The sketch plan appears to show more trees on the site than actual field conditions. lt also appears that the existing potato cellar is not indicated on the sketch plan. The addition of the four accessory dwelling units would result in slightly higher density than the Garfield County Comprehensive Plan recommendation for the area. Thank you for referring the Roaring Fork Preserve sketch plan to Carbondale for comment. The Carbondale Planning and Zoning Commission reviewed the sketch plan at their July 13th meeting.

RESCUE July 5, 2000 Mark Bean Garfield County Planner 109 Eighth Street, Suite 303 Glenwood Springs, CO 81601 RE: Roaring Fork Preserve Subdivision, Sketch Plan Dear Mark: I have reviewed the skach plan for the proposed Roaring Fork Preserve Subdivision. I would offer the following comments: Access -he propos"d access to the subdivision including the proposed road wi&hs and the cul-de-sac design appears to be adequate for emergency vehicles. Driveways should be constructed in accordance with county road standards. Water Supplv The proposal indicates that either a storage pond for fire protection water will be constructed or the residences will be required to have automalic fire sprinklers installed. Consi dering the distance between the proposed residences, it would be impractical for a single water storage source to adequately serve all the residences. Automatic fire sprinklers would better serve the residences in this case. It would be prefera ble to have a storage Pond or other source as a backup to the automatic fire sprinklers' If a pond is used for water storage, it should be designed and constructed to allow for year around access and use by fire apparatus and have a minimum usable capacity of 30,000 gallotx' Immc't Feos The development is subject to impact fees adopted by the District for the thirteen proposed residential units. The developer will be required to enter into an agreement with the D istrict for the payment of development impact fees. This payment is due prior to the recording ofthe final plat. Fees are based upon the per lot impact fee adopted by the D Please contact me ifyou have any questions. Bill Gavette istrict at the time the agreement is executed.

Division 5, W. District 38 Dear Mr. Bean: We have reviewed the additional information provided for the above referenced proposal to subdivide a parcel of 90.03 acres into nine lots, with nine single-family dwellings and four accessory dwellings. Water is to be provided through individual wells for each lot pursuant to a contract with the Basalt Water Conservancy District (the District) and the District's temporary substitute water supply plan. Sewage is to be through individual septic and leach field systems. The applicant submitted nine well permit applications to the Division of Water Resources, which were returned on February 9, 2001 for additional documentation of the replacement water source. Although the applicant provided a copy of an approved water allotment contract that was granted by the District, the annual amount specified in this contract is insufficient to make replacements for the proposed uses. Further, to be considered a legally reliable source of water, the wells must ultimately be included in a court approved augmentation plan, since there is no guarantee that a temporary substitute water supply plan will be renewed. The pump test completed by Samuelson Pump Company on January 3 and 4, 2001, indicates that the #8 well produced 10-15 gallons per minute over a 24-hour period. lf the additional wells have similar production rates and adequate storage capacities, the water supply should be physically adequate. Based on the above, it is our opinion, pursuant to CRS 30-28-136( 1 Xh)(l), that the proposed water supply is physicaiiy aciequate, howevei' matcrial injury v,,i!l occur to dec!'eed water rights unless the applicant obtains and maintains valid well permits for the proposed wells pursuant to a court approved plan for augmentation or pursuant to the District's temporary substitute supply plan. lf you or the applicant has any questions concerning this matter, please contact Kimberly Willson of this office for assistance.

At the planning meeting last weet it sounded as if most of my cornmants were going to be implemurted. Howwer, I hrve two items that I would like to eqhasize. The first deals with some of the building envelopes. It would be beneficial to wildlife to plaoe the Ssllding envelopes for lots I and 2 as close to lots 3 and 4 as possible. This will he$ to maximize the buffer along the river and facilfuate the movement of wildlife along this corridor. The other item deals with tie storage of hay on the property. For those units, which will be allowed to have livestocl all hay *ored outside should be fenced with 8-foot high game prooff€ncing. This fencing should be erected at ttre oumers' expense to prevent loss by deer or elk. Unprotected haystacks could serve as an €nticement to deer wintering on the Crown, as well as the resident deer itr the area. Thank you for the opportunity to comment.

At your request and in accordance to Senate Bill 35 (1972) this offrce has reviewed the materials submitted and conducted a site inspection on March 31, 2001. The materials submitted include a Preliminary Plan Application dated January 23, 2OOl. The application includes a preliminary geotechnical report that includes percolation tests. As u,e understand ISDS are proposed for this development. The CGS had recently reviewed an adjacent property called the Mayfly Bend Subdivision. Many ofthe conditions are our observations are similar. Please consider our observations and recommendations in your review of this land use application. The site is on the floor ofthe Roaring Fork River Valley east ofCarbondale. The eastem portion of the property extends to the river. The site is relatively flat with several irrigation channels. The site is underlain by river terrace deposits of gravel and cobble that has been deposited over bedrock of the Eagle Valley Evaporite. This formation contains evaporitic minerals that, in the presence of fiesh water, dissolve. We have read the Preliminary Geotechnical Study and generally concur with their content. River terrace alluvium generally provides excellent bearing capacity for foundations. The potential impacts we see to this development will be wetland impacts, very shallow ground water, possible hydrostatic head from confining soil cover, and very rapid percolation rates in the gravel and cobble. None of these conditions would preclude the development as intended. As stated in the geotech report, basements should be avoided. Engineered mounded septic systems will need to be designed for the residences at this development because of the fast percolation rates, the high ground water, and proximity to the river. Consideration should be made of a centralized wastewater treatment plant to serve the new developments in this area. DEPARTMENT OF NAII.IRAL RESOURCES EillOwens Crc8 t. W.lcher Exeolive Dir€ctor Micha€l B. Lons Divirion Dircctor Vicki Cowan Srate C€ologi( As mentioned in the geotech report, bedrock dissolution can result in the formation of sinkholes. We generally concur with the risk assessment made. We could also find no features on t}re property that was indicative of subsidence. Care should be given, though. The braided nature ofthe terrace surface tends to create shallow troughs and ridges that could obscure smaller or subtle subsidence features. While HP Geotech or CGS is not aware of any sinkholes in the area of this development, foundation excavations should be inspected by the geotechnical consultant prior to construction. Provided site specific investigations and loundation designs are conducted and our concems above are addressed, this office has no other concems with the development as planned.

Since I am past your deadline, I will revie$. in bold italics. thc applicant's response to my original comnents on the Sketch Plan (7/5/Oo). based on the information that is on hand. l. Request the applicant to conduct a noxious weed sun'ey for the w€eds listed on Garfield County's Noxious We€d List (enclosed). There is a general noxious weed survqt in the l{eilands Report. fhe report dales general vegetative characteristics for euch loL Canada arul bull thistle are found on some of the lots. I did not Jind any menlion of plumeless thistle in the report. Plumeless thinle k very common in this aret and my guess is thul it is prevalent on this property. 2. Ask then Io submit a ilritten Weed Managernenl Plan provide for the rnanagement of ar1- listed weeds located on lhe propertl-. Particular attention should be given to any irrigation ditches located on the property. The Weed Management Plan should designate responsibilit-r- for weed control on road ROW's. 3. Revegetal.ion-Plumeless thistle is fairly prevalent in this general area. Withoul proper rel'egetation of any new roadcuts or utility right-of-rvays, the lhistle witl spread quickly along Itre new ROW'S and infest the hay fields and pastures. It is recomnrended that the applicant. US West, KN Energy, and Holy Cross Electric submit a detailed revegetation plan for all proposed disturbances. The revegetation plan should include: Proposed seed mix and rate. List common and scientific name ofplant species Planting schedule and methods to be used. Itet E #2 and #3: Weed management is discussed in the covenants. Again, the corenqnts are speciJic to the lot ovnets.

Garfield County Revegetation Guidelines From the Garfield County Noxious Weed Management Plan {.06 Revegetationand Rehabilitation: A crucial part of any weed management plan is the reintroduction of site appropriate vegetation. Establishing a desirable plant community after noxious weeds have been removed from a highly infested area requires timely cultivation and reseeding. Since the seeds from noxious weeds may lay dormant for many years. removing all visible signs of the noxious weeds does not ensure against their return. Revegetation can help prevent the germination of weed seeds. It is important to inspect the land regularly to identify and treat small, new infestations. For proper reclamation, managed irrigation of dry areas, fertilization, and reseeding are essential to establish desirable plant communities. Native plants are most appropriate when the goal is restoration (trying to restore native habitat). Weed-free seeds of native Colorado grasses, wildflowers or plant species appropriate to the site may be purchased, but the best source for seeds is from native species that grow in the immediate vicinity of the infestation. They will be best adapted to local conditions and will help maintain local integrity and genetic viability, Using native plants or seeds to reclaim disturbed land reduces degradation ofnative ecosystems, reduces the need for herbicides and conserves water resources. Native plants will provide a broad biological diversity and help keep Colorado looking like Colorado with a unique regional landscape that sets us apart from other areas ofthe country. When the goal is reclamation (reseeding for quick ground cover establishment or erosion control), it may be appropriate to use introduced, non-aggressive grasses and forbs. Contact the Natural Resources Conservation Service or Colorado State University Cooperative Extension for seeding recommendations. The Native Plant Revegetation Guide .fbr (blctrado, published by the Colorado State Parks Natural Areas Program, is an excellent guide for native plant reseeding. Contact the Garfield County Vegetation Management oftice for further information on this material. STRATEGIES: . Study all vegetation in the area and surrounding areas. o Preserve plant species native to Colorado. o Test the soil for pH balance. Try to retain and utilize as much on-site topsoil as possible. o Select a predominant species that is appropriate to the site. Then choose a few complimentary species to provide a balanced plant community. . Choose plants that are healthy, vigorous and pest free. o Use weed-free seeds. Use non-hybrid seeds. Avoid commercial seedpackets containing exotic plant species . Choose plants that are horticulturally appropriate, i.e. plant species that are adaptable to climate, soil and topographical conditions ofthe designated area. . Consider the use of water, its availability and the vegetative requirements. . To landscape for wildlife, choose native plants that provide cover, forage, browse, seeds for birds and rodents, and shade. o Be site-specific, revegetation strategies may vary for small lots, farms, ranches or construction sites. o Establish a vegetative cover that is diverse, effective and long lasting, capable of self- regeneration. .

The sketch plan appears to show more trees on the site than actual field conditions. lt also appears that the existing potato cellar is not indicated on the sketch plan. The addition of the four accessory dwelling units would resuh in slightly higher density than the Garfield County Comprehensive Plan recommendation for the area.

At your request and in accordance to Senate Bill 35 (1972) this office has reviewed the materials submitted and conducted a site inspection on March 31, 2001. The materials submitted include a Preliminary Plan Application dated January 23, 2001. The application includes a preliminary geotechnical report that includes percolation tests. As we understand ISDS are proposed for this development. The CGS had recently reviewed an adjacent property called the Mayfly Bend Subdivision. Many ofthe conditions are our observations are similar. Please consider our observations and recommendations in your review of this land use application. The site is on the floor of the Roaring Fork River Valley east of Carbondale. The eastem portion of the property extends to the river. The site is relatively flat with several irrigation channels. The site is underlain by river terrace deposits of gravel and cobble that has been deposited over bedrock ofthe Eagle Valley Evaporite. This formation contains evaporitic minerals that, in the presence of fresh water, dissolve. We have read the Preliminary Geotechnical Study and generally concur with their content. River terrace alluvium generally provides excellent bearing capacity for foundations. The potential impacts we see to this development will be wetland impacts, very shallow ground water, possible hydrostatic head from confining soil cover, and very rapid percolation rates in the gravel and cobble. None of these conditions would preclude the development as intended. As stated in the geotech report, basements should be avoided. Engineered mounded septic systems will need to be designed for the residences at this development because of the fast percolation rates, the high ground water, and proximity to the river. Consideration should be made of a centralized wastewater trearnent plant to serve the new developments in this area. DEPABTMENT OF NATI-IRAL RESOURCES EillOw€ns Cre8 t. Walchcr treculive Onector Michael 8.1-on8 Division Diredor VicliCo\ran Si.c C€olo8isr and Dir€ctor 7b- Mr. Mark Bean Garfield County Departrnent Building and Planning 109 8t Street, Suite 303 Glenwood Springs, CO 81601 As mentioned in the geotech report, bedrock dissolution can result in the formation of sinkholes. We generally concur with the risk assessment made. We could also find no features on the property that was indicative of subsidence. Care should be given, though. The braided nature of t}te terrace surface tends to create shallow troughs and ridges that could obscure smaller or subtle subsidence features. while HP Geotech or cGS is not aware of any sinkholes in the area ofthis development, foundation excavations should be inspected by the geotechnical consultant prior to construction. Provided site specific investigations and foundation desigas are conducted and our concems above are addressed, this olfice has no other concems with the development as planned.

The pL[pose of this letter is to address several concems we have regarding the proliminary plan for the Roaring Fork Preservatiofl Subdivision. I regrEt the lateness of this submission, but did not rcceivo the Project Iuformatioa and Staff Comments until this morrring. The 100 Road Cattle Company, 1265 County Road, 100, Carbondale, Colorado 81623, owns qrproximately 43 acrcs adjacent to and to the west olthe proposed srrbdivision. More speoifically: L We strongly ohject to allowing r density of less than onc building per 10 acres' White this area to the east of the town of Carbondale is presently served by an adequate roa( CR 100, this road is also tbe only cast/west access to the tonrn other than off of Route 82 to the uofihwest. Increasing the density in this area will create, we believe, a need for road improvements and, perhaps, additional .ingress and egress for the area. 2. If thc subdivision plan, with the ohanges recommcnded by stafi is app,roved wc would urge that a requirement bo included that any new power lines be buried and that oristing power lines bc buried at the expense of individual property owners within a reasonable pcriod of timc. 3. We considered staff comments and other infrrmation providod with regard to sewer and septic coruiderations. We urge the Commission to give careftrl consideration to the rese(vations expressed by staff. We strongly urge that a condition for approval be a roquiremant to monjtor for purity, with reasonable enforcernent provisions. ll25Jr79-01rll 4B- March 27.2001 Prge 2 4. We would request tJrat if the projc,ct is approvd it can contain covena[ts or restrictions applicable to any owner in the subdivision for arutual weed control inspection with su-fficient power in the proper authorilr to enforce weed control, 5. Fiually, we notc that there has beeu no hydrorogist evaluation, nor has the Commission received comments from thc colorado Geological Survey. we noted the staffs reference that "engineers" fccl flre existing natural drainage routes n'ill suffioo.
