Water Resource & Stormwater Management

Pre-application Data Collection & Site Characterization

→ We compile existing hydrologic, topographic, and land-use data from GIS, LiDAR, soil surveys, and past reports. This phase defines drainage basins, identifies critical inflows and outflows, and flags regulatory constraints such as floodways or protected wetlands.

Stormwater Management Plan (SWMP) Development & BMP Design

→ We build hydrologic and hydraulic models to size ponds, swales, and green infrastructure. Our SWMP outlines treatment trains—sediment traps, bioretention areas, permeable pavements—and details inspection, maintenance schedules, and conditional monitoring to meet NPDES or local permits.

Watershed-Scale Nutrient Loading, Erosion Control, & Flood Mitigation

→ Using watershed modeling tools, we quantify pollutant loads from upstream land uses, pinpoint erosion hotspots, and simulate peak flows under design storms. Our recommendations range from riparian buffers and vegetated filter strips to grade-control structures that reduce sediment transport and downstream flooding.

Floodplain Analysis and FEMA Map Revisions

→ We perform HEC-RAS or similar modeling to redefine base flood elevations and floodplain extents. By preparing Letter of Map Revision (LOMR) or physical map revisions packages, we help clients secure reduced insurance rates, correct parcel risk profiles, and design flood-resilient infrastructure.

What We Do:

Water Supply Evaluations and Reservoir/Site Selection

→ Technical studies include aquifer testing, sustainable-yield modeling, and water-budget analyses. We match projected demand with source reliability, recommending reservoir or detention-basin locations that balance storage needs with ecological constraints and shoreline stabilization requirements.

Permitting, Implementation Support, and Adaptive Management

→ From pre-application meetings through permit renewals, we liaise with agencies to track conditions and submittals. During construction, we oversee BMP installation, verify performance via field inspections and sampling, then adjust practices as needed to sustain long-term compliance and water-quality goals.

Additional Insights

    • Typical SWMP permitting takes 8–12 weeks; complex watershed or floodplain studies may span 4–6 months.

    • Early coordination with local stormwater and water-management districts often uncovers design efficiencies and avoids costly redesigns.

    • Integrating green-infrastructure elements can reduce pollutant loads and offer community amenities like shaded trails or rain gardens.

    • Remote sensing (drone imagery, multispectral analysis) accelerates erosion mapping and post-construction monitoring.

    • Adaptive management plans tied to performance metrics ensure continuous improvement as climate patterns and regulations evolve.
