service overview

how our Floodplain & Risk Management service helps you

Streamline helps communities, agencies, and developers navigate the complexities of floodplain management through a comprehensive suite of regulatory and technical services. We provide floodplain mapping, flood risk assessments, Floodplain Development Permits, CLOMRs, LOMRs, CLOMR-Fs, LOMR-Fs,
No-Rise Certifications, and supporting hydrologic and hydraulic analyses. By combining technical expertise with regulatory experience, we help clients minimize project risk, streamline approvals, maintain compliance with federal, state, and local requirements, and make informed decisions that support resilient development.

Floodplain Mapping

We develop accurate floodplain mapping and flood risk assessments to support planning, regulatory compliance, and resilient community development.

FEMA CLOMR/LOMR

We prepare and manage FEMA Conditional and Final Letters of Map Revision (CLOMRs and LOMRs) to support floodplain modifications and regulatory approvals.

Floodplain Development Permitting

We provide technical analyses and permitting support to help public and private projects comply with local, state, and federal floodplain development requirements.

Downstream Impact Analysis

We evaluate the downstream hydraulic impacts of proposed developments and infrastructure improvements to support safe design and regulatory compliance.

Benefit-Cost Analysis

(BCA) We develop FEMA-compliant Benefit-Cost Analyses that quantify project benefits and maximize competitiveness for state and federal funding programs.

Case Study

Judson Road & Lookout Road Drainage Improvements

Recurring flooding at the Judson Road and Lookout Road low-water crossings posed a significant risk to public safety, emergency access, and transportation reliability. The project required replacing aging drainage infrastructure while accommodating railroad constraints, minimizing impacts to surrounding development, reducing flood risk, and supporting state and federal grant funding initiatives.
