217 • Frozen water pipes: how to solve the problem before the coming winter; and 218 Best Practices ideas from other communities or sources. 219 220 • Alternative salt/ice control materials and cost impacts. 221 222 At the request of Member Seigler, staff provided additional information on 223 why the City was moving away from using salt and toward other materials to 224 address stormwater runoff and negative impacts on water bodies, locally and 225 in the broader area. 226 AL 227 Mr. Culver suggested part of that discussion and research could be how to use 228 sodium chloride more effectively to provide safe driving situations for the 229 public, especially at intersections, but how to use less of the material, or 230 whether other chlorides would prove just as effective but have less of an 231 environmental impact. Mr. Culver noted that there were other mixes to be 232 researched that may have lower melting temperatures allo4King less material to 233 be used, along with beet juice and cheese brine as some of the materials being 234 studied and experimented with. Mr. Culver advised that staff would research 235 other items and report back to the PWETC to facilitate their discussion and 236 subsequent recommendation to the City Council. In response to discussion 237 among commissioners, staff noted that use of sand, while effective, also 238 provided its own pollution concer requiring its eventual removal from 239 bodies of water. It was the consensus of commissioners that public safety was 240 a vital part of this discussion, in addition to cost, water quality and pollution 241 issues; with staff noting that there also a limited amount of material available 242 and also that they were permitted to use. 243 244 Mr. Schwartz noted that some heating technology elements were currently 245 being used in Europe to some extent and had proven effective. 246 247 Pavement ondition ndex / Pavement Management Program (PMP) Goals. 248 Chair Stenlund stated that he had been personally shocked at the joint meeting 249 that any consideration was being given to reduce the current goals and 250 funding, opining that it would only make it more difficult and take more 251 money to get back to an acceptable level of service. Chair Stenlund suggested 252 a more prudent approach would be to hold the current level of service by 253 continuing a small investment now to avoid a major investment later. 254 However, Chair Stenlund stated that his take away from the meeting was a 255 charge by the City Council for the PWETC to research and make a 256 recommendation on the impact and potential cost savings if the Index goals 257 were dropped by 5%. 258 259 At the request of Member Seigler, Mr. Schwartz reviewed the City Council's 260 rationale in requesting that study based on the current reserves (e.g. interest 261 earnings) in the PMP reducing annual projects and future planning needs as 262 roads come up for reconstruction beyond normal maintenance.
