2020-07-09 City Council Meeting Agenda Item 05 - Cleath-Harris_202007021435151664

Council Agenda Report From: Dick McKinley, Public Works Director Subject: Award of Contract for Professional Services for Analysis and Design of Monitoring Wells and Stream Gauges for Supplemental Environmental Project Funding Date: July 9, 2020 Facts In January 2020, the City and three other Groundwater Sustainability Agencies (GSAs) jointly submitted a Groundwater Sustainability Plan (GSP) for the Paso Robles Basin The GSP calls for addition of groundwater monitoring wells within the basin to measure water levels in the Alluvial Aquifers, and in the Paso Robles Formation The State Water Board recently awarded a Supplemental Environmental Project (SEP) for analysis and installation of stream gauges and monitoring wells to the City of Paso Robles The requested work generally consists of analyzing and siting groundwater monitoring wells and stream gauges and requires the services of a hydrogeologist In April 2020, the City issued a request for written proposals from qualified hydrogeological consulting firms to complete the analysis, develop specifications and plans for installation of monitoring wells and stream gauges, and supervise their installation In May 2020, the City received two proposals for the requested work and completed a qualificationsbased selection Cleath-Harris Geologists, a hydrogeological consulting firm in San Luis Obispo, has proposed a scope of work and fee that meets the needs of the City and GSAs for this work and has been judged the more qualified and better fit for the requested work City staff has negotiated a scope of work, fee, and schedule with Cleath-Harris Geologists, which is attached The fee for this work is $111,524 Based on preliminary estimates of construction and installation costs, the available SEP funds ($255,000) are sufficient for the evaluation, design, and installation of two shallow monitoring wells and three stream gauges, and construction of two deep monitoring wells that will be bid according to the plans and specification prepared by Cleath-Harris Geologists Options Take no action; Enter into an agreement with Cleath-Harris Geologists for the requested analysis, design, and supporting technical work; or, Provide alternative direction to staff Analysis and Conclusions Cleath-Harris Geologists (CHG) has proposed a scope of work and fee that meets the needs of the City and GSAs for the requested analysis of monitoring well and stream gauge sites The scope of work includes the installation of two shallow monitoring wells and three stream gauges and the preparation of bid documents for construction of two deep monitoring wells Through their proposal CHG has demonstrated their qualifications, understanding of the project, and their experience with local hydrogeologic conditions and technical work required for the project Further, CHG has worked on several past projects for the City and has proposed a cost-effective scope of work that makes best use of available budget by increasing the number of wells that can be installed The schedule proposed by CHG meets the schedule required for utilization of the SEP funds and the fee proposed for this work is considered to be competitive and consistent with this type of technical work Agenda Item 05 Page No 072 CC Agenda 07-09-2020 Page of 30 Option 1: Taking no action would defer the selection of a hydrogeological consulting firm to complete the requested scope of work and, due to a short timeline required for utilization of SEP funding, would likely result in forfeiture of the available SEP funds Option 2: Authorizing the City Manager to enter into an agreement for the final design would allow Cleath-Harris Geologists to proceed with the analysis, preparation of specifications and plans needed for construction, and supporting work Option 3: Providing alternative direction to staff would allow staff to address any Council requests and return in time to preserve use of the SEP funding Fiscal Impact One-time cost for the proposed work is $111,524 Costs for installation of two deep monitoring wells (not included in the CHG proposal) are preliminarily estimated to total $59,180 The SEP funding available for the project is $255,000, which will cover all of the proposed work Recommendation (Option 2) Approve Resolution 20-XXX authorizing the City Manager to enter into an agreement for analysis, design, and preparation of bid documents for the SEP Groundwater Monitoring Well and Stream Gauge Project] with Cleath-Harris Geologists, in an amount of $111,524 Authorize the City Manager

Geologists, Inc 75 Zaca Lane, Suite 110 San Luis Obispo, CA 93401 (805) 543-1413 June 4, 2020 Christopher Alakel City of Paso Robles 1000 Spring Street Paso Robles, CA 93446 SUBJECT: SUPPLEMENT TO CHG PROPOSAL FOR SITING, DESIGN AND SUPERVISION OF MONITORING FACILITIES Dear Mr Alakel: Cleath-Harris Geologists (CHG) provided the City with a proposal for the Supplemental Environmental Project (SEP) monitoring facilities Since the submittal, the City staff has recommended CHG be selected for the work CHG presents this supplement as a result of further discussions with the City, with other Basin Management advisors, and with contractors for the equipment and construction This supplement includes an updated schedule (assuming completion by December 31, 2020), stream gauge equipment costs, and contactor costs for the shallow well drilling and construction The deep well drilling is assumed to require a formal bidding/contractor selection process and would be processed directly with the City of Paso Robles The scope and costs for CHG tasks as enumerated and described in our proposal are as stated The additional scope and costs to be incorporated into our services include the shallow well construction and the purchase of stream gauge equipment At this time, we expect that two 60foot deep 4-inch diameter monitoring wells will be constructed The stream gauge equipment is still not fully designed but our estimate in the proposal is in line with prices we have requested from manufacturers Installation costs for the stream gauges have been estimated but will need to be worked out with the County and the City or perhaps some of the other agencies in the Basin The incorporation of stream gauge equipment and shallow well constructions into the CHG contract should allow for quicker turn-around in arranging for mobilization and purchase SUPPLEMENTAL SCOPE OF WORK The additional scope items are as follows: Drill and install two 60-foot deep (“shallow”) monitoring wells Purchase and install three radar type stream gauges Paso SEP proposal supplement Agenda Item 05 Page No 076 6/4/2020 CC Agenda 07-09-2020 Page of 30 Exhibit A FEES AND CONDITIONS CHG proposes to provide the additional items in accordance with the attached terms of fees and conditions, shallow well drilling proposal and the stream gauge equipment at cost plus 10 percent The two shallow wells are quoted at $12,824.80 With 10 percent handling, the cost would be $14,110 (rounded) This cost could change, should site conditions vary The three bridge-mounted radar stream gauges are estimated to cost a total of $34,500 With 10 percent handling the cost would be $37,950 When combined with our proposed services costs ($59,464), the contract with CHG would total $111,524 Should additional services be required, the services would be billed at the hourly and expense rates presented below 2020 HOURLY RATE SCHEDULE Principal Hydrogeologist Senior Hydrogeologist Project Geologist Staff Geologist II Environmental Scientist GIS Specialist Staff Geologist I $160/hr $150/hr $135/hr $120/hr $120/hr $120/hr $105/hr EXPENSES Mileage $0.58/mile Other expenses at cost plus 10 percent handling DEEP WELL CONSTRUCTION (BY OTHERS) Deep well cost estimates were obtained from Filipponi and Thompson based on monitoring wells that they had installed in 2018 for a 190’ deep 5-inch PVC cased well and a 320’ deep 5-inch PVC cased well These wells were drilled and completed for a total of $53,800 The site conditions are not known and there will be a need for a deeper well seal (100’) Adding 10 percent on to their cost for these factors, the total contractor cost for two deep wells is estimated at $59,180 This work will be performed outside of CHG’s scope of work Paso SEP proposal supplement Agenda Item 05 Page No 077 6/4/2020 CC Agenda 07-09-2020 Page of 30 Exhibit A The total estimated cost of the project components including deep well installation is $170,704 This estimated cost is much less than what was estimated in the original proposal, as we have been able to clarify costs with contractors and equipment suppliers It will be wise to incorporate some flexibility into this cost proposal, should specific conditions be different than anticipated CHG expects to work with the City staff to establish the final stream gage designs and final number of shallow and deep wells for the project PROJECT SCHEDULE A project schedule is attached Work is scheduled to begin mid-June and be completed by the end of the year AGREEMENT If the herein described work scope, fees and conditions

Obispo County, California Exhibit A May 2020 Siting and design are factors in construction costs and scheduling For gauge installation within the stream channel, US Army Corps of Engineers and California Fish and Wildlife permitting may be required, which would take considerable time We can discuss these options and factors if given the opportunity to meet with the City for an interview WORK PROGRAM The work program is divided into two components: • shallow and deep monitoring well installations at two existing gauge locations • stream gauge siting studies with installation of one to three gauges at high priority locations Monitoring Wells The following work tasks are involved in establishing each of the proposed monitoring well locations Site Constraints/Technical Specifications • Visit the stream gauge locations to observe site conditions and constraints for shallow and deep monitoring wells • Obtain topographic and property survey information • Obtain and review historic stream channel variations on aerial photographs and existing plans for the bridge/stream crossings • Review groundwater/hydrogeologic conditions on which to base well design criteria • Perform geophysical survey to estimate the depth of the alluvium at the well site • Prepare a well site plan and technical specification for the monitoring wells • Consult with Nature Conservancy and California Fish and Wildlife for prioritization • Once approved, complete the bid package for advertising to contractors Well Drilling and Construction Monitoring • Prepare agenda for initial site meeting • Attend a pre-construction meeting • Coordinate mobilization • Log drilling cuttings/prepare a lithologic log • For the deep well only, interpret down-hole logging activities • Prepare final well design • Monitor well construction and air lift development activities • Install water level transducer • Pump each monitoring well to obtain water samples for general mineral/physical Agenda Item 05 Page No 087 CC Agenda 07-09-2020 Page 16 of 30 Exhibit A Supplemental Environmental Project Proposal Paso Robles Groundwater Basin – San Luis Obispo County, California May 2020 • constituents analysis using a sampling pump Prepare a final well construction technical memorandum Communications • Meet with City and Basin Management staff at the following project decision points: CHG project kick-off, completion of each dual monitoring well, and when the recommended stream gauge locations are selected Scheduled calls will be used to discuss project status and other milestones and deliverables • Attend meeting for presentation of project results Stream Gauge Siting/Design/Installation Supervision Between one and three stream gauges are planned to be installed out of the 10 gauges identified in the initial proposal The stream gauge portion of the project will consist of three steps: Prioritize based on significance of flow information for water resources management and agency consultation; Differentiate sites by type of gauge required, cost, access and installation constraints; and Implement gauge installation project though selection of gauge design, assisting the City in obtaining the gauge equipment, and supervising installation of the gauge(s) by others Prioritize • Review basin characterization studies and modeling of the surface water and groundwater recharge from streams • Identify which streams/rivers have the greatest potential for flow and recharge • Identify the streams/rivers that have the least well documented stream flow • Prepare a prioritized list of stream gauge locations Differentiate • The stream gauge sites will be differentiated into bridge mounted radar and bubbler types • Determine which bridge mounted radar sites are in strategic areas to gather data for recharge to, or discharge of, groundwater • Identify which sites have adjacent areas where groundwater monitoring wells could be installed or where existing wells may be available for monitoring • Select up to three locations where bridge mounted radar gauges can be installed Implement • Select gauge/telemetry data transmission system for locations • Identify vendors for the systems and obtain quotes for the City/Basin Management Agency/County Public Works staff • Supervise in concert with City Engineering/Basin Management Agency/County Public Works staff the installation of the systems Agenda Item 05 Page No 088 CC Agenda 07-09-2020 Page 17 of 30 Exhibit A Supplemental Environmental Project Proposal Paso Robles Groundwater Basin – San Luis Obispo County, California May 2020 PROJECT SCHEDULE The proposed work is planned to be performed during a relatively short time frame (approximately 10 months, based on RFP implementation schedule) CHG gets things done without sacrificing quality Personal communications with the City staff, contractors, and landowners will be critical to making sure everyone is informed about each step of the process CHG works with all of the local well drillers and can obtain quotes quickly and meet on site and remotely to discuss constraints and design factors Permitting agencies will be involved as soon as sites are selected Schedule Components For a monitoring well the schedule can be broken into several steps: • Well Site selection • Permitting • Well Design Specifications • Bidding/Contractor selection • Contracting for project • Construction For the stream gages, the schedule can be broken into four steps: • Gauge location prioritization • Selection of appropriate gauge design for each location (either bridge mounted radar or bubbler) and identification on the top three radar gauge sites • Purchase and install up to three radar gauges and data transmittal equipment • Test and activate gauge(s) Fast-tracking Monitoring Wells Some ways of fast-tracking the installation of monitoring wells could be in the area of contractor selection, type of well drilling, choice of sites, and site preparation A few alternatives are described below: Bringing a contractor under contract can be the most time-consuming part of the project If necessary and appropriate, CHG could include portions of the construction activities within its contract This is not currently a part of CHG services within this proposal Shallow monitoring wells can be fast-tracked with minimum site modifications and lower cost using hollow stem auger drilling methods Deeper wells would need be drilled using conventional mud rotary drilling equipment Agenda Item 05 Page No 089 CC Agenda 07-09-2020 Page 18 of 30 Supplemental Environmental Project Proposal Paso Robles Groundwater Basin – San Luis Obispo County, California Exhibit A May 2020 If a monitoring well site can be located on County/City property, the need to negotiate with the land owner for an easement could be avoided We are aware of some City-owned property that could be suitable for a monitoring well site location If an existing well on a private property is suitable for monitoring and can be used with an access agreement, it is possible an agreement could be accomplished quickly with direct discussions/negotiations We have observed some domestic and irrigation wells in the near proximity of the Airport Road stream gauge Permitting agency staff will be invited to the project sites early on to work through any site constraint issues, followed up with a memorandum documenting the issues and proper permitting procedures If required construction site modifications can be made by City/County, or even the property owner (if the site is on private property, with appropriate agreement), this would reduce the time that the contractor will need to be on-site We can further discuss fast track options if given the opportunity to meet with the City for an interview Fast-tracking Stream Gauges The stream gauges that can be most economically installed with the least permitting time will be the bridge mounted type It is assumed that to meet the implementation schedule, the bridge mounted telemetered radar gauge(s) with the highest priority would be installed BUDGET The Project Budget in the RFP includes planning/hydrogeologic/engineering services and equipment and facilities purchase/installation The planning and engineering would be performed by the City/Basin Management Agency The installation/construction of facilities would be performed by a licensed contractor Cleath-Harris Geologists would provide hydrogeologic/water resources analytical and supervisorial services We estimated the telemetered radar gauge equipment to cost $7,500 each in 2013 (Toro CreekChevron), and the current costs are estimated at $9,000 Installation and testing costs (by others) are estimated at $2,500 per gauge Three gauges would cost an estimated $34,500 A hollow stem auger constructed 4-inch diameter monitoring well drilled to 70 feet is estimated to cost $14,000 A 200-foot deep 5-inch diameter monitoring well is estimated to cost $50,000 A 300-foot deep 5-inch diameter monitoring well is estimated to cost $60,000 We figure that the 13th Street monitoring wells should be 70’ and 200’ deep, for a cost of $64,000 The Airport Agenda Item 05 Page No 090 CC Agenda 07-09-2020 Page 19 of 30 Exhibit A Supplemental Environmental Project Proposal Paso Robles Groundwater Basin – San Luis Obispo County, California May 2020 Road monitoring wells would include a 70’ and 300’ deep well, for a cost of $74,000 The total construction/equipping cost of the two sites with monitoring wells at each site is estimated to be $138,000 Of course, if there are existing wells nearby that could be used, the costs would be based on the easement/access agreement Cleath-Harris Geologists will provide services based on our hourly rate schedule below We estimate that the cost of the monitoring well hydrogeologic services would be $16,000 per site and the cost of the stream gauge analysis and supervision would be $27,000 Assuming two monitoring well sites, the estimated total cost would be $59,000 Combining all of the costs for three stream gauges and two dual monitoring well completions, with CHG services, the total cost of the project would be $231,964 The cost of the public agency services is not included herein Manpower allocated to the tasks are summarized below: Tim Cleath
