Shelbyville, KY Stormwater Best Management Practices

1 5. Detention/retention volumes in the floodplain buffer shall count as fill if applied in a manner where off site floodplain storage volume is lost. 1.7 Residential and Home Owner Pollution Control Citizens of Shelbyville, also hold a stake in the maintenance and improvement of water quality in the community. If residents and property owners would take measures to minimize their impact in their surrounding environment, pollution can be greatly reduced. Residential and Homeowner BMPs (RHPs) describe methods that individuals can use and employ throughout their community to make ditches, streams and receiving waters safe. The pollutants that they discharge (most of the time unknowingly) can be reduced simply through education. Information on do s and don ts on chemical treatments (fertilizers, herbicides, insecticides, etc.) and disposal of other hazardous wastes (use of detergents into streams, or dumping petroleum based products into stormwater appurtenances such as catch basins) are just two examples on how to improve the water quality in a community. The City of Shelbyville should raise awareness of these BMPs to homeowners and residents via billings or community outreach programs and schools. 1.8 How to Use this Manual On the opposite page, please find a sample BMP Fact Sheet. This sample helps illustrate and explain the components that make up a fact sheet. Please note that some of the metrics used for the EPP and SMP section were not applicable to other sections and as such are not included. On the pages following the example please find a summary of the BMPs described in this manual. The summary tables should make it easy for the reader to quickly reference information such as symbols, cost and pollutants targeted by these BMPs. 1-33

This may include design parameters, structural check-ups, or structural inspection after significant rain events SMP-01 CD Target Pollutants 8 Significant Partial Low or Unknown Sediment Heavy Metals Nutrients Oxygen Demanding Substances Toxic Materials Oil& Grease Bacteria & Viruses Floatable Materials Construction Waste This section provides a general overview of the BMP activity and introduces common niches where it can be applied. Suitable applications direct the user to the general design limitations and site compatibility for the BMP activity. This section targets situations where the BMP activity could be most effective, and points out situations where the activity should not me implemented. The approach is a suggested plan of action for implementing the BMP activity. This includes specific planning considerations respective to the type of materials, construction planning, and suggests BMPs to install in series in order to maximize benefits. This section provides guidance to design considerations when constructing the BMP, and often references a sample drawing. Although maintenance is often needed after a significant rain event, this section gives detailed guidance to users for the frequency of maintenance specific to each BMP design. Here, the user can find recommended maintenance techniques, frequency of in-active inspection checks, and key areas to maintain in order to maximize the design life of the BMP. Legend 1.
