City to Host Ribbon Cutting for New Wastewater Pump Station, Connector Path on Lomita Avenue

Join us on Monday, October 23, 2017 from 1 - 2 pm for a Ribbon Cutting Ceremony to mark the completion of the new Sutton Manor Pump Station and Bike Path Connector. Click here to see a map of the location of the ribbon cutting.

 

SASM and City of Mill Valley officials are set to mark the completion of a two-for-one infrastructure project that both upgrades a vital wastewater pump station and adds a paved, safer connector path to the Mill Valley-Sausalito Multi-Use Path from the busy Lomita Drive-Ashford Avenue intersection.

 

The event, to be held at the intersection of Lomita Drive and Ashford Avenue (adjacent to the Cat Clinic of Mill Valley), will include a ribbon-cutting ceremony by officials from the City Council, and the Sewerage Agency of Southern Marin (SASM), the joint powers agency that collects and treats wastewater for approximately 28,000 residents in the City, the Tamalpais Community Services District and the Alto, Almonte, Homestead Valley and Richardson Bay sanitary districts.

 

The nine-month project, approved in 2015, began as an opportunity to replace the more than 35-year-old Sutton Manor Pump Station, an antiquated piece of SASM’s vast infrastructure that had long been identified for replacement to better handle peak wet weather flow conditions and to provide a more substantial back-up power supply. The pump station is one of six such stations that SASM maintains throughout its sewer system.

 

SASM elected to relocate the pump station to an undeveloped site across Lomita Avenue. Over the course of seven months, workers constructed the $1.3 million state-of-the-art pump station. The majority of the pump station elements are below ground, with other equipment screened by a 6-foot-high redwood fence and landscaping.

 

SASM is in the midst of implementing its Wastewater Treatment Plant Master Plan (WWTP), a 30-year roadmap for SASM’s efforts to plan for expected new legal requirements, protect it from flooding due to 100-year flood events and sea level rise, deal with aging infrastructure, prepare for its future growth needs, incorporate sustainability initiatives and reduce the impact of the plant’s odor on its neighbors. The first phase of the Master Plan will renovate and rebuild essential treatment plant components at a cost of $20 million.

 

In the course of exploring the pump station project, City officials recognized that a dirt path adjacent to the pump station site had long been used as a connector path to and from the section of the Mill Valley-Sausalito Multi-Use Path that extends from East Blithedale Avenue to Vasco Court. That section of the path has long been a popular link for students who walk or bike to nearby Edna Maguire Elementary School, as well as a route for residents of the Alto-Sutton neighborhoods to other schools and nearby commercial destinations.

 

With that in mind, City Councilmembers, with the support and involvement of officials from the Safe Routes to Schools program and the City’s Bicycle Pedestrian Advisory Committee, urged the pump station overhaul to include paving the dirt path to codify the long-used connector between the neighborhood and the multi-use path. The SASM Board enthusiastically agreed and collaborated with the City to create a much improved paved pathway which opened to much appreciated neighborhood use before this school year.

 

With both the pump station and the connector path elements of the project completed, local officials look forward to marking this two-for-one infrastructure upgrade that benefits users both in the immediate Alto-Sutton neighborhood but also well beyond it.
