| Abstract: The High-quality Stream Watersheds dataset was created to define areas within the New Hampshire Coastal Watersheds with potentially high water-quality streams. Watershed boundaries are based on the USGS SPARROW water quality model. The definition for each tier is as listed below: Tier 1: Population Density <20 persons per sq mile, <1% of the area is developed, and <5% of the landuse is agriculture Tier 2: Population Density <36 persons per sq miles, <2% of the area is developed, and < 5% of the landuse is agriculture. Tier 3: Population Density is <64 persons per sq mile, <3% of the area is developed, and <5% of the landuse is agriculture. Tier 4: Population Density is <90 persons per sq mile, <3% of the area is developed, and < 5% of the landuse is agriculture. A complete description of the dataset may be found in The Land Conservation Plan for New Hampshire's Coastal Watersheds (section III) or in the excerpt "Coastal_Plan-App_D-2-Freshwater.pdf". | |
