How effectively we manage, treat, and use stormwater as a resource is one of the most critical issues facing growing human populations in increasingly developed landscapes. Herrera designs stormwater conveyance, treatment and flow control at scales from site to regional and in settings including high use industrial sites, urban developments, neighborhoods, and sensitive ecological sites. Our services include hydraulic and hydrologic modeling, master planning, development of plans, specifications, and cost estimates (PS&E), and construction oversight. We are national experts in green stormwater infrastructure/low impact development, and our engineers collaborate with our scientists on cutting edge research and development to improve performance of GSI facilities, through development of improved bioretention media blends. In sensitive ecological settings, our geomorphologists, ecologists, and landscape architects work with our clients to design stormwater facilities that enhance habitat and manage stormwater.
