10-9E-1: PURPOSE:
The LaFayette neighborhood is a unique area to the city, and is the subject of a component of the city comprehensive plan. The LaFayette neighborhood comprehensive plan component encourages growth in the area by means of the planned unit development approach. As multiple-family developments are proposed in the neighborhood and are found compatible by the city, the ordinance that is specific to the LaFayette neighborhood will be amended by adding the new development for the subject property. (Ord. 1098, 11-8-2004)
10-9E-2: TRAFFIC ALLOCATION:
A principal reason for planning the development of the LaFayette neighborhood by means of a specific comprehensive plan component and a separate ordinance unique to the neighborhood is that the traffic capacity of the main arterial streets in the neighborhood is limited. Consequently, to better assure that the key intersections in the neighborhood function at an acceptable level, and to allow for an equitable distribution of traffic to all properties in the neighborhood, regardless of whether they are the first or last to develop, traffic generation is carefully planned and monitored. Each proposed development is analyzed against the needs and resources of the whole neighborhood, and at the same time, the ordinance for the LaFayette neighborhood is amended by adding a new use/development. A peak P.M. rush hour traffic amount will also be allocated for the new use/development. (Ord. 1098, 11-8-2004)
10-9E-3: BULK STANDARDS:
The bulk standards for the LaFayette neighborhood are established in the ordinance specific to that neighborhood. (Ord. 1098, 11-8-2004)
10-9E-4: ALLOWABLE USES:
See table in section 10-6-1 of this title for a listing of allowable uses within the MF-PUD district. (Ord. 1098, 11-8-2004)
