The New Hampshire Erosion and Sediment Control Ordinance is a set of regulations designed to prevent and control soil erosion and sedimentation in the state. It is implemented to protect the environment, preserve natural resources, and ensure the long-term sustainability of construction and land development projects. Under this ordinance, various types of erosion and sediment control measures must be implemented during different phases of construction activities. These measures include the installation of erosion control barriers, sediment basins, silt fences, and erosion control blankets. Additionally, proper soil stabilization techniques such as hydro mulching and hydro seeding may be required. There are different types of erosion and sediment control ordinances in New Hampshire, depending on the specific region or municipality. Some examples include: 1. Municipal Erosion and Sediment Control Ordinances: These are enacted by individual cities or towns within New Hampshire to address local erosion and sediment control needs. They may have additional regulations and requirements specific to their area. 2. Statewide Erosion and Sediment Control Ordinance: This is a general ordinance implemented across the entire state of New Hampshire to establish baseline standards for erosion and sediment control. It applies to all construction projects regardless of their location. 3. Watershed-Specific Erosion and Sediment Control Ordinances: Certain watersheds in New Hampshire may have their own unique erosion and sediment control ordinances. These ordinances are tailored to the specific needs and characteristics of the watershed and aim to protect the water quality within those areas. Overall, the New Hampshire Erosion and Sediment Control Ordinance plays a crucial role in maintaining soil stability, preventing sediment runoff into water bodies, and preserving the state's ecosystems. Compliance with these regulations is essential for developers, contractors, and individuals engaging in land development or construction activities to minimize negative environmental impacts.
