This proposal and opinions of probable costs are based on our current understanding of the project. Colorado Civil Group (CCG) with act as the Town representative and project manager. ME will lead the project and design the horizontal well. MWE will subcontract, W • Groundwater modeling and general engineering support to Miller Groundwater Engineering, LLC (MGE); • The vault, pump station and pipeline design to Acuity, Inc. (Acuity); and • Geotechnical engineering to Cesare, Inc. Assuming contracting will occur in January 2019, we anticipate the project lasting approximately 13 months and being completed by March 2021. Appendix A includes a Gantt chart that shows live project phases, anticipated date ranges and how tasks will likely overlap. Figure 1 shows the existing site, preliminary horizontal well alignment and necessary infrastructure including: • A 500 ft long H-well and 500 ft long recharge trench; • An improved head gate diversion to a single 500 ft long recharge trench; • A wet -well (vault) with two vertical turbine pumps; • A simple wood -framed type pump house with power, valves, flow meter, and controls; • Approximately 600 ft of pipeline to the future water treatment plant site boundary; and • Approximately four additional monitoring wells around the site. MWE Horizontal Well, Pump, Pump House and Pipeline Proposal December 16, 2019 Page 2 of 11 In addition, several geotechnical boreholes will be drilled along the horizontal well alignment. Figure 1—Horizontal Well Site an For water discharges during construction dewatering and H-well testing, we propose installing a temporary, plastic -lined trench to a new 30400t long 124n culvert located under the Varra property entrance and allow the water to recharge on the east side of Colorado Blvd. A permanent drainage system will be installed during a later phase of the project. According to Dave Lindsay (CCG), the immediate goal is to install an H-well that will provide the Town's planned water treatment plant (WTP) with 220 gallons per minute (gpm) on a year-round basis and provide a peak summer (June -August) rate of 520 gpm. In the future, when demand increases, the year-round production rate goal will be approximately 350 gpm with a peak summer rate of approximately 1,050 gpm. The design will also consider minimizing impacts to the Pelican Shores Subdivision and Lake located on the west side of Colorado Blvd, as discussed below. It may be necessary sometime in the future to add additional recharge trenches, or add an additional H-well to the south, depending on actual year-round operations, H-well performance and future demands. Computer modeling is a critical component in the system's design, in the interpretation of the start- up test, and for planning future operations. The modeling will rely heavily on water level data documented at the site's existing and future monitoring wells. For example, prior groundwater modeling of the facility indicates that groundwater currently flows through Pelican Shores Lake at a substantial rate and that the H-well operations will increase that rate of groundwater flow through the McGrane Water Engineering, LLC 1669 Apple Valley Rd. •Lyons, CO 80540 •Phone: (303) 917-1247 1; Mail: Bennis a mc�,n•auc«ater,com Wcb:[q>://www.nugranewatcrengiuccring.com MWE Horizontal Well, Pump, Pump House and Pipeline Proposal December 16, 2019 Page 3 of 11 lake. Ongoing data collection and modeling will be used to monitor and manage that effect. Similarly, Managed Aquifer Recharge (MAR) will be used to refill the aquifer beneath the site, which will also cause groundwater levels to rise around the east side of the lake and beneath the subdivision. Therefore, future site operations will need to include active monitoring and modeling (especially for the first few years) to guide management decisions such as recharge timing and recharge amounts. The suitability of an H-well at the Gould site was initially described in MWE's and MGE's joint Phase II Groundwater Supply Study (MWE, June 2018). We concluded that a 1,000-ft-long horizontal well located there could sustain at least 180 gpm year-round without MAR and over 1,000 gpm when MAR is available. To gain additional confidence in this prediction, we performed two large-scale pumping and recharge tests in the summer and fall of 2018. We installed additional monitoring wells and two 30M long recharge trenches in existing agricultural ditches at the Gould site, and then conducted a 60-day pumping test and 10-day recharge test. We used a computer model of those tests to further evaluate aquifer conditions, project sustainable yields, and evaluate the relationships between recharge and various vertical and H-well wellfield configurations. We concluded that two 500-ft long horizontal wells located on the Gould property could produce approximately 220 gpm year-round and up to approximately 280 gpm during the summer months (Scenario D). If two 550-ft recharge trenches were installed and MAR were available between June and September, then the 3-month peak summer yield projection increased to approximately 1,000 gpm (See Table 2 of MWE draft memo to Dave Lindsay, December 9, 2018). The scope of this initial phase of the project is to install a single 500-ft horizontal well and extend one of the existing recharge trenches to 500 ft. Based on ongoing modeling by MGE, we estimate that a single 500-ft long H-well can likely achieve the short-term goal of providing 220 gpm year-round without recharge, and with recharge can achieve the peak summer goal of 520 gpm. Engineering tasks for each phase are listed below with a basic explanation. Deliverables are marked with an asterisk (*). Below each subtask, we provide an opinion of probable cost for the primary construction activities. These cost opinions are also included in the Table 2 cost summary.

(Craig Vaughn) to discuss geotechnical support; • Met with a horizontal drilling contractor and obtained a well cost estimate, • Corresponded numerous times with MGE and CCG concerning H-well design (gravel pack, materials, length, diameter); • Prepared a preliminary proposal outline* for CCG to review in May 2019; • Met with MGE and CCG again on October 11, 2019, to discuss project details; • Prepared draft proposals* dated November 8, and December 2, 2019; • Met with the Town (CCG), Acuity and MGE on November 1 Vh ; • Conducted a conference call on December 13, 2019; and • Prepared this final proposal*. Horizontal wells are unique. To our knowledge, there are less than five horizontal municipal water supply wells in Colorado. We have already conducted basic research into different types of horizontal wells and installation approaches. In the MWE memo to Dave Lindsey (Colorado Civil Group, Inc.) dated December 9, 2018, we concluded that a horizontal well installed by trenching will likely "provide the greatest reliability and operational flexibility" for the Town. In the same memo, we discussed how we developed and calibrated a groundwater model that we believe accurately predicts H-well production with and without MAR. Today, we still conclude that a horizontal well installed by open trenching (rather than directional drilling) will provide the greatest reliable yield for the town, but due to the aforementioned uniqueness of such wells, and in particular the unique situation of installing that well by open trenching, there are numerous design and logistical construction considerations to be evaluated. Numerous details still to be evaluated, in part by modeling, include; (i) well construction materials such as wrapped -screen stainless steel vs, perforated PVC pipe, both of which have a range of open areas; (ii) whether using two smaller diameter perforated well pipes is better than using one larger well pipe; (iii) trench location relative to Pelican Shores; and (iv) ongoing consideration of MAR scheduling and recharge rates along with monthly extraction scenarios. Geoteehnical drilling and testing also needs to be done early in the design phase. Geotechnical drilling (sites not yet determined) and laboratory tests are important to developing a safe excavation program and evaluate foundation design options. Figure 1 shows the four proposed additional monitoring wells located around the site perimeter plus another one near Pelican Shores' homes to monitor sub -basement groundwater levels. 1VIcGrane Water Engineering, LI.0 1669 Apple Valley Rd. •Lyons, CO 80540 •Phone: (303) 917-1247 &Mail: Bennis �� mein auewatcr,1 0com AWE Horizontal Well, Pump, Pump House and Pipeline Proposal Page 5 of 11 December 16, 2019 Therefore, under Task 2 of this project, we propose the following pre -design tasks: • Task 2.1 —Researching and evaluating: horizontal well design options such as screen materials and open area, plus construction/trenching techniques and wet well options (precast and cast in place). • Task 2.2 - Computer modeling various: screen materials and designs; horizontal well locations; recharge trench locations, depths and widths; delivery periods and rates; and potential impacts to Pelican Shores. We will prepare a memo* to the Town describing our "preferred design" recommendations. • Task 2.3 —Researching and computer modeling of dewatering options (prior to and during construction) and documenting our conclusion summary in an internal memorandum*; and • Task 2.4 — Geotechnical drilling, sampling and testing, and monitoring well installation at approximately 3 to 5 locations. In addition, a preconstruction site survey is necessary to prepare a site plan and identify existing utilities and easements. Cont��actor Cost Estimates: $50,000 for geotechnical engineering, drilling, laboratory analysis, monitoring well installation and a site survey which will be subcontracted through MWE. We will design and prepare a single contractor bid package for six critical project components. �iaal Hoa�azzontal Tell azad 7'es I�esi,� The design of both horizontal well segments (current segment and potential future expansion) and wet -well vault must comply with the Colorado Water Well Construction rules and meet the design review requirements of the Colorado Department of Health and Environment (CDPHE). We will prepare preliminary designs prior to finalizing the bid documents and meet with regulators to get them involved with this iterative process. We will conduct extensive tests with a temporary pump after the H-well is installed. For budgeting purposes, we anticipate testing will include: 1) conducting a 5-day pumping test at 150 to 300 gpm to determine the minimum sustainable pumping rate; and 2) conducting a 5-day recharge pumping test at pumping rates up to 1,200 gpm to determine maximum sustainable recharge and pumping rates. This plan may be revised based on additional computer modeling or based on the partially dewatered condition of the aquifer at the end of well construction. MGE will interpret the pumping test with the computer model. The test results will be used to finalize the permanent pump design. Dewate' Although each bidder will be asked to provide a dewatering plan with their bid, we plan to also use our site groundwater model to evaluate the feasibility of their proposals.

MGE will conduct the modeling, document our results in a task memorandum* and use the results to evaluate the dewatering proposals provided by contractors. Acuity will evaluate the structural and hydraulic benefits of both precast or a cast -in -place design options and decide which is(are) acceptable. The design must also meet CDWR and CDPHE construction requirements discussed above. For budgeting purposes, we have assumed the "highest cost" option that involves installing a 10 foot square cast -in -place vault as the wet -well that could cost approximately $250,000. Piunp House The pump house will be a basic wood -framed design on a foundational slab with footings. The building will be insulated and heated. The piping will likely be sized for two pumps, each capable of providing 200 to 550 gpm (maximum 20 horsepower). Elechic Service We anticipate using 480v three-phase power. We will coordinate power to the site by contacting United Power and providing load demands for the pump and pump house. The cost will vary depending on whether power comes from south of the site (on CR 26), or from an existing transformer located across Colorado Blvd near the proposed well house. It will likely take 3 to 4 months for United Power to review our design and bring power to the site. �'umpmg System and Controls Our contractor cost estimate below is based on assuming two 20-horsepower vertical turbine pumps one primary and one back-up) installed in the well house above the wet -well vault with Variable Speed Drives (VFD). MWE and Acuity will work together to size and design the system prior to construction, but may revise the final pump design after testing is complete. At the request of CCG, we are not including System Control and Data Acquisition (SCADA) components in our scope of work. We request that the Town provide us necessary considerations for SCADA to be installed at a later date, which may include oversized control panels or specialized water level transducers or electronic flow meters.

The total cost for engineering and construction is $1,752,000. Due to the high uncertainty in construction costs, we added a 40% contingency totaling $502,000. The greatest component of uncertainty is the H-well installation which could take 60 to 90 days depending on the dewatering and trenching methods and effectiveness. Therefore, we recommend that the Town budget $2,254,000 for the project. This is $154,000 more than our preliminary cost estimate provided last year, but the earlier estimate did not include the water pipeline to the water treatment plant (MWE, 12-94 8). Our current proposal also does not include: drainage improvements, permanent access roads or security fencing, existing trench restoration or SCADA equipment for remote operation or data collection. Payments for our services, like other professional services, are based on the actual time spent on your behalf and at hourly rates offered for this specific project scope ($168/hr for Dennis McGrane (MWE), $193/hr for Kevin O'Connell (Acuity) and $145/hr for Calvin Miller (MGE). Billing occurs on a monthly basis and payment is expected within 30 days. We request the Town: • Subcontract separately with contractors shown on Table l . • Arrange permission with the Pelican Shores HOA to drill one additional permanent monitoring well on their property (Figure 1) which we will equip with a water level sensor to monitor water levels during testing. At a later date, the Town may decide to install a continuous data logger with SCADA to provide continuous, real-time monitoring of water levels at that location, or similar, near the Pelican Shores basements. • Request permission from the Pelican Shores HOA to discharge some of our construction dewatering water to their lake due to the fact that that our construction dewatering pumping will be much more intense than future water -supply operations. We would like to pursue two dewatering discharge options: (1) route water to the river directly north along CR 13 right of way or possibly along the existing tail water path to the east (used during the Fall 2018 recharge test), and (2) to Pelican Shore Lake through a pipe routed under CR13 via an existing irrigation culvert. Having both options may be necessary to mitigate real and perceived impacts with the HOA. We believe the State would likely grant us dewatering discharge permits for both. To accomplish this, we ask the Town to request permission from the HOA to discharge our water to their lake. • Acquire the necessary water rights for the project and arrange for surface water deliveries in September and October, 2020 for H-well and MAR testing. • Obtain permission to install temporary discharge piping to allow dewatering discharge to recharge between the Varra property and Colorado Blvd, McGrane Water Engineering, LLC 1669 Apple Valley Rd. •Lyons, CO 80540 •Phone: (303) 917-1247 l;-Mail: Bennis«mcgrane��aLer.coin Wcb; ttp://������:mcgranc«-atercn�incering.com MWE Horizontal Well, Pump, Pump House and Pipeline Proposal December 16, 2019 Page 10 of 11 T ime Required We envision the project can be completed in 13 months by March 2021, Appendix A includes a Gantt chart that shows how some tasks overlap. Delays caused by circumstances beyond the control of the engineer could extend the time of completion. Risk It should be understood that the well type and installation method we have selected for this well is arguably unique for high -capacity water wells and contains several site -specific considerations. If a more common type and more routine installatimi method had been the highest priority, then we might have given more consideration to selecting multiple vertical wells, or large diameter vertical wells, or alternative H-well installation methods. However, at the Town's direction, the highest priority for this well has been clear: provide the best reliable yield possible given the hydrogeologic limitations of the site. That directive includes providing the desired yield at times with lower aquifer water levels, such as what might occur many months between potentially seasonal recharge operations. In response, we did consider several other options, but concluded that a horizontal well, installed via open trenching, is the preferred approach for the site conditions. There is also risk when constructing any type of well, since there is uncertainty and variability in aquifer properties away from where test drilling occurred, plus uncertainties associated with groundwater modeling projections. Actual performance maybe different from expected and projected performance, Finally, our consulting services have been limited to assessing site hydrogeologic conditions and projecting sustainable yield of a wellfield at the site. We have not been closely involved with all associated decisions such as characterizing the water quality or evaluating the cost -benefits of other water supply options. Contracting We envision the Town will include this proposal as an attachment in their standard professional services contract and MWE will subcontract work to other consultants as needed. We look forward to working the Town of Firestone and CCG on this project. Sincerely, MCGRANE WATER ENGINEERING, LLC. Dennis McGrane, P.E., C.P.G.
