4. Authorize the City Manager or designee to execute all contracts and associated documents, subject to City Attorney approval.
BACKGROUND
On October 13, 2020, the City Council approved a five-year Memorandum of Agreement (MOA), and cost sharing between the City of Santa Clarita (City), Los Angeles County (County), and the Los Angeles County Flood Control District (Flood Control District) to develop and implement the Coordinated Integrated Monitoring Program (CIMP) and Enhanced 10 Packet Pg. 157
Watershed Management Plan/Watershed Management Program (EWMP/WMP). These documents are required for compliance with the Municipal Stormwater National Pollutant Discharge Elimination System Permit (NPDES Permit).
After a competitive process, the City Council awarded two, three-year contracts with up to two one-year extensions on June 22, 2021. One contract is for water quality monitoring to Tetra Tech Inc. (Tetra Tech) in the amount of $910,993. The second contract is for NPDES Permit compliance and reporting to Larry Walker Associates in an amount of $627,594. Although the City administers the contracts related to this program, it is only responsible for 39 percent of the associated costs. The remaining 61 percent is the responsibility of Los Angeles County.
This item for City Council consideration is a request to amend the existing MOA between the City, County, and Flood Control District, in addition to the related contracts with Tetra Tech and Larry Walker Associates.
Larry Walker Associates
The Los Angeles Regional Water Quality Control Board approved a new NPDES Permit that became effective on September 11, 2021. This new version of the NPDES Permit doubled the reporting requirements that are the subject of the MOA. The requirement to increase reporting was not known prior to approval of the current MOA. These changes doubled reporting frequency and increased data collection and analyses that are performed with the Larry Walker Associates contract. A proposal from Larry Walker Associates for the increased scope is attached.
Tetra Tech
The new version of the NPDES Permit also required new monitoring obligations and changed the way water quality monitoring is used to determine compliance. These changes have resulted in more stringent reporting, water quality requirements, and source investigations. The changes require increased water quality investigations that are performed with the Tetra Tech contract.
The City and County have made considerable progress in dry weather water quality from the storm drain system. However, there have been difficulties in addressing intermittent, dry-weather sources of bacteria. In order to address this concern, the new NPDES Permit requires a revised approach, focused on targeted and aggressive source identification and removal of dry weather flows. This approach requires amending the Tetra Tech contract to include a Comprehensive Human Waste Source Reduction Strategy (CHWSRS).
The CHWSRS is a study and abatement program to identify high risk human sources of bacteria and abate them if found. This effort will start with assessing the drainage area to MTD 1510 (drainage map attached) to identify and abate human sources of contamination that pose the greatest risk to water quality. It will be important to investigate additional drainage areas as a result of the more stringent bacteria requirements. Examples of abatement actions that could be identified and implemented through the CHWSRS may include enforcement or removal of leaking septic tanks; repair or replacement of leaking sewer pipes by the Sewer Maintenance District; or addressing encampments of persons experiencing homelessness near the monitoring 10 Packet Pg. 158
station. A proposal from Tetra Tech for the increased scope is attached.
Staff proposes to amend the Tetra Tech contract to implement CHWSRS, the Larry Walker Associates contract to address reporting and data collection, and MOA amendments to address these issues.
ALTERNATIVE ACTION
Other action as determined by the City Council.
FISCAL IMPACT
With the requested amendments referenced in the recommended action, there will be adequate funds in the existing budget appropriations.

Scope of Work for
CHWSRS Work Plan Development and Investigation Implementation
INTRODUCTION
The Upper Santa Clara River (USCR) Watershed Management Group (WMG) has faced multiple challenges achieving recreational water quality standards in the USCR and wasteload allocations within the Santa Clara River Bacteria TMDL (Bacteria TMDL). To support existing efforts conducted under the USCR Watershed Management Plan (WMP) and better protect public health and support recreational beneficial use goals, the USCR WMG began developing a Comprehensive Human Waste Source Reduction Strategy (CHWSRS) Work Plan (Plan) in 2021. The CHWSRS approach leverages recent advancements in the use of human markers and other diagnostic tools, as well as an enhanced focus on targeted source control efforts, to protect recreational beneficial uses and make progress towards compliance with associated water quality standards and Bacteria TMDL requirements. Strategy planning began in 2021 with an initial prioritization and revised WMP language to set the stage for a more effective pathway to improved public health through a reduction in high-risk human pathogen sources.
CHWSRS control measures conducted in parallel with implementation of the WMP will support USCR Bacteria TMDL compliance and long-term WMP goals through an adaptive management process that incorporates significant advances in the state of the science. Ongoing regulatory conversations within the region and the development of implementation approaches such as CHWSRS by the USCR WMG provide support for policies that implement more effective source control efforts. Completing the CHWSRS Work Plan on an accelerated timeline in 2023 will also support regulatory discussions with the Los Angeles Regional Water Quality Control Board on the Bacteria TMDL compliance schedule.
TECHNICAL APPROACH
The goal of CHWSRS is to support the WMG better align implementation actions with the goal of reducing pathogen health risk to recreators. The scope herein will build upon the preliminary catchment prioritization conducted in 2021 to develop a final CHWSRS Work Plan and initiate dry weather human waste source investigations (HWSIs) in Reach
6. This will be accomplished through the tasks outlined below.
TASK 1: PROJECT MANAGEMENT
Tetra Tech will follow established project management protocols and maintain regular communication with the City. The task includes project initiation, scheduling, monthly invoicing, and progress reports, coordination with the City, and other administrative tasks for the duration of this project. Mr. Tim Tringali will collaborate with Mr. Clint Boschen and Ms.
Shannon Quigley-Raymond to provide progress updates and attend monthly virtual coordination meetings. An initial kickoff meeting will be held with the City to discuss the project schedule, coordination requirements , draft Work Plan outline, and project objectives.
Deliverables:
• Monthly invoices and progress updates
• Kickoff call and monthly meetings

Comprehensive Human Waste Source Reduction Strategy Scope of Work 2 02/27/2023
TASK 2: CHWSRS WORK PLAN
The USCR CHWSRS Work Plan will prioritize identifying and abating high-risk human sources of pathogens to support the focus on bacteria as a water quality priority for the USCR WMG. Tetra Tech will leverage the annotated draft CHWSRS Work Plan outline developed in 2021 (included as Appendix A) and discussion during the kickoff call to further develop and finalize the plan. The CHWSRS Work Plan will focus only on Reach 6 and emphasize dry weather source identification and abatement activities.
Tetra Tech will incorporate additional data and complete refinements needed to develop the Work Plan. Additional data from water quality monitoring conducted between July 2021 and December 2022 will be incorporated into the prioritization. In addition, refinements to the MS4 catchments and network based on feedback on the initial prioritization will be completed to develop the final Reach 6 prioritization and identify the prioritized catchments for HWSIs. Tetra Tech will also develop an ESRI ArcGIS Online map to accompany the Work Plan and provide easy access and navigation of the available data and layers. The GIS layers in the ArcGIS Online map will include MS4 network, major outfalls, inlets, water quality monitoring sites, and catchments.
Following the data additions and refined prioritization, Tetra Tech will develop a draft CHWSRS Work Plan. Following WMG review, Tetra Tech will incorporate requested updates and edits from the draft in the final Work Plan. Along with the clean final version, Tetra Tech will submit a track changes version with responses to comments in the document.
During the finalization of the Work Plan, a Sampling Analysis Plan (SAP) and Quality Assurance Project Plan (QAPP) will be developed for the program. The overall source investigation approach will include a range of traditional and non-traditional pathogen health risk indicators available to aggressively and effectively track and identify human waste sources of pathogens. Physical, bacterial, viral, and/or chemical markers may be used to support source identification efforts, and will be selected based on available knowledge for the areas of concern.
Deliverables:
• Draft Work Plan
• ESRI ArcGIS Online Reach 6 Catchment Maps
• Final Work Plan
• Draft SAP/QAPP
• Final SAP/QAPP
TASK 3: MEETING AND REGULATORY SUPPORT
During the investigation phase of the project, the WMG will be regularly informed of the status of the HWSI for each AOI by way of updates at monthly WMG CIMP meetings or separate meetings. Validated data will be summarized within a standard series of tables and charts and distributed to the WMG via the monthly meetings. It is assumed that up to eight meetings will be supported by Tetra Tech in the first year.
On an as-needed basis, Tetra Tech will provide the City support for discussions or responses to comments related to Bacteria TMDL compliance strategies. Tetra Tech will prepare presentations and provide content related to the HWSI progress, high-risk based approach to bacteria and participate in up to two Regional Board meetings on the CHWSRS Work Plan or Bacteria TMDL.
Deliverables:
• LA Regional Board regulatory engagement, comment, and meeting support • Up to eight presentations at monthly meetings
TASK 4: HUMAN WASTE SOURCE INVESTIGATIONS
Tetra Tech will initiate HWSIs following the framework outlined in the CHWSRS Work Plan and will investigate up to three dry weather AOIs. To begin, Tetra Tech will prepare a template reporting form (AOI Reporting Form) for each of

Comprehensive Human Waste Source Reduction Strategy Scope of Work 3 02/27/2023
the three targeted AOIs that will document existing information relevant to the AOI, support additional stakeholder information requests needed to inform planning for each HWSI, and provide a summary of the monitoring plan. The form will also be used for documenting the iterative progress of each AOI HWSI as field and laboratory data are generated.
From the information compiled, any needed modifications to the catchment delineations will be completed and AOI- specific monitoring plans will be finalized by Tetra Tech. The AOI monitoring plan will be documented in a simple and streamlined way within the AOI Reporting Form to facilitate easy communication with the City and WMG regarding the status of and approach to each HWSI. It is anticipated that up to three iterations of this plan will be needed for each AOI to generally reflect the following phases of the investigation: Receiving Water, Outfall, and Catchment Level 1. In addition, the maps developed as part of the CHWSRS Work Plan will be customized with AOI monitoring plan details in ESRI ArcGIS Online. An ESRI Field Maps form will be developed for data collection via the mobile app as part of the investigation. Data collected using the field form will include the status of flow at outfalls and connectivity of any outfall flow to downstream receiving waters.
Following the finalization of the AOI-specific monitoring plan, Tetra Tech will prepare a LACFCD Access Permit application as necessary and submit the corresponding permit fees to support the HWSI receiving water, outfall and catchment phases for the three AOIs. Tetra Tech will then proceed with phased (i.e., receiving water, outfall, and catchment) implementation, relying on the CHWSRS Work Plan-specified Action Levels to guide risk-based decision- making about subsequent steps of the HWSI. Tetra Tech has established a preliminary set of assumptions regarding the number of sample sites, monitoring events, HF183 analytical batches, and HF183 sample analysis rate for each individual phase of the HWSI. These assumptions are documented in Table 1. Monitoring activities for the Receiving Water, Outfall, and Catchment Levels are included in the Scope of Work. Due to the iterative nature of source investigations and the fact that the outcome of monitoring associated with each phase of the HWSI is unknown at this time, the assumptions documented in Table 1 will be closely monitored, and should changes be anticipated, Tetra Tech will provide recommended adjustments.

Notes:
1 Paired sampling for E. coli and HF183 will occur at all locations, with all E. coli samples analyzed. 2 75% of E. coli samples meet the USCR CHWSRS Work Plan trigger to analyze the paired HF183 samples. 3 65% of E. coli samples meet the USCR CHWSRS Work Plan trigger to analyze the paired HF183 samples. 4 Catchment Investigation levels 2-4 are not included in scope and f ee. E. coli and HF183 samples will be analyzed by contracted accredited analytical laboratories in accordance with specifications defined in the SAP/QAPP.
Upon receipt of analytical laboratory results, Tetra Tech will review the results for completeness and consistency with the Data Quality Objectives specified in the SAP/QAPP. Tetra Tech will coordinate with the laboratories regarding any data quality concerns. Tetra Tech will populate the AOI Reporting Forms with a brief Interim Data Summary upon completing the Receiving Water, Outfall, and Catchment Level 1 Phases for each HWSI (nine total). It is assumed that additional summaries will not be needed in subsequent catchment level phases based on decisions made in earlier phases with respect to the monitori ng results and to allow for timely progression of catchment level investigations. A final data summary will be provided via the AOI Reporting Form after the completion of each HWSIs with laboratory reports and data files in CEDEN-compatible format.

BACKGROUND
The current playground at Valencia Glen Park (VGP) was installed in 1997, and modifications to the swings were completed in 2018. The VGP Play Area project will replace the existing playground equipment and expand the overall footprint. The new playground design will provide an accessible play area that welcomes children and adults to interact, play, learn, and grow together. This project will remove barriers and offer play experiences that promote integrated play for residents of all abilities and further develop physical, cognitive, sensory, communication and social skills.
Moreover, this project exemplifies the City of Santa Clarita's (City) commitment to improving its residents' quality of life and supports the Building and Creating Community theme of Santa Clarita 2025. The focus area identified in the Parks and Recreation 5-Year Plan is to maximize accessibility by offering inclusive play elements and design principles for people of all ages and 11 Packet Pg. 171
abilities.
In May 2023, the City released a Request for Qualifications inviting interested firms to submit their qualifications for the design and construction of a new playground for VGP. The City received two submissions and determined that both design-build firms, Great Western Installations, Inc., and Landscape Structures, Inc., were qualified to undertake this project.
After finalizing the playground design parameters and characteristics, the City issued a Request for Proposal (RFP) inviting the two pre-qualified firms to submit their proposals for the design and construction of the new playground at VGP. The RFP solicited firms to identify their relevant experience on similar projects, provide evidence of qualifications, and demonstrate their approach for this design-build project.
The City received proposals from Great Western Installations, Inc., and Landscape Structures, Inc. The proposals were evaluated by a panel of City staff who ranked each proposal based on the following criteria:
• The content, format and completeness of the written proposal • Demonstrated understanding of the described project and scope of work • Design Build Entity experience on similar projects
• Submitted design concept with inclusive play elements and recommendations • Adherence to the performance criteria for delivering the best possible project • Perceived technical competence and creative ability
• Ability to provide the deliverables based on a work plan and project schedule that meets or exceeds the City’s project schedule
• Quality and professionalism of the proposal
• Total cost of services
• Overall best value to the City
Following the evaluation process, Great Western Installations, Inc., received the highest score as outlined below.
Rank Company Location Score
1 Great Western Installations, Inc. Logan, Utah 92.6
2 Landscape Structures, Inc. Delano, Minnesota 84.2
Per section 22164 of the California Public Contract Code, design-build contract awards are not subject to a low bid obligation, compared to the traditional design-bid-build method. Rather, they shall be awarded via a best value procurement methodology in addition to cost of services.
Great Western Installations, Inc., demonstrated an in-depth understanding of the project needs and provided a detailed scope of work and approach to the project. They analyzed the existing site conditions and identified vital design factors that must be addressed. Based on their design experience with similar projects, the completeness of their proposal, and their cost of services, staff recommends awarding the design-build contract to Great Western Installations, Inc., for a total contract amount of $999,070. At the completion of the design and before commencing construction, the design will be reviewed for design immunity purposes pursuant to Resolution 11 Packet Pg. 172
No. 19-6.
The requested contingency will cover any unforeseen issues or additional needs during the design and construction. The remaining funds will cover staff oversight related to construction and project management, public works inspection, labor compliance, and administrative costs.
ALTERNATIVE ACTION
Other action as determined by the City Council.
FISCAL IMPACT
Upon approval of the recommended actions, adequate funds will be available in the Fiscal Year 2023-24 budget to project expenditure account P1019203-516101 Community Development Block Grant (Fund 203) to support the recommended contract and project administrative costs.

BACKGROUND
The Final Tract Maps for Tract No. 51644-16 and Tract No. 51644-17, a location map exhibit of which is attached hereto, have been reviewed by City of Santa Clarita (City) staff and found to be in substantial conformance with the principles and standards required by the Unified Development Code and State Subdivision Map Act. On November 7, 2018, the Los Angeles County Department of Regional Planning approved the Revised Vesting Tentative Tract Map No. 51644-1. On November 12, 2019, the City Council approved the Tesoro del Valle Annexation (Master Case 19-115). This area was subsequently annexed to the City on November 14, 2022. The subject property on both maps is located within the Tesoro del Valle area, north of Tesoro del Valle Road.
Lots 90, 91, and 92 of Tract Map No. 51644-16 and lots 123 and 124 of Tract Map No. 51644-17 are lots to be developed as debris and desilting basins for flood control purposes. The offer of dedication in fee simple for these lots is being rejected on the map to limit the City’s liability until the improvements are constructed and completed to the satisfaction of the Public Works Director. Following acceptance, ownership of the basins will be transferred to Los Angeles County Flood Control District.
The Final Tract Map No. 51644-16 consists of a subdivision of 75.93 acres into 122 lots and allows for the construction of 89 single-family residential units, two private park lots, 24 open space lots, two public streets, and various private street and utility service lots.
The Final Tract Map No. 51644-17 consists of a subdivision of 100.06 acres into 153 lots and allows for the construction of 122 single-family residential units, 20 open space lots, and various 12 Packet Pg. 176
private streets and utility service lots.
The Final Tract Maps for Tract No. 51644-16 and Tract No. 51644-17 were reviewed to the satisfaction of the City Surveyor and the City Engineer and found to be in substantial conformance with the previously approved Tentative Tract map. The conditions of approval established by the County of Los Angeles and adopted by the City were also met and fees have been and/or will be paid as indicated on the attached Fact Sheets. Therefore, the Final Tract Maps are ready for City Council approval and acceptance of the dedications shown thereon.
Pursuant to Section 66474.1 of the Subdivision Map Act, a legislative body shall not deny approval of a final or parcel map if it was previously approved as a tentative map for the proposed subdivision and if it finds the final or parcel map is in substantial compliance with the previously approved tentative map.
ALTERNATIVE ACTION
Staff has not identified alternative actions that would conform to requirements set forth in the Subdivision Map Act.
FISCAL IMPACT
The public streets shown on the Final Tract Map for Tract No. 51644-16 will be dedicated to the City and will be constructed by the developer. The maintenance of this additional asphalt will have minimal impact on the City's street maintenance budget.
