This is to serve as a response to Garfield County Building Department's request for "an engineer's assessment of the switch back section of roadway and the potential need for additional grading or drainage berms at the outside of the curve". The previous letter did not address the specifics of the drainage related to the road. The drainage in this location is not of significant concem. The storm water runoff from the vast majority of the area above this location is intercepted by a ditch approximately 130 feet - 150 feet above the switch back. The area that contributes to the ditch in question consists of a portion of the roadway and the small cut slope adjacent to the roadway for a relatively short distance above the switch back. The roadside ditch that is currently in place, though shallow, will carry the small amount of storm water runofffrom this area with minimal or no impact to the driving lanes, largely due to the grade of the road and ditch. The switch back area provides a flatter grade for a length to allow the energy of the runoff to dissipate prior to leaving the roadside ditch and discharging into the adjacent natural drainage. That being said, it is the owners responsibility to insure proper maintenance of the roadside ditches and other related drainage structures. The owner may choose to expand the roadside ditch to reduce the frequency of the maintenance. It is also encouraged, though not required, by CRE that the owner use Best Management Practices (BMP's) to minimize erosion and the transport of sediment. The erosion control BMP's can include vegetation (preferred), surface roughening, artificial and temporary surface coverage (erosion control blankets, etc.) or a combination thereof. The BMP's related to sediment transportation would likely include a combination of a series of check dams with the ditch ending in a sediment trap. Other BMP's are available and effective and may work better for the owner. A qualified person familiar with local storm water regulations should be consulted, should the owner decide to implement the use of BMP's. \\HANNAH\RedirectedFolders\effo\Desktop\Variance Letter amendment 12-0S-14.docx P.O.

If you oould sketch out the area on a map that would mark the infestations and list the species teated. I have included flyers of both Canada and Musk thistle that may help you identifu between the two species. We also offer a cost-share progam that offers a partial reimbursement to lando\f,rners for weed control costs, we'll have the program again in 2015 so keep that in mind should need sorne help with the purchase of weed control materials.

We reviewed the access to the new proposed home and roughly laid out the access road and fire truck turnaround needed for this new home. I am comfortable that the access being built will be to our fire department standards. Jeff and I have an agreement that, as early as possible, I will inspect the all-weather driving surface on the access and the turn- around.

Due to the site plan not being to scale, I will need to do a site visit during construction before C of O to ensure that we can access the ADU. I don't see this is a big problem and will be happy to make the trip when the time comes. I think that Jeff has a pretty good idea on our access needs and if any corrections are needed to be made, they should be small. Your condition of approval for a final inspection from me will be adequate for out sign-off. Please let me know if you need anything else from me for this project. Thank you, Orrin D.

Jeff Nalley also revised the plan to show a T-Type turnaround area as part of the ADU driveway' ln light of your comments I am still looking at drafting a condition of approval calling for additional information on the ADU driveway and the potential for a turnaround area requirement subject to your approval.

The study was conducted in accordance with our agreement for geotechnical engineering services to JeffNalley dated November 26,2014 The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Proposed Construction: The proposed residence will be single story with slab-on-grade floor located on the site approximately as shown on Figure 1. Cut depths are expected to range between about 2 to 4 feet. Foundation loadings for this tlpe of construction are assumed to be relatively light and typical of the proposed tlpe of construction. Ifbuilding conditions or foundation loadings are significantly different from those described above, we should be notified to re-evaluate the recommendations presented in this report. Site Conditions: The proposed building site had been rough graded relatively level and was devoid of vegetation at the time of our study. The uphill, southwest part had been cut and the downhill, northeast part had been filled each on the order of 3 to 5 feet in height. Native vegetation consists of brush and pinon trees on the hillside west of the building site' We understand that the existing 2-story residence is supported on shallow spread footings and reportedly does not show signs of differential settlement distress. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating 2 exploratory pits at the approximate locations shown on Figure 1. The logs of the pits are presented on Figure 2. Thesubsoils encountered, below about I to 2 feet of mixed soil fill material, were variable and consist of sandy silty clay with gravel, cobbles and scattered small boulders in Pit I and silty clayey sand and gravel with cobbles in pit ilrtrkct- ltli"li-{1-ill$ * (-9[,r'ri.Ir]1.1'j11"" i19"6 j1. ii6l o Srlr.r,rr[,1.rrq U7L\-{{,ii,i,lh,-.i -2- 2. Results of swell-consolidation testing performed on clay samples from pit l, presented on Figures 3 and 4, indicate low compressibility under existing moisture conditions and light loading and a low to moderate collapse potential (settlement under constant load) when wetted. The sample fromT feet depth may have been partly disturbed by the rock content of the soil resulting in the higher compressibility potential than indicated by the sample from 4 feet depth. Results of a gradation analysis performed on a sa:nple of clayey sand and gravel (rninus 3 inch fraction) obtained from the site are presented on Figure 4' No free water was observed in the pits at the time of excavation and the soils were slightlymoist to moist. f,'oundation Recommendations: Considering the subsoil conditions encountered in the exploratory pits and the nature of the proposed construction, spread footings placed on the undisturbed natural soil and designed for an allowable soil bearing pressure of 1,500 psf can be used for support of theproposed residence with a risk of differential setflement due to the variablebearing conditions. The clay soils tend to compress after wetting and there could be post-construction, differential foundation settlemffit on the order of 1 to 2 inches. We should further evaluate the settlement potential and the need for compaction of the bearing soils at the time of construction. Footings should be a minimgm width of 20 inches for continuous walls and 2 feet for columns. Loose disturbed soils and existing fill encountered at the foundation bearing level within the excavation should be removed and the footingbearing level extended down to the undisturbed natural soils. Exterior footings should be provided with adequate cover above their bearing elevations for frost protection' Placement of footings at least 36 inches below the exterior grade is tpically used in this area. Continuous foundation walls should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 14 feet. Foundation walls acting as retaining structures (if any) should be designed to resist a lateral earth pressure based on an equivalent fluid unit weight of at least 55 pcf for the on- site soil as backfill. f,'loor Slabs: The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab-on-grade construction. To reduce the effects of some differential movement, floor slabs should be separated from all bearing walls and columns with expansion joints which allow unrestrained vertical movement. Floor slab confiot joints should be used to reduce damage due to shrinkage cracking. The requirements for joint spacing and slab reinforcement should be established by the designer based on experience and the intended slab use. A minimum 4 inch layer of well graded sand and gravel, such as road base, should be placed beneath slabs for subgrade support. This material should consist of minus 2inchaggregate with less than 50% passing the No. 4 sieve and less than}%o passing the No. 200 sieve. Job No. I 14 527,4 e$tecrr -3- All fill materials for support of floor slabs should be compacted to at least 95% of ma,rimum standard Proctor density at a moisfure conte,lrt near optimum. Required fill can consist of the on-site soils devoid of vegetation, topsoil and oversized rock. Underdrain System: An underdrain is not needed for the slab-on-grade construction with floor level near to above adjacent finish exterior grade. If a betow grade area is proposed, we should be contacted. Surface Drainage: The following drainage precautions should be obseled dr:ring consffuction and maintained at all times after the residence has been completed:l) Inundation ofthe foundation excavations and underslab areas should be avoided during construction. 2) Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95Yo of themaximum standard Proctor density in pavement and slab areas and to at least 90% of themaximum standard Proctor density in landscape areas.3) The ground surface surrounding the exterior of the building should be sloped to drain away from the foundation in all directions. we recommend a minimum slope of l2 inches in the first 10 feet in unpaved areas and a minimum slope of 3 inches in the first 10 feet in pavement and walkway areas. A swale will be needed uphill to direct surface runoff around the residence. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 5) Laodscaping which requires regular heavy irrigation should be located at least 10 feet from the building. Consideration should be given to the use of xeriscape to limit potential wetting of soils below the foundation caused by irrigation. Limitations: This study has been conducted in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. lVe make no warranty either express or implied. The conclusions and recommendations submitted in this report are based upon the data obtained from the exploratorypits excavated at the locations indicated on Figure I and to the depths shown on Figure 2,theproposed type of construction, and our experience in the area. Our services do not include determining the presence, prevention or possibility of mold or other biological contaminants (MOBC) developing in the future. If the client is concerned about MOBC, then a professional in this special field ofpractice should be consulted. Our findings include interpolation and extrapolation of the zubsurface conditions identified at the exploratory pits and variations in the subsurface conditions may not become evident until excavation is performed. If conditions encountered during construction appear different from those described in this Job No.114527A e&&ecn -4- report, we should be notified at once so re-evaluation of the recommendations may be made. This report has been prepared for the exclusive use by our client for design purposes. We are not responsible for technical interpretations by others of our information. As the project evolves, we should provide continued consultation and field services during construction to review and monitor the implementation of our recommendations, and toverifr that the recommendations have been appropriately interpreted. Significant design changes may require additional analysis or modifications to the recommendations presented herein. We recommend on-site observation of excavations and foundation bearing strata and testing of structural fill by a representative of the geotechnical engineer.
