Stormwater

1. SUMMARIZE THE MEASURES FROM THE STORMWATER MANAGEMENT PLAN (“SWMP”) THAT WILL BE USED FOR PUBLIC EDUCATION AND OUTREACH:
The City of Washington will publish two articles per year in the local newspaper, develop and maintain an SWMP page on their website, implement and advertise a stormwater telephone hotline, meet with local educators and help them develop a curricula on stormwater quality issues and the SWMP, work with restaurant owners on the proper operation and method of grease traps, and provide public presentations on the SWMP.

2. SUMMARIZE THE MEASURES FROM THE SWMP THAT WILL BE USED FOR PUBLIC INVOLVEMENT AND PARTICIPATION:

The City will hold public meetings to present and discuss the progress of the SWMP, develop and work with a citizen’s advisory panel to monitor and update the SWMP, solicit and involve volunteer groups for training and community clean-up activities, and train volunteers for illicit discharge detection.

3. SUMMARIZE THE MEASURES FROM THE SWMP THAT WILL BE USED FOR ILLICIT DISCHARGE DETECTION AND ELIMINATION:

The City will conduct annual inspections of the open drainage system (1/4 of the system per year) to detect, identify, and eliminate illicit discharges, train volunteers and City employees to detect and report illicit discharges, update the stormwater collection system mapping, continue to provide and support used motor oil recycling, pursue opportunities for household hazardous waste collection events.

4. SUMMARIZE THE MEASURES FROM THE SWMP THAT WILL BE USED FOR CONSTRUCTION SITE STORM WATER RUNOFF CONTROL:

The City will develop and implement standard inspection and reporting procedures for construction site surveillance, inspect all sites over one acre for compliance with runoff and erosion control requirements, review and update existing ordinances as needed to require appropriate stormwater sediment and erosion control, and provide sanctions for non-compliance.

5. SUMMARIZE THE MEASURES FROM THE SWMP THAT WILL BE USED FOR POST- CONSTRUCTION STORM WATER MANAGEMENT:

The City will implement inspections of construction sites one year after completion of construction activities to ensure proper operation and maintenance of the stormwater systems, review and update existing ordinances on post-construction system maintenance and buffer and landscape requirements, promote the use of BMPs such as reduction of impervious areas, grassed swales, wet ponds, dry detention basins, etc., and implement a developer website to educate developers and designers on the City requirements.

6. SUMMARIZE THE MEASURES FROM THE SWMP THAT WILL BE USED FOR POLLUTION PREVENTION AND GOOD HOUSEKEEPING:

The City will develop pollution prevention plans for City facilities such as the public works garage, train City staff on proper pollution prevention and good housekeeping practices, continue street sweeping, and implement measures such as inlet cleaning to reduce sediment and debris entering streams, review and modify City practices such as salt spreading, herbicide/pesticide/fertilizer application, and train City construction crews on sediment and erosion control measures for City construction sites.

Public Education and Outreach on Storm Water Impacts

Trash Management

Description

Trash and floating debris in waterways have become  significant pollutants, especially in areas where a large volume of trash is generated in a concentrated area. Trash in waterbodies contributes to visual pollution and detracts from the aesthetic qualities of the landscape. It also poses a threat to wildlife and human health (e.g., choking hazards to wildlife and bacteria to humans). Additionally, trash and debris can clog the intake valves on boat engines, which results in expensive repairs.

Applicability

When developing control strategies for trash, municipalities should consider the following points:

  • Implement a control structure designed to target the most prevalent types of trash and identify the source or sources of the trash.
  • Evaluate the costs for each Control. Develop a budget that takes into consideration what services and facilities are already available and can be utilized at the lowest cost.
  • Regular cleaning and maintenance are necessary to prevent the accumulating trash at control structures from being hazardous itself.
  • Control strategies should not just transport trash to another waterbody, but should reduce the quantity of trash in the water as a whole.

Implementation

Citizen awareness is key to a successful trash management program, Citizens should be informed about the environmental consequences of littering, Pictures are especially effective at describing the problem.

Low-Impact Development

Description

Using low-impact development (LID) approaches for new development can help to achieve storm water pollution reduction goals. Through LID approaches, storm water runoff can be controlled while development objectives are achieved.

An important component of a municipal LID program is public outreach. The first step in achieving LID is to encourage developers to adopt such approaches. This is followed by the development and implementation of a program to ensure that design standards are met and that homeowners are adequately informed of their responsibilities. The latter should be the responsibility of the developer and homebuilder. This outreach takes the form of the developers communicating maintenance instructions and pollution prevention measures to the property  owners. The public outreach program informs property owners of their responsibilities to the environment. When successfully implemented, LID education and awareness programs accomplish the following:

  • Establish a marketing tool that allows developers to attract environmentally conscious buyers
  • Create more landscaped areas, enhancing the aesthetics of developed areas
  • Educate property owners on effective pollution prevention measures
  • Promote the proper maintenance of best management practice
  • Inform commercial property owners of potential cost savings from using LID approaches
