At KPG, stormwater engineering is not merely an add-on service. For over 30 years we have worked directly with our clients to navigate the increasingly stringent environmental regulations governing stormwater management. We bring innovative and creative ideas that are appropriate to each project and are infused with current sustainable practices.

We are experts at balancing the challenges associated with stormwater projects. This includes creative solutions to limited available right of way, conflicting utilities, loss of on-street parking, and mature trees. We also prioritize the cost effectiveness of long-term maintenance to develop successful projects that are an asset to the community.
