Therefore, the reasonable worst-case scenario is 253,500 sf of building areal <br />• 40% of the site is parking, drive isles, and loading area <br />• 5% is landscape, stormwater facilities, and setbacks. EC 9.2450 shows that there are no <br />frontage setback requirements, minimal internal setbacks, and minimal landscaping are <br />also noted. The 5% is estimated using developed properties on 1-2 land along West 1st Ave <br />and South Bertelsen Road. While many lots had zero landscaping, it is assumed a new <br />building on 1-2 would have at least 5%. <br />The above building site was determined based on typical building, landscaping, and parking ratios <br />for this type of land use and what is required by code. The types of uses and sites were compared <br />until the maximum number of PM Peak Hour trips is achieved. The trip generation utilized rates <br />found within the ITE Trip Generation Manuals 10th Edition. <br />TABLE 1: WORST CASE-TRIP GENERATION EXISTING ZONING <br />II <br />ITE Land Use <br />140-Manufacturing <br />760-Research and Developm( <br />942- Automobile Care Center <br />920-Copy and Print Shop <br />816-Hardware/Paint <br />Total Trips <br />Size <br />(ksf) <br />Rate <br />Trips <br />146.5 <br />0.67 trips/ksf <br />98 <br />Center 50 <br />Ln(T) = 0.35Ln(X) + 2.36 <br />42 <br />37 <br />2.41(x)+11.8 <br />101 <br />10 <br />7.42 trips/ksf <br />74 <br />13 <br />2.68 trips/ksf <br />35 <br />328 <br />The ITE Land Uses are correlated to the uses allowed within Chapter 9, as detailed in Table 2. <br />TABLE 2: LAND USE CATEGORIES <br />EC Chapter 9 Land Use Description ITE Land Use Code <br />Manufacturing 140-Manufacturing <br />Scientific and Education Research Center 760- Research and Development <br />Car Repair, Paint and Body Shop 942- Automobile Care Center <br />Retail Trade Secondary to Products <br />920-Copy and Print Shop <br />Manufactured on Site <br />Retail and Trade Secondary to Products <br />Manufactured on Site 816-Hardware/paint <br />1 An example of a 3-story building on 1-2 zoning is the Thermo Fisher Scientific buildings located on Willow Creek <br />Rd.
