Property Description The Lake Springs Ranch Planned Unit Development is located approximately 3.5 miles southeast of the City of Glenwood Springs off of CR 114. The 459.38-acre subdivision is divided by CR 1 14 and the portion west of CR 114 is further divided by County Road 119 (CR 119). The western portion of the property consists of the Applicant's residence and the Rivendell Sod Farm. The eastern portion of the property contains one unoccupied rustic cabin and a two-story log cabin located near a large pond. The subdivision will obtain potable water from two wells located on the eastern portion of the site. The property has a variety of site constraints including: wetlands, several ponds, geologic fault, a rare plant species, high value wildlife winter range, evaporite deformation, Steep topography, and utility easements (electric, effluent and gravity sewer lines). Iigure 1 Vicinity lllap tlPage Lake SPrings Ranch Board of County Commissioners April 11,2016 B. History: The Lake Sprihgs Ranch PUD was originally approved in June '1979 and subsequently amended to allow for ZiZ units located within three zone districts: Residential/Single-Family District (R/SF); Residential/Cluster Housing District (R/CH); and, Agriculture/Open Space District (A/OS). A Preliminary Plan was approved in 1984 however it appears that the valid preliminary plan associated with the subdivision was approved in 2002, Resolution 02-109. A PUD Amendment was approved in 2004 which amended the phasing plan to decrease the number of lots to be included in the first final plat, and the final plat was approved in 2004Ior 21 lots and Agricultural Preserve on 1 18.S-acres. Since 2004 the Applicant has recorded a series of conservation easements, held by Aspen Valley Land Trust (AVLT), that cover approximately 143.08 acres of the property located on west of CR 114, as indicated on the map below. The conservation easements are dedicated in perpetuity and AVLT agrees to preserve and protect the land due to its natural, scenic, agricultural, historical and open space resources. The remaining number of units in Lake Springs Ranch is 1 36 units (1 18 f ree- market units and 18 affordable units). PUD and Preliminary Plan Amendments were approved in 2012 by the County in Resolution 2012- 80. These approvals added land to the PUD as well exchanged land with adjacent property owners, increased the number of affordable housing units pursuant to the requirements of the Unified Land Use Resolution of 2008, as amended (in effect at the time of the application), as well as revisions to the subdivision layout. 2lPag,r c. 1. Lake Springs Ranch Board of CountY Commissioners April 11, 2016 PfOpOSal: Application materials include original submittal documents and supplements in Exhibit Q Preliminarv Plan Amendment The Applicant seeks to amend the Preliminary Plan as follows: a. Amend the drainage plan to utilize more of the valley floor for temporary stormwater storage in order to minimize impacts on conserved land; b. Eliminate Conditionl5 of Resolution 2012-80 since the stormwater impoundment will not be necessary according to the revised drainage analysis; c. Redesign lots 8, 9, 1 1 and 13 of Filing 2 to allow cul-de-sacs to be removed f rom conserved areas; d. Revise the language of Condition 14 of Resolution 2012-80 to clarify that the central water system must be reviewed under the CDPHE regulations for "community" water systems; e. Amend the Preliminary Plan and Phasing Plan to show the unplatted portions of conserved lands, those lands located outside of final plat of Filing 1, as "Conserved Lands" and to eliminate the lot lines currently indicated on the approved Preliminary Plan. This is necessary for the future final plat to remain consistent with the Preliminary Plan. Materials to support this request are located in Supplemental lnformation, Exhibit Q. PUD Amendment a. Redesign Lots 8,9, 11 and 13 of Filing 2 to allow cul-de-sacs to be removed from conserved areas; b. Amend the Phasing Plan: i. To move required improvements to CR 1 14 from Phase 2 to Phase 3; ii. Shift I lots from Phase 4 to Phase 3; and iii. Remove those approved lots located in what is now conserved lands area. Materials to support this request are located in Supplemental lnformation, Exhibit Q. c. Decrease the required affordable housing to be provided by the development from 15% as required under the Unified Land Use Resolution of 2008, as amended to the 10% currently required under the 2013 Land Use and Development Code, as amended. ^MEIGOPtrt!'MIN^KY PUN LAKE SPRINGS RANCH P.U.D.elllff-a .a- #I il I tg;#l I Lf"o-- , Figurr:3 - ProposuiPreliminary Plan 2. 3lPagc , 1*,"-_\.".._li\* f[1ry,gryftxfFlt q.k ---r imlt \="- ,V.1.ffffi6#, 1 ASr+{I\v- $ I \#; :,ffi t Lake Springs Ranch Board of CountY Commissioners April 1'1, 2016 Zone Map Amendment The Applicant seeks to correct the Garfield County Zoning Map to reflect property exchanges with adjacent owners - these changes were approved in prior PUD amendments but not identified on the zoning map.

Mountain Cross Enqineerinq, Exhibit G, L and P: Chris Hale responded primarily regarding the request to eliminate stormwater detention and drainage issues related to CR 114. Mr. Hale met with the Applicant's engineer and requested "evidence that the detention volume from the previously approved application is provided and that the flows are restricted to the J. 2. 41 a*x.I i J} ,"Itt I Lake SPrings Ranch Board of County Commissioners April 11,2016 pre-project levels in the meadow per the LUDC." The drainage plan was revised by the Applicant to include detention on the west side of CR 114 and engineering issues were resolved. 3. Environmental Health, Exhibit l: Environmental Health provided information regardlng the distinction between the different types of water systems defined by CDPHE. No response was received from the following agencies: Gariield County Housing Authority Garfield County Vegetation Manager Colorado Department of Transportation Colorado Department of Public Health and Environment Carbondale & Rural Fire Protection District Aspen Valley Land Trust (AVLT) A request to amend an approved Preliminary Plan and PUD commences with a determination on whether the proposed amendments are considered Minor or Substantial Modifications. A determination has been made that the requested amendments to Lake Spring Ranch are substantial in nature, particularly due to the request to amend conditions of approval and to request a decrease the amount of affordable housing provided by the development. A substantial modification requires a recommendation by the Planning Commission with a decision issued by the Board of County Commissioners. The reviews of these applications are subject to the criteria contained in Article 7 - Standards, Section 4-113 Rezoning, and Section 6-401 PUD Standards of the LUDC Review of amendment applications is limited to those areas requested to be amended, therefore a significant portion of the review criteria are not applicable to these requests. Staff has included significant discussion only related to those standards that will be impacted by the proposed amendments. DIVISION 1 GENERAL APPROVAL STANDARDS FOR LAND USE CHANGE PERMITS Section 7-101 Zone District Use Regulations Staff Response: This subdivision was zoned PUD in 1979. These applications include a proposal to amend the existing PUD zoning consistent with the Preliminary Plan Amendments requested. Section 7-102 Comprehensive Plan and lntergovernmental Agreements Staff Response: The proposed amendments do not appear to affect general conformity of the project with the Garfield County Comprehensive Plan 2030. Section 7-1 03 Compatibility Staff Response: The proposal does not affect the compatibility of the Lake Springs Ranch with the adjacent properties including Spring Valley Ranch PUD to the north and Elk Springs PUD to the southwest. Section 7-104 Source of Water Staff Response: The proposal does not affect the currently approved provision of a central water system to serve the development. 5ll'agc Lake Springs Ranch Board of County Commissioners April 11,2016 Section 7-105 CentralWater Distribution and Wastewater Systems Staff Response: The proposal does not affect the fact that the subdivision has been approved with a central water system, and sanitation will be provided by Spring Valley Sanitation District (SVSD). Section 7-106 Public Utilities Staff Response: The proposal does not affect the currently approved plan for provision of public utilities. Section 7-107 Access and Roadways Staff Response: The proposal does not impact the current access and roadway requirements contained in Resolution 2012-80, except for the delay in constructing CR '114 improvements. The request to relocate the cul-de-sacs outside of the conserved areas is consistent with required road standards. It appears that the improvements to CR 114 were originally required to be completed by Spring Valley Ranch. A private agreement between Lake Springs Ranch and Spring Valley Ranch discusses the'sharing'of the costs of the improvement. This agreement was reached due to impact on the roadway from the Lake Springs Ranch development, and the road itself is included within Filing 2 of the Phasing Plan, see map below. There is no verbiage related to the phasing plan that appears to require the improvements at the stage of the development. ["i gurr' 5 l']rir{ i *lr.r !'l l;rsr,l{: i I i ns J,\ rr.';r Justification of the delay in road improvements includes the elimination of existing traffic generated by the sod farm, as the Filing 2 lots are located within the area of the sod farm. The net increase in traffic from Filing 2 is not sufficient to require the CR 1 14 improvements at this time based upon the LUDC standards. 6l Lake Springs Ranch Board of County Commissioners April 11,2016 Road & Bridge responded to the referral, Exhibit H, that the "...improvements to CR 1 14 at Filing 2 are important to the general safety of the development and the traveling public. Would recommend that they stay in place." Staff discussion with Chris Hale, Mountain Cross Engineering, and Mike Prehm, Road & Bridge, related to the timing of the improvements. From an engineering perspective there is no evidence that the improvements are necessary at the time of Filing 2, however Road & Bridge woutd like to see the improvements at the earlier possible time due to existing issues with the "S" curves adjacent to the pond. Section 7-108 Use of Land Subject to Natural Hazards staff Response: The proposed amendments will not affect this standard. Section 7-109 Fire Protection Staff Response: There do not appear to be any changes that would impact fire protection on the proposed development. DIVISION 2 GENERAL RESOURCE PROTECTION STANDARDS Section 7-201 Agricultural Lands Staff Response: The proposed amendments would not appear to impact this standard. Section 7-202 Wildlife Habitat Areas Staff Response: The proposed amendments do not appear to impact this standard. Section 7-203 Protection of Waterbodies Staff Response: Existing conditions on the site include two ponds and wetlands along the perennial stream in the area west of CR 1 '14 - the majority of the area is contained within the Agricultural Preserve which is encumbered by conservation easements held by AVLT. Two additional ponds are adjacent and east of cR 1 14 and located in a proposed open space area. One of the proposed amendment requests is to remove a condition of approval as it relates to the east pond. The condition of approval states: Condition 15. Prior to approval of the final plat for Block 3, the Applicant shall submit to the State of Colorado a Notice of lntent to impound water for the detention pond east and adjacent to CR 114 and received approvalfrom the State. The application originally was seeking removal of this condition due to proposed changes to the drainage plan. However the Applicant has amended the request to continue with the condition but to amend it as follows: Condition 15. "Should it be determined that stormwater detention is required to be stored in the pond on the east side of CR 114 the Applicant shall submit, and receive approvalfor, a Notice of Intent to impound water from the State of Colorado." The amendment to this request was the result of engineering comments that caused changes to the proposed revised drainage plan. Should the use of the pond on the east side of CR 1 14 be needed for stormwater detention the requirement is in place to obtain the necessary State approvals. TlPlgt Lake Springs Ranch Board of County Commissioners April 11,2016 Section 7-204 Drainage and Erosion Control Staff Response: A Revised Drainage Plan prepared by High Country Engineering (dated September 2,2010, Revised March 20,2015) indicates that the original drainage facilities have been determined unnecessary and therefore the request that the facilities be eliminated from the requirements of the development. Chris Hale, Exhibit G, states that the LUDC requires that detention and peak flow mitigation be provided. The Applicant has responded, Exhibits J and O, with explanation and revisions to the proposed drainage plan. Chris Hale has responded to the revised drainage plan dated July 27,2015 that this information has adequately addressed his concerns, Exhibits L and P. Section 7 -205 Envi ronmental Quality Staff Response: The proposed amendments would not appear to impact this standard. Section 7-2OG Wildfire Hazard Staff Response: The proposed amendments would not appear to impact this standard. Section 7-207 Natural and Geologic Hazards Staff Response: The proposed amendments would not appear to impact this standard. Section 7-208 Reclamation Staff Response: Not applicable. DIVISION 3 SITE PLANNING AND DEVELOPMENT Section 7-301 Compatible Design Staff Response: The proposed amendments would not appear to impact this standard. Section 7-302 Off Street Parking and Loading Standards Staff Response: The proposed amendments would not appear to impact this standard. Section 7-303 Landscaping Standards Staff Response: The proposed amendments would not appear to impact this standard. Section 7-304 Lighting Standards Staff Response: The proposed amendments would not appear to impact this standard. Section 7-305 Snow Storage Standards Staff Response: The proposed amendments would not appear to impact this standard. Section 7-306 Trail and Walkway Standards Staff Response: The proposed amendments would not appear to impact this standard. DIVISION 4 SUBDIVISION STANDARDS AND DESIGN SPECIFICATIONS Section 7-401 General Subdivision Standards Staff Response: The proposed amendments would not appear to impact this standard. Section 7-402 Subdivision Lots Staff Response: Lots have been redeslgned in the Filing 2 area to remove the cul-de-sacs from the conservation area. The development will remain in compliance with this standard. 8lPagc Lake SPrings Ranch Board of County Commissioners April 11, 2016 Section 7-403 Survey Monument Staff Response: The proposed amendments would not appear to impact this standard. Section 7-404 School Land Dedication Staff Response: The proposed amendments would not appear to impact this standard. Section 7-4OS Traffic lmpact Fees Staff Response: The proposed amendments would not appear to impact this standard. Section 4-113 REZONING The rezoning request may be processed concurrently with the land use change application and review process. G. Review Criteria An application for rezoning shall demonstrate with substantial evidence that an error exists in the Official Zone District Map, or meet the following criteria: 1. 2. 3. 4. The proposed rezoning would result in a logical and orderly development pattern and would not constitute spot zoning; The area to which the proposed rezoning would apply has changed or is changing to such a degree that it is in the public interest to encourage a new use or density in the area; The proposed rezoning addresses a demonstrated community need with respect to facilities, services, or housing; and The proposed rezoning is in general conformance with the Comprehensive Plan and in compliance with any applicable intergovernmental agreement. Staff Response: The proposed amendments appear to comply with these requirements. 6.401. DEVELOPMENT STANDARDS. At the time of zoning as a PUD, the Applicant may request that the BOCC modify the specifications, standards, and requirements to which the parcel(s) would be otherwise subject based on the zone district requirements set forth in Article 3. The BOCC may grant a modification if the Applicant demonstrates that the proposed specifications, standards, and requirements meet support the purpose of the PUD. ln addition, the PUD Plan shall meet the following criteria: A. Permitted Uses. B. Off-Street Parking. C. Density. D. Housing Types. E. Transportation and Circulation System. F. Recreational Amenities. G. Building Height. H. Lots. l. Phasing. Staff Response: The proposed amendments appear to be in compliance with the PUD development standards. 9ll"lg,: Lake SPrings Ranch Board of County Commissioners April 1 1,2016 AHTICLE S. INCLUSIONARY ZONING FOR HOUSING Staff Response: Article 8 of the LUDC requires that 10% of the units in a proposed development be affordable housing units. This differs from the 2008 Unified Land Use Resolution of 2008, as amended (ULUR) which required provision o'f 15"/" of the units in the proposed development be affordable housing units. The Applicant seeks to reduce the required number of affordable units from 18 to 1Z bas-ed upon the requirements of the LUDC. A revised Affordable Housing Plan and Agreement has been provided. Historically the development, as proposed in 1979, was not required to provide affordable housing, however when proposed amendments were submitted in 2012lhe development was required to comply with the code requirements in effect at that time. The ULUR required provision of 15"/".of the units as affordable, therefore the requirement for 18 affordable units was based upon the remaining 1 18 f ree-market single family lots proposed. Consistent with the prior requirement to provide affordable units in conformance with the code in effect at the time, the affordable housing for Lake Springs Ranch should be based upon the LUDC which would reduce the number of affordable units lo 12, based upon the 10% requirement. 1. Several of the requests are 'housekeeping' items that result in no issues with compliance to required standards - those include: a. The PUD and Preliminary Plan Amendments request to redesign 4 lots within Filing 2 so that the cul-de-sacs are not located within conserved areas; b. Revise language in Condition 14 of Resolution 2012-80 to clarify that the proposed water system must be reviewed under CDPHE requirements for a "community" water system. The current condition states that the proposed water system must be reviewed under CDPHE requirements for a "non-transient, non-community" water system. Morgan Hill, Environmental Health, responded in Exhibit I that the development appears to meet the 'Community" water system requirements of CDPHE. c. Correct to the Zone District Map to correctly identify the zoning of those exchange parcels (Rural and PUD) that were approved by the Board of County Commissioners in 2012. The remaining requests include: 2. Amend the drainage plan to allow removal of the on-site detention based upon a revised drainage plan. This request has not been adequately justified and, based on comments f rom Chris Hale, the Applicant has not demonstrated that detention and peak flow has been provided as required by the LUDC. The Applicant is required to submit evidence that the detention volume from the previously approved application is provided and that the flows are restricted to pre-project level in the meadow. The Applicant's engineer, High County Engineering, has submitted supplemental information, Exhibit J and Exhibit O, in response to the concerns identified by Chris Hale. Review of this information has resolved the issues identified and it appears that the second revised drainage plan meets the minimum standards of the LUDC. l0l['agc Lake SPrings Ranch Board of County Commissioners April 1 1, 2016 3. Remove the requirement for the State of Colorado of a Notice of lntent to impound water regarding the pond located east of CR 1 14. This pond was proposed to be used for on-site detention which would have resulted in the required approvalfrom the State of Colorado. It has not been determined that the pond would not be required for on-site stormwater detention thus Staff did not support the elimination of this condition of approval. The current condition states: Condition 15. Prior to the approval of the final plat for Block 3, the Applicant shall submit to the State of Colorado a Notice of lntent to impound water for the detention pond east and adjacent to County Road 1 14 and receive approval f rom the State. lnstead of eliminating the condition the Applicant has proposed to amend the language in this condition rather than to eliminate it entirely. The intent is to prevent application of a condition if this pond is not required for on-site stormwater detention. Exhibit K contains the Applicant's proposal as follows: Revised Condition 15. Should it be determined that stormwater detention is required to be stored in the pond on the east side of CR 1 14 the Applicant shall submit, and receive approval for, a Notice of lntent to impound water from the State of Colorado. This proposed revision to the condition satisfies Staff concerns. 4. The Applicant requests to amend the Preliminary Plan/Phasing Plan to accomplish the following: 11lt Lake SPrings Ranch Board of County Commissioners April 11, 2016 a. Delay Phase 2 improvements to CR 1 14 to Phase 3; Based upon the discussion above in the section of review of road standards required by Section 7-107 of the LUDC, it appears that there may be existing issues with the "S" curves in the area of the pond, however the generation of traffic from Phase 2 is not sufficient to require the road improvements at this time. Review of the historic information, particularly the phasing of public improvements, has not yielded a sufficient understanding of why these road improvements were deemed necessary at this time. ln fact the approved phasing plan is simply a map that indicates the sequence of development and it appears to include CR 1 14 in Phase 2. As a supplement to the revised phasing plan map on Sheet 9 of Exhibit M, the Applicant has provided a narrative of the phasing plan, Exhibit N. This narrative clearly indicates the sequence of future improvements related to the subdivision. b. Shift nine (9) lots from Filing 4 to Filing 3; and c. Remove the lot lines from areas described as "Conserved Lands". This request is contained in Supplemental lnformation, Exhibit Q, and resulted from discussions with staff regarding the progression of platting of the subdivision. lt appears that conservation easements were placed on lands shown in the Preliminary Plan containing residential lots however these lots were rendered undevelopable by the conservation easements. The LUDC requires that platting occur consistent with the approved Preliminary Plan and in accordance with the Phasing Plan. The Applicant would not be able to comply with these requirements with the current Preliminary Plan. 5. The Applicant requests to decrease the number of affordable housing units from the 15% required by the 2OOB ULUR to the 10% required by the 2013 LUDC. This will reduce the requirement from 18 to 12 units. Staff does not have an issue with this request as it is in conformance with the LUDC requirements. The Planning Commission considered these applications at a Public Hearing held on Wednesday, February 1O;2016. After deliberation the Commission unanimously recommended that Board of County bommissioners approve the requested PUD and Preliminary Plan Amendment with the following Finding and Conditions of approval. The proposed findings are based upon a Staff recommendation of approval of the requests to amend the PUD, the Preliminary Plan, and the Zone District Map: 1. That proper public notice was provided as required for the hearing before the Planning Commission. Z. That the hearing before the Planning Commission was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard at that meeting. 12llJ r g r Lake SPrings Ranch Board of County Commissioners April 11,2016 3. That for the above stated and other reasons the request for Preliminary Plan and PUD Amendments is in the best interest of the health, safety, convenience, order, prosperity and welfare of the citizens of Garfield County. 4. That, subject to compliance with conditions, of approval the applications are in general conformance with Gartield County Comprehensive Plan 2030. 5. That, subject to comptiance with conditions of approval, the applications have met the requirements of the Garfield County 2013 Land Use and Development Code, as amended. This approval will supersede and replace in its entirety the prior approvals granted in Resolution 2O12-BO therefore the required conditions contained in that resolution (with the exception of those conditions that were satisfied), as well as amended conditions of approval, are included below. For ease in understanding the changes to the conditions the strikeeu* indicates deletion and red indicates additions: Preliminarv Plan 1 All t€presentations of the Applicant made in the application and at the hearings before the planning Commission and Board of County Commissioners shall be considered conditions of approval, unless approved otherwise by the Board of County Commissioners. Fees 2. The Applicant shall include 50% of the road impact fee with each final plat. The remaining 50% shall be collected at the time of issuance of a building permit. The cost of any improvements to County roads that are constructed by the Applicant and approved by the County may be deducted from the road impact fee. All future Subdivision lmprovement Agreement(s) shall include any terms necessary to accomplish such deduction. 3. The Applicant shall pay a GashFee-ln-Lieu of School Land Dedication paYmen+-+e+ S€h€o's,ascalculatedinSection7.W404olthe2013LandUseand Development Code, as amended, with each final plat. 4. lmpact fees shall be paid to the Carbondale and Rural Fire Protection District prior to the approval of theJirst final plats submitted for approval subsequent to this Resolution' Permits S. Prior to the approval of each final plat, the Applicant shall obtain a National Pollutant Discharge Elimination System Permit and air pollution permits from CDPHE. These permits shall be submitted to Garfield County for review. Agreements 6. Approval of the Preliminary Plan requires the Developer to complete the platting of all phases within 15 years of Resolution 2012-80 and the first final plat must be recorded within one year of the final approval of the Preliminary Plan, or as may be extended by the Board of County Commissioners by resolution' Plat Notes 7. The following plat notes shall be placed on each final plat: 13lt'lgc Lake SPrings Ranch Board of county "if;ifi:%.i; a. Control of noxious weeds is the responsibility of the property owner in compliance with the Colorado Noxious Weed Act and the Garfield County Weed Management Plan. b. Colorado is a "Right-to-Farm" State pursuant to C.R.S. 35-3-101 , et. seq. Landowners, residents and viJitors must be prepared to accept the activities, sights, sounds and smells of Garfield County's agricultural operations as a normal and necessary aspect ol living in a County with a strong rural character and a healthy ranching sector. Those with an urban seniitivity may perceive such activities, sights, sounds and smells only as inconvenience, eyeiore, noise and odor. However, State law and County policy provide that ranching, farming or other agricultural activities and operations within Garfield County shall not be considered to be nuisances so long as operated in conformance with the law and in a non-negligent manner. Therefore, all must be prepared to encounter noises, odor, lights, mud, dust, smoke chemicals, machinery on public roads, livestock on public roads, storage and disposal of manure, and the application by spraying or otherwise of chemical fertilizers, soil amendments, herbicides, and pestitides, any one or more of which may naturally occur as a part of a legal and non-negligent agricultural operations. c.

Site specific studies shall be conducted for individual lot development. The need for site specific studies shall be disclosed in the covenants and on each final plat in the form of a plat note. Those recommendations include the following: a. Prospective building owners should be made aware of the potential low risk of evaporate deformation. lf the low risk is not acceptable to building owners, it can be reduced by the use of heavily reinforced foundation system preferably without a basement. b. lt is recommended that buildings not be located within 50 feet of the fault trace identified inFigure1oftheHPGeotechreportdatedJanuary15,2o10@ M as attached to this Resolution 2012-80. c. lt is recommended that additional subsur{ace exploration be made in these areas to evaluate the engineering characteristics of the lake deposit. These areas include Lots 6, 7, and 8 of Block 2 and 200 feet of the western most portions of Spring Valley Road. d. The recommended foundation system will depend on the site specific expansion potential. Also, a structural floor system over a crawlspace may be warranted depending on the expansion potential at a specific building site. A site specific foundation study by the individual lot owners should be conducted for design level 141[';igr Lake SPrings Ranch Board of county "iilfrfi:%1'; recommendations. e. More extensive grading should be evaluated on a site specific basis- As previously recommended, c-ut anOlitl should not exceed 10 feet deep and cut and f ill slopes should be 2:1(horizontal to vertical) or flatter.

Clvlt and Enulronmontal July 17,2015 Ms. Kathy Eastley Garfi eld County Planning 108 8rh Street, Suite 401 Glenwood Springs, CO 81601 RE: PUAA 8287 and PPAA E286, Lake Springs Ranch PIID Dear Kathy: This office has performed a review of the documents provided for the PUD and Preliminary Plan Amendment qpplications of Lake Springs Ranch PUD. The submittal was found to be thorough and well organized. Additionally io the review, a meeting was held with Dan Dennison and Roger NeU of Uigh Country Engineering on July 17,2A15. The review and meeting generated the following questions, concerru; and comments: L There were many conditions of Resolution 2012-80 that this application would amend. The Appticant should address how many of these conditions have been satisfied and which conditions still need to be addressed. 2. The Applicant should provide a design of the culvert proposed beneath the County Road and how this may change for either Option A or B. 3. The Appticant proposes to eliminate detention. This is justified by shifting the discharge point to the existing shallow ponding area in the meadow of the conservation easemenl This increases the tibutary area to include a larger oFsite basin that becomes the major generator of the peak flowrate. Because the proposed development area increases the impervious areas, ii drains more quickly, and the peak flow outpaces the existing condition. This area then no longer overtaps with the peak flows from the larger off-site basin creating a rather rare situation where the development condition decreases the peak flows when compared to the exiting. This is only the case because the discharge point was shifted downstream. The peak flows from the development still exceed the existing at the County Road. However, the LUOC requires that detention and peak flow mitigation be provided. Based on the meeting, the Appticant will provide evidence that the detention volume from the previously approved application is provided and that the flows are restricted to the pre-project levels in the meadow per the LUDC. This will be submitted to the County for review. Feel free to call if you would like to discuss any part of the review.

Eastlev loshua Willlaris RE: quetbn oo water systeDs a'tonday, fuly 20, 2015 u:19:10 Alt Hi Kathy, Great question- this one has been confusing for me over the years. I got things cleared up when we worked to get the Riverside Cottages changed from a ntransient, non-community" water system to a "community" water system because they were no longervacation rentals but were being rented year-round. I am not sure of the exact regulations that apply to each category, but you are certainly conect that a community water system has more strict regulatory requirements. They have to do more frequent sampling for more constituents, and I believe have to treat the water to a greater degree (for example, chlorination is required for a community water system but I don't believe it is for a transient non-community). The Water Quatity Control Division regulations can be found at: htt o:; //gmtw.qolorndo.Sovloat if irlsites/defaul t /files/1 l-eql $$3Eg5S?9.bdf . "coMMUNITY WATER SYSTEM" means a public water system that supplies at least 15 service connections used by year-round residents or that regularly supplies at least 25 year-round residents." "NON-COMMUNITY WATER SYSTEM" means a public water system that ls not a communlty water system. A non-community water system is either a "transient, non-community water system" or a "non-transienL non.community water system." ,,NON-TRANS|ENT, NON-COMMUNITY WATER SYSTEM" means a public water system that regularly seryes a population of at least 25 of the same people for at least six months per year and is not a community water system." ls that helpful? l'm looking at my calendar and see that this was due last Wednesday.

You pointed oul thot there ore londs locoted outside of the Filing I finol plot boundory thot ore shown os being within the Filing I oreo on the opproved (ond proposed) Phosing Plon. This conversotion led to severot reloted issues; one of which wos whether the Appliconts could be ollowed to proceed with the finol plotting of future phoses of the subdivision given thot there moy be o defect in the cunent finol plotting since there ore londs thot hove been conserved but hove not received finol plot opprovol. Concern wos olso expressed os to whether it wos oppropriote to hove compleled conservotion eosements on londs which hovq not received finol plot opprovol. lwos osked to provide the following in response to these issues: 1. lnformotion or documenlotion confirming thot lond need not be finol plotted before it con be sterilized through o conservotion eosemenh 2. A revised Phosing Plon or other solution for oddressing the discreponcy between the boundory of the lond contoined within the recorded Fiting 1 FinolPlot ond the Filing I oreo depicted on lhe Phosing Plon. Regording item number one I contocted Billsilberstein of Koplon Kirsch Rockwell ond MorkWeston. Billis o noted ottorney who speciolizes in conservqtion low ond Mork is one of the premier reol estote opproisers speciolizing in voluotion for conservotion eosements. Both Billond Mork hove worked on lond conservotion ond conservotion eosements throughout Colorodo. I olso reviewed the opproisols fhot were prepored for severolof the conservotion phoses of the Loke Springs Ronch subdivision. My conversotions with Billond Mork confirmed the opinion thot lexpressed during our meeting, which is thot the process of conserving subdivided lond through the dedicotion of o conservotion eosement does not require thot the subdivided lond be finql plotted. ln foct, lond in Colorodo hos been conserved oi vorious different poinls over the continuum of the lond use ond subdivision entillements process. iurlher, the stondords ond procedures for voluotion of lond for conservotion eosements do not define ony specific stondord for determining the highest ond best use for o subjecl property. I hove ottoched o recent decision from lhe United Stotes Tox Court (Schmidt v. Commissioner of lnternol Revenue), wherein the Court sides with the londowner on the question of whelher pending rezoning ond preliminory plon opplicotions could be used in determining the highest ond best use for puiposes of estoblishing the before volue for o conservotion eosement. ln this cose. which wos decided in August of 2014, no lond use or subdivision opprovols hod been formolly gronted. Nevertheless, the Court supported the opproiser's finding thot the highest ond best use wos residenliol lots, os described in the rezoning ond preliminory plon opplicotions, on the grounds thot "ihe record estoblishes tnot tne oppliconts hod been oble to oddress oll relevont issues thof could hove prevented or deloyed the gronting of development entillements for the subject property." Cleorly, this is o much lower stondord thon exisls in lhe cose of the Loke Springs't?onch PUD Subdivision, which hos received PUD zoning ond pretiminory pion opprovols for the entire properly ond finol plot opprovolfor o portion of 'the properly. We'd be hoppy to provide documentotion of other similor coses ii necessory. Regording ilem number two, I hove provided o revised Phosing Plon, with deicriptiv! text (text to follow on Mondoy),os we discussed. The revised Phosing plon drowing difierentiotes between the terms "phose" ond "filing" since use of the term filing on tnis drowing hos creoted confusion. The term "phose" on this drowing is intended to define the Appliconts' priorities regording the order in which development would occur, while "filing " represents o porticulor oreo thot hos been gronted finol plot opprovol. To ochieve this distinction we hove eliminoled the word "Filing" ond substituted the word "Phose" in lhe legend. ln oddition, we hove shown the entire oreo which wos included in lhe Filing I Finol Plot os "Phose lo {Filing I )", while the remoinder of the oreo thot hos been conserved is defined os'iPhoie ib." The resl of development is depicted os Phose 2, Phose 3, .'.etc. phose I o ond Phose t b combined represent the oreo for which no further development oction or entitlements ore necessory since it hos been conserved. By providing o revised phosing plon, which clorifies the distinction between pirosing on-O fiting, ond by providing documentotion supporl'ing ihe foct thot conserved lond need not be finol plotted, we believe we hove demonstroted thot there is no defect in fhe cunent enlitlements ond thot there is no need to either seek furl'her finol plol opprovols for londs olreody conserved or to preclude the Berkeleys from pursuing finol plot opprovol for future phoses' ln the course of revising the Phosing Plon vre found severol minor revisions thof we believe should be mode to the Preliminory Plon drowings. A revised sei ol preliminory Plon drowings is ottoched. We would note thot the Preliminory Plon drowings continue to use the Lot ond Block nomencloture ond the descriptive text for the pfrosing plon describe which blocks ore included in which phose. The chonges mode to the Preliminory Plon drowings ore listed below: '1. Updoted cover sheei to remove "filing" reference of top of Lond Use Summory. 2. Updoted cover sheet to removed "development oreo" in Sile Doto Summory. 3. Removed "Filing l " lobel from oll Key Mops- 4. Removed note l1 from cover sheei since lhis relotes to tronsfers of lond from cMC ond Neislonik which hove olreody been completed. 5. Chonged sheei I for new phosing ond eliminolion of filing 2, filing 3, etc. from longuoge. lwos olso osked to provide o revised droinoge plon. os menlioned in the letter from HCE doled July 21. 20'15, oddressing Chris Hole's refenol commenls reloted to droinoge, Don Dennison hos indicoted thot the revised droinoge plon should be reody by Mondoy. He hos osked me io inquire how mony copies oUhe revised droinoge plon you will be needing? homments Regcrrcling Droft Conditions I hove only one commeni regording the droft conditions, it concerns Condition 6 ond is reloted to the ptotting issue discussed previously in this emoil. The woy the condition currently reods, il required thot my client "plot" oll phoses of lhe developmeni within l5 yeors. While we undersiond the purpose of this condition we would point out ihot strict odherence io it would require thot we finol plot the portion of the oreo which hos olreody been conserved ond is outside the Filing I boundory. We betieve ihot ploiting this oreo is unnecessory, os no development or lot soles will be occurring, ond creoies on owkword situotion since the County would most likely be reluctont to plot lots thot hove olreody conserved, os wos expressed by Kelly during our meeting yesterdoy. Perhops this longuoge could be modified to preserve the County's intent, to prevent developers from obondoning porl'iolly compleled projects, while ovoid the plotting of conserved londs issue. lf ihere is support for the ideo of modifying ihis condition I would hoppy to provide some droft longuoge. Hove o greot weekend ond let's discuss lhese motters on Mondoy.

Lake Spring Ranch PUD subdivision is proposed to be constructed in five separate phases. The phasing plan can be seen on sheet PIan-09 of the Preliminary Plan with the revision date of 7 /24!15. Phase I includes land that has been sterilized through the dedication of conservation easements. Phase 2-6 are the five phases where proposed lots and infrashr:cture are planned. Phase 2 (Block 2) includes l4 lots that will be served off of the existing west side of County Road I 14. The roads to be constructed include Spring Valley Road, RivendellCourt, and Rivendell Road flor a total length of approximately 1,550 feet. This phase also includes a gravel access road up to the well and tank locations in order to provide the rvater supply for Phase 2. Phase 2 will also include the start of construction for gas, electric, telephone, domestic water, and sanitary sewer. The property lvill be served by Source Gas natural gas by extending a line up County Road I l4 from the existing Los Amigos regulation station to the south of the property. The Holy Cross electric service will be provided by installing underground electric line up from the existing power poles along running east to rvest along the southern edge of the property. The CenturyLink telephone service will be provided by installing underground lines up from the Colorado Mountain College from the south. There is already a Spring Valley Ranch Sanitation District sewer main cutting across Phase 2 that is sized to handle the full buildout of Lake Springs Ranch. The water tank, pumphouse, and water main to connect Phase 2 to the tank lvill all be required with the construction of the first developed phase. All of the utilities for the rest of the phases can extend off of the utiliry infrastructure installed in this first phase of the PUD. Phase 3 (Block 3) includes 27 lots and a multifamily tract on the east side of County Road I 14. This phase includes Lakeside Lane, Hanging Valley Road, and the southem 2,930 feet of Lake Springs Drive. Counry Road I 14 ivill be rebuilt from the southern to the northem edge of Lake Springs Ranch PUD. This reconstruction of County Road I l4 rvill involve the rvidening of the road throughout, the installation of drainage ditches as necessary, and the straightening of the road on the south end of the property near the existing pond. This work rvill include reconfiguration and lining of the west side of the pond. These improvements will improve vehicle safety and protect the counry road from damage related to seepage from the pond.

Property Location The proposed development, Lake Springs Amended PUD, is an approximately459.38 acre site with Spring Valley Road and County Road I l4 located within the center portion of the project. The proposed development consists of 194 single-family lots (77 ofrvhich have been sterilized through a conservation easement), with the typical lot size being 0.9 acres. The smallest lot within the subdivision is 0.658 acres- See Exhibit I for the Vicinity Map. There is a significant area of offsite drainage affecting this property from the east, west, and south of the property. B. Property Description This site is located on approximately 459.38 acres of undeveloped pasture/grassland that slopes toward the west to the low lying area on the property currently surrounded by a sod farm operation. The overall site is relatively sleep with sunounding steep hills and drainage ways- The existing low point of the property leaves the properly to the north across County Road I 19 and eventually to the Roaring Fork River. The seven soil types located on the site are within hydrologic soil groups 'B', 'C' and 'D'; per the NRCS soils map. Refer to Exhibit 4 in the appendices for the descriptions of the soils. The proposed site consists of natural gft$ses, roadways, a pond, and ditches. The proposed development is delineated as Zone C from the Flood Insurance Rate Maps, Community Panel 08020514655 B, dated January 3, 1986. ZoneC is defined as areas of minimal flooding. II. DRAINACE BASIN CRITERIA A. Regulations AutoCAD's SCS TR-55 Tabular Method was utilized for this report for onsite and offsite runoffto remain consistcnt with the Garfield County standards. NOAA Atlas maps for the 25 and lfi)-year rainfall intensities were used to determine runoff from each basin. Per the NOAA Atlas, the 2-year, 24 hour precipitation amount is 1.2 inches, the 25-yeaq 24 hour precipitation amount is 2.0 inches and the 1OO-year, 24 hour rainfall intensity is 2.4 inches. Peak on-site flows for this site rvill be primarily rainfall derived since the entire site is below 8,000 feet in elevation, Therefore, the storm drainage system should be more than adequate to handle on-site spring snowmelt nrnoff when sized for the rainfall events. The AutoCAD hydrology channel calculator was used for channel sizing during the 25-year and lO&year storm eyents- AutoCAD's pipe calculator was used to size the culverts for the 25-year storm event pcr the Garfield County's specifications. Weighted curve numbers based on the soil types and land uses were used to determine the runoff from each of the basins. 4lPage B. Hydrologic Criteria The proposed development characteristics were broken down to open space, roadways, and propor.d development (0.9-acre typical single family lot size). The existing basins were modeled as having open pasture/grasslands in fair condition as well as asphalt roadrvays. The proposed site wiliultimately undergo grading for the proposed roadways, drainage facilities, and the proposed I acres single-family lots. III. DRAINAGE FACILITY DESICN A. Oflsite Basin Description Six offsite basins located around the proposed site contribute runoff to the west end of the subdivision. Most of these basins do not affect the proposed lots since they are routed around the proposed lots to the agricultural western end of the property where much of the land has b""n "ons"rved. The offsite basins were analyzed to determine the amount of runoffthat ends up in the low lying portion of the property. The offsite culverts that convey the offsite diainage to the proposed detention pond were not analyzed to determine if they had enough ."pr"ity to conveyto the proposed ponds since these culverls are outside the scope of our drainage design. The major existing basins (EX-OS I ) that is routed through the west end of the prop"rry haJa time of concentration of 113.22 minutes, while the proposed time of concenLation for the onsite basins to the to the low end of the property are all below 32 minutes. So the basins will not peak at the same time when they travel through 0re low end of the property where all the basins eventually end up. The lag time will provide suflicient time for itre proposed onsite drainage runoffto peak in the west end ofthe propertytefore the major existing oifsite basin reaches a peak flow. EX-OSI is 5 times the size of the entire Lake Springi Ranch and thus the peak flow at the end of the property is controlled primarily by the offsite basin. Offsite basin EX-OSI encompasses the area to east and north ofthe proposed site. The runoff from basin EX-OSI drains south, near the eastern property boundary, then west below the southern property boundary, where it then crosses beneath County Road ll4 vla existing culverts. EX-OSI reeeives runofffrom existing basins EX-2, EX3, EX-4, and EX-5. EX- OSI also receives runofffrom proposed basins PR-21, PR-25, PR-27, and PR 31. This runoff from EX-OSI then enters EX-OS6 west of County Road l14 and then travels northwest to the proposed detention ponds within the proper.ty discussed later herein this report. EX-OS6 ilsoreceives direct runoff from a number of onsite basins that flows down County Road I l4 and from the existing landscapelinigation pond on the eastside of County Roadi14whichmakesupEX-l0aswellasEX-OS-S. Theproposedbasinsthatdirectlyflow to EX-OS6 include PR-8, PR-16, and PR-17. The additional flow generated by the build out otthe property will increase the overall flow onto the Colorado Mountain College property that sift within EX-OS6 but there is a signed agreement with the College (Exhibit 8) that allows a percentage increase in flow during the major runoffevents. This has been the path of 5lPu1:e the existing runoff from the landscape/irrigation pond historically and it rvas determined that the College had no intention to develop this corner of the property. Offsite basin EX-OSS is located near the southwestern corner of the property, between the properiy boundary and County Road I 14. The runofffrom this basin drains northwest to a low point and culvert near the east side of the County Road I 14. Offsite basin EX-OSS is located nor{r of basin EX-OS4. Offsite basin EX-OS4 is also in the southwestem corner of the properly and drains north into basin PR-I7 and then is collect by EX-OS5. Offsite basin EX-OS3 is located north of the proposed development and drains onto the development through existing basin EX-8 and proposed basin PR-1. The runoff from this basin ends up entering the northern end of the low lying area on the west end of the property. Offsite basin EX-OS2 is above the norlheast comer of the development. The runofffrom basin EX-OS2 drains along south side County Road I l4 and into existing basin EX-10 and proposed basin PR-10. All ofthe offsite basins defined eventually end up in basin EX-l which is abasin that includes sorne onsite land within the existing sod farm including the two existing inigation ponds and some offsite areas to the west of the property. This basin will not have any development occurring as part of the subdivision build-out other than some modifications to the outfall of the northem pond across County Road I l9 and any necessary culvert improvements for any agricultural property improvements. The "pasturdrassland-fair" curve number for soil qtpes 'B' (CN 69), 'C' (CN 79), and 'D' (CN 84) and "asphalf'(CN 98) curve numbers were used to create composite curve numbers for each drainage basin.

Onsite Basin Description Onsite runoff sheet flows to existing gullies where it is routed offsite in shallow concentrated flows. Each lot rvill be graded to convey the runoff from the lot to the proposed roadways' Runoff from the offsite basins will be routed through the proposed site to their historic discharge points. The proposed Lake Springs Amended PUD site was designed to carry the 25-year storm event down thl roadside swales to proposed culverts throughout the site. In the event of a 100-year storm event, the runoff will be safely conveyed through the property across roads, down property lines, and along the roadside swales to the proposed detention facilities. Any ietintion volume required onsite would be sized to accommodate the increase in flow between the onsite Zi-year peak runoff versus the onsite 2i-year peak runoff rates. rv. EXISTINq BASINS The existing site was broken down into t 0 onsite drainage basins that cover the entire property. Existing basin EX-l is located in the westem portion of the site as well as some of.it" iand to the west. This basin includes lowest points on the properry where most of the offsite and onsite basins are conveyed prior to exiting the property. There are currently areas of irrigation storage and wetlands at the lowest points of the properU. Any modifications to the conserved portion of this basin would require approval by the Aspen Valley Land Trust. AVLT has given preliminary approvat for passing additional flow through the conserved property ar long ai major grading is not required. The runoff from basin EX-l florvs north ".rog ttre Rat frtions of t[e development and is captured in the existing ponds when the rain event flows aielargeenough. The northern pond is currently used as a source of irrigation water belorv the outfall culverts to County Road 119. Existing basins EX-2 and EX-3 are basins on the northeast comer of the property that flows east to basin EX-OS l. Basin EX-4 and basin EX-5 are basins on the south side of the properly that also flow directly to EX-OS l. Basin EX-6 is on the southeast corner of the property and flows west to EX-OS5. Basin EX-7 and EX-9 are located on the north end of the property and flow north and do not eventually end up in EX-l with the rest of the basins. Basin EX-8 makesupmostofthelandbehveenCountyRoad l14andEX-l anddrainsdirectlytoEX-I. Basin Ei-tO includes much of the land east of County Road 114 and drains directly to EX- os6. The "pasture/grassland-fair" curve number for soil ffis 'B' (CN 69)' 'C' (CN 79), and 'D' (CN 84) and "asphalt" (CN 98) curve numbers were used to create composite curve numbers for each drainagi basin.

PROPOSED BASINS The proposed construction within the site consists of the construction of roadways, drainage Acititiei, and residential lots. The lots range in size from approximately 0.65 acres and 1.7 acres. The proposed lots were assumed to be walkout style lots in many cases. The proPosed lots will noi bgoverlot graded as part of the subdivision scope of work but for purposes of the drainage study the basin lines fit our expectations of the how the final grading of the lot will be addressed. @ appendices for SlFagt The proposed site was broken down into thirry-four basins. Many of these basins could be .orUiniO to create larger basins, but the basins were sized in order to correctly size the proposed culverts throughout the subdivision and to make sure that the roadside swales were iir"d lurg" enough to irandle the flows from lhe basins when the grading plans fo: the individual phases of the project are completed. Most ofthe property eventually drains to EX-l before exiting the property at the low point of Counry Road I 19. Basins PR-33 and PR -34 wilt be routed to a proposed drywell for rvater quality treatment before draining to the north- There will also be a drywell to provide some rvater quality for proposed Basins PR-29 and PR-30 before draining to EX-OS I which is off the property. The irywells are not required for detention volume since there is not an increase in flow for the 25yr storm from exiiting conditions. Refer to the drainage basin maps 3-3F for proposed basin locations and information. There are a number of basins that will temporarily leave the property before being routed to basin EX-1. These basins do not increase the runoff to EX-OS I by not including the areas of the homes, roads, or drivervays in the basin and so do not increase the runoff beyond the existing flowrates. These basins include PR-17, PR-21, PR-25, PR'77,and PR-31. There will not be any driveways or building envelopes within these basins. The rest of the proposed basins either drain directly to EX-l or are conveyed through the northeast co*"i ofthe Colorado Mountain College property before entering EX-l. These basins that are routed through the CMC property have been approved by CMC to bave an increase in flow for the buitd-out of the properg along a defined approximately 1,500 LF path' AutoCAD's TR-55 hydrology curve numbers for residential lots of l-acre were used for all lots, asphalt roads were used for all impervious areas, and pasture/grassland-fair curve numbers were used for all undeveloped areas. Composite curve numbers were determined for each basin using the curve numbers previously above within soil types for the undeveloped pasture/grassland areas. The areas within the developed lots will have a curve number for soil types .B; (CN 68), .C, (CN 79), and'D'(CN 8a) and "impervious" (CN 98) curve numbers were used to create composite curve numbers for each drainage basin.

Grass lined channels and culverts will be utilized to convey the proposed runoffto EX-1, as well as offsite to historic locations. VI. RESt'LTS AND RECOMMENDATIONS The majority of the site will be routed to the low end of the properly within basin EX- I . The only basins that will direct discharge from the site without ending up in basin EX-l are basin EX-7, PR-33, and PR-34. These basins will sheet flow offsite to the north and to the west dorvnstream of EX-l. The flow is not increased from these basins so there is no reason to include in the detention calculations. The lower portions ofEX-l have existing wetlands and irrigation storage in the middle of the existing sod farm operations. This area is capable ofpassing the 100-yr existing and proposed flow and not affect any of the lowest residential lots in Filing 2. The existing runoffto EX-l is 265.98 cfs for the 25-yr storm and 443.05 cfs for the 100-yr storm. The proposed runoffto the detention pond area is 261.58 cfs for the 25-yr storm and 436.05 cfs for the 100-yr storm. The outfall from the property will be at the low point along Counry Road I 19. Culverts will be installed at this location to convey the 25-yr storm under the llf[t*ge County Road during the first phase of construction. This will require the installation of nvin 48" diameter culverts to convey the 261.58 cfs flowrate. The 100-yr storm will be allowed to pass over the top of the road which is the historic path of the major mnoffevents when the County Road I l9 was constructed. This version of the Lake Springs Ranch drainage study is a reflection of an expansion of the area of influence from storm events to include all of the agricultural land on the west end of the property which includes the parcels of land that have been conserved over the last decade. thise areas also required an expansion of the offsite basins that impact the property. The calculations of the curve numberi for each individual proposed basin rvas also reevaluated in order to keep up with the most current street and lot layout. This correction for the 25-year 24-hour designitorm event and the revised routing of the drainage basins resulted in a small reduction in the peak flowrate for the proposed build-out of all the filings of the subdivision. The proposed onsite basins within the subdivision are peaking earlier than the existing onsile basins. This means the overlap of the onsite peak flows from the major offsite basin is reduced and thus reduces the overall peak flowrate. There rvill not be an increase in the runoff from the properfy during the 25-year 24-hour storm event which is the basis for calculating detention in Garfield CountY. This wetlands and sod farm portion of the property is the only area where most of the onsite proposed basins and the large offsite basins see overlap in the flows. This area is framed- on th" north by a berm that is located just south of the County Road I 19 and to the south by the lowest existing elevation along the boundary of the Colorado Mountain Collegi. Because this area remains undeveloped (other than for sod production) it can be utilized for storm water detention by simply raising the elevation of the berm adjacent to CR I19. Although the 25-year storm calculations do not reflect the need for additional detention, raising the berm would provide extra detention capacity. The creation of some additional detention storage would allow the development to account for some minor storm event models where runoffmight see an increase in runoff other than the 25-yr storm event- The additional storage also will slow the release of the runofffrom the onsite basins which have a much smaller peak than the major offsite basin creates. The existing elevation of the berm is at approximately 6899.0'. The maximum elevation thar the berm could be raised is 6900.5'. This small modification would allow for an additional 1.5' deep of detention storage above the existing irrigation storage over a large area. This adds approximately 1,500,000 cubic feet (34.4 acre feet). The additional flow directly from tbe inigation pond on the east side of the County Road I 14 produces approximately 13 cfs in additional nrnoff during the 25-yr storm. This equates to apiroximately 52,000 cubic feet of detention storage during the 25-yr storm event to match thi historic runoffrate. Therefore the modification to the berm provides storage far beyond the detention storage needed when the major offsite basins are ignored in the analysis as was the case in the previous County review. The concept of increasing the elevation of the berm to create the additional detention storage has been reviewed with AVLT and they have provided a letter stating that this improvement is consistent with the terms of the Berkeley's eonservation easement. 12lFaee The minimum culvert size of 18" diameter CMP will be installed unless the basin calculations show a need to upsize the culverts. The culverts throughout the suMivision will be sized according to the 25-yr 24-hr storm from the individual proposed basin as part of the final plans for the in-tlividual fiiings. The proposedZi-yrZ4ltv storm event (62 cfs) from the basins on the east side of CR I l4 require a 36" diameter CMP pipe at a slope of 12.66%. The drainage swales along County Road I 14 will be l0' wide and 2' deep minimum as was determined in earlier approvals. The rest of the roads within the subdivision will have a minimum of 6' wide and 18" deep swale. All of the roadside swales and major swales along property lines will be verified for capacity as final plans for each filing are submitted to Garfield County for review. VII. CONCLUSIONS The drainage facilities have been designed per Carfreld County's standards and regulations. The proposed storm drainage facilities have been designed to accommodate the runoff from ttris iite. The proposed storm rvater llows will be trealed and detained prior to discharging offsite and runLffrom the proposed site will be kept at or below historic levels for both the Z1-year and lQ&year storm events. The lower portions of the Propeily will be revised by raising the berm at the northwest corner of the properly in order to provide additional runoff .to.f" alihough not required according to the drainage calculations. The drainage calculations were based upon the above-stated assumptions and are subject to change upon final site design and build out and any modification in the grading plans of the individual phased construclion plan sets.

This leiter oddresses on issue which wos roised during the County Sioff's review of the originol opplicotion. The issue stems from the fqct thot there ore londs within the Loke Springs Ronch PUD Subdivision thot hove been sterilized through o conservotion eosement but for which no finol ploi hos been opproved or recorded. The Stqff ond the Appliconts hove ogreed thqt the best woy to resolve this situotion is for the Appliconts to seek opprovol for o finol plot thot shows the un-plotted sterilized oreo os "Conserved Londs." The requested preliminory plon omendmeni is intended to ovoid the situotion where o future opplicotion to finol plot the conserved londs could potentiolly be denied solely on ihe grounds thot the finol plot is inconsistent with the Preliminory Plon thot wos opproved in 2012. This opplicotion supplement includes o revised set of Preliminory Plon drowings ond o revised Phosing Plon (including norrotive). These drowings ond the revised phosing plon norrotive ore intended to reploce the drowings ond norrotive provided with the originol opplicotion. This letter oddresses the review criterio for o mojor omendment to o Preliminory Plon solely for the omendment reloted to the conserved londs os described in ihis document. The criterio for the Preliminory Plon omendments thot were requested in the originol opplicotion ore oddressed in thot opplicotion ond ore not repeoted in this supplement. As requested, we hove provided two hord copies of this opplicotion supplemeni ond o digitol copy in PDF formot on CD.

E-moil: tim@tgmolloy.com LSR PUD & Preliminory Plon Ap. /Conserved Londs Applicotion Supplement November 6, 2015 Poge l2 Bockground During ihe Stoff 's review of the originol Loke Springs Ronch PUD/Preliminory Plon Amendment opplicotion (Originol Applicotion), the Appliconts were informed of on issue reloted to londs which hod been conserved in the post but for which no finol plot hod been recorded. The Stoff hos indicoted thot the County requires thot oll londs within o subdivision must be finol plotted ond thot this position is supporied by condition number six of Resolution 2012-80 (resoluiion opproving most recent Preliminory Plon omendment for Loke Springs Ronch PUD). This condition siotes thot "Approval of the Preliminory Plan requires the Developer to complete the plaffing of atlphoses wifhin l5 yeors of fhis Reso/ufion ond the first finol plot musf be recorded within one yeor of the final approval of the Preliminory Plon."t The Stoff hos olso indicoted thot they would be unwilling to process ony finol plot opplicotion for future phoses of the Loke Springs Ronch Subdivision until oll of previously- conserved londs hod been finol plotted. The Appliconts were olso informed thot ihe County would be highly unlikely to opprove o finol plot opplicotion thot showed residentiol lots on londs for which conservotion eosements hod olreody been recorded, regordless of whether the opproved preliminory plon showed residentiol lots within the conserved oreo. Obviously, these interpretotions leove the Appliconts in the uncomfortoble position of not being oble to pursue further finol plotting of the subdivision until plotting of the conserved londs hos been completed. To fully understond how the Appliconts found themselves in this situotion it's importont to briefly review the opprovol ond conservotion history ossocioted with the Loke Springs Rqnch PUD/Subdivision (LSR). The Boord of County Commissioners gronted preliminory plon opprovol for LSR in 2002 vio Resolution 02-,l09. Resolution 02-109 includes the some condition quoted in the previous porogroph regording the need to complete plotting of oll phoses within 15 yeors. ln 2004, the County gronted finol plot opprovol for LSR Filing l, which encompossed 2l lots locoted in the northwest corner of ihe subdivision ond the entire Agriculturol Reserve oreo. Filing I contoined opproximotely I lB.5 ocres ond is depicted on the ottoched Context Mop (Exhibit I ). Subsequent to the opprovol of Filing l, the Appliconts begon preserving lond through o series of six conservotion eosements. The first of these, which wos finolized in 2004, involved lond thoi wos locoted entirely within Filing l. The second conservotion eosement wos done in 2005 ond contoined opproximotely 30.8 ocres of lond. This eosement, os with oll of the subsequent eosements, conioined lond which wos portly within Filing 1 (portions of the Agriculturol Reserve oreo) os well os londs locoted outside of the Filing I boundory. Exhibit 2 shows the lond oreo I The Appliconts note thoi the Boord of County Commissioners hove gronted extensions to the finol plot deodline referenced in this condilion ond thot .the current preliminory plon opprovols will not expire unlil April of 2016. 402 Pork Drive .

For eoch of ihe five eosements recorded ofter 2004, the lond locoted outside of the Filing 1 boundory is comprised of residentiol lots for which preliminory plon opprovol hod been gronted pursuont to Resolution 02-109 but for which no finol plot hod been opproved or recorded. Therefore the problem, which the Appliconts ore now seeking io resolve through the Preliminory Plon omendment requested in this opplicotion supplement, hos existed since 2005. ln 20ll the Appliconts submitied on opplicotion seeking vorious omendments to the preliminory plon ond PUD zoning opprovols grontedin 2002. The omendments requested in 20.II offected londs locoted ouiside of the conserved oreo. This opplicotion wos reviewed pursuont to the process for o mojor omendment, which required review by both the Gorfield County Plonning ond Zoning Commission ond the Boord of County Commissioners. The opplicotion wos olso reviewed by County Sioff, including the County Attorney's office, os well os severol outside ogencies. The opplicotion wos ultimotely opproved by the Boord of County Commissioners vio Resolution 2012-80. During the review of the 201 1 opplicotion there wos no mention of the issue reloted to the un-plotted conserved londs or ihe inobility to pursue further finol plotting of the subdivision os contemploted on the opproved Preliminory Plon. Descriplion of Proposed Amendmenl As o first step toword resolving this issue, the Appliconts ore proposing to omend the Preliminory Plon to show the portion of the Conserved Areo locoted outside of the Filing I boundory os "Conserved Londs" ond to eliminote the lot lines which ore shown on ihe opproved Preliminory Plon for this some oreo. The proposed omendment does not offect ony lond for which finol plot opprovol hos been gronted (Filing 1 ). The right-of-woy for Spring Volley Rood, which runs through the conserved londs, will not be offected by this omendmeni ond continues to be shown on the Amended Preliminory Plon drowings (Exhibit 4). ln oddition, there is o troil segment thot runs through o corner of the conserved oreo neor Kendoll Rood (CR 1 19) on ihe opproved Preliminory Plon, which will olso be retoined os reflecied ihe Amended Preliminory Plon drowings. The requested omendments ore reflected on the ottoched Amended Preliminory Plon drowings (see Sheels2,3,4, ond 8 of Exhibit 4). The un-plotied conserved londs, which ore the subject of this opplicotion supplement, will be referred to os the "Amendment Areo" for the remoinder of this document. Exhibit I illusirotes the relotionship between the Conserved Areo, Filing I ond the Amendment Areo, which includes the remoinder of the Conserved Areo thoi hos noi been finol plotted.

Exhibit 3 includes o phosing plon drowing ond o motching norrotive text. The phosing plon included wiih this opplicotion supplement olso reflects the other phosing omendments shown on the phosing plon included with the Originol Applicotion. The only differences between the phosing plon provided with this opplicotion supplement ond the plon included in the Originol Applicotion ore the chonges mode to more occurotely reflect the recorded boundories of Filing l, ond to include the un- plotted portion of ihe conserved oreo (Amendment Areo) with the lots proposed to be plotted in Filing 2.

The Originol Applicotion includes o description of the more substoniive omendments to the Phosing Plon ond o discussion of the review criterio for omending the PUD pursuont to Section 6-401(l) of the Gorfield County Lond Use ond Development Code (LUDC). Since the Phosing Plon omendments discussed in this opplicotion supplement ore relotively minor ond ore merely iniended io resolve prior inoccurocies with respect to the boundories depicted for Filing I ond to ollow for the timely resolution of the un-plotied conserved londs, no further discussion of the PUD criterio is needed over ond obove whot hos been provided in the Originol Applicotion.

The criterio thot must be met ore contoined in Divisions I through 4 of the stondords section of the LUDC (Article /).

Response: As stoted in the Originol Applicotion, the underlying zoning in this cose is the existing PUD. No chonges to the ollowed density or ollowed uses described in the PUD Guide, which wos lost omended in 2012 (Reception No. 842009), are proposed with the Originol Applicotion or with this opplicotion supplement. The recorded PUD Guide wos provided os Exhibit 21 of the Originol Applicotion. A revised PUD Guide wos olso provided with the Originol Applicotion (Exhibit 22). The proposed revisions to the PUD Guide ond the reosons for those revisions ore discussed in the Originol Applicotion. As demonstroted in the following porogroph, no rezoning or other revisions to the PUD zoning or the PUD Guide ore necessory in ossociotion wiih the Preliminory Plon omendment being requested with this opplicotion supplement. The londs within the Amendment Areo ore currently zoned residentiol single-fomily (R/Sf) ond open spoce (OS) on the recorded PUD Zoning Mop (see Exhibit 2l of the Originol Applicotion). Both of these zone disiricts permit open spoce, recreoiion ond ogriculturol uses omong the uses ollowed by right. ln oddition to these uses, the R/SF district olso lists single-fomily residentiol omong the uses ollowed by right. The lond within the Amendment Areo is currently being utilized for ogriculture ond open spoce. Since the future use of the conserved londs is limited to ogriculturol, open spoce ond possive recreotionol uses under the recorded Deed of Conservotion Eosement (DOCE), there is no need to rezone the conserved londs or to moke ony further revisions to the PUD zoning to oddress ollowed uses. Similorly, since the DOCE prohibits further subdivision of the conserved londs; ond since no residentiol development will occur on the conserved londs; the oreo ond bulk limitotions qssocioted with the R/SF ond OS districts (minimum lot oreo, building setbocks, etc.) will hove minimol opplicobiliiy. Similorly, the moximum building height resiriction hos limited opplicobility within the conserved oreo since no significont structures CIre permitted under the DOCE. However, even if such structures were ollowed, ihe moximum permitted building height (25 feet) is the some for oll of the zone districts described in the PUD Guide. 7-tA3 Comootibilitv: The noture, scole, qnd intensily of the proposed use ore compotible with odjocent lond uses. Response: The intended use of the lond within the Amendment Areo will continue to be ogriculture ond open spoce os permitted under the DOCE ond the PUD zoning. With the exception of ihe northernmost boundory, which obuts the odjocent Spring Volley Ronch PUD (SVR), the Amendment Areo is on internol portion of Loke Springs Ronch.

The phasing plan can be seen on sheet Plan-09 of the Preliminary Plan with the revision date of 10113115 and on the phasing plan attached to this narrative. Filing I includes a portion of the land that has been sterilized through the dedication of conservation easements. Filing 2-6 arethe five phases where proposed lots and infrastructure are planned. Filing 2 (Block 2) includes 14 lots that will be served off of the existing west side of County Road 1 14. The roads to be constructed include Spring Valley Road, Rivendell Court, and Rivendell Road for atotal length of approximately 1,550 feet. This phase also includes a gravel access road up to the well and tank locations in order to provide the rvater supply for the lots rvithin Filing 2. This road will be built within an access and utility easement across future filing land. Filing 2 also includes 76.1845 acres of land that has already been sterilized through conservation. This portion of land includes a 60' wide right-of-way easement for County Road 1 19 that was created in the Filing 1 plat. Filing 2 will also include the start of construction for gas, electric, telephone, domestic water, and sanitary sewer. The property will be served by Source Gas natural gas by extending a line up County Road 1 14 from the existing Los Amigos regulation station to the south of the property. The Holy Cross electric service will be provided by installing underground electric line up from the existing power poles running east to west along the southern edge ofthe property. The CenturyLink telephone service will be provided by installing underground lines up from the Colorado Mountain College from the south. There is already a Spring Valley Ranch Sanitation District sewer main cutting across Filing 2 that is sized to handle the full buildout of Lake Springs Ranch. The water tank, pumphouse, and water main to connect Filing 2 to the tank will all be required with the construction ofthe first developed phase. All of the utilities for the rest ofthe phases can extend off of the utility infrastructure installed in this first phase of the PUD. Filing 3 (Block 3) includes 27 lots and a multifamily tract on the east side of County Road 1 14. This phase includes Lakeside Lane, Hanging Valley Road, and the southem 2,930 feet of Lake Springs Drive. County Road I 14 will be rebuilt fi'om the southern to the northern edge of Lake Springs Ranch PUD. This reconstruction of County Road 114 r.vill involve the widening of the road throughout, the installation of drainage ditches as necessary, and the straightening of the road on the south end of the property near the existing pond. This work r.vill include reconfiguration and lining ofthe west side ofthe pond. These improvements will improve vehicle safety and protect the county road from damage related to seepage from the pond. Filing 4 (Block 4) includes 20 lots on the southeast portion of the Lake Spring Ranch PUD property. This phase includes approximately 1,800 feet of Lake Springs Drive, 880 feet of High Alpine Drive, and all of High Alpine Way. Filing 5 (Block 5) includes 37 lots on the northeast portion of the property. This phase includes all of Van Cleve Lane, the final 1,500 feet of Lake Springs Drive to the north intersection of County Road 1 14, and the final 1,870 feet of High Alpine Drive to the northem connection of the property to County Road I15. The final phase of construction will be Filing 6 (Block 6) '*'hich includes 20 lots on the northu'est side of County Road 114.
