corrected, City staff met with the staff at the RWQCB to address their concerns and provide new information that demonstrated that no diversion of flow had taken place. While RWQCB staff acknowledged that the City provided the necessary documentation to disprove their theory about the divided water way, the RWQCB determined that a hydrology study of the area of Kottinger Creek within Lions Wayside Park would be necessary to adequately assess proposed changes to the channel. The consultant completed a preliminary hydrology study and presented the study and associated plans to the RWQCB in May 2021. The RWQCB indicated that more information would be required regarding the basis of design for the creek and that a more detailed hydrology analysis was necessary. In October 2021, the City entered into a contract with Balance Hydrologics to prepare preliminary creek design, hydraulic modeling, and a design basis memo for Kottinger Creek for a detailed discussion with the regulatory agencies at the ACE Interagency meeting. In January 2020, a first amendment to the agreement was issued for inclusion of the land acquisition at 4363 First Street and 4377 First Street. A second amendment was issued July 2020, extending the contract term only. DISCUSSION Staff recommends approval of Amendment No. 3 to the agreement with Moore, lacafano, and Goltsman, Inc. to present the preliminary hydrology study for the project at the ACE meeting and to update the master plan per regulatory agency comments. The additional costs $29,967 outlined in this report will be funded by CIP No. 06716, which currently holds approximately $2 million.
