Using the Maintenance Plan Templates for Stormwater <br /> Treatment Measures <br /> The New Development Subcommittee (NDS) of the Clean Water Program has prepared <br /> templates that project applicants may use to prepare maintenance plans for the following <br /> stormwater treatment measures: <br /> 9 Bioretention' areas, <br /> ® Flow-through planters, <br /> ® Tree well filters. <br /> Infiltration trenches, <br /> Extended detention basins, <br /> 8 Pervious paving, and _ <br /> Media filters. <br /> These are treatment measures for which technical guidance has been provided in Chapter <br /> 6 of the Clean Water Program's C.3 Stormwater Technical Guidance, which may be <br /> downloaded from cleanwaterprogram.org (click on "for businesses,"then"New <br /> Development"). In some cases, a treatment measure may be sized to function as both a <br /> treatment and hydromodifi cation management (HM) measure. as described in Chapter 7 <br /> of the Clean Water Procram's C.3 Technical Guidance. If your project includes <br /> treatment and/or HM measures that are not listed above, but have been approved by the <br /> municipality, you may customize one of the maintenance plan templates with information <br /> specific to your treatment/HM measure(s). <br /> Microsoft Word documents of the maintenance plan templates may be downloaded from <br /> the above link to the Clean Water Program's New Development webpaoe. When using a <br /> template to prepare your maintenance plan, please insert project-specific information <br /> where you find prompts such as the following: Terreno West 140th LLC <br /> You will need to attach to your maintenance plan a <br /> legible, letter-size ($.5-by-I l-inch) site plan showing the locations) of the treatment/EM <br /> measure(s). Also, be sure to contact the municipality to learn about any requirements <br /> specific to the local jurisdiction. Agency contact information is provided inside the front <br /> cover of the C.3 Technical Guidance. <br /> A bioretention area that is unlined and has a raised underdrain in the underlying rock layer to promote <br /> infiltration,as shown in Section 6.1 of the C.3 Technical Guidance, may also be called a"bioinfiltration <br /> area" <br />
