Site Development
With an unparalleled understanding of sustainable site development, D&B can exceed client goals while working within the constraints of budgets, property limits, zoning and code requirements, permits, and site conditions. We have the team experienced in land development site plan design to properly determine the configuration of the site, parking, roads, sanitary sewer collection and disposal facilities, water distribution and stormwater systems, building locations, utility services and site amenities to provide fully functional and efficient sites; zoning and entitlements are also a core component of our site development services.
Stormwater Management
As on one of the biggest contributors to water pollution, stormwater runoff must be managed to ensure that public health remains protected for generations to come. With experience that includes working with United States Environmental Protection Agency (USEPA) and New York State Department of Environmental Conservation (NYSDEC), we provide stormwater management solutions that evaluate each project element to help clients develop and implement cost-effective, performance-driven stormwater management programs.
