NH Drinking Water Quality Buffer Model Ordinance Protecting Water Resources at the Local Level
Methods of Buffer Protection
Water quality buffers can incorporate landscape level characteristics that contribute to water quality impairment such as steep slopes, erodible soils, stormwater runoff, and non-point and point sources of pollution.
The model buffer ordinance seeks to recognize these landscape characteristics where they occur - not on all properties and not on all development sites. The goal is to prevent water quality impairment and minimize existing impairments when possible.
The guidance in this document provides an approach to protecting the long-term quality and availability of New Hampshire’s surface water being used as a source of drinking water by a public water system. The guidance considers the current literature involving the role of buffers in maintaining water quality as well as other factors including site specific conditions, and land use best management practices.
Protecting public and private drinking water resources is most often accomplished through the following approaches:
local water resource protection and conservation that engage community stakeholders and water users and promote best practices in water management, investments in protective measures, and sound land use planning and policies;
land use regulation and management focused on pollution prevention best practices and limiting development and impervious surfaces in drinking water supply watersheds;
land conservation practices focused on protecting source waters and their contributing drainage and recharge areas; and
application of best available science on water quality protection, drought, climate change, water conservation, and water resource and demand management.
