When the water's rising, we will help keep your feet dry.
LAN offers the complete spectrum of stormwater management services, including initial planning and feasibility studies, experienced design engineering and construction support, and permitting and regulatory compliance.
2-Dimensional (2D) Modeling
2D hydrodynamic modeling has become a powerful tool to investigate areas impacted by flooding during rainfall events. By modeling historic rainfall events, 2D modeling helps accurately demonstrate rainfall depth and flow direction. Our 2D modeling specialists apply practical modeling techniques to fully understand stormwater conveyance system performance during flood events, identify the root cause of flooding problems, develop solutions on localized and regional scales, and document improvement benefits.
Water Quality Management & Modeling
With more communities experiencing substantial population growth, urbanization, and aging infrastructure, receiving water bodies are becoming increasingly polluted by urban runoff and wastewater leaks. The LAN team has developed water quality tools to quantify the cost and effectiveness of proposed water quality improvement measures. Our water quality team can work directly with communities and agencies to address existing impairments, as well as guide future watershed planning to improve sustainability and quality of life.
Cooling water discharged from power plants and industrial facilities may have negative impacts on receiving water bodies and ecosystems. Our thermal modeling team has the tools and extensive experience to evaluate and address thermal discharge issues, as well as support the permitting process with regulatory agencies. We are knowledgeable of current and impending state and federal regulations, and can assist affected industries with technical support to meet or maintain compliance.
Municipal Separate Storm Sewer (MS4) Permitting
The Clean Water Act is the primary federal law that regulates water pollution to surface waters and requires most municipalities have an MS4 permit to regulate stormwater discharges. LAN can support a variety of compliance obligations, including:
- Permit application
- Storm Water Management Plan (SWMP) / Storm Water Pollution Prevention Plan (SWPPP) development
- Best Management Practice (BMP) creation and implementation
We are knowledgeable of existing and emerging stormwater quality regulations and have a proven track record of keeping clients in compliance.
Community Rating System (CRS)
CRS is a flood insurance premium discount program for communities in the National Flood Insurance Program (NFIP) to adopt and enforce higher standards for better floodplain management. LAN provides assistance in all areas of the CRS process, including new CRS applications, reverification, program optimization, and individual activities within the CRS program.
Stormwater Management Leadership
Janine Ellington, CFM
CRS/Floodplain Programs Manager
Janine Ellington has extensive experience assisting communities with the Community Rating System (CRS) program. Her unique skill sets include complete implementation of the program, and working with communities in Texas, Oklahoma, Arkansas, Louisiana, and New Mexico to initiate the CRS program, as well as maintain or improve CRS ratings.
As a former ISO/CRS Specialist, Janine understands how to efficiently navigate the process of joining CRS, as well as the three to five-year reverification process through the updated 2013 CRS Coordinator's Manual. She has a full understanding of newly available credit opportunities and obtaining credits with a community's current activities.
Additionally, Janine has 13 years of experience as a Floodplain Administrator for local government. As a local government official, she gained extensive knowledge in the minimum requirements of the NFIP, permitting, as well as flood recovery and grant submittals for floodplain management.
