Environmental

Can environmental sensitivity and economic sensibility co-exist? Which is more important: salmon...or spreadsheets? Are words like "protection" and "profit" on opposite ends of the spectrum?

At LeRoy Surveyors & Engineers, we believe good land development benefits many stakeholders. Well-managed development design and skilled environmental engineering preserve the beauty and amenities of our region, and promotes healthy, strong businesses. LSE Inc. works with municipalities, developers and private parties to maximize land use and promote the bottom line...wisely.

If you're interested in agile environmental engineering--work that is skilled, beautiful and makes good business sense--please contact the LSE Inc. office to schedule an appointment or phone consultation. Our firm has close to 50 years of successful projects in the Pacific Northwest. This, along with our extensive networks in the private and public sector, gives us unmatched strength in the area of environmental engineering. We present a balanced approach that maximizes investments, builds value and respects natural resources.
