COUNCIL AGENDA REPORT
MEETING DATE: 04/07/2026
ITEM NO: 8
DATE: April 7, 2026
TO: Mayor and Town Council
FROM: Chris Constantin, Town Manager
SUBJECT: Authorize the Town Manager to Execute a First Amendment to the Agreement for Consultant Services with CSG Consultants, Inc., to Extend the Term of the Agreement
RECOMMENDATION: Authorize the Town Manager to execute a First Amendment to the Agreement for Consultant Services with CSG Consultants, Inc., to extend the term of the agreement for encroachment permit plan review and inspection services related to Comcast projects for a term of one year.

FISCAL IMPACT:

There is no fiscal impact associated with this action. This agreement is fully funded through applicant (Comcast) deposits collected by the Town for encroachment permit review and inspection services by the consultant (CSG). The Town issues Authorizations to Proceed to the consultant based on available deposit balances, ensuring that all consultant costs are fully reimbursed and that no General Fund or other Town funds are utilized.

The agreement includes a not-to-exceed amount of $500,000; however, expenditures are limited to funds received from Comcast, resulting in no net fiscal impact to the Town. This structure eliminates financial exposure to the Town by ensuring services are only authorized when sufficient third-party funding is available.

STRATEGIC PRIORITIES:

This project specifically supports the Town’s 2025-2027 Strategic Priorities Core Goals of Quality Public Infrastructure and Public Safety.

ITEM NO. 8.

PAGE 2 OF 3
SUBJECT: Consider Authorizing the Town Manager to Execute a First Amendment Extending the CSG Encroachment Review and Inspection Services – Comcast Contract
DATE: April 7, 2026
BACKGROUND:

Encroachment permits are used by the Town to control work in the public right-of-way and on Town property. Encroachment permit applications vary in scope from general maintenance activities, such as inspection of overhead electrical appurtenances from a bucket truck to installation of new facilities such as fiber optic lines buried along the side of the road.

Encroachment permit applications are required to ensure Town Codes are followed, and work in the right-of-way is done safely with proper traffic control that accommodates all modes of transportation through the work area.

The Town continues to receive and process a significant number of encroachment permit applications due to the expansion of new telecommunication technologies in the area, including fiber optic wired connections to homes.

On January 21, 2025, the Town Council authorized the Town Manager to execute an agreement with CSG Consultants to provide plan review and inspection services of the proposed Comcast encroachment permits. The original contract term will expire June 30, 2026.

DISCUSSION:

With the recent expansion of fiber optic technologies and infrastructure in the Town by multiple telecommunication companies, staff have observed an increase in encroachment permit applications both in quantity and scope. To ensure success in meeting the Town’s Strategic Priorities, the Town augmented the encroachment permit review process by using consultant services. Amending this agreement will provide staff with support to meet the continued demand for Comcast encroachment permit plan review and inspection services.

CONCLUSION:

Approval of this amendment will ensure the Town maintains timely and effective review and inspection of encroachment permit work in the public right-of-way, supporting public safety, infrastructure protection, and efficient service delivery. The cost of CSG’s services will be borne by Comcast. Therefore, authorization to amend this on-call consultant services contract with CSG will benefit the Town without financial impact.

COORDINATION:

This staff report has been coordinated with the Finance Department.

Gary Heap,
Town Engineer
Town of Los Gatos
41 Miles Avenue
Los Gatos, CA 95030
RE: Comcast Encroachment Permit Plan Review - Proposal
Dear Gary:

CSG Consultants, Inc. is pleased to present this proposal to assist the Town of Los Gatos with Plan Review for the Comcast Encroachment permit application.

Comcast proposes to install communication lines within the Town of Los Gatos Public Right-of-Way..

Work to be performed under this proposal will include the following:

Plan Review
1) Plan Review:

Review plans for conflicts with existing surface improvements.

Review plans for conflicts with existing utilities. Identify utilities that may require potholing prior to construction.

Review plans for consistency with Town trench resurfacing standards.

Confirm plans show appropriate repairs to other surface improvements (concrete, pavers, landscaping) where these improvements are impacted.
2) Prepare a comment letter for each review. Meet with staff and/or the applicant as needed to review comments and how comments will be addressed.
3) Complete subsequent reviews as needed.
4) Review traffic control plans and provide comment letters and meet with Town staff and Comcast as needed.
5) Attend other meetings as needed.

Sandra Meditch, P.E., will serve as the point of contact, oversee plan review work, and conduct QA/QC.

Fee
Our fee for performing the work described above will be on a time and materials basis, based on our 2024 Standard Fee Schedule. See attached.

ITEM NO. 8.
2 Inspection Services
CSG stands ready to provide inspection services if and when needed. Enforcing traffic control requirements and the permit provisions are vital on this type of work. Also working closely with the contractor to ensure all utilities are marked and trenches are backfilled according to project plans and difficult to arrive at a cost at this time. However, as a place holder we suggest the Town set aside $10,000 to be finalized upon the determination of the level of effort desired by the Town and number of working days dictated by the contract.

Thank you for considering CSG Consultants for this work. We look forward to working with you on this project. Please feel free to call Sandra Meditch at (650) 522-2629 if you would like to discuss this further.

Sincerely, _______________________________
