This is the final installment in a 19 part series on urban parks and stormwater. The following is excerpted from City Parks, Clean Water, a report by The Trust for Public Land’s Center for City Park Excellence.
Parks can help solve some city stormwater problems, and sometimes stormwater agencies can actually contribute funds to redesign or upgrade parks. However, stormwater funding alone is rarely sufficient for an entire park project, so it is usually necessary to piece together funding from multiple opportunities.
In many places, small-scale construction happens frequently and with little fanfare. Philadelphia’s water department routinely pays for park upgrades in conjunction with stormwater projects – from basketball courts to splash-pads to quaint pedestrian bridges. So do agencies in Austin, the Boston area, and Milwaukee (even if the water bureaus sometimes do so on their own land and avoid using the word “park” for legal reasons).
In Baltimore, a small but unusual source of funding is the Maryland Port Administration, proving that the number of possible cooperators is limited only by people’s imaginations. Because the Port of Baltimore is unable to operate without maintaining a vast acreage of paved surfaces, and because the state has a strict law protecting a 1,000-foot buffer around Chesapeake Bay, a compromise needed to be worked out. Thus, after doing everything possible to capture storm runoff on-site, the port agreed to remove hardscape elsewhere, depaving an acre for each acre it surfaces at the port. After experimenting in a rural state park’s parking lot, the port implemented the program in Baltimore, tearing out swaths of asphalt in nine schoolyards, trucking in good soil and providing the students with green ballfields and play areas. Next on the greening list may be venerable Patterson Park which over the years has accumulated more than an acre of miscellaneous asphalt that is ugly, unneeded, and adding to the runoff burden in the city and in Chesapeake Bay.
“We do a good job,” said Phillip Lee, a consultant to the port. “We’ll spend up to about $150,000 an acre taking out pavement and replacing it. Sometimes we put in swales, too. The rules are that the land has to be public and they have to promise that it will stay unpaved in perpetuity.”
In order to reduce delays to its own construction program, the port has gone a step further and created a “bank.” Now, when it completes a pervious project in advance, it puts the credits into the bank, allowing it to pave another acre of port land when needed without delay.
Funding may often pose a challenge for water management projects, but with some creative thinking there may actually be a win-win solution for everyone involved.
