North Ridge Drainage Improvements

Phases IV and V

We're improving the stormwater system on Lower Audubon Drive, Knights Way, and Rainwood Lane. We'll be repairing streams, too. Work will reduce street, yard, and home flooding in the North Ridge community. 

Knights Way and Rainwood Lane are closed for construction. More details below.

Design

Here is the design for each section: 

Lower Audubon Drive

  • Replacing the 36-inch pipe under Audubon Drive with 42- and 54-inch pipes near 7708 Audubon Drive;
  • Installing double storm drains along Audubon Drive to increase the infrastructure's ability to handle stormwater flows; and, 
  • Replacing the drainage outlet on Audubon Drive and connecting it the neighborhood stream to prevent erosion.

Knights Way

  • Replacing the 48-inch pipe under Knights Way with a box culvert that is five feet high and 10 feet wide near 1321 Knights Way and 7812 Blackwing Court; and, 
  • Stormwater runoff will come out of the pipe near the back of the property at 7812 Blackwing Court. 

Rainwood Lane 

  • Installing 48- and 54-inch pipes near 1201 Rainwood Lane; 
  • Installing a 4-foot by 4-foot box culvert system near 1208 Rainwood Lane; 
  • Stormwater runoff will flow out of the storm drainage system near the back of the property at 1208 Rainwood Lane; and, 
  • The new culverts will be added to the stormwater drainage system that's already in place so that the entire system can handle more stormwater flows during a rain storm. 

Stream Stabilizations

  • Restoring about 1,200 feet of stream between Rainwood Lane and Knights Way; and,
  • Restoring an additional 280 feet of stream downstream of Knights Way to accommodate the streams 10-year storm event flows in the North Ridge community.

Construction

Project Area

Active construction is underway! Work is being done in this order: 

Location Improvements Timeframe
Knights Way Stormwater System March - May 2020
Rainwood Lane Stormwater System May - Oct. 2020
Rainwood Lane, Knights Way, and Wagram Court Stream  Oct. 2020 - Feb. 2021
Audubon Drive Stormwater System March - June 2021

Knights Way

Crews prepared the site for construction, surveyed the area, cleared trees, replaced a sanitary sewer, and installed a new box culvert on Knights Way. The box culvert is 160 feet long and will carry stormwater through the system.

Rainwood Lane

Crews are working on Rainwood Lane until October. They'll do utility relocations, stormwater system updates, and a stream restoration.

Road Closures

Knights Way is closed between Blackwing Court and Vauxhill Drive. Detour signs are rerouting traffic to Ravenhurst Drive and Haymarket Lane. Even though work is done on this road, it'll stay closed until November so the contractor can access equipment. This date may change. 

Rainwood Lane is closed. Work will be done between the intersection of Farmingwood Lane and Sapwood Court. Signs are rerouting traffic to Audubon Drive, Ravenhurst Drive, and Haymarket Lane. 

Work Hours

Monday - Friday from 7:30 a.m. to 5:30 p.m. There is no work on the weekend or holidays.

Other Work in the Area

The Public Utilities Department is doing a waterline replacement in this neighborhood at the same time as the stormwater project. More details are available online.

Improvements will provide a 10-year level of service - water will not flood over the road during a storm that has a one 1 in 10 chance of occurring each year.

Background

This project is located along a stream near North Ridge Country Club Lake in the Perry Creek Watershed. A public meeting was held in December 2006 after residents reported ongoing flooding issues. The engineering study recommended improvements to the undersized storm drainage system.

Phases one through three have been completed.
