Utility easements. Utility easements along property lines or elsewhere for public purposes may be required. Such easements shall be at least 20 feet wide for one utility and five additional feet for each additional utility.

Conservation easements. Conservation easements and flood plains shall be indicated on the preliminary and final plats and shown in such a manner that their boundaries can be accurately determined. The removal of trees and ground cover shall be prohibited in such easements except for the following purposes: the removal of dead or diseased trees, limited thinning of trees and brush to encourage the most desirable growth, the removal of trees to allow for structures designed to impound water or convey stormwater, the removal of trees in areas to be flooded in the creation of ponds and lakes and the installation and maintenance of utilities.

Monuments. The boundary line of any easement shall be monumented at its intersection with all existing or proposed street lines, except when a lot line forms the side or centerline of the easement.

Drainage. Whenever the internal grading of a lot is part of the design of the drainage of stormwater system, as by swale, berm or other topographic feature designed to intercept or direct water, the same shall be designated as an easement on the map to be filed, or shall be dedicated by recorded instrument, in such a way as to give notice to future owners of said property and to ensure continued maintenance of such drainage feature. The recorded instrument or filed map shall contain a metes-and-bounds description of the easement, as well as an outline of the rights of the grantee in such easement, including but not limited to construction, reconstruction, replacement, repair, maintenance and enlargement of the facilities within the easement.
