Green Infrastructure

Through green infrastructure projects, the DPU seeks to protect and improve the natural water cycle of Richmond, providing benefits to both the environment and our community.

Green Alleys

St. Christopher'S STREET AND CHURCH HILL Green Alley Project

PROJECT DESCRIPTION

To address citizen drainage concerns in residential neighborhoods around the city, DPU decided to implement green alley solutions near St. Christopher’s Street and 23rd Street (Church Hill). These green alleys were constructed using permeable interlocking concrete pavement for the surface, creating a cobblestone look. This surface allows runoff to collect in the reservoir stone underneath before reaching the underlying soils to reduce runoff and improve water quality, while also addressing the drainage concerns.  

TIMELINE

This project was completed in March of 2012.

COST

Funding for this program was made available through a National Fish and Wildlife Foundation grant. DPU partnered with the Virginia Department of Conservation and Recreation’s Green Capital Project. $211,000 in grant funds were matched by DCR’s $213,000.

12th Street Green Alley Project

PROJECT DESCRIPTION

The 12th Street green alley project retrofit the existing 12th Street alley surface with low impact development (LID) technologies. This included a permeable paver system and an underground infiltration trench and underdrain, providing stormwater runoff treatment and storage before it enters the city’s combined sewer system. Due to the alley's age, incline and amount of existing underground utilities (water, sewer, gas, private utilities, etc.), the 12th Street alley project was a challenge, but was also a demonstration of the potential for even greater green development in Richmond.

RAIN GARDENS

CHIMBORAZO SCHOOL RAIN GARDEN PROJECT

PROJECT DESCRIPTION

The rain garden at Chimborazo Elementary School is the Richmond Public Schools’ first rain garden. The garden was created as part of DPU Stormwater Utility's educational outreach program to educate students about stormwater, conservation and protecting our local environment. The rain garden is used as an educational tool for the students of Chimborazo Elementary and the surrounding community to demonstrate the capture and filtration of rainwater before it enters storm drains. 

TIMELINE

The rain garden was opened on May 15, 2012. 

COST

The rain garden at Chimborazo Elementary was installed as a part of a larger investment in green infrastructure at two Richmond Public School campuses. The total project cost was $550,000, which included the installation of two bioretention basins, six infiltration planters and an Americast Bacterra™ at the Chimborazo Elementary campus, and two bioretention basins at the Albert V. Norrell Annex campus.

Green RoofS

Wastewater Treatment Plant’s Green Roof

PROJECT DESCRIPTION

A permanent rooftop planting system containing live plants was installed on the 6,000-square-foot roof of the wastewater treatment plant's effluent filtration building as a part of the plant's upgrade. Green roofs are able to absorb up to 99% of each inch of rainfall, while also offering natural insulation and a longer average lifespan than traditional roofs.

TIMELINE

The wastewater treatment plant's green roof was completed in the fall of 2010.

COST

Approximate cost of this project was $80,000.
