Evaluating Nature-Based Strategies for Flood Risk Reduction and Ecological Restoration in Eastwick
Abstract: Eastwick and Tinicum residents in southeast Pennsylvania have experienced increasing catastrophic and chronic flooding in the last decade. Additionally, climate change impacts will exacerbate future flooding and residents are disproportionately experiencing these climate change impacts in real time. As climate change exacerbates the effects of storms, flooding and erosion, the lives and livelihoods of these residents in the Lower Darby Creek Watershed will be at even greater risk. The goal of our project is to identify and evaluate nature-based strategies for flood risk reduction and ecological restoration that could complement ongoing project designs. Building on the previous planning efforts and in coordination with the US Fish and Wildlife Service, local government, community leadership, and property owners, the team is meaningfully engaging with stakeholders to identify, evaluate, and select habitat restoration strategies. Strategies focus on both short- and long-term actions that promote ecological and community resilience. Based on strategies identified and feedback, the team performed an Alternatives Analysis for the nature-based strategies. The analysis considered performance (flood risk reduction – both storm and sea level rise related – and ecological restoration potential), cost, constructability, public access and recreation opportunities, and operation and maintenance.

Breakout Sessions
Breakout Sessions 1
A. Establishing Riparian Forest Buffers with Stroud Water Research Center
Heather Titanich and Calen Wylie, Stroud Water Research Center
Room: BH Lecture Hall 014
Abstract
The first half of the presentation will look through how Stroud Water Research Center designs, installs, and maintains riparian buffers. The second half of the presentation will look through Stroud’s methodology research in to forwarding riparian buffer success. The combined intent is to showcase how we do buffers and why we made those decisions.
B. Third River Urban Park & Habitat Creation Project
Ivy Rose, Princeton Hydro, LLC
Room: BH002
Abstract
In urban Bloomfield, New Jersey, a former brownfield situated within a 100-year floodplain was transformed into a public park featuring 4.2-acres of constructed wetland that is teeming with wildlife and a diverse array of native plant species. This project is an example of how green infrastructure can re-establish lost wetland ecosystem functions and values within an urbanized watershed through attenuating floodwaters, increasing flood storage periods, and providing attractive foraging and breeding opportunities for wildlife.
The project was successfully closed out in 2024; however, monitoring will continue indefinitely to gather long-term data of the constructed wetland’s functions and values. This presentation will illustrate the project’s history and provide post-closeout updates on the site’s current conditions.
C. Legacy of Pennsylvania Coal: Mercury in Schuylkill River Riparian Soils
Abe Doroshow, Alain Plante, Jon Hawkings, University of Pennsylvania
Room: BH005
Abstract
During the Schuylkill River Project of 1947-1951, engineers dredged large amounts of anthracite coal sediment from the river and deposited it in riverside impounding basins for reclamation as fuel. Legacy coal contamination is still visible in riparian soils that are frequently mapped as the Gibraltar soil series, characterized by “coal washings deposited over alluvium.” A series of soil profiles were sampled from Pennsylvania State Game Lands 234 in a transect away from the Schuylkill riverbank and analyzed for the toxic element mercury (Hg), a main environmental source of which is coal combustion. We measured total Hg, mobile Hg fraction, and percent coal. Hg concentrations in Gibraltar samples were elevated over uncontaminated samples, and Hg was correlated with increasing percent coal. However, the average Hg content of Gibraltar samples significantly exceeded the typical Hg content of Pennsylvania anthracite. These findings suggest that these coal-containing sediments may be a sink for retained Hg rather than its source.
D. Funding Realities: Adapting Land Acquisition Strategy to Local Context
Kyle Rose, Natural Lands
Room: BH001
Abstract
Land conservation projects often rely on external funding to acquire fee simple ownership or secure conservation easements. Yet the funding landscape is far from uniform. The viability of any given acquisition depends on a complex mix of factors: location, size, synergy with local and regional plans, the ownership type of neighboring parcels, the identity of the final landowner or easement holder, and whether public access is anticipated. In southeastern Pennsylvania, these challenges are compounded by uneven access to grant funding at the county and municipal levels. Some counties administer robust open space programs; others offer none. Municipal support varies just as widely.
This patchwork of funding availability creates significant disparities in which parcels can realistically be conserved – regardless of ecological value or community interest. This presentation will explore how practitioners navigate this fragmented funding terrain, offering examples of how local context shapes acquisition strategy. We’ll examine how partnerships and creative funding combinations can help close gaps in the “funding puzzle.” Attendees will leave with a clearer understanding of how to assess feasibility and adapt acquisition approaches to local funding realities.

Breakout Sessions 2
F. Greening Our Schools: Stormwater Solutions for the Schuylkill
Samantha Huxley, Rippled Waters Engineering, LLC with Marguerite DiGiorgio and Allison Hartman, Partnership for the Delaware Estuary
Room: BH Lecture Hall 014
Abstract
Rippled Waters Engineering partnered with the Schuylkill Action Network to create conceptual green infrastructure designs for four local schools in the Schuylkill Watershed. This project brings together science, education, and community to improve local waterways while inspiring the next generation of environmental stewards. Each school design focuses on solving real problems—such as flooding, erosion, and poor water quality—by using nature-based solutions that manage stormwater where it falls. Proposed features include rain gardens, biofiltration swales, and streambank restoration, which reduce erosion and filter stormwater runoff before it reaches nearby streams. Beyond their environmental benefits, these designs also create vibrant outdoor learning spaces for students. Native pollinator gardens, educational signs, and visible stormwater features help students see how green infrastructure works and why it matters. By transforming everyday schoolyards into living laboratories, the project connects students and community members to the health of the Schuylkill River and its watershed. These conceptual designs lay the groundwork for future projects that will make local schools greener, more resilient, and better connected to the natural environment around them.
G. Native Plants in the Landscape – A Trajectory of 35 Years
Jim MacKenzie, Octoraro Native Plant Nursery
Room: BH002
Abstract
We’ll discuss early adapters, current status, influences and future trends of native plants in the landscape including regulatory and non-regulatory factors. Topics will include high-level design, planning, application and maintenance practices. Focus will be on the mid-Atlantic region.
H. Mine Pool Mapping in the Upper Schuylkill Headwaters to Consolidate AMD for Treatment
Bobby Hughes, Eastern Pennsylvania Coalition for Abandoned Mine Reclamation
Room: BH005
Abstract
EPCAMR Executive Director will provide an overview presentation on mine pool mapping efforts in the Upper Schuylkill Headwaters concentrating on the Pine Knot, Oak Hill, and Repellier AMD discharges that are currently being monitored with the Schuylkill Conservation District and other partners to determine future AMD Treatment in the watershed. An overview of the mine pool mapping will be presented that will give the audience a closer look at the tedious and time consuming process of preparing surface and underground mine maps for further analysis to determine mine pool elevations, storage potential, whether or not the mine pools are flooded, and conservative estimates on remaining coal volumes and mine pool volumes underground based on the best available historic mine maps that can be found on the Mine Map Atlas.
I. Dam Removal and Riparian Restoration in the Valley Creek Watershed
Ray Clarke, Open Land Conservancy of Chester County
Room: BH001
Abstract
A small tributary to Valley Creek (EV) that flows through Open Land Conservancy’s George Lorimer Preserve had been dammed for prior farmland use. The smaller of two dams was eroding dangerously. The presentation will discuss solutions, removal of the dam, restoration of the stream channel and riparian habitat restoration. It will also cover a subsequent adjacent downstream project to remove invasive bush honeysuckle and plant with native trees, shrubs and perennials. The challenge going forward is how to deal with the much larger, sediment loaded, downstream dam. The presentation will discuss how a small all-volunteer land trust has approached this issue, and the importance of professional supplier and funding partnerships.
J. Introduction to the Society of Freshwater Science EPT Exam
Nicholas Macelko, Neshaminy Watershed Association
Room: BH008
Abstract
The presentation will be broken into three parts.
An explanation of what the SFS exam is, who administers it, and where an interested party can go to learn more.
The importance of the SFS exam, which is that two SFS certified individuals are needed for an organization to submit tier 3 data to the PA DEP.
A runthrough of taxonomic keys such as those found in “An Introduction to the Aquatic Insects of North America”. As well as an introduction to preserved or living examples of the mayflies, caddisflies, and stoneflies that may be found in those keys / inhabit the Delaware watershed.
Due to the recent invasions of insectivorous species such as Virile crayfish, Rusty crayfish, and Oriental weatherfish on the Delaware River it is important for our organizations to push individuals to document what conditions look like now before these species become established and change the invertebrate communities of our watershed.

Hydrological Influences on the Flux and Phase Distribution of Trace Metals in the Schuylkill River
Zihan Geng, University of Pennsylvania
Abstract
Urban rivers often receive heavy metal inputs from road dust, building runoff, and atmospheric deposition. When rainfall or flooding changes the water flow, these trace metals can shift between dissolved and particulate forms, which affects their mobility and ecological risk. This project aims to study how hydrological conditions and seasonal changes influence the flux and phase distribution of trace metals, specifically Cd, Pb, Zn, Ni, Cu, and Cr, in the Schuylkill River of downtown Philadelphia. The goal is to understand whether rainfall events affect the transport of particulate metals and how this varies between wet and dry seasons.
River water was collected during both baseflow (dry) and stormflow (rainy) periods. Samples were filtered to separate dissolved and particulate phases. The particulate fraction underwent the first and last step of the BCR sequential extraction method to isolate the labile metals, and the total metal content, which was then analyzed using ICP-OES and ICP-MS. The concentration data were combined with flow rate records from USGS to calculate total metal loads. By comparing results between seasons and hydrological conditions, the study evaluates how rainfall, runoff, and sediment resuspension control metal transport in this specific urban location. The results will reveal clear seasonal and hydrological trends in labile metal behavior. These findings will provide insight into how climate-related changes in rainfall could alter metal pollution dynamics in urban rivers. Ultimately, this research will help improve understanding of contaminant transport under future hydrological extremes and support better water-quality management strategies.

L. Olmsted Woods: 25 Years of Restoration and Research
Michele Adams, Meliora Design
Room: BH002
Abstract
Olmsted Woods, located on the grounds of the Washington National Cathedral, Washington, DC, has faced significant challenges due to drought, stormwater runoff, flooding, invasive species, and the broader impacts of climate change and urban development. Designed by renowned landscape architect Frederick Law Olmsted Jr., the plans completed in 1910 and 1924 emphasized the preservation of this five-acre woodland as a sanctuary for contemplation and reflection.
Olmsted Woods are cared for by the All Hallows Guild, which has undertaken extensive efforts to preserve and restore this vital natural space for many decades. In 1997, stormwater erosion gullies had cut ravines into the wooded hillsides, resulting in soil moisture changes and the decline and loss of many large trees. Deer browse had stripped the landscape. A comprehensive ten-year plan was developed and implemented, incorporating a range of green stormwater infiltration practices, forest restoration, and an invasives management plan to restore the forest.
In 2024, the Guild revisited the forest restoration work completed in 2002, inspecting and monitoring the stormwater infiltration practices, forest restoration, and gully stabilization techniques implemented two decades ago. This presentation will share the successes and challenges faced over 25 years of continuous work on this five-acre urban forest site.
M. Road Salt Intrusion Drives Changes in Wetland Plant Communities in Great Marsh, Pennsylvania
Benjamin Langey, Ducks Unlimited/Great Marsh Institute
Room: BH005
Abstract
Freshwater salinization, especially the use of road salts for deicing, poses significant threats to freshwater wetlands. The Great Marsh in Elverson, Pennsylvania, is a unique and valuable freshwater ecosystem, and the largest contiguous freshwater wetland complex within the highly developed Philadelphia suburban landscape. To investigate the effects of road salt intrusion on emergent wetland vegetation communities, I quantified sodium and chloride concentrations in shallow soils and groundwater and collected vegetation abundance data along transects extending into the Marsh from the Turnpike. I did not find a significant difference in mean deicing ion concentrations in either medium with increasing distance from the Turnpike; however, deicing concentrations were more variable in sampling points closest to the Turnpike. I found that species diversity indices decreased as a function of increased deicing concentrations in shallow soil, but not shallow groundwater. In my study area Phragmites australis was significantly more likely to be present in areas with high concentrations of deicing ions in shallow soil, but not shallow groundwater. Finally, P. australis presence and deicing ion concentrations in shallow soil and shallow groundwater were the only significant predictors when considering other physical and biological factors impacting vegetation diversity.
N. Research to Riverbanks: Collaboration for the Workforce of the Next Generation
Brent Erb, Nolde Forest Environmental Education Center, and Anna C. K. Erb, DSW, LCSW
Room: BH001
Abstract
Contemporary environmental challenges, including pollution, flooding, and climate change, pose significant threats to society, yet their impacts disproportionately affect marginalized individuals and communities. This interactive session is designed to explore global and regional examples of how environmental issues intersect with social and economic inequities, situating these themes within the local watershed. Building on lessons learned from recent research on collaboration among educators, school counselors, and partners, the discussion will explore strategies to expand awareness and access to environmental career pathways while advancing our common mission of community engagement and stewardship. We’ll conclude the session with a facilitated discussion and short interactive activity to identify concrete steps for improving outreach and collaboration to build upon our work in ways that are more inclusive. Participants will leave with practical strategies and resources to transform awareness into collective action.
O. Tools to Promote Safe Recreation and Information Sharing
Prem Trivedi and Alexander Wynne, Riverways Collaboration
Room: BH008
Abstract
Participation in on-water recreation in the region is estimated at 20,000–35,000 users annually and continues to grow. That’s like filling up a local sports stadium with paddlers! However, many communities on both sides of the Delaware River still lack safe and monitored access points near their neighborhoods and often use informal sites that have not been evaluated for safety. Riverways members have worked over the last 15 years to develop programs and access points, but the need remains significant. Riverways Collaboration was established in 2017 to ensure that organizations working in environmental education had the shared infrastructure and capacity needed to promote equitable recreational access to waterways in Philadelphia and Camden. As part of this effort, the consortium has developed a robust set of shared tools that guide program design and implementation, on-water safety, risk management, and evaluation. In this session, we will share information on our monitoring program, communication strategies, and data portal. These tools are helping us spread the word about paddling safety and access, since many residents in the tidal Delaware River (Trenton to the Delaware Bay) are unaware of the recreation programs and possibilities.
