September 26, 2011 Ms. Laura Fawcett Eagle 'County Environmental Health Department L PO Box 179 500 Broadway Eagle; CO 81631 RE: Minturn Cemetery District: Septic System Dear Laura: Enclosed foryour review is the site plan, application and permit fee for the proposed onsite wastewater treatment system for the Minturn Cemetery District (District) and the Town of Minturn's public works building. Currently, there is no potable water supply or wastewater system for the two facilities. It is the intention of the District to provide a potable water supply system through the installation of a well with the associated wastewater system being provided through a 6000 gallon holding tank. The District has secured an Exempt Commercial Well Permit from the State Engineer's Office and has received approval from the -Town of Minturn for the Watershed Permit which was previously submitted. As you will see fro 11 p it the District and the public works facility are limited in'water use 108,600 al/hr d can only use the water for potable water use and wastewater efflue 'gation use, truck washing facilities, etc. are strictly forbidden by the terms and conditions of the well permit. Estimated water demands and a design report have been included in the MinturnWatershed-Permit (re: enclosure): While'a number of wastewater treatment systems were evaluated, the depth of a proposed absorption system ruled out a traditional septic system approach., Further, AEI investigated a dosing system approach but ruled this type of system as being somewhat impractical due to the sensitive environmental conditions which are present i.e., the proximity of the gravesites to ,the absorption -system. It was viewed by our office, the District and the Town that the most practical approach would. be the installation of a Bolding tank which would, be, monitored and maintained by the District. The`District will contract directly'with a septic system pumping contractor for routine maintenance and pumping. P.O. Box 4603 • Frisco, Colorado 8044 • (970) 453,-6064 • Fa c-(70) 453-6631 The holding tank will have float controls which will monitor the tank effluent levels.. The District currently, has a security system and modem which are monitored by Vail Security. It is anticipated that the same security system will be utilized for" monitoring the tank levels and a list of contacts, will be provided by the District as to when the tank needs to be pumped. Given the small wastewater flows which will be generated by both the District's new mausoleum and the Town's public works. facility, we anticipate that the holding tank will only require pumping every 4-6 months. Again, the District will contract directly with a septic system contractor and establish a pumping schedule every 2-3 months just to eliminate the need to rely on the float controls alone. Certainly, the District's caretaker and District Administrator will be on Vail Security's list of individuals to be notified should that need be required. Please do not hesitate to call .our office should you have any questions or comments. cerely, )ames McNeil, PE JM/la Enclosure _ 2 Alpine Engineering, Inc.

MINTURN CEMETERY DISTRICT WATERSHED PERMIT APPLICATION As part of the next phase of the Minturn Cemetery District's expansion plans, the District - would like to: 1. Expand the cemetery site to include the upper bench adjacent to the new mausoleum. - 2. Install a septic system. 3. Install a well, water treatment facilities and a 4-inch potable water line. 4. Extend the existing irrigation system. 5. Remove the existing metal storage sheds (2) and replace them with a new pre- fabricated steel shed. The above -referenced improvements are more particularly described as follows: - 1. Cemetery Site Expansion The upper bench, immediately adjacent to the new mausoleum, will be graded to provide for approximately 300 additional grave sites. The site will have some asphalt paved y paths as well as gravel paths for maintenance equipment and pedestrian access. All paths will be ADA accessible. In order to regrade the upper bench to make it ADA accessible, a new retaining wall will be required. The new wall will essentially parallel the existing boulder wall which is in -place and will vary in height. The appearance of the new wall will be similar to the existing memorial wall at the mausoleum. The regraded upper bench will be completely revegetated. Minturn Cemetery District Watershed Permit Application 1 U. aw ENGINEERING INC. 2. Septic System Currently, there is no sanitary sewer collection system for the District's r the WIffift. The nearest connection point for sanitary sewer service is in Hwy 6 which is more than 1200 feet from the District's property. A connection to the Town's sanitary sewer system would require a Hwy 6 road cut, a bridge crossing and a bore under the existing railroad tracks. The District view the installation of a sanitary sewer main as being cost -prohibitive. Combined wastewater flows from the mausoleum and the Public Works building have been estimated at 75 gpd or 0.0003 cfs. It is highly unlikely that such a minor wastewater flow would even reach a connection point with the Town's system in Hwy 6; there is simply not enough effluent to establish a self -cleansing velocity of 2 fps. Given the above considerations and given the sensitive environmental concerns at the cemetery, AEI is recommending the installation of a 6000 gallon holding tank. The holding tank will be approximately 8-feet wide and approximately 12-feet in length. The depth of the tank will be 8-feet deep and will have approximately 7-feet of cover over the top of the vault. The inside and outside of the tank will have a bituminous coating to prevent the possibility of groundwater intrusion or the leaking of sanitary sewer effluent to the surrounding ground. Float switches will be installed in the tank which will signal when the tank needs to be pumped. The signal will be monitored from the new maintenance building. AEI has reviewed several septic system approaches with the Eagle County Environmental Health Department to determine the most efficient and environmentally sensitive system available. They concur with the installation of a holding tank as the most practical approach. The District will monitor and maintain the system. A plan and profile of the proposed system has been included with this application. Minturn Cemetery District Watershed Permit Application 2 ALPI ENGINEERING INC. 3. Water System The proposed water system will be comprised of a new well, water treatment facilities and a proposed 4-inch DIP water line. A Request for Variance from the Town's Code has been submitted with this Watershed Permit Application. A copy of the well permit and design report for the State Engineer's Office have been included as an appendix to this application. 4. Irrigation System The District will extend the existing cemetery irrigation lines to provide service to the newly established upper bench adjacent to the mausoleum. The new lines will be installed from a tap to the existing 2-inch irrigation line. 5. Storage She The existing storage sheds (2) at the cemetery are in a state of structural disrepair and will be replaced with a new pre -fabricated steel building. The facility will be 200-square feet and will be located in close proximity to one of the existing sheds. The District will work with the Town to insure that the appearance of the building is consistent with Town standards. SUMMARY The Minturn Cemetery is approximately 1250 feet from the Eagle River. The proposed improvements will add very little impermeable area and consequently virtually no increase in developed runoff. Historic drainage patterns will be maintained. Soil profile holes have been drilled where the proposed maintenance building will be located and Minturn Cemetery District Watershed Permit Application 3 INE im ENGINEERING INC. where the proposed retaining wall will be constructed. The geotechnical studies will - determine the bearing capacity of the existing soils for the construction of the proposed structural facilities. The geotechnical reports have been included as an appendix in this permit application. To the best of our knowledge and belief, there are no point or non -point emissions or discharges into the air or water. Vehicular and motorized traffic is limited to periodic maintenance and funeral services.

LOCATION The Mintum River View Cemetery is located in the NE 1/ of Section 35, Township 5 South, Range 81 West of the 6th Principal Meridian in Eagle County, Colorado. The cemetery site has been re -platted over the years and is currently comprised of Lots 1, 2 and 3 and Parcel A. The proposed well site is currently located in Lot 2 which was formerly the Addition to the River View Cemetery located in the North 1/2 of the Northeast 1/ of Section 35, Township 5 South, r' Range 81 West of the 6ti' Principal Meridian in Eagle County, Colorado. The property was conveyed to the Cemetery District in 1967 and recorded in Book 211, Page 705. A deed conveying this property to the Cemetery District and a legal description have been included as part of the application package. i _ The Minturn Cemetery site is situated on the east side of Highway 6 and the Eagle River. The cemetery site is bounded on the southwest by the Union Pacific Railroad and associated 200-foot right-of-way, on the north, east and west (Parcel 7) by the Town of Minturn and on the southeast by the Town of Minturn's Public Works building. The Cemetery site is approximately 1200 feet from the intersection of Highway 6 and Cemetery Road (Ballpark Rd). H. PROJECT NECESSITY As previously stated, the River View Cemetery and the Town's Public Works building are r, located on the east side of Highway 6 and the Eagle River. The sites are approximately 1200 feet from an existing intersection with Highway 6. Currently, there are no water or sanitary sewer services available on the east side of the river. The available connection points are located in the Highway 6 road platform. May 2011 wlint=-CemeteryWeIl Permit Application Report _ 1 In the fall of 2010, construction of a new cemetery mausoleum was completed and included the installation of a mausoleum restroom with a sink and toilet. The infrastructure to connect the water and sanitary sewer facilities was installed at the time of construction but, lacking a source of potable water, the restroom cannot be used nor can the restroom in the Public Works building be used. The District and the Town have evaluated the cost to extend the water and sanitary sewer lines the 1200 feet from Highway 6. Inasmuch as these costs would include crossing the Eagle River and boring under the Union Pacific Railroad tracks the construction costs became prohibitive. The District also evaluated the possibility of installing a potable water storage tank T, and purchasing the water from a commercial provider. This system would require the installation of a water distribution pumping system with associated alarms and controls. This approach presented numerous construction and operational issues. The cemetery site is limited in available space as much of the site is currently allocated for existing and future gravesites. The amount of space necessary to bury a water storage tank is prohibitive. Further, we anticipate the water demands for the Cemetery and the Public Works building as being exceedingly low. The issue of the stored potable becoming stagnant, over time, is viewed as acute and would necessitate the need to retrofit the existing bathrooms in the mausoleum and the Public Works building with i some sort of UV disinfection system. Inasmuch as the proposed water facilties will be located on Cemetery District property and infrequently used, inspection and monitoring of water storage levels and water quality would be difficult. To that end, the District feels that the most reliable and efficient means of providing water i is through a well system. Depending on the well water quality, sufficient disinfection facilities will be installed to comply with all State requirements. It is hoped that the Town, in consideration of 2 Mintum Cemetery Well Pcmn t Application Report a potential connection, will help maintain the system. If the Town does not wish to assume the responsibility, the District will contract with a licensed operator to provide monitoring and maintenance for the facilities. Wastewater services will be provided through an on -site septic tank and absorption field. The infrastructure to accommodate sanitary sewer flows is currently in place and will be sized to serve the mausoleum and the Public Works building. The septic system will be located on Cemetery District property and will be designed and constructed under the auspices of the Eagle County Environmental Health Department. All of the required easements and intergovernmental agreements between the Town and the District will be provided as required. M. PROPOSED IMPROVEMENTS Currently, power, phone and gas service are available to the Cemetery site. The nearest water and sanitary sewer facilities are located in Highway 6, approximately 1200 feet from the Cemetery site. It is cost -prohibitive to extend these utilities to the site. To that end, the District would like to install a well, on its property, to provide water service to its newly constructed mausoleum and if possible the Town's Public Works building which currently has no water or sanitary sewer facilities. The newly constructed mausoleum has a single restroom with provisions for potable water and a single toilet. The on -site water and sanitary sewer infrastructure was installed as part of the y mausoleum construction and was designed to provide future service not only to the mausoleum _ but to the adjacent Public Works building. While the Public Works building is clearly on Town property, its proximity to the common property line with the Cemetery would suggest that ~ inclusion of the Town's facility be incorporated in the Cemetery District's well permit application.

The District is aware that the pumping requirements for a Commercial exempt/small capacity are limited to drinking and sanitary purposes only. Water usage is limited'to 1/3 acre-feet annually (108,600 gal). Ultimate discharge of sanitary sewer waste for the mausoleum and the Town's Public Works building will be to an on -site septic system with an absorption field. The facilities will be installed by a licensed septic system installer under the auspices of the Eagle County Environmental Health Department. T IV. WATER USAGE Projected water demands for a Commercial exempt/small capacity well have been estimated per the form GSW-57 worksheet and included as part of the application package. For estimating purposes we have included water consumption demands for the mausoleum use as well - as the Public Works building. In estimating water demands for the Pubic Works building, we have been informed by the 1 Town that there are currently three (3) employees that use the facility. To accommodate future growth we have estimated water demands for five (5) employees which is shown under 4. EMPLOYEES on the GSW57 worksheet. Water usage for the mausoleum has been estimated at three (3) funerals per year (District records) with 12 attendees per funeral (36 total per year). For demand estimates, this translates to 1 person per day for 365 days and is shown under 4. CUSTOMERS on the GSW-57 worksheet. May 2011 Minturn Cemetery. Well Permit Application Report 4 Total annual demand for the mausoleum and the Town's Public Works building are 24,600 gallons per year (0.08 ac/ft per year). In accordance with the requirements for a Commercial exempt/small capacity well permit, water consumption is limited to drinking and sanitary purposes only.

The project site T is shown on Figure 1. The purpose of the study was to develop recommendations for foundation design. The study was conducted in accordance with our agreement for geotechnical engineering services to Alpine Engineering, dated July 7, 2011. The agreement was verbally modified by Jim McNeil to include an additional boring and design parameters for a proposed mechanically stabilized earth (MSE) retaining wall. r, A field exploration program consisting of exploratory borings was conducted to obtain information on the subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to determine thei classification, compressibility or swell and other engineering characteristics. The results of the field exploration and laboratory testing were analyzed to develop recommendations for foundation types, depths and allowable pressures for the proposed building foundation. r Recommended design parameters for the MSE wall are included in the report. This report summarizes the data obtained during this study and presents our conclusions, T, recommendations and other geotechnical engineering considerations based on the proposed construction and the subsurface conditions encountered. PROPOSED CONSTRUCTION The maintenance building will be located near an existing shed in the northwest portion of the cemetery as shown on'Figure 1. The building will be a single story steel frame and metal pre-engineered structure about 10 feet by 20 feet in plan size. The floor will be slab -on -grade. We assume excavation for the building will have cut depths from about 3 to 5 feet below the existing ground surface. For the purpose of our analysis, foundation loadings for the structure were assumed to be relatively light to moderate and typical of the proposed type of construction. _ Job No. III I95A orteCI"1 -2- The MSE wall will replace an existing boulder wall located about 400 feet southeast of the maintenance building site along the east side of Cemetery Circle. The wall will retain fill and be from about 4 to 12 feet tall. If building or wall loadings, location or grading plans are significantly different from those described above, we should be notified to re-evaluate the recommendations contained in this report. SITE CONDITIONS The maintenance building site is in the northwest portion of the cemetery where two existing sheds are located. The ground surface has apparently been cut some. The terrain is strongly sloping down to the southwest. Elevation difference across the assumed building area is about 3 or 4 feet. Vegetation consists of grass and weeds with scattered trees. At the MSE wall site, the terrain is moderately steep sloping down to the southwest. The existing boulder wall in this area, along the east side of Cemetery Circle, is about 4 to 5 feet tall. FIELD EXPLORATION The field exploration for the project was conducted on July 14, 2011. Two exploratory borings were drilled at the locations indicated on Figure 1 to evaluate the subsurface conditions. Boring 2 was drilled at the proposed maintenance building site as shown on Figure 1, and Boring 1 was drilled at the proposed MSE wall site located about 400 feet to the southeast. The borings were advanced with 4 inch diameter continuous flight auger powered by a truck -mounted CME-45B drill rig. The borings were logged by a representative ofHepworth-Pawlak Geotechnical, Inc. Job No. 111 195A " lgtevch -3- Samples of the subsoils were taken with 1 % inch and 2 inch I.D. spoon samplers. The samplers were driven into the subsoils at various depths with blows from a 140 pound hammer falling 30 inches. This test is similar to the standard penetration test described by ASTM Method D-1586. The penetration resistance values are an indication of the relative density or consistency of the subsoils. Depths at which the samples were taken and the penetration resistance values are shown on the Logs of Exploratory Borings, Figure 2. The samples were returned to our laboratory for review by the project engineer and testing. SUBSURFACE CONDITIONS Graphic logs of the subsurface profiles encountered at the site are shown on Figure 2. The subsoils encountered, below minor gravel fill in Boring 2, consisted of medium dense to occasionally loose, typically clayey silty sand with gravel and cobbles that extended down to the drilled depths of 15 and 20 feet. The soils occasionally graded to slightly silty sandy gravel. Laboratory testing performed on samples obtained during the field exploration included natural moisture content and density, grain size analyses, and liquid and plastic limits. Results of swell -consolidation testing performed on a relatively undisturbed drive sample of the clayey silty sand soils presented on Figure 4, indicate low to moderate compressibility under conditions of loading and wetting. Results of gradation analyses performed on small diameter drive samples (minus 1 %z inch fraction) of the coarse granular subsoils are shown on Figure 5. The laboratory testing is summarized in Table 1. No free water was encountered in the borings at time of drilling. The subsoils were slightly moist to moist. Job No. 111 195A H�teCh -4- DESIGN RECOMMENDATIONS FOUNDATIONS Considering the subsurface conditions encountered in the exploratory borings and the nature of the proposed construction, we recommend the building be founded with spread footings bearing on the natural granular soils. _ The design and construction criteria presented below should be observed for a spread footing foundation system. 1) Footings placed on the undisturbed natural granular soils should be designed for an allowable bearing pressure of 2,000 psf. Based on experience, we expect settlement of footings designed and constructed as discussed in this section will be about 1 inch or less. _ 2) The footings should have a minimum width of 18 inches for continuous walls and 2 feet for isolated pads. 3) Exterior footings and footings beneath unheated areas should be provided with adequate soil cover above their bearing elevation for frost protection. Placement of foundations at least 48 inches below exterior grade is typically used in this area. 4) Continuous foundation walls should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 12 feet. Foundation walls acting as retaining structures should also be designed to resist a lateral earth pressure corresponding to an equivalent fluid unit weight of at least 50 pcf for the on -site soils as backfill. An underdrain should be provided behind retaining walls to prevent build-up of hydro -static pressures. 5) All existing fill, topsoil and any loose or disturbed soils should be removed and the footing bearing level extended down to the firm natural granular soils. The exposed soils in footing area should then be moistened and compacted. Job No. III 195A Ge tech _ 6) A representative of the geotechnical engineer should observe all footing r excavations prior to concrete placement to evaluate bearing conditions. FLOOR SLABS The natural on -site soils, exclusive of topsoil, are suitable to support lightly loaded slab - on -grade construction. To reduce the effects of some differential movement, floor slabs should be separated from all bearing walls and columns with expansion joints which allow unrestrained vertical movement. Floor slab control joints should be used to reduce damage due to shrinkage cracking. The requirements for joint spacing and slab reinforcement should be established by the designer based on experience and the intended - slab use. A minimum 4 inch layer of relatively well graded sand and gravel, such as road base, should be placed beneath slabs for subgrade support, This material should consist of minus 2 inch aggregate with at least 50% retained on the No. 4 sieve and less than 12% _ passing the No. 200 sieve. _ All fill materials for support of floor slabs should be compacted to at least 95% of maximum standard Proctor density at a moisture content near optimum. Required fill can consist of the on -site granular soils devoid of topsoil and oversized rocks, or a suitable granular material such as road base can be imported. SURFACE DRAINAGE w The following drainage precautions should be observed during construction and maintained at all times after the building has been completed: 1) Inundation of the foundation excavations and underslab areas should be avoided during construction. 2) Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95% of the maximum standard Proctor density in pavement and slab areas and to at least 90% of the maximum standard Proctor density in landscape areas. Job No. 111 195A Gg�tech -6- 3) The ground surface surrounding the exterior of the building should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 12 inches in the first 10 feet in unpaved areas and a minimum slope of 3 inches in the first 10 feet in paved areas. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. MSE WALL PARAMETERS The on -site granular soils appear suitable for support and backfill of the proposed mechanically stabilized earth (MSE) retaining wall. For the wall design, an angle of internal friction of 30 degrees, cohesion of zero and a moist unit weight of 125 pcf can be used for in -situ and compacted conditions. The plus 4 inch size rocks should be removed from the backfill. The backfill soils should be evaluated for standard properties and shear strength at the time of construction. _ Imported granular soils such as CDOT Class 1 structure backfill material are also suitable as the wail backfill. For CDOT Class 1 structure backfill material, an angle of internal friction of34 degrees, cohesion of zero and a moist unit weight of 130 pcf can be used for the wall design. The backfill should be compacted to at least 95% of the maximum standard Proctor density at a moisture content within about 2% of optimum. The backfill placement should be observed and tested for compaction tested on a regular basis.
