A drainage easement in New Hampshire refers to a legal agreement between a property owner and a municipality or neighboring property owner, permitting the use or access to a specific portion of the property solely for the purpose of water drainage. It ensures the unobstructed flow of stormwater runoff or surface water to prevent flooding and property damage. Drainage easements are established to maintain the proper function of drainage systems and related infrastructures. In New Hampshire, there are several types of drainage easements commonly observed: 1. Surface Water Easement: This type of easement allows the flow of surface water across one property to another, ensuring the natural drainage pattern is maintained. It allows for rainwater or melted snow to run off the surface normally and prevents water accumulation. 2. Stormwater Easement: A stormwater easement is utilized for managing excess rainwater that can result from heavy rainfall or storms. This easement allows water to be collected, channeled, or stored on one property for a specific purpose, such as stormwater management ponds or detention basins. 3. Grading or Scale Easement: This type of easement permits the construction and maintenance of graded areas or sales on a property. It ensures the proper shaping and sloping of land to facilitate drainage by directing water away from buildings or low-lying areas. 4. Culvert or Pipeline Easement: Culvert or pipeline easements establish the right to place and maintain drainage structures like culverts or underground pipes on a property. These structures enable the flow of water across or under the property while minimizing potential disruptions to the land. New Hampshire's drainage easements are crucial for maintaining an efficient and sustainable drainage system. Property owners should be aware of any existing easements on their land before initiating construction or altering natural drainage patterns. Local government agencies or legal experts can provide guidance on understanding and preserving the rights and responsibilities associated with drainage easements in New Hampshire.
