The City of Manteca adopted the Initial Study/Mitigated Negative Declaration and approved the Central Trunk Sewer Project on June 16, 2026.

Project Location
The City of Manteca Central Trunk Sewer Project (Project) area consists of approximately 0.8 mile in length and 40 feet wide for the proposed new segment of sewer line within the City. The Project Site is located within Section 31, Township 1 South, Range 7 East, Mount Diablo Base and Meridian, as depicted on the 1994 minor revised edition of the 1980 photorevised edition of the 1952 U.S. Geological Survey Manteca, California 7.5-minute quadrangle.

Summary Project Description
The Central Trunk Sewer Replacement Project (Project) consists of the replacement of an existing 36-inch diameter sanitary sewer trunk line that is deteriorated and aged connecting to the Union Road Lift Station (URLS) located within the Parks Department Corporation Yard. The new 36-inch trunk sewer line will be approximately 4,300 LF of 36-inch PVC SDR 26 pipe. The existing lifting station will be decommissioned in the future by others. The new sewer line will begin downstream near the newly constructed subdivision off the Airport Road and extend eastward through the Kaiser Development, crossing the canal, through the Manteca Park Golf Course, continuing under the Parks Department Corp Yard and tie-in to the URLS at an existing sewer manhole.

The City of Manteca, as the Lead Agency, has approved the above-described Project and has made the following determinations:

CITY OF MANTECA CENTRAL TRUNK SEWER PROJECT
Summary
Lead Agency: City of Manteca Central Trunk Sewer Project Project Location: The City of Manteca Central Trunk Sewer Project (Project) area consists of approximately 0.8 mile in length and 40 feet wide for the proposed new segment of sewer line within the City. The Project Site is located within Section 31, Township 1 South, Range 7 East, Mount Diablo Base and Meridian, as depicted on the 1994 minor revised edition of the 1980 photorevised edition of the 1952 U.S.

Geological Survey Manteca, California 7.5-minute quadrangle.

Summary Project Description: The Central Trunk Sewer Replacement Project (Project) consists of the replacement of an existing 36-inch diameter sanitary sewer trunk line that is deteriorated and aged connecting to the Union Road Lift Station (URLS) located within the Parks Department Corporation Yard.

The new 36-inch trunk sewer line will be approximately 4,300 LF of 36-inch PVC SDR 26 pipe. The existing lifting station will be decommissioned in the future by others. The new sewer line will begin downstream near the newly constructed subdivision off the Airport Road and extend eastward through the Kaiser Development, crossing the canal, through the Manteca Park Golf Course, continuing under the Parks Department Corp Yard and tie-in to the URLS at an existing sewer manhole.

Finding: Based on the information contained in the attached Initial Study, the City of Manteca finds that there would not be a significant effect on the environment because the mitigation measures described herein would be incorporated as part of the Proposed Project.

Mitigation Measures Incorporated into the Project to Avoid Significant Effects Biological Resources
BIO-1: Special-Status Plant Habitat Avoidance. The following measures shall be implemented to avoid impacts to Special-Status Plant Habitat within the pipeline alignment:
 A special-status plant survey shall be conducted according to California Department of Fish and Wildlife (CDFW), California Native Plant Society, and U.S. Fish and Wildlife Service (USFWS) protocols prior to Project ground-disturbing or vegetation disturbing activities within undeveloped areas. The survey shall be conducted by a qualified biologist (as defined per agency protocols) throughout all potential habitat for specialstatus plants within the Project Site and a 15-foot buffer. The survey shall be timed according to the identifiable period for special-status plant species with potential to occur (typically the blooming period). To the extent feasible, known reference populations shall be visited prior to the survey to confirm target species are evident and identifiable at the time of the survey. If no special-status plants are found and the survey is still considered recent as per CDFW and USFWS protocols at the time of Project implementation, no further measures pertaining to special-status plants are necessary. If City of Manteca Central Trunk Sewer Project
Final Mitigated Negative Declaration Approval
Final Mitigated Negative Declaration ii June 2026
a special-status plant is identified within or adjacent to the Project Site, the following shall apply.
 An impact assessment shall be made by a qualified biologist to determine whether Project-related activities would be significant such that they would have the potential to eliminate, substantially reduce the number of, or restrict the range of the special-status plant species, and/or conflict with any local policies or ordinances protecting specialstatus plant species. If impacts are determined to be less than significant, no further measures are needed.
 If potential impacts are determined to be significant, then a no-disturbance buffer shall be established around special-status plant populations to be avoided within or adjacent to the Project Site. The no-disturbance buffer shall include the extent of the avoided special-status plants (as determined by a qualified biologist during an appropriate time to identify the plants immediately preceding construction) plus a minimum 15-foot buffer. The avoidance area shall be clearly demarcated in the field and demarcation shall be maintained for the duration of Project construction. No vegetation-disturbing or ground-disturbing activities shall occur within the avoidance area.

BIO-2: Northwestern Pond Turtle. A qualified biologist shall conduct a preconstruction clearance survey within the Project Site within 48 hours prior to the initiation of Project construction activities. If there is a lapse in Project-related work of 14 days or longer, the survey must be repeated prior to resuming Project activities. If northwestern pond turtles are found within or near the Project Site during the survey or during Project implementation, they shall be allowed to move out of the Project Site on their own volition or relocated by a qualified biologist in coordination with CDFW and silt fencing shall be installed.

BIO-3: Nesting Bird. If construction is scheduled during the nesting season (typically February 1– August 31, and as early as January 1 for raptors), a qualified biologist shall conduct a preconstruction nesting bird survey within 14 days prior to the commencement of Project related activities to identify active nests that could be impacted by construction. The survey shall be conducted within the Project Site and a 500-foot buffer for raptors and a 100-foot buffer for other birds, where accessible. If there is a lapse in Project-related work of 14 days or longer, the survey must be repeated prior to resuming Project activities. If active nests are found, a no-disturbance buffer shall be established around the nest. A qualified biologist shall establish a buffer distance. The buffer shall be maintained until the nestlings have fledged (e.g., are capable of flight and become independent of the nest), to be determined by a qualified biologist. The avoidance buffer can be removed, and no further measures are necessary once the young have fledged or the nest is no longer occupied, as determined by a qualified biologist.

BIO-4: Burrowing Owl. A qualified biologist shall conduct a take avoidance preconstruction survey according to the Staff Report on Burrowing Owl Mitigation. If active/occupied burrows are City of Manteca Central Trunk Sewer Project
Final Mitigated Negative Declaration Approval
Final Mitigated Negative Declaration iii June 2026
detected, a no-disturbance buffer shall be established around the burrow. The buffer distance shall be established in coordination with CDFW.

BIO-5: Swainson’s Hawk. If construction is scheduled during the Swainson’s hawk nesting season (March 1 to August 31), then, a qualified biologist shall conduct a survey for Swainson’s hawk nesting activity within a 0.5-mile distance surrounding the Project Site. The qualified biologist shall conduct surveys according to the Recommended Timing and Methodology for Swainson’s Hawk Nesting Surveys in California’s Central Valley or, if proposing an alternate survey methodology, shall submit the proposed survey timing and methods to CDFW for review and written approval prior to the initiation of surveys. If there is a lapse in Project related work of 14 days or longer, the survey must be repeated prior to resuming Project activities. If Swainson’s hawk nesting activity is observed during the survey, an avoidance buffer shall be established by a qualified biologist in consultation with CDFW. The avoidance buffer shall be maintained while the nest is active.

BIO-6: Western Red Bat. Tree trimming/removal shall occur outside of the bat maternity season (April 15 through August 31), as feasible.

BIO-7: Aquatic Resources. Construction in this area will take place in one phase and will be completed before the irrigation ditch is used to convey any water.

Additionally, the applicant shall prepare and implement an Erosion and Sediment Control Plan to avoid and minimize sediment and erosion to aquatic resources within or adjacent to the Project Site boundary.

BIO-8: Tree and Vegetation Removal. The Project proponent shall consult with the City of Manteca Parks and Recreation Department prior to impacting vegetation in any public space and shall secure their approval for impacting such vegetation prior to construction, if needed.

Cultural Resources
CUL-1: Unanticipated Discoveries. If subsurface deposits believed to be cultural or human in origin are discovered during construction, all work must halt within a 100-foot radius of the discovery. A qualified professional archaeologist, meeting the Secretary of the Interior’s Professional Qualification Standards for prehistoric and historic archaeology, shall be retained to evaluate the significance of the find, and shall have the authority to modify the no-work radius as appropriate, using professional judgment. The following notifications shall apply, depending on the nature of the find:
 If the professional archaeologist determines that the find does not represent a cultural resource, work may resume immediately and no agency notifications are required.
 If the professional archaeologist determines that the find does represent a cultural resource from any time period or cultural affiliation, the archaeologist shall immediately notify the lead agencies. The agencies shall consult on a finding of City of Manteca Central Trunk Sewer Project
Final Mitigated Negative Declaration Approval
Final Mitigated Negative Declaration iv June 2026
eligibility and implement appropriate treatment measures, if the find is determined to be a Historical Resource under the California Environmental Quality Act (CEQA), as defined by CEQA or a Historic Property under Section 106 of the National Historic Preservation Act, if applicable. Work may not resume within the no-work radius until the lead agencies, through consultation as appropriate, determine that the site either: 1) is not a Historical Resource under CEQA or a Historic Property under Section 106; or 2) that the treatment measures have been completed to their satisfaction.
 If the find includes human remains, or remains that are potentially human, they shall ensure reasonable protection measures are taken to protect the discovery from disturbance (Assembly Bill [AB] 2641). The archaeologist shall notify the San Joaquin County Coroner (per § 7050.5 of the Health and Safety Code). The provisions of § 7050.5 of the California Health and Safety Code, § 5097.98 of the California Public Resources Code (PRC), and AB 2641 will be implemented. If the coroner determines the remains are Native American and not the result of a crime scene, the coroner will notify the Native American Heritage Commission (NAHC), which then will designate a Native American Most Likely Descendant (MLD) for the Project (§ 5097.98 of the PRC). The designated MLD will have 48 hours from the time access to the property is granted to make recommendations concerning treatment of the remains. If the landowner does not agree with the recommendations of the MLD, NAHC can mediate (§ 5097.94 of the PRC). If no agreement is reached, the landowner must rebury the remains where they will not be further disturbed (§ 5097.98 of the PRC).

This will also include either recording the site with NAHC or the appropriate Information Center; using an open space or conservation zoning designation or easement; or recording a reinternment document with the county in which the property is located (AB 2641). Work may not resume within the no-work radius until the lead agencies, through consultation as appropriate, determine that the treatment measures have been completed to their satisfaction.

Paleontological Resources
GEO-1: Discovery of Unknown Resources. If any paleontological resources (i.e., fossils) are found during Project construction, construction shall be halted immediately in the subject area, and the area shall be isolated using orange or yellow fencing until the City is notified and the area is cleared for future work. A qualified paleontologist shall be retained to evaluate the find and recommend appropriate treatment of the inadvertently discovered paleontological resources. If the City resumes work in a location where paleontological remains have been discovered and cleared, the City will have a paleontologist onsite to confirm that no additional paleontological resources are in the area.

Transportation
City of Manteca Central Trunk Sewer Project
Final Mitigated Negative Declaration Approval
Final Mitigated Negative Declaration v June 2026
TRANS-1: Construction Traffic Management Plan. Prior to commencing construction of the Proposed Project, a construction traffic management plan shall be prepared by the Contractor, in coordination with the City. The management plan shall be detailed and comprehensive to adequately mitigate potential conflicts between baseline and construction-related traffic. The construction traffic management plan will include, at a minimum, the following measures:

A. Adequate off-street worker parking shall be provided along the pipeline route.

B. A flagman or signal-controlled one-way traffic-control operation shall be provided where two-way traffic operation is impractical or unsafe.

C. Roadway disturbances shall be minimized during non-working hours; open trenches shall be covered with steel plates or by the use of temporary backfill during nonworking hours.

D. Temporary steel plate trench crossings shall be provided as needed to maintain access to homes, farms, and businesses.

E. Construction sites shall be posted with appropriate warning signage at least one week prior to construction to allow local residents to select an alternative travel route.

F. Construction staging areas shall be provided to minimize storage of equipment and materials in the traffic lanes.

G. All paved surfaces disturbed during construction shall be repaved when work is complete.

H. The Contractor shall provide traffic control and diversion plans for review and approval by each appropriate jurisdiction.

I. To minimize delays in emergency response during Project construction, emergency providers shall be notified in advance. Police, fire protection, and ambulance services shall be notified in advance of the times, duration, and location of construction activities throughout the Project’s construction process.

Tribal Cultural Resources
TCR-1: Unanticipated Discovery of Tribal Cultural Resources. If potentially significant TCRs are discovered during ground disturbing activities, all work shall cease within 100 feet of the find. A Native American Representative from the Confederated Village of Lisjan Nation shall be immediately contacted and invited to assess the significance of the find and make recommendations for further evaluation and treatment, as necessary. If deemed necessary by the City, a qualified cultural resources specialist, who meets the Secretary of Interior’s Standards and Qualifications for Archaeology, may also assess the significance of the find in joint consultation with Native American representatives to ensure that tribal values are City of Manteca Central Trunk Sewer Project
Final Mitigated Negative Declaration Approval
Final Mitigated Negative Declaration vi June 2026
considered. Work at the discovery location cannot resume until the City, in consultation as appropriate and in good faith, determines that the discovery is either not a TCR, or has been subjected to culturally appropriate treatment, if avoidance and preservation cannot be accommodated.

1.0 INTRODUCTION
This document is the Final Initial Study and Mitigated Negative Declaration (Final IS/MND) including the Responses to Comments and the Mitigation Monitoring and Reporting Plan for the City of Manteca Central Trunk Sewer Project. It has been prepared in accordance with the California Environmental Quality Act (CEQA) (Public Resource Code Section 21000 et. seq.) and the State CEQA Guidelines (California Code of Regulations Section 15000 et seq.) as amended. This Final IS/MND and Responses to Comments document supplements and updates the Draft Initial Study/Mitigated Negative Declaration (Draft IS/MND) released for public review on April 24, 2026.

The City of Manteca (City) is the Lead Agency for the Proposed Project. On April 24, 2026, the City distributed the Draft IS/MND for the Project to public agencies and the general public for review and comment. In accordance with the State CEQA Guidelines, a 30-day review period, which ended on May 25, 2026, was completed. During the public review period no comments were received.

This Final IS/MND is organized as follows:

Section 1.0 provides a discussion of the purpose of the document and discusses the structure of the document;
Section 2.0 contains a summary of the Project Description, and a discussion of why recirculation of the Draft IS/MND is not required;
Section 3.0 includes the comment letter received and responses to these comments; Section 4.0 includes corrections and revisions made to the Draft IS/MND in response to comments; Section 5.0 includes the Proposed Project’s Mitigation Monitoring and Reporting Program (MMRP), prepared pursuant to Public Resources Code Section 21081.6; and Section 6.0 includes the Notice of Intent, Proof of Publication, Environmental Filing Receipt, and the Draft IS/MND.

This Final MND document and the Draft IS/MND together constitute the environmental document for the proposed Project. As a result of comments received on the Draft IS/MND, minor revisions were required to the Draft IS/MND text, however, there were no substantial revisions that would require recirculation of the document. A substantial revision according to Section 15073.5 of the 2021 CEQA Statute Guidelines shall mean:
“(1) A new, avoidable significant effect is identified and mitigation measures or project revisions must be added in order to reduce the effect to insignificance, or (2) The lead agency determines that the proposed mitigation measures or project revisions will not reduce potential effects to less than significance and new measures or revisions must be required.”

2.0 PROJECT OVERVIEW

2.1 Project Location
The City of Manteca Central Trunk Sewer Project (Project) consists of approximately 0.8 mile in length and 40 feet wide for the proposed new segment of sewer line within the City. The Project Site is located within Section 31, Township 1 South, Range 7 East, Mount Diablo Base and Meridian, as depicted on the 1994 minor revised edition of the 1980 photorevised edition of the 1952 U.S. Geological Survey Manteca, California 7.5-minute quadrangle.

2.2 Project Description Summary
The Central Trunk Sewer Replacement Project (Project) consists of the replacement of an existing 36-inch diameter sanitary sewer trunk line that is deteriorated and aged connecting to the Union Road Lift Station (URLS) located within the Parks Department Corporation Yard. The new 36-inch trunk sewer line will be approximately 4,300 LF of 36-inch PVC SDR 26 pipe. The existing lifting station will be decommissioned in the future by others. The new sewer line will begin downstream near the newly constructed subdivision off the Airport Road and extend eastward through the Kaiser Development, crossing the canal, through the Manteca Park Golf Course, continuing under the Parks Department Corp Yard and tie-in to the URLS at an existing sewer manhole.

2.3 Decision Not to Recirculate Draft MND
According to Section 15073.5 of the State CEQA Guidelines, “A lead agency is required to recirculate a negative declaration when the document must be substantially revised after public notice of its availability has been given pursuant to Section 15072 but prior to its adoption.” Because no revisions were proposed, this Final MND does not meet the criteria for recirculation provided in Section 15073.5 (c) of the CEQA Guidelines. These criteria are provided below, along with an explanation regarding the reasons why the changes to the Project do not require recirculation.

Recirculation is not required under the following circumstances:
(1) Mitigation measures are replaced with equal or more effective measures pursuant to Section 15074.1.
a. Based on the conclusion of tribal consultation, minor revisions were made to TCR-1.

The addition of new language was not to provide any additional coverages, minimizations, or decrease findings. The new language was strictly to reflect the request of the tribe while maintaining the original content of the mitigation measure. Therefore, the intent of the original mitigation has not changed and recirculation is not required.
(2) New Project revisions are added in response to written or verbal comments on the Project’s effects identified in the proposed negative declaration which are not new avoidable significant effects.

City of Manteca Central Trunk Sewer Project
Final Mitigated Negative Declaration Approval
Project Overview 2-2 June 2026
a. No revisions to the Project as described in the Draft IS/MND have been made. (3) Measures or conditions of Project approval are added after circulation of the negative declaration, which is not required by CEQA, which do not create new significant environmental effects, and are not necessary to mitigate an avoidable significant effect. a. As discussed, no new mitigation measures were added. Once mitigation measure we slightly revised however, the project findings with incorporation of the new language has not changed and is still less than significant. (4) New information is added to the negative declaration which merely clarifies, amplifies, or makes insignificant modifications to the negative declaration. a. No new information has been added to the MND.

DECLARATION
During the 30-day public review period, April 24, 2026, through May 25, 2026, no public or agency comments were received. However, results of consultation with the Lisjan Nation have resulted in minor changes to the TCR-1 Mitigation. New text is shown with an underline and old removed text is shown with a strikethrough.

Tribal Cultural Resources
TCR-1: Unanticipated Discovery of Tribal Cultural Resources. If potentially significant TCRs are discovered during ground disturbing activities, all work shall cease within 50 100 feet of the find. A Native American Representative from the Confederated Village of Lisjan Nation traditionally and culturally affiliated Native American Tribes that requested consultation on the Project shall be immediately contacted and invited to assess the significance of the find and make recommendations for further evaluation and treatment, as necessary. If deemed necessary by the City, a qualified cultural resources specialist, who meets the Secretary of Interior’s Standards and Qualifications for Archaeology, may also assess the significance of the find in joint consultation with Native American representatives to ensure that tribal values are considered. Work at the discovery location cannot resume until the City, in consultation as appropriate and in good faith, determines that the discovery is either not a TCR, or has been subjected to culturally appropriate treatment, if avoidance and preservation cannot be accommodated.

Mitigation Monitoring and Reporting Plan 5-1 June 2026

5.0 MITIGATION MONITORING AND REPORTING PLAN

5.1 Introduction
In accordance with CEQA, an MND that identifies adverse impacts related to construction and operation of the Project was prepared. The MND identifies mitigation measures that would reduce or eliminate these impacts.

Section 21081.6 of the Public Resources Code and Sections 15091(d) and 15097 of the State CEQA Guidelines require public agencies to adopt a reporting and monitoring program for changes to the project which it has adopted or made a condition of project approval in order to mitigate or avoid significant effects on the environment. An MMRP is required for the proposed Project because the IS/MND identified potentially significant adverse impacts related to construction and operation of the proposed Project, and mitigation measures have been identified to mitigate these impacts. Adoption of the MMRP will occur along with approval of the proposed Project.

5.2 Purpose of the Mitigation Monitoring and Reporting Plan This MMRP has been prepared to ensure that all required mitigation measures are implemented and completed according to schedule and maintained in a satisfactory manner during the construction and operation of the Proposed Project, as required. The MMRP may be modified by the City of Manteca during Project implementation, as necessary, in response to changing conditions or other Project refinements. Table 5-1 has been prepared to assist the responsible parties in implementing the MMRP.

This table identifies the category of significant environmental impact(s), individual mitigation measures, monitoring and mitigation timing, responsible person/agency for implementing the measure, monitoring, and reporting procedure, and notation space to confirm implementation of the mitigation measures. The numbering of the mitigation measures follows the numbering sequence in the IS/MND.

5.3 Roles and Responsibilities
The City of Manteca is responsible for oversight of compliance of the mitigation measures in the MMRP.

5.4 Mitigation Monitoring and Reporting Plan
The column categories identified in Table 5-1 are described below.

Mitigation Measure – This column lists the mitigation measures by number.

Monitoring Activity/Timing/Frequency/Schedule – This column lists the activity to be monitored for each mitigation measure, the timing of each activity, and the frequency/schedule of monitoring for each activity.

The provisions of § 7050.5 of the California Health and Safety Code, § 5097.98 of the California Public Resources Code (PRC), and AB 2641 will be implemented. If the
coroner determines the remains are Native American and
not the result of a crime scene, the coroner will notify the Native American Heritage Commission (NAHC), which
then will designate a Native American Most Likely
Descendant (MLD) for the Project (§ 5097.98 of the PRC).

The designated MLD will have 48 hours from the time
access to the property is granted to make
recommendations concerning treatment of the remains.

If the landowner does not agree with the
recommendations of the MLD, NAHC can mediate
(§ 5097.94 of the PRC). If no agreement is reached, the landowner must rebury the remains where they will not
be further disturbed (§ 5097.98 of the PRC). This will also include either recording the site with NAHC or the
appropriate Information Center; using an open space or
conservation zoning designation or easement; or
recording a reinternment document with the county in
which the property is located (AB 2641). Work may not
resume within the no-work radius until the lead agencies, through consultation as appropriate, determine that the treatment measures have been completed to their
satisfaction.

TO: Responsible Agencies, Interested Parties, and Organizations SUBJECT: City of Manteca Central Trunk Sewer Project – City of Manteca The City of Manteca (City) is the California Environmental Quality Act (CEQA) Lead Agency for the proposed City of Manteca Central Trunk Sewer Project (Proposed Project). The City has directed the preparation of an Initial Study/Mitigated Negative Declaration (IS/MND) in compliance with CEQA.

Project Location: The City of Manteca Central Trunk Sewer Project (Project) Area consists of an area approximately 0.8 mile in length and 40 feet wide for the proposed new segment of sewer line within the City. The Project Site is located within Section 31, Township 1 South, Range 7 East, Mount Diablo Base and Meridian, as depicted on the 1994 minor revised edition of the 1980 photorevised edition of the 1952 U.S. Geological Survey Manteca, California 7.5-minute quadrangle.

Project Description: The Central Trunk Sewer Replacement Project (Project) consists of the replacement of an existing 36-inch diameter sanitary sewer trunk line that is deteriorated and aged connecting to the Union Road Lift Station (URLS) located within the Parks Department Corporation Yard. The new 36-inch trunk sewer line will be approximately 4,300 LF of 36-inch PVC SDR 26 pipe.

The existing lifting station will be decommissioned in the future by others. The new sewer line will begin downstream near the newly constructed subdivision off the Airport Road and extend eastward through the Kaiser Development, crossing the canal, through the Manteca Park Golf Course, continuing under the Parks Department Corp Yard and tie-in to the URLS at an existing sewer manhole.

Findings/Determination: They City of Manteca has reviewed and considered the proposed project and has determined that the project will not have a significant effect on the environment with the incorporation of mitigation measures, as supported by evidence provided in the Initial Study. The City of Manteca hereby prepares and proposes to adopt a Mitigated Negative Declaration for this project.

IS/MND Document Review and Availability: The public review and comment period for the Draft IS/MND will extend for 30 days starting April 24, 2026 and ending May 25, 2026. Draft IS/MND can be viewed and/or downloaded at the following website:

Lead Agency: City of Manteca (City)
Project Location: The City of Manteca Central Trunk Sewer Project (Project) Area consists of an area approximately 0.8 mile in length and 40 feet wide for the proposed new segment of sewer line within the City. The Project Site is located within Section 31, Township 1 South, Range 7 East, Mount Diablo Base and Meridian, as depicted on the 1994 minor revised edition of the 1980 photorevised edition of the 1952 U.S. Geological Survey Manteca, California

7.5-minute quadrangle.

The existing lifting station will be decommissioned in the future by others.

The new sewer line will begin downstream near the newly constructed subdivision off the Airport Road and extend eastward through the Kaiser Development, crossing the canal, through the Manteca Park Golf Course, continuing under the Parks Department Corp Yard and tie-in to the URLS at an existing sewer manhole.

Public Review Period: April 24, 2026 to May 25, 2026
Mitigation Measures Incorporated into the Project to Avoid Significant Effects:

Biological Resources
BIO-1: Special-Status Plant Habitat Avoidance. The following measures shall be implemented to avoid impacts to Special-Status Plant Habitat within the pipeline alignment:
 A special-status plant survey shall be conducted according to California Department of Fish and Wildlife (CDFW), California Native Plant Society, and U.S. Fish and Wildlife Service (USFWS) protocols prior to Project ground-disturbing or vegetationdisturbing activities within undeveloped areas. The survey shall be conducted by a qualified biologist (as defined per agency protocols) throughout all potential habitat for special-status plants within the Project Site and a 15-foot buffer. The survey shall be timed according to the identifiable period for special-status plant species with potential to occur (typically the blooming period). To the extent feasible, known reference populations shall be visited prior to the survey to confirm target species are evident and identifiable at the time of the survey. If no special-status plants are Draft Initial Study and Mitigated Negative Declaration
ECORP Consulting, Inc. 1-2 April 2026
City of Manteca Central Trunk Sewer Project 2025-144
found and the survey is still considered recent as per CDFW and USFWS protocols at the time of Project implementation, no further measures pertaining to special-status plants are necessary. If a special-status plant is identified within or adjacent to the Project Site, the following shall apply.
 An impact assessment shall be made by a qualified biologist to determine whether Project-related activities would be significant such that they would have the potential to eliminate, substantially reduce the number of, or restrict the range of the special-status plant species, and/or conflict with any local policies or ordinances protecting special-status plant species. If impacts are determined to be less than significant, no further measures are needed.
 If potential impacts are determined to be significant, then a no-disturbance buffer shall be established around special-status plant populations to be avoided within or adjacent to the Project Site. The no-disturbance buffer shall include the extent of the avoided special-status plants (as determined by a qualified biologist during an appropriate time to identify the plants immediately preceding construction) plus a minimum 15-foot buffer. The avoidance area shall be clearly demarcated in the field and demarcation shall be maintained for the duration of Project construction. No vegetation-disturbing or ground-disturbing activities shall occur within the avoidance area.

BIO-3: Nesting Birds. If construction is scheduled during the nesting season (typically February 1– August 31, and as early as January 1 for raptors), a qualified biologist shall conduct a preconstruction nesting bird survey within 14 days prior to the commencement of Projectrelated activities to identify active nests that could be impacted by construction. The survey shall be conducted within the Project Site and a 500-foot buffer for raptors and a 100-foot buffer for other birds, where accessible. If there is a lapse in Project-related work of 14 days or longer, the survey must be repeated prior to resuming Project activities. If active nests are found, a no-disturbance buffer shall be established around the nest. A qualified biologist shall establish a buffer distance. The buffer shall be maintained until the nestlings have fledged (e.g., are capable of flight and become independent of the nest), to be determined by a qualified biologist. The avoidance buffer can be removed, and no further measures are necessary once the young have fledged or the nest is no longer occupied, as determined by a qualified biologist.

BIO-4: Burrowing Owl. A qualified biologist shall conduct a take avoidance preconstruction survey according to the Staff Report on Burrowing Owl Mitigation. If active/occupied burrows are detected, a no-disturbance buffer shall be established around the burrow. The buffer distance shall be established in coordination with CDFW.

BIO-5: Swainson’s Hawk. If construction is scheduled during the Swainson’s hawk nesting season (March 1 to August 31), then, a qualified biologist shall conduct a survey for Swainson’s hawk nesting activity within a 0.5-mile distance surrounding the Project Site. The qualified biologist shall conduct surveys according to the Recommended Timing and Methodology for Swainson’s Hawk Nesting Surveys in California’s Central Valley or, if proposing an alternate survey methodology, shall submit the proposed survey timing and methods to CDFW for review and written approval prior to the initiation of surveys. If there is a lapse in Projectrelated work of 14 days or longer, the survey must be repeated prior to resuming Project activities. If Swainson’s hawk nesting activity is observed during the survey, an avoidance buffer shall be established by a qualified biologist in consultation with CDFW. The avoidance buffer shall be maintained while the nest is active.

BIO-6: Western Red Bat. Tree trimming/removal shall occur outside of the bat maternity season (April 15 through August 31), as feasible.

BIO-7: Aquatic Resources. Construction in this area will take place in one phase and will be completed before the irrigation ditch is used to convey any water.

 If the professional archaeologist determines that the find does represent a cultural resource from any time period or cultural affiliation, the archaeologist shall immediately notify the lead agencies. The agencies shall consult on a finding of eligibility and implement appropriate treatment measures, if the find is determined to be a Historical Resource under the California Environmental Quality Act (CEQA), as defined by CEQA or a Historic Property under Section 106 of the National Historic Preservation Act, if applicable. Work may not resume within the no-work radius until the lead agencies, through consultation as appropriate, determine that the site either: 1) is not a Historical Resource under CEQA or a Historic Property under Section 106; or 2) that the treatment measures have been completed to their satisfaction.
 If the find includes human remains, or remains that are potentially human, they shall ensure reasonable protection measures are taken to protect the discovery from disturbance (Assembly Bill [AB] 2641). The archaeologist shall notify the San Joaquin County Coroner (per § 7050.5 of the Health and Safety Code). The provisions of § 7050.5 of the California Health and Safety Code, § 5097.98 of the California Public Resources Code (PRC), and AB 2641 will be implemented. If the coroner determines the remains are Native American and not the result of a crime scene, the coroner will notify the Native American Heritage Commission (NAHC), which then will designate a Native American Most Likely Descendant (MLD) for the Project (§ 5097.98 of the PRC). The designated MLD will have 48 hours from the time access to the property is granted to make recommendations concerning treatment of the remains. If the landowner does not agree with the recommendations of the MLD, NAHC can mediate (§ 5097.94 of the PRC). If no agreement is reached, the landowner must rebury the remains where they will not be further disturbed (§ 5097.98 of the PRC). This will also include either recording the site with NAHC or the appropriate Information Center; using an open space or conservation zoning designation or easement; or recording a reinternment document with the county in which the property is located (AB 2641). Work may not resume within the no-work radius until the lead agencies, through consultation as appropriate, determine that the treatment measures have been completed to their satisfaction.

PALEO-1: Discovery of Unknown Resources. If any paleontological resources (i.e., fossils) are found during Project construction, construction shall be halted immediately in the subject area, and the area shall be isolated using orange or yellow fencing until the City is notified and the area is cleared for future work. A qualified paleontologist shall be retained to evaluate the find and recommend appropriate treatment of the inadvertently discovered paleontological resources. If the City resumes work in a location where paleontological remains have been discovered and cleared, the City will have a paleontologist onsite to confirm that no additional paleontological resources are in the area.
