Better Bikeways, Better Watersheds: Big Plans for Schenley Park

Standing in a semicircle of maps and renderings of Schenley Park and surrounding streets, Mayor Peduto, Bike Pittsburgh‘s Scott Bricker, and the Department of Public Works’ Patrick Hassett recently announced exciting and progressive plans for protected bike lanes in Pittsburgh.

Peduto, Bricker, and Hasset share the mic at the press conference.

The first of the three segments of this project that we’re particularly thrilled to see will run from Schenley Plaza, snake along Schenley Drive and Panther Hollow Road, and end at Anderson Playground. Partitioned with bollards and marked with paint, the new bike lanes make it so that “families can bike with their kids, older folks can bike all over the city, to get to life, to connect kids to their schools and people to work and grocery stores and places of entertainment,” as Bricker said in the press conference.

BIkers came out in support of the new lanes.

“Schenley Park is our backyard,” one family told us at the event. Living so close to Anderson Playground, they’re enthused to see the new lane help them get from A to B in a way that’s safe for their entire clan. The new, protected bike lane (the first in Pittsburgh!) is slated to begin this month, and all three sections will be completed by Labor Day.

Schenley Park, further down the road

These infrastructure upgrades in the park are only just the beginning. Mayor Peduto in his announcement of these soon-to-be upgrades touched on his administration’s attentiveness to improve not only transportation infrastructure, but also stormwater infrastructure — often at the same time.

The Parks Conservancy’s work in the Panther Hollow Watershed is the quintessential opportunity to merge stormwater and transportation improvements.

Schenley Drive creates a number of challenges in the Panther Hollow Watershed:

  • Winding through the upper sections of the watershed, it makes up a large part of the impervious surface of Phipps Run. This generates a large amount of runoff every time it rains, leading to erosion.
  • The too-wide roadway does not serve pedestrians, bicyclists, or golfers well.
  • Grassy golf turf traditionally require intense mowing regimes, fertilizers, and herbicides, which eventually harm the watershed.

Recommended in the Panther Hollow Restoration Plan is a two-birds-with-one-stone kind of solution:

“Create a “complete street” that welcomes people, mitigates stormwater runoff, increases baseflow and improves water quality. Infiltration Berms capture runoff generated by the compacted golf course lawn, allowing for increased infiltration that can support a natural meadow within “rough” areas. Vegetated Swales slow down remaining runoff. The street will be narrowed and a separate path created for pedestrians and bicyclists. This path could be porous asphalt and will include an infiltration bed to capture and infiltrate the runoff in the upper portions of the watershed. Where infiltration is not feasible in the lower portions of the watershed, the stormwater bed will slow the movement of runoff for slow release of treated water to Phipps Run.”

All in all, this comprehensive approach addresses stormwater issues (at least 70,000 bathtubs of water per year would be taken out of our overloaded combined sewer system!) while making the road more usable for everyone.

Before that happens, though, we’re working hard on other points of the Panther Hollow plan. Currently, the new meadow on Bartlett and Beacon Streets is being seeded and will be full-grown later this summer.

Stay tuned as these restoration projects progress, and be sure to take a spin on the new protected bike lanes when they’re installed.

Who’ll Stop the Rain: Green Infrastructure in Schenley Park

Big, green things are in the works in Schenley Park and the Panther Hollow Watershed.

If you’ve been near Bartlett Playground in Schenley Park lately, you might have seen some of our progress on a nearby hillside, which right now looks a little like

Soon, though, the area will look something like

Is that the Cathedral of Learning off in the distance?

Instead of a field of poppies, though, a lush, textured, and completely native meadow will be springing up this summer. The meadow will be replacing a swatch of non-native, monochrome grass as part of a larger effort to revitalize the Panther Hollow Watershed.

You may be asking yourself: Why remove a field of grass? Doesn’t grass absorb rainwater, keeping it out of our sewer system?

Answer: Yes and no. Grass does absorb a bit of rainwater. But with its shallow roots and often compacted soil underneath, it can almost as hard as a slab of concrete for water to penetrate. On this hillside between Bartlett and Beacon Streets, towards the upper sections of the Panther Hollow Watershed, we see a stellar opportunity to reduce environmentally-taxing maintenance (read: mowing), establish a walking path, and capture rainwater in the ground rather than having it run right into our sewer systems.

Like many older cities, Pittsburgh has a combined sewer system in which both stormwater and sewage flow in the same pipe. The system is prone to overflows, with rainfalls greater than ¼ inch triggering large quantities of untreated sewage to discharge into our rivers. By increasing the amount of water retained in the soil throughout the watershed, we’re keeping rainwater out of the park streams and City sewers. This project is the first stage of a plan to reduce the volume of water flowing through the watershed.  This summer and fall, infiltration trenches and berms will be created along the street. Combined, these projects will remove an estimated 1.7 million gallons of water from the combined sewer system.

As the grass on the hillside along Beacon Street dries out, we ask that everyone stays on the marked path so that the meadow seedlings have a chance to really take hold. The seed mix that we’re using can handle the foot traffic anticipated for the Vintage Grand Prix. Until then, excuse the look of this meadow-in-progress and look forward to a ‘low-mow’ biodiversity magnet and an overall green improvement in Schenley Park!

This project is done in collaboration with the Allegheny County Sanitary Authority (ALCOSAN), Pittsburgh Water and Sewer Authority (PWSA), and the Department of Public Works (DPW).

Thank you to the generous funders who are making this project come to life. We’d like to thank Allegheny County Conservation District, Dominion Foundation, Western PA Conservancy, Foundation for Pennsylvania Watersheds, and The Pittsburgh Foundation for their support!

When You’re 84 and Live in the Park

When you’re 84 and live in the park, you’ve got to be tough. You’re going to get drenched, frozen, and sit through the sunniest and windiest days. You’re going to shift a bit, crack under the pressure, and start to show wrinkles — all a natural part of aging.

When you’re 84 and live in the park, sometimes you don’t get the respect you deserve. Kids come along, and they just don’t get it. These whippersnappers get out their pens and pocket knives and leave their mark, not even taking the time to get to know you or your history.

But when you’re 84 and live in the park, there are tons of people that have your back. They keep you shiny and clean, put together and graffiti-free. With their help, you have a chance at staying as handsome as when you first came to live in the park so many years ago.

On a soggy December day, a handful of staff from the Parks Conservancy and the City of Pittsburgh were audience to a crash course in graffiti removal at a landmark that’s been living in Schenley Park since 1930: Westinghouse Memorial. Led by Tom Podner of McKay Lodge Fine Arts Conservation Laboratory, a nationally renowned art and artifacts conservation center and the studio that worked magic on Mary Schenley’s fountain and the Highland Park entry gates, this training also included an extensive walk-through of the construction of the memorial. If you’ve never really looked at this beautiful tribute to George Westinghouse, we recommend getting up close and personal next time you’re visiting. The bronze “The Spirit of American Youth,” intricately detailed panels, and all of the amazing details that went in to the entire work — just outstanding.

For those of us that work to maintain and restore the parks and their many historic landmarks, it’s hard to understand vandalism. In the short time between when the men of McKay Lodge had done their first day of assessment and cleaning and the second when they were giving us the lesson, there was already new graffiti on the memorial. Luckily, Tom and his crew are pros at finding the right tool for the job. Lucky for us, one of those tools was a blowtorch.

Starting with the gentlest solvent first, Tom took a couple swipes across the surface of the memorial at a spot where graffiti had literally popped up overnight. He always starts with the weakest solutions first to judge to depth of the scratch or mark. Like washing a child’s scribble off a wall, he took the first marks off pretty easily.

The center panel on the front-facing portion of the memorial was the real task at hand.

A botched graffiti cleanup in the past (not done by McKay Lodge) had left a large white streak on one of the most visible parts of the memorial. As Tom soaked a clean cloth in that same base-level solvent, he explained the different layers of the memorial — the actual memorial, a clear protective coat, and a layer of wax on top. This layer of wax, which takes the hardest beating from the elements, optimally should be refreshed every few years. (Until now, the memorial has seen many years of neglect. The Park Conservancy is actively working to raise funds for a long-term maintenance plan.) This layer keeps memorials looking crisp and clean. And holds pen and marker inks.

The first solvent a wash, Tom reached for the tool we all secretly wanted to see him use: the blowtorch! The discoloring, he explained, wasn’t on the surface-level wax; it looked to him to be moisture that was caught between the wax and clear coat. By using the torch, he was melting the wax and wicking away the moisture from the clear coat. It started to disappear like magic; he invited us to touch the metal right after he worked on an area — the metal was completely cool. He finished the job by buffering on a fresh layer of wax where there once was a big white splotch.

There’s always work to do in upkeeping wonderful park places and features such as the Westinghouse Memorial. The memorial has a long way to go, as we plan to clean and repair it, shore up its foundation, and restore the surrounding Lily Pond. On a larger scale, the memorial will tie into our Panther Hollow restoration work as we plan perimeter landscaping and restoration. If you love this 84-year-old in the park, please consider a donation to keep it looking its best.

A Race with the Red Queen

No disrespect to the ancients, but the best time to plant a tree was not 20 years ago. It might be this spring.

Whether plant, animal, virus, or bacteria, all living organisms are locked in battle with the pathogens, pests and parasites in their surrounding environment, using the tools and tricks nature’s equipped them with to keep them in the game. One of the strongest tools in this arsenal? The ability to adapt, to one-up opponents in a constant arms race.

One huge task that the Parks Conservancy faces is shoring up this arsenal for the trees in our care. The founders of these fine parks left quite the legacy, not only in the consideration that they gave to the design and experience of the parks, but also the impressive diversity of the urban forests.

It’s tough to overstate the importance of biodiversity to healthy parks. Voracious pests and sneaky diseases gain a slight foothold within the bounds of our parklands and spread like wildfire, faster than we can catch and quarantine them — even with sharp eyes out at all times. Our trees need their natural defenses as they stand on the front lines of these attacks, especially since they face added stresses of living in the city: polluted water, poor air quality, micro-climates, and human intervention.

London plane tree in Schenley Plaza.

A general in this battle, the Parks Conservancy’s Director of Park Management and Maintenance Phil Gruszka is a seasoned veteran. Phil has been rocking war paint for years now. Since conducting a study with Dr. Cynthia Morton of the Carnegie Museum of Natural History, he’s realized that our legacy park trees are impressive in their biodiversity… but that we have to really work to keep it that way. Their study found that tree stock from major nurseries across the country have actually been whittling down the tree gene pool.

“When London plane trees were first introduced to the United States, one nursery had a tree that did very well. But they couldn’t get it to reproduce from seed, so they started getting cuttings to grow out. Then they released it to the trade and named that cultivar ‘Bloodgood.’”

Selected for it’s superior resistance to the fungus anthracnose, the cultivar (a plant chosen for its particular genetic makeup) Bloodgood has been spread around now for about 30 years, dominating nursery stock of London planes. Plane trees bought from nurseries have identical genetic material to every other plane tree — they have not been grown from seed from two parent trees. They’re clones.

“Today, if I wanted to replace a London plane, I can only buy the cultivar Bloodgood.”

But trees from Schenley Plaza and around the park surprised them. “The Schenley Plaza trees were all genetically different, very diverse.” The park trees, planted before Bloodgood started to gain popularity, were much more diverse than the current nursery stock. The surviving 100, of the 200 that were planted years ago, were of a strong and diverse population, toughened from years of fighting off pests and disease.

Then, they widened their net. Was this true only for London planes? How much more diverse are our park trees than trees sold around the country? After polling nurseries from various parts of the country, they found that ten common trees used all over the U.S. were clones — their genetic diversity was actually getting less and less diverse.

Red oaks with oak wilt in Schenley Park, soon to be cleared.

Why has this study been so important? As the Parks Conservancy has taken on ecological restoration projects in the parks over the years and established the Park Tree Action Plan with the City of Pittsburgh, TreeVitalize, and Tree Pittsburgh, we’ve actively worked to increase biodiversity in the parks. Taking cuttings of our own heterogeneous tree stock, we’ve started growing new trees around the park and city in our own sort of diversity study, learning as we go about resistant new cuttings that withstand biological threats. This knowledge gives us only a peek at the immeasurable value of Pittsburgh’s parks; less mature forests and parks elsewhere are markedly more homogeneous, posing a threat to themselves and surrounding forests against the pests and diseases that have shown an uptick in recent years. Our trees are better equipped to keep our parks healthy and beautiful.

This week, a large stand of red oaks — about 50 trees in total — will be cleared from Prospect Drive in Schenley Park. Oak wilt, discovered earlier this year by an observant park user, got a stranglehold on the interlocking root system of the trees, infecting an entire grouping of trees. Left there, the trees are a risk to the health of other park trees. It’s terrible to have to take down so many trees, but it’s something that needs done for the overall well being of the park. And when these trees are replanted in the spring, a variety of new and diverse tree stock will be added to the expanding biodiversity and health of the park.

That First Ride

The best place for that glorious first bike ride is now open for cruising.

Nothing comes close to the thrill of the first ride. It could be the first time you wobbled along after the training wheels came off, or when the ice and snow finally melt so you could venture out for the first ride of the season. Whether you’re eight or 80, we very happily encourage you to take that first ride on Pocusset Street.

A ‘road shift’ of Pocusset connects Squirrel Hill to Greenfield via non-motorized roadway in Schenley Park

The first of its kind in the nation, Pocusset Street is a successful experiment in ‘road shift’, a term coined by Bike Pittsburgh. The project, spearheaded by Bike Pittsburgh and the City of Pittsburgh, was all about rethinking and resizing this paved surface, taking a structurally unsound and sharply curving through-street and creating a safe — and repaved! — avenue for bikers and walkers through Schenley Park. Linking Squirrel Hill to Greenfield, Pocusset Street has been shifted into a very sleek and safe thoroughfare with ‘lanes’ for bikers, wide shoulders for walkers, new LED street lighting, and reflective bollards that bar motorized traffic. Now, it’s a road for everyone.

The recent installation of the bright yellow candlestick bollards are the final pegs in this redesign. The project is a real testament to committed community members; with the support of neighbors, a road that would have normally been shuttered has contributed tremendous value to the park. On a larger scale, Pocusset Street is another step for connected bikeways through Pittsburgh and is definitely something worth bragging about on a national level (did we mention the perfect timing?)

Jump on Pocusset Street as the weather breaks for a cruise with a sweeping vista to one side and the park to the other. Bring along your friends, your grandparents, your little one with the training wheels — anyone you want along for that first ride.

Remember your first foray on two wheels? Roads like Pocusset make the parks bikeable and enjoyable for everyone. This spring, enable an awesome child to get out in the parks to ride a bike of their own through Variety the Children’s Charity “My Bike” program. Through this happy project, children with special needs are outfitted with a bike specially tailored to their disabilities. Currently, they have 150 souped-up bikes for eligible kids that fill out the application before April 1st. Spread the word!
