2 Memo: To: Town Council Los Altos Hills Fr: Allan Epstein RE: Wastewater System Management Consultant Date: June 18, 2014 The Town continues to have substantial difficulty in managing the Sewer System and has had this problem over a much extended period of time. Projects are not completed on time, subcontractors are not closely supervised, regulatory requirements are not being fully met and Sanitary System Overflows (SSO) are increasing. Some of these difficulties may be due in part to insufficient staffing and lack of expertise. The Council authorized a Senior Engineer in April 2012, however in the last 24 months the position has only been filled one quarter of the time and the Town is currently recruiting for this opening. The Town has attempted to fill this staffing shortfall with temporary help from CSG. Neither CSG nor the Publics Work Director are experts in Wastewater Systems. I recommend hiring a proven, experienced Wastewater System expert to review the Town's Sewer System and make recommendations. Budget not to Exceed $10,000. The Scope of the review: Provide a general review of Town sewer maintenance data, to a level that is sufficient to assess the current status of cleaning, repairs, and pipeline condition. If pump station inspections have been completed, this information will reviewed as well. Based on the information reviewed, review existing sewer-related activities, plans and budgets, and confirm whether the planned activities are appropriate. If not appropriate, make recommendations as to options that should be considered by the Town and how these activities would change the proposed budget. Discuss findings and recommendations with the Finance and Investment Committee and Council. Summarize findings and recommendations in a Technical Memorandum A qualified consultant, Vivian Housen PE, has been identified and some initial discussions have been held and she is available. Other consultants could be considered as well. Vivian Housen has over 25 years of experience in the planning, design, and management of water and wastewater infrastructure projects. She is a hands-on manager for programs and projects involving wastewater facility improvements, hydraulic modeling, master planning, utility asset management, and regulatory compliance. Vivian also assists agencies with interim management needs and improving O&M efficiencies. She is strategic and forward-thinking, and is recognized for her ability to build consensus among diverse organizations. She has demonstrated success delivering controversial programs significantly under budget. Her resume and map showing where she has worked in the Bay Area are attached.

Following adoption or readoption of the SSMPs, Vivian has provided management support to many of these agencies to ensure that ongoing maintenance activities meet or exceed SSMP requirements. Project Manager for Regulatory Compliance Support, Sewerage Agency of Southern Marin, Mill Valley, California. Vivian assisted the agency in the development of a Wet Weather Improvement Plan, which was a requirement of the wastewater treatment plant NPDES discharge permit. The plan identified activities in place by the agency and its upstream dischargers to reduce inflow and infiltration and reduce wet weather blending. Vivian is also assisting the agency in addressing requirements of a 2008 EPA Order for Compliance, and provides as-needed assistance on a variety of sewer-related issues, including recent development of a Private Lateral Replacement Ordinance. Asset Management Project Manager for Linear Asset Management Plan, West Bay Sanitary District, Menlo Park, California. Vivian is helping the District to document Level of Service objectives, develop a risk model using Microsoft Access that calculates Risk based on Likelihood and Consequence of Failure, and use this model to validate the District s capital improvement priorities. The risk model interfaces closely with the District s GIS-based computerized maintenance management system (CMMS), which uses Lucity software. The resulting report will serve as the roadmap for future rate-setting and infrastructure planning. Project Manager for Infrastructure Asset Management Plan, Ross Valley Sanitary District, San Rafael, California. Vivian completed a comprehensive infrastructure asset management plan for the District, within an accelerated timeline that was mandated by a Regional Board Cease and Desist Order. The evaluation began with development of Level of Service objectives, followed by evaluations of the system pump stations, pipelines, and force mains, and development and prioritization of needed improvements using a computerized risk model. The risk model was developed in MS Access for the project, and is customized to address the District s factors that influence Likelihood and Consequence of Failure. In addition to addressing capital needs, the plan provides updates to existing operations and maintenance procedures as recommended to reduce sewer system overflows. Project Manager for Conveyance System Reliability Improvements Project, Delta Diablo Sanitation District, Antioch, California. This project aggregated the District s asset information, completed gaps, and built an asset registry using GIS; developed level of service objectives and condition assessment protocols for linear assets and facilities, completed facility evaluations, developed a numerical risk- based prioritization model, and ran asset and condition data through the model to develop a prioritized capital improvement program. During the project, opportunities for operations and maintenance efficiencies were discussed and recommendations provided. Project Manager for Sewer Collection System Lifecycle Asset Management Project, San Francisco Public Utilities Commission, California. This multi-faceted effort provided support to City staff in assessing existing data and processes, identifying gaps, recommending sewer inspection and condition rating protocol, transitioning from current CMMS practices to a City-wide asset and maintenance management program, and developing criteria and a decision model to evaluate risk and consequence of failure for the collection system in support of a prioritized linear asset master plan.
