Amendment
SUMMARY:

On August 10, 2026, the City Council approved a construction contract with Hale Construction, Inc. ( Hale) for the Lathrop Animal Center, CIP GG 23- 11 (Project).

Construction began in late September 2026.

In preparation for construction, staff identified a conflict between the proposed temporary sewer and storm drain connections and future Pacific Gas and Electric Company ( PG& E) infrastructure. The temporary connections must be eliminated and the permanent infrastructure constructed to maintain essential public services to the Project. Staff requested a proposal from Hale to construct the revised sewer and storm drain facilities for an amount not to exceed $ 1, 061, 715 plus a 15% contingency of $ 159, 258.

The Project also requires specialized construction engineering services, including Stormwater Pollution Prevention Plan ( SWPPP) services and inspection of topside and underground construction. Staff requested proposals from ENGEO, Inc. (ENGEO), under the City' smaster agreement for construction engineering services approved on August 5, 2025.

Staff recommend that the City Council approve Emergency Change Order No. 1 ( ECO No. 1) with Hale in an amount not to exceed $ 1, 220, 973 and approve the associated budget amendment. Staff also recommend that the City Council approve Task Orders No. 1-4 with ENGEO in a combined amount not to exceed $ 368, 500 to provide construction engineering services for the Project.

BACKGROUND:

On January 9, 2023, the City Council approved the creation of the Project. LDA Partners prepared the plans and specifications, and the Project was advertised for CITY MANAGER' SREPORT PAGE 2

bids on June 26, 2026. On August 10, 2026, the City Council approved a construction contract with Hale, and construction began in late September 2026.

The Project design included temporary sewer and storm drain connections behind the westerly sidewalk instead of installing the permanent, larger pipes in Stanford Crossing Drive. Those larger pipes are intended to serve future development in the Central Lathrop Phase 2 Specific Plan area ( CLSP Phase 2), north of Dos Reis Road.

As staff coordinated the Project' s electrical connections with PG& E, staff identified a spatial conflict between the proposed temporary sewer and storm drain connections and future PG& E service infrastructure. Accordingly, ECO No. 1 will replace the temporary connections with permanent, larger sewer and storm drain pipes in Stanford Crossing Drive to maintain essential public services to the Project.

Hale proposed to construct the revised sewer and storm drain facilities for an amount not to exceed $ 1, 220, 973. Because the facilities in Stanford Crossing Drive will also benefit future development in CLSP Phase 2, staff anticipates that the City will be reimbursed for the costs associated with ECO No. 1 when that area develops.

The Project requires specialized construction engineering services, including SWPPP services and inspection of topside and underground construction. The City maintains a master agreement with ENGEO for construction engineering services on City capital improvement projects. Staff requested proposals from ENGEO for the services needed to support this Project.

The proposed task orders and associated costs are:

Task Order Scope of Services
No. 1 SWPPP Services
No. 2 Topside Inspection Services
No. 3 General Underground Inspection
No. 4 Stanford Crossing Underground Insp.

Total Construction Engineering Services
Amount
68, 500
80, 000

Staff recommend that the City Council approve ECO No. 1 with Hale in an amount not to exceed $ 1, 220, 973, approve the associated budget amendment, and approve Task Orders 1-4 with ENGEO in a combined amount not to exceed $ 368, 500.

REASON FOR RECOMMENDATION:

ECO No. 1 is necessary to avoid conflicts with future PG& Einfrastructure and maintain essential public services to the Project. The proposed ENGEO task orders will provide SWPPP management and special inspectionsneeded to support ongoing construction.

APPROVE EMERGENCY CHANGE ORDER NO. 1 WITH HALE CONSTRUCTION, INC. AND TASK ORDER NO. 1-4 WITH ENGEO, INC. FOR LATHROP ANIMAL CENTER, CIP GG 23- 11 AND ASSOCIATED BUDGET AMENDMENT
FISCAL IMPACT:

Staff is requesting that the City Council approve a budget amendment totaling 1, 220, 973 for ECO No. 1, which includes the construction of the required infrastructure to maintain essential public services to the Project including water, sewer, and storm drain services. The costs are as follows:

Water:

Sewer:

Storm Drain:

Total:
113, 629
441, 856
665, 488
1, 220, 973
Future development will reimburse the City for its proportionate share of these infrastructure costs as development occurs.

Sufficient funds are available in the Water Operating Fund ( 5620) and Sewer Connection Fee Fund ( 6030) to cover their respective costs. However, the Storm Drain Connection Fee Fund ( 2280) does not have sufficient funds to cover the $ 665, 488 storm drain cost. Staff is therefore recommending that the General Fund ( 1010) temporarily fund the storm drain shortfall, with the understanding that future development will reimburse the City for its proportionate share.

Additionally, on January 9, 2023, the City Council approved Resolution 23- 5205, authorizing $ 7, 498, 000 for the Lathrop Animal Center. The Municipal Services Fund currently has sufficient funds to reduce the outstanding interfund loan by $ 665, 488.

This reduction will offset the amount of General Fund funding needed for the storm drain shortfall.

The following budget and accounting entries are required:

Decrease Interfund Loan Receivable

Description: This work is required to extend the roadway and underground utility network beyond the footprint of the active Animal Center construction site. Executing this scope at this time avoids future service disruptions to the Animal Center and adjacent municipal facilities, which would inevitably occur tithe roadway and utility work were deferred until a future commercial or residential developer assumed construction responsibility. Extending these critical • utilities concurrently with ongoing regional operations prevents costly retrofit operations and traffic/ utility downtime.
