Formation of the Spring Valley Sanitation District is recommended so that the developers of Los Amigos Ranch and Colorado Mountain College can cooperative- ly develop and operate one sewage treatment system. The recommended method- ology consists of secondary biological treatment with land treatment as the final disposal method. Chis recommended system complies with the '303e' River Basin Plan guidelines as adopted by the State of Colorado. The facilities have been designed in phases for an ultimate flow of 200,000 gpd (gallons per day). Phase I consists of adding aeration to the existing stabilization lagoons in 1979 at the Colorado Mountain College treatment site to service existing flows from CMC and 96 new apartment units being built in 1979/1980. Phase II consists of constructing an activated sludge type secon- dary treatment facility followed by spray irrigation and infiltration/ - percolation beds in 1980 at a design flow of 100,000 gpd (average daily flow). Phase III consists of expanding the treatment capacity to an ultimate capacity of 200,000 gpd (average daily flow) in 1983/84. Prior to design of Phase II improvements, the ultimate population of the District should be re- evaluated as other potential developers in the area have expressed interest in being serviced by the District. Capital cost estimates were prepared for the three phases based on 1979 dol- lars. Ultimate capital projections were also estimated, based on the 1979 dollar estimate inflated at 8 percent per year. The estimated capital cost in 1979 dollars by phase is: BRANCH OFFICES ASPEN O pox 8028 t'E N, COLORADO 8161 I DILLON LAKE PO BOX 1171 FRISCO, COLORADO 80443 G1 41 NWOUD 'OPHIN(.S P O.

APPENDIX D - LEGAL DESCRIPTION OF THE SPRING VALLEY SANITATION DISTRICT SECTION I INTRODUCTION GENERAL This Preliminary Engineering Report has collected factual data and developed a plan for the formation of a sanitation district in the Spring Valley area of Garfield County, Colorado, to be known as the Spring Valley Sanitation District. Creation of the proposed Spring Valley Sanitation District, hereinafter re- ferred to as the District, is being considered in view of the present and future needs for acceptable sanitary sewer service for Colorado Mountain Col- lege (CMC) and Los Amigos Ranch. The District Service Boundary at inception is indicated on Figure 1-A and described by legal description in Appendix D. Wastewater treatment facilities are to be located at the existing lagoon site, which is currently owned by Colorado Mountain College. The proposed District will own, maintain, upgrade and expand the treatment facility to meet demand in compliance with current standards established by the Colorado Water Quality Control Commission. PURPOSE OF REPORT The objectives of this Report are to: 1. Provide an engineering document which will be used to define the bases for establishing a sanitation district. 2. Describe some of the more salient features of the proposed District system. 3. Evaluate the existing wastewater treatment facilities. 4. Outline the basic proposed operating procedures and rules of the District. In order to meet these objectives, the scope of work includes: • An evaluation of the treatment capability of the existing CMC lagoon system and an estimate of the cost to bring the system to State standards for the ultimate wastewater flows generated by CMC, if there would be no outside development. • An estimation of sewage loads to be generated by the District, based on furnished development plans. I -L 1-3 • An evaluation of the degree of treatment required if a District is formed. This evaluation will include a preliminary system design for development within one year and for ultimate development within the District. • An estimate of capital costs for phased construction of the treatment facilities and an estimate of rates and charges required to support the District. HISTORY Prior to the arrival of the first Spring Valley settlers in the late 1800's, the area was used by the Ute Indians as a summer hunting and food gathering area. Up until 1966 the valley was entirely agricultural in nature. Hay, grains, potatoes, and livestock were the main products and ranching was the way of life. In November 1965, an election was held creating a taxing district to fund the new junior college known as Colorado Mountain Junior College District. Con- struction was completed in the fall of 1967 and the first classes began. The college was built on land donated by Jim and Dan Quigley, Sam Campbell, George Dapples, Jim Nieslanik, Luke Anthony (John Powers property), and a remote hill- side was donated by Pete Cabrinah (Hopkins Ranch) who wanted to be a part of the transaction. A parcel of land was purchased from Bruce Dixson. These donors envisioned not only the college, but the development that is now occur- ring. The college has continued to grow and expand with a new Student Center under construction this summer. The 1968 Garfield County Master Plan designated the Spring Valley area as a "potential urban center." The Los Amigos Ranch was owned by Sam Campbell and George Dapples who used it exclusively for raising winter wheat and running cattle, as well as a home site. It was sold by the Sam Campbell estate to the present owners whose plan 1-4 includes keeping approximately 800 acres in winter wheat. The Los Amigos development has received final plat approval of Subdivision No. 1. Subdivision No. 1 calls for 96 apartment units with construction starting during the sum- mer of 1979 and completior in 1980. Subdivision No. 2 is in the preliminary review phase. Subdivision No. 2 en- visions a total of approx'mately 311 dwelling units, all but 61 of which will be served by the proposed District with construction scheduled to begin early in 1980. The 1971 Brown-Gamba report entitled "Spring Valley, Planning for a College Oriented Community" outlined the necessity for, and concept of, a utility dis- trict for the Spring Valley area development. The idea has been discussed from the beginning in College planning. The Engineers' Report prepared by Barton, Stoddard, Millhollin and Higgins entitled "Sewage Works for Colorado Mountain College, Western Campus, Glenwood Springs, Colorado" states, "If the area surrounding the college site is developed into homesites in the future, the college will attempt to sell the utilities to such a sanitation district." This Service Plan for central sewage collection and treatment has incorporated ideas from all previous proposals.

ESTIMATED WASTE LOADS The development information in Table II -A was used to estimate the future waste loads listed in Table 11-1). TABLE II -D ESTIMATED WASTE LOADS - HYDRAULIC LOADING Colorado Mountain College Los Amigos Ranch Elementary School Average (gal/day) 1979-80 32,000 20,000 52,000 Daily Flow 1990 (Ultimate) 52,000 107,300 10,700 170,000 The treatment facility for the ultimate population of the District should be designed for an average daily flow of 200,000 gallons/day. The initial facil- ities should be designed for an initial hydraulic load of 100,000 gpd in 1980 with expansion to 200,000 gpd in 1983. Since other developers have indicated interest in annexing into the District in the future, prior to the start of final design of the initial facilities (Phase II - 100,000 gpd), the ultimate population to be serviced by the District should be reassessed. Estimated Waste Loads - BOD Loading 1979-1980 1990 (Ultimate) BOD5 lbs/day 104 360 Lake Springs Ranch is a proposed development with borders contiguous to the District boundaries and serviceable by gravity flow. Lake Springs Ranch is in the application stage for P.U.D. approval. If the development plans of Lake Springs Ranch are approved and if they annex into the District, the wastewater loading from the 195 single family homes in the Lake Springs development is estimated at an additional 60,000 gallons per day. EFFLUENT QUALITY Currently there is no discharge from the lagoon system at Colorado Mountain College. When the system is expanded, the alternatives for final effluent disposal include land treatment (spray irrigation and/or rapid infiltration) or direct discharge to Cattle Creek. The land treatment alternative will require soil investigations to determine loading rates in the area of existing and future rapid infiltration basin sites and spray irrigation sites. Effluent will receive secondary treatment and chlorination prior to final disposal by land treatment. Monitoring wells will be installed to moni`:or movement of nutrients through the water table. The direct discharge alternative would require a high quality treatment system before discharge to Cattle Creek. Cattle Creek has been classified by the State as a high quality fishery. Discharges to Cattle Creek would have a limitation on ammonia, in addition to a waste load allocation for BOD5 and suspended solids. DESIGN INFORMATION - LAND TREATMENT An investigation of the characteristics of soils types in the CMC treatment site area was conducted in April and May of 1979 to select land treatment sites and to determine loading rates for infiltration/percolation and spray irrigation sites. Two reports covering these investigations are attached in Appendix B. The Wright Water Engineers Report, dated May 18, 1979, summarizes subsurface investigations performed by Lincoln-DeVore and soils/geologic information from the USBR Basalt Project and the U.S. Soil Conservation Service. The report recommends the following application rates for land treatment: Infiltration/Percolation: 0.2 to 0.5 inches/hour Spray Irrigation: 3 to 5 feet/year The Soil Conservation Service Report, dated May 23, 1979, recommends that crops be grown in conjunction with a spray irrigation program on District property near the sewage treatment plant site. The reports confirm that a combined program of spray irrigation and infiltration/ percolation is a feasible alternative for final effluent disposal for the Spring Valley Sanitation District. II -5 It is assumed that the spray irrigation system would be run during the irrigation season and the infiltration/percolation system during the non - irrigation season. Some effluent could also be stored during the non - irrigation season for later use. SECTION III PRELIMINARY DESIGN OF WASTEWATER TREATMENT FACILITIES EVALUATION OF THE EXISTING WASTEWATER TREATMENT FACILITIES The Colorado Mountain College campus is served by an independent sanitary sewage system. Treatment/disposal is now accomplished using plain lagoons located about 1/2 mile southerly of the campus. The ponds are unsealed and all flow now evaporates and/or exfiltrates to the ground water table. The ponds have an approximate volume of 2 MG each. The first pond was originally designed to be aerated. A 7-1/2 hp mechanical surface aerator was installed, but was never connected to a power source. Because there is no discharge from the pond, the Colorado Mountain College has not been issued a discharge permit. The present sewage flow from the campus is estimated at 32,000 gallons per day. With growth, the College's future sewage flow could increase to the range of 52,000 gallons per day. Based on the State of Colorado criteria for waste stabilization ponds, the existing lagoons are at their system capacity. The State criteria provide that: (a) the pond system must hold the design flow for 180 days, (b) the primary cell should be designed for no more than 0.5 pounds of BOD5 per 1,000 square feet of surface area per day, and (c) there must be a minimum of 3 cells, and the ponds must be designed to operate in both series and parallel. The hydraulic loading criteria of 180 days residence time allows for a total treatment capacity of approximately 22,000 gallons per day. The BOD5 criteria allow for approximately 64 pounds per day of BOD5. The present flow of approximately 32,000 gallons per day and 67 pounds per day of BOD5 indicates that the ponds are overloaded. III -2 In order to upgrade he existing lagoon system to effectively treat the projected flows from CMC, it would be necessary to: • Bring three phase power to the lagoon site. • Replace the existing surface mounted aerator, if required. The existing aerator was installed approximately seven years ago and has never been tested. If inoperable, it must be replaced. Therefore, replacement costs are included in the estimate of capital costs. If the aerator must be replaced, it is recommended that a blower/aerator system be installed to replace the surface aerator. • Install two monitoring wells next to the lagoons to monitor the effluent leaching from the lagoons. • Seal the first pond. (The State may or may not enforce this requirement depending on the information gathered from the monitoring wells.) The estimated capital costs for these improvements is shown in Table III -A.

For this purpose, the College and Los Amigos Ranch have entered into a Sewage Treatment Services Agreement, dated July 2, 1979, which is attached as Appendix A. This will result in general economy of construction and operation. The lo- gical plant site would be located at the present CMC lagoons because: • the site can be reached by gravity flow from most of both areas, • it is an existing facility having site approval from the Colorado Water Quality Control Commission, • the existing ponds have value, • sufficient land is available for the proposed treatment facility, • the site is sufficiently removed from CMC facilities and residential development, • site approval for Phase I improvements was granted by the Water Quality Control Commission on July 2, 1979. The College desires to establish an ongoing program for training water and wastewater plant operators. There is a real need for this type of training, particularly in Western Colorado. It is, therefore, suggested that the pro- posed treatment facility be designed for symbiotic use as a "hands-on" training facility. It is proposed that the treatment facilities expansion be constructed in phases to somewhat match development rates. The following phasing is designed to meet projected development demands. Phase I - Remodeling of the first pond as a mixed aerated lagoon to treat existing flows from CMC and the flows from 96 apartment units to be constructed by Los Amigos Ranch in 1979/80. The average daily flow is estimated at 52,000 gpd. Site approval for Phase improvements was granted by the Water Quality Control Commission on July 2, 1979. 111-4 Phase 2 - Addition of pretreatment facilities and an activated sludge plant designed for an average daily flow of 100,000 gallons per day. The first aerated pond (existing) would be used for storage and as a buffering pond for upsets. The second pond would be used as an infiltration/percolation basin. The soils data (reference Appendix B) indicate that a second infiltration/percolation basin (15,000 s.f.) will be requirec to handle the average daily flow of 100,000 gallons. Phase 1 operating data will confirm the actual pond area required. A spray irrigation system (10 acres)will be constructed for use dur- ing the irrigation season. Monitoring wells or lysimeters will be included. Preliminary design of the activated sludge system was based on the assumption that the RELEX Modification could be used for the initial phase. The RELEX process utilizes a fill and draw technique to eliminate the need or use of a clarifier. This system is based on a cycle which provides that during a certain percentage of each hour, the agitators and air blowers are not in operation. Quiescent condi- tions are established in the aeration basin, allowing solids to set- tle out. The top layer of the basin thus, is clarified. After a preset period of time, the aeration basin discharges. The discharge is decant taken from the top clarified layer of the aeration basin. At the end of the discharge cycle, the valve on the discharge piping closes and the air blowers and agitators return to operation. Dur- ing this portion of the cycle, there is no discharge from the aeration basin. Sludge will be wasted by pumping to sludge drying beds. Dried sludge will be tilled into the ground in the spray irrigation area. A complete laboratory/control area would be provided. III -5 Phase 3 - Increase plant capacity to 200,000 gpd by the addition of a clari- fier and an aerobic digester. Two additional infiltration/percola- tion basins would be added. The size of the spray irrigation system would be doubled to a total of 20 acres. Phase 4 - Addition of an advanced waste treatment plant. Based on the availability o1' Federal and State Grant money, this facility would be added as a training facility for the operator training school at CMC. (As long as there is no discharge to Cattle Creek, this facility is not a required plant operating unit.) The AWT facility would be used to produce a high quality effluent and would feature coagulation, flocculation and filtration. The AWT plant would be run during the winter time when requirements for nitrification are minimal. During the warmer months, the final effluent treatment would be land treatment. A proposed process flow diagram is shown in Figure III- COLLECTION SYSTEM It has been proposed that the collection system be owned and financed by the District. Preliminary design of the collection system based upon the development projections shown in Table II -A and the developer's drawings, give the following phased construction: Size 8 -inch dia.

All cost estimates are based on 1979 dollar levels without al- lowance for inflation. 2. Reduction of total costs have not been made to account for pos- sible grants during the second or third phases. It is antici- pated that the District would be eligible for grants. In order to proceed with Phase IV, a water quality control grant would be obtained. Pursuant to Paragraph 2(a) of the Agreement be- tween CMC and LAR, CMC would participate in the local share of Phase IV capital costs. 3. Pursuant to Paragraph 2 of the Agreement between CMC and Los Amigos Ranch, up to 33 acres of land will be made available by CMC to the District for present and future needs of the District at a cost of one dollar per year. Thus, no capital cost for land acquisition is included in the estimated capital costs for Phases I - IV improvements. SECTION IV OPERATION AND FINANCING GENERAL In order to best finance and operate the proposed utility system, the forma- tion of the Spring Valley Sanitation District is recommended. Under Colorado law, the district would be a quasi -municipal non-profit corporation having mana- gement, taxation, and condemnation powers. A district is governed by an elected Board of Directors of five persons. The District Board would administer the con- struction contracts, operate the system and determine the sources and allocation of income. An important advantage to district formation is the establishment of a permanent operating entity. The residents assume control and operation of their own system and thus assure the continued availability of utility service. The District would service Colorado Mountain College by a service agreement (see Appendix A). This arrangement permits the making of an equitable rate agreement between the District and the College, while not affecting District valuation. In effect, it is proposed that the College trade the value of the existing lagoon system and present and future land requirements by the District for the equivalent of system development fees for the existing student and staff population at CMC. Additional needs of the College in the future will be met by the District upon payment of applicable system development fees.

INCOME REQUIREMENTS District operating income must be sufficient to cover all operation and main- tenance expenses. Estimated annual operation and maintenance costs are listed in Table IV -A. These estimates are based on 1979 dollar values and will have to be adjusted in the future as dollar values change. TABLE IV -A ' ESTIMATED ANNUAL OPERATION AND MAINTENANCE COSTS 1 Salaries 1980 1990 (ultimate) Operator (part time) $ 10,000 $ 15,000 I Bookkeeper (part time) 2,000 9,000 intenance 4,000 5,000 Utilities, Power 6,000 $,000 Chlorine 200 400 TOTAL (at ultimate development) $ 22,200 $ 37,400 1 IV -3 This estimate includes operation and maintenance, labor costs, billing expense, power and heat, chemicals and supplies at complete buildout. It assumes that the Board of Directors would serve without pay. The District's capital income requirements are those required for debt service (until all bonds are retired). RATES AND CHARGES FOR SERVICE The actual rates and charges for sewer service would be set by the elected Dis- trict Board of Directors. Tentative rate and charge schedules have been computed and are presented herein for the purpose of presenting the probable costs of service. Two considerations are significant in the establishment of a rate structure: (1) The rates must produce enough income to sustain system operation, and (2) the rates should be set equitably so that persons will pay for service in approximate proportion to actual benefits. Practical methods of obtaining income for the proposed Spring Valley Sanitation District are discussed following, and recommended initial rates given. SERVICE CHARGES Service charges will be allocated only to operation and maintenance expense for the sewage treatment facility and sewer system (the latter being small). There- fore, charges should be proportional to flow load, assuming nearly comparable sewage strength. It is impractical to meter sewage flows, and therefore, a flat rate schedule is used. In order to equitably allocate costs and provide for simple rate changes, the EQR schedule and billing basis in Table IV -B is recommended. The EQR (equivalent residential unit) system uses an average single family residence as a base unit. The service charge needed at ultimate development is estimated to be $6.50/month at 1979 cost levels. Initially, until more users connect, the cost per tap will be higher. An initial rate of $9.00/month is estimated to be sufficient with a reasonable growth rate. IV -4 System Development Fees A system development fee or connection charge is normally made to new users of a utility system. In this way, a new user pays a portion of his share of invest- ment in the system. For the Spring Valley District, SDF capital income is the primary source for debt service retirement. It is designed at a level so that, with a reasonable tax levy, adequate income will be available for debt service. System development fees should be based on the EQR value assigned to a partic- ular tap. An EQR is represented by a single family residential unit with a resident population of 3.3. An equivalent residential tap can be defined as any utility customer requiring sewer service in quantities approximately equal to 3.3 resident people (or 1 residence). A business establishment with an EQR value of 3.0 would pay three times the established tap fee for a single family residence. It is recommended that the proposed district set the initial system development fee of $4,000 per EQR. Not included in this fee would be the cost of service lines or connections to the main, etc. System development fees should be period- ically reviewed, and priced in accordance with the projected capital needs. Mill Levy A mill levy on property is a common method of obtaining income to support a sewage treatment system. The sewage treatment system becomes a property of the entire District. The availability of sewer service will aid property values throughout the District since, by being in the District, the property has a right to utilize the District's facilities whenever desired and economically feasible. An income based on a mill levy is proportional to relative property values. It has been determined that a 7.0 mill levy will be adequate to repay debt, assuming develop- ment rate as projected. System development fees and the mill levy will be used to pay debt service for capital improvements to the sewage treatment, collection sewer system, and the main trunk line. A Capital Financing Plan has been prepared by Hanifen, Imhoff and Samford, Inc. and is attached as Appendix C. IV -5 Standby Service Charges Standby service charges are not a planned source of income, assuming the develop- ment rate proceeds as predicted and shown in Table II -A. However, should de- velopment slow, the SDF income could become inadequate. It is anticipated that the District would, in addition to increasing the mill levy, require standby charges for platted, but undeveloped, property. Service Area Expansion In the event any of the developers in the Spring Valley area annex to the District or receive sewer service from the District, the financial outlook should be further enhanced, Iv -6 TABLE IV- B PROPOSED EQR SCHEDULE SPRING VALLEY SANITATION DISTRICT 1.

IV -9 RECOMMENDED PROVISIONS - DISTRICT OPERATION It is recommended that the following principles be included in the District's Rules and Regulations. Final wording of those rules and regulations should be developed jointly by the future Board of Directors, District Counsel, District Engineer, and Fiscal Agent. SEWER SYSTEM 1. Service Charges. The majority of service charges will be allocated to operation of the sewage treatment facility. Therefore, charges should be proportional to flow load, assuming nearly comparable sewage strength. It is impractical to meter sewage flows and, therefore, a flat rate schedule is used. In order to equitably allocate costs and provide for simple rate changes, the EQR schedule and billing basis in Table IV -3 is recommended. Sewer service charges will be $9.00 per month of EQR, payable quarterly. 2. System Development Fee. The fee should cover a proportionate share of investment in the interceptor sewer, the collection sewer system, and the sewage treatment plant. A separate charge will be imposed to cover actual cost of inspection of service line connections. The initial system development fee for connection to the Spring Valley Sanitation District sewer system shall be $4,000 per EQR unit. Additions to buildings shall pay tap fees applicable to the addition. The fees only include the making of the tap at the sewer line with all of the service line costs to be paid for by the builder/customer. The system development fee may increase, based on future actual capital costs as governed by inflation. 3. Service Lines. All service lines shall be constructed in accordance with District standards of VCP of heavy PVC pipe. No line shall be bedded or backfilled until inspected by the District. The tap on the District sewer shall be made with an approved watertight saddle by a plumber bonded and approved by the District. Maintenance of sewer I11-10 service lines shall be the responsibility of individual customers, and not the District. Each building and/or customer shall have a separate service line. 4. Use of Sewer System. No customer may discharge water bleeding flows, storm water, surface water, groundwater, subsurface drainage, or unpolluted industrial process water to the sewer system. Customers shall not discharge any toxic chemicals, flammable or explosive substances, unusual amounts of solids, or any other material which is atypical of sanitary sewage of domestic origin and which could interfere with the operation of the sewer system or sewage treatment facilities. All service stations, restaurants, cafeterias or other customers having large quantities of solids or grease in the waste, shall be required to construct and maintain acceptable grease and grit traps prior to discharge to the sewer system. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 APPENDIX A SEWAGE TREATMENT SERVICE AGREEMENT WITH COLORADO MOUNTAIN COLLEGE SEWAGE TREATMENT SERVICES AGREEMENT THIS AGREEMENT is made end entered into this 2Nd day of , 1979, by and between COLORADO MOUNTAIN JUNIOR COLLEGE DISTRICT, a junior college district organized under the Colorado statutes (the "College"), and the owners of the LOS AMIGOS RANCH P.U.D.: ROBERT W. CHATMAS, JAMES A. R. JOHNSON, and THOMAS E. NEAL (collectively "Los Amigos"). RECITALS The College owns the real property described on Exhibit "A," attached heroto ani incorporated herein by this reference (the "College Property"), upon which it is presently operating a sewage treatment facility serving the College operations. This sewage treatment facility is incomplete and is not adequate in its present condition for the College's long-term needs. The Los Amigos Ranch P.U.D. is adjacent to the College Property, and its owners desire to develop the property primarily for residential purposes, and to provide a community sewer system and a community sewage treatment facility for that portion of said property described on Exhibit "B" attached hereto and incorporated herein by this reference (the "Los Amigos Sewered Property"). The topography of the two properties and the location of the Los Amigos Sewered Property indicates that it is feasible and economical to treat the sewage from the two properties at the location of tho existing treatment facility on the College Property. Los Amigos has the necessary approvals to commence construction upon its development during the 1979 building season. Los Amigos is willing to cause the draft Service Plan dated May 18, 1979, prepared by Wright -McLaughlin Engineers, to be revised to exclude the Lake Springs development from the proposed District boundaries. It is intended by the parties hereto that a sanitation district to be named the Spring Valley Sanitation District (the "District") be organized under C.R.S. 1973, Sec. 32-4-101, et seq., as amended, whose service area would be the area within the external boundaries of the College Property and the Los Amigos Sewered Property combined, as shown on the draft Service Plan prepared by Weight -McLaughlin Engineers, dated May 18, 1919 (the "Plan"), atrached hereto and incorporated herein by reference for all purposes, but whose district boundaries would be the boundaries of the property described on Exhibit "C," attached hereto and incorporated herein by this reference. The College desires to commence a sewage treatment facility operators' training program, utilizing the present and future facilities which are the subject of this agreement. The College is willing to permit its present sewage treatment facilities to be upgraded and expanded to provide sewage treatment services to the two properties and to convey its facilities in a manner which recognizes the curriculum potential of the facilities for the College's sewage treatment facility operators' training program. The College also recognizes that the facilities and improvements to be constructed, as generally outlined in the Plan, will enhance the educational experience of the College's sewage treatment facility operators' training program. The College has reviewed the Plan and the capital improvements diacusaed in the Plan and conceptually agrees with and approves of the preliminary design of Phase 1, 2, 3, and 4 capital improvements set forth in the Plan. The College understands that the final Service Plan to be prepared by Los Amigos will delete the Lake Springs Ranch property from the District's boundaries but will in all other material aspects be similar to the draft Service Plan. -2- The College has need of additional student housing and Los Amigos is willing to commence construction upon an apartment project whicn will be rented with availability preference to students ane staff of the College in the renting of such apartment units. It is acknowledged that the College's existing storage treatment facilities, though presently inadequate for its present needs both as to capacity and quality of treatment, could be upgraded by the College to satisfy its present needs and comply with el.igting legal requirements for an additional expenditure of approximately $50,000. It is, therefore, acknowledged that since no system development fees will be charged to the College with respect to its existing level of use, approximately 100 EQR, which the College is receiving in exchange for the conveyance of its existing facilities together with leasehold estates In the land and in the expansion land as described below, the value of the said existing facilities and leasehold estate in the District (or joint facilities as the case may be), will be approximately $125,000. The Governing Committee of the College has found and determined that the real property or interests in real property hereinafter described to be leased and the facilities hereinafter described to be sold and conveyed are not needed by the College In the foreseeable future for any purpose authorized by law, except as provided for herein and on the terms and conditions provided for herein. NOW, THEREFORE, in consideration of the foregoing recitals and of the mutual terms, covenants, and conditions contained herein, the parties agree as follows: 1. Interim Commitment. (a; The College agrees to permit 96 residential apartmec.t units, to be built and owned by Los Amigos, to be connected to its sewage treatment facility as needed, as soon as the upgrading of the College lagoons and the -3- installation of the trunk sewer is accomplished by Los Amigos at Los Amigos' expense as described in the draft Service Plan prepared by Wright -McLaughlin dated May 18, 1979 (hereinafter "Phase I improvements"). Los Amigos agrees that it will contract for the Phase I improvements to bo completed as soon as reasonably practicable, and that it will pay the cost thereof and shall own said Phase I improvements. (b) Los Amigos agrees that prior to commencement of construction it will submit the plans and specifications for the Phase I improvements to the College for its review and approval. Upon submittal to the College, the College shall, within fifteen (15) days, advise Los Amigos in writing that it approves of the plans and specifications or that it disapproves of the plans and specifications stating with specificity the reason(s) for disapproval; provided, however, that in the event the College fails to advise Los Amigos in writing of its decision within the fifteen (15) day time period, the College's, approval shall be conclusively presumed. The College's approval shall not be unreasonably withheld; it being the intent of the parties that: Che College be given the opportunity for input at the final design stage; and that Los Amigos rely on the College's conceptual approval of the Phase I improvements and on approval(s), if any, of the Phase I improvements that may hereafter be given by local, state, or federal governments or agencies with jurisdiction over the subject matter. (c) In the event the College disapproves the plans and specifications, the College shall cooperate with Los Amigos to the greatest extent possible to resolve the College's concern(s) as expressed in the reasons) for disapproval. Upon resubmittal by Los Amigos of the revised plans and specifications to the College, the procedure set -4- forch in subparagraph (b) of this paragraph shall apply. In the event that the College has not approved the plans and specifications for the Phase I improvements within either: forty-five (45) days from the date hereof, or within the fifteen (15) day review period set forth in subparagraph (b) which commenced before the end of the forty-five (45) day term, whichever is lacer; then this entire Agreemen': shall be deemed null and void and of no further force ac'A effect whatsoever. (d) Before commencement of construction, Los Amigos agrees that it will deposit into an escrow account with a bank or other d.sbursing agent mutually satisfactory to the parties hereto, a sum of money equal to the contract amount for the Phase 1 improvements, to be disbursed by the disbursing agent upon pay estimates signed by the Contractor and the Los Amigos consulting engineers. As additional security, Los Amigos represents and warrants to the College that it presently has upon deposit with Garfield County a Letter of Credit, the condition for release of which is the completion of the Phase 1 improvements, together with other improvements associtated with the Los Amigos PUD Development. 2. Conve ante to District. The College is willing to lease its land and sell its facilities to the District, referred to in Paragraph 4, infra, within thirty (30) days after it is formed, upon the following terms and conditons: (a) The District must agree to provide sewerage services to the College to meet the College's existing nd future needs, for as long as the College may request, and that the service charges for such sewerage service will be calculated to include a fair amount for the cost of operation and maintenance of the facilities, and will not include any profit nor any amount to retire capital indebtedness or investment until necessary for, and then -5- only to the extent of, the capital required fur installation of that portion of the Advanced Waste Treatment (AWT) facilities which do not include land treatment. It is expressly agreed and understood that the District's agreement to provide sewerage services to the College includes the provision of sewerage services to others, such as Pinon Alps, to whom the College has heretofore contractually agreed to provide sewerage service; provided, however, that the service charges for such sewerage service to others shall be the obligation of the College, and the College agrees to pay said charges to Che District; provided further that the College may charge and collect fur such sewerage service in whatever manner as the College in its sole discretion desires. (b) The District must agree that with respect to the College's existing level of sewerage use the College will not be charged a system development fee, since the College is presently on-line with an operating system which it is conveying to the District; provided, however, that if the State or other applicable governmental authority requires additional improvements not contemplated in the draft Plan with respect to the existing level of use but because of new. technical or environmental requirements not in existence when the Phase I improvements are Installed, the College agrees to pay the cost allocable to its use. The College agrees that it will be charged a system development fee with respect to sewage treatment services needed beyond its existing level of use; provided, however, that the District must agree that said system development fees shall never exceed the then -applicable system development fee charged by the District for similar extensions of service -6- to now users within the District. The District must agree tha_ the College will never be required to pay special service fees or mill levies; provided, however, that the District may require other users to pay such levies or charges. A11 other property owners who connect to the system wi.hin the service area will be charged system development fees; (c) in consideration for the College's agreement to pay system development fees for sewerage services beyond its existi1g level of use, the District agrees to undertake such capital improvements as are necessary and appropriate to provide sewerage service for the College's future needs, consistent with economic and engineering feasibility, with the final Service Plan, and with approvals of said capital improvements by appropriate federal, state, and local governments and agencies. The College agrees to provide the District reasonable notice of its anticipated needs to facilitate the planning of said capital Improvements; and (d) The District must agree to the following terms and conditions with respect to the lease of the College's land And the sale of the existing College sewerage facilities, together with an easement for the discharge of efflurnt across lands owned by the College, if and when necessary and required, from the treatment facility to Cattle Creek, easements for vehicular access to the treatment facility, and for electrical power and other utilities. To the extent reasonably practicable, the Phase I improvement trunk sewer will be located within the existing staked right-of-way. (1) The College will lease to the District the land, containing approximately four (4) acres, upon which its present sewerage treatment facilities are located; it being agreed by the parties that Los Amigos, shall at its sole expense, have a survey of -7- the existing fence lines around the plant site performed and that the property leased shall be the property so surveyed regardless of the actual acreage. Said lease shall also include such adjacent land, up to a maximum of four (4) acres, as is reasonably required in the future for the secondary treatment facilities to be generally located westerly of the existing plant site and also such additional land generally located westerly of the plant site, up to a maximtm of twenty-five (25) acres, as is reasonably required in the future for winter storage of effluent, for irfiltration areas and for land treatment, all as shown by the final design plans for such improvements as approved by the Colorado State Department of Health. Said lands shall be leased for a lease term of fifty (50) years, together with an option to renew for an additional fifty (50) years, for $1.00 per year rental, by lease instrument containing appropriate and customary anti -waste, insurance, indemnification, anti -nuisance, and maintenance and repair provisions and authorizing the future expansion of the facilities in a manner generally consistent with the final Service Plan. At such time as the additional land is needed and will actually be used for the purposes authorized herein, the District agrees to provide, its sole expense, a survey of the property to be used, which shall then become the subject of addendum to the lease referred to in this paragraph. The parties shall mutually agree upon the location of additional acreage as soon as is reasonably practical. (ii) The existing sewerage facilities owned by rhe College shall be conveyed to the District by good and sufficient general warranty deed and bill of sale, as appropriate, subject to the following terms and at so an -8- conditions: (A) The District's commitment to cause any future expansions of the sewage treatment facilities to be done in such a wily as to maximize their use in the College's operator training program, if any, consistent with the iiteresta of the District and with the maintenance of high quality operations and the campliance with State standards, and subject to t'ie College's willingness to pay any increased casts which would not otherwise be required except for the operator training program. Prior to the installation of additional capital improvements on the land, the designs for the capital improvements must be submitted to the governing board of the College, in order to permit the College to fully explore operator training aspects of the improvements and to request any changes with respect thereto at the planning stage. (8) The District's commitment to permit the College to operete the facilities in connection with its operator training program, if any, et no cost for labor for the work of College employees and students, but utilizing the District -pur- chased utilities services, materials, chemicals, and such other items es may normally be required for conventional operation of the treatment facility, or the District's commitment that in the event the College elects, from time to time, not to operate the system, the District superintendent shall so operate the system as to make it convenient for the College to conduct operator training on the site. -9- (111) At the closing, the College shall convey to the District the existing improvements by good and sufficient general warranty decd and bill of sale, as appropriate. Except as provided for in subparagraph (iv) of this paragraph, title shall be merchantable in the College, free and clear of any lien or encumbrance except easements and rights-of-way for utilities and drainai',e as shown on the survey to be provided by Cranto4', and reservations and restrictions of record. Title shall be subject to no tenancies or use rights of am kind, except the land lease provided for elsewh:re herein. After closing, Seller shall provide Purchaser a title policy issued to the commitment showing merchantable title in the Grantee, as described above and except as modified in the manner provided for in subparagraph (iv) of this paragraph, subject to no tenancies or use rights of any kind other than the land lease provided for herein. Purchaser shall pay all expenses in connection with obtaining such title policy. (iv) As soon as reasonably possible, Los Amigos shall, at its sole expense, provide the College with a survey of the property to be leased to the District. The College, at Los Amigos' expense, and within twenty (20) days after receipt of said survey, shall provide to the Grantee a preliminary title commitment, issued by a title insurance company authorized to do business in the State of Colorado, for owner's and leasehold coverage in standard ALTA Form 8. Los Amigos shall, within ten (10) days of receipt of the commitment, advise the College that it 1s willing to accept title subject to the exceptions or that it objects to the -10- exception(s), specifying with particularity the exception(s) which must be removed. In the event Los Amigos objects, the College agrees, within thirty (30) days, to use its best efforts to correct said defect(s) in title; provided that if said defect(s) rre no removed within the time provided, Los Amigos may, it its sole option, either: (1) waive its objection(s) and the parties shall proceed as provided in this Agreement; (2) declare the Agreement null and void except as to the provisions of Paragraph 1, and Che parties shall proceed as provided for in Paragraph 6; or (3) declare the entire Agreement null and void and of no further force and effect whatsoever. The title commitment and the policy issued thereunder shall have standard exceptions with respect to mechanic's liens, rights of parties in possession, euiements not shown by public records, discrepancies, co,flicta in boundary lines, shortage in area, encroachments, end any facts which a correct survey and visual inspection of the property would disclose, deleted by endorsement; provided, however, that Los Amigos shall, at its expense, provide the information or data required for said deletion and pay the cost of said endorsement or, at Its sole option, treat the standard exception(s) as a defect in title to which it objects, in which case the parties shall proceed as provided in this subparagraph (iv) in the case of such defects. Copies of all documents pertaining to such exceptions and other interests required to be , eliminated must be attached to the commitment. 3. Student Housing. It le the intent of the parties hereto that the students and staff of the College shall, for a period of ten (10) years from the execution date hereof, be given an availability preference by Los Amigos to the 96 -11- apartment units to be built commencing during the 1919 building season. Los Amigos intends Co commence the construction of eight (8) apartment buildings, each containing four (4) two-bedroom units, four (4) one -bedroom units, and four (4) studio units and agrees to give the students and staff of the College an availability preference in the rental of said apartments. The Board of County Commissioners of Garfield County has heretofore approved the final plat (Los Amigos Ranch P.U.D., Phase I, Filing 1) for said apartments conditioned upon and subject to the provision of sewage treatment service; the execution of this Agreement will, in the opinion of Los Amigos, satisfy said condition. Subject to the concurrence of Garfield County, Los Amigos agrees to record said final plat, to commence construction of the apartment units, and to use its best efforts to complete and offer said apartments for rent as follows: two (2) buildings (24 units) by January 1980; two (2) buildings (24 units) by March 1980; and remaining four (4) buildings (48 units) by September 1980.Loa Amigos agrees to periodically notify the College of the anticipated completion date of the apartments. Los Amigos agrees to attempt to coordinate the commencement of the lease periods with the commencement of the College's quarter periods. Los Amigos further agrees to attempt to coordinate the termination of its lease periods of Leases to those persons other than College students or College staff members with the commencement of the College's quarter periods. Los Amigos shall determine the terms and conditions of leases for said apartment units, and Los Amigos shall rent said units in the following manner: A. In the event two or more persons (or groups of persons) with equal qualifications make application to Los Amigos for occupancy of any such apartment unit, the person who is a member of the student body of the College shall be accorded the first right to lease the apartment unit, and the person who is a member of the staff of the College -12- shall be accorded the second right to lease the apartment unit. s. In the event a student or staff member has entered into a lease of an apartment unit as provided for herein, that person shall, absent good cause shown, be permitted to renew the lease for the unit upon terms and conditions deterrined by Los Amigos. C. Los Amigos recognizes that members of the student body and College staff have a need to lease said apartment units for a term of less than one year. Recognizing this need, Los Amigos agrees, upon request by the student or staff member desiring to enter into a lease for said apartment unit, to lease said unit for a nine (9) month lease term with rent payable in an amount per month which results in an aggregate lease payment equal to the aggregate lease payment of twelve (12) month leases; provided, however, that: (i) The lessee of an apartment unit leased on a nine (9) month term as herein provided shall, subject to the written consent of Los Amigos, be permitted to sublease said unit for a three (3) month period imm4diately following said nine (9) month term and said sublease rental payments shall be for the sole benefit of the lessee up to a maximum amount equal to rents paid for the three (3) months the apartment was not occupied by the lessee and after said maximum amount has been paid, all rents shall be for the sole and exclusive benefit of Los Amigos; or (ii) The lessee of an apartment unit leased on a nine (9) month term as herein provided may elect not to sublease said unit to Los Amigos, and Loa Amigos shall, in this event, make such unit available for use by the College upon such reasonable terms and conditions as Los Amigos may determine and all rents received shall be divided in the following manner: -13- One-half (1/2) to Los Amigos and one-half (1/2) to the lessee up to a maximum amount equal to rents paid for ;he three (3) months the apartment was not occupied by the lessee; and after said maximum amount has been paid, all rents shall be for the sole and exclusive benefit of Los Amigos. 4. tlstrtc._Form�tton. (a) LAI Amigos agrees to use its beat efforts to cause the District to be formed as soon as it to reasonably practicable, in accordance with the final Service Plan to be prepare! by Wright -McLaughlin Engineers of Denver, Colorado, cr other mutually acceptable engineers. (b) Such final Service Plan shall be submitted to the College for its review and approval before the Petition for formation of the District is filed with the Court and before the final Service Plan is submitted for action or approval to any local, state, or federal government or agency. Upon submittal to the College, the College shall, within fifteen (15) days, advise Los Amigos, in writing, that it approves of the final Service Pian or that it dis- approves stating with specificity the rea for disapproval; provided, however, that in the event the College fails to advise Los Amigos in writing of its decision within the fifteen (15) day time period, the College's approval shall be conclusively presumed. The College's approval shall not be unreasonably withheld; it being the intent of the parties; that :he College be given the opportunity for input on matters which affect or its concern the College and its students and staff, and operators' training program, its assets and property, the quality, quantity, dependability, and reliability of sewerage service to be provided the College by the District; and that Los Amigos rely on the College's conceptual approval of the draft Plan. -14- (c) In the event the College disapproves the final Service Plan, the College shall cooperate with the Los Amigos to the greatest extent possible to resolve the Collage's concern(s) as expressed in the reason(s) for disapproval. Upon resubmittal by Los Amigos of the revised final Service Plan to the Collage, the procedure set forth in subparagraph (b) of this paragraph shall apply. In the event that the College has not approved the final Service Plan within either: ninety (90) days from the date hereof; or within the fifteen (15) day review period set forth in subparagraph (b) which commenced before the end of the ninety (90) day term, whichever is later; then this Agreement shall be deemed null and void and of no further force and effect whatsoever; provided, however, chat Los Amigos shall be entitled to the benefits conferred by paragraph 1, supra, in the manner and upon the terms and conditions provided for in paragraph 6, infra. 5. Conveyance to District. The College's obligation to convey the presently existing sewage treatment facilities, and to lease the land, together with all easements and rights-of-way, is contingent upon the condition that the District assume and agree to all of the obligations of the District and Los Amigos to the College provided for herein. It is expressly agreed that Los Amigos by executing this Agreement does not have or agree to assume any obligation whatsoever to perform the obligations of the District as set forth in this Agreement. Upon the formation of the District and the sale and lease to the District as provided herein, Los Amigos shall continue to perform only the obligation set forth in Paragraph 1, and Los Amigos shall be released from all other obligations hereunder. 6. Joint Venture. If for any reason, the District has not been formed before the expiration of six (6) months from the -15- date hereof, unless the parties hereto mutually agree to extend said six (G) month period of time, the parties agree to enter into a Joinc Venture to own and operate the then -existing sewage treatment facilities including those portions of trunk sewers located topographically below the point where more than one entity might have connections thereto, together with all easements and rights-of-way necessary or convenient for the operation thereof, and together with a leasehold estate in the Joint Venture substantially similar to that provided for in Paragraph 2 above. The parties hereto agree to transfer to the Joint Venture such facilities, easements, rights-of-way, and the leasehold estate, in accordance with their respective ownership interests, within eight (8) months from the date hereof, upon the same terms and conditions set forth in subparagraphs (2)(d) above, and upon the following additional conditions: (a) The Joint Venture must agree to obtain appro- priate connector agreements from the College and Los Amigos and the owners of any other property which the Joint Venture permits to connect to the sewage system. (b) Both Venturers must agree to cause to be recorded in the office of the Garfield County Clerk and Recorder covenants, running with the land affecting the College Property and the Los Amigos Sewered Property, which will create lien rights upon such property to secure enforcement by the Joint Venture of its rights under the connector agreements provided for in subparagraph (a) above. (c) Both Venturers must agree to permit the expansion or upgrading of the existing facilities owned by the Joint Venture as may be required by the future requirements of any applicable governmental authority or as may be required to accommodate the expanding needs of either Venturer for additional sewerage services, and to pay the costs thereof in proportion to its then prior and future use of the joint facilities calculated in an equitable manner. -16- (d) Both Venturers must agree that prior to commencement of construction for the expansion or upgrading of the joint facilities, the party or parties participating therein will deposit its share of the construction costs with a mutually agreed upon disbursing agent, to be disbursed upon pay estimates signed by the contractor and the consulting engineer hired by the Joint Venture. (e) Both Venturers must agree that the assets, real and personal property and accounts receivable of the Joint Venture shell not be pledged or encumbered nor used in any way Lo secure credit for the Joint Venture or the parties thereto without the prior written consent of both Venturers; provided further that both Venturers shall execute appropriate instruments, which shall be recorded with the Office of the Clerk and Recorder of Garfield County, to provide notice of the terms of this subparagraph (e). 7. Petition for Inclusion. The College agrees not to petition for inclusion into the District at any time before the expiration of ten (10) years from date hereof; provided, however, that the College shall be entitled to all rights, privileges, and benefits accorded members of the District or accruing to residents or owners of real property within the District to the extent permitted by law. 8. In the event the approval of any local, state, or federal government or agency is required to accomplish the conveyances, transfers of interest, etc., necessary to implement this Agreement, Los Amigos agrees, at its sole expense, to use reasonable efforts to secure such approvals; provided, however, that the College agrees to cooperate as may be necessary to secure such approvals; provided further that upon the formation of the District and the conveyance and lease to the District by the College, the obligations set forth in this paragraph shall be the sole and exclusive responsibility of the District. -17- 9. In the event the time required by Los Amigos to secure or prov_de information, surveys, or other data makes it Impracticable to close within the time period provided for above, closing shall occur as 'loon thereafter as 1s reasonably possible upon thirty (30) days notice to the College by the District that it is ready to close; provided, however, that in no event shall closing occur later than six (6) months from the date here..f unless extended by mutual agreement. 10. Specl.ic Performance. It is specifically understood and agreed that the rights acquired by each party hereto and by the District ale such that the failure of the other party to perform its obligations hereunder would do irreparable harm to the nondefaulting party, and there would be no adequate remedy at law. Accordingly, it is agreed that, In addition to any other equitable or legal remedies, the obligations of the parties hereto shall be specifically enforceable by any Court of record in the State of Colorado. 11.

TAFELSKI TO: John Hopkins FROM: Dick Johnson (nlin. DATE: May 18, 1979 SUBJECT: Los Amigos/CMC - Proposed Land Treatment Site The purpose of this memorandum is to summarize studies and findings regarding hydrologic aspects of the proposed Los Amigos/CMC land treatment project. The proposed site is located in the NWS of Section 9, T7S, R88W, 6th P.M. Existing facilities at the site include two treatment lagoons approximately 120 feet by 120 feet each. SOILS/GEOLOGIC INFORMATION Existing and published soils and geologic literature has been reviewed for pertinent, site specific information. Generally speaking, site geology consists of unconsolidated surficial deposits overlying basalt bedrock formations. The unconsolidated surficial deposits are characterized as older alluvial materials transported by water and/or ice. These deposits vary from boulders to clay sized particles. The under- lying basalt bedrock commonly exhibits columnar jointing and is vesicular. Quite often the bedrock surface is fractured. Limited soil profile information is available from the USBR Basalt Project. Records on file indicate that two project test holes were drilled in the NA of Section 9, with the following logs: AP -45, NWS, Sec. 9, T7S, R88W Depth (feet) Description 0-2 Red clay loam, granular structure 2-4 Red, heavy clay loam, weak granular to massive, fair permeability 4-9 White/pink clay loam, moderately dense and compact, fair to good permeability, very high lime, some basalt rock 9 Refusal - basalt bedrock, dry hole. Subsurface drainage good; test hole apparently located on hillside with 13% slope. -2 - Memo -John Hopkins May 18, 1979 AP -46, NW4, Sec. 9, T7S, R88W (June 23, 1976) Depth (feet) Description 0 - 0.25 Brown clay loam, weak granular to massive, moderately compact 0.25 - 6 Gray/brown clay, massive structure, moderately compact, fair permeability 6 - 10 Red clay loam, massive, moderately compact and dense, fair to good permeability 10-15 Red, heavy clay loam, massive, compact and dense, fair to slow permeability 15-16.5 Mottled, white/red clay loam, massive, moderately compact and dense, fair to slow permeability, some lime 16.5 - 21 21 - 24 24 Red, silty clay loam, massive, compact and dense, slow permeability Mottled, red/white silty clay loam, massive, compact, and dense, high lime, slow permeability Stopped in soil material, dry hole The Soil Conservation Service previously classified site soils as an unnamed silt loam (mapping unit 70) and Jodero loam (mapping unit 52). According to recent information, the SCS is in the process of re-examining previous, tentative classifications in the area. However, the tentative results provide some information regarding characteristics of the near surface soils. The following is a summary of pertinent information from survey data: (52) Unnamed silt loam o moderate permeability (0.8-2.5 inches/hour) o loam classification; 7-27% clay, 28-50% silt o high organic matter content o erosion hazard on bare, steep slope would be high (70) Jodero loam o moderate permeability (0.8-2.5 inches/hour) o loam classification; 7-27% clay, 28-50 silt o clay loam classification; 27-40% clay o cropland and hayland uses Recent (April 22, 1979) site investigations by SCS personnel have provided the following summarized soil information: Memo -John Hopkins -3- May 18, 1979 1 Surface soil is dark brown to very dark brown silty clay loam to clay loam about 28 inches thick. 2. Subsoil is clay loam to heavy clay loam about 19 inches thick. 3. Underlying material is heavy clay loam. 4. Calcium carbonate detected about 28 inches in depth. 5. Permeability is estimated as moderate (0.6 - 2.0 inches/hour) to moderately slow (0.2-0.6 inches/hour) 6. Roots were found to 60 inches. 7. Soil is considered deep and well drained. Based on the above, it is apparent that soil permeability is rather slow, ranging from 0.2 to 2.0 inches/hour. Conservation personnel felt that site soils were, in general, good soils for irrigation and raising crops. Also, it is expected that the underlying fractured basalt bedrock aids in draining the profile. SUBSURFACE INVESTIGATIONS Subsurface investigations were initiated by Wright Water Engineers/Wright- McLaughlin Engineers during Spring 1979. On April 25, 1979 Lincoln-DeVore drilled five exploration holes on the proposed site and installed piezometers in three of the test holes. Table 1 is a summary of the soil profile logs as defined by Lincoln-DeVore personnel. No special laboratory analyses have been performed on soil samples collected during the exploration phase. However, samples will be retained at the labora- tory for approximately three months in the event special tests are required. Natural moisture content of soil samples was determined in the laboratory, and were reported as follows: Moisture Content (W0 in a) Depth 1 2 3 0-5 10.2 22.2 20.8 5-10 33.4 16.0 12.5 10-15 13.9 19.4 11.9 15-20 13.8 16.8 10.8 20-25 20.8 10.9 13.7 25-30 16.6 16.0 30-35 15.5 LINCOLN DeVORE DRILL LOGS >- N TEST HOLE 3 W J O to U to C"O co T a) I11 L L — > (1) O — (D L 4) C - c0 X O >- T N (0 (0U L .

Map 1 shows the approximate location of the test holes. All holes were drilled to bedrock (refusal). Piezometers were installed in test holes 1, 2 and 3. Bedrock depths ranged from 25 to 40 feet. Piezometers consist of PVC pipe, 10 feet of perforations at the bottom, and sealed with bentonite. On May 14, 1979, water levels in the piezometers were measured, with the following results: Test Hole Number Observations 3 35 feet to water from ground surface, only 2-3 inches of water in bottom 2 20 feet to water from ground surface, only 1-2 inches of water in bottom 1 4 & 5 dry no piezometer On May 15 and 16, 1979, three leach field type percolation tests were conducted at the site. Location of the tests is shown on Map 1. Each test pit was ex- cavated to a depth of 30 inches and allowed to soak over night. Results of the percolation tests are as follows: Test Pit Percolation Rate (inches/hour) A 0.5 g 1.0 C 0.75 DISCUSSION All indications at this time suggest that the soils adjacent to the lagoon site should be suitable for spray irrigation. Currently the SCS isdeveloping ' an irrigation schedule and cropping management plan assuming spray 9 and an ultimate design flow of 250,000 gpd. Their recommendations will probably be developed along the lines of maximum utilization of available water, and not necessarily the most economic system for the sanitation district. However, we should be able to take their report, and with appropriate adjustments, develop an economical program. The SCS personnel indicated some interest in being in- volved with the project in the future, possibly on a demonstration basis. Their report should be available sometime during the week of May 21st. Gross annual irrigation applications may be in the range of 3 to 5 feet/year, depending on length of irrigation season and water tolerance of crop. In any event, infiltration basins coupled with spray irrigation will provide necessary flexibility for irrigation scheduling. -6 - Memo -John Hopkins May 18, 1979 The soils in general appear to have excellent characteristics from a waste- water treatment standpoint. Sufficient clays are present in profile to provide final effluent treatment by adsorption, fixation, and filtration. Also, organic matter content is fairly high (about 1+i), which will add to soil fixation capability. Infiltration characteristics of the soil are more difficult to deal with. Current monitoring of piezometers near the existing lagoons indicates that a ground water mound has not developed at the site. Seepage from the lagoons may be insufficient to create a "free" water situation. On the other hand,seepage from the ponds may be percolating into the fractured basalt bedrock rather than spreading later- ally and building up a mound. Based on the recent percolation tests and SCS data, it appears that 0.2-0.5 inches/ hour may be an acceptable range for design infiltration rates. A system designed on this basis should not be referred to as "rapid" infiltration, but rather "infiltration -percolation". Based on this range of infiltration, the following treatment area is required: Infiltration Rate 0.2 inches/hour 0.5 inches/hour Required Spreading Area (acres) @ 55,000 gpd @ 250,000 gpd 0.42 1.9 0.17 0.77 Additional design information regarding infiltration capacities can be gained by observing the operation of the two existing lagoons. It is my understanding that the second lagoon never reaches capacity and overflows, and at times flow is insufficient to pond water in the second lagoon. However, on May 14 both lagoons had ponded water. The May 1979 Service Plan indicates that current CMC flows are about 32,000 gpl. It is assumed that the bottom surface area of each lagoon is about 14,400 ft , Based on these assumptions, additional infiltration capacity information is as follows: Infiltration Area (ft 2) Infiltration Rate (inches/hour) 14,400 (1 lagoon) 0.15 28,800 (2 lagoons) 0.08 Under actual operating conditions, the lagoon bottom area may have become partially sealed from the build up of sludge deposits over the years. Also, the above calculations do not take into account evaporation from the water surface, which will be minimal during winter operation. From all the above information, it seems reasonable to assume a conservative design infiltration rate of 0.2 inches/hour for the percolation basins, provided that bottom sludge deposits can be minimized Based on 0.2 inches/hour, Treading basin area required would be about 18,000 ft at 55,000 gpd and 40,000 ft at 125,000 gpd. Memo -John Hopkins May 18, 1979 -7- 1 would recommend that lagoon seepage losses be monitored under Phase 1 to determine acutal measured losses. This can be done by installing a staff gage in the lagoon and metering inflows. It would be preferable to monitor during the winter time or during minimal evaporation.

The approximate locations for these test borings are given on the enclosed diagram. Logs of the test borings are included with this letter. Field piezometers were installed in Borings 1, 2, and 3. For each of these three borings, an additional boring was made adjacent to each boring, in order to ensure that actual refusal on bedrock was encountered, rather than apparent refusal on an isolated boulder. In Test Boring 1., initial refusal was en- countered at 30 feet depth, and second refusal at 40 feet depth. In Test Boring 2, initial refusal was encountered at 21 feet, and second refusal at 23.5 feet depth. In Test Boring 3, initial refusal was at 37.5 feet depth, and second refusal at 39 feet depth. Borings 4 and 5 were located in proposed treatment areas, and no piezometers were set. Descriptions of the various strata encountered are shown on the enclosed logs. The descriptions and classifications were on a visual basis, and no laboratory classifications have been per- formed. Actual laboratory classifications may differ slightly. Samples have been retained by the Laboratory and additional testing can be performed if desired. These samples will be kept for a minimum of 90 days past the date of this letter, unless otherwise requested. Moisture tests were performed on samples from Borings 1, 2, and 3; and moisture percentages are shown on the logs for these borings, to the right of the sampling points. 2700 Highway 50 West Pueblo, Colo 81003 (303) 546-1150 P O Box 1427 Glenwood Springs, Colo 81601 (303) 945-6020 109 Rosemont Plaza Montrose, Colo 81401 (303) 249-7838 P 0 Box 1882 Grand Junction, Colo 81501 (303) 242-8968 P.O Box 1643 Rock Springs, Wyo 82901 (307) 382-2649 Sundesigns May 17, 1979 Page 2 We hope this has provided the information you desired.

Box 1286 Glenwood Springs, Colorado 81601 Dear Mr. Johnson: Here is some information concerning crops and irrigation on the C.M.C. property near the sewage plant. 20 acres of alfalfa requires 108 gpm continuously during the peak consumptive use period (mid summer). In full operation you will have 174 gpm available. The amount of water you have access to will irrigate 32-33 acres of alfalfa adequately. (See pages 2 & 3) If the alfalfa is watered excessively, a problem with wet foot disease may arise. It must be kept in mind that the crop will require 108 gpm only during the warmest part of the summer. Spring and Fall consumption will be less. MAY 2 4 1979 " May 23, 1979 I think it may be possible to use all the available water on alfalfa as long as it is possible to let the alfalfa dry out once in awhile. Utilization of all the water would involve irrigating .5 acres/setting instead of .32 acres/setting, at the same application rate of .75"/hr. With this system it would take 15.5 days to get through 20 acres. It is important that the system allows for periods up to a week in length that the water can be shut off. These periods will be needed for harvesting and during rainy periods. The other suggested crop is Garrison Creeping Foxtail. It is a water tolerant grass that produces high quality hay. Irrigated with 17J gpm (20 acres) with the same system as forementioned for alfalfa, the grass should produce well. If you need any further information on things such as seeding rates crop management, etc., please feel free to contact me. Sincerely, Ed Neilson, Jr. Soil Conservationist EN/te Encl.

Partners at LDS Amigos Development Garfield County, Colorado Dear Mr. Chatmas: I have prepared the attached Capital Financing Plan for the proposed Spring Valley Sanitation District. I have received construction estimates from Wright -McLaughlin Engineers for three phases of construction to include the financing of the internal lines of the sewer system. I have received estimates from Willson & Lamm, Bond Attorneys, for their fees to establish the District, prepare official statements and render tax opinions. I have included a 3-% underwriting discount as agreed upon by our contract. One year's capitalized interest at a rate of 8% has been included in the bond issue. It is proposed that there be two bond issues: One in 1979 for $1,180,000 and one in 1983 for $440,000. It should be noted that all estimates are in 1979 dollars and the interest rate assumed for all bonds is 8%. Inflation is likely to cause an increase in the 1983 bond issue and interest rate, thereby requiring the need for a slightly higher tap foe. The engineering estimates exclude any construction estimates for the annexation of the Lake Springs area. These numbers are used to determine the financial feasibility of the project. The same numbers are not to be considered maximum bond issue amounts to be voted upon by the electorate of the District. I am proposing a fifteen -year level debt service for each bond issue. Any fund balance to be generated will be reinvested at a rate of at least 8% for use in repaying debt service. The assessed value is estimated at 20% of the projected market value in 1979. This is based on the County Assessor's estimates of the relationship of market to assessed valuation. The 1979 market value estimate of property to be built within the District is based on the developer's estimates. Operation expenses are excluded frau this Capital Financing Plan along with any revenue expected to be generated by a monthly service fee. This Capital Financing Plan is designed to repay proposed debt service from tap fee charges and a mill levy. Assuming growth will proceed as projected by the developer, a tap fee of $4,000 must be imposed plus seven mills of property tax on the assessed valuation. If all of the above-mentioned assumptions are correct, it is my opinion that the attached Capital Financing Plan demonstrates the financial MEMBER NEW YORK STOCK EXCHANGE, INC. Hanifen,Inthoff& Samfrrd, Inc. Mr. Robert W. Chatmas, D.D.S. July 9, 1979 Page 'No feasibility of this project. I believe we have been sufficiently conservative in these projections to insure the ultimate financial success of your proposed District.
