Title: Alpine Loop Development Potential

Geospatial_Data_Presentation_Form: map

Description:

Abstract:

The Alpine Loop Development Potential data set shows the risk of avalanche on lands along the Loop. This data set along with the Conservation Resource Value is used to determine the Landscape-Based Conservation Priorities.

Development potential combines general development constraints that detract from the "buildability" of a parcel. General development constraints included in the analysis are steep slopes, geologic hazards, avalanche hazard, proximity to existing roads (to access a property), floodplains, environmental constraints and wildfire hazard.

Purpose:

The Alpine Loop Spatial Analysis and Mapping Project inventoried natural and cultural resources and identified important areas where overlapping resources occur. The results from this project will provide an opportunity for area stakeholders - landowners, outdoor enthusiasts, surrounding communities, federal government agencies and local and national preservation groups - to come together to find solutions that maintain the Alpine Loop experience for future visitors and residents, while working within the framework of landowner objectives as well as local and federal government goals.

The Alpine Loop Spatial Analysis and Mapping Project analyzed the Alpine Loop landscape, considering important natural and cultural resources along with the likelihood of development based upon building constraints. The Project aims to provide a planning tool for area stakeholders as they consider the variety of land management options and the future of this magnificent region. The next logical step will be to craft solutions that work within the framework of landowner desires, local and federal government land management goals, and available financial and technical resources to manage the area in a way that preserves the Alpine Loop experience for future generations.

While the Alpine Loop lies within three counties - San Juan, Hinsdale and Ouray - the analytical work extended into a portion of San Miguel County. The resulting mapping and analyses will:

1. Create a spatial foundation to aid future projects in the Alpine Loop corridor;

2. Serve as a prioritization tool for evaluating the conservation potential of individual private parcels;

3. Provide the necessary framework for pursuing future funding opportunities.

Attribute:

Attribute_Label: Development potential grid cell value

Attribute_Definition:

The value provides an estimate of the development potential of a location based upon physical constraints at that locale. Development potential was normalized based on the number of constraints that were validly mapped at that locale (differentiating no hazard from no data). The normalized development potential had a potential range of 0 to 3 (since each constraints was typically classified in the 0 to 3 range). This normalized value was then "stretched" by a factor of ten and converted to integer.
