Rainwood Lane Stormwater Improvements (North Ridge Phase V)
- Storm Drainage System
- Estimated $800,000
- Stormwater Management (Lead)
- Brown and Caldwell, Inc. (Engineering Consultant)
Formal design of improvements to the existing undersized storm drainage system is underway. Preliminary construction plans have been developed and will be revised as the design process continues. The team is also actively working with property owners who will be affected by the proposed construction improvements. The design plans are currently at the 65% stage.
Design includes the installation of a 48 and 54 inch reinforced concrete piping system in the vicinity of 1201 Rainwood Lane and a box culvert system 4 feet high and 4 feet wide near 1208 Rainwood Lane. The outlet of the box culvert system will be at the rear of the property at 1208 Rainwood Lane. This installation will be in addition to the existing storm drainage pipe in the street resulting in a parallel system with more capacity. The following is an overall project location map indicating the location of the Rainwood Lane project in relation to others. In addition to the stormwater system upgrades, sanitary sewer main replacements will occur to bring the sewer pipe up to City of Raleigh standards and to move portions of the main out of conflict with the stormwater system upgrades.
The goal of the project is to reduce the frequency of street and right of way flooding by providing a 10-year level of service for Rainwood Lane. This means that the street will not over-top in the storm event of a magnitude expected to be equaled or exceeded once on average in a 10-year period. in addition, the project will reduce significant private property yard and structural flooding.
|Early 2014||Final design and easement acquisition is anticipated|
|Late 2014||Construction anticipated to begin|
This project is one of several similar projects located along the northern tributary stream to the upper North Ridge Country Club Lake. It is located in the Perry Creek Watershed. A history of flooding events resulted in public meetings in April and June 2006. An engineering study was completed in December 2006. Street and structural flooding has occurred along this street and the engineering study recommended improvements to the existing storm drainage system.
