RESOLUTION NO. 5339 A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF ARROYO GRANDE APPROVING CONDITIONAL USE PERMIT NO. 23-002 TO IMPLEMENT A STREAM GAUGE FISH PASSAGE IMPROVEMENT PROJECT ON PROPERTY LOCATED WITHIN ARROYO GRANDE CREEK IN PROXIMITY TO CLARENCE AVENUE AND MYRTLE STREET (APN 077-572-031), APPLIED FOR BY CREEK LANDS CONSERVATION (CLC), APPROVING THE REQUESTED FEE WAIVER, AND FINDING THE PROJECT EXEMPT FROM CEQA WHEREAS, the City Council of the City of Arroyo Grande has considered Conditional Use Permit No. 23-002, applied for by CLC to modify an existing broad- crested weir spanning the width of Arroyo Grande Creek ("Project"); and WHEREAS, the funding for the Project was received from the National Fish and Wildlife Foundation (NFWF) and the California Department of Fish and Wildlife (CDFW); and WHEREAS, CLC applied for and received funding through NFWF and CDFW to implement the proposed Project which will lower the weir and restore reliable access to 3.3 miles of critical steelhead habitat upstream of the barrier; and WHEREAS, the City Council has reviewed the project in compliance with CEQA and has determined that the project is exempt based upon Sections 15301, 15302, and 15304 of the State CEQA Guidelines for the reasons articulated below; and WHEREAS, the Project is consistent with General Plan Objective C/OS2, which aims to "[s]afeguard important environmental and sensitive biological resources contributing to healthy, functioning ecosystems." The Project is also consistent with General Plan Implementing Policy C/OS2-1.6: "[p];an, design, and develop sites to: Protect scenic resources, water quality and natural creekside habitat, including opportunities for wildlife habitation, rest, and movement. Further the restoration of damaged or degraded habitat, especially where a continuous riparian habitat corridor can be established;" and WHEREAS, on December 12, 2023, the City Council conducted a duly noticed public hearing to consider the staff report, recommendations by staff, and public testimony concerning the proposed ordinance. Following the public hearing, the City Council to adopt the prepared Resolution. NOW, THEREFORE, BE IT RESOLVED that the City Council of the City of Arroyo Grande finds, determines, resolves, and recommends: RESOLUTION NO. 5339 • PAGE 2 1. Recitals. All recitals above are true and correct and hereby incorporated by reference. 2. CEQA. This Project is exempt from review under the California Environmental Quality Act ("CEQA") pursuant to State CEQA Guidelines Section 15301 (Existing Facilities). This exemption consists of the operation, repair, maintenance or minor alterations to existing public or private structures involving negligible or no expansion of existing or former use. This includes maintenance of artificial wildlife waterway devices to protect fish and wildlife resources. Here, the Project involves the operation, repair, and minor alteration to the existing stream gauge that involves little to no expansion of the existing use. Further, the stream gauge will continue to be used for its original purpose of improving the critical steelhead trout habitat. Alternatively, the Project is also exempt from review under CEQA pursuant to State CEQA Guidelines Section 15302 (Replacement or Reconstruction). This exemption consists of the replacement or reconstruction of existing structures where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced. The Project will involve the reconstruction of the stream gauge, located on the same site as the existing stream gauge, and will have the same purpose of improving the steelhead trout habitat with the same capacity as the existing structure. Lastly, the Project is exempt from review under CEQA pursuant to State CEQA Guidelines Section 15304 (Minor Alterations to Land). This exemption consists of minor alterations in the condition of land, water, and/or vegetation which do not involve removal of healthy, mature, scenic trees. This includes minor alterations in land and water to fish production facilities which result in improvement of habitat for fish and wildlife resources or greater fish production. Here, the Project involves reconstruction of the stream gauge that will lead to the improvement of habitat for the steelhead trout. None of the exceptions to the categorical exemptions set forth in State CEQA Guidelines section 15300.2 have any applicability here. The Project will not impact any environmental resource of hazardous or critical concern, will not result in significant cumulative impacts, is not subject to any unusual circumstances that could result in a significant environmental impact, would not damage any scenic resources within a scenic highway, is not located on -2- RESOLUTION NO. 5339 PAGE 3 a hazardous waste site identified on any list compiled pursuant to Government Code section 65962.5, and would not impact an historical resource. Staff is directed to file the corresponding Notice of Exemption within five working days from the approval of this Project. 3. Conditional Use Permit Findings: a) The proposed use is permitted within the subject district pursuant to the provisions of this section and complies with all the applicable provisions of this title, the goals, and objectives of the Arroyo Grande General Plan, and the development policies and standards of the City. The proposed use of the site for a stream gauge improvement project is permitted with approval of a conditional use permit by the City Council after receiving a recommendation from the Planning Commission, and the project complies with all applicable provisions of the Arroyo Grande General Plan and Municipal Code. b) The proposed use would not impair the integrity and character of the district in which it is to be established or located. The proposed use of the site for a stream gauge improvement project will not impair the integrity of the project site due to the intent of the project to return the site to its natural condition after construction along with biological monitoring. c) The site is suitable for the type and intensity of use or development that is proposed. The site is an existing stream gauge that will be improved to remove a fish passage barrier. The type of development is suitable for the location near the creek and will be monitored by various responsible agencies. d) There are adequate provisions for water, sanitation, and public utilities and services to ensure public health and safety. The project involves completing a stream gauge replacement in Arroyo Grande Creek. No aspect of the proposed project is anticipated to be overly impactful to the existing services. Conditions of approval developed for the project will additionally ensure public services are minimally impacted. e) The proposed use will not be detrimental to the public health, safety or -3- RESOLUTION NO. 5339 PAGE 4 welfare or materially injurious to properties and improvements in the vicinity. The proposed use will not be detrimental to the public health, safety or welfare, nor materially injurious to properties or improvements in the vicinity, as it will comply with City conditions of approval specifically developed for the project as well as monitoring conditions required of the project's funding sources. 4. Fee Waiver. a) The proposed fee waiver request of$6,388 otherwise required for project is granted by the City Council because the project: i. Serves a public purpose of promoting the public health, safety, and general welfare by: 1) Implementing general plan policies to enhance natural creek functions and values by providing erosion control, sedimentation prevention, enhancement of riparian habitat corridors, water quality protection and aesthetic and recreational opportunities; and 2) Improving habitat for a federally threatened fish species. ii. Serves a public purpose by safeguarding important environmental and sensitive biological resources contributing to a healthy, functioning ecosystem. 5. Severability. If any section, division, sentence, clause, phrase or portion of this resolution or the document in the record in support of this resolution is determined by a court of competent jurisdiction to be invalid, unenforceable, unconstitutional or otherwise void, that determination shall not affect the validity of the remaining sections, divisions, sentences, clauses, phrases of this Resolution.
