New Resources on Trees and Stormwater

The Center developed two guidance documents to help communities across the country bring more trees into their neighborhoods. The resources draw upon one of the Center’s unique areas of research: the use of trees for stormwater management. The work was funded by the USDA Forest Service. The resources, described below, were developed with input from experts in stormwater engineering, urban forestry and other relevant disciplines. Accounting for Trees in Stormwater Models: This paper is intended to help the stormwater engineering community more easily account for trees in runoff and pollutant load calculations and incorporate them into stormwater management strategies. It [...]

Creating “Forest-Friendly” Developments to Help Save the Bay

A new publication from the Center for Watershed Protection can help Chesapeake Bay communities review and revise their development regulations to ensure future construction projects maximize tree canopy. These “forest friendly” developments conserve and protect valuable trees and woodlands, encourage new plantings and will help Bay states meet the Watershed Implementation Plan (WIP) goal to expand urban tree canopy by 2,400 acres by 2025. Making Your Community Forest-Friendly: A Worksheet for Review of Municipal Codes and Ordinances provides a set of questions to help determine whether existing local codes require, allow or prohibit forest-friendly development practices. Trees and forests capture [...]

Phosphorus Release in Stormwater Ponds

Greetings, stormwater professionals: The Minnesota Cities Stormwater Coalition and Saint Anthony Falls Laboratory hosted a joint presentation on July 19th focused on Phosphorus Release in Stormwater Ponds. Some highlights and follow-up from this event are provided below. Here in Minnesota, we have recently found that a number of our constructed stormwater ponds are releasing and discharging significant amounts of phosphorus from sediments. This is the reverse of the expected net phosphorus retention that we expect. This raises a number of important questions. We thought these could be best addressed through an event that involved a couple research presentations and a [...]

Gwinnett County, GA Stormwater Management Manual Training

The Center’s work on improving stormwater management in Georgia continues to expand.  With assistance from the Center, the Georgia Stormwater Management Manual was published in 2016.  The Manual updated the rules regarding better site design, water quality best management practices, and perhaps most importantly, introduced the concept of Runoff Reduction (application of strategies that minimize the increase in runoff associated with developed lands) as a means for improving water quality. In response to publication of the Georgia Stormwater Management Manual, Gwinnett County published its own version of the Manual. The Gwinnett County Stormwater Management Manual largely mirrors the statewide version [...]

Helping Pennsylvania Municipalities Work Together to Achieve Cleaner Water

In Pennsylvania, many local jurisdictions are grappling with the complexities of stormwater and watershed restoration practices as they develop and implement Pollution Reduction Plans as part of their EPA National Pollutant Discharge Elimination System (NPDES) stormwater permit requirements.  In some parts of Pennsylvania, local regulated jurisdictions are uniting at the county-level to combine resources and identify the projects that are most cost-effective and beneficial to the larger community. The Blair County Intergovernmental Stormwater Committee (ISC) is an example of such a collaborative.  In 2017, the Center worked with the ISC to develop and submit a Pollution Reduction Plan that covers [...]

Veterans Memorial Park upgrades successful in first test

By Jane Bellmyer of the Cecil Whig RISING SUN — With the work at Veterans Memorial Park finished Brian Seipp, watershed manager with the Center for Watershed Protection, waited for the rain to fall to assure his months of work there was successful. And it was. Even in the torrential downpours of late the stormwater remediation project at the Rising Sun park successfully kept the town property off Wilson Road from going underwater. “This was the biggest project we’ve done in Rising Sun,” Seipp said of the grant funded $634,700 effort that redirected and redesigned the creek and added drainage [...]

Ellicott City’s Main Street is too risky to reopen businesses post flooding

Once again, Ellicott City has been drowned by torrential rain and ravaged by deadly flood waters. It was painful to witness yet another devastating flood in this old and beautiful town, but it wasn’t surprising. I serve as executive director of the Center for Watershed Protection, a nonprofit based in Ellicott City that provides watershed and stormwater management consulting services to state and local governments and other clients. Our downtown offices were flooded several times before we moved to higher ground in 2014 — an ironic outcome for a stormwater management organization. While our reasons for moving went beyond flooding, [...]

Ellicott City rebuilding may require ‘drastic’ changes

By: Adam Bednar Daily Record Business Writer May 29, 2018 Any rebuilding of historic old Ellicott City requires profoundly rethinking the use of the former mill town, according to one expert. Hye Yeong Kwon, executive director of the Center for Watershed Protection, warned that the area is in a flood plain and would be inundated by water again. While there have been efforts to mitigate the impact of flooding, she said, ultimately there’s only so much that can be done because of its location in the Tiber-Hudson watershed. “It’s in the flood plain … if we’re going to invest in rebuilding [...]

Targeting Regulatory Protections to Vulnerable Forests in the Delaware River Watershed

Through a grant from the Delaware Watershed Research Fund, the Center is working in partnership with Rutgers University and the Pinchot Institute for Conservation on a research project which seeks to improve water quality in the Delaware River basin. The project includes a review of municipal codes and ordinances related to riparian (streamside) buffer and forest protection. This information, together with forest cover and development pressure data, will improve our collective understanding of how to provide effective protection for forests during development using municipal regulations. This project began by establishing an advisory group to discuss and recommend where to focus [...]
