I. RECOMMENDATION:
Council Approval of a Proposal and further authorize the Assistant City Manager to Execute a Task Order with the City Engineer, MKN & Associates, Inc. and LSA Associates (Environmental), (serving as Sub-Consultants) to provide Environmental Review, Design and Construction Engineering services for a New Sewer Lift Station and Force Main at Lost Gatos Creek South of Gregory and Hannah Way.
II. BACKGROUND:
The City currently has an existing siphon system operating at almost maximum capacity with no room for future development north of Los Gatos Creek. The project will provide for a new sewer lift station and force main to replace the existing older siphons. This will ensure that the City can accommodate future developments serviced by the existing sewer collection system. Currently the siphon system gravity feeds sewer to the wastewater plant through two pipelines under the creek and to the headworks at the plant.
III. DISCUSSION:
The City Engineer, in conjunction with MKN, will conduct an analysis of the existing siphon system and design a new lift station with force main to not only eliminate the current issues plagued by the existing system but ensure that future development may be served by these improvements so that the City is not restricted from growing due to lack of infrastructure. LSA will provide the environmental review (CEQA) documentation support to ensure compliance with state and federal regulations. A copy of scope of work has been attached for the Councils review.
The project is expected to take approximately 1 year from task order execution. It will take about 4-5 months for environmental review and design and roughly 4 months for construction.
IV. ALTERNATIVES:
- Do not approve and authorize the execution of above task orders - staff does not recommend as this is necessary to ensure reliability for future development.
V. FISCAL IMPACT:
The total authorization is $175,046.00 with the following breakdown:
City Engineer: $32,600.00
MKN & Associates: $105,886.00
LSA Associates: $36,560.00
The costs associated with this project will be paid from sewer impact fee proceeds and additional sewer enterprise project funds as needed. |
