Planning Commission Meeting Minutes – Wednesday, March 02, 2011 Page 4 Mr. Lloyd advised that there were numerous components of the application still 148 outstanding, the City’s Public Works Department and City Engineer were finalizing 149 information on storm water and infrastructure with the applicant’s consulting engineer. Mr. 150 Lloyd advised that staff was recommending that, if approved by the Planning 151 Commission, approval be contingent upon provision of all outstanding detailed 152 engineering information prior to City Council action. 153 Mr. Lloyd reviewed the nature of an “Outlot” and intent to plat the proposed Outlot A 154 when future development scenarios were solidified enough to determine actual location 155 of lot lines. Mr. Lloyd advised that the existing pile of rubble, under stipulations of a recent 156 Interim Use approval, was located on the northern portion of the proposed Outlot. 157 Staff recommends approval of the PRELIMINARY PLAT, as detailed in Section 7 of the 158 staff report dated March 2, 2011; contingent upon provision of all outstanding detailed 159 engineering information prior to City Council action. 160 City Engineer Debra Bloom 161 At the request of Member Gottfried, City Engineer Debra Bloom reviewed the process of 162 public infrastructure improvements necessary to serve any given plat. Mr. Bloom noted 163 that the older unit was one lot, and was now being proposed for subdivision for up to 164 three (3) lots. Ms. Bloom reviewed the location of existing and future sanitary sewer 165 locations and extensions needing to be stipulated as part of the preliminary plat, as well 166 as identifying any additional rights-of-way and sidewalk extensions. Ms. Bloom advised 167 that the existing storm water infrastructure had been developed on the property prior to 168 development of current storm water regulations; and improvements would now need to 169 be incorporated into the parcel(s). Ms. Bloom noted that the Applicant’s consulting 170 engineer was aware of the required information, and expressed her confidence that the 171 information was forthcoming. Ms. Bloom further noted that Terminal Road had been 172 developed in the 1980’s as a private road at this location; and it was staff’s preference to 173 keep it private and not have it become a public roadway. Ms. Bloom advised that none of 174 the remaining engineering issues were insurmountable, but that it was staff’s charge to 175 ensure public improvement requirements were in place to meet future development 176 and/or redevelopment needs of the site. 177 Member Gottfried expressed concern in the Planning Commission holding the Public 178 Hearing prior to all technical aspects for the project being in place. 179 Ms. Bloom, as well as Mr. Lloyd, assured Commissioners that holding the Public Hearing 180 and reviewing the Preliminary Plat at this time, prior to completion of engineering 181 documents, were practical. 182 Applicant Representative, Clark Wicklund, Alliant Engineering 183 Mr. Wicklund addressed the issues addressed by Ms. Bloom: sanitary sewer, storm 184 sewer and sidewalk extension on Walnut; and addressed the status of each component. 185 Storm Sewer 186 Mr. Wicklund advised that site drainage was sufficient based on the previous 187 development on the site; and while there was no capacity issue, how to best treat the 188 runoff remained in process. Mr. Wicklund noted that there were a variety of options to 189 treat the drainage as the site developed, while addressing drainage from the City’s 190 perspective and the network of available surrounding storm sewers and concern that the 191 site may be tributary to a local regional retention pond. Mr. Wicklund advised that, in 192 working with staff, it was determined to route the northern portion of the site to an 193 already-installed storm sewer on County Road C2 and Walnut, thus bypassing the 194 regional pond, which had been of primary concern to City Engineer Bloom based on a 195 history of flooding at that lift station. 196 Mr. Wicklund noted that the site was already developed and surrounded by runoff 197 capacity, but that with the addition of newer stormwater management requirements, 198 discharge would be reduced from the site. However, Mr. Wicklund advised that until more 199 detail was known as individual users came forward, additional mitigation remained an 200
