For the past two years, NMRWA has been working with the Pittsburgh Parks Conservancy (PPC) to increase the environmental stewardship capacity of our watershed community. Funding for this work was provided by a grant received from the National Fish and Wildlife Foundation’s Five Star and Urban Waters Restoration Program. Maybe you read about this in our Doxycycline price generics pharmacy?

Yesterday, as a part this program, NMRWA staff co-led a training workshop for Urban EcoStewards on streamflow monitoring in Nine Mile Run. Along with Sarah Lavin, a graduate student in the Paroxetina venda online, Sara Powell & Paul Yanulavich spent a sunny Sunday morning working with eight volunteers to measure streamflow and take cross-section measurements of the stream.

It is important for us to understand streamflow patterns and how the stream channel is changing in Nine Mile Run, both for continued restoration efforts in Frick Park (e.g., erosion remediation), and also so we can assess how well management efforts in the upper watershed (e.g., green stormwater infrastructure, rain barrels) are reducing excess stormwater flows into the stream.

Unfortunately, continuous monitoring of discharge (the volume of water flowing through the stream during a unit of time) is complex and expensive. Instead, since last summer, we have been working with Buy viagra 100mg online (UES) volunteers to help us collect data that will allow us to create something called a Imitrex generic cost.

This curve will allow us to ‘reconstruct’ a continuous discharge record – giving us a much better understanding of streamflow in Nine Mile Run!

So, at Sunday’s training, we demonstrated how UES volunteers can measure the stream’s velocity and cross-sectional area – two critical pieces to calculating discharge. We then used similar methods to measure the stream channel geometry.

The geometry of the channel is also important to understand, because storms can cause large volumes of water to surge rapidly through Nine Mile Run, changing the stream channel shape very quickly. These changes, whether they are due to erosion or damage to built rock features, put our restoration efforts at risk. Regular cross-section measurements will allow us to look at how the shape of the stream channel is changing over time, and to apply necessary management efforts as needed.

Thank you so much to all the Urban EcoStewards and interested volunteers for coming out on Sunday! We will be posting more photos from the day on Buy latanoprost 0.005, so make sure to check them out!

Chilly temperatures and several inches of snow did not hold back NMRWA staff and volunteers from a productive tree pruning workshop at Kelly Elementary School on Saturday March 7th. Volunteers from Bartlett Tree Expert’s McDonald office performed some much needed pruning on trees planted at Kelly School in 2012 and 2013.  These trees were planted as part of Rooted in Wilkinsburg:  500 Tree Initiative.

Volunteers were instructed in proper structural pruning which includes thinning for good branch spacing, low limb elevation and removing dead, damaged, or diseased branches.  Additionally, proper limb removal via the three-step cut and branch collar locating was discussed.  You can learn more about these tree pruning methods Is cetirizine available over the counter. Tools were provided and the team went to work.  An impressive 61 trees were pruned over the two hour session.  Coffee, hot cocoa and donuts were enjoyed in celebration of the volunteers’ efforts.

As these ‘Prednisolone acetate buy online trees continue to age, as well as other newly planted trees in the watershed, more tree pruning maintenance will be needed.  If you are interested in volunteer events such as this, please consider participating in the Tree Tender Class on March 21, 2015 at the Upper Environmental Charter School. You can register for the class Price of pioglitazone.

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 Where to get promethazine in canada 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) Fluconazole buy online usa 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!

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 Strattera online buy to join us in the watershed sometime soon!

On Saturday November 8, NMRWA held their final tree planting of 2014.  Eleven volunteers, together with NMRWA staff, worked to plant six trees.  Four of those trees were planted along Columbia Avenue in Swissvale. The other two were planted near the corner of Union Street and Lacrosse Street.  Among the six trees were hedge maple, katsura, hybrid elm and redbud species. In the past, Columbia Avenue was lined with many large London Plane trees. Many residents looked forward to this planting as a way to start reestablishing the tree canopy along Columbia.

Annual planting and stewardship of new and existing trees is essential to sustaining a constant tree canopy in an area.  Many tree experts abide by a 1:1 ratio of tree removals to tree replacement as a sustainable policy for maintaining canopy cover.  A 2:1 ratio of removals to replacements is a policy adopted to increase canopy cover.  Once all of the trees were installed, volunteers reconvened to enjoy hot soup and good conversation. Thank you to all the volunteers that helped make this event great.  Another thank you to Swissvale councilperson Julie Grose for allowing NMRWA staff to set up materials and snacks in her front yard.
