Wetland Delineation

ASTI performs field-based delineations to identify wetlands, streams, and other regulated water features in accordance with state and federal protocols. Our team prepares detailed maps and reports to support project design, permitting, and mitigation planning, ensuring regulatory clarity early in the development process.

Wetland Permitting

We manage all aspects of wetland and stream permitting, from application preparation and agency coordination to public notice and approval tracking. ASTI’s proactive approach reduces risk and ensures projects stay on schedule and in compliance with regulatory requirements.

Wetland Mitigation Design

Our team develops mitigation plans that restore or create wetland and stream systems, ensuring required functional lift and regulatory approval. Designs focus on ecological integrity, hydrologic stability, and long-term maintenance feasibility.
