LeRoy Surveyors & Engineers, Inc. (LS&E) is committed to innovative land development practices. We believe Low Impact Development (LID) holds great potential benefits for developers, municipalities and the community. LID can save you money—and create more pleasing site designs.

LS&E is one of the leading engineering companies in the Northwest pioneering the research and implementation of LID practices. We have experience with Low Impact Development projects ranging from roads, subdivisions, porous pavement, pervious concrete and asphalt, bioretention, public works projects, native plant restoration, soil preservation and more.

If you have questions about LID or want to see if it might be beneficial and feasible for your needs, we invite you to contact Damon DeRosa, our lead LID staff member. Damon and our civil engineering staff have extensive experience with residential and commercial LID projects, along with municipal regulations regarding LID. Damon can be reached at our office by phone at (253) 848-6608 ext. 102, or by email at DDeRosa@lseinc.com.

WHAT IS LID?

Low Impact Development is an innovative approach to site development and stormwater management.

It combines cost effective practices, ecologically-friendly techniques and design enhancements for better land, water and air quality.

THE LID APPROACH

Low Impact Development is a balanced approach. It focusing on integrated site design and preservation of existing natural systems.

LID works well for many stakeholders: developers, municipalities and consumers.

BENEFITS FOR DEVELOPERS, MUNICIPALITIES AND COMMUNITIES

  • Preserving open space, native plants and undisturbed land.
  • Better stormwater management at the source. Lessening runoff, providing natural areas of absorption and reducing impermeable surfaces.
  • More pleasing neighborhood designs. Higher value for homes and a more livable community.
  • Ability to use wetlands/marginal land for bioretention.
  • Saves money. Less traditional infrastructure (vaults, ponds, etc.) often results in lower development costs.
  • More buildable land. Reduced pond and stormwater treatment areas.
  • Using innovative techniques for infrastructure (streets, curbs, lots, gutters, sidewalks, landscaping).
  • Reduces flooding, stream damage, water quality issues and erosion.
