APPLICANT: Gaye Leo ENGINEER: Colorado River Engineering, Western Water Consulting, Inc. LOCATION: Parcel lies on Taughenbaugh Mesa, southwest of Rifle. Section 20, Township 6 South, Range 93 West WATER: One shared existing well SEWER: Individual sewage disposal systems (ISDS) ACCESS: CR 320 (parcels 2 & 3) and CR 321 (parcel 1) EXISTING ZONING: A/R/RD ADJACENT ZONING: A/R/RD, with O/S to the southwest I. RELATIONSHIP TO THE COMPREHENSIVE PLAN According to the Garfield County Comprehensive Plan of 1984, this site lies in "District C — Rural Areas / Minor Environmental Constraints". District C is described as having a moderate ability to absorb growth. This district includes all lands which are not serviceable from an existing municipality or subdivision with water or sewer services. Since this site is located within one (1) mile of District A it is considered to be a transitional area between rural and urban densities. The suggested density is no more than one (1) dwelling unit per two (2) acres, subject to the mitigation of environmental constraints. II. PROJECT INFORMATION A. Site Description: Taughenbaugh Mesa overlooks the Colorado River to the North and is bordered on the west and east by Beaver Creek and Helmer Gulch. BLM land exists to the south of the property. The site slopes about 6% from the highpoint at the southwest Page 1 of 12 • • down to the northeast. The site is gently rolling pastureland historically irrigated for hay crops. The dominant vegetation is grass and sagebrush. Lot 1 is currrently occupied by a single family home, which received a certificate of occupancy on 6/1/00. It is accessed via a gravel driveway to CR 321. B. Development Proposal: The applicant is proposing to divide a fifty-one (51) acre parcel into three (3) single family lots: parcels 1, 2, & 3. The location and size (but not the total # of lots) of the proposed lots has changed from the sketch plan proposal. The sketch plan proposed one 5 acre lot at the far northwestern corner of the property, to be accessed via County Road 321, and one 10 acre parcel along County Road 320. The remainder parcel was about 36 acres in size. The preliminary plan now proposes two 5 acre lots along CR 320, and a remainder parcel of 41 acres to be accessed via CR 321. C. Adjacent Land Uses: Agricultural and residential land uses surround the site. III. REVIEW AGENCY AND OTHER COMMENTS: Referrals of the site plan were sent to the following: A. City of Rifle: On 9/25/00 Pat Hopkins, Rifle Planning Director, said in a telephone conversation with Garfield County Planning Staff that the Leo preliminary plan had been discussed by City Council and they have no concerns or comments. B. Bookcliff Soil Conservation District: No reply received. C. RE -2 School District: Stated on 8/28/00 "no concerns". D. Colorado Geological Survey: See letter dated 9/29/00, page 15 . Provided site specific investigations and foundation designs are conducted, this office has no concerns with this development as planned. E. Garfield County Road & Bridge: Jake Mall called on 8/29/00 to say that the plan appears "fine". An access permit has been issued for one driveway (to serve lots 2 & 3) on CR 320. It will be built with a 10' collar and to standard driveway specifications. F. Rifle Fire Protection District: See letter dated 9/26/00, page j4". Makes some specific recommendations concerning removal of vegetation, road construction, and posting of addresses. Also notes that the water supply in the area has limited fire flow capabilities. Although the proposal meets the District's minimum requirement of having an approved water source within 2 miles, fire flow capabilities would likely not be available to extinguish a fully involved structure fire. G. Garfield County Public Health Nurse: See referral sheet, dated 8/8/00, pagel5' - , hnd letter dated 10/23/00, page )--'' Does not state any opposition to approval of the plan. H. Garfield County Engineer: See referral sheet, dated 9/5/00, page / c and Western Water Consulting letter, page 13The County Engineer noted that Chris Manera's professional engineer's license had become inactive and needed to get it re -installed. She recommended denial due to limited water supplies for fire protection. (Staff comment: Chris Manera addressed the licensing issue by a peer review. Western Water Consulting, Inc. (license #24034) has reviewed, approved, and stamped all necessary Page 2 of 12 . • documents. Since the Rifle Fire Protection District has stated that the application meets minimum requirements, the County Engineer stated in a telephone conversation on 9/27/00 that she is no longer opposed to approval of the application.) I. Colorado Div. of Water Resources: See letter dated 9/12/00, page (S . The State Engineer notes that, "With adequate storage capacity this well should provide an adequate supply for the proposed use". It is the opinion of the State Engineer's Office that, "... the proposed water supply will not cause material injury to decreed water rights, and is physically adequate, so long as the use of the Taughenbaugh Ditch water rights is not expanded". J. Colorado Div. of Wildlife: v .SP. _ J2 CA / / "c e K. Garfield County Sheriff: Returned the application without any comment. L. Garfield County Vegetation Management: No reply was received. M. Garfield County Housing Authority: See referral sheet, dated 8/25/00, page, -)14 Encourages the developer to keep sale prices affordable and remind her of the need for affordable rentals. IV. STAFF COMMENTS A. Comprehensive Plan: The proposed density is one (1) dwelling unit per seventeen (17) acres, which is much less dense than the Comp Plan's suggested density of one (1) dwelling unit per two (2) acres. The proposal appears to generally conform to the Comp Plan. B. Zoning: A single family dwelling is a use by right in the A/R/RD zone district. Accessory uses are allowed if they are agriculturally related uses. C. Subdivision: The lot design appears to generally meet the standards set forth in the Subdivision Regulations. D. Soils/Topography: Colorado River Engineering, Inc. (CRE), and Western Water Consulting, Inc. (WWC), have both concluded that no hazards or soil constraints exist that would impair the development of the property. However, the possible existence of localized areas of clay -loam lenses with shrink/swell properties warrants future considerations. They recommend that site specific soil samples be collected for each building footprint prior to building permit issuance for parcels 2 & 3. A geotechnical engineer should examine the soils and prepare an engineered foundation. Radiation is not known to be associated with the sedimentary type bedrock formation which underlies the property. The U.S. Geological Survey has stated that if site specific investigations and foundation designs are conducted, they have no concerns with the development. As long as the need for engineered foundations is included as a condition of approval, in Page 3 of 12 • • the subdivision covenants, and as a plat note, staff does not have any geology related concerns. E. Road/Access: Lot 1 (the 41 acre parcel) will be accessed via an existing access easement to CR 321. The two newly created lots (2 & 3) will share a 30' wide, 70' long point of access to CR 320. Plat notes #8 and #12 discuss the "primitive residential" standard and the maintenance responsibilities of the road. According to the subdivision regulations, the road servicing Parcels 2 & 3 must meet the "primitive residential" standard in Section 9:00 of the Subdivision Regulations. This standard calls for a minimum thirty (30') foot wide access with a single lane at least twelve (12') feet in width with a native surface, and a hammerhead turnaround, amongst other things. Plat note #12 must be amended to replace "property owners' responsibility" with "Homeowner Association's responsibility". The application states that road access costs will be assumed by the lot owner. The applicant should understand all improvements required by the Subdivision Regulations are her cost responsibility and shall be installed according to the Subdivision Improvements Agreement (SIA) and secured by cash or a letter of credit, as is customary and required by the Subdivision Regulations (see section 5:31). Jake Mall, of the Garfield County Road and Bridge Department, called on 8/29/00 to say that the plan appears "fine" . An access permit was issued for one driveway (to serve lots 2 & 3) on CR 320. F. Fire Protection: The application states: "Rifle Fire Protection guidelines are to be reviewed and compliance with suggested fire safety provisions are the individual lot owner's responsibility. This proposal meets all minimum requirements of the Rifle Fire Protection District". Plat note # 9 lists some fire protection comments. The site is located in the Rifle Fire Protection District (RFPD). The RFPD noted some specific recommendations concerning removal of vegetation, road construction, and posting of addresses. The water supply in the area has limited fire flow capabilities. Although the proposal meets the District's minimum requirement of having an approved water source within 2 miles, fire flow ca abilities would likely not be available to extinguish a fully involved structure fire " vt k -I) to . ice ' nk_4"" k /)- No water storage has been proposed for fire fighting purposes. For this reason, the County Engineer originally recommended denial of the application. However, since the Rifle Fire Protection District has stated that the application meets minimum requirements, the County Engineer stated in a telephone conversation on 9/27/00 that she is no longer opposed to approval of the application. Page 4 of 12 • • None of the recommendations made by the fire district have been included in the covenants. It will be very difficult for each individual lot owner comply with suggested safety provisions if they do not know what they are. While plat note #9 attempts to address fire issues, it needs to closely reflect the Rifle Fire District's language in their letter dated 9/26/00. G. Domestic Water System / Irrigation: The household and domestic animal water supply for the three lots is to be provided by a shared well. The well is an existing structure serving the existing residence on the 41 acre parcel. Well permit #221943 was issued as the only well on a 51 acre tract of land and is limited to a pumping rate of 15 gpm. The use of the well water is limited to ordinary household purposes inside 3 single family dwellings, the irrigation of not more than 1 acre of home gardens and lawns, and the watering of domestic animals. The well was pump tested on April 25th, 2000, following the winter period and prior to irrigation water being diverted on to the mesa (typically when water levels are lowest). The initial water level was measured at a depth of 89 feet and provides approx. 41 feet of drawdown capability (130' total depth, 89' static level). The water level dropped about 2 feet within the 1 1/2 hours and stabilized at 2 '/4 feet of drawdown after 21 hours. The pump test was terminated after 24 hours and recovery data was collected for an additional 24 hour period. The well recovered to the initial static level. It is Colorado River Engineering's (CRE's) and Western Water Consulting's (WWC's) opinion that the well yield (in excess of 7 gpm) is capable of meeting the peak average monthly demand of 1.7 gpm for the subdivision. ,t,A The water quality was tested for bacteria and nitrate/nitrite and found to be within the legablimits. However, it was not tested for dissolved solids. The water must be tested fordissolved solids prior to approval by the Board of County Commissioners. If treatment is necessary, the proposed method of treatment shall be submitted to County Staff and the Board in sufficient time for review prior to approval of the preliminary plan. (Update: This information has been submitted. The dissolved solids measured 560 mg/l, which is in keeping with the amount found in other municipal sources in the area.) CRE and WWC state in the application, "The water system will be comprised of the shared well delivering water to individual water storage tanks at each lot. The existing pump has the power to deliver water to all the lots. Each supply line to the lots should have a minimum diameter of 1 -inch to minimize friction losses. The construction of the delivery lines, tank, and tank level controls will be the responsibility of each lot owner". However, this is not consistent with the Subdivsion requirements. It is the applicant's responsibility to install the required water system improvements. In addition, Section 9:53 requires the following: Page 5 of 12 on �� A Central water systems shall be designed by an engineer qualified to design water systems and be a registered professional engineer licensed by the State of Colorado. Central water and treatment and storage facilities shall be approved by the Colorado Department of Health. All lines in a central water system should be looped, with no dead ends included in the system. Where dead ends are proposed for cul-de-sacs, there will either be a fire hydrant or blow -off valve at the end of the line. The application contains a "Declaration of covenants, well sharing, and irrigation water use agreement". applicant does not intend to form an Homeowner's Association (HOA) but rather inten to make each lot owner share responsibility for installation and 1_o ._._--.41-,14--L maintenance of the improvements_ However, this is contrary to the Subdivsion '4e," regulations. Section 4:91 (B) (1) requires tha c ' - m-4- U L AA -c 1�A �� ,Q If a central supply and distribution system is to be rovided, a general description of tife A41 14 - system, as designed by a Colorado registered engineer. In addition: 1. Nature of the legal entity which will own and operate the water system; and d.x',�Yrt 2. Proposed method of financing the water system. U�`� I_DlaA :) An incorporated HOA has the ability to levy fees, own improvements, and has a separate or' st enforcement capability. Individual lot owners are not "a legal entity" and are much less W2:0, likely and able to follow through with these responsibilities than an HOA.U►Y'uZ Irrigation water is to be supplied through the use of 0.52 cfs of the Taughenbaugh ditch, which has been decreed in District Court for Water Division 5. Lots 2 & 3 are to be limited to 3,000 square feet of lawn and garden irrigation with 0.026 cfs for each lot. The owner of Lot 1 shall retain ownership of the remaining 0.468 cfs and may irrigate as much of this lot as is practicable. CRE and WWC state that the well will provide a reliable source of water supply based on the estimated demand level and available physical supply of groundwater. Since the instantaneous peak demands from the parcels could exceed 15 gpm, they recommend that each lot provide a small storage tank (250 to 500 gallons) and booster pump to meet peak demands. They further note that the irrigation water right is "junior in priority" and is typically administratively curtailed in most years following the peak runoff months of Beaver Creek, and a plat note should disclose this information (said note has been included on the plat). The State Engineer notes that, "With adequate storage capacity this well should provide an adequate supply for the proposed use". He also notes that the use of the 0.52 cfs of the Taughenbaugh Ditch must be limited to the historic amount. If any increase occurs, a change of water rights application must be filed with, and approved by, the water court. He further notes a typograhical error (0.26 cfs verses 0.026 cfs), and a needed change to the covenants: the "stockwatering use" must be changed to the "watering of domestic Page 6 of 12 • • animals". It is the opinion of the State Engineer's Office that, "...the proposed water supply will not cause material injury to decreed water rights, and is physically adequate, so long as the use of the Taughenbaugh Ditch water rights is not expanded". Wastewater: Individual sewage disposal systems (ISDS) are proposed for each new lot. The existing home (on Lot 1) has wastewater treated by a septic tank and adsorption field. This system was permitted by the Garfield County Sanitation Department based on percolation tests that averaged 7 minutes per inch. It is CRE's and WWC's opinion that septic and adsorption fields can also be utilized on the two new lots. The bedrock and water table are at depths of 80+ feet and will not affect the operation of ISDS. They further emphasize that proper care and maintenance and monitoring by the HOA is essential to assure proper operation. Section 4:92 E (of the Garfield County Subdivision Regulations) requires that a proposed management plan for the operation and maintenance of on-site systems be provided. While the application contains CRE's attachment Pipeline (Fall 1999, Vol. 6, No. 4, prepared by the National Small Flows Clearinghouse) concerning ISDS maintenance, the applicant failed to address this issue in the covenants and/or include Pipeline as an attachment to the covenants. The covenants need to be amended accordingly. Drainage: CRE and WWC state that the property is not in any floodplains or subject to localized flooding. A comparison of the existing conditions versus the developed conditions indicates there will not be any increase in historic runoff flow to downstream property owners. An 18" diameter culvert is recommended at the access entrance to CR 320. The Garfield County Subdivsion Regulations require the following (section 9:44): All culverts shall be designed such that the exposed ends are protected by encasement in concrete or extended a minimum of three feet (3) beyond the driving surface on each side. Culverts, drainage pipes and bridges shall be designed and constructed in accordance with AASHO recommendations for an H-20 live load. The applicant should understand that installation of the necessary drainage features is her cost responsibility. J. Wildlife: The application states that the DOW has been consulted regarding migration patterns. It states, "The existing migration patterns and habitat will remain undisturbed" but the "existing migration patterns" are not identified anywhere within the application. No evidence of such consultation has been included, nor are any migration corridors identified. It states that fencing has been designed to be "elk friendly" and that a wide sage brush ribbon on Lot 1 serves as home to local deer and elk. However, the covenants do not specify any fencing requirements or need to preserve wildlife habitat. The wow Page 7 of 12 TtiL- 0021t)0 AL+, 60A-4 -:),1-d kGo}1 k. 664 < < -t ` ttc) (L L, ,cc1Z2. (.vrc .� • • application does not contain a wildlife checklist (available from the County's GIS system, or from the DOW) or any formal analysis of possible wildlife impacts. Rob Hykys has provided the DOW WRIS Data checklist at staff s request. It indicates the following wildlife habitat lies entirely within the subject area: Black Bear Overall Range, Elk Winter Range, Elk Overall Range, Mule Deer Winter Range, Mule Deer Severe Winter Range, and Mule Deer Overall Range. The following wildlife habitat lies partially within the subject area: Bald Eagle Active Nest Site. To date, the DOW has failed to make any comment on the application. Staff has historically had a very difficult time getting responses during the hunting season. Staff suggests that the applicant amend the covenants to require vyildlife-friendly fencing specifications. (9/0g...te JZZtee4 Assessment / Fees: As determined by Section 9:80 of the Subdivision Regulations, the applicant will be required to dedicate a portion of the gross land area for open space, parks, or schools, or pay fees in lieu thereof ($200 per each newly created parcel). The property owner should be aware that the current agricultural valuation status of the property will change following subdivision. This area appears to lie in traffic study area 1 of the capital improvements plan. The applicant can expect to pay about $2,800 per single family dwelling, minus the appropriate discounts. In the event any fees increase before the time of final plat, the increased fees shall be paid. L. Utilities: The application states that Holy Cross has erected an additional power pole at 2102 CR 321 to serve the two new residences. The lot on CR320 has power located directly across the road. Public Service will provide natural gas and has extended service from CR321 to the parcel. U. S. West will provide telephone service. No cable t.v. is available. All utilities shall be buried. The application also states that access to all utilities will be the cost responsibility of individual lot owners to tie into existing utility outlets. This is not acceptable and shall be the developer's responsibility, as is customary, to extend the utilities to the lot lines of the newly created lots (in cases where the utilities are not located along CR320). M. Covenants, Plat Notes, and other issues: ,,11 L�,'vl (M �R ''`� The "Declaration of Covenants, well sharing, irrigati water use aee��' must S g .- become covenants administered by an incorporated HOA, as required by the Subdivision .0 O c Regulations and discussed 'reviously in this ,report. �� `, r, �� ko l l 1 rl LL4,v� 1 h"j�-' 1"1^ 1 6 _Q).e_ ri zSdL 10 `� usL 1 The plat shoul amende�ollows: Remove the fence lines shown; Provide legal descriptions for each of the newly created lots. 2) Plat note #14 needs to be completed to read: "All exterior lighting will be the minimum amount necessary and all exterior lighting will be directed inward, towards 41`'.;� the interior of the subdivision, except that provisions may be made to allow for safety tILP 6S�" Page 8 of 12 Iv� • . lighting that goes beyond the property boundaries." 3) The need for engineered foundations must be added to the covenants and the plat (as a plat note). 4) The covenants (paragraph 15, page 6) need to be amended to reflect the following specific language: replace "shared by a joint driveway access" with "served by a single point of access meeting the primitive residential standards called for in Section 9:00 of the Subdivision Regulations". 5) The covenants (paragraph 16, page 6) need to be amended to reflect the following specific language: "One (1) dog will be allowed for each residential unit and the dog shall be required to be confined within the owners property boundaries." 6) The covenants shall be amended to include the following restriction: "No open hearth solid -fuel fireplaces will be allowed anywhere within the subdivision. One (1) new solid -fuel burning stove as defied by C.R.S. 25-7-401, et. sew., and the regulations promulgated thereunder, will be allowed in any dwelling unit.

At your request and in accordance to Senate 13iI1 35 (1972) this office has reviewed the materials submitted and conducted a site inspection on September 20, 2000. The materials submitted included a Soils do Geology/Hazards Evaluation, Water Supply, and Wastewater Treatment reports by Colorado River Engineering, Inc. Please consider our observations and recommendations in your review of this land use application. The site is on the easternmost edge of Ta.ughenbaugh Mesa. The mesa was formed by ancient coalesced debris (lows that have created the fan or apron appearance towards the north. A mantle of windblown loess of variable thickness also covers the mesa. The subdivision lies on a relatively flat surface that has a gentle slope (5% grade) to the northeast. Two Iarge 5 -acre lots arc proposed with the remaining land included in the parcel that contains the existing home. During our site inspection we found no geologic hazards that would significantly impact.any resid itial construction cm these lots. No preliminary geotechnical investigation that includes test borings was submitted. The loess sods, if thick, may have the ability to compact when wctted. We recommend that site specific foundation irivt' tigatiuns required that includes test borings and soil testing. 1 helot suers arc ample to support ISDS for the two parcels. it was noted that the percolation rates were relatively rapid. Additional percolation tests will be required once septic field locations are determined to insure that the site specific percolation rates do not exceed the minimum for "non-enginocied" systems Provided site specific investigations and foundation designs are conducted, this office has no concerns with the development as planned.

Water Division 5, Water District 45 Bill Owens Governor Greg E. Walcher Executive Director Hal D. Simpson, P.E. State Engineer Dear Ms. Lyon: We have reviewed the above referenced proposal to subdivide approximately 51 acres into three residential Tots of 5, 5, and 41 acres. Each lot is proposed to have one single-family dwelling. The household and domestic animal water supply for the three lots is to be provided by a shared well. Irrigation water is to be supplied through the use of 0.52 cubic feet per second (cfs) of the Taugenbaugh Ditch (decreed in Civil Action Nos. 89, 934 and. 955, Garfield County District Court, and in Case No. W-2180, District Court for Water Division 5). Each of the five acre lots are to be limited to 3,000 square feet of lawn and garden irrigation with a five percent interest of the 0.52 cfs, or 0.026 cfs for each lot. The owner of the 41 -acre parcel will retain ownership of the remaining ninety percent, or 0.468 cfs, and may irrigate as much of this lot as is practicable. Well permit no. 221943 was issued on January 12, 2000, pursuant to CRS 37-92- 602(3)(b)(II)(A) which provides a rebuttable presumption that there will not be material injury to the vested water rights of others or to any other existing wells. Permit no. 221943 was issued as the only well on a tract of land of approximately 51 acres and limits the pumping rate of the well to 15 gallons per minute. The use of water from the well is limited to ordinary household purposes inside three single-family dwellings, the irrigation of not more than one acre of home gardens and lawns, and the watering of domestic animals. The permit also requires the return flow from the use of the well must be through individual waste water disposal systems of the non -evaporative type where the water is returned to the same stream system in which the well is located. The well construction report for this well was submitted on March 13, 2000, and indicates the well was constructed to a depth of 130 feet on February 4, 2000. In a two hour pump test, the well is reported to have produced 8 gallons per minute. The drawdown and recovery of the well during the pump test was not reported. With adequate storage capacity this well should provide an adequate supply for the proposed use. The use of the 0.52 cfs of the Taugenbaugh Ditch must be limited to the historic amount of acreage irrigated on the lands historically irrigated. If any increase in the acreage or change in lands irrigated is to occur, a change of water rights application must be filed with, and approved by, the water court prior to implementation of such change(s). Note that the Declaration of Covenants, Well Sharing and Irrigation Water Use Agreement (the Agreement) currently indicates that the shared well may be used for "stockwater use" and tgi Kit Lyon Leo Subdivision September 12, 2000 "stockwatering use". However, the well permit is limited to the "watering of domestic animals". The Agreement should be modified to be consistent with the well permit. Also, a typographical error in the Agreement characterizes five percent of 0.52 cfs as 0.26 cfs, rather than the correct amount of 0.026 cfs. Pursuant to Section 30-28-136(1)(h)(I), C.R.S., it is our opinion that the proposed water supply will not cause injury to decreed water rights, and is physically adequate, so long as the use of the Taugenbaugh Ditch water rights is not expanded.

The dissolved solids measured 560 milligrams per titer (mom)• This well is serving an existing home and is proposed to supply two additional residences. A water system serving three homes docs not classify as an "community water system", as defined by the Colorado Dent of Public Health & Environment, and is not subject to state regulations or review for the wager system design or water quality parameters. Additionally, the state does not have any regulatory treatment requirements for Total Dissolved Solids for cora.naunity water systems. Total dissolved solids is viewed as a secondary standard with limits established for esthetics based on characteristics that effect the desirability of the drinking water supply. This test will serve as an informative tool for the potential lot purchasers with respect to water quality data but will not effect the water system design or treatment requirements. To this end, we have requested that the testing laboratory complete further tests to define the components of the solids(i.e. hardness, lts, sulfates, etc--). We will forward the test results, as they become available. As ageneraindicatora of water quality along the Grand Valley we have researched Total Dissolved Solids records for community water systems. The health department reported the following available records: Water System Date Total Dissolved Solids (mg/1) Town of Silt 7/89 540 11/90 873 7/91 539 City of Rifle 6/90 260 7/90 530 Battlement Mesa 4/90 740 Elk Creek Subdiv. 1989 1070 The total dissolved solids in the Leo Well is similar in water quality to other water suppliers in this part of the county.

It is my understanding that each of the two five acre lots will each have its own ISDS. The ISDS systems are to be pumped out every three years to be in compliance with the propose land owners association rules. In addition all three homes will be served by one water well. The water well has been tested and found to be more than adequate to meet the needs of all three households. The waters is potable and has been thoroughly tested and is currently of no concern.

It is her concern as well as the Division of Wildlife for fencing on the property to be wildlife friendly. I provided our Habitat Partnership Programs fencing handbook to Ms. Leo and discussed fence heights and wire spacing specifications at an on site visit I made to Leo's property. She stressed at that time the concern for wildlife movement and not wanting to create any barriers. We also discussed the type of wire to be used because of potential for wire cuts on her horses. Smooth wire was her choice for both domestic animals as well as wildlife. If fences are constructed to the specifications provided)deer and elk should not have problems negotiating their way across this property.
