ENGINEERING CONSULTANTS April 29, 1996 Mr. Eric McCafferty Garfield County Planning and Zoning Commission 109 Eighth Street Glenwood Springs, CO 81601 Re: Levitt Subdivision Missouri Heights Dear Eric: (970) 945-5700 (970) 945-1253 Fax To supplement our April 1, 1996 pump test letter report, we have collected additional data that is relevant to the Levitt Trust Well #2, tested on March 20, 1996. In our April 1, 1996 letter there was concern over the rate at which the aquifer recovered and whether the pump test resulted in a permanent lowering of the local aquifer. Additional data was obtained by Samuelson Pump Company on March 26, 1996 that showed the water level in the Levitt Trust well #2 was at 254' 7". This level is 4" above the water level measured on March 21, 1996 during the recovery portion of the original test. This would indicate the water level was not permanently reduced by the 24 hour pumping test. We believe this early spring testing period would be the lowest aquifer level of the season and should represent for conservative aquifer estimates. Table 1 (attached) further refines the proposed water uses in the Levitt Subdivision. The total number of proposed units has been reduced to 23 units. 13 single family units - Levitt Subdivision 2 guest houses - Levitt Subdivision 8 single family units - Reserved by Levitt Family Trust 23 total units upon which property the wells and storage tank are located It was assumed that each of these units will have 1500 ft2of outside irrigation. It is also assumed that there will be no more than 12 livestock units on the property. Table 1 shows that on the average the proposed homes will divert 12.70 acre feet (7.9 gpm) per year. The peak diversion month will occur in June when 1.61 acre feet (12.12 gpm) will be diverted. We have estimated that 3.98 acre feet (2.47 gpm) will be consumed by the subdivision on an annual average. The well was pump tested at a rate of 20 gpm with a total draw down of approximately 1.8 feet. During the same period when the well was tested, the water system requirements would be approximately 6 gpm or 30% of the tested rate. It is our opinion that there is a substantial reservoir that can be drawn upon by the proposed Levitt Subdivision. As with any water resource, the supply is dependent upon seasonal recharge. Just as a municipality goes to the field and observes the reservoir level to evaluate their water supply, a prudent homeowners association should measure their water level in their aquifer to evaluate their available supply. We believe that this well is capable of supplying the subdivision needs. We recommended that a backup well be constructed at 50% of build out to provide additional system reliability. At your request we have also provided a revised Figure 2 from our original report showing 254' 11" static water level, measured March 19, 1996.

Box 414740 Kansas City, Mo. 64141 Re: Levitt Trust Well #2 Dear Tom: (970) 945-5700 (970) 945-1253 Fax At your request, Zancanella and Associates, Inc. has conducted groundwater investigations to determine the resources available for your proposed Missouri Heights subdivision. A recent pump test has been completed for the Levitt Trust Well #2 to determine the well yield. The well is currently registered as a monitoring hole with Division of Water Resources under permit No. MH -27420 and is located in the NE 1 /4 of the SW 1 /4 of Section 28, Township 7 South, Range 87 West of the 6th P.M. 2001 feet from the West section line and 1470 feet from the South section line. The approximate location of the well is shown on the attached site map (Figure 1). The Levitt Trust Well #2 was drilled to a depth of 320 feet and constructed with a 5.5 -inch diameter casing. The water bearing portion of the well is in a sandstone member of the Eagle Valley Formation. The attached Figure 2 has been prepared to illustrate the well construction details. The static water level in the well on March 19, 1996 was 254.92 feet below the top of the well casing. The available drawdown in the Levitt Trust Well #2 is approximately 65 feet ( 320 ft - 255 ft). The well was tested on March 19, 1996 by Samuelson Pump Company. A two - horsepower pump powered by an electric generator was installed for the test. A pumping rate of 20 gallons per minute (gpm) was selected and the well was pumped continuously for a 24-hour period. Drawdown and time data collected during the test is presented in the attached Table 1. The drawdown data can be used to determine the yield of a well and associated aquifer. The drawdown is the distance the water level drops from the initial static water level and can vary over time dependent on the pumping intensity. We have plotted the pump test data in a drawdown vs. time curve for Well #2 as shown on the attached Figure 3. The well drawdown was approximately 1 -foot over the first hour of the test and further dropped to 1.9 feet at the end of the 24-hour test. The well showed continuous drawdown with time and did not stabilize. The pumping level at 20 gpm stayed well above the pump intake during the pumping test.

Based on the available drawdown the well should be able to pump continuously in excess of 100 days at the test rate of 20 gpm. Recovery data for the well was collected for a 24-hour period after pumping had stopped. The recovery data is also presented in Table 1. The recovery plotted as residual drawdown is shown in Figure 5. Based on the residual drawdown curve, the well did not display positive recharge characteristics, or in other words the well did not recover at a greater rate than it was pumped. The well did not return to the original static water level which would indicate that water pumped during the test was from storage in the underlying aquifer and the current recharge rate of the aquifer is less than the pump test flow. Annual water volumes pumped from the aquifer will need to be matched or remain less than the annual recharge to the aquifer system. The attached Table 2 presents the estimated water diversion requirements for the proposed 13 residential unit development. We have assumed that each residential unit will have 3.5 people, each using 100 gallons per person per day. We understand that some of the residential units will include guest houses. For purposes of this analysis we have conservatively assumed an additional 3.5 persons for each unit to account for any guest facilities. The irrigated lawn and garden area for each unit was estimated to be 3000 ft2 (1500 ft2 residential + 1500 ft2 guest house) for a total area of 0.9 acres. An additional 0.5 acres of irrigation demand was included to cover any greenbelt or park space within the proposed development. The irrigation consumption requirement was estimated to be 1.87 acre-feet/acre and is distributed over the growing season based on plant demands. The irrigation application efficiency was assumed to be 70% resulting in a diversion requirement of 2.67 acre-feet/acre (1.87/.7). An additional demand for 12 livestock was included at a consumption rate of 15 gallons/unit/day. Based on the above assumptions, the peak diversion month would occur in June with a demand of 1 .78 acre-feet or 13.4 gallons per minute and the average monthly demand would be 1.18 acre-feet/month or 8.9 gpm. The annual diversion requirement is 14.16 acre-feet. The estimated annual water consumption requirement is 4.35 acre-feet, with 1.53 acre-feet attributable to "in house" uses and 2.81 acre-feet from irrigation and livestock needs. The entire 13 units will require a larger instantaneous peak demand than can be provided for by the well alone. On site storage will be provided to supply peak domestic and fire storage demands. Sizing of storage facilities and associated distribution pipelines will be provided by High Country Engineers. It is our opinion that with proper storage the well will be capable of serving the development's domestic and irrigation needs assuming the aquifer characteristics provide adequate recharge capabilities. We recommend that the aquifer be monitored on a regular basis so that the water resource can be properly managed. During periods of low recharge (like a 1977 dry year), irrigation from the well at the proposed development might require curtailment if seasonal recharge volumes are low. We recommend that a second well be constructed to provide mechanical reliability to the system. The second well should be constructed at approximately 50% of build out of the subdivision. The Levitt Well #1 (Monitoring Hole No. 27419) has been constructed but has not been tested and may be suitable for this purpose.

The legal water supply can be provided from contract water with the Basalt Water Conservancy District. The contract water enables use of district water rights to replace or "augment" diversions from the development, thus protecting any downstream water rights. Diversions from either well would initially be covered under a temporary exchange plan currently approved by the Division of Water Resources. Use of the contract water will eventually require formal approval under a court approved augmentation plan at which time only the consumptive portion of water use will have to be replaced. Well permits from the Division of Water Resources will be approved subject to being covered by the Basalt Water Conservancy District temporary exchange plan. Finally, water samples of the pumping discharge were taken from Levitt Trust Well #2 but have not yet been analyzed by the investigating laboratory. We will make the results available to you as soon as we receive them from the lab. We estimate the laboratory results will be available on April 3rd or 4th 1996.

Box 414740 Kansas City, Mo. 64141 Re: Levitt Trust Well #2 Dear Tom: (970) 945-5700 (970) 945-1253 Fax At your request, Zancanella and Associates, Inc. has conducted groundwater investigations to determine the resources available for your proposed Missouri Heights subdivision. A recent pump test has been completed for the Levitt Trust Well #2 to determine the well yield. The well is currently registered as a monitoring hole with Division of Water Resources under permit No. MH -27420 and is located in the NE 1 /4 of the SW 1 /4 of Section 28, Township 7 South, Range 87 West of the 6th P.M. 2001 feet from the West section line and 1470 feet from the South section line. The approximate location of the well is shown on the attached site map (Figure 1). The Levitt Trust Well #2 was drilled to a depth of 320 feet and constructed with a 5.5 -inch diameter casing. The water bearing portion of the well is in a sandstone member of the Eagle Valley Formation. The attached Figure 2 has been prepared to illustrate the well construction details. The static water level in the well on March 19, 1996 was 254.92 feet below the top of the well casing. The available drawdown in the Levitt Trust Well #2 is approximately 65 feet ( 320 ft - 255 ft). The well was tested on March 19, 1996 by Samuelson Pump Company. A two - horsepower pump powered by an electric generator was installed for the test. A pumping rate of 20 gallons per minute (gpm) was selected and the well was pumped continuously for a 24-hour period. Drawdown and time data collected during the test is presented in the attached Table 1. The drawdown data can be used to determine the yield of a well and associated aquifer. The drawdown is the distance the water level drops from the initial static water level and can vary over time dependent on the pumping intensity. We have plotted the pump test data in a drawdown vs. time curve for Well #2 as shown on the attached Figure 3. The well drawdown was approximately 1 -foot over the first hour of the test and further dropped to 1.9 feet at the end of the 24-hour test. The well showed continuous drawdown with time and did not stabilize. The pumping level at 20 gpm stayed well above the pump intake during the pumping test.

Based on the available drawdown the well should be able to pump continuously in excess of 100 days at the test rate of 20 gpm. Recovery data for the well was collected for a 24-hour period after pumping had stopped. The recovery data is also presented in Table 1. The recovery plotted as residual drawdown is shown in Figure 5. Based on the residual drawdown curve, the well did not display positive recharge characteristics, or in other words the well did not recover at a greater rate than it was pumped. The well did not return to the original static water level which would indicate that water pumped during the test was from storage in the underlying aquifer and the current recharge rate of the aquifer is less than the pump test flow. Annual water volumes pumped from the aquifer will need to be matched or remain less than the annual recharge to the aquifer system. The attached Table 2 presents the estimated water diversion requirements for the proposed 13 residential unit development. We have assumed that each residential unit will have 3.5 people, each using 100 gallons per person per day. We understand that some of the residential units will include guest houses. For purposes of this analysis we have conservatively assumed an additional 3.5 persons for each unit to account for any guest facilities. The irrigated lawn and garden area for each unit was estimated to be 3000 ft2 (1500 ft2 residential + 1500 ft2 guest house) for a total area of 0.9 acres. An additional 0.5 acres of irrigation demand was included to cover any greenbelt or park space within the proposed development. The irrigation consumption requirement was estimated to be 1 .87 acre-feet/acre and is distributed over the growing season based on plant demands. The irrigation application efficiency was assumed to be 70% resulting in a diversion requirement of 2.67 acre-feet/acre (1.87/.7). An additional demand for 12 livestock was included at a consumption rate of 15 gallons/unit/day. Based on the above assumptions, the peak diversion month would occur in June with a demand of 1.78 acre-feet or 13.4 gallons per minute and the average monthly demand would be 1.18 acre-feet/month or 8.9 gpm. The annual diversion requirement is 14.16 acre-feet. The estimated annual water consumption requirement is 4.35 acre-feet, with 1.53 acre-feet attributable to "in house" uses and 2.81 acre-feet from irrigation and livestock needs. The entire 13 units will require a larger instantaneous peak demand than can be provided for by the well alone. On site storage will be provided to supply peak domestic and fire storage demands. Sizing of storage facilities and associated distribution pipelines will be provided by High Country Engineers. It is our opinion that with proper storage the well will be capable of serving the development's domestic and irrigation needs assuming the aquifer characteristics provide adequate recharge capabilities. We recommend that the aquifer be monitored on a regular basis so that the water resource can be properly managed. During periods of low recharge (like a 1977 dry year), irrigation from the well at the proposed development might require curtailment if seasonal recharge volumes are low. We recommend that a second well be constructed to provide mechanical reliability to the system. The second well should be constructed at approximately 50% of build out of the subdivision. The Levitt Well #1 (Monitoring Hole No. 27419) has been constructed but has not been tested and may be suitable for this purpose.

The legal water supply can be provided from contract water with the Basalt Water Conservancy District. The contract water enables use of district water rights to replace or "augment" diversions from the development, thus protecting any downstream water rights. Diversions from either well would initially be covered under a temporary exchange plan currently approved by the Division of Water Resources. Use of the contract water will eventually require formal approval under a court approved augmentation plan at which time only the consumptive portion of water use will have to be replaced. Well permits from the Division of Water Resources will be approved subject to being covered by the Basalt Water Conservancy District temporary exchange plan. Finally, water samples of the pumping discharge were taken from Levitt Trust Well #2 but have not yet been analyzed by the investigating laboratory. We will make the results available to you as soon as we receive them from the lab. We estimate the laboratory results will be available on April 3rd or 4th 1996.
