Bloomquist Vice President, CH2M HILL, Inc. ATTEST: o z City �er , G,.--p of ds Date: July 2, 1996 2 Task Order 12 Redlands Water Resources Management plan Bunker Hill Groundwater Basin Technical Support Attachment A Scope of Work Purpose The City of Redlands currently receives a Significant amount of its water supply m t 7roundwater Basin. The basin is adjudicated but a number of agencies have Burxker Hill C from he been evaluating the operation and use of the basin. Some aspects of basin operation are evaluated by the Western Watermaster, San Bernardino Valley MWD is evaluating basin use in regional water resources, the RWQCB is studying T N. /TDS issues, and the San Bernardino Valley Water Conservation District operates spreading basins- In 1994 the SAW'S approved establishing Project Agreement 17, "Bunker HUI Groundwater Basin Cooperative Studies and Projects'to identify and evaluate rising groundwater issues, contaminant plumes, and conjunctive use activities in the basin, assess and understand how those activities are interrelated, and coordinate with local agencies to develop alternative plans to integrate those activities. The SAW-PA study was deferred until completion of the SBV4M%TDt p for Regional Water Facilities. That being complete, SAWPA recently co sl MU ter ]an 6(basins a scope of work for evaluating use of the basin and downstrearn of the dike) and develop or Projects 17 and I and the staff of member agencies to combines studies f mmis oned'its staff Potential export of water to agencies outside the basin. The purpose of this task order is to add Redlands groundwater data and well operations data to a database compatible A-th the GIS database developed under Previous task orders, to monitor activities by SA IPA agencies, monitor and comment on SBVW"CD activities that could impact Redlands, review soon to be completed USES groundwater model of the basin, and to attend other memrtgs regarding the basin as directed by the City. Scope Task 1. Maintain City Groundwater Data nder previous task orders C112M HILL initiated use of an AaCIWO GIS database to store, analyze, and display surface water resources data for the W-FW, Recently, SBD provided the City and CH2M!ML digital data for general groundwater basin boonesand specific well location infOl-mation. The goal of t.is task is to iricorporate the City of Redlands well data(e-g., water level data, water production, water quality) into the GIS database to ser-,re as a basis for potential future evaluations of City well OPerations, proposed City etc. SB operations, conjunctive use proposals by SB XM-D, 0 TO/f 0o[Z 03S 111H KZK) 0967 R7f fT/ TV- -Y A I IT " -1 - vi Annual water quality data for indivdual City wells is maintained in a Lotus 1-2-3 spreadsheet by the City, while More frequent sampling results are in hardcopy format, The City curre, keeps records of depth to water for wells in a PC-based database referred to e well eptly Depth,V as th e gement System( 'DMS) The City also keeps records of monthly production in a similar database(approy�imatejy 1995 to the present; older production data are in historically, the Primary purpose for trackin format). H hardcopy quality data is for reporting reo S Production, water level, and water ,uirements (e.g., to the Department of Health Services, Department Of Water Resources, or the WLerma ster), A secondary purpose is to track . to water in wells to evaluate the need for artificialrecharge in the Blinker Hill groundwaterdep& basin. Production well water quality, water,level, and production data will eventually be merged with the City's GIS. The 'DMSand production well database currently have limited capabilities (e g., data plots cannot be generated without exporting water level data to another software package such as Lotus 1-2-3) and are not compatible with a GIS. Since the City its developing a GIS and will want access to historic and future production well data with the GIS, using one comprehensive software package for all production, water level, and water quality data maintenance is cost-cffective. To accomplish this. CH 22 L will apply a commercially available software package: AccessZ, Ecrosoft Corporation- Access can act as the graphical user interface with GIS for inputting data, creating data plots, and reporting figures NFO GIS can be used primarily for presenting spatial data provided I and 2), while the ARCA 'F from the Access data base (see Figure 3 for exampley Subtask L Obtain Well Data CH12M HILL will obtain well data from the City in both hardcopy and elemonic-format, CH2M FM_L wit] prepare a check 'list of data for each well for inclusion in the database based on discussions with the City. These data may include the following well information/construction data, well name, state well number, recordation number,x, y, and z coordinates for the well (i-e_ location and elevation), well depth, screen intervals, well status, and casing diameter- Additional data for inclusion in the City's GIS may include depth to water(pumping or static water level) and date, amount of groundwater extracted and date (e,g., acre-feet per month), and water quality data and date, These data will cover the time period of 1960 to 1996. "We assume that the City will provide photocopies and diskettes to us. This will require at 1 One visit to City offices- Subtask 2. Enter Data into _31nCrosoft Access Database CH2M HILL data enttrystaf, will enter the data collected in Subtask I into NE-crosoft Access& All entered data will undergo a 10 percent quality control check versus hardcopy information. Any discrepancies be corrected and an additional percent of the data will be checked and corr.ected, if necessaj_y. Data will be entered from hardeopies and will also be transferred in el alio form.at from the City's spreadsheets and databases. CH21 HILL will develop and create the Access e_ database structure in con&WItation with City and ESRJ staff working on the Water, Facilities Diaster plan.

Bloomquist, r/1 Vice President, CH2M HILL, Inc ATTEST: Beat:roe --Sanczuty City Clerk,City ofditds 2 Task Order 8 Amendment No. I Redlands Water Resources Management Plan Upper Santa Ana River Water Resources Studies Attachment A Scope of Work Purpose The purpose of this amendment to Task Order No, 8 is to allow continued engineering consulting support to City of Redlands (City) staff on water resources and supply quantity issues on the Santa Ana River. Initial efforts under Task Order No 8 identified a number of issues to be addressed and new information regarding historical flows and diversions have been made available for estimating historical flows and diversions. CH2M HILL will work with City staff and others to identify historical flows and water use and assess impacts of projects by others on City water supplies Scope of Additional Efforts by Task Task 1. Surface Water Hydrology/Historical Diversions Coordinate efforts with consultants for other local agencies to obtain long-term hydrologic records for the Santa Ana River(1911 - 1993) and the Redlands Tunnel. Access hard-copy records from BVTMWC and translate into digital format for the period 1962 - 1992 to coordinate with a"base period" of Santa Ana River hydrology that is being proposed by consultants for SB'vlvfWD and EVWD. As recommended in previous work under Task Order No. 8: Review actual system operation and flow measurement by BV.MWC and SBVWCD. Review and document flow measurement devices at key locations in the system downstream of SAR 3 to determine their existence and accuracy. Each site will be visited, photographed, and documented as to the type of flow measurement device. Revise statistical analyses of stream flows and diversions and relate diversions to stream flow. Task2. Groundwater Hydrology Based on CH2M HLLL's initial work on Task Order No. 8 three new subtasks were recommended. The recommended subtasks are included in this amendment: • Obtain and review the dewatering data for construction of the Seven Oaks Dam. Compare the surface flow measurements at USGS Gage 110515.00 to the dewatering flow to estimate the percentage of underflow that comprised the diverted flow. This analysis should provide one check on the USCOE estimate of 3 cfs for river underflow. • Obtain and review the actual bedrock cross section at the dam. Recalculate the original USCOE estimate of underflow using the new and more accurate cross sectional data. This analysis will provide a second check on the USCOE estimate of 3 cfs for river underflow. • Review the upcoming USCOE feasibility study regarding release from the Seven Oaks Dam. The analyses should compare natural flows, flows with flood control operation, and flows with flood control/water conservation operation. Since it is likely that the tunnel outflow is affected by surface flow as well as underflow, the duration of surface flow could be significant. Under flood control operation, the duration of release from the dam could be extended, which may increase the yield from the tunnel. However, under a water conservation operation, this benefit could be negated. Task 3. Water Budget Revise the water budget from stream flow and groundwater use based on new data from the consultant team to demonstrate historical beneficial water use by water rights holders of importance to the City. Develop a schematic of the Santa Ana River water systems highlighting key locations for City water supplies. Task 4. Legal/Institutional Relationships Update the flow chart of legal and institutional relationships that allow Santa Ana River water to serve the City and other local service areas of importance to City water supplies. Develop preliminary flow chart for review by City and others. Meet with City staff and others to re-vise and correct flow chart Task 5. Assessment of Impacts Review the US Corps of Engineers water supply study for Seven Oaks Dam and provided memorandum to the City with comments. Task 6. Meetings/General Support The intent of this task is to allow the CH21M HILL Project Manager, Michael Savage up to 80 hours to attend meetings not scoped in Tasks I through 5 with City staff, other water agencies, regulatory agencies, SCE, etc. as directed by the City, Products The product of Tasks I through 5 will be a revised technical memorandum consisting of brief text summarizing the tabular and graphical displays of historical surface stream flows and water diversions, specific comments on Corps of Engineers analysis of river underflow at Seven Oaks Dam, flow charts of legal/institutional relationships, and a summary of potential water supply impacts.
