Most of you are aware by now there is an issue of combined sewer overflows (CSOs) polluting Nine Mile Run. During wet weather, ourÂ watershed’s aging combined sewer systems do not have the capacity to handle both stormwater and sewageÂ 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 gardensÂ 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.
We 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 Diclofenac sodium cream price to identify areas in the watershed that have high amounts of stormwater flowingÂ 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 isÂ part ofÂ the Nine Mile Run sewershed,Â that contributesÂ 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.
The 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 Flector tissugel heparine prix, 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) Propranolol online order 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 Duloxetine hcl dr 60 mg cap coupon, and the President of Is propecia prescription only uk. 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 â 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 Biddleâs Escape Coffee Shop. It can infiltrate a remarkable amount of water â 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!
Happy Halloween! In the past week and a half, with the help of volunteers, NMRWA has cared for 80 trees in the watershed, getting them ready for winter.
LastÂ Thursday, October 23, NMRWA staff and volunteers began working to care forÂ more than 60Â trees around Turner Elementary and along Laketon Road in Wilkinsburgâs first ward. The 18Â young trees located around the playground and in the schoolâs front lawn were weeded and mulched, and special care was taken to avoid burying tree root flares with mulch, a phenomenonÂ called volcano mulching. Volcano mulching is, unfortunately, a common site in urban landscapes. Burying a treeâs root flare with mulch has the potential to introduce fungal infections to the trunk, encourage girdling roots, suffocate roots, and move water away from the root ball. All of these can be detrimental to a young trees establishment or long term health, so we are careful to instruct volunteers on proper mulching techniques.
The next day, weÂ worked with a group of Chatham University Environmental Studies students to continue weeding and mulching the trees along Laketon Road. The students worked assiduously to remove all weeds from each tree pit by pulling them out completely by the roots. Weeds have fine feeder roots that are close to the soil surface to grab water, minerals, and oxygen, as well asÂ deeper roots that can extendÂ into the same areas as tree roots, so removing weeds from the tree pits helps reduce the competition for valuable water and nutrients.
After finishing up on Laketon Road, on Tuesday,Â October 28, weÂ worked with volunteers on Edgewood Avenue in Swissvale to remove weeds and add mulch to nearly 20Â red maples that line the Busway. These trees are growing in a challenging area so yearly maintenance to improve the conditions for the trees is important. Mulching a treeâs root system helps control extreme soil temperatures, retain soil moisture, reduce soil compaction, andÂ promotes root growth which is essential to establishment. As a general rule, we like to make sure mulch is maintained at a three to four inch layer.
Thank you to all our wonderful volunteers, and to the Wilkinsburg Department of Public Works for donating extra wheelbarrows for us to use at these events! Buy prednisone in the ukÂ next Saturday, November 8th when we’ll be planting trees in Swissvale!
This pastÂ Saturday morning, in partnership with the Western Pennsylvania Conservancyâs TreeVitalize program, NMRWAÂ planted thirteen new street trees in Wilkinsburg and Regent Square.
Our wonderful volunteers enjoyed breakfast at the NMRWA office before the tree planting demonstration. Then they headed off to plant trees! The trees planted ranged in size from small understory trees, such as serviceberries which grow to about 20 feet tall, to a large London planetree, which can grow to 60 feet!
Even though these trees have now been successfully transplanted, their success is not guaranteed! Slowly trickling twenty gallons of water per week into the root ball during the growing season is important to the young treeâs establishment – the general rule is that it takesÂ one year per inch trunk diameter for the tree to become established. If drought conditions exist, even more water per week may be necessary to ensure survival. For trees planted during the fall like these, one heavy watering after the leaves fall off is sufficient for winter preparation.
After all thirteen trees were planted, volunteers enjoyed lunch back at the NMRWA office. Thank you to WPC staff and all our volunteers for helping us introduce new stormwater stewards to the watershed!
Earth Day was technically Tuesday, April 22nd, but NMRWA staff members were busy this past weekend with several Earth Day events happening throughout Pittsburgh…
Clean Rivers Campaignâs Earth Day 2014 Walking Tour
This walking tour of Millvale was the first in a series organized by the Online pharmacy degree in usa and Levitra rezeptfrei günstig kaufenÂ to highlight green infrastructure projects and opportunities throughout the region.
Millvale, PA has made great strides in incorporating green infrastructure into the borough.Â Located along the Allegheny River, Millvale is susceptible to flooding, particularly from Girty’s Run which flows through downtown. They suffered from a massive flood in 2004 which destroyed and damaged many homes and buildings.
Tired of sewage backing up in their basements and floods damaging their infrastructure, Millvale turned to green infrastructure to absorb the rainwater before it hits the sewer system.
The boroughâs rain barrels, rain gardens, urban farm, street trees and bioswales all help prevent flooding in town.Â The tour started at the Millvale Library, with Councilman Brian Wolovich explaining how their green efforts came about from community interest. From solar panels on the roof to rain barrels and a rain garden in the backyard, the library is the first for Millvale and is also extremely sustainable.
Other tour stops included a large urban farm, the Millvale community gardens, and a large rain garden. The tour ended with delicious pastries in town and some participants walked up to Mt. Alvernia where Sister Donna spoke about their bioswales. For more pictures, visit the Herbal clomid ukImitrex cheap online!
This was the first tour in a series of five, each in a different neighborhood. The series will continue in the Nine Mile Run watershed in late May. To learn more and to register for the tour, visit: Order flagyl 500mg online
Tree Care & Comcast Cares Day at Dickson School
Other NMRWA staff joined Comcast employees for a volunteer day at Dickson School in Swissvale. Over 30 Comcast employees joined students and parents of students from Dickson School to care for trees and a community garden on the schoolâs campus. As part of the Comcast Cares day, the attendees weeded and mulched trees, painted picnic tables, and weeded the community garden. NMRWA staff was on hand with tools and knowledge on how to properly care for the trees that were at the school.
The staff members then traveled to Washington and Noble Streets in Swissvale where they cared for street trees. Along with the borough and about six volunteers, staff members were able to care for trees throughout the downtown Swissvale area.
Mt. Lebanon Earth Day 2014
Priligy in uk staff & NMRWA Board Member Matt Wholey attended the Propecia prescription cost uk on Saturday in Main Park. The event was a great success with live music, lots of great vendors and about 200 people in attendance. Even a Tesla was on display!
You may remember that Stormworks recently unveiled its new rainÂ barrel – Levitra online ohne rezept. Attendees were very interested in this innovative design, which you can read more aboutÂ Can you buy zovirax cream over the counter. Staff also handed out packets filled with seeds from native rain garden plants!
As you can see, the weekend was a busy and productive one. Thanks to everyone who attended or helped out with these events this past weekend! We always enjoy seeing you out in the community and look forward to seeing you in the watershed soon.
