SCHENK DAN KERST wtLLtAM J. DEwtNTER, lll Garfield County DeparEment of Development Planning Divislon Attention:Mr. Mark Bean 2014 Blake Avenue Glenwood Springs, C0 81601 RE: J-Mar EstaEes Dear Mark: I enclose herewith a copy of the completed Water Allotment Contract between the West Divide Water Conservancy District and Gary R. Sheveland. This cont.ract will be the basis upon which we will obtain well permlts for the lots in the proposed J-Mar Estates Subdivj-sion. You might noEe a discrepancy between the 6 acre feet of water reflected on the first page of the contract and the 9 acre feet reflected as the annual total of water needed on the application attached to the contract as Exhibit "B". The 9 acre foot total was based upon the original application for lB lots and was accordingly reduced to 6 acre feet when the number of lots requested was reduced to 12. It is my understanding of the agree- ment betl^7een the West Divide Water Conservancy District and Lhe SEate Engineer, that Mr. Sheveland can be assured of well permits for the 1ots. However, well permit applications can noE be filed until the specific lots are identifiable. Will Lhe submitEal of the enclosed contract, be sufficient to proceed with Garyrs subdivision application or will aCditj-onal confirmati-on from the State Engineer be needed? If so, what. is the procedure to provide you that j-nformation? Please give me a call so that we can discuss this matter further. Yours very tru1y, DK/reh Enc.

An existing irrigation ditch roughly para1le1s the southern boundarly of the developnrent to the south. Ttre najoriQr of the site consists of agricultural land previously cultivated with the exceptionof the southwest corner of the developnent (Parcel 9 and portions of Parcels 8 and 10), v/hich is vegetated priararily in sage, grasses, weeds and scattered brush and Parcel 1, which is covered in tall grass and scattered decedidr.rous trees. Several one to tuo story wcod frane residential structures are located on the properties adjoining the developnent to the northeast. Ttre structures obserred are of fairly recent construction and generally jn good cordition, shcwing no apparant indication of for:ndation d.istress.

This deep, well drained, moderaLely sloping to hi1Iy soil is on alluvial fans and valley sideslopes. It lormed in alluvium from Green River shale and sandsLone. ELevation ranges from 5,000 to 6,500 feet. The average annual precipitation is about 13 inches, the average annuaL air temper- ature is about 48 degreeS F., and the avenage frost-free period is about I25 days. Typically, Lhe surface layer is light gray channery loam abou! lL inches thick. The subsurface layer is very pale brown slony roam about 7 inches thick. The undenlying layer is very pale brown exLremely sLony and channery loam that extends to a depth of more than 60 inches. Included with this soil in mapping are small areas of Arvada and rldefonso soi]s r.rhich make up 10 to 15 percent of the mapping uniL. Arva,la soil is found on the moderaLely sloping areas and rldefonso soil is on the sLeeper portion of the }andscape. Permeabitiby of t,he Nlhirl soil is rapid. Effective rooting depth is 30 to ll0 inches. Available water capacity is low. surface runoff is slow and the erosion hazard is high. This soir is used mainly for livestock grazing and wirdtife habilat. The native vegetat,ion on this soil is mainly bluebunch wheat- grass, fndian ricegrass, serviceberry, and big sagebrush. 59DE-Nihj.11 channery loam When the range condition deLeriorates, forbs and woody shrubs j-ncrease. l.Jhen Lhe range is in poor condition, undesirable weeds and annual plants are numerous. Proper grazing management maintains and improves range condition. Seeding is a good practice on slopes of less than 15 percent if the range is in poor condition. Careful selection of areas J-s necessary because of stoniness and shallow depth to bedrock. Suitable plants for seeding are crested wheatgrass, western wheatgrass, and Russian wildrye. For successful seedings, a good practice is to prepare a seedbed and drill the seed. A reduction in brush on slopes less than 15 percent improves deleriorated sites. Care is required not to destroy desirable shrubs. lnlildlife using this soil for habit,at include mule deer, cotton- tail rabbit, chukar, and squi.rrel. The potenLial community development of Nihill soil is limited by steep slopes, sLone and channery conLent. Community sewage facilities are needed if population density increases.

Elevation rairges from 5r1OO to 61200 feet. fhe average arueual precipitation is about 12 inches, the average annual air temperature is about l+B degrees I., and the avera€e frost-free period is about 120 days. Typically, the surface layer is pale brown loam about J inches thick. The subsoil is brown silty clay 1oa.m about 1[ inches thick. The substratum is light brown or brown silty clay Ioam that extend.s to a depth of 50 inehes or more. Included. with this soil in mapping are smal1 areas of Limon, Kimt He1d.t, and. Uann soj-1s all on similar slopes. Also some areas high in silt are included.. Pe:meability of the Arvada soil is mod.erately slow. Effective rooting d.epth is 50 j.nches or more. Available water capacity is high. Organic natter content in the surface is }ow. Surface runoff is med.ium and the erosion hazard. is moderate. This soil i.s used. mainly for wildlife habitat, limited. livestock grazing, and some irrigated. fanning. Irrigation methods suitable for this soil are borders, furrows, and corrugations. Leaching is a requirement to remove excess sal"ts when this soil is imigatecl. Comrnercial fertilizers containing sul-fates and. carbonates are preferred to obtain reasonable prod.uction of alfalfa, corn, and small grains.

Proper grazing rnanagernent maintains and improves range condition. Seed.ing is advisable if the range is in poor conclition. Suitable plants for seecting are western wheatgrass, alka1i sacaton, ancl taI1 wheatgrass. For successfuf- seed.ing, a good. practice i.s to prepare a seed.bed. ancl d.ri11 the seed. Teruporary irrigation of a new seed.ing may be requi.red. for successful establishment. Red.uction in bmsh improves deteriorated. rarge sites, provid.ed there is adequate grass und.erstory.

Storm water from Drainage Basin A will collect in the drainage ditch along the east side of Giomi Lane and be deposited into the drainage ditch along the south side of County Road No. 346. St&6m water from Drainage Basj-n B wiII colLect in the drainage ditch along Giomi Lane ahd also be deposj.ted in the drainage ditch along the south side of County Road No. 346. Drainage Basin C will drain into the Rising Sun Ditch prior to its inter- sectj.on with County Road No. 346. The Rising Sun Dithc will also collect the storm water drai.nage from Basin D--- a large portion of this drai.nage being carried by the existing irrigation ditch at the south boundary line of il-Mar Estates. The existing entrance of Giomi Lane has a /9,, C.M.p. culvert. It is recommended that this culvert be replaced with a Zy' " C.M.P. culvert in order to carry the 26.0 cfs from Drainage Basin A. At the future Giomi Lane intersection a fl"c.M.P. curvert is rTecommended to carry the 50.4 cfs. of Drainage Basins A & B.

Box 1322 Rifle, @ 8f650 Dear Sir: As requested, we have corq>leted a paventent desiga-r for the proposed extension of Giorni Lane in J-Ma-r Estates. tr'ie previously perforned a preliminarlz soil and for:ndation investigation for the subject site issued r:nder our Job Nunber 25,366 dated April B, 1983. Soil Conditions: A sanple of the subgrade material was obtained along @t-of-raiay near the location of or.rr original test hole 3. Ttre sanple was taken 6 lo 12 j-nches belo,v tLre existing ground si:rface. the sanple obta.ined consisted of sandy clays similar to those encountered in the prelinr-inaqz investigation. The results of laboratory ccnpaction, CBR and Index Properties tests are presented in Fign:res 1 through 3. The soils obtajled classify as A-6 withr a group index of 14, in accordance with the Anrerican Association of State Highway and Transportation Officials (AA,SIfl'O Classification). Ttre CBR value at 958 of ttre standard Proctor density is 3.5?. This value was used for design of the flexjble pavement section. Pavenent .Design: \pical daily traffic was assuned to be less than 750 @ with a verlz snall anprint of tmck traffic. An 18 kip eguivalent daily Ioad application (EDIA) cf 5 was assuned in the desigrn. Ttre pavanrent section is based on laboratoq/ test results and the assrmed traffic loadings. A pavenent consistirg <.:f 3 inches of asphalt and 6 inches of aggregate base crcurse is reonrrended. An alternative pavenent section consisting of 5 inches of fu11 depth asphalt may be used. the asphalt pa.venent should consist of a bitr-rriinous plant rnix ccnposed of a nrixture of aggregate and bitr-minous material, which meets the requirenents of a job nLix formula established by a gualified engineer, and the appropriate AASFII\) specifications. The base course rnaterial- should have a nrinimtm R-Value of 84. OFFICES CASPER . COLORADO SPRINGS. DENVER. SALT LAKE CITY Gary Sheveland JuIy 29, 1983 Page TVo Prior to pJ.acing the pavonent section the entire subgrade should be scarified to a depth of B j-nches, mristened to opti:nun moisture content and ccnpacted to 95% of the nraxjmr.u'n standard Proctor density. The pavenent subgrade should be proof-ro1led with a heavily Ioaded pneunatic tired vehicle. Areas which deform excessively r:nder the wheel load shoul-d be rsncved and replaced prior to pa.ving. Srrbgrade, fill and pavernent nraterial should be corq:acted to at least 95% of the standard Proctor density at a noistr:re content near optirnr-un. The coll-ection ard diversion of surface drainage away from pavd areas is extrernely rmpo*tant to the satisfactory performance of the pavanent, particularly in .1reas such as this where natwal soils have a l-q,r to moderate collapse potential. The design of sr:rface drainage should be carefully considered to rgncve all water frcxn paved areas. Pavqnent Alternative: An alternative to asphaltic concrete sr:rfacing isffi subsequent chip seal applied over a corqrcsite section consisting of a rninimrrn of 3 inches of aggregate base course and 9 inches of granular subbase similar to that specified by Garfield County. Subgrade preparation and conpaction should be as described a-bove. It should be noted that this alternative ccrrposite section isof lesser structural capacity than ttre asphaltic section reccnnended above. This alternative will require higher maintenance and periodic replacement or repair of the chip seal sr:rface ard/or base materials. Lirnitations: This report has been prepared in accordance with generallye@-Foil and foundation engineerGg practices in this area for use by the client for desigar pur?oses. The conclusions and reconmendations suhnitted in ttris re6rcrt are based qrcn the data obtained frcxn the sanple t:ken in the proposed alignnent in conjunction withr the data presented in or:r preliminary report. The nature and extent of rzariations across the site rnay not beccxne evident until grading is performed. If during construction fill, soil, rock and water conditions appear different frcxn those described herein, tLris office shoutd be notified at once so re-evaluation of the reconmendations may be made.
