HomeWhat We DoAdvocacy


A significant portion of our work is advocating for policies that advance the green stormwater infrastructure industry, including driving market demand for nature-based stormwater management and creating a navigable regulatory environment for local businesses in the GSI industry.

We are proactive and responsive to relevant agencies and stakeholders on topics that impact the growth of the GSI industry and its role in shifting the economic ecosystem towards equity and climate resilience.

We are a trusted voice in the growth of the GSI industry and our many research contributions have been used locally and nationally to demonstrate the necessity to prioritize green infrastructure solutions.

Comment Letter on July 2015 Stormwater Regulatory Update (February – September 2015)

In advance of the Stormwater Regulatory Update, we, along with our friends at NRDC and PennFuture, sent a letter to PWD offering our support on certain aspects of the proposed changes, and offered comments and concerns about others. Read the summary of PWD’s response to us from September 2015 – via in person conversations and written replies. We note what we heard the Department can currently do, what we heard is the intent of certain aspects of the Guidance Manual, and what we heard might be premature to do at this time. As always, we appreciate PWD’s communication with us, and look forward to continuing the dialogue with them to support progress in these and other areas. Read the Letter
