Stormwater Permitting

Stormwater Permitting

Our experience in permitting is a cornerstone of our capabilities. Along with completing permit applications or Notices of Intent, Shield is capable of water quality modeling for Total Suspended Solids (TSS), metals, volatiles, and other industry benchmark standards.

In addition to testing, our multi-skilled staff is able to provide staff training, perform permit reviews, and prepare reports or educational programs for stormwater runoff and comprehensive stormwater management studies.

Stormwater Pollution Prevention Plan

Stormwater Pollution Prevention Plan

The EPA’s stormwater pollution prevention regulations provide a baseline for state governments to uphold in their new and existing construction projects and industrial activities. Having a proper Stormwater Pollution Prevention Plan (SWPPP) may help you avoid fines, prevent project setbacks caused by erosion, and help keep wildlife around your job site safe. Whether preventing future issues or performing corrective action, Shield’s stormwater pollution experts can help.

Erosion & Sedimentation Control Plans

Erosion & Sedimentation Control Plans

Failure to have proper stormwater management can lead to soil erosion that causes setbacks on your job site. Shield’s experts can help navigate NPDES, 401, and 404 permit applications and compliance, provide erosion and sedimentation control plans, and guide stream restoration.

Hydraulic Modeling

Hydraulic Modeling

Modern modeling technology is used to predict failures, achieve a proper design, and cost-effectively test stormwater solutions. Shield has a wide variety of experience in hydraulic modeling including:

  • Bridge Modeling
  • Culvert Modeling
  • Storm Drainage Modeling
  • Dam Breach Modeling
  • HEC-1, HEC-2, HEC-HMS, HEC-RAS, SCS-TR55, FlowMaster, Hydraflow Hydrographs
Stormwater Design & Rehabilitation

Stormwater Design & Rehabilitation

Proper planning is an integral part of creating a water-conscious design. Shield’s cutting-edge scientific tools and techniques help you design and engineer a successful solution to fit your project’s stormwater situation.

  • Watershed Studies
  • FEMA Applications and Map Revisions
  • Hydraulic Reports for Structures
  • Combined System Studies
  • Storm Sewer Design and Rehabilitation
  • Flood Control Inspections of Post-Construction
  • Stormwater Structures and BMPs
Stream Restoration

Stream Restoration

Restoration ranges from simple repairs and stabilization to more dynamic intervention such as the installation of stormwater management facilities like constructed wetlands. 


Our services strive to prevent erosion and flooding, defend the fidelity of bridges and roads, and protect valuable land and water supplies to provide safety and peace of mind for the community.

By identifying risks and their solutions, Shield’s staff is able to develop policies and compliance programs founded on regulatory research and case applicability. Site audits, inventories, process reviews, and waste stream analyses are a small handful of the tools that Shield utilizes.
