Runoff and flooding can result in accirents, pollution, property loss, and public health issues. When we’re planning for developments or designing new highways and roadways, we must consider what happens when it rains — from a simple shower to a torrential downpour, that water needs to be properly drained and diverted.
Ephrata Township has been very pleased with RETTEW’s MS4 and stormwater planning services. Their assistance for this very complex program has been a tremendous asset.
RETTEW has more than 45 years of experience providing stormwater management solutions in the public and private sectors. Our team of land and community planners, hydrologists, and geologists have extensive experience in stormwater testing, design, zoning, land development regulations, permitting, and erosion control. We help our clients develop and implement regulatory-compliant, cost-effective, and sustainable stormwater management plans that aren’t just beneficial today — but also well into the future. Our straightforward approach allows for shorter project timelines. We’re flexible and keep our clients’ budgets in mind — our recommendations range from innovative to minimalist. Additionally, we work with other RETTEW teams to address stormwater concerns in various land development and geological projects.
An MS4 program.
The U.S. Environmental Protection Agency (EPA) and many state agencies require local communities to adopt best practices in stormwater management. The EPA created the MS4 program, which requires municipalities to implement a plan that minimizes the impacts of runoff. MS4s—or municipal separate storm sewer systems — are comprised of curbs, gutters, ditches, pipes, drains, swales, rain gardens, and other naturally occurring and manmade channels. In many states, permitting for development projects, as well as municipal operations, require MS4 compliance — and RETTEW has an in-house specialist in this area.

RETTEW is an approved National Fish and Wildlife Foundation (NFWF) Technical Assistance Provider, helping preserve and protect our nation’s wildlife habitats, species, and ecosystems.
Proper stormwater management reduces flooding and pollution and it positively impacts our natural ecosystems, wildlife, and well-being of our communities. We must all adhere to best practices, and municipalities are tasked with educating communities to keep waterways clear of polluted stormwater. Best practices in stormwater management contribute to pleasing aesthetics in our communities, such as adding green spaces or creating functioning water features.
