I Can’t Think When It Rains

One month ago, every community in Pittsburgh experienced a life-altering trauma.  For some, the Tree of Life shooting directly touched their family. For others, the events triggered the memory of an equally horrifying experience. But much like the attacks on the World Trade Center, every one of us will remember where we were on the […]

Pittsburgh River Towns Unite to Create Triboro EcoDistrict

Environmental issues do not observe political boundaries. As rivers and valleys tie regions together, they equally bind diverse communities to a shared future. In Pittsburgh, the three river towns of Millvale, Etna, and Sharpsburg are forging their own connections, and the newly launched Triboro EcoDistrict promises to be a model for neighborhoods around the country.

Stormwater Management Lunch & Learn: Kleinschmidt’s Hemlock Farms Project

Kleinschmidt logo

GBA and 3 Rivers Wet Weather welcome Senior Ecological Engineer Mark Bowen of Kleinschmidt Associates (Strasburg, PA), who will be presenting highlights from the Hemlock Farms Project, which integrates many different types of green stormwater infrastructure in a 4,500-acre residential development in the Pocono Mountains of Pennsylvania.

Green Stormwater Infrastructure (GSI), which uses vegetation and soil to manage stormwater where it falls, can mitigate the effects of urbanization, which include poor water quality, flooding, and sewer overflows.  Hemlock Farms is likely to be the largest privately-funded stormwater retrofit in the United States, featuring retentive grading, ponds with constructed wetland bottoms, step pools, vegetated swales, and native plantings.  Mark will discuss public outreach, which was a key component of this project, and how selling offsets for compliance with NPDES permits helped finance the project.

The presentation will include a discussion of current and proposed regulations and guidance on how they apply to a 4,500-acre Green Stormwater Infrastructure (GSI) Project in Pennsylvania.  This will include some calculation methods.  Mark will discuss innovations in design required to adapt standard GSI to the site as well as funding and cost challenges to maintaining GSI.


Local, state and federal government officials, engineers, public works directors, architects, consultants, planners, related non-profit organizations, and involved citizens.

Stormwater is a contributor to flooding, water degradation and groundwater issues in the state. Understanding stormwater management includes plants, soils and water, which will help floodplain managers, sewer system operators, water system operators, and municipal authorities develop budgets, perform planning, refine engineering and schedule maintenance personnel in communities of all sizes.


  1. Explore how Green Stormwater Infrastructure (GSI) can be adapted to different sites.
  2. Understand the direction proposed for stormwater management in PA and how current regulations and guidance can accommodate GSI.
  3. Understand funding options for stormwater management.
  4. Evaluate the complexity of stormwater management.

Kleinschmidt will provide a catered lunch for all attendees.
