problems along the street the potential exists for the street to overtop with water. The engineering study recommended improvements to the existing undersized storm drainage system.
