Indicates an unsignalized intersection with side-street stop conoach LOS. The delay shown represents the worst side-street approach delay. Proposed Development The proposed development consists of a 17,750 square foot Goodwill retail store/donation center. Access to the proposed development is planned to be provided via the Arden Plaza East Access driveway along County Road E (see Figure 3: Site Plan). This access is shared with the adjacent apartment building to the west. Construction of the proposed development is expected to be completed in the year 2014. Year 2015 Build Conditions Traffic Forecasts Traffic forecasts were developed to provide an estimate for the future traffic volumes within the study area. As previously mentioned, construction of the proposed development is expected to be completed in the year 2014. Therefore, year 2015 build conditions (one year after construction) were reviewed. To account for general background growth in the area, an annual growth rate of one-half percent was applied to the existing peak hour volumes to develop year 2015 background traffic forecasts. This growth rate is consistent with historical average daily traffic (ADT) volumes. Furthermore since the adjacent apartment was recently opened, only 26 of the 74 units are currently occupied. Therefore the existing driveway turning movement counts were adj occupancy of the adjacent apartment. To identify traffic impacts associated with the proposed development, a trip generation estimate was completed for the proposed Goodwill store. These types of stores have been observed to generate trips differently than typical free standing discount stores. Therefore, historical observation data from two existing Goodwill locations (Maple Grove and Hopkins) was utilized. These surveys were completed by SRF Consulting Group in April 2010 during the p.m. peak period (i.e. between 4:30 p.m. and 6:00 p.m.). For comparison purposes, a trip generation estimate was also calculated using the ITE Trip Generation Manual, 9th Edition.
