a April 6, 2021 Centerville Planning & Zoning Commission Page 5 of 9 RE: Rehbein Commercial - Preliminary Plat There are three potential scenarios, illustrated to the right: • Street A Not Extended - Access to Lot I/IA via cul-de-sac only • Street A Not Extended - Driveway access only at 20t" Avenue • Street A Extended If Lot 1 /1 A develops with only cul-de-sac access then all traffic serving the lots on Street A would come from 21 It Avenue, except traffic coming from Kwik Trip's right- in/right-out off Main Street (Lot 1/IA is not allowed its own R/R access onto Main Street). This scenario would push traffic onto 21 It Avenue and its signal at Main Street, but we don't know the level of those impacts. If Lot 1 /1 A develops with a driveway only at 20t", there still might be impacts to 21 It Avenue and the signals. If Street A is extended with full movement at 20t" Avenue, there might be a different set of conditions, with a bypass lane and turn lanes on 20t" Avenue. We suggest a traffic study is needed to quantify these impacts. The study would analyze the impacts to area roadways and traffic signals, comparing traffic conditions with full development of the Rehbein plat, in each of these three scenarios. If the impacts of not building Street A are significant, the City might require the street to be extended and the County's required improvements be made when development is approved for Lot 1 /1 A. If the impacts are negligible, the City could allow Lot 1 /1 A to develop with access only to the cul-de-sac or with R/R only. Regardless of If and when Street A is extended in the future, we suggest that street, sidewalk and trail ROW be dedicated now with this plat.
