Stormwater design and permitting in Maine is a constantly evolving process. The recent revision to Chapter 500 by Maine DEP is a perfect example of this. Empirical data supports the concept of increasing storm intensities. With recent revisions to Chapter 500, it is apparent that the State of Maine is adapting its regulations to ensure stormwater facilities can accommodate additional volume and peak flows.
Significant storm events can handcuff communities that are not prepared. Since our established in 1978 BH2M has supported developers, institutions, and municipalities with detailed stormwater analysis including watershed delineation, water quality analysis, BMP design, and hydraulic and hydrologic studies. Our staff is highly qualified in several proprietary software packages that aid in estimating volume of runoff as well as peak flow rates. We also excel at balancing technical analysis with a practical approach that relies on field review of existing conditions and interviews with stakeholders. Understanding historic impacts of existing storm drainage systems are a significant aid to our engineers. Balancing a sound technical approach with detailed field review enables us to provide practical solutions to common stormwater challenges.
BH2M has provided stormwater and erosion control design and permitting for a variety of municipal and private sector projects. Our experience includes:
