This project was just one part of a larger plan, which included the Fred Fletcher Park Water Garden and Wetland. Stabilization and enhancement of the stream banks helps in preventing further erosion and degradation of the stream, thereby reducing the amount of sediment released into the stream and restoring habitat and biological integrity of the stream.

Fire Station Rainwater Harvesting

Type: Water Quality Retrofit

Completed: 2010

Summary: The City of Raleigh's Stormwater Management Division has partnered with the City of Raleigh Fire Department to initiate a new effort to green several fire stations by installing rainwater harvesting systems and rain gardens. Cisterns will collect rainwater draining off existing rooftops at each facility so that it can be reused for outdoor water uses. The goal of this program is to replace this use of Wake County's drinking water supply with the harvested rainwater collected in the cisterns.

Five Points Drainage Improvements - Phase I & II

Type: Storm Drainage System

Completed: October 2015

Summary: The goal of this project is to reduce roadway flooding and stormwater over-topping the curb along Fairview Road. Improvements were separated into two phases.

The second phase involved improvements to the drainage system along Fairview Road and Myrtle Avenue.

Fred Fletcher Park Water Garden and Wetland

Type: Water Quality Retrofit

Completed: Fall 2009

Summary: The Fred Fletcher Park Water Garden and Wetland includes an aesthetically pleasing garden with a variety of evergreen and perennial plant species; a new ecosystem for butterflies, dragonflies, frogs, ducks and other animal species; naturally filtering stormwater that flows into the water garden to clean the runoff before flowing downstream into Pigeon House Branch; and serves as an educational opportunity for neighboring schools and park patrons on the new habitat and the functions of the water garden. The Water Garden and Wetland was the recipient of the Natural Resource Conservation Award from the 2010 Raleigh Environmental Awards.

Greystone Dam

Type: Dam Rehabilitation

Completed: May 2011

Grove Park Apartments

Completed project

Type: Property Acquisition/Flood Mitigation

Completed: September, 2014

Summary:The City received a grant award from the Federal Emergency Management Agency (FEMA) for acquisition and demolition of four multi-family structures at the Grove Park Apartment Complex on Noble Road.

Completed: Summer 2011

Summary: Construction of the improvements to the undersized drainage system along Harps Mill Road and Haymarket Lane was to serve as the major drainage system outfall for the northern drainage tributary of the North Ridge Community, more than 300 acres of land. A history of structural and street flooding events in the area resulted in improvements to the storm drainage system. The goal of the project was to reduce structural flooding and provide Harps Mill Road, Haymarket Lane and Ravenhurst Drive with a 10-year level of service. This means that the streets 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.

Type: Drainage System Upgrade

Completed: April 2014

Summary: Construction for new drainage infrastructure and existing undersized piping is complete, connecting previous upgrades from the Harps Mill Road, Haymarket Lane Phase I improvements to the new system along Haymarket Lane and upstream to Favorwood Court and bringing completion to stormwater improvements in this area. This project reduces street and structural flooding in 10 and 25-year storm events for properties along Ravenhurst Drive, Haymarket Lane, Favorwood Court and Harps Mill Road. As part of the Phase II and III improvements, new 96-inch piping, a 5x8 box culvert and 60-inch piping from Haymarket to Harps Mill Road were installed, along with associated yard drains, street catch basins and new sanitary sewer pipe replacement.

Pullen Road Green Street Demonstration

Type: Green Street (Water Quality Retrofit)

Completed: June 2012

Summary: The City of Raleigh's Stormwater Management Division and Urban Design Center partnered with North Carolina State University's Landscape Architecture Department to design and build a green street demonstration project within the right-of-way on Pullen Road, between North Carolina State University and Pullen Park. The design showcases a stormwater bioretention rain garden device installed within an existing no-parking zone on Pullen Road. Stormwater drainage will flow from the street into the stormwater device, filter through vegetation and soil and then drain out through a pipe connected to existing stormwater infrastructure located below Pullen Road.

Ravenwood Drive Culvert Replacement

Type:  Drainage System

Roanoke Park Neighborhood Drainage

Type:  Drainage System Upgrade

Completed: May 2011

Summary:  The Roanoke Park Neighborhood is one of the older neighborhoods in the city of Raleigh.  As with many of Raleigh's older neighborhoods, the existing storm drainage infrastructure was not adequate to meet current City of Raleigh standards.  The intersection of West Aycock Street and Dare Street had been particularly prone to flooding in intense rainfall events due to undersized catch basins and pipes. This project lessened the flooding at this intersection.

Simmons Branch Culvert Improvements Ph 1

Smallwood Park Stream Enhancement

Type: Stream Enhancement

Completed: Fall 2010

Summary: Impairment of the Smallwood Park Stream was the result of runoff from impervious surfaces associated with the urban development in the watershed, straightening, hardening and other man made modifications of the stream and pollution from years past as well as today. This project included the use of boulder structures along the stream bank and concrete structures within the stream channel, combined with a landscaping plan to permanently stabilize the stream and prevent further erosion.

Upper Longview Lake Preservation

Type: Lake System Improvements and Preservation

Completed:  December 2013

Summary:  Project focused on stabilization of the stream banks by reshaping them and using plants to reduce nutrients in the water.  Removal of sediment from the lake helping to improve the quality of the water.  Safety issues near the bleachers at the Enloe High School athletic field were also addressed by the installation of an engineered rock wall.

This project will mitigate historically flooded structures and restrict any new structures from being placed on the affected lots.

Yorkshire Downs Stormwater Drainage Improvements

Type: Drainage improvement

Completed: Summer, 2012

Summary: Located in the Crabtree Creek Watershed, it is one of the largest stormwater improvement projects that the Stormwater Management Division planned, designed, and constructed. A history of frequent structural and street flooding events along Yorgate Drive resulted in improvements that now have a 25-year level of service.
