Expert Stormwater Planning, Engineering, and Asset Management
At Gradient, PLLC, we specialize in stormwater planning, engineering, and asset management solutions that ensure sustainability and compliance. From watershed planning to stormwater asset management, and design/construction of capital improvement projects, our experienced professionals leverage cutting-edge tools and techniques to deliver impactful results.
Comprehensive Stormwater Services
Stormwater Planning and Management
Our team excels in stormwater planning and design, developing solutions that range from small-scale drainage improvements to large-scale watershed flood improvement plans. We ensure compliance with regulatory standards and assist communities in securing grants for project implementation.
- Watershed planning studies.
- Flood improvement plans.
- Cost-effective, community-focused solutions for water quality improvement.
Our approach to stormwater engineering incorporates:
- Research and data analysis for informed decision-making.
- Evaluation and design of stormwater control measures (SCMs).
- Applying the latest design and modeling tools to solve complex problems.
- Thinking outside the box to develop innovative, site-specific solutions.
Enhancing Water Quality
Gradient prioritizes water quality management through:
- Monitoring plans, data collection, and regulatory reporting for compliance.
- Modeling tools to understand pollutant behavior and develop reduction strategies.
- Navigating water quality regulations such as nutrient rules and Total Maximum Daily Loads (TMDLs).
Our stormwater asset management services ensure long-term functionality and compliance. We provide:
- Inventories, inspections, and condition assessments of stormwater assets (pipes, structures, treatment systems aka (SCMs) stormwater control measures and (GSI) green stormwater infrastructure).
- Risk analysis and prioritization for repairs and rehabilitation of assets.
- Development of asset management plans, customized standard operating procedures (SOPs) and technical specifications for stormwater control measures (SCMs) maintenance.
Our continuous improvement approach follows the core principles of asset management that will help to decrease the life-cycle costs and extend the useful life of your assets.
Municipal Separate Storm Sewer System (MS4) Regulatory Compliance Support
Navigating MS4 regulations is easier with our expertise. We offer:
- Permit support (plan reviews, preparation, and submission of annual reports).
- Mock audits and compliance analysis to prepare for regulatory audits.
- Stormwater program development and public engagement.
- Code and ordinance updates for stormwater programs.
Our approach to managing small dams incorporates:
-
Research and analysis for informed decision-making by dam operators.
-
Development of Emergency Action Plans (EAPs).
-
Assistance with table-top exercises.
Stream Stabilization
Land development projects may require engineering stabilization of a receiving stream that is eroded. Similarly, critical utility (water/sewer) installation projects in urban areas often requires aerial crossing over a jurisdictional stream. Gradient team can assist you with floodplain analysis, permitting, and design of stream stabilization projects in urban areas. Our typical approach to these projects involves:
- Site reconnaissance
- Hydrologic and hydraulic analysis (using HEC-HMS, HEC-RAS 1-D or 2-D)
- Stream crossing stabilization design (engineered or natural)
- Floodplain analysis and permitting (No-Rise Certifications, LOMR, CLOMR)
- Coordination with regulatory and permitting agencies
Our Engineers can assist you through the whole process and guide your project to a successful outcome.
Gradient uses advanced tools like Personal Computer Stormwater Management Model (PCSWMM) and HEC-RAS 1-D/2-D, Infoworks ICM, Light Detection and Ranging (LiDAR) data, and Geographic Information System (GIS) mapping to identify flooding and pollution hotspots in watersheds and develop effective solutions. Our team integrates both water quantity and quality modeling to ensure compliance with state and federal standards, such as the United States Environmental Protection Agency (USEPA) 9-element planning criteria.
Stormwater Capital Improvement Projects
We’ve successfully delivered storm drainage system improvements, including a recent culvert replacement that significantly reduced flooding for a municipal client. Our cost-effective design incorporated a 36-inch diameter outfall to efficiently manage stormwater flow, helping create a safer environment for the community.
As part of our stormwater engineering services, we also offer:
-
Evaluation and design of stormwater control measures (SCMs) and green stormwater infrastructure (GSI) to treat urban stormwater runoff.
- Construction administration to ensure compliance and quality. Our experienced inspectors provide construction oversight on behalf of the owner to ensure the plans and specifications are being followed by the contractor.
Protecting Water Systems with Proactive Assessments
Gradient, PLLC provides comprehensive stormwater inspections to help municipalities, businesses, and developers maintain compliance with regulatory standards and optimize stormwater system performance. Our experts conduct detailed inspections of stormwater infrastructure, including drainage systems, retention ponds, and stormwater control measures (SCMs), identifying issues before they become costly problems. Through proactive assessments, data-driven analysis, and regulatory reporting, we help clients mitigate flooding risks, enhance water quality, and extend the lifespan of stormwater assets.
