Executive Summary
The purpose of this memo is to request Town Council authorization of a Resolution approving the Third Amendment to the Participation Agreement between the Cherry Creek Basin Water Quality Authority (CCBWQA) and the Town of Castle Rock (Town), for the Design and Construction of Stream Reclamation Improvement for McMurdo Gulch (see Attachment A). The Town has partnered with the CCBWQA on a number of projects since 2011 on McMurdo Gulch, with the CCBWQA contributing over $1,470,000 to date. In 2017, the Town completed a stream assessment of McMurdo Gulch that prioritized areas where McMurdo Gulch needed stream channel improvements. In 2020, the Town and the CCBWQA partnered to complete the Priority 1 improvements under separate agreement from the one being considered in this memo.
The Town entered into this Participation Agreement with the Authority in October 2020 for design of the Priority 2 stream reclamation improvements for McMurdo Gulch, followed by the First Amendment that authorized construction of the Priority 2 Improvements in December 2021. Second Amendment to the Participation Agreement approved June 2022 included a contribution for the design of the Priority 3 Improvements in the amount of $170,129. This Third Amendment to the Participation Agreement includes a contribution for construction of the Priority 3 Improvements in the amount of $1,290,347, which includes transfer of the remaining balance of funds from the Priority 1 and 2 Improvements in the amount of $251,380 and an additional contribution of $868,846 (see Exhibit 1 of Attachment A).
