The Methodology: Where Projects Meet Location PrerequisitesThe Methodology: Where Projects Meet Location Prerequisites

1. Identify and composite existing and officially planned water and wastewater serviceareas.

2. Exclude surface waters, wetlands, riparian areas, and their buffers from thecomposited utility service areas.

3. Exclude prime, unique, and important soils from the utility service areas.

4. Exclude imperiled species habitat, ecological communities, and their buffers fromthe service areas.

5. Exclude floodplains from the service areas.

6. In the remaining utility service areas, delineate the four allowed ND site types: Infill sites. High frequency transit service corridors. Diverse use neighborhoods. Low VMT traffic analysis zones.

Data Requirements for the MethodData Requirements for the Method

Required Areas

Water and wastewater service areas:

Water and wastewater service areas operated by municipal utilities and special service districts.

Urban growth boundaries (if functionally and legally equivalent to water/wastewater service areas).

Excluded Areas

Imperiled habitat areas:

Federal and state endangered species habitat, and federal habitat conservation plan boundaries.

NatureServe G1 and G2 habitat.

Natural Heritage Program imperiled species survey boundaries.

Wetlands and water bodies:

Surface water bodies.

NWI wetlands and riparian areas.

Prime/unique soils:

NRCS soil surveys (prime/unique/state significance).

Floodplains:

FEMA 100-year floodplain.

Required Site Types

Adequate transit service areas:

Transit routes with stops and peak hour headways.

Complete neighborhoods:

Parcels or points attributed with NAICS business types, civic facilities, and schools for “diverse uses”

defined in the rating system.

Below average VMT traffic analysis zones:

TAZs attributed with per capita VMT.

Previously developed, infill, and adjacent areas:

Parcels attributed with existing land-use.
