Culverts

                            The culvert data were originally collected in the mid-2000s by road shop crews using a Trimble GPS collector. Data are updated as new culverts are installed or existing but unmapped culverts are discovered. Descriptive information about each culvert, including size, material, condition, and association with tide gates is included in the attributes.The “House_Numb” field is used if the feature is near a known street address. “Location” is used when descriptive information about the feature’s location may be useful, as in when the feature is not easily found. “Attention_” is marked “yes” if the feature appears to need some maintenance or repair. “Remarks” is used to add any important information unique to the feature. “Name_of_Sy” is used to identify those features that are part of a named drainage system – most are not. "Outfall" indicates whether the culvert outfalls to the beach. "Tidegate" indicates whether there is some type of tidegate on the culvert. "Contact Info" refers to who is responsible for the tidegate
                          

                            The culverts layer was created for the purposes of maintenance tracking, facility inventory, and general cartographic use.  The data are also used in drainage analysis and watershed mapping.  Last updated April 2015.
