SITE DATA: 28.571 acres WATER: Mid -Valley Metro District SEWER: Mid -Valley Metro District ACCESS: Improved Access from New SH 82 EXISTING ZONING: R/L/SD and R/G/UD ADJACENT ZONING: North - A/R/RD South - A/R/RD East - A/R/RD West - (Blue Lake) I_ RELATIONSHIP TO THE COMPREHENSIVE PLAN The tract of land is located in District C, Rural Areas, Minor Environmental Constraints and District D, Rural Areas, Moderate Environmental Constraints. II_ DESCRIPTION OF THE PROPOSAL A. Site Description: The subject parcel is primarily historic agricultural land, which has been divided by the State Highway 82 right-of-way. The current alignment of SH 82 has created two geographically separate parcels: an 11.761 acre parcel on the south side of the new four -lane; and a 28.331 acre parcel to the north of the new four -lane. The 28.331 acre parcel is the subject of the Preliminary Plan. The parcel slopes gently to the north, and is bisected by Blue Creek. An existing dwelling is located in the northeast corner of the site, beyond the Eagle County Line. A vicinity map is included in the Preliminary Plan packet (attached). rz/(2C 01 —1-0 rz_li-isp 2-0,000 1 B. Request. The applicant are proposing a total of 64 dwelling units on the property. The proposed land use mix is shown on Table 1.

Since the time of preliminary plan submittal, the applicant has had a formal wetlands delination, and the location of wetlands has modified the plan somewhat. Staff and the applicant will present the modifications at the public hearing. III. REVIEW AGENCY COMMENTS A. Colorado Geologic Survey. The Colorado Geologic Survey has reviewed the project at sketch plan, and had the following comments (see letter on pages ): CR1-1 Mi A 1. The only serious geologic constraint to the project is the possibility of sinkhole development caused by collapse of underground voids in the Eagle Valley Evaporite Formation. The Geologic Survey recommends a shallow geophysical survey to locate any voids on the property. 2. Lots 8 through 14 (single-family along hillside) may have adverse drainage impacts due to the adjacent slope. Recommendations include drainage engineering prior to siting structures. 3. During higher runoff years, the flatter portions of the parcel may experience water rising above normal foundation depths. Recommendations included that no basements or crawl spaces be allowed under the proposed townhomes. Chen -Northern conducted a subsurface investigation of the site, and concluded the following (see geotech report in Preliminary Plan packet): 1. No sinkholes are evident on the site, and the risk of future ground subsidence is "relatively low"; 2 • • 2. The potential for debris flow does not appear to constrain the development of the northern (hillside) lots, although staff confirmed with Chen -Northern that a final analysis has not been completed. Stan Helenschmidt (Chen -Northern) indicated that a final report regarding debris flow hazards should be completed prior to the hearing before the Planning Commission; 3. Due the high permeability of the soil and the high groundwater levels in the flatter portions of the site, it is recommended that full basements not be considered. Staff submitted the Chen -Northern report for CGS survey review, and James Soule's June 9th, 1994 letter is attached on pages el' �O . Concern on the part of CGS staff still include the risk of surface ground failure due to the collapse of Eagle Valley Evaporate underlying the project. B. Colorado Department of Health. Dwain Watson has reviewed the project, and has endorsed the proposed tie-in to the Metro District (see letter on page ). C. Colorado Division of Wildlife. Randy Cote from the Division of Wildlife previously commented on the project during the sketch plan phase, and suggested that dog restrictions be considered during the approval process. D. Mid -Valley Metro District. Lee Leavenworth, attorney for the Metro District has reviewed the Preliminary Plan, and had the following comments: 1. A raw water irrigation plan has not been submitted to the District, and should be a condition of approval prior to Final Plat. 2. The covenants must be amended to reflect agreements consistent with the raw water irrigation plan. Staff suggests that this also be considered a condition of approval. 3. A landscape plan must also be submitted, consistent with the Pre - Inclusion Agreement. 4. A line extension agreement must also be executed prior to the Final Plat. A copy of Mr. Leavenworth's May 17, 1994 letter is attached on pages 11,17---. E. Eagle County. Eagle County has reviewed the project, and Paul Clarkson's May 18th, 1994 letter is attached on page 13 . In short, the applicant is currently pursuing 1041 approval to allow for the expansion of the Metro District facilities. Phone conversations with the County indicate that approval is expected by the Eagle County Commissioners. IV. STAFF COMMENTS A. Soils/Topograp4: Chen -Northern has recommended mitigation of all issues regarding geological constraints on the property. 3 • • B. Roads/Access: As proposed, the project would utilize a single point of access from State Highway 82. Improvements associated with the widening of SH 82 included the construction of access/egress lanes and a left-hand turn pocket, at the applicant's expense, from the entrance of the project. Rich Persky, District Engineer for the Colorado Department of Transportation, indicated by phone that all access issues have been addressed the permitting process undertaken at the time the additional lanes were established. Garfield County Road standards (Section 9.35) use a sliding scale to determine Right -of -Way requirements and lane widths. For projects proposing units between 40 and 250 units, a 60' ROW with 12' lanes. As shown on the Preliminary Plan, both Arnold Loop and Arnold Drive are proposed with 50' ROW with 11' lanes. This configuration is not consistent with the standards described in Section 9.35, and no variance procedure is currently in place to reduce ROW or lane width requirements. The Board of County Commissioners has in the past allowed for a reduction in ROW and land width requirements if the expected traffic load of a particular portion of a subdivision road is less than the total number of dwelling units associated with the project. For example, if a road "tapers" into accessing fewer dwelling units, a specific section of road can be reduced to the appropriate template design for that particular roadway segment. Staff suggests that the applicant address this issue at the Preliminary Plan hearing before the Planning Commission. C. Fire Protection: No letter of approval has been submitted from the appropriate fire district. Staff suggests that this be a condition or approval, and be obtained prior to the public hearing before the Board of County Commissioners. D. Lot Design: The lot design is identical to the configuration presented to the Planning Commission during the rezoning and sketch plan review. Staff notes that each multi -family lot, as shown on Sheet 3, would preclude separate title to each unit, but would allow conveyance of individual 4 and 5 -unit buildings. If the applicant intends on conveying title to each multi -family unit, each separate lot would have to appear on the final plat. In addition, variances would have to be requested to allow a zero lot -line setback. A solution to the same issue was handled in the following fashion for the Aspen Glen multi -family lots: 1. A plat note would be used to confirm that the developer reserves the right to request subsequent subdivision for the multi -family lots at a future date, without returning to a Preliminary Plan hearing. 2. Following the construction of the foundation for the multi -family lots, a surveyor would "shoot in" the common walls for each unit. 3. A variance request, requiring Board of Adjustment Approval and a public hearing, would be made for all lots requiring encroachment into the required side yard setback. This would not be necessary if the applicant had pursued a PUD. 4 • 4. Each lot containing multi -family units would then be amended ("Amended Final Plat for Lots A, B, etc...") to reflect the re -subdivision. In concept, staff supports the development as a high-quality residential development that includes a mix of housing types, ample open space, significant protection of the integrity of Blue Creek, and integrated recreational opportunities with the adjacent Blue Lake project. In addition, the site presents significant opportunities for solar access (four of the nine multi -family pods have southern exposure). E. Comprehensive Plan Compliance. During the rezoning and sketch plan processes, significant discussion centered on Comprehensive Plan compliance. In short, -high-density residential projects were never envisioned for the site. Staff notes that current zoning and the 1984 Comprehensive Plan did not consider the possibility of extending Mid -Valley Metro District infrastructure into Garfield County. In staff's opinion, the approval of the service district expansion reflects a change in circumstance, and the project is in substantial compliance with the Comprehensive Plan. F. Potential Wetlands Impacts. The applicant proposes to modify the Blue Creek drainage similar to the channel improvements associated with the adjacent Blue Lake filings. These improvements are necessary to ensure that Blue Creek is capable of handling 100 -year flood waters within the channel. Some wetland impacts are unavoidable, and may require a Nationwide Permit from the Army Corps of Engineers. To date, no documentation has been received from the Corps. Staff suggests Corps of Engineers approval be a condition of approval. IV. Recommendation On June 14, 1994, the Planning Commission recommended approval, subject to the following conditions: 1. All representations of the applicant, either within the application or stated at the public hearing with the Planning Commission, be considered conditions of approval. 2. The applicants shall establish a Homeowners Association and shall be incorporated in accordance with the requirements of Colorado Revised Statutes. The Homeowner's Association shall be responsible for all requirements and agreements associated with the Mid -Valley District, road maintenance and snow removal. The articles of incorporation and restrictive covenants shall be reviewed by County Staff prior to the approval of a Final Plat. 3. The applicants shall prepare and submit a Subdivision Improvements Agreement, addressing all improvements, prior to recording a final plat. 4. The applicants shall submit improvement plans for all road, drainage and utility improvements prior to the approval of a final plat. 5. All utilities shall be placed underground. 5 • 6. All cut slopes created during construction shall be revegetated with native grasses using certified weed -free seed. 7. The applicants shall pay $200 per lot in school impact fees prior to approval of the final plat. 8. All roadways shall be designed and constructed in conformance with design standards set forth in the Subdivision Regulations and in place at the time of final plat. All construction shall be consistent with the recommendations of the applicant's geologist, described in "Summary Report of Geotechnical Conditions and Preliminary Recommendations", dated April 18, 1994 by Chen Northern, Inc. All recommendations made by Chen -Northern steal also be followed. 10. If the applicant intends on resubdividing the multi -family lots, provisions (i.e. plat note) shall be made at the time of Preliminary Plan approval, and subsequent variances and amended plats shall be submitted and approved consistent with Garfield County zoning and subdivision regulations in affect at that time. 11. All requirements associated with agreements with the Mid -Valley Metro District, described in a May 17, 1994er from Lee Leavenworth, are considered conditions of approval.

El Jebel Dear Mr. Michaelson: At your request and in accordance with S.B. 35 (1972), we have reviewed the materials submitted for and made a field inspection on February 14, 1994, of the site of the proposed residential subdivision indicated alcove. At the tine of site visit, there was show cover over much of the parcel and so some of our comments are based on prior experiences in the area. The following comments summarize our findings. (1) The only serious geologic constraint to development of this parcel as planned is the possibility of ground lowering (sinkhole development) caused by collapse of underground voids in the Eagle Valley Evaporite [Formation] which underlies the older alluvial gravels of the Roaring Fork River and younger gravels of Blue Creek. 'These gravels are found at the surface over most. of the parcel, Otherwise, these gravels present. few serious foundation - engineering or other geologic problems, except as noted in (3), fur this or any other typical residential development. Because of this possibility, we recommend that the proponent have a shallow geophysical survey made to determine if any such voids are present:! You will recall that WC have made similar recommendations in the past for ether similar wets and subdivision proposals where the Eagle Valley Formation is at or near the surface. (2) The overall drainage across the parcel is excellent except for places iimnediately. .adjacent to the steeper slopes on il.s north side. It will be advisable for the developer and/or lot purchasers of lots 8 to 14 (in Garfield County) to have a drainage engincell evaluate drainage across these lots before siting buildings and other improvements, • (3) It is possible that during wetter years or spring snowrnel1 runoff times that the water table in the lower flatter parts of this parcel could rise above normal foundation depths for structures with basements.

In addition, 1 visited the site again as previously there was significant snow cover which made all but very generalized field study of the area impossible. The following comments summarize our findings. (1) Our most serious geology -related concern about development of this parcel as planned remains the possibility of surface ground failure caused by collapse of underground solution cavities, Le, sinkhole formation, The newly submitted Summary Report of Ceotechnical Conditions and Preliminary Recommendations prepared by Chen Northern, Inc., and dated April 18, 1994, indicates that, "Sinkholes were not noted in the area of the proposed development. The exploratory borings [12 in number] did not penetrate the bedrock and an evaluation of sinkhole -related subsidence potential is beyond the scope of this investigation_ In our opinion, the risk of ground subsidence within the development is relatively low.". Our chief concern about these continents and their validity insofar as related potential hazards for this development, as currently proposed, is that there is no standard for potential hazards indicated in the Chen Northern statement and, as a result, their value of "relatively low" is therefore meaningless. Their final statement in the same paragraph indicates that they can evaluate this hazard if their client (Isom and Associates) desires to do so. Our opinion is that this hazard should be evaluated by valid geotechnical and/or geophysical methods prior to approval of this subdivision proposal and appropriate hazard -mitigation measures if any are deemed to he needed or possible should be indicated in the consultant's (Chen Northern or another) report.

I have the following continents: 1. Article X1 of the Rules and Regulations of the District require the submission of a raw water irrigation plan. A copy of these regulations is enclosed. Paragraph 12 of the Pre- Inclusion'Agreement, a copy of which is enclosed, requires compliance with Article XI as part of the preliminary plat submittal to both Eagle and Garfield Counties. Therefore, the developers need to comply with this provision as soon as possible, although I do not believe it is necessary to hold up the processing of the preliminary plat. The District would like any preliminary plat approval to be contingent upon submission to the District, and approval by the District, of a raw water irrigation plan as required by Article XI and by the Pre -Inclusion Agreement. 2. The District will also require extensive covenants, of which the District is the third -party beneficiary, to ensure that the raw water irrigation plan that is adopted, and provides the basis for reduction in tap fees, is enforceable by the District and enforced as the primary enforcement entity by the property owners association. The covenants submitted as part of this package are not adequate for the District's purposes. 3. The Pre -Inclusion Agreement also provides for certain landscaping to occur at the developer's expense, as more fully set forth in paragraph 17. This landscape plan also should be submitted simultaneously with the raw water irrigation plan. 4. Finally, prior to final plat, the District will require the execution of a line extension agreement concerning utility construction. IF: \FILES \MICI IASL.1 ur -11 • LEAVENWORTII & CALOIA, P.C.

You have been referred a copy of the Preliminary Plan and should receive it shortly. You should know, however, that the Preliminary Plan cannot be heard by the Board until the "1041" application has been heard. Typically, they are presented concurrently. however, the "1041" application cannot be presented to the Board until at least 30 days after the Permit Authority has been determined it to be complete. Until such determination has been made, we are unable to schedule these 2 files for hearing before the Uoard. You will be referred a copy of the application when the Authority finds it complete.

These centers should be separated by open space to enhance community identity. (2) To reduce development density outside of community centers in a way which minimizes visual and physical impacts on the scenic and agricultural lands that characterize Eagle County. Locating urban density residential and commercial development in areas that are not in community centers promotes the "stripping out" of the Roaring Fork Valley. The extension of infrastructure facilities when such facilities are already available elsewhere also promotes further "sprawl".

MID VALLEY COMMUNITY PLAN This site is identified for potential low density residential. This designation is similar to that of the Resource Zone District. Therefore, the recommended allowance for the 16+ acres in Eagle County would be 1 dwelling unit. 2. 1041 The application includes statements that the Mid Valley Metropolitan District will provide water and sewer services. Such extensions will be subject to the "Guidelines and Regulations for Areas and Activities of State Interest of the County of Eagle, State of Colorado." It has been the policy of the County that such applications can only be considered prior to or during the Preliminary Plan process. This is the "1041" process as designated in Section 6.04 of the Eagle County Land Use Regulations, "Major Extensions of Existing Domestic Water and Sewage Treatment Systems." 3. Zoning Potential The Residential Suburban Low Density Zone designation could conceivably allow for up to 47 dwelling units on the 16+ acre site. Staff would suggest that the file continue as a PUD for the 9 single family lots. 4. Garfield County It is difficult to consider the proposed 9 lots without also considering the proposed development in Garfield County. The Mid Valley Community Master Plan recommends against this proposal but that Plan does not consider the development potential in the neighboring county. It is probably not good planning practice to strictly adhere to the Community Plan in spite of all that may be going on around the site. Therefore, Staff feels that 9 single family lots and open space is appropriate if and only if the Arnold proposal in Garfield County receives approval. The residential zone change proposal was heard and approved by the Garfield County Board of County Commissioners on March 14. 5. Mid Valley Treatment Ponds The proposed development is within a few hundred feet of the existing sewage treatment ponds. The possibility of odor complaints is high. The pre -inclusion agreement between the developer and Mid Valley contains language concerning the potential of this issue. Language to the same effect should be included in the covenants and final plats. Increasing the amount of platted private open space would increase the buffer from any future expansions of the treatment ponds. Platted building envelopes towards the north end of lots 7, 8 and 9 would have the same effect. 3 • • Eagle County Board of County Commissioners SU -318-94-S / ZC-259-94, Arnold Meadows March 29, 1994 6. Open Space Connection The possibility of connecting the open space improvements of Arnold Meadows and Blue Lake along Blue Creek is high. Staff would request that this possibility be thoroughly investigated. Connecting these amenities would create a "sum greater than the parts". 7. Parcel Ownership The Eagle County Surveyor has indicated that the 16.355 acre parcel is actually 2 separate parcels with two separate owners: Arnold and Nagel. The Nagle property was recently bought by Don Byers who has been behind the development proposal, however, the applicants are Robert and Gloria Arnold. This issue needs clarification. 8. Eagle County Engineer An Intergovernmental Agreement (IGA) should be entered into between Eagle and Garfield Counties for infrastructure maintenance by Garfield County. The reasoning is that the only way to enter the subdivision is through Garfield County. This, of course, will be unnecessary should the infrastructure be private. An extensive and detailed geologic and engineering investigation should be performed. Also, the school district should be consulted concerning school bus circulation. 9. Colorado Geological Survey (1) There are some concerns for sinkhole development. A shallow geophysical survey should be made. (2) Drainage appears to be good except for places immediately adjacent to the steeper slopes on the north side of the development. A drainage engineer should evaluate the drainage on these lots before siting buildings and other improvements. 10. Colorado State Forest Service The proposed subdivision's wildfire hazard rating is "low" and "moderate." The proposed mitigation is sufficient for the "low" rating. Further mitigation as outlined in the letter from John Grieve, dated 2/22/94, will be required for those lots rated "moderate". 11. Mt. Sopris Soil Conservation District (1) Any cuts for roads or constructions should be revegetated. (2) Weed free seed and mulch should be used and monitored. (3) Need for dog control in the covenants. (4) Concern for proper maintenance and protection of irrigation ditch. (5) Concern for continued use of irrigation water rights. 12. Irrigation Ditch It is felt that an irrigation ditch bisecting platted property is inappropriate. It interferes with proper maintenance and restricts the buildability of the parcel. Such ditches should be along property lines and in designated easements. 4 Eagle County Board of County Commissioners SU -318-94-S / ZC-259-94, Arnold Meadows March 29, 1994 VI. FINDINGS: Pursuant to Section 2.14.04(1) of the Eagle County Land Use Regulations (Zone District Amendment): a) The rezoning is not consistent with the Master Plan, however, the area in question possesses the geological, physical and other environmental conditions compatible with the characteristics of the use requested. The advantages of the use do not outweigh the disadvantages: b) Conceptual evidence exists that the land has access and can be serviced with water and sewage disposal systems, however, it has not been demonstrated that it is appropriate with the zone district being sought; c) 1) The area for which rezoning is requested has not changed or is not changing to such a degree that it is in the public interest to encourage a new use or density in the area; or 2) The proposed rezoning is not necessary in order to provide land for a demonstrated need. Pursuant to Section 2.17.02(3) of the Eagle County Land Use Regulations (Sketch Plan Review), the following have been considered: a) Conformance with the Master Plan, policies, guidelines, zoning and other applicable regulations; b) Suitability of the land for subdivision; c) Comments and recommendations from the agencies listed in Section 2.17.02(1); d) Evidence that the parcel of land proposed for subdivision has access to the state highway system capable of servicing the development. VII. STAFF RECOMMENDATION: Zone District Amendment: Denial Sketch Plan: Approval 1. The proposal shall proceed to the Preliminary Stage as a Planned Unit Development for 9 single family units; 2. A "1041" application shall be submitted with the Preliminary Plan for concurrent review if it is determined to be required; 3. Language similar to the pre -inclusion agreement between the developer and Mid Valley shall be included in the covenants and final plats concerning the close proximity to the sewage treatment ponds. Either the amount of platted private open space should be increased or building envelopes should be platted towards the north end of lots 7, 8 and 9 in order to increase the buffer from the treatment ponds; 5 • • Eagle County Board of County Commissioners SU -318-94-S / ZC-259-94, Arnold Meadows March 29, 1994 4. The applicant shall investigate with the Blue Lake Homeowners Association the possibility of connecting their respective open spaces; 5. If any infrastructure maintenance is required that would ordinarily be provided by the County, an IGA should be facilitated by the applicant and between the two counties for such maintenance to be provided by Garfield County; 6. An extensive and detailed geologic and engineering investigation should be performed particularly on the lots immediately adjacent to the steeper slopes on the north side of the development. Drainage on these lots should also be evaluated; 7. The Colorado State Forest Service and the Mt. Sopris Soil Conservation District concerns should be addressed in the covenants and/or the PUD Control Document; 8. The lots should be reconfigured or the ditch realigned so that no lot is being bisected by the ditch. A ditch easement agreement should be arrived at between the applicant and the ditch owners. If the ditch is piped underground, then every effort should be made to position the pipe so that a minimum of public infrastructure is disturbed should the pipe need repair. 9. The school district and RFTA should be consulted concerning internal circulation and bus stops. VIII. APPLICANT RESPONSE: IX. PUBLIC COMMENT: At their Public Meeting of March 17, 1994, the Roaring Fork Planning Commission unanimously recommended approval incorporating the findings and the Staff recommended conditions adding the language, "If the ditch is piped underground, then every effort should be made to position the pipe so that a minimum of public infrastructure is disturbed should the pipe need repair." to condition No. 8. 6 COMMUNITY DEVLOPMENT DEPARTMENT (303) 328-8730 EAGLE COUNTY, COLORADO Dave Michaelson Garfield County Planning Department 109 8th Street Glenwood Springs, CO 81603-3303 RE: Arnold Meadows Dear Dave: 500 BROADWAY P.O. BOX 179 EAGLE. COLORADO 81631 FAX (303) 328-7185 February 10, 1994 Thank you for the opportunity to comment further on the above reference proposal. We would like take this opportunity to reiterate our comments and concerns in the December 30, 1993 letter to your office concerning the application to re -zone the site. The Mid Valley Community Master Plan recommends that development of urban and suburban densities proceed down valley no further than Blue Lake. However, it appears that the project has reached a level of approval and we would therefore, like to make these additional comments: 1. We think that it would be appropriate to ask the developer to contact the Blue Lake Homeowner's Association about the possibility of connecting their respective private open spaces. I believe that Blue Lake is proposing a path along Blue Creek and around Blue Lake. Connecting these amenities would create a "sum greater than the parts." 2. As you know, Eagle County is considering the development of some 16 acres of Arnold property between the Garfield County line and Blue Lake. The Mid Valley Community Master Plan recommends that this area remain in very low density residential development. Staff recognizes that continuing to restrict the development of this 16 acre site in light of urban densities on either side is tantamount to ignoring reality. Therefore, it is likely that Staff will be recommending approval of that portion of Arnold Meadows in Eagle County should the development in Garfield County proceed to the next step of approval. However, you should know that if the roads are proposed to be public, it is likely that Eagle County will be requiring the developer to facilitate an Intergovernmental Agreement (IGA) between the two • • afield County Planning Department ebruary 10, 1994 Page 2 counties concerning the maintenance of the roads. Indications from the Eagle County Engineering Department as well as Road and Bridge are that Eagle County should not be responsible for any such maintenance. This will probably be a condition of approval for that portion in Eagle County. For your information, the application received by this office is for a combined zone change and sketch plan. The zone change request is for Residential Suburban Low Density (RSL) which is a 15,000 sq. ft. minimum lot size. We will be recommending that the file proceed under a PUD approach for 9 units since it is conceivable that such RSL zoning will allow for up to 46 units. This would be entirely unacceptable. 3. Eagle County has adopted regulations pursuant to HB 1041 which govern major extensions of existing domestic water and sewage treatment systems. The Mid Valley Metropolitan District will be required to partake in this process. A new service plan will also be required. We do this to insure that anticipated growth and development that may occur as a result of such major extensions can be accommodated within the financial and environmental capacity of the new and source development areas to sustain such growth and development. It is also another tool by which the planned and orderly development of land can be insured. 4. We also feel that you may want to refer this file to the Colorado Geological Survey and the local Soil Conservation District (Mt. Sopris?). Blue Lake has experienced some debris sliding along the steeper slopes and while we have not yet experienced it, there has been some expressed concerns for sinkhole development. Additionally, there have been some problems concerning a high ground water table during the irrigation season. The fifth and final filing of Blue Lake has been required to take certain measures to mitigate the numerous wet basements and crawl spaces in Filing 4. The proximity of Blue Creek and the Cerise and Arnold Ditch will likely cause similar difficulties in Arnold Meadows. Again, thank you for the opportunity to comment. We look forward to continued cooperation with Garfield County. Sincerely, Paul E.

The Engineering and Community Development Departments recently discussed it and have the following comments: 1. Locating urban density residential and commercial development in areas that are not in community and commercial centers promotes the "stripping out" of the Roaring Fork Valley. New development of urban and suburban densities and uses should be directed to existing community centers that are separated by open space which enhances community identity. Encouraging development of higher densities and more intense uses outside of the community centers increases the visual and physical impacts on the scenic and agricultural lands that characterize the Valley. The Roaring Fork Valley has been coming under an increasing amount of development pressure over the years. It is becoming increasingly important that critical buffer areas between community centers remain primarily in their natural state. This proposal only increases the threat to the open rural character of the Valley. 2. The intent of the CDOT was to convert the old Hwy 82 into a local street accessing the existing homes in this area. The road was also intended to function as a bikeway. Encouraging commercial type uses on this road will increase the truck and passenger vehicle traffic and ultimately have the effect of defeating the purpose of building the four - lane highway in the first place. J • • Garfield County Planning Department December 30, 1993 Page 2 3. The application does not state whether or not direct access to the C/L will be provided from the new 4 -lane. The intersection of the new Highway 82 and the old Valley Road (at Blue Lake) has an extremely short stacking distance and is considered by the Eagle County Engineering Dept. to be entirely inadequate as a commercial access point. The above comments are developed from and are based upon philosophies, goals, objectives and policies of the various Eagle County Master Plans utilized by staff in the review of local development proposals. If you should desire further clarification, please contact any planner on staff at Eagle County. Sincerely, Paul E. Clarkson AICP Planner cc: Keith Montag Sid Fox
