HomeMy WebLinkAboutItem 6f - Authorization to Submit an Application for Proposition 1 IRWM Round 2 Implementation Grant Item 6f Department: Utilities Cost Center: 6004 For Agenda of: 9/16/2025 Placement: Consent Estimated Time: NA FROM: Aaron Floyd, Utilities Director Prepared By: Nick Teague, Water Resources Program Manager SUBJECT: AUTHORIZATION TO SUBMIT AN APPLICATION FOR PROPOSITION 1 INTEGRATED REGIONAL WATER MANAGEMENT (IRWM) ROUND 2 IMPLEMENTATION GRANT RECOMMENDATION 1. Adopt a Draft Resolution entitled, “A Resolution of the City Council of the City of San Luis Obispo, California, approving the application for grant funding from the Proposition 1, Round 2 Integrated Regional Water Management Implementation Grant” (Attachment A); and 2. Authorize the Director of Utilities, or his designee, carry out the City’s responsibilities under the funding agreement and to sign the funding agreement for the Implementation Phase of the Project and any amendments thereto , on behalf of the City. REPORT-IN-BRIEF The City’s Groundwater Contamination Characterization Project Implementation Phase will provide added resiliency to the City’s water resources, while also removing PCE contamination from the groundwater within the basin. Through various grant agreements and amendments and City Council authorizations, the project budget has expanded to meet project needs. The current project budget is $11,175,379, including $7,782,800 in grant funding and $3,392,579 in City funding. The latest engineering estimates have identified the need for an additional $1.8 million to complete the construction phases of the project. While staff are planning to complete the Monitoring Well Project (Phase 1) and Well Drilling Project (Phase 2), carry over remaining contingencies from those projects into the budget for the Well Equipping Project (Phase 3), and break Phase 3 into a base bid and an additive alternates to ensure the City has the flexibility to deliver a complete project within the available budget, staff are also looking for supplemental funding. As such, staff are requesting authorization to apply for up to $1 million in funding through the Proposition 1, Round 2 Integrated Regional Water Management Implementation Grant. Page 227 of 615 Item 6f POLICY CONTEXT The Groundwater Contamination Characterization Project Implementation Phase (Implementation Phase) aims to design and equip groundwater wells with treatment systems capable of removing tetrachloroethylene (PCE) contamination, and to put the City’s available groundwater to beneficial use as a drinking water source while removing PCE contamination from local groundwater supplies. The Implementation Phase is consistent with the City’s adopted General Plan Water and Wastewater Element (WWE) Goals A 2.1 and A 3.1 as providing an additional reliable water supply source helps to ensure a long-term, reliable water supply and manages the City’s water resources to meet both current and future water demand associated with development envisioned by the General Plan. Specifically, Policy A 3.2.3 states that “the City will continue to use groundwater to enhance the resiliency of the City’s water supply portfolio”. Under Section 740 of the Financial Management Manual (Grant Management Policy), Council approval is required for all grant applications in excess of $5,000. DISCUSSION Background Use of available groundwater resources would improve resiliency in the City’s water supply portfolio. Based on estimates published in the San Luis Obispo Valley Basin Groundwater Sustainability Plan, the City anticipates about 700 acre-feet of groundwater is available for use each year. The City does not currently use groundwater as a drinking water source but considers groundwater as a valuable water resource that will help the City meet its future water supply resiliency goals. Local groundwater quality sampling has documented areas of the San Luis Obispo Valley Groundwater Basin underlying the City that have localized groundwater contamination from PCE. PCE contamination restricts the City’s use of groundwater as a source of drinking water and must be treated before the City can utilize this resource. PCE is a chemical that is typically associa ted with dry cleaners, textile operations, and metal degreasing activities. The origin of the contamination remains unknown; however, it is not believed to be from a facility owned by the City of San Luis Obispo. In July 2020, the City received a $1,996,5 75 grant through Round 1 (Planning Phase) of the State of California Proposition 1 Groundwater Grant Program to study PCE contamination of the groundwater basin. The State’s program provides funding for grants and loans for projects that prevent and clean up contamination of groundwater that serves, or will serve, as a source of drinking water. A detailed understanding of the extent of PCE contamination and remediation options were necessary steps in fully utilizing the City’s ground water supplies. The total Planning Phase cost including the City’s local match was over $2 million. The Planning Phase of the Groundwater Contamination Characterization Project, including completion of a Remedial Investigation Report (PCE Plume Characterization Project Summary), Feasibility Study Report for the PCE Plume Characterization Project, and submittal of all documentation required by the State Water Resources Control Board (SWRCB) for reimbursement, was completed April 12, 2023. Page 228 of 615 Item 6f In September 2021, staff submitted a conceptual proposal through the Proposition 1 Groundwater Grant Program indicating the City’s interest in additional grant funding for the Project’s Implementation Phase (Round 3 of the Proposition 1 Groundwater Grant Program). In April 2022, the SWRCB invited the City to submit a full grant application for the Implementation Phase of the Groundwater Contamination Characterization Project. The grant application for the Implementation Phase was submitted July 2022, and the refined estimated budget was $6,607,850. On March 13, 2023, staff received a preliminary grant award letter from the SWRCB in the amount of $5,877,765, the full amount requested in the grant application (Attachment B). The award of the grant from the SWRCB required a local match of $730,085. On August 30, 2023, the City received a memo from the SWRCB that informed the City that SWRCB waived the match requirement for the City’s Implementation Phase ($730,085; Attachment C). The grant agreement was signed and executed on February 14, 2024, funding the full project budget amount of $6,607,850 (as estimated in 2024) with grant funding. On December 18, 2024, the City requested additional grant funding through the Proposition 1 Groundwater Grant Program to cover increased costs for tasks primarily related to design, engineering, and construction of the new extraction wells and groundwater treatment facility. In February 2025, the SWRCB notified the City that it was awarded an additional $1,174,950 in grant funding to the Implementation Phase of the Groundwater Contamination Characterization Project. The grant agreement (Attachment D) was signed and executed on February 14, 2025, providing a total of $7,782,800 in grant funding. In March 2025, the City’s consultant, WSC, notified the City that they were projecting a need for additional funding to complete design-phase services and engineering support during construction. To clarify the scope of work needed to complete the project, and to avoid additional budget overruns, the City provided WSC with a request for proposal with a fixed-fee cost. In their proposal, WSC estimated that an additional $943,283 (for a total fee of $1,885,760) is needed to complete the full scope of work for professional engineering services needed during the Implementation Phase of the project and grant (Attachment E). Additionally, as WSC progressed through the engineering and design of the Implementation Phase, revised costs for the construction phases have increased above the original estimates. The estimated construction costs for all three phases of the project exceed the currently available funding by about $1.8 million. Accounting for construction contingencies, the plan is to complete the Monitoring Well Project (Phase 1) and Well Drilling Project (Phase 2), carry over remaining contingencies from those projects into the budget for the Well Equipping Project (Phase 3), and break the Well Equipping Project into a base bid and an additive alternates to ensure the City has the flexibility to deliver a complete project within the available budget. Part of that flexibility in Phase 3 will include value engineering, identification of a base bid construction scope, alternate materials that are more economical, and a strategy of additive alternates that can be implemented as the construction risk factors associated with unforeseen conditions are eliminated. Page 229 of 615 Item 6f Proposition 1 IRWM Round 2 Implementation Grant Senate Bill 1672 established the Integrated Regional Water Management (IRWM) Act in 2002, intended to promote collaborative and integrated management of water resources. Proposition 1 was established to provide funding toward the IRWM Program administered by the California Department of Water Resources (DWR). Under the IRWM program, a Regional Water Management Group (RWMG) is responsible for local water management planning efforts within each IRWM region. The San Luis Obispo County Flood Control and Water Conservation District (District) and County, together with other local agencies and organizations, formed the RWMG for the San Luis Obispo County IRWM region. The District serves as the lead agency in accordance with the IRWM Program Participants Memorandum of Understanding (MOU), conducts project/program solicitations and evaluations, and makes recommendations on grant funding allocations. On November 2, 2022, the County Board of Supervisors (Board) approved filing an application and entering into agreements for the Proposition 1, Round 2 IRWM Grant, identifying five projects recommended by the RWMG for funding (Attachment F). On May 18, 2023, DWR awarded $3,782,129 in grant funding to the San Luis Obispo Coun ty IRWM region based on the District’s application. The District, as grantee, executed a Grant Agreement with DWR on December 7, 2023 . Significant deviations in scope, a delay in construction, and a reduction in benefits for the Central Coast Blue project jeopardized the utilization of $1 million in Proposition 1 grant funds. In response, the District requested and received direction from the Board on July 8, 2025, to return to the Board with a proposed project, or suite of projects, to replace the Central Coast Blue project. Staff are requesting authorization from the City Council to apply for the full $1 million available through this grant opportunity, which would provide supplemental funding for full implementation of the Groundwater Contamination Characterization Project. Previous Council or Advisory Body Action The City Council authorized staff to prepare and submit a grant application for the Groundwater Contamination Characterization Project (Round 1 – Planning Phase) on February 5, 2019. On December 7, 2021, the City Council approved and authorized specifications for the Planning Phase of the Groundwater Contamination Characterization Project and award of the construction contract; staff preparation and submittal of the grant application for the Implementation Phase (Round 3) of the Project; funding for application preparation and a local match of a maximum of 10 percent of the total project cost; execution of grant application documents; and a Resolution entitled “A Resolution authorizing entering into a Funding Agreement with the State Water Resources Control Board and authorizing and designating a representative for Phase 3 of the Groundwater Contamination Characterization Project.” Page 230 of 615 Item 6f On May 16, 2023, the City Council approved and authorized the use of up to $1,142,579 of City funding for the local match requirement (that was required at that time, but later waived by the SWRCB), and any potential increases in costs related to California Environmental Quality Act (CEQA) compliance, construction, and materials costs and associated inflation; execution of required grant, consultant, and construction-related agreements; and change orders and contract agreements for the project, not to exceed a cumulative total of $7,020,344 (including $5,877,765 of grant funding). On March 4, 2025, the City Council approved the project plans and special provisions for the Groundwater Well Drilling Project (a component of the Groundwater Project); adopted a resolution recommending adoption of the Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program for the Groundwater Contamination Characterization Project; and authorized the City Manager to approve contract amendments for the project, not to exceed a cumulative total of $7,750,429. On May 5, 2025, the City Council authorized advertisement and award of the Monitoring Well Drilling Project (a component of the Groundwater Project) and authorized contract amendments for the project not to exceed a cumulative total of $8,925,379 ($7,782,800 grant funding, $1,142,579 City funding, based on the increase in grant funding approved by the SWRCB in February 2025). On June 17, 2025, the City Council adopted the 2025-26 Financial Plan, which included an additional $2,500,000 from the Water Fund’s Unreserved Working Capital account for the Groundwater Project. This brought the total project funding to $11,175,379, including $7,782,800 in grant funding and $3,392,579 in City funding. Public Engagement A public forum was held on December 10, 2024, at the Public Library meeting room. At the public forum, staff from the City and its consultants presented on this project, and additional forthcoming projects that will collectively result in new infrastructure, which will provide clean groundwater for use as a new water source for the City. As a result of the public forum, the Groundwater Contamination Characterization Project was highlighted in an article by the San Luis Obispo Tribune. ENVIRONMENTAL REVIEW On March 4, 2025, City Council adopted a Resolution to adopt the Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program for the Groundwater Contamination Characterization Project. This Initial Study/Mitigated Negative Declaration (IS/MND) was prepared for the “whole of the action” of the Groundwater Contamination Characterization Project, which includes the Groundwater Well Drilling Phase, a Monitoring Well Drilling Phase, and a Well Equipping Phase . The environmental review process complied with all requirements of the California Environmental Quality Act statute and guidelines, including but not limited to Native American tribal consultation, n oticing requirements, public circulation of the document, availability of the environmental Page 231 of 615 Item 6f document at the City Utilities Department office and the City website, and filing of the Notice of Determination (NOD). The recommended action does not change the scope of the project and is consistent with the previously adopted IS/MND and NOD. FISCAL IMPACT Budgeted: Yes Budget Year: 2025-26 Funding Identified: Yes Fiscal Analysis: The table below outlines the costs to complete the Groundwater Contamination Characterization Project within the available budget amounts that were authorized by City Council on March 4, 2025 and in the City’s 2025-2027 Financial Plan. Available Project Budget (CIP Account No. 2091506) Proposition 1 Groundwater Grant $7,782,800 Additional Funding (2091506)1 $3,392,579 Expenditures to date2 ($2,086,716) Total Budget Remaining $9,088,663 Estimated Construction Cost for Phase 1 – Monitoring Wells $582,090 Estimated Construction Cost for Phase 2 – Groundwater Well Drilling $829,740 Estimated Base Bid Cost for Phase 3 – Equipping $7,676,833 Estimated Additive Alternate Cost for Phase 3 - Equipping $1,802,167 Total Estimated Construction Costs (Phases 1 – 3) $10,890,830 The estimated costs for full project implementation exceed the currently available funding by about $1.8 million. The total potential award amount from the Proposition 1, Round 2 IRWM Implementation Grant is $1 million. If awarded, this additional funding will be used to fund costs associated with the project’s construction phases, including the Phase 3 additive alternate. Meanwhile, staff are planning to carry contingencies from the Groundwater Well Drilling and Monitoring Well projects into the budget for the Well Equipping Project. The total of the contingencies included in the Groundwater Well Drilling and Monitoring Well projects is $101,740. The Well Equipping Project will be broken into a base bid and an additive alternate to ensure the project’s base bid can be awarded within the currently available budget. The Well Equipping Project also includes contingencies equal to about $1.12 million. ALTERNATIVES Deny authorization to apply for grant funding. City Council could decide to deny authorization to apply for grant funding. If Council denies the recommended authorization, staff will continue to look for other opportunities for grant funding and supplemental funds. 1 Includes $1,142,579 previously allocated for this project and $2,250,000 recently approved by City Council in the City’s 2025-2027 Financial Plan. 2 Includes $943,283 needed to complete design-phase services and engineering support during construction. Page 232 of 615 Item 6f Without any supplemental grant funding the City will need to fund the remainder of the project from the Water Fund or risk not completing the project as described in the Proposition 1 Groundwater Grant Program agreement, which would result in non- compliance and potential recoupment of grant funding.

The Tetrachloroethylene (PCE) Plume Characterization Implementation Project (Project) has been approved for funding with a grant award of $5,877,765. The Project consists of preparing a fate and transport groundwater model of the PCE plume, siting and construction of 2 extraction and treatment wells, and installation of a minimum of 8 monitoring wells to monitor the long-term progress of treatment within the City of San Luis Obispo (City). The Project has been reviewed by technical experts from the State Water Resources Control Board’s (State Water Board) Division of Financial Assistance (Division), the Central Coast Regional Water Quality Control Board, and the State Water Board’s Division of Drinking Water. The technical experts concur that the Project, as proposed, should achieve the stated objectives and is eligible for funding per the GWGP Guidelines, as amended on February 2, 2021. Based on staff’s review of the City’s request for a reduced match, supporting information provided in the Full Proposal, and the GWGP Guidelines, Table 2, the City qualifies for a reduced match of eleven percent (11%) because one hundred percent (100%) of the Project benefits a Disadvantaged Community or Economically Distressed Area. Robin Guillot has been assigned as the Project Manager for this Project. You will receive an introductory email from an assigned Program Analyst with further information about roles and responsibilities, grant agreement development, invoicing, deliverables, performance measures, and reporting requirements. You will also be contacted by your assigned Project Manager to ensure that all conditions and comments are addressed Page 237 of 615 Mr. Floyd - 2 - prior to execution of the final grant agreement. We encourage your prompt response to any requests from our staff because unreasonable delays or failure to respond could result in withdrawal of this grant award. Your grant award is conditioned on the successful negotiation of a grant agreement . The agreement process will begin with the finalization of a scope of work and budget that is acceptable to the Division. The scope of work will be based on the Full Proposal; however, the Division may require changes to the scope of work and budget as part of the grant agreement negotiation process. Based on the technical review of the Full Proposal, staff have initially identified the following item(s) that will need to be addressed. Key information to be provided prior to execution of the grant agreement: 1. Additional documentation regarding monitoring requirements and a detailed description of the remediation technology intended to be used for the Project. 2. Documents omitted from the Full Proposal including an up-to-date Project Director Certification form signed by the City’s Authorized Representative. Thank you for your consideration in addressing these items with Division staff. We look forward to working with you on this Project. Please contact the assigned Project Manager, Robin Guillot, with any questions at (916) 319-8259, or Robin.Guillot@waterboards.ca.gov.

Technical reviewers from several state agencies scored each proposal according to the rubric in Appendix F of the GWGP guidelines. On February 9, 2023, the Deputy Director of the Division of Financial Assistance (DFA) approved staff’s recommendation to award funding for eight projects and to not award funding for the Central Coast Blue project (Attachment A). DFA issued funding award letters for the eight Round 3 projects approved for funding. On March 17, 2023, DFA issued a funding denial letter for the Central Coast Blue project (Attachment B). The following new developments occurred after the Deputy Director of DFA approved staff’s recommendation: 1.DFA received an urgent appeal letter from the City of Pismo Beach (City) regarding the funding determination for the Central Coast Blue project on March 23, 2023 (Attachment C). Staff met with the City in person on April 5, 2023, and again via Teams on April 25, 2023, to discuss the project and its nexus to the cleanup or prevention of groundwater contamination. The City initially asked for $35.7 million in its proposal, then reduced the request to $18.5 million in its appeal letter. Most recently, in an email dated May 24, 2023, the City asked DFA to reconsider an approval of $8 million in GWGP funding (Attachment D). 2.The GWGP Guidelines were amended on May 2, 2023, to allow the Deputy Director of DFA discretion to completely waive the match requirements for Round 3 projects that benefit disadvantaged communities (DACs) and severely disadvantaged communities (SDACs), to the extent authorized by statute. Page 241 of 615 Joe Karkoski - 2 - ANALYSIS: REVISED FUNDING RECOMMENDATION FOR CITY OF PISMO BEACH’S CENTRAL COAST BLUE PROJECT DFA staff have re-evaluated the City’s proposed Central Coast Blue project (Project) and concluded that the Project is eligible for GWGP funding, and recommend providing $8 million in Prop 1 GWGP funding. By statute, projects that prevent contamination of groundwater that has served, or serves, as a source of drinking water are eligible. (Wat. Code, § 79771.) This project would prevent groundwater contamination that has served, and serves, as a source of drinking water by providing groundwater recharge to protect against contamination. Under the GWGP Guidelines, projects that provide groundwater recharge to prevent or reduce contamination of municipal or domestic wells, or that consist of groundwater injection to prevent seawater intrusion, are specifically listed as eligible project types. (GWGP Guidelines, § 4.4, subds. d and e.) Although the available information indicates that the communities’ voluntarily reduced pumping has reduced the likelihood of seawater intrusion, seawater intrusion would cause substantial adverse impacts to this water supply. Based on the eligibility criteria in the statute and GWGP Guidelines, the Project is eligible. Staff have determined that $8 million in funding is appropriate, but not the full requested amount of $35.7 million, based on the following considerations . The City and other local governments have successfully forestalled the immediate threat of groundwater degradation because the City and its partner agencies have diligently conserved water and reduced their groundwater pumping rates. As a result, the Project scored lower than the other proposals evaluated for Prop 1 GWGP funding. As discussed in the next section, there are insufficient remaining Prop 1 GWGP funds to cover the entire $35.7 million request. However, DFA staff have determined that the benefits of the project are significant enough to justify a GWGP grant. Future precipitation is unpredictable. During critically dry years, dwindling surface water supplies may force the City and other local governments to increase pumping rates, resulting in overdraft of the groundwater basin. The Project aims to prevent situations like this from happening. Additionally, the potential for the Project to enhance local water supply reliability and address the urgent need for an alternative water supply cannot be overlooked. The Project supports the priorities of Proposition 1 by enhancing water supply reliability (Wat. Code, § 79771(b)(3)), promoting groundwater recharge (Wat. Code, § 79771(b)(4)), and by allowing California to adapt to changing hydrologic conditions brought on by climate change (Wat. Code, § 79770). The project also aligns with California’s Water Supply Strategy and conforms with Executive Order N-3-23. Therefore, staff recommend providing $8 million in Prop 1 GWGP funding for the Central Coast Blue Project. Page 242 of 615 Joe Karkoski - 3 - ANALYSIS: MATCH WAIVERS The Prop 1 GWGP Guidelines set aside funds for projects benefiting DACs and SDACs as required by statute. The rest of the funds may be used for any projects eligible for Prop 1 GWGP, regardless of disadvantaged status (generic funds). The set-aside funds for projects benefitting DACs were exhausted after the initial award of Round 3 projects, and only one Round 3 project benefits an SDAC. Waiving the match requirement for eligible Round 3 projects would enable the GWGP to commit an additional $6.2 million from the generic funds and $1 million from the SDAC set-aside funds. CONCLUSIONS If the Deputy Director of DFA approves the $8 million request from the City and waives the match requirement for all eligible Round 3 DAC and SDAC projects, there would be $13.3 million remaining in generic funds, and $20.8 million left in the SDAC set-aside. These funds may be used to fund additional cost increases for existing projects, or to fund new drinking water treatment or wastewater projects that serve SDACs. STAFF RECOMMENDATIONS Staff recommends the following: 1. Award GWGP funds for the Central Coast Blue Project and waive match for all Round 3 projects that serve DACs and an SDAC that are eligible for the match waiver (a total of five projects) as shown in Table 1. One DAC project would not qualify for match waiver, as explained in the footnote. The non-DAC projects do not qualify for a match waiver under the amended Guidelines . $635,900,000 $20,800,000 $13,300,000 Prop 1 GWGP Funds Remaining After Waiving Match and Funding Central Coast Blue Committed SDAC Set-Aside Remaining Generic Funds Remaining Page 243 of 615 Joe Karkoski - 4 - TABLE 1 – GWGP Round 3 Revised Funding Recommendations Applicant Proposal Title DAC Status Funding approved 2/9/23 Match waiver Revised funding amount City of Dinuba Wellfield Groundwater Quality Improvement and Sustainability Project SDAC $9,541,601 Waive $10,611,819 City of Turlock Downtown Turlock PCE Project DAC $14,640,045 Waive $17,269,997 City of El Monte* Former Crown City Plating Site DAC $1,901,250 Do not waive $1,901,250 (No change) San Gabriel Basin Water Quality Authority Whitmore Street Groundwater Remediation Facility Expansion Implementation DAC $1,850,735 Waive $3,701,470 City of Modesto Municipal Groundwater Supply Contamination Prevention and Cleanup DAC $8,445,035 Waive $9,434,145 City of San Luis Obispo PCE Plume Characterization DAC $5,877,765 Waive $6,607,850 Alameda County Water District Brackish Groundwater Reclamation Project Non- DAC $2,205,094 Do not waive $2,205,094 (No change) United Water Conservation District Phase 1 Pumping of Coastal Brackish Groundwater Wells to Control Seawater Intrusion, Oxnard Basin Non- DAC $8,449,062 Do not waive $8,449,062 (No change) City of Pismo Beach Central Coast Blue Non- DAC $0 Do not waive $8,000,000 Totals: $52,910,587 $68,180,687 *The City of El Monte’s project, while serving a DAC, would not be eligible for a match waiver under present circumstances. Water Code, section 79771(c), prohibits funding to be used to pay any share of the costs of remediation recovered or recoverable from responsible parties . Under current circumstances, 54% of the project funds appear to be recoverable from a viable potentially responsible party, the property owner. 2. GWGP staff should notify Round 3 applicants that will be affected by the approval of a complete waiver of match requirements. 3.

In 2020, WSC helped the City secure a $2 million Proposition 1 Groundwater Planning Grant to delineate the extent of PCE plume so a remedial action plan for cleanup of the aquifer could be prepared. Upon completion of the initial work funded by the planning grant, WSC helped the City secure a $6.6 million Proposition 1 Groundwater Implementation Grant to construct a monitoring well network, drill and equip a new extraction well, equip an existing well, and construct a new granular activated carbon wellhead treatment system. Once constructed, the Project will be able to provide approximately 10% of the City’s water supply, increasing the reliability and resiliency of the City’s water supply portfolio. Project Approach WSC’s approach to successful Project delivery is based on continued collaboration and partnership with the City’s team, a renewed focus on project management, and the commitment and expertise of our team members. Project needs and priorities have evolved since the initial planning efforts, and our team has demonstrated its flexibility to adapt to these changing conditions while advancing Project goals and meeting schedule milestones. As we complete design and transition into the bidding and construction phases, coordination between WSC’s project manager and the City’s project manager will be critical to advance Project priorities while working within budget and schedule constraints. WSC’s team includes key staff members who have been involved in the Project since the initial planning and design efforts and who have an in-depth understanding of the Project and grant requirements. Our team will be supported by one of our most experienced project managers, Justin Pickard, and two of our most experienced QA/QC leads, Jeff Lawrence and Joe Kingsbury. The combined technical and professional capabilities of our staff will help ensure the successful delivery of the Project in accordance with the grant requirements.
