From park planning to parking lots, and from running tracks to rain gardens, we design a spectrum of projects which help to harmonize the built and natural environment.

Scope of Services

Site Planning

Our site design experience includes all aspects of planning and implementation for residential, commercial, institutional, and educational clients; sports facilities; recreational facilities; subdivisions; campus planning; and landscape design.

Property Analysis for Site Selection

Every site is different, even two sites which are adjacent to one another. A thorough analysis must be done to determine not just what is seen, but that which is unseen, such as bedrock elevation or underground utilities.

Site Plan Reviews with Municipal Planning Boards and Other Governing Agencies

Many projects have design features which require approval from local planning agencies. We have considerable experience with planning board review, which facilitates the approval process for our clients.


An important aspect of site design is analyzing hydrology. When construction adds impervious materials to a drainage area, it changes the intensity of storm flows. This increase in storm water velocity during even an average rainfall can cause flooding, stream scouring, erosion problems, and soil loss. Hydrology studies are done for large-scale sites, such as campuses, as well as one-acre home sites. The intent is to design elements for the proposed construction that reduce the peak flows to what they were prior to construction. Some studies are done to evaluate existing sites that have drainage problems and design ways to control the storm runoff and provide good water quality.
