The combined Stormworks and Landforce team.

Nine Mile Run Watershed Association has been planning and implementing the Rosedale Runoff Reduction Project (RRRP) for the last 3 years. The goal of RRRP is to remove 25 million gallons of (sewage-laden) water from Nine Mile Run every year, by focusing on a section of Homewood, East Hills & Penn Hills that overflows into the stream during rains.

One of the main projects carried out this year to contribute to that goal was at the Homewood North Family Investment Center, on the Housing Authority of City of Pittsburgh’s (HACP) property. StormWorks, with a number of partners, installed two rain gardens that contribute to the larger project goal by capturing over 35,000 gallons per year.

This project was a team effort. StormWorks provided the design and project management, PWSA funded the project, HACP team worked with us to ensure access to the site, and implementation was a StormWorks+Landforce undertaking. Landforce brought a team of dedicated land stewards who excavated the garden basins, ran piping from the downspout into the garden, planted and mulched. Their efforts were superb.

Successful neighborhood projects require plans and visions developed by community stakeholders. We are taking this approach to the Phase II RRRP Study, which will guide the next group of green stormwater infrastructure (GSI) investments in the project area.

Beginning back in August 2016, we started the planning process through a series of outreach methods. We continued to partner with Operation Better Block, East Tri-Borough Neighborhood Association, and Penn Hills Community Development Corporation to engage as many Homewood, East Hills, and Penn Hills residents as possible. Collaboratively, we hosted a public meeting on August 30th to gather input on areas within the RRRP boundaries are have localized flooding and extreme runoff during rain events.

We also conducted a survey of the neighborhoods, and received responses from 60 households experiencing issues with rain runoff either on their property or nearby their homes. Through a partnership with CUSP, we were able to post these results on their easily accessible web map. The map is intended to visualize and facilitate a conversation around those problem areas, and residents are encouraged to continue adding locations to the map.

Our engineering consultant, GHD, has spent the past few months analyzing the hydrologic runoff in the project area. This is a technical term that means they are finding the areas where we can capture the most stormwater runoff through GSI. We will pair this technical analysis with the public input to create a proposed map of new projects. This will be vetted with the community over the spring of 2017, as the investments should reflect the desire of the residents.

We are excited to continue working with the community on this project! Stay tuned for next steps and upcoming presentations on the Phase II RRRP Study. If you have any questions, please contact Mike Hiller at

As you may have noticed or heard, the Oakwood-Batavia site is complete!

We celebrated this major accomplishment with a ribbon cutting on November 10th along with guest of honor, Mayor Bill Peduto and all involved community leaders, residents, stakeholders, and partner organizations. Thanks to everyone that was able to make the event, it was a special day for our organization and the community. It was great to see everyone that supported and put so much effort towards this project come together and celebrate its completion.


Check out the video of the ribbon cutting ceremony below!

(Runtime: 24 minutes; actual ribbon cutting at 22:30)

Special thanks go to the General Contractor on the project, PJ Dick, and subcontractors, DeFinis Mechanical Contracting, and Dom DeMarco Construction, Inc. And to StormWorks and Operation Better Block Jr. Green Corps that were responsible for the landscaping of the project.

Final modeling numbers by the project engineers, Ethos Collaborative, estimate the site is able to capture between 700,000 to 1.5 million gallons annually with a total storage volume of 21,700 gallons. These figures will be verified with post-construction monitoring equipment provided by PWSA.

Across the street from this facility is the second series of stormwater tree pits installed as part of the RRRP. The design includes two linear pits with five total trees and native vegetation as ground cover. Due to the poor condition of the existing sidewalk, the installation includes a new sidewalk the entire length of the block. Penn Landscaping and Cement Work was the contractor on this project.

Stay tuned for future updates! If you have any questions, please contact Mike Hiller at

If you drove by Oakwood-Batavia the last couple weeks you would have noticed the contractor, PJ Dick, forming and pouring the concrete of the project. These forms were used to outline the curblines, sidewalks, sediment forebays, and bioswale walls. The above ground portion of the project has finally become visible as the concrete has been poured. PJ Dick is scheduled to wrap up all the concrete work and patch the asphalt this week, allowing StormWorks to come in and plant the trees and native vegetation next week. We will coordinate a ribbon cutting once this project is complete.

Once this project is complete, we will begin work across the street on Oakwood Street to plant 5 trees in a pair of linear stormwater pits. They are similar to the four trees planted on Rosedale Street and part of the larger collection of 40 stormwater tree pits we plan on installing as part of Phase I of the project.

We also received approval to begin construction on seven trees planted in a series of five stormwater pits on Frankstown Avenue in front of the Salvation Army.

Lastly, you may have attended a meeting for the Phase II Study we are conducting for the RRRP. We are currently wrapping up almost two months of outreach, which included a public meeting and survey to understand where there are stormwater issues in the project area. We will combine these personal responses with our engineering analysis to develop a roadmap for the next phase of the project. Results will be shared over the coming weeks.

Stay tuned for future updates! If you have any questions, please contact Mike Hiller at

It has been a busy month with the RRRP. Both large green stormwater infrastructure (GSI) sites, Oakwood-Batavia and Crescent Early Childhood Center (ECC) are headed towards completion.

We spent most of August giving multiple tours each week of the two construction sites. There was great turnout for each event, including neighborhood residents, engineers, partner organizations, City officials, and other stakeholders. All were interested in learning more about these projects and understanding challenges and opportunities when building GSI in the City.

Oakwood-Batavia has moved forward without general contractor PJ Dick encountering many issues with utilities underneath the surface. The brick catchbasins needed some masonry repair, but not total replacement. Duquesne Light did have to replace a utility pole on site though, due to a rotting wood base, which they were able to turn around rather quickly (much appreciated!) All excavation is complete, and the R-Tanks® were installed on the northside of Batavia Street. Next up is the concrete work (sidewalks, curbs, etc). StormWorks will plant the site in mid-September to finish the project.

JASE Construction Services has completed a majority of the project at the Crescent ECC. Rain gardens 1-5 have all been excavated, R-Tanks® installed, and rain garden soils contoured. StormWorks worked with Operation Better Block’s Junior Green Corps students to build a foot bridge between gardens 1 & 2 and install the plants in most of the gardens. A team effort with all of the NMRWA staff the week of August 8th allowed the garden portion of the project to be finished in time for an annual Back to School Fair held in the school parking lot. JASE still needs to complete the connection to the overflow pipe on the western end of the project, and construct the Tokay Street tree trench. This will be done as soon as the City approves the final design this fall.

Stay tuned for future construction updates and eventually ribbon cuttings! If you have any questions, please contact Mike Hiller at

Lots of progress has been made with the Rosedale Runoff Reduction Project (RRRP) in recent weeks. To start, we have updated our website so please check it out at  We will continue to add information to this site as projects move forward. This blog area will be used to provide regular updates on design, construction, outreach, and anything else happening on the project.

In other exciting news, both the Oakwood-Batavia and Crescent Early Childhood Center sites are under construction!

On June 27th, PJ Dick broke ground on the Oakwood & Batavia Streets intersection green stormwater infrastructure (GSI) project. Currently Batavia Street is fenced off to traffic between Oakwood Street and Tyson Alley. The portion of Oakwood Street where the installation will be is also fenced off.  The excavation on Oakwood and bending around to southern side of Batavia has been completed. Next up is to excavate the north side of Batavia. The project is expected to be complete by August 15th.

On July 14th, JASE Construction Services broke ground at Crescent ECC on the first phase of the project, a series of five rain gardens with R-Tanks® along the front of the campus.  The second phase, the tree trench along Tokay Street which delivers the runoff to the rain gardens, is still under review by the City of Pittsburgh Department of Public Works (DPW). JASE is currently unearthing pipes from the early turn of the century to connect the project to as an overflow.  Work on excavation of rain gardens 1 & 2 are also underway near the corner of Tokay and Bennett Streets. The project is expected to be complete by August 15th.
