Conducting a Shoreline Survey A shoreline survey is a comprehensive examination of all coastal property for the purposes of identifying pollution sources that may be impacting coastal water quality in beach management areas. Background information used to conduct surveys (i.e. topographic and tax maps indicating new developments) should be updated every two years. Depending on the amount and type of change, certain areas may need to be re-surveyed or added to the existing report. Community members can assist with this process either by doing preliminary work, and/or assisting with the fieldwork. To conduct a shoreline survey, much preliminary information needs to be collected and organized prior to doing the field work. Tax maps, available from town offices, must be collected for each town involved in the survey. Topographic maps (7.5 minute USGS maps) must be enlarged on a copying machine and focused on target areas. The maps should be numbered and compiled so that they can be cross-referenced with tax maps and field sheets. Other information to be collected prior to a survey includes any information about public sewer systems, a list of licensed overboard discharges from the Department of Environmental Protection (DEP), information about agricultural (livestock) development, marina or other high boat use areas, and wildlife and recreational areas. This information will assist in collecting field data and in writing the sanitary survey. The survey itself involves driving house to house (or in densely populated areas, walking house to house) and interviewing landowners about their septic system. All data concerning the property needs to be recorded on field sheets. This process can take some time, especially when you are first learning how to conduct a survey. The survey also involves visually inspecting the septic area and looking for pipes and flowing water that might be pollution sources. These sources should be noted and a water sample should be tak
