Paving contradicts the Public Trust Doctrine . That doctrine says city parkland cannot be dedicated for non-park use. Creating a regional bike trail with a “continuous surface” or the Empire State Trail as some have stated is dedicating the trail for activities that take place primarily outside of the park.  here

Below is the official sign posted at the Stables showing the Parks Department considered the Putnam Trail a nature trail. It was removed in 2018.  (photo: MTurov.)


A rationale for paving was to link the South County Trail to 225th street. The video below shows the trail south of the park will become increasingly flooded in coming years.

An explanation of the above video is here showing why the Putnam Trail and landscape below the park may be flooding in coming years, according to scientific projections.

DOT specs say that paving the trail with asphalt allows for speeds of 20 mph.  The trail inside the park runs through a rare ecosystem.  Animals that breed in the area or visit include rabbits, chipmunks, species of turtles, butterflies, insects, birds, ducks, muskrat, skunk, raccoon, wild turkey, bullfrogs, salamanders.

The graphic below is a comparison of maintenance costs, pg. 28, Maintenance Practices and Costs of Rail Trails, June 2015. Maintenance is not more costly for non-asphalt surfaces than for asphalt surfaces. This data is consistent with data provided by trail orgs and engineers. asphalt v stone-dust

Central Park, another flagship park, restricts bikes to the Drives, forbidding them on park paths.  Central Park has perimeter drives and Van Cortlandt Park has major greenways. There’s a recently-built protected bike lane along its western edge of the park from Yonkers to the 242nd St subway.

Letter from Sen. Jeff Klein and Assemblyman Jeff Dinowitz asking the Parks Department for a 4(f) environmental review (which ultimately never occurred.)

A paved surface allows for bike speeds of 20 mph, according to DOT specs.  The trail runs through a rare wildlife nature area. Potential speeding is a critical public safety issue – see Olenick vs. NYC, a lawsuit about multi-user path designs. No public safety study as far as we can tell was done for this design.

A CB8 committee chair said in Sept 2018 that they’ll manage conflicts between users after it’s built, This was echoed by Councilman Andrew Cohen at a December 2018 Townhall.  The Olenick vs NYC case says multi-user conflicts should be considered during the design phase, not later.

In August and September 2014, (click on link) almost a year following the 2013 NYSDEC public hearing at Lehman College, the parks department said they were redesigning the trail to a permeable surface in response to public comments at a public hearing and NYSDEC’s suggestions.

The Parks Department posted a version of the Masterplan in June-July 2014 that was not the version voted on by CB8.  The March Masterplan (click on blue link) did not say the Putnam Trail would be paved (pg 30).  Two months later, the Master Plan posted online did.

In January 2016 when the new paving plan was presented to the P&R Committee in a public hearing, a CB8 member pointed out the codicil approved 2 years before that said all trails should remain permeable, nontoxic, and suitable for wetlands.  However, the Committee Chair said that he personally did not mean to include the Putnam Trail. Others claimed that the Putnam Trail was “grandfathered out” of the 2014 codicil voted on by the full board, possibly a reference to the 197a plan of 2003. 2003 was many years before public hearings occurred or any environmental assessment made about the trail.

Paving is not required by federal funding.  The same federal funding finances unpaved trails throughout the state of New York. 


Millions of gallons of Tibbetts Brook water flow into the lake each day, made worse when it rains, resulting in CSO’s (combined sewer overflows) being discharged into the Harlem River.

The area around the trail inside the park meets New York State’s definition of environmentally-sensitive areas by offering aquifer recharge, open space, unique character, wetlands and wildlife habitat. (NYS Environmental Quality Bond Act of 1986)

Nearly 3,000 people have signed a petition against the plan and dozens have shown up for public hearings.

The Trail runs through one of the last remaining freshwater wetlands in the city.  NYSDEC said it has a biodiversity seldom seen in the Bronx.  The city has said that preserving wetlands are prioritized above other land uses.

Original federal funding mentions nothing about paved regional greenways with continuous surfaces or state greenways.

There is no bird-watching and nature-viewing on the South County Trail.

A Parks Department document written in 2013 says that construction projects inside the park have harmed the park. Their recommendation is that agencies should get together and remove asphalt in the park.  Some quotes from that study:

The abundance of impermeable surfaces in urban environments prevents rainfall from percolating into the soil, resulting in large volumes of stormwater that erode soil, decrease water quality in aquatic habitats, and burden sewer systems.   Natural areas have the capacity to detain and store stormwater. Regional, interagency collaboration could help reduce runoff by minimizing impermeable surfaces and increasing the acreage of absorptive green spaces.”  pp 52-55

Scientific data shows that 50% of  the world’s wildlife has disappeared in the last 40 years due to loss of wildlife habitat and development. (click here for National Geographic article)


No hydrology study or EIS was done.

The wetlands mapping that NYC Parks was required to do left out vernal pools.

Vernal pools form every spring within 30 ft of the Putnam Trail, containing various invertebrates. They are the living seasonal connection between the different segments of the wetland inside the park.

The Putnam Trail runs through state-protected wetlands and city-designated Forever Wild Preserves and (map included in the VCP Masterplan) Van Cortlandt Park’s wetlands are YO-1 classed wetlands — the highest classification. NYSDEC described this area in 1987:  “This wetland has a diversity of wetland communities seldom equaled in Bronx County and contains habitat types found nowhere else in the Bronx.” The wetlands are protected by the state and federal government. At one time there were 224,000 acres of freshwater wetlands in the city which is down to 2,000 acres today. The area meets New York State’s definition of environmentally-sensitive area by offering aquifer recharge, open space, unique character, wetlands and wildlife habitat. (NYS Environmental Quality Bond Act of 1986)

The trail being improved is an opportunity to improve the health of wetlands, lake, and river, and ultimately the health of every New Yorker.

What we “share” is biodiversity; we share bird life, shy woodland creatures, one of the last remaining wetlands in the Bronx and New York City; we share clean water and air, and the irreplaceable experience of deep serenity that only nature can provide. We share rabbits, frogs, turtles, chipmunks, muskrat, and nesting birds to young and old, and future generations. We share what is not compatible with a widened, asphalt-paved “greenway.” Van Cortlandt Park is not Riverside Park or Central Park. It possesses the wide array of recreational amenities, but also ecosystems that are available to all. Good stewardship supports non-fragmentation and context-sensitive changes.
