Sustain your infrastructure for maximum value.

Like all infrastructure, green infrastructure requires monitoring and maintenance in order to function properly over the long term. Officials, professionals, and staff need training. And engaging the community creates a sense of ownership and stewardship.

Operations and Maintenance

Maintenance varies for each type of green infrastructure practice and a specific maintenance plan should be tailored for each installation. Maintenance responsibilities, inspection frequency and costs should be evaluated during the design phase of each practice. In order to ensure the proper performance of the green infrastructure practice, maintenance plans should identify responsible parties over the lifetime of the practice and agreements should be put in place, as necessary, to ensure proper and regular maintenance.

Here are basic principles for good maintenance, with specific guidance documents and manuals from NJDEP, Rutgers and other experts. 

  • Keep soil free of compaction.
  • Control the occurrence of invasive species.
  • Revegetate bare areas (with the exception of constructed wetlands and wet ponds).
  • Provide easy access for inspection and routine maintenance.
  • Conduct annual inspections of all structural components (inlet pipe, discharge outfalls, valves and related operational appurtenances).
  • Clean out sediment traps and scour holes four times per year, and after all storms generating one inch or more of rainfall.
  • Inspect underdrains of applicable GI BMPs twice per year to ensure they are operational.
  • Inspect the planting bed at least twice per year for any evidence of pooling, bare vegetation and/or invasive species, to determine if the permeability of the bed has decreased.
  • Mowing is normally conducted once per year, usually in the fall, using lightweight equipment such as string trimmers, to prevent the compaction of soil.
  • Vegetation should not be cut any lower than six to eight inches above the ground. This avoids “scalping” the vegetation, leaves residual material that can filter pollutants even when the plants are not actively growing and helps maintain a seed stock.
  • Provide at least 85 percent of the area in vegetative cover. If bare areas exceed 50 percent, the GI BMP should replanted with the same plants stipulated in the original design and construction plan.
  • Inspect once a month and/or within 48 hours after a storm greater than 1.25 inches and note observations in a maintenance log to ensure proper actions are addressed should an issue arise during inspections.

Guidance Documents and Manuals:

  • Rutgers Cooperative Extension (RCE) Water Resources Program
    • Developed this presentation, which provides green infrastructure maintenance guidance.
  • Philadelphia Water Department
    • Developed this Maintenance Manual, which provides excellent guidance to the department and partnering organizations, including developers and design professionals.

Green Grounds & Maintenance Policy
Landscaping can be an integral part of a green infrastructure project, and Sustainable Jersey awards points for public plantings and maintenance with stormwater management in mind. The Green Grounds & Maintenance Policy must address the following topics: efficient landscape design; minimizing water consumption; recycled materials and composting; and integrated pest management.

Monitoring

The best way to track the performance, inspection and maintenance of GI BMPs is by keeping a log book. The log book need not be overly complicated, but it should include the following:

  • An overview of the GI BMP that provides a simple description of the BMP’s design. This can be supplemented with a simple schematic of the BMP or even a detailed as-built drawing.
  • Clear and concise schedule of inspections (typically once quarterly and following any storm event that generates at least one inch of precipitation).
  • Outline of the required/suggested maintenance equipment.
  • Inspection and maintenance checklist.
  • Simple reporting form.

The log book can be created in a digital format. This allows links to be provided to specific design features of the GI BMP and maintenance manuals, and to create and maintain a photographic record of the BMP condition and maintenance activities. The Connecticut Department of Energy and Environmental Protection has a simple but thorough maintenance checklist and form.

This e-learning tool developed by Rutgers Water Resources Program provides an introduction into inventorying and mapping your stormwater infrastructure. It also reviews a case study that highlights the benefits of GIS-based databases as an alternative to paper records for municipal stormwater infrastructure systems.

Community Engagement

Community engagement and education is key to promoting the adoption of green infrastructure. Local community leaders and residents play an important role in identifying water resources problems, such as areas that flood regularly, where sewers back up, and where sediment or trash is washing into waterways. Once engaged and educated, community members can become advocates for green infrastructure and encourage the municipality, businesses, schools, and neighbors to install it. Communities can become engaged through the creation of local groups that focus on stormwater issues, such as municipal action teams. Specific programming can also be used to engage residents and provide incentives to install GI. Here are some examples of community engagement programs.

Public Projects With Interpretive Signs

School Example: Dr. Michael Conti Public School #5, Jersey City, NJ

Project Description

In 2017, the Dr. Michael Conti School No. 5 broke ground on an innovative stormwater management project in partnership with the Jersey City Municipal Utilities Authority (JCMUA), the Rutgers Cooperative Extension Water Resources Program, Jersey City Board of Education, and Jersey City START (Stormwater Treatment and Resiliency Team). The project is, funded by the JCMUA through a New Jersey Environmental Infrastructure Trust low-interest loan. Downspout planter boxes, porous asphalt, and tree trenches provide storage for stormwater runoff, cleaning it and releasing it slowly into the sewer system to reduce localized flooding and combined sewer overflows. In addition, the downspout planter boxes provide ecological benefits, beautify the school, and provide an outdoor living lab for STEM education.

School Example: Elysian Fields Community Garden and Paterson Public School #5, Paterson, NJ

Project Description

At the Elysian Fields Community Garden behind Paterson Public School No. 5, the city transformed a once-vacant lot into a beautiful community garden. But the garden had no source of clean water for irrigation. In 2015, community members of Elysian Fields, the Paterson Public School No. 5, the Passaic Valley Sewerage Commission, and the Rutgers Cooperative Extension Water Resources Program partnered to install a rainwater harvesting system that provides access to water to the 37 families gardening in Elysian Fields. Passaic Valley Sewerage Commission funded the installation of a 2,500-gallon cistern and a pump to ensure the water reaches the garden. The unique partnership between Elysian Fields Community Garden and the private property owner made possible the rainwater harvesting system as well as the electrical connection that powers the pump.
