Authorizing Barr Engineering Company to Perform Phase 1 Sediment Sampling in Silver View Pond <br />Page 2 <br />help control the overall costs for the sampling work. If initial sampling results indicate that the level <br />of contaminants varies throughout the pond, it may be beneficial to take additional samples to <br />determine the boundaries of the contamination and manage material separately based on the <br />different contamination levels. Although there will be additional costs to sample, there would likely <br />be lower costs for material removal and disposal. The need for a second phase would be <br />determined after reviewing the initial sampling results. <br />Phase 1 sampling includes thirteen samples. A map showing the proposed sampling locations is <br />attached for reference. Public Works originally solicited a fee proposal for Phase 1 sampling from <br />Barr in June 2013 for $12,300 ($950/sample) at which time the City Council instructed staff to <br />budget into the 2014 Budget. The 2014 Budget includes $12,500 under the stormwater enterprise <br />fund (245-4415-3030) for this work. Unfortunately, analytical analysis and testing costs have <br />increased since last June and Barr's current fee estimate is now $15,600 ($1,200/sample). The <br />same account in the stormwater enterprise fund also includes $7,500 for consulting engineers that <br />can account for the shortfall. <br />Recommendation: <br />Public Works recommends that the City Council adopt the attached resolution authorizing Barr <br />Engineering Company to perform initial (phase 1) sediment sampling and assessment for Silver <br />View Pond. In addition to providing a more accurate estimate for budgetary purposes, completing <br />the assessment will allow the City to apply for future grants available to assist municipalities in <br />removing and disposing of pond sediments. <br />Respelctfullyl submitted, <br />Nick DeBar— Director of Public Works <br />
