Findings. The City Council finds and declares that: (a) Article VIII of the Charter of the City of Palo Alto and Section 22.08.005 of the Palo Alto Municipal Code (PAMC) require that, before any substantial building, construction, reconstruction or development is commenced or approved, upon or with respect to a ny land held by the City for park purposes, the Council shall first cause to be prepared and by ordinance approve and adopt a plan therefor. (b) The Palo Alto Flood Basin Tide Gate Structure (Structure) is part of the Adobe Creek Loop Trail (Trail). The Structure is located in the City’s Baylands, which is dedicated parkland (See PAMC § 22.08.020 et seq.) Based on the Conditional Structural Assessment of the existing Structure and reduced functionality, the Structure is planned to be replaced. (c) The City of Palo Alto intends to authorize Santa Clara Valley Water District (Valley Water) to construct a replacement Structure. The new Structure will replace the existing 1957- built Structure which has outlived its intended service life and has been re commended for replacement. (d) The Plan of improvements shall comprise, as follows: (1) The Project will construct a replacement Structure near the existing Structure, and new levees to connect the Trail to the replacement Structure. The project will re-align a portion of the levees and Trail as required to accommodate the replacement Structure location. The existing Structure will be removed after the replacement Structure and levees are constructed. Select plan sheets showing the in-progress design are attached as Exhibit “A”. (2) The Project will require temporary closures to portions of the Trail to accommodate construction of the replacement Structure and connecting levee work. A diagram illustrating anticipated Trail closures is attached as Exhibit “B”. If the replacement Structure is not constructed, future degradation of the existing Structure will occur and would eventually require closure of the Trail for an unknown duration of time.

This new motor operated sluice gate will replace the existing motor operated sluice gate which is owned and operated by the City. The Structure will also include new water level sensors and Supervisory Control and Data Acquisition (SCADA) system to improve flexibility and efficiency for the City’s sluice gate operations. The new sluice gate will enable remote operation of the sluice gate. The replacement Structure with its improved operations and maintenance features and improved hydraulic performance is anticipated to reduce mosquito breeding within the PAFB compared to the existing conditions. (e) The Project described above and as otherwise depicted in the attached exhibit s is consistent with recreation and conservation purposes (f) The Council desires to approve the Plans for the Project described above and as depicted in Exhibit "A" and Exhibit “B”. SECTION 2. The Council hereby approves the Plan for construction of the Palo Alto Flood Basin Tide Gate Structure Replacement Project as described in this Ordinance. SECTION 3. Valley Water is the Lead Agency for the Project under the California Environmental Quality Act (CEQA). Valley Water performed an Initial Study and determined that a Mitigated Negative Declaration (MND) is the appropriate level of review. A resolution adopting the Final MND (Resolution) was signed by Valley Water’s Board on April 27, 2021. The Final MND and Resolution are available online from the project website: https://www.valleywater.org/pafbtidegates. The City Council finds that the City of Palo Alto is a responsible agency under CEQA for the Project and certifies that it has reviewed and considered the information contained in Valley Water’s MND. Valley Water has applied for regulatory permits from six resource agencies and are currently working with the resource agencies for mitigation requirements and permit conditions. // // // // // DocuSign Envelope ID: 0212DB79-F5E8-42B8-AB33-979184EDAB41 3 245_20220127_ts24 SECTION 4.
