Collection, Conveyance & Storage

As a community continues to develop, additional demands are placed on its storm water conveyance systems because of increased runoff from impervious surfaces.

A storm water system usually has several components that can include catch basins, storm sewers, creeks, storm water detention ponds, lift stations, force mains, ditches, and drainage features to accommodate storm water runoff.

Consequently, improving storm water management is often one of the largest undertakings a community faces.

 

Services

Jones & Henry can assist your community in improving all aspects of a storm water drainage system including:

  • Developing a Master Plan for system improvement.
  • Developing hydrologic/hydraulic models of the system to assess system deficiency and propose improvements.
  • Storm and sanitary sewer separation.
  • Design of storm sewers, culverts, and inlet structures.
  • Design of lift stations and force mains.
  • Design of detention ponds.
  • Oversight of construction.

Quality

Jones & Henry has assisted many communities with their storm water management programs, from the design of new conveyance and storage systems, to compliance with recent federal and state storm water quality standards and regulations.

We can help you develop and implement a storm water management program. Our capabilities include:

  • Developing a plan with measurable goals.
  • Mapping the storm water system.
  • Developing a public education and participation program.
  • Identifying storm water sampling sites.
  • Identifying funding sources for programs, including storm water utilities.
  • Developing strategies to achieve compliance that include both structural and non-structural approaches.
  • Designing required structural Best Management Practices (BMPs).
  • Developing a Soil Erosion and Sediment Control Plan.
  • Developing procedures for construction site inspection of storm water control measures.
  • Participate in public meetings to discuss the technical aspects of the program and requirements.
  • Prepare handouts or brochures describing federal and state regulations and requirements.
  • Locate illicit discharges.
  • Provide language to a community’s legal counsel for the development of a storm sewer-use ordinance.

Utility Development & Management

Jones & Henry is a leader in working with communities for their storm water initiatives and partner with communities of any size to develop and manage storm water utilities. A storm water utility is similar to a sewer or water utility, and it provides a service to the public and is financed through the regular billing of customers through user charges.

 

Process

When a community is considering developing a storm water utility, we will first help you to:

  • Identify current or existing storm water costs.
  • Estimate future costs and needs from a Comprehensive Storm water Master Plan.

Next, we will review the available options for your storm water utility (Flat Rate, Hydrologic Response Formula, and Equivalent Residential Unit, or ERU) to determine which option is best for your community.


Storage

Jones & Henry has performed large storm water storage studies which analyze the rainfall/runoff characteristics for watersheds up to 6,500 acres.

In order to alleviate downstream flooding, our firm makes various recommendations leading to the designs of retention/detention basins with overflow weirs, underground storage, existing weir structure modifications, and recommendations for the removal of repeatedly flooded structures.

 

Services

Jones & Henry has considerable experience with these types of projects and has assisted clients with the development of:

  • Site maps.
  • Estimates of impervious surfaces and total area drained by each outfall.
  • Designs of storm water retention basins based upon pre- vs. post-development conditions.
  • Stage-storage relationships utilizing computer modeling, Storm water Management Model (SWMM) and dynamic profiling.
  • Water quality analyses.
  • Quantitative data based on samples collected during storm events for required parameters.
