Community Technical Assistance Program

Spatial Analysis

CTAP currently has access to ArcGIS, ArcGIS Online, ESRI Network Analyst, and CommunityViz licenses that it can use to provide assistance, including:

Mapping and analysis support for long range planning documents, such as Growth Policies and Capital Improvements Plans
CTAP can assist communities with the development of maps that are typically included in Growth Policies, displaying existing ground conditions and analyzing available data to identify trends that may not be readily apparent from raw census-level data. CTAP can also help to develop maps that portray desired future conditions, including Future Land Use Maps, maps that display and project likely outcomes based on current or proposed development patterns, and maps that help to identify potential community needs and trends.

Mapping for regulatory planning documents, such as Zoning Ordinances
Jurisdictions wishing to amend or adopt Zoning Ordinances or other regulatory documents can ask CTAP to help them in the development of supporting maps. Maps can be developed at the local level and then digitized, to create a readable, accessible map.

Online, Interactive Mapping
Communities in the process of developing planning documents may wish to have maps available online to support their public participation efforts. CTAP can host community web mapping resources through its ArcGIS online account.

Spatial Analysis Including:  

Site Suitability
This type of analysis helps to answer questions such as: Where is the best place to locate a new shopping center? What is the highest and best use of a vacant parcel within a community? Would a particular site be appropriate for the development of housing?

Service Area Analysis 
This type of analysis looks at the broader impacts of existing or proposed services. Does the current fire station provide adequate response to outlying community members? Who would benefit from a new hospital placed in a particular location?

Land Use and Demographics Analysis
This type of analysis explores existing ground conditions, and draws conclusions from those conditions. What is the current mix of land use within the community? Is there enough affordable housing? Do seniors live disproportionately far away from necessary services? Is there land available for industrial development,that has access to necessary transportation infrastructure?

Growth and Buildout Projections
Communities can change over time. This type of analysis answers questions such as: If we approve a new large-scale residential development, what impact will that have on existing services? If the community continues as it has, how will the community likely grow over the next 20 years? If the community adopts or amends regulations, what are the possible consequences of those changes?

Transportation Corridor Modeling
This looks at the existing transportation infrastructure and how it plays into the community. Is the current transportation network sufficient to attract new industry? Is the current transportation network overbuilt? Could the community save money without losing capacity by changing the road maintenance schedule? How well served are existing land uses?

Walkability Analysis
How walkable is the current community? Can local children safely walk to school? Is biking feasible in the community? Are there sidewalks, and do they serve affordable housing?
