Fiscal Impact Approval of the Canter Court Sewer Project (project) along with adoption of the Mitigated Negative Declaration (MND) and the Mitigation Monitoring and Environmental Commitment Program (MMP) allows the project to move toward the final design and construction phases. There is no fiscal impact as a direct result of adopting the MND, MMP, and approving the project. The project is estimated to cost approximately $290,475 and as budgeted, wi11 be funded through the Public Works Wastewater Utility fund. Alternative Action The City Council (Cauncil) may choose not ta adopt �he MND and the MMP, and not approve the project as described. Without approval, the project would not be able to proceed as a City of Redding (City) project, as it would not be in com�pliance with the California Environmental Quality Act (CEQA). Report to Redding City Council October 8,2024 Re: 4.12(a)--Canter Court Sewer Project Page 2 Background This project will replace two, 6-inch sewer siphons along Churn Creek in southeast Redding. Replacement of the siphons are needed to address the deteriorating and failing pipes. The project is located on City-owned property west of Canter Court and east of Cambria Drive. This project consists of the removal and replacement of the two existing 348-foot-long, 6-inch- diameter concrete-encased sewer siphons. The siphons would be excavated and replaced in the same alignment. An open-trench method requiring a work area approximately 20-feet wide and an excavation depth of approximately 12-feet is anticipated be used along the entire length of pipe to be replaced. The total length of the trench is estimated to be 348-feet in length, including an estimated 83-foot Churn Creek crossing. The two existing 6-inch-diameter acrylonitrile butadiene styrene siphon pipes will be removed and replaced with new 6-inch-diameter high- density polyethylene (HDPE) pipes. Work also includes the removal, replacement, and rehabilitation of three manholes. The existing 10- to 12-foot-wide maintenance access road accessed via Cambria Drive wi11 be improved by adding gravel to create an all-weather maintenance access. Additionally, a 120- foot-long by 25-foot-wide permanent easement wi11 be obtained to accoinmodate a portion of the improved maintenance road. An Initial Study (IS) was prepared to satisfy the requirements of CEQA. It describes why the Project is being proposed and the potential impacts to the existing environment. The IS shows that the proposed Project could have a significant effect on biological resources, but with implementation of mitigation measures, those impacts will be reduced to a level considered less than significant. The mitigation measures and conservation measures to be implemented are common practices and include but are not limited to biological pre-construction surveys, in- water work windows, impact minimization, exclusionary fencing, and erosion control. Based on the conclusions made in the IS, an MND was prepared. The MND describes the project, including mitigation measures, and makes the determination that there will be no significant effect on the environment provided that the defined mitigation measures are implemented as part of the project. In addition, an MMP has been written and incorporated into the 1VIND (CEQA Section 21081.6). The MMP wi11 be used by City staff, contractors, agencies, and monitoring personnel during and after the project to ensure effective implementation of the adopted mitigation measures outlined in the MN�D. The IS/MND/1VIMP documents were sent to the State Clearinghouse far a 30-day public review period and distribution to pertinent state agencies. They were sent to local resource agencies, the Shasta County Clerk, and posted on the Public Works Department website. A public notice was also sent to landowners in the vicinity of the project and posted in the local newspaper. No comment letters were received during the state agency or public review periods. Environmental Review Pursuant to CEQA, the City is the lead agency for the project. As the lead CEQA agency, the Council is authorized to adopt the MND per Redding Municipal Code Section §18.24.070.E and state law. Upon adoption of the MND and approval of the Project by the Council, a Notice of Determination will be filed with the Shasta County Clerk's Office and the State Clearinghouse, completing the environmental review process.

The purpose of the project is to replace two existin�sewer siphons that run under Churn Creek. Replaeement of these siphons is needed to address age-related deterioration. The project would consist of the removal and replacement of the two existing 348-faot-long, 6-inch- diameter conerete-encased sewer siphons aeross Churn Creek. The siphons would be exeavated and replaced in the same alignmcnt. An open-�rench method requiring a work area appraximately 20 feet wide and an excavation depth of approximately 12 feet wouid be used along the entire length af pipe to be replaced. The two existing 6-inch-diameter acrylonitrile butadiene styrene siphon pipes would be removed and replaeed with new 6-inch-diameter high-density polyethylene pipes in the sazne align�meilt. New pipe sections would be placed in the trench, fused tagether, and connected to manholes on both ends of the pipeline. When campleted,the trench would be baekf'illed with slurry and a canerete cap to prevent erasion during high winter flows. The d'zsturbed s�realn claannel bed and bank would be xeturned to its original contours and seeded with a locai native seed mix. Work aisa includes the removal of one manhole, the replacement of one manhole, and the rehabiiitation of a third�nanhole. The old siphon pipes, the reznoved xn�nhole�naterial, and the exeavated earthen znaterial would be taken ta a landfill, Construction is expeeted to require one canstruction season(Ju1y 1 through October 31)beginning in summer 2025. ENVIRONMENTAL SETTING The project area is located in a narrow band of open spaee and is cent�red on Churn Crael�, an intermittent stream. Natural riparian habitat is situated on either side of the stream. The open spaee is bounded by residential neighborhoads to the east and west. Each neighbarhoad includes a connection road to the open space and project area. FINDINGS AND QETERMINATION The City of Redding eonducted an Initial Study(attached)that determined that the propased prajeet could have signifieant environm�ntal effects on biaiogical resources. Implementation of specific mitigation measures identi�ed below will avoid or mitigate the potentially significant environmental effeets identified, and the preparation of an environmental impact report will not be required. Zf there are substantial changes that alter the character or impacts of the proposed project,another enviromnental impact detennination will be necessary. Canter Court Sewer Project Page 1 October 2024 City of Redding Public Worlcs Departmcnt,Enginecring Division Mitigated Negativc Declaration Prior to approval of the project,the lead agency may conclude, at a public hearing,that certain mitigation measures identified in the Mitiga�ed Negative Declaration are infeasible or undesirable, In accordance with California Environmental Quality Act(CEQA) Seetiol� 15074.1,the lead agency may delete those mitigation measures and substitute other measures that it determines are equivalent or more effeetive. The lead agency wotzld adopt written findings that the new measure(s}is{are) equivaient or more effective in mitigating or avaiding potential significant effects and that it would not cause any potentially signi�cant effect on the environment. 1} Based on the whole recard(ineluding th�Initial Study and any supparting documentation) and the mitigation measures incorporated into the project,the City of Redding has determii3ed that there is no substantial evidence tl�at the project will have a significant effect on the environznent. 2) Tha Mitigated Negativa Declaration,with its supparting documentation,reflects the independent judgment and analysis of the lead agency,which is the City of Redding. DOCUMENTATION The attached Initial Study docuinents the reasons to support the above determination. MITIGATION MEASURES The following miti�ation measures wili be incorporated into the project to minimize potential effects on biological resources: MM-1. All in-water work sha11 occur during July 1 ta Oetober 31 to avoid peak tiines when listed juvenile anadromous fish would be present. MM-2.Before dewatering,there wili be a visual inspectian for fish presence. If fish are noted,they will be herded away fram the work area,using seines if possible, and prevented from returning to the area using black nets. M -3.Environmental awareness training for eonstruction persannel will be eanducted by a qualified biologist prior to onset af work to brief them on how ta reeognize Northwestern pond turtle and the apprapriate avaidance measures. MM-4.Twenty-four hours prior to initiation of ground dist�urbance or vegetation removal, a quali�ed biologist shall perform a pre-eonstruction survey for western pond turtle and their nests. If western pond turtles are encountered in the project area dnring construction and could be harmed by eanstruction activities,work will stop immediately in the area and the individual turtles will be allowed to move away on their awn accord. If a Northwestern pand turtie nest is found, a qualified biologist(in consuitation with the CDFW and USFWS)w�ll determine the extent of a construetion-free buffer zone to be established around the nest. MM-5. If construction or vegetatian remova�oceurs during the nesting season, February 1 through August 31 for birds and November 1 through July 15 for raptars, a q�alified biologist shall conduet a preconstruction surv�y to locate aetive nests. Thc pre-construction survey wi11 b�performed no morc than 7 days prior ta the implementation of constuction activities.If a lapse in construction activities occurs for 7 days ar longer, anather pre-construetion survey will be performed. If an active nest is found, a qualified Page 2 Canter Court Sewer Project October 2024 City af Rcdding Mitigated Negative Dec]aration Public Works Department,Engineering Division biologist{in cansultation with the CDFW)will determine the extent of a buffer zone to be established. around the nest. MM-6.To the extent practicable,removal of large trees with caviti�s, crevices, or snags shall occur before bat maternity colonies form(i.e.,prior to March 1}or after young are volant(i.e., after August 31}. If construction(including the removal af large trees}oceurs during th�bat non-volant season(Mareh 1 through August 31), a qualified professional shall conduct a pre-construction survey of the study area to locate matenuty colonies anc�identify measures to protect colonies from disturbance. The preconstruction survey will be performed no inore than 7 days prior to the implementation of construction activities. If a maternity colony is located within or adjacent to the study area,a dist�urbance free buffer sha11 be established by a qualified prafessional,in consultation with CDFW,to ensure the colony is protected from project activities. MM-'1.To the extent practieable,remaval of riparian brush will occur outside of the maternal d�nning period(i.e., July 1—April 30), If vegetation reinoval is to occur during the inaternal denning period(May 1—June 30),a qualified biologist will conduct a preconstructian survey of the study area to locate maternity dens and identify ineas�res to protect the maternity dens fram disturbance. The preconstruction survey will be performed no more than seven days prior to the vegetation removal. MM-8.High visibility feneing, flagging,or markers wi11 be installed along the edges of the worlc zane near culturally sensitive zone to prevent damage or unauthorized access.

The 1V1MP/ECP includes a brief discussion of the legal basis for, and the purpose of,the program, discussion, and direction regarding complaints about noncompliance; a key to understanding the monitoring matrix; and the monitoring matrix. LEGAL BASIS OF AND PURPOSE FOR THE MITIGATION MONITORING PROGRAM California Public Resources Code Section 21081.6 requires public agencies to adopt mitigation monitoring or reporting programs whenever certifying an environmental impact report(EIR) or a mitigated negative declaration(MND). This requirement facilitates unplementation of all mitigation measures adopted through the California Environmental Quality Act(CEQA)process. The MMP contained herein is intended to satisfy the requirements of CEQA as they relate to the Initial Study/Mitigated Negative Declaration prepared for the project. It�s intended to be used by City of Redding(City) staff,participating agencies,project contractors, and mitigation monitoring personnel during implementation of the project. Mitigation is defined by CEQA Guidelines Section 15370 as a measure that does any of the following: ■ Avoids impacts altogether by not taking a certain action or parts of an action. ■ Minimizes impacts by limiting the degree or magnitude of the action and its implementation. ■ Rectifies impacts by repairing,rehabilitating, or restoring the impacted environment. ■ Reduces or eliminates impacts over time by preservation and maintenance operations during the life of the project. ■ Compensates for impacts by replacing or providing substitute resources or environments. The intent of the MMP is to ensure the effective implementation and enforcement of adopted mitigation measures and permit conditions. The MMP will provide for monitoring of construction activities as necessary, onsite identification and resolution of enviromnental problems, and proper reporting to City staff. In addition to meeting the CEQA MMP requirelnents,this document incorporates environmental commitments, standard practices,conservation measures, and best management practices(BMPs). The environmental commitments may be part of the project design, standard contract speci�cations, City requirements, or conservation measures. These coininitments are part of the project,but they do not constitute mitigation under CEQA as they have not been incorporated to reduce a potentially significant impact. Canter Court Sewer Project Page 1 October 2024 City of Redding Public Works Departmcnt,Engineerin�Division Mitigation Monitoring Program MITIGATION MONITORING/ENVIRONMENTAL COMMITMENT PROGRAM TABLE The MMP/ECP Table identifies the mitigation measures and commitments proposed for the project. The tables have the following columns: ■ Mitigation Measure: Lists the mitigation measures identified within the Initial Study for a specific potentially significant impact, along with the number for each measure as enumerated in the Initial Study. ■ Environmental Commitment: Lists the commitments identified within the project that are not related to a potentially significant CEQA impact,but further ensure environmental resource protection. ■ Timing: Identifies at what point in time,review process, or phase the mitigation measure will be completed. ■ Agency/Department Consultation: References the City department or any other public agency with which coordination is required to satisfy the identified mitigation measure. ■ Verification: Spaces to be initialed and dated by the individual designated to verify adherence to a specific mitigation measure. NONCOMPLIANCE COMPLAINTS Any person or agency may file a complaint asserting noncompliance with the mitigation measures and commitments associated with the project. The complaint shall be directed to the City in written form, providing specific information on the asserted violation. The City sha11 investigate and determine the validity of the complaint. If noncoinpliance with a mitigation measure has occurred,the City shall take appropriate action to remedy any violation.The compliant shall receive written confirmation indicating the results of the investigation or the final action corresponding to the particular noncomplianee issue.
