Knights Way Storm Drainage Improvements
- Storm Drainage System
- $3.5 million for North Ridge Phase IV & V
- Stormwater Management (Lead)
- Brown and Caldwell, Inc.
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 Knights Way includes the replacement of the existing 48-inch reinforced concrete pipe culvert under Knights Way with a box culvert that is 5 feet high and 12 feet wide in the vicinity of 1321 Knights Way and 7812 Blackwing Court. The culvert will outlet at the back of the property at 7812 Blackwing Court. Project location is noted in an overall project location map for the Northern North Ridge set of stormwater projects.
The goal of the project is to reduce structural flooding. In addition, Knights Way will be provided with a 25-year level of service. This means that the street will not overtop with water in a storm event of a magnitude expected to be equal or exceed once on average in a 25-year period.
|Fall 2017||Phase IV and V design complete|
|Winter 2018||Permit requirements, easement acquisition, and coordination of private utility relocations complete|
|Summer 2018||Phase IV and V construction begins|
|Fall 2019||Phase IV and V construction complete|
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.
