Applicant: Gary and Linda Nathanson, represented by Jack Palomino Location / Zoning: Lot 3 , Ute Park Subdivision. This is a . 744 acre parcel located on the south side of the east end of Ute Ave. across from the Aspen Club. The zoning is AH Affordable Housing. Request: The applicant seeks 8040 approval to construct a single family residence. Process: The Planning Commission shall make a final determination on 8040 Greenline review. Background: This parcel is one of three free market lots created in the Ute Park AH Subdivision approved in 1992 . Each of the free market lots must receive individual 8040 Greenline approval. The Nathanson review has been submitted in conjunction with one of the other free market lots in the subdivision, the Winnerman 8040 review. The deed restricted townhomes in the development have been completed and are occupied at this time. The Ute Park Subdivision is impacted by two avalanche chutes. The original subdivision review noted red zones (greater hazard) and blue zones (lesser hazard) on the created parcels. The Nathanson parcel includes a platted building envelope which identifies a portion of the envelope in the blue zone. Within the application, avalanche consultant Art Mears submitted comments on appropriate building and site design to mitigate avalanche hazards of the blue zone. A revised site plan was submitted on May 27 showing the structure to be located outside of the blue zone area. Referral Comments: Referral comments were requested from Parks, Engineering and Water Departments. Referral memos are attached as Exhibit "A" . The summaries are as follows: Engineering (Chuck Roth) : 1) Run-off from the site during construction must be prevented by detention ponds, hay bales, or similar methods. 1 111 • • 2) All activity should be prevented outside the limit of construction to protect the native vegetation - fencing should be installed at the building envelope as a minimum measure. 3) Regrading outside of the building envelope cannot take place without a variance. Driveway grading appears to be excessive, beyond the scope of the retaining wall. The retaining wall is shown as rock wall in some drawings, and concrete wall in others. 4) The grading plan within the envelope is not explicit unless "tie-back wall" construction is employed. 5) The avalanche warning signs as required by the subdivision approval have not been erected. 6) The Fire Marshall shall sign off on building permits regarding fire access and building sprinklers (required as a condition of subdivision approval) . Parks (Rebecca Baker) : 1) No detailed landscape plan has been submitted. 2) Tree removal permits are required for any tree 6"diameter or greater which will be removed or relocated. Submit for tree permits at least two weeks prior to submitting for building permit. 3) Protection of existing vegetation outside of the building envelope is critical. A barricade must be erected and inspected by Parks or Planning prior to any grading or storage on the site. 4) The deck at the northwest corner of the house should be reduced to save the aspens located there. Staff Comments: 8040 Greenline Pursuant to Section 24-7-503 of the Municipal Code, the following review criteria pertain to any development above, or within 150 ' below, the 8040 ' elevation line: I. The parcel on which the proposed development is to be located is suitable for development considering its slope, ground stability characteristics, including mine subsidence and the possibility of mud flow, rock falls and avalanche dangers. If the parcel is found to contain hazardous or toxic soils, the applicant shall stabilize and revegetate the soils, or, where necessary, cause them to be removed from the site to a location acceptable to the City. Response: The application states that the building envelope is located off of 30% slopes. The bulk of the structure is located in the "unconditional" portions of the building envelopes, out of the identified avalanche zones. Because the site plan shows the structure out of the blue zone, it does not have to follow the recommendations of hazard consultant Art Mears. Staff believes that the avalanche zones must be shown on any graphic depictions of the property, ie. building permit site plan, landscape plan, etc. 2 • • • II. The proposed development does not have a significant adverse affect on the natural watershed, runoff, drainage, soil erosion or have consequent effects on water pollution. Response: The development must comply with drainage requirements which call for an engineered drainage plan stamped by an engineer and approved by the City Engineer prior to issuance of any building permits. Hay bales, detention areas or similar methods must be used downslope of any soil disturbance (at the building envelope line) to stop loose or waterborne soils. Any regraded or disturbed areas must be revegetated and mulched immediately. III. The proposed development does not have a significant adverse affect on the air quality in the City. Response: This development will not affect air quality in significant levels. No wood burning fireplaces are allowed. IV. The design and location of any proposed development, road, or trail is compatible with the terrain on the parcel on which the proposed development is to be located. Response: This lot does not provide a trail alignment, but a pedestrian easement exists along its eastern border. Per the drawings, the private access road calls for fairly extensive cuts into the hill and retaining walls. As mentioned in the Engineering referral, the regrading above the road seems excessive. Planning staff has met with Hans Brucker, the subdivision' s design engineer, to explore methods of reducing the significant backslope cut for the private driveway. Hans understands staff ' s concerns about visual impacts and revegetation concerns. He will work on minimizing the slope cuts. This may entail raising the retaining wall somewhat. The original representation in the subdivision review stated that the retaining wall would be 4 ' -6 ' tall . Staff continues to recommend that landscaping be planted in front of the wall to reduce the visual impact of the wall . This should be done upon completion of the wall when revegetation takes place. V. Any grading will minimize, to the extent practicable, disturbance to the terrain, vegetation and natural land features. Response: As mentioned above, staff is concerned about the backslope above the private drive and its impact to the native vegetation. Concerning the regrading plan, the structure has gone through several designs which have set the building into the hillside. The extent of downhill intrusion is limited to the edge of the deck. Parks staff reflects upon the mature aspens which are to be removed because of the proposed deck at the northwest corner of the house. Because these trees are some of the more substantial ones 3 /r,, • • on the site, staff has conditioned the approval with the requirement that the deck must be reduced to keep footers and other related construction from the trees. All excavation must be done from the "inside out" from the upper part of the site. Prior to any construction activity, a sturdy, visible barricade must be erected along the building envelope lines (east, south and west) and no closer than 5 feet to the aspens at the northwest corner of the house. Planning must inspected the barricades prior to commencement of grading or material storage on the property. Revegetation on the east, south and west sides of the structure must only use native plant species such as found elsewhere on this site. Non-native species may only be used on the northern entry side of the home. VI. The placement and clustering of structures will minimize the need for roads, limit cutting and grading, maintain open space, and preserve the mountain as a scenic resource. Response: This single structure is within the platted envelope. The building is located out of the "blue" avalanche zone. The approximate 60 ' width of the building will be very visible from Ute Ave. , therefore staff is adamant about maintaining the young aspens between the building envelope and the pavement edge. It should be pointed out that the structure was redesigned after discussions with staff to fit within the narrower "unconditional" portion of the building envelope. There shall be no future grading on the site without 8040 review. The open field to the west of the residence shall remain undisturbed except for necessary control of weed pests as specified by the 1990 Colorado Weed Management Act and Pitkin County Land Management Department. VII. Building height and bulk will be minimized and the structure will be designed to blend into the open character of the mountain. Response: The floor area ratio of the four bedroom house is approximately 5 , 088 square feet. The proposed building has an approximately 60 foot wide facade. The height maximizes the allowable 25 ' limit of the AH zone district (with the ridge 5 ' higher as allowed by the land use regulations height definition) . The applicant proposes to use "modest colors and material" . Staff recommends that the stucco specified in the elevation drawings and any other paint colors be medium or darker earth tones to make the building less visible on the hillside. VIII. Sufficient water pressure and other utilities are available to service the proposed development. Response: "Will serve" letters were provided by the water and 4 • • sanitary sewer utilities during the subdivision reviews in 1992 . IX. Adequate roads are available to serve the proposed development, and said roads can be properly maintained. Response: The Ute Park Subdivision participated in the Ute Avenue Improvement District. X. Adequate ingress and egress is available to the proposed • development so as to ensure adequate access for fire protection and snow removal equipment. Response: The private driveway must be constructed in accordance with the City' s driveway requirements. At the time of subdivision review, the Fire Marshal requested that the driveway be snowmelted, but this did not become a condition of approval for the subdivision. XI. Any trail on the parcel designated on the Aspen Area Comprehensive Plan: Parks/Recreation/Open Space/Trails Plan map is dedicated for public use. Response: There were no trails dedicated on this parcel during the subdivision approval. A 10 ' pedestrian easement allows access from the upper two lots in this subdivision down to Ute Ave. Recommendation: The Planning Office recommends approval of the Nathanson 8040 Greenline review with the following conditions: 1) Run-off from the site during construction must be prevented by detention ponds, hay bales, or similar methods to be approved by the City Engineer prior to the issuance of any grading or building permits. 2) Terracing of the ground shall (including any retaining walls) not extend beyond the line of the deck. 3) Excavation shall occur from the "inside out" from the uphill side of the property. No equipment is permitted outside of the building envelope. 4) Prior to any grading or storage activity on the site, a sturdy, visible barricade shall be erected along the building envelope lines, and no closer than 5 feet to the aspens at the northwest corner of the house, to protect the existing grades and vegetation. 5) The deck outside of the master bedroom shall be reduced in 517,E ,• • !" • `7► .- • Awe _ _.u�/^ —' pl ��,." �. _ t to retain the mature aspens at the northwest corner of the house ' 03k1/#4714 ffeb`e \-) ni-;j4 -t112124 eljte". aJA;p1N -1101-'1 (.6.121t, • • • 6) Only native vegetation species as typically found on this site shall be used for revegetation of disturbed soil along the east, south and west side of the residence.

Each of the specific standards are addressed below: 1. No development is proposed for any location designated by the avalanche engineer as high avalanche hazard (see Avalanche Engineers letter of November 1, 1991). Part of the building envelope is designated as being of moderate hazard, and special structural design will be used for that part of the building in this area as prescribed by Arthur Mears letter of January 11, 1994. No hazardous or toxic soils exist on the site (see attached soils report). 2. The natural drainage of the site has been and will be protected. The building envelope has been carefully sited to avoid 30% slopes and predominant vegetation. Erosion control netting will be used during construction and revegetation of any regraded or disturbed areas will be done immediately upon completion. 3. A single-family residence is consistent with the existing use of the surrounding area. Since wood-burning fireplaces are not allowed, this development will not adversely affect the Aspen air quality. Dust suppresion measures will be taken during construction. 4. The proposed development will be set into the slope of the lot such that the height and bulk of the residence is minimized and is compatible with the existing terrain. 5. Regrading of the site will be minimized by designing the project sensitive to the site and its terrain. 6. Only one structure will be built on the site and it the building envelope is located so to minimize disturbance to the natural vegetation of the site. 7. The design will set the residence into the slope of the lot such that the height and bulk of the residence is minimized and is compatible with the open character of the mountain. From the access above, the home will appear as a one story structure and from below it will appear as two-stories. 8. The subdivision was created in consultation with the Aspen Water Department and the Aspen Consolidated Sanitation District. Both agencies have provided "will serve" letters. Further, City of Aspen Ordinance 18, Series of 1992 granted an exemption to Ute Park Subdivision with regard to the moritorium to the expansion of the municipal water system. 9. The Ute Park Subdivision has established a private access road which will serve this project and the other single-family residences of the subdivision. This road will be properly maintained by the homeowners association. 10. Ute Avenue and the private access road will provide access for emergency vehicles. A turn-around for emergency vehicles has been provided at the end of the access road. Snow removal will be the responsibility of the homeowners association. 11. No designated trails exist on this parcel. 93145 R3 3/8/94 It, 23200 STATE HIGHWAY 82 P.O. BOX 1 640 BASALT,COLORADO 61 621 13033927-3167 ARTHUR I.MEARS, P.E., INC.

Box 1640 Basalt, CO 81621 Dear Mr. Mathis: I completed a site inspection of the building sites on Lots 2 and 3, Ute Park Subdivision on January 6. Portions of both building envelopes are within range of avalanches, as you know. The western portion of both envelopes are most severely exposed; avalanche exposure and avalanche loads decrease in an easterly direction. I offer the following suggestions which should aid in the preliminary design process. • a. Design the south side of both buildings for avalanche loads. Loads have not been • determined but will probably be in the range of 150 — 400 lbs/ft2. These load magnitudes can be reduced if the exposed uphill sides of buildings deflect avalanches through small angles. Ramp roofs facing the avalanche direction are ideal and recommended. b. Ideally, windows and doors should be avoided on the uphill building surfaces facing avalanches. If doors and windows are planned on these surfaces, they must also be designed for avalanche impact. Small, reinforced glass spans can be designed for avalanche loads. Avalanches will flow through the forest in the "unconditional" zone and will probably carry small tree limbs in the flow during the extreme conditions that must be designed for. c. Eliminate structures such as decks and patios that will concentrate activities on the uphill (south—facing) sides of buildings where people will be exposed to avalanches. My loading analysis can be completed after I receive plan and elevation views of the proposed buildings. Please contact me if you have questions. Sincerely, 0. C , nteCtc�J(AAA Arthur I. Mears, P.E.

This plan is undated but I refer to the version sent to me on October 28 . The following comments refer to that • plan and to issues discussed during my site visit of October 23-. a. Building envelopes on Lots 2 and 3 are located outside the "Red, " or high hazard avalanche zones. b. Portions of the building envelopes on -Lots 2 and 3 are within the "Blue, " or moderate-hazard avalanche zone, however building within the blue zone will -require a .conditional use permit, as indicated on the plan. Structures in the blue zone will require. site- specific design for avalanche forces. c. The building envelop on Lot 1 is located within • both "Red" and "Blue" avalanche zones and is partially outside of avalanche zones. This building must be . • specially designed to stop avalanches at the uphill end, thus modifying the Red zone and preventing avalanches from reaching Lot 4 . Such design is technically feasible, but design specifications have not been developed. d. The access road to the development passes through the "Ute Trail" avalanche path. Portions of the access road will probably be reached by avalanches every 5 to 10 years, approximately. Hazard to road users will be small because traffic is light. Please contact me if you have any additional questions. i Sincerely, Arthur I . Mears, P.E.

The major impacts of both of these projects involve tree removals and landscaping. The existing landscape of Lot 1, the Nathanson property,is primarily aspen grove. A vegetative protection zone should be maintained between the building envelope and the 10 foot right of way parallel to Ute Avenue. No vegetation should be removed from this area and the contractor should be encouraged to put up snow fencing or similar type fencing to protect this area. Additionally, several significant aspens are shown on the north west corner of the property which are proposed to be relocated for the deck construction. We would recommend reducing the deck on that side in order to save those trees. A tree permit must be submitted two weeks prior to an excavation permit to insure an acceptable mitigation plan for other tree relocations and/or removals. e innerman lot,lot 2,is primarily sub alpine forest with many significant fir, aspenn andofither pines propose to be removed. The proposed plan shows 87 +caliper inches of..eo ii'ferous trees to be removed 8 cah'per inches of deciduous tree to be removed. The trees are a significant loss to the area andrrjgation will be required on a comparable worth basis either on site or dedicated monetarily to the City of Aspens trey a,,.management program. Additionally, a 21 inch fir tree close to the 8070 elevation linjs:own to be removed of which I can see no necessity for its removal. This tree should be saveddand protected during construction,including setting up any protective fencing around;.the so no digging occurs within five feet of the dripline of the tree.

Storm Runoff During Construction - The application makes,reference to providing for protection of the site during construction from damage due to erosion. A requirement that was lacking during the PUD review that should be included at this time is that protection must be provided during construction so that no runoff from soils exposed by excavation be permitted to leave the site. This is typically accomplished as suggested in the application letter by detention ponds and hay bales. 3. Vegetation & Scenic Resource - The application is incomplete in responding to review standards 5 and 6. The applicant should be required to install construction fencing to define the limits of construction activity and to protect the existing vegetation, natural land features, and scenic resource. The applicant is encouraged to preserve as much of the native vegetation as possible, but in any event, the fencing should protect at a minimum, the area outside of the approved building envelope. As with the Herron Park Place condition of approvals, it is suggested that it be stated that "the Zoning Enforcement Officer shall periodically inspect the site to determine compliance with" construction fencing, vegetation preservation, and erosion control measures. Item number 5 of the supplemental materials is unclear. Regrading of the site outside of the approved building envelope is not permitted. Fill is indicated outside of the approved building envelope. Since this is in the area between the driveway and the 1 l • • approved building envelope, it may not be unreasonable to permit the variance. 4. Extent of Cut Slopes - The information contained in the application is unclear. The drawings show the structure set into the hillside as though there were no cut slopes used to accomplish the construction. Current technology does provide techniques capable of such construction, but the application does not discuss the details. The construction process is called "tied back walls," and the walls can be constructed from the top down so that no laid back cut slope is necessary for constructing foundation walls. The limit of grading shown on sheet A5 for the driveway appears to be much greater than necessary. The grading should not need to exceed the space needed for the proposed rock retaining wall. The building permit drawings should include one or more sections through the proposed driveway. 5. Retaining Wall - The plans show a retaining wall alongside the driveway. The plans are inconsistent with the wall which appears to be a concrete wall in some drawings and a rock wall in other drawings. • 6. Avalanche Warning Signs - The signs required by item 8, Section 2 of Ordinance No. 18 (Series of 1992) have not been installed. It should be a condition of approval that the avalanche and rockfall warning signs be installed prior to the issuance of any further permits. 7. Hazardous or Toxic Soils - Item number 1 of the supplemental materials states that "no hazardous or toxic soils exist on the site (see attached soils report)." I did not find this information in the soils report. At the same time, it is not a requirement that an applicant conduct a hazardous or toxic soils survey for the property. The building permit drawings should contain a general note based on review standard number 1 stating, "If the parcel is found to contain hazardous or toxic soils, the property owner shall stabilize and revegetate the soils, or, where necessary, cause them to be removed from the site to a location acceptable to the city." 8. Please note that concerning the approvals for the entire Ute Park Subdivision, the drainage improvements have not yet been completed for Lot 4, and the escrowed funds for those improvements should be maintained until such time as those improvements have been completed.

Galena. Aspen, CO 81611 RE: Nathanson Residence Ms. Lackner: Herewith, please find the 8040 Greenline Application for the Nathanson Residence. This is in accordance with the preapplication conference Kim Johnson had with Ted Guy on December 15, 1993 and is submitted in coordination with the neighboring Winnerman Residence. Our project is for a single-family residence to be located on Lot 3, Ute Park Subdivision, Aspen, Colorado. Many of the Review Standards regarding geology, soils, drainage, air quality, utilities, roads and public space have already been addressed in the Ute Park P.U.D. approval as passed by the City of Aspen in Ordinance 18 (1992). Ordinance 18 placed the following restrictions on this lot: None, except those applicable to the subdivision, and - "Any hazardous or toxic soils must be stabilized and re-vegetated or removed to a site acceptable to the city." - "Prior to constructions, a fugitive dust control plan must be obtained from the , Colorado Pollution Control Division and this office." These restrictions will be adhered at the when building permit applications are submitted and through construction. Erosion control measures such as construction of a holding pond, pinning hay bales and erosion channels to catch sediment will be utilized. With regard to issues of the design, building height and bulk, and grading, the residence will be set into the slope of the lot such that the height and bulk of the residence is minimized and is compatible with the open character of the mountain. Color and materials will be modest and from the access above, the home will appear as a one story structure. From below it will appear as two-stories, but most of the existing vegetation will remain on this side of the home further screening the building from view. The home is located near the access road and will require a minimum of driveway length and grading. Please notify us of our scheduled hearing date and time. Enclosed is a check for $1,074.00, four copies of this submittal, and one reduced copy, as requested.

APPLICANT has submitted to CITY an application for Nathanson Residence (hereinafter, THE PROJECT). 2. APPLICANT understands and agrees that City of Aspen Ordinance No. 77 (Series of 1992) establishes a fee structure for Planning Office applications and the payment of all processing fees is a condition precedent to a determination of application completeness. 3. APPLICANT and CITY agree that because of the size, nature or scope of the proposed project, it is not possible at this time to ascertain the full extent of the costs involved in processing the application. APPLICANT and CITY further agree that it is in the interest of the parties to allow APPLICANT to make payment of an initial deposit and to thereafter permit additional costs to be billed to APPLICANT on a monthly basis. APPLICANT agrees he will be benefited by retaining greater cash liquidity and will make additional payments upon notification by the CITY when they are necessary as costs are incurred. CITY agrees it will be benefited through the greater certainty of recovering its full costs to process APPLICANT'S application. 4. CITY and APPLICANT further agree that it is impracticable for CITY staff to complete processing or present sufficient information to the Planning Commission and/or City Council to enable the Planning Commission and/or City Council to make legally required findings for project approval, unless current billings are paid in full prior to decision. 5. Therefore, APPLICANT agrees that in consideration of the CITY's waiver of its right to collect full fees prior to a determination of application completeness, APPLICANT shall pay an initial deposit in the amount of $ which is for hours of Planning Office time, and if actual recorded costs exceed the initial deposit, APPLICANT shall pay additional monthly billings to CITY to reimburse the CITY for the processing of the application mentioned above, including post approval review. Such periodic payments shall be made within 30 days of the billing date. APPLICANT further agrees that failure to pay such accrued costs shall be grounds for suspension of processing.

CONCLUSIONS The proposed multi-family housing should be founded with spread footings bearing on the natural granular soils and designed for an allowable soil bearing pressure of 3000 psf. Other design and construction criteria relating to geotechnical aspects of the proposed building are presented in the body of the report. PURPOSE AND SCOPE OF STUDY This report presents the results of a subsoil study for the proposed multi-family housing to be located across from the Aspen Club on Ute Avenue,. Aspen, Colorado. The project site is shown on Fig. 1 . The purpose of the study was to develop recommendations for the foundation design. The study was conducted in accordance with our agreement for geotechnical engineering ser- vices to Aspen Properties, dated November 22, 1989. A field exploration program consisting of exploratory borings was con- ducted to obtain information on subsurface conditions. Samples obtained during the field exploration were tested in the laboratory to determine their engineering characteristics. The results of the field exploration and labora- tory testing were analyzed to develop recommendations for foundation types, depths and allowable pressures for the proposed building foundation. The results of the field exploration and laboratory testing are presented in the report. This report has been prepared to summarize the data obtained during this study and to present our conclusions and recommendations based on the proposed " - construction and the subsoil conditions encountered. Design parameters and a = discussion of geotechnical engineering considerations related to construction rf of the proposed project are included in the report. . PROPOSED CONSTRUCTION The proposed multi-family housing will be a two-story wood frame struc- ture with a building footprint of approximately 60 feet by 80 feet. The ground floor level will be structural over a crawl space or slab-on-grade. Grading for the structure is expected to be relatively minor with cut depths • between about 4 to 8 feet. We assume relatively light foundation loadings, typical of the proposed type construction. If building loadings, location or grading plans change significantly from those described above, we should be notified to reevaluate the recommendations contained in this report. SITE CONDITIONS At the time of our field work, the site was vacant and covered with about 2 feet of snow. The topography of the building envelope is moderately sloping down to the northeast at grades of 15 to 20 percent. The slope steepens to the south of the building area. The steep slopes above the site have been characterized as having snow avalanche potential on the Pitkin County Snow Avalanche map by Colorado State University (1974) and on the Environmental and Geologic Constraints map prepared for the Colorado Geological Survey (1974). There are historic avalanche tracks located on the Hoag Subdivision to the • west of. the subject site. We are not aware of historic avalanches that have impacted the project site. The proposed building area is vegetated with small aspen trees, brush and weeds. An old overgrown cart path crosses the building area from east to west. ( , ' ®' -3- FIELD EXPLORATION The field exploration for the project was conducted on December 21 and 22, 1989. Two exploratory borings were drilled at the locations shown on Fig. 1 to evaluate the subsurface conditions. The borings were advanced with 4-inch diameter continuous flight augers powered by a truck-mounted CME-55 drill rig. The borings were logged by a representative of Chen-Northern, Inc. Samples of the subsoils were taken with a 1 3/8-inch I.D. spoon' sampler. j The sampler was driven into the subsoils at various depths with blows from a 140-pound hammer falling 30 inches. This test is similar to the standard penetration test described by ASTM Method D-1586. The penetration resistance values are an indication of the relative density or consistency of the sub- soils. ' Depths at which the samples were taken and the penetration resistance values are shown on the Logs of Exploratory Borings, Fig. 2. The samples were returned to our laboratory for review by the project engineer and testing. SUBSOIL CONDITIONS The subsoil conditions encountered at the site are shown graphically. on Fig. 2. The subsoils consist of about 2 to 4 feet of topsoil overlying mainly medium dense, silty sand and gravel containing cobbles and possible boulders. Drilling in the gravels with auger equipment was difficult due to the cobbles and boulders and drilling refusal was encountered in the deposit. Laboratory testing performed on samples obtained from the borings included natural moisture content and gradation analyses. Results of grada- tion . analyses performed on small diameter drive samples (minus 1 1/2-inch • fraction) of the natural coarse granular. soils are shown on Fig. 4. The laboratory testing is summarized in Table I. • , ^ 1 No free water was encountered in the borings at the time of drilling and the "subsoils were slightly_ moist to moist. FOUNDATION RECOMMENDATIONS Considering the '"'"'41 ^^n^;t=^ns encountered in the exploratory 7or;ngs and the nature of the proposed construction, we recommend the building be founded with spread footings bearing on the natural granular soils. The design and construction criteria presented below should be observed for a spread footing foundation system. The construction criteria should be considered when preparing project documents. 1 1 ) Footings placed on the undisturbed natural granular soils should be designed for an allowable soil bearing pressure of 3000 psf. Based on experience, we expect settlement of footings designed and constructed as discussed in this section will be about 1 inch or less. 2) All existing topsoil and g soil any p any loose or disturbed soils should be removed and the footing bearing level extended down to relatively dense natural granular soils. 3) The footings should have a minimum width of 16 inches for continuous walls and 2 feet for isolated pads. 4) Exterior footings and footings beneath unheated areas should be provided with adequate soil cover above their bearing elevation for frost protec- tion. Placement of foundations at least 42 inches below exterior grade is typically used in this area. • 5) Continuous foundation walls should be reinforced top and bottom to span an unsupported length of at least 10 feet. Foundation walls acting as 1 retaining -structures should also be designed to resist a lateral earth pressure corresponding to an equivalent fluid unit weight of 45 pcf. 1 1 r j • • 6) Sliding resistance of the footing on the bearing soil can be taken as 0.4 times the dead load weight on the foundation. 7) A representative of the soil engineer should observe all footing excava - tions prior to concrete placement to evaluate bearing conditions. FLOOR SLABS The natural on-site soils exclusive of topsoil are suitable to support lightly to moderately 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 control joints should be used to reduce damage due to shrinkage cracking. The requirements for control joints and slab reinforcement should be established by the designer based on experience and the intended slab use. A minimum 4-inch layer of free-draining gravel should be placed .beneath basement level slabs to facilitate drainage. This material should consist of minus 2-inch aggregate with less than 50% passing the No. a sieve and less than 2% passing the No. 200 sieve. All fill materials for support of floor slabs should be compacted to at least 95% of maximum standard Proctor density at a moisture content near optimum. Required fill can consist of the on-site sand and gravel devoid of lvegetation, topsoil and oversized rock. UNDERDRAIN SYSTEM Although free water was not encountered during our exploration, it has been our experience in mountainous areas that local perched groundwater. may . develop during times of. heavy precipitation. or seasonal runoff. Frozen ground during spring runoff can create a perched condition. We recommend below grade i -6- , III • . construction, such as retaining walls, crawl space and basement areas be protected from wetting and hydrostatic pressure buildup by an underdrain system. The drains should consist of drain tile placed in the bottom of the wall backfill surrounded above the invert level with free-draining granular mate- . - rial. The drain should be placed at least 1 foot below lowest adjacent finish grade and sloped at a minimum 1% to a suitable gravity outlet. Free-draining granular material used in the underdrain system should contain less than 2% passing the No. 200 sieve, less than 50% passing the No. a sieve and have a maximum size of 2 inches. The drain gravel backfill should be at least 2 feet • deep. SURFACE DRAINAGE - The following drainage precautions should be observed during construction and maintained at all times after the building has been completed: 1 ) Inundation of the foundation excavations and underslab areas should be avoided during construction. 2) Exterior' backfill should be adjusted to near optimum moisture and com- pacted to at least 95% of the maximum standard Proctor density in pavement and slab areas and to at least 90% of the maximum 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 12 inches in the first 10 feet in unpaved areas and a minimum slope of 3 inches in the first 10 feet in paved areas. It may be necessary to create a swale on the uphill. side of the building to route surface water around and away from the development. t .. i -.�- • • • 1 1 4) Roof downspouts. and drains should discharge well beyond the limits of all . backfill. 1 LIMITATIONS This report has been prepared in accordance with generally accepted soil -1 and foundation engineering practices in this area for use by the client for design purposes. The conclusions and recommendations submitted in this report j are based upon the data obtained from the exploratory borings drilled at the locations indicated on Fig. 1 and the proposed type of construction. The . nature and extent of subsurface variations across the site may not become .1 evident until excavation is performed. If during construction, fill, soil, rock or water conditions appear to be different from those described herein, this office should be advised at once so reevaluation of the recommendations may be made. We recommend on-site observation of excavations and foundation 1 bearing strata and testing of structural fill by a representative of the soil engineer. • 1 ..,u,,,„ Sincerely, \� 0 REC/s�i�iy �0 c§1-.........H.'ie,,p ''� CHEN-NORTHERN, INC.•1 :.=, -,-.. - •Q y• -,,, r, c... \ / ° 24443 '• ' ow�ti BY 1 �: < i\--,L,L,-_ o •. .• �. c� Daniel E.
