Does the alternative divide or isolate a neighborhood or community2? (Is the neighborhood or comm nit di ided into 2

Yes Eliminate from further evaluation

No Continue for further evaluationneighborhood or community divided into 2 or more sections?  Are any sections isolated from community services?)

1Clear zone requirements in accordance with expansion/operational initiatives presented in CIRA’s masterplan.2According to the IDOT Community Impact Assessment Manual, the FHWA has identified a community as “adistinctive, homogenous, stable, self‐contained unit of a larger spatial area defined by geographic boundaries,ethnic, or cultural characteristics of the inhabitants; a psychological unity among the residents; and theconcentrated use of the area’s facilities. A community is an entity with economic, social and perhaps politicalfunctions. It usually has a name identity and number of community service facilities such as business districts,religious institutions, schools, health centers, and fire and police stations. By contrast, a neighborhood is asmall social unit based on face‐to‐face contacts.” The guidelines for determining neighborhood andcommunity boundaries contained in the Manual will be consulted for this criterion.

1Baseline is considered to be the conditions defined in the No‐Build Alternative. 2 Planning boundary is considered the outer limit of the 2035 land use plan for Bloomington and Normal.

• The region is divided into small geographic boundaries calledTAZ ‐ primary unit of analysis in a travel demand forecastingmodel.

• TAZs contain socioeconomic information such as number ofhouseholds, population, employment etc.

TAZ’ d i th d l t ti t t i b t• TAZ’s are used in the models to estimate trips betweengeographical areas.

• TAZ size varies based on population and employment density• TAZ size varies based on population and employment densityand spacing between roadways – TAZs in downtown areas aregenerally smaller than outlying areas.
