Site Description: The property is located south of Glenwood Springs, in the southwest portion of Spring Valley. Elevations range from 6400 to 7175 feet. The site is generally situated on the upland portion of a ridge that slopes from the north to the south to the Roaring Fork river valley approximately 800 ft, with slopes ranging from 4Yo to over 90o%. The steeper slopes have vegetation consisting primarily of pinior/juniper trees and sagebrush/grasses. The upland area consists of some fairly gentle rolling terrain, with slopes generally less than 10%. Portions of the upland area is existing agricultural lands. A vicinity map is shown on the enclosed plan map. B. Project Description: The applicant is requesting the amendment of the Preliminary Plan approved by Resolution No. 98-30. The proposed amendment adds a filing 64 to the previously approved Filings 6-10 of the Los Amigos PIID. The following table summarizes the changes: Type of Use Single Family Rural Residential Commercial Acres Open Space Acres Total Acreage Filings 6-10 164 4 0 975.93 1703.06 Filings 6.6.{-10 t74 4 4.56 936.47 171 1.68 The 4.6 ac. of land identified on the PUD plan aNeighborhood Commercial area was deleted from the previously approved Preliminary Plan due to it being identified as "presently non-developable", due to a lack of central sewer being available. The additional 10 dwelling units were deleted from the last application for the same reason, even though they were consistent with the approved PIID densities. AII of the lots will be served by the existing central water supply system that presently has 320,000 gallon storage tank. An additional storage tank will built on the west end of the project. The application notes that there will be fire flows ranging from 500 gpm to 1500 gpm for the project. All of the additional lots will be served by a low pressure central sewer system , except for the four nral lots which will utilize individual sewage disposal systems (ISDS). Primary access to the area will be from the extension of the existing private road, Los Amigos f)rive, and then there are seven shorter cul-de-sacs accessing a number of the proposed lots. Los Amigos drive will be extended almost three miles further back along the ridge. The cul-de-sacs and loop roads range in length just over 500 2 t, IIr. ft. to over 15,000 ft. in length.. There are proposed emergency access easements to adjoining fields, offof some of the longer cul-de-sacs and loops. REVIEW AGENCY COMMENTS 1. Division of Water Resources: The Division previously noted that the proposed water supply appears to be adequate, and rnjury to decreed water rights will not occur, as long as the water company operates pursuant to the decreed water rights and plan for XTWIXych are leased from the Los Amigos Ranch Partnership. (See letter -r* Colorado Department of Public Health and Environment: The department has verbally indicated that the development of a central sewer for the area is the preferable method treating sewage in the area. Roaring Fork School District RE-l: The District has previously determined that the proposed school site is adequate to meet the land requiremqnts for a school site, as opposed to paying cash in lieu of land.

Carbondale & Rural Fire Protection District: The District previously noted that portions of the development are in the Glenwood Springs Fire District and other areas are in no district. They recommend that the overlapping boundaries be resolved to allow the Carbondale District to protect the entire project and those portions not in any district be annexed to the District. They also recommended that the fire hydrant spacing be modified, which was agreed to by the developer's representative. The District in a previous letter noted that they will be requiring the developers to ?W#rfees directlv to the District, at the time of platting lots. (See letter pg. - 6. Bureau of Land Management: The BLM had expressed some concems about the potential for use conflicts between the public and private land.

Colorado State Forest Service: An agency representative previously went on site with a local fire department representative and the applicant's representative and concluded that the proposed development can be protected from wildfire. A number of recommendations were made in a prior letter regarding the site improvements, ridge line setbacks and construction materials for structures. Included with the letter were the NFPA 299 standards for the Protection of the Life and Prooerrv from ffi .f.il:'ff::t'#i'W%Trpreviouscommentsarest,lvarid'(See 8. Wright Water Engineers. lnc.: WWE was hired by the Cowrty to assist in the review of the Los Amigos Ranch Preliminary Plan. They noted a number of issues that needed to be resolved before the County approved the previous Preliminary Plan.. WWE reviewed the application for Filings 6-10 and noted a number of issues related to the lots removed from the previous application, the rural lots, drainage and the use :,T:l;,*ll;iff"f:;.",'"::t:i3::,:;:?#/ffzing'fhewwEresponse'[o MAJOR ISSUES AND CONCERNS Zonrng: The Los Amigos PIID zone district text and PUD Plan were amended by Resolution No. 96-34. As a condition of approval for the amendments, the applicant was required to dedicate at least the equivalent of 25%o of each subdivision to the Los Amigos homeowners association. Filings 6-10 is a total of 171 1.68 ac. in size, with 936.47 ac. (55%,) of Open Space. Filing 6 included lots that had been previously designated "presently non- developable single-family residential" and an area designated "presently non- developable neighborhood commercial". It would have been necessary to either merge the non-developable residential lots into some of the proposed lots or to amend the PUD to merge the lots with the Open Space. These lots have been added back into the development, as noted previously. The non-developable neighborhood commercial needs to be platted as separate lot in the first final plat. Comprehensive Plan Compliance: The 1995 Garfield County Comprehensive PIan identifies the Los Amigos PIID as an existing subdivision. and the PIID was found to be in general conformity with the Comprehensive Plan when it was amended in t996. Soils/Topography: The applicant's geologic report for this portion of the development "did not identifu any geologic conditions or potential geologic hazards that would prevent development of the site for the intended single family residential use. The Board of County Commissioners required that the following plat note be placed on all subsequent plats, as a part of the PIID amendment approved: A. B. C. 4 D. "Prior to the issuance of a building permit, the owner of each lot shall prepare and submit a soils and foundation report, a grading and drainage plan, and a geoiogically acceptable building site prepared and certified by a professional engineei. All improvements shall be constructed in accordance with such engineering recorlmendations, which shall be a condition of Los Amigos Ranch Architectural Control Committee approval and the building permit." WWE engineers noted in their letter, that RR Lot 3 appears to have a very limited building lot area, based upon the geologic report. After further discussion with the applicant, it was agreed that the final plat for RR Lot 3 will include a building envelope designated by registered professional geotechnical engineer and a plat note requiring the submittal of foundation design stamped by a professional geotechnical engineer with the building permit application. Road/Access: The proposed subdivision is accessed by Los Amigos Drive, which is being built to minor collector standards and will handle up to 250 single family dwellings. The applicants have proposed to build Los Amigos Drive as a minor collector with a 60 ft. row and l2 ft. driving lanes, up to Station 143+15.38. The rest of Los Amigos Drive will be built to Secondary Access standard with a 60 ft. ROW, with 11 ft. driving lanes. All other roads will be built to Rural Access standards with a 50 ft. ROW and 11 ft. wide driving lanes. All of the roads will have a chip and seal surface. All roads need to have names assigned to them, that are not used elsewhere in the County. Staffsuggests that the applicants not use "cedar" or "pinion" for any of the proposed streets names. Fire Protection: The Carbondale and Rural Fire Department reviewed the project and stated that the proposed amount of water appeared to be adequate and that the roads were adequately sized to accommodate emergency services equipment. The District had asked previously that the fire hydrant spacing be reduced to 500 ft. to comply with the Uniform Fire Code standards. The revised application was reviewed by the Fire District and hydrant spacing was agreed to by the developer. Any final plat application should include a letter from the District approving the hydrant spacing. It was also noted that a portion of the development is located in the Glenwood Springs Rural Fire Protection district and another portion in no district. The Glenwood Springs section is located on the north end of the development and is only accessible from CR 114, It has been proposed to deannex the portion of the in the Glenwood district and annex it to the Carbondale district. The non-district area is on the east side of the development. Both areas need to be annexed into the Carbondale Fire District. E. F.Water: As a part of the PUD amendment approval, the applicant was required to set forth the method of transferring the legal ownership and control oi tfr" water distribution facilities and water rights to the Los Amigos Homeowners Association. An agreement was submitted and approved by the Board of County Commissioners at the time of Final Plat approval of Filing 5 All new lots will have to be included in the same homeowners association. WWE has noted that RR Lots 1-4 are proposed to have individual wells for the source of domestic water. They expressed concern about the use of wells for RR Lots 1-3, given the history of wells in the area and the proposed use of ISDS by the lots above the lots. They recommend that the " developer help facilitate the shortest connection possible to the central water system with easements". Staffconcurs with the recommendation and would add that the issue needs to be resolved prior to the approval of a Preliminary Plan by the Board of county Commissioners. Wastewater: The previous application had all ofthe residential lots using individual sewage disposal systems (ISDS). As a condition of approval of the previous Preliminary Plan contained in Resolution No. 98-30, requiring that the "method of sewage disposal shall be a low pressure central sewage disposal system of a type similar to that proposed by the Garfield County engineer,...,, The application includes such a system. Road Impacts: The applicant was required to make certain improvements to the intersection of the subdivision's main entrance and County Road 114 and to pay a road impact fee at the time of final plat. The impact fee is to be based on the most current analysis of the cost of improvements to 114 from the Auburn Ridge apartments road intersection to Highway 82 and an analysis of the proportionate share of those expenses attributed to the Los Amigos PLID for those road improvements. The only study available dealing with those specific parameters, is the analysis submitted by the applicant's engineer at the ptrD approval. The subsequent analysis done by the County used a different basis for establishing and cannot be used to establish a road impact fee for this P[ID. The PIID approval established a $2OOilot road impact fee for this development. Drainage: WWE noted that the application had noted some minor increase the amount of surface nrnofffrom the project, but had not proposed any mitigation for the increases. The applicants have reviewed the issue again and recommended on site detention of the surface runoffin certain drainages. There is no calculation of the amount of detention area is required, based upon calculations. The subdivision regulations require the calculation of the runoffand inclusion of the calculations in G. F. G. 6 a the application. WWE had noted that the proposed locations appear to be correct, but there is a need for the calculations prior to the submittal of a final plat. Additional calculations were submitted by the applicant and found to be acceptable by WWE. PUD Requirements : The applicant was required to include the following plat notes on any final plat: Prior to the issuance of a building permit, the owner of each lot shall prepare and submit a soils and fourdation report, a grading and drainage plan, and a geologically acceptable building site prepared and certified by a professional engineer. All improvements shall be constructed in accordance with such engineering recommendations, which shall be a condition of Los Amigos Ranch Architectural control committee approval and the building permit. The owner of each lot utilizing an individual sewage disposal system (ISDS) shall obtain site specific percolation tests to determine whether a standard septic system is acceptable or an engineered system is appropriate or required. Each ISDS shall be designed to minimize tree removal and changes to the natural contours of the land. 3. The recommendations of the Colorado State Forester and the Fire Chief as set forth in the Supplemental Declarations dated September 28,1992 et. seq shall be followed in the construction of all structures. All lots designated to lie within the Spring Valley Sanitation District shall obtain central sewer service pursuant to agreement with the District. Open hearlh solid-fuel burning fueplaces are not allowed. Each dwelling unit is allowed one dog. uI.RECOMMENDED FINDINGS: That the proper publication, public notice and posting were provided as required by law for the hearing before the Planning Commission; and That the hearing before the Planning Commission was extensive and complete, that all pertinent facts, matters and issues were submitted and that alt interested parties were heard at that hearing; and G. 1. 2. 4. 5. 6.
