Preparing For Your Storm Drain Marking Event Preparing for a Storm Drain Marking Event is a preparation checklist with more detailed information. Save the Bay’s Storm Drain Marking Program can offer assistance with event planning, volunteer recruitment, and project cost. Contact your local stormwater coordinator for permission and to select a neighborhood in which to do the storm drain marking. Obtain a map of the drains you plan to mark from your Town’s Department of Public Works or visually locate the storm drains in your selected area. Be sure to have enough maps available for all of your volunteers. Das Manufacturing is a sample vendor of storm drain markers, which you will need for your event. They usually cost between $150.00-$450.00, depending on size, quality, and message. Choose a rain date. Temperatures must be above 40 degrees F and the pavement must be completely dry in order for the markers to stick properly. Use a press release to publicize your event—the more you can educate local residents the better! Send out about a week in advance to local newspapers and online blogs, calendars, etc. Submit an Op-ed piece to your local newspaper.
