120522_NineMileRun_Tree_13Several years ago, Swissvale Council approved a resolution establishing a Shade Tree Advisory Committee consisting of 3-5 resident volunteers appointed by Council. Since this resolution, the Committee has become inactive. Swissvale’s urban forest is not only an asset to the community, but also areas downstream of Swissvale, including the Nine Mile Run Watershed, Frick Park, and the Monongahela River. With the support of Borough Council, Nine Mile Run Watershed Association is assisting Swissvale in community outreach and reformation of this committee.

Based on 2010 data, tree canopy cover analyzed by the US Forest Service for Allegheny County found that approximately 39% of Swissvale’s land area is covered with tree canopy. That’s pretty good, but it can be better! There are many streets in Swissvale that could benefit from planting more street trees for shade, stormwater retention, and aesthetics. Maintaining trees for today while planting for tomorrow provides a connection for residents to the community now and in the future.

The Committee will advise the Swissvale Borough in managing the street trees of the urban forest by prioritizing maintenance, acquiring grants for tree plantings, assisting in community outreach, and drafting a tree ordinance. There are no minimum requirements for membership in the Committee. Swissvale seeks residents with a passion for their community and its trees as they relate to the preservation and expansion of the Borough’s stock of trees. Any and all members of the Swissvale community are encouraged to participate in the meetings and activities of the Committee.

If you are interested in volunteering for the Shade Tree Advisory Committee, you may contact Jared Manzo, Greenlinks Coordinator, at or 412-371-8779 x116 or Councilperson Darrell Rapp at or 412-271-7101.

Most of you are aware by now there is an issue of combined sewer overflows (CSOs) polluting Nine Mile Run. During wet weather, our watershed’s aging combined sewer systems do not have the capacity to handle both stormwater and sewage so they overflow into Nine Mile Run, introducing pathogens, trash, and other pollutants to the stream. We have actively worked to correct this issue through green stormwater infrastructure (GSI) interventions in the upper watershed over the last 14 years, including installing rain barrels and rain gardens and planting over 900 street trees.

Despite all of this effort, however, we still have degraded water quality during and after wet weather. When we developed our 2013-15 Strategic Plan there was one main goal: to reduce the flow of stormwater and sewage into Nine Mile Run.

RRRPWe understood to achieve this goal we would need to install GSI facilities capable of capturing large quantities of stormwater before it enters the combined sewer system. In 2014, we worked with Matt Graham of Landbase Systems to identify areas in the watershed that have high amounts of stormwater flowing into curb inlets and eventually overflowing into Nine Mile Run. Through detailed analysis, he identified an area in the Homewood neighborhood of Pittsburgh, which is actually outside of the watershed, but is part of the Nine Mile Run sewershed, that contributes over 25 million gallons of stormwater and sewerage overflow to the stream annually during wet weather events.

In case you aren’t familiar, a sewershed is simply a drainage area determined by the curbs, storm drains, pipes, and outfalls that all drain to a common outlet (e.g., Nine Mile Run). It doesn’t match perfectly with the Nine Mile Run watershed boundary because sewersheds often cross the boundaries of watersheds that existed before urbanization.

RRRP sitesThe Rosedale Runoff Reduction Project (RRRP) is a holistic sustainable stormwater project with the goal to remove all 25 million gallons of overflow entering the stream. We will achieve this by constructing 3 large GSI sites, 40 stormwater management tree pits, 200 Hydra rain containers, and 10 rain gardens.

In October 2014, we were awarded $150,000 from PA Department of Community and Economic Development (DCED) Commonwealth Financing Authority (CFA) Watershed Restoration and Protection Program to construct one of the GSI sites. And most recently in January, we received notification that we were awarded $236,175 from the PA Department of Environmental Protection (DEP) Growing Greener Program to construct a second site and install 200 Hydras. Both of these grant awards will allow us to implement the first phase of the RRRP, which proposes to remove 7 million gallons of annual runoff from the combined sewer system.

Stay tuned for proposed plans, details, schedule of implementation, and outreach events related to the RRRP!

We were pleased to have the opportunity yesterday to host Thomas Hylton for a tour of our urban forestry work, and some of the other green infrastructure projects we have completed in the watershed. Tom is a Pulitzer-Prize-winning journalist from Pottstown, PA, the founder of Trees. Inc, and the President of Save Our Lands, Save Our Towns. He was in Pittsburgh to present at a Post-Agenda session for Pittsburgh City Council on Sidewalk Materials, called by Councilwoman Deb Gross.

He shared with Council members the innovative work that has been done in Pottstown over the last 20 years to preserve the life of large, mature street trees by re-thinking how to handle tree & sidewalk conflicts. He challenged the idea that concrete is the ideal material for sidewalks, showing how even in the absence of trees, it is prone to cracking, and spalling, and before long panels become uneven, leading to tripping hazards. In many parts of the world asphalt is the standard material used for sidewalks, and it is much more friendly to trees because it is flexible. It is also easier and cheaper to repair when repairs are needed. It can be painted with slip-proof paint so the surface will stay cool in the summer – the product used to mark out bike lanes in cities around the world.

Pottstown is also experimenting with porous materials such as Flexi-Pave. Many of you know that

NMRWA completed the first installation of this material, made of recycled tires, gravel, and polyurethane, in Southwestern PA in 2011 on S. Trenton Ave. across the street from what is now Biddle’s Escape Coffee Shop. It can infiltrate a remarkable amount of water – only in the most severe storms is any runoff produced.

Right now porous materials like Flexi-Pave are considerably more expensive than concrete, because few people or municipalities are using them. If usage increased, the price would come down. However, asphalt is cheaper than concrete and clearly preferable for a variety of reasons.

Hopefully one day soon Pittsburgh can become as progressive as Pottstown and update its ordinance that currently requires sidewalks to be constructed of concrete. It would be great to see experimentation with a variety of solutions that benefit our urban forest infrastructure, which is becoming more important than ever as we begin to experience directly the effects of climate change.

Thanks to Tom Hylton for sharing his insights and experience with us!

Last Monday, January 19th, we held a special Stream Sweep in Frick Park. We were joined by students from Chatham University who, as part of a service day on Martin Luther King Jr. Day, chose to clean up Nine Mile Run. Each year, Chatham hosts a day of service, honoring MLK, where their staff and students can give their time to the community. Those at the university could choose one of 4 activities to participate in that day. About 20 people chose to help us. Monday morning, braving the cold, they set out to collect trash and debris from the stream. Starting at the soccer field, we split into two groups to cover more ground. The stream was definitely different than it is when we host our Spring and Fall Stream Sweeps. Without any foliage on the trees, the trash was abundant and apparent. Thanks to colder recent temperatures in Pittsburgh, parts of the ground around the Stream were still frozen and some of the trash was stuck in the ground! A few participants attempted to remove a sock that was buried and frozen in the ground without any luck.

The students from Chatham worked hard and collected enough trash to fill 30 bags! They were able to warm up afterward with some hot coffee and hot chocolate. As always, the group found some interesting things while cleaning up the stream. One participant found a rug while another found a small hub cap with a few other small car parts.

We greatly appreciate Chatham reaching out to us to work together on the Stream Sweep. We want to thank all of the students and staff members for working hard on a chilly day.

Be sure to stay tuned for all of our upcoming events to join us in the watershed sometime soon!

Did you know? There are 3 employees at NMRWA named Sara(h)! We don’t always know which one someone is talking to but we always have fun with it.

It can be a challenge sometimes to differentiate between Sara, Sara and Sarah or Sara P and Sarah P, so we thought we would help you out.

We created a little game to get to know the 3 Sara(h)s better. Each Sara(h) answered the same five questions about themselves. Below are the questions and the Sara(h)s’ answers. Read the question and think about which answer you most identify with. Keep track of your responses and at the bottom, you will find a key that will tell you which Sara(h) you most relate to. You can also see what the other two Sara(h)s answered to learn a little more about them. Okay, let’s get started!

1. What is your favorite restaurant in Pittsburgh?
A. Il Pizzaiolo
B. Spak Brothers
C. Mad Mex

2. What is your favorite book, TV show and movie?
A. A Walk Across America, Breaking Bad, and The Life Aquatic
