Adopt Resolution Authorizing City Manager to Execute Professional Services Agreement with Saracino Kirby Snow for Water Supply Planning Work, and Appropriate $90,000 MEETING DATEFebruary 5, 2003 PREPARED BY: Public Works Director RECOMMENDED ACTION: That Council adopt a resolution authorizing the City Manager to execute a professional services agreement with Saracino Kirby Snow for water supply planning work and appropriate funds. BACKGROUND INFORMATION: As the Council is aware, the City has been participating in various activities through San Joaquin County that could result in a surface water supply for Lodi. A key element of these efforts will be answers to the question "How will we use the water?" There are two fundamental concepts to consider and many, many details to be decided at some point. The two fundamental concepts are to treat the water for domestic purposes and use it as we do groundwater now, and the other is to participate in some type of groundwater conjunctive use project or develop other means of utilizing the water for non -potable water uses, such as landscape irrigation (which could include use of reclaimed water from the White Slough Water Pollution Control Facility) - Staff Proposes to begin a more detailed look at these options so when it comes time to make decisions on surface water, we will have a better idea as to the full cost and practicality of using surface water in Lodi. To be clear, we have no doubts that the City will have to make some use of surface water in the future to decrease our dependence on the overdrafted groundwater basin. State land use approval requirements are placing more emphasis on linking new development approval to water supplies. In addition to our involvement with the County and City of Stockton on the Mokelumne River Water & Power Authority, we have been in discussion with the Woodbridge Irrigation District about the possibility of obtaining a surface water supply from them. To this end, we requested a proposal from the consulting firm of Saracino Kirby now (SKS) to assist the City in this work. The work will include: * Assessing surface supply options, including direct use and groundwater recharge * Assessing feasibility of using non -potable or reclaimed water * identifying new development mitigations to increased groundwater use * Assisting City with Mokeiumne River supply activities The first three tasks will result in technical memoranda which will be presented to Council upon completion, During this process we anticipate making various public presentations, such as at service APPRovrD� CS KS ProfS�rvAcjmt WIV OV30/03 Adopt Resolution Authorizing City Manager to Execute Professional Services Agreement with Saracino Kirby now for Water Supply Planning Work February 5, 2003 Page 2 clubs and the various Chamber of Commerce committees, plus holding some public forums. Integrating a surface water supply with Lodi's groundwater system presents technical challenges which can certainly be overcome, However, the public understanding and acceptance is also very important, particularly when the cost of water service may be affected. The fifth "ask ($200,00), developing a groundwater model, may be needed, but staff recommends this task be deferred at this time. We wish to discuss this further with SKS before making a recommendation. The more detailed scope of work is attached. The consultant cost is estimated to be $76,000. We have added a significant contingency amount in the requested appropriation to cover public participation and meetings, plus additional work that may be needed to respond to questions/comments as the work progresses- FUNDING� Water Fund - $90,000 Funding Available: Finanoe—�Direct®r��� Richard .'rima, Jr. Public Works Director RCPf'pmf Attachment cc: Randy Hays, City Attorney Wally Sandelin, City Engineer Fran Forkas, WaterlWastewater Superintendent Saracino Kirby Snow CSKSPro'SorvAgml.

Proposal to Provide f2noeering Services Dear Mr, Prima: PAGE 0'-) Sarar,iuo-Kirby-Snow is pleased to present this proposal to assist the City of Lodi With a tectmical assessnvv of surface water supply options, From dis:cussions with City Staff, it is our understanding that there are four principal tasks, plus an optional rnodeliug effort.

Key to evaluation of these potential sources is deern)i� how the water could I)Q put to useA surface water supply could either be kept isolated frorn the existing Z:�N 'PAGE distribution sy-,sten'4 or the e istmi g system could be upgraded to accept a dual surface water/ groundwatu supply: Options that SKS MU evaluate that would not involve direct di.stri`bution to customers include groundwater hijection or pond recharge, direct supply for irrigation use, regional groundwater barktig projects (e.g. vv:th itiSJWCD), and bolding stonnwater in detention basins. The feasibility of developing n1face water treatment and delivery through the existing distribution system will also be evOtaated. ` bIS Task- vVali be initiated with a kick-off meeting pith trey City staff to facilitate' data transfer ar�d to bra.u- Istorm the range of possible surface water use options. For each opdotL SKS w€ develop an assessment of potential volume ofr se., a & riPtion of operations, a conceptual sizing of diversion xid distribution facilities, location rnapphg of these facilities, and a f a.sibihty-level cost estimate based on mit cost factors. We will also identifV key policy and regulatory considerations, such as treatment upgrades and compliance with the propos-ed Groundwater Rule.
