Abstract:
This layer represents the areas identified as Constrained and Limited Constrained Slopes. This is a subset of slope mapping which constitues the Steep Slope Protection Area in the Highlands Region showing areas that are a minimum of 5,000 square feet for any combination of the following categories of steep slopes:
Severely Constrained Slopes:
All lands with slopes of 20% or greater and lands within Riparian Areas with slopes of 10% and greater
Moderately Constrained Slopes:
All non-Riparian Area lands having a slope of 15% to less than 20% which are forested
Constrained Slopes:
All non-Riparian Area lands having a slope of 15% to less than 20% which are non-forested with one or more of the following characteristics: a) highly susceptible to erosion; b) shallow depth to bedrock; or c) a Soil Capability Class indicative of wet or stony soils.
Limited Constrained Slopes:
All non-Riparian Area lands having a slope of 15% to less than 20%, which are non-forested, are not highly susceptible to erosion, and do not have a shallow depth to bedrock or a Soil Capability Class indicative of wet or stony soils.

Steep slopes within the Highlands Region play an important ecological, recreational, scenic, and functional role. Steep slopes and rocky ridgelines provide specialized habitats that are home to rare plant and animal species. Areas of steep slope provide popular recreational opportunities including hiking, climbing, and wildlife observation. Ridgelines, hillsides, and steep slopes provide scenic views and vistas, which contribute to the rural character of the Highlands Region and help to define the landscape. Disturbance of areas containing steep slopes can trigger erosion and sedimentation, resulting in the loss of topsoil. Silting of wetlands, lakes, ponds, and streams damages and degrades wetland and aquatic habitats, especially trout streams that are found throughout the Highlands and receive the State’s highest water quality protections. Steep slope disturbance can also result in the loss of habitat quality, degradation of surface water quality, silting of wetlands, and alteration of drainage patterns. These processes, when severe, can also result in land slumping and landslides that can damage both developed property and ecosystems. The severity and extent of slopes, soil characteristics, and land cover all affect the potential for damages from the disturbance of steep slopes. The identification and classification of steep slopes is important in order to effectively manage critical natural resources in the Highlands Region.
Purpose:
To develop, maintain, and improve a mapped inventory of steep slope areas in the Highlands Region using LiDAR derived elevation data and the most up to date Land-Use/Land-Cover data.
