A Case for a Formal Sturctue STEERING COMMITTEE STRUCTURE
Is there a need to be formal? Decisions impacting numerous agencies Decisions will have a cascading effect Helps with documentation for future reference Its not PART s project Credibility outside the region Maybe political landmines ahead

Permanent Open Space No Development Potential Office Education 2 = See the Piedmont Triad Region CommunityViz Model Guidebook for a list of community types recommended for the region (a expanded list compared to the Piedmont Together project). Committed Development Committed Development Inventory University/College Piedmont-Triad CommunityViz Model v. 1.0 3 = A development lookup table for the Piedmont Triad Region CommunityViz Model should contain the following information for each community type category and jurisdiction: county, jurisdiction code, average FAR, average density, average density by watershed protection category, percent residential development, percent non-residential development, percent single family development, percent multifamily development, percent low-traffic industrial development, percent high-traffic industrial development, percent low-traffic retail development, percent high-traffic retail development, percent low-traffic service development, percent high-traffic service development, and percent government office development. 4 = Residential and employment categories used in CommunityViz match those used in the Piedmont Triad Regional (Travel Demand) Model. Single-family and multi-family dwelling units are later combined into households for the PTRM. 4 = An allowance for on-site infrastructure needed to serve new development (e.g., streets, storm water ponds, etc.). Applied to all grid cells in the region not yet developed. Reported as the percentage of a parcel remaining for development after the removal of areas identified for supporting infrastructure.
