DISCUSSION
Background
The Margarita Lift Station, and its associated 230 feet of six-inch cast iron force main, serves
properties east of South Higuera Street adjacent to Margarita Avenue and was put into service in
1971. At 45 years old, it is operating beyond its life expectancy. Due to the age and condition of
the lift station, budget for the design of a replacement station was identified in the Capital
Program in the 2013-15 Financial Plan. The City Council authorized a request for proposals and
the City Manager awarded a contract for design services to replace the lift station in November
2013 and March 2014, respectively. Construction funding for the project was identified in the
2015-17 Financial Plan, Capital Improvement Plan.
The existing Margarita Lift Station is located along the Margarita Avenue street frontage
adjacent to the Margarita Apartments which are owned and managed by the San Luis Obispo
Housing Authority (HASLO). The new Margarita Lift Station will be located on an easement
obtained by the City from HASLO. The City and HASLO collaborated on the project’s fencing,
lighting, sound attenuation, service access, and the connection of recycled water for irrigation on
the property. The old station will be abandoned and the property upon which it was located will
become part of the Margarita Apartments landscaping.
ENVIRONMENTAL REVIEW
This project is categorically exempt from the California Environmental Quality Act pursuant to
CEQA Guidelines section 15302 (Replacement or Reconstruction of existing structures and
facilities).

CONCURRENCES
The Public Works Department has reviewed the plans and special provisions and provided
comments that have been incorporated; Community Development concurs with the
environmental review findings.
FISCAL IMPACT
$950,000 was budgeted for design, easement acquisition, construction, and construction
management services from the Sewer Fund for this project in the 2015-17 Financial Plan (page
3-67 of the Capital Improvement Plan). Additional funding in the amount of $152,000 is required
to support updated cost estimates for construction and construction management services due to
the project’s complexity including limited site area and duration of equipment procurement. The
Engineer’s estimate for project construction is $762,000.
Original Project Budget $950,000
Increased Construction Estimate (including contingencies) $127,500
Increased Construction Management Estimate $24,500
Proposed Project Budget $1,102,000
Additional funding for the proposed project budget is recommended to come from Sewer Fund
Working Capital. The Sewer Fund Working Capital balance as of July 15, 2016 is $12,030,620.
ALTERNATIVES
Deny or defer approval to advertise. The City Council may choose to deny or defer the approval
to advertise this project. If Council elects to defer the project, Utilities would continue to work to
maintain the station in operable condition. Efforts already made to prolong the life of the station
include repairs to the floor of the sump pump due to leaks in 1995; cathodic protection to extend
the life of the structure in 1996; additional leaks were repaired on the floor and walls in 2010. If
the station is run to failure requiring emergency replacement, emergency construction costs and
impacts to the adjacent housing and the environment would be significant.
