A building permit cannot be issued until the Lot Line Adjustment (Case No. LLA- 11 -01) has been recorded with the Jefferson County Clerk and Recorder. The plat document has been approved and is ready for recording. 2. A copy of a deed indicating current ownership of the property is required. 3. If parking lot lighting is proposed, a lighting plan for the site lighting needs to be included within the plan set. The lighting plan should include the following: locations of all lighting fixtures and a numerical grid of lighting levels in foot candles or as isoilluminance curves, lamp types and wattages, mounting heights of all fixtures, cut sheets showing design and finishes of all fixtures and designation as cutoff fixtures. 4. The land use summary data on page L1.0 needs to be revised to represent the consolidated parcel. Please put site data on the site plan and make all calculations based on the single lot (lot 3A) that will result from the LLA. 5. On the landscape plan, landscape data should indicate the minimum required landscape area and the total amount of landscape area provided. Please include a breakdown (numeric and percentage) of "living" and "non- living" landscape areas. 6. The access proposed to the drive aisle is too wide and needs no wider than 24' and defined by curbing. 7. The minimum width of an accessible parking space is 8 % feet with a minimum accessible aisle of 5 feet. At least one van accessible space is required on the property measuring 8' in width with an 8' wide access aisle. Handicapped spaces are required to be 20' in depth. 8. Please note the dimensions of the standard parking stalls. 9. Please consider the location of the accessible parking space in the new parking area in relation to the ramped pathway to the main building. 10. Please indicate the setbacks for the accessory structure. Please address each of these comments by revising the drawings accordingly.

Reports1R11DN46703- 126-111.doc SCOPE This report presents the results of our Geotechnical Investigation for the proposed parking lot and storage building planned on the vacant parcel south of 7490 West 4e Avenue in Wheat Ridge, Colorado (Fig. 1). The purpose of this investigation was to evaluate subsurface conditions at the site and provide geotechnical design and construction criteria for the building and pavements. The scope of this investigation was described in our Service Agreement (ON 11 -0385) dated May 24, 2011. Evaluation of the property for the possible presence of potentially hazardous materials (Environmental Site Assessment) was not included in the scope. This report is based on conditions found in our exploratory borings, results of field and laboratory tests, engineering analysis of field and laboratory data, and our experience with similar conditions. The report contains descriptions of the subsoils and ground water levels found in the exploratory borings, discussion of foundation and floor support alternatives, and recommended design and construction criteria for excavations, foundations, floor systems and surface drainage. The recommendations presented in the report are based on the construction as currently planned. Revisions to the planned construction could affect our recommendations. If the proposed construction will differ from the descriptions in this report, we should be contacted to review our recommendations and determine if revisions are needed. A brief summary of our conclusions and recommendations follows, with more detailed design criteria presented in the report. SUMMARY OF CONCLUSIONS 1. Subsoils found in our boring consisted of about 2.5 feet of sandy clay and 6.5 feet of clayey sand over silty sand. The sandy clay was moist and is considered to be low swelling. The sands are non - expansive. 2. Ground water was encountered at a depth of about 9 feet. The current ground water level should not affect construction. Ground water may fluctuate seasonally and rise in response to precipitation and landscape watering.

Footing foundations are recommended for the storage building. Floor slabs -on -grade generally perform adequately on sites with soils like those found at this site. 4. Automobile parking areas can be paved with 5 inches of asphalt pavement or an equivalent composite section. Access drives, fire lanes and equipment traffic areas should have at least 6 inches of asphalt. Alternatives are discussed in the report. 5. Surface drainage should be designed, constructed and maintained to provide rapid removal of surface water away from the building and off of pavements. Water should not be allowed to pond adjacent to the building or on pavements. SITE CONDITIONS AND PROPOSED CONSTRUCTION The parking lot and storage building site is planned on a vacant parcel located south of 7490 West 45 Avenue in Wheat Ridge, Colorado (Fig. 1 and Photo 1). The parcel includes the eastern portion of Lot 2 of Ace Hardware Subdivision and is south of West 45 Avenue between Wadsworth Boulevard and Vance Street. The site is bordered by a Jefferson County Housing building and pavements on the north, Apel- Bacher Park tennis court on the east, and retail buildings and pavements on the south and west. Clear Creek is about % -mile north. JEFFERSON COUNTY HOUSING AUTHORITY 2 - - PROPOSED PARKING LOT AND STORAGE BUILDING CTL I T PROJECT NO. DN45,703.125 S:IPROJECTS1467001 N46703 .000112512. ReportsIR11ON45703- 125.R1.doc The ground surface on the site slopes gently to the northeast with overall relief of about 5 feet. The surrounding terrain slopes gently to the north, toward Clear Creek. Ground cover consists of grasses and weeds. Utility easements are generally present along the southern, eastern and northern edges of the site. We were provided with a conceptual site plan for review. The plan indicates the majority of the site will be covered with a paved lot. The northern and eastern parts will be parking spaces and the remainder will be an access drive. A 20 -foot by 25 -foot storage building is planned at the southeast corner. A small shed will be near the southwest corner. We anticipate relatively light foundation loads for the storage building and shed. The utility easement at the southern edge will be preserved. The site will slope to the northeast toward a detention pond. The pond will be about 1 to 2 feet deep and will accommodate flow from the parking lot to the north. We anticipate the northern edge of the site will be landscaped. INVESTIGATION Subsurface conditions at the site were investigated by drilling one exploratory boring at the approximate location shown on Fig. 1. Prior to drilling, we contacted the Utility Notification Center of Colorado and local sewer and water districts to identify locations of buried utilities. The boring was advanced to a depth of 25 feet using 4- inch diameter continuous - flight auger and a truck - mounted drill rig. Samples of the subsoils were obtained at 5 -foot intervals using 2.5 -inch diameter (O.D.) modified California barrel samplers driven by blows from a 140 -pound hammer falling 30 inches. A bulk sample of the surficial soil within 5 feet of the ground surface was obtained from auger cuttings. Our representative was present during drilling to observe drilling operations, log the strata encountered, obtain samples for laboratory tests and survey the elevation of the boring relative to the temporary benchmark shown on Fig. 1 (ground surface near known contour, elevation 5391 feet). Upon completion of drilling, handslotted PVC pipe was installed in the hole to facilitate a delayed ground water measurement.

Repo0s1R11DN46703- 126- 111.doe Samples were returned to our laboratory where they were examined by our engineer and tests were assigned. Laboratory tests included dry density, moisture content, percent silt and clay -sized particles (passing No. 200 sieve), Atterberg limits, swell - consolidation, Standard Proctor (ASTM D 698) and water - soluble sulfate concentration. Summary logs of the borings are presented on Fig. 2. Laboratory test results are shown on Figs. 3 and 4 and summarized on Table I. SUBSURFACE CONDITIONS About 2.5 feet of sandy clay was found at the ground surface. The clay was medium stiff or stiff based on drilling observations. A bulk sample mostly composed on the sandy clay contained 50 percent silt and clay -sized particles and showed moderate plasticity. We consider the sandy clay to be slightly expansive. About 6.5 feet of loose, clayey sand was encountered below the clay. A clayey sand sample compressed 0.4 percent when wetted under an applied pressure of 500 psf. A clayey sand sample contained 34 percent silt and clay -sized particles and showed low plasticity. A sample had a water - soluble sulfate concentration of 0.20 percent. Silty sand was encountered below the clayey sand. A sample contained 18 percent silt and clay-sized particles and was non - plastic. We consider the sands to be non - expansive. Ground water was encountered at a depth of about 9 feet during drilling and when the hole was checked on August 8, 2011. Ground water should not affect construction. Water levels may fluctuate with seasons and rise in response to precipitation and landscape irrigation. Seismicity The soil and bedrock are not expected to respond unusually to seismic activity. According to the 2009 International Building Code (IBC) (Standard Penetration Resistance method of Section 1613.5.2), and based upon the results of our investigation, we judge the site classifies as Site Class D.

ROpoN31R11DNa703420 -R1AOO Bill relatively new, properly designed and constructed buildings would be expected with a seismic event. Wind loads typically govern dynamic structural design in this area. Geologic Hazards Colorado is a challenging location to practice geotechnical engineering. The climate is relatively dry and the near - surface soils are typically dry and comparatively stiff. These soils and related sedimentary bedrock formations tend to react to changes in moisture conditions. Some of the soils swell as they increase in moisture and are referred to as expansive soils. Other soils can settle significantly upon wetting and are identified as collapsing soils. Most of the land available for development east of the Front Range is underlain by expansive clay or claystone bedrock near the surface. The soils that exhibit collapse are more likely west of the continental divide; however, both types of soils occur throughout the state. Covering the ground with buildings and pavements, coupled with landscape irrigation and changing drainage patterns, leads to an increase in subsurface moisture conditions. As a result, some soil movement is inevitable. It is critical that all recommendations in this report are followed to increase the chance that the foundations and slabs -on -grade will perform satisfactorily. After construction, the owner must assume responsibility for maintaining the structures and pavements and use appropriate practices regarding drainage and landscaping. Our investigation indicates the sandy clay is relatively moist and likely low swelling. The sand is non - expansive. The presence of expansive soils constitutes a geologic hazard. There is risk that ground heave will damage slabs -on -grade and foundations. The foundations and slabs may settle if loose or soft fill and soils are present under the foundations and slabs. The risk of foundation and slab movements can be mitigated, but not eliminated by careful design, construction, and maintenance procedures. We believe the recommendations in this report will help control risk of foundation and slab damage; they will not eliminate that risk. The owner should understand that slabs -on -grade and, in some instances, foundations may be affected by movement of the subsoils. Property maintenance will be required to control risk. JEFFERSON COUNTY HOUSING AUTHORITY 5 PROPOSED PARKING LOT AND STORAGE BUILDING CTL I T PROJECT NO. ON46,703 426 S'.WROJECTS14670010N46703. 0001 12612. ReportSIR11DN46703426- 111.Eo0 SITE DEVELOPMENT Excavation We believe the soils encountered in our exploratory boring can generally be excavated with conventional, heavy -duty excavation equipment. We recommend the owner and the contractor become familiar with applicable local, state and federal safety regulations, including the current OSHA Excavation and Trench Safety Standards. We believe the sandy clay and clayey sand will classify as Type C soils. Type C soils need maximum slope inclinations of 1%:1 (horizontal:vertical) for temporary excavations in dry conditions. Flatter slopes will be required below ground water or where seepage is present. The contractor's "competent person" should review excavation conditions and refer to OSHA Standards when worker exposure is anticipated. A Registered Professional Engineer should design excavations greater than 20 feet deep. Fill and Backfill The on -site soils are generally suitable for reuse as new fill, provided they are substantially free of debris, organics, and other deleterious material. Soil particles larger than 3 inches in diameter should not be used for fill unless broken down. If imported fill is necessary, it should have a maximum particle size of 3 inches, less than 50 percent passing a No. 200 sieve, a liquid limit less than 30 percent and a plasticity index less than 15. Potential fill materials should be submitted to our office for approval prior to importing to the site. Prior to fill placement, debris, organic matter, and deleterious material should be substantially removed from areas to receive fill. The surface to be filled should be scarified to a depth of at least 8 inches, moisture conditioned, and compacted to the criteria below. Subsequent fill should be placed in thin (8 inches or less) loose lifts, moisture conditioned to within 2 percent of optimum moisture content, and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698).

DN46,703 -125 3:IPROJECTS1467001DN46703. 000112612. ftP ft1R11DN4 6703- 12 6•R1.d= Our experience indicates fill and backfiil can settle, even if properly compacted to the criteria provided above. Factors that influence the amount of settlement are depth of fill, soil type, degree of compaction, and time. The length of time for the compression to occur can be a few weeks to several years. The degree of compression of the recommended fill under its own weight will likely range from 1 to 2 percent of the fill depth. Any improvements placed over backfili should be designed to accommodate movement. Water and sewer lines are often constructed beneath slabs and pavements. Compaction of utility trench backfili can have a significant effect on the life and serviceability of floor slabs, exterior flatwork, and pavements. We recommend utility trench backfili (if any) be placed in thin, loose lifts, and moisture conditioned and compacted according to the specifications presented previously. The placement and compaction of backfili should be observed and tested by a representative of our firm during construction. FOUNDATIONS Our investigation indicates the soils at depths likely to influence performance of foundations and floors include low swelling sandy clay and non - expansive sand. Footing foundations are recommended for the storage building and shed. Design and construction criteria for footings are provided below. 1. Footings should be constructed on natural clay and/or sand or similar moisture conditioned, compacted fill. Soils loosed during excavation or during the forming process should be removed and replaced with moisture conditioned, compacted fill. 2. Footings should be designed for a maximum allowable soil pressure of 2,000 psf. 3. To resist lateral loads, a coefficient of friction of 0.45 can be used for concrete in contact with natural sand and clay. Equivalent fluid density for the active earth pressure condition can be taken as 45 pcf. Lateral loads can be resolved by evaluating passive resistance using an equivalent fluid density of 350 pcf for the on -site soil and backfiii that is properly compacted and will not be removed. These are ultimate values; an appropriate factor of safety should be applied. JEFFERSON COUNTY HOUSING AUTHORITY 7 PROPOSED PARKING LOT AND STORAGE BUILDING CTL I T PROJECT NO. DN45,703 -125 S:IPROJECTS196700IDN46706 .000112612. Reports1R11DN46709- 126R1.dm 4. Footings should have a minimum width of at least 16 inches. Foundations for isolated columns should have minimum dimensions of 18 inches by 18 inches. Larger sizes may be required, depending upon the loads and structural system used. 5. Foundation walls or grade beams should be well reinforced, top and bottom. We recommend reinforcement sufficient to span an unsupported distance of at least 10 feet. Reinforcement should be designed by the structural engineer considering lateral earth pressures and the effects of large openings on wall performance. S. Exterior footings must be protected from frost action. Normally, 3 feet of frost cover is assumed in this area. 7. The completed foundation excavation should be observed by a representative of our firm to verify subsurface conditions are as anticipated from our exploratory boring. Fill placed below footings and slabs should be observed and tested during placement. A representative of our firm should inspect footing forms and subgrade prior to placing concrete. 8. Excessive wetting of foundation soils during and after construction can cause softening of foundation soils and result in footing movements. Proper surface drainage around the building is critical to control wetting. FLOOR SYSTEMS Risk of distress due to soil movement is considered to be low at this site. Potential movement of about 1 inch or less is considered possible. Slabs -on -grade are suitable for the building floors, provided risk of distress is acceptable to the owner. if the owner understands and accepts the risk of slab -on -grade movement and selects a stab -on -grade floor system, we recommend the following design and construction criteria. These recommendations will not prevent movement. Rather, they tend to reduce damage if movement occurs. Slabs should not be constructed on existing fill, if encountered. 1. Slabs should be placed directly on properly moisture conditioned, compacted subgrade fill. If no fill is placed below the slab, the existing soil should be moisture conditioned and compacted as discussed in Fill and Backfill 2. The 2009 International Building Code (IBC) requires a vapor retarder be placed between the base course or subgrade soils and the concrete slab -on -grade floor. The merits of installation of a vapor retarder below JEFFERSON COUNTY HOUSING AUTHORITY 8 PROPOSED PARKING LOT AND STORAGE BUILDING CTL I T PROJECT NO.ON45,703 -126 S :WROJECTSt4670010N46703.000F12W. Reporte1R1101,146703426- Rt.doc MR floor slabs depend on the moisture sensitivity of floor coverings and the building. A properly installed vapor retarder (10 mil minimum) is more beneficial below concrete slab -on -grade floors where floor coverings, painted floor surfaces or products stored on the floor will be sensitive to moisture. The vapor retarder is most effective when concrete is placed directly on top of it, rather than placing a sand or gravel leveling course between the vapor retarder and the floor slab. The placement of concrete on the vapor retarder may increase the risk of shrinkage cracking and curling. Use of concrete with reduced shrinkage characteristics including minimized water content, maximized coarse aggregate content, and reasonably low slump will reduce the risk of shrinkage cracking and curling. Considerations and recommendations for the installation of vapor retarders below concrete slabs are outlined in Section 3.2.3 of the 2006 report of American Concrete Institute (ACI) Committee 302, "Guide for Concrete Floor and Slab Construction (ACI 302.111 -04) ". 3. Plumbing and utilities that pass through the slab should be isolated from the slab and constructed with flexible couplings. Utilities, as well as electrical and mechanical equipment should be constructed with sufficient flexibility to allow for some movement. 4. Exterior flatwork and sidewalks should be separated from the structure. These slabs should be detailed to function as independent units. Movement of these slabs should not be transmitted to the foundations of the structures. 5. The American Concrete Institute (ACI) recommends frequent control joints be provided in slabs to reduce problems associated with shrinkage cracking and curling. To reduce curling, the concrete mix should have a high aggregate content and a low slump. If desired, a shrinkage compensating admixture could be added to the concrete to reduce the risk of shrinkage cracking. We can perform a mix design or assist the design team in selecting a pre - existing mix. PAVEMENTS We anticipate pavement subgrade soils will consist of low swelling sandy clay and /or non - expansive clayey sand, or similar materials. The clayey subgrade soils possess relatively poor pavement support characteristics but the underlying sand is considered favorable material. The pavement design was based on the site soil characteristics and our experience. The pavement areas will be used for automobile parking, access drives and equipment traffic areas. We recommend the appropriate areas be paved with the following minimum pavement alternatives. JEFFERSON COUNTY HOUSING AUTHORITY 9 PROPOSED PARKING LOT AND STORAGE BUILDING CTL I T PROJECT NO.

Subgrade should be proof - rolled and unstable areas removed and replaced with stable soil. Our experience indicates problems with asphalt pavements can occur where heavy trucks turn at low speeds. in areas of concentrated loading and turning movements by heavy trucks, such as at entrances, loading and unloading areas, and trash collection areas, we recommend Portland cement concrete pavement placed directly on prepared subgrade. We recommend installing 6 or 7 -inch thick concrete pads at garbage dumpster areas, sufficient in size to support the entire trash truck. The design of a pavement system is as much a function of paving materials as supporting characteristics of the subgrade. All soils that will support pavements should be scarified, moisture conditioned, and compacted prior to paving. The quality of each construction material is reflected by the strength coefficient used in the calculations. If the pavement system is constructed of inferior material, then the life and serviceability of the pavement will be substantially reduced. Materials and placement methods should conform to the requirements of the City of Wheat Ridge. All materials planned for construction should be tested to confirm their compliance with project specifications. The structural coefficient assumed for the aggregate base course in our evaluation is an R -Value of 78. A CDOT Class 5 or Class 6 base course or recycled concrete material that meets the Class 5 or 6 designation should meet these requirements. Base course quality varies considerably and can be sensitive to change JEFFERSON COUNTY HOUSING AUTHORITY 10 PROPOSED PARKING LOT AND STORAGE BUILDING CTL I T PROJECT NO.

ReporteVHIDN46703426.111.doc ME in moisture; therefore, we recommend the material planned for base course be laboratory tested prior to importing it to the site. Control joints should separate concrete pavements into panels as recommended by ACI. No de -icing salts should be used on paving concrete for at least one year after placement. Routine maintenance, such as sealing and repair of cracks and overlays at 5 to 7 -year intervals, are necessary to achieve long -term performance of an asphalt system. We recommend application of a rejuvenating sealant such as fog seal after the first year. Deferring maintenance usually results in accelerated deterioration of pavements leading to higher future maintenance costs. Recommendations for flexible and rigid pavement construction are presented in Appendix A. CONCRETE Concrete in contact with soils can be subject to sulfate attack. We measured water - soluble sulfate concentrations of 0.03 and 0.20 percent in two samples from this site, with an average of 0.12 percent. Water - soluble sulfate concentrations between 0.1 and 0.2 percent indicate Class 1 exposure to sulfate attack, according to the American Concrete Institute (ACI) Guide to Durable Concrete (ACI 201.2R -01). ACI 201 indicates adequate sulfate resistance can be achieved by using Type II cement with a water -to- cementitious material ratio of 0.50 or less. In addition, ACI 318 indicates concrete in Class 1 exposure environments should have a minimum compressive strength of 4,000 psi. Concrete should have a total air content of 6 percent ± 1.5 percent. SUBSURFACE DRAINAGE No below -grade floors are planned in the storage building. Foundation drains are not typically installed for this type of construction. if you wish to reduce risk that surface water will affect soils supporting foundations and the floor, a drain can be installed. We can provide a detail, if requested. JEFFERSON COUNTY HOUSING AUTHORITY 11 - PROPOSED PARKING LOT AND STORAGE BUILDING - - - CTL I T PROJECT NO. DN45,703.125 S:IPROJECTS1457001DN45703 .000112512. Report5%R11DN45703. 125- R1.4oc SURFACE DRAINAGE Performance of foundations, pavements and flatwork is dependent to a large degree on subsoil moisture conditions. The risk of wetting the foundation and subgrade soils can be reduced by carefully planned, constructed and maintained surface grading. Landscape and pavement areas should slope to promote good drainage away from the buildings. Roof downspouts around the building will require repair. We recommend the following precautions be observed during construction and maintained at all times after construction is completed. 1. Wetting or drying of the open foundation and utility trench excavations should be avoided. 2. Positive drainage should be provided away from the building. We recommend a minimum slope of at least 5 percent in the first 5 to 10 feet away from the foundations in landscaped areas. Paved surfaces should be sloped to drain away from the building. A minimum slope of 2 percent is suggested; more slope is desirable. Concrete curbs and sidewalks may "dam" surface runoff adjacent to the building and disrupt proper flow. Use of "chase" drains or weep holes at low points in the curb should be considered to promote proper drainage. Area drains can be installed in areas where good surface drainage cannot be established. 3. Backfill around foundations should be moistened and compacted as described in Fill and Backfill 4. Landscaping should be carefully designed to minimize irrigation. Plants used near foundation walls should be limited to those with low moisture requirements. Irrigated grass should not be located within 5 feet, and preferably 10 feet, of the foundations. Sprinklers and/or drip lines should not discharge within 5 feet of foundations. Irrigation should be limited to the minimum amount sufficient to maintain vegetation. Application of more water will increase likelihood of slab and foundation movements and associated damage. 5. Impervious plastic membranes should not be used to cover the ground surface immediately surrounding the new construction. These membranes tend to trap moisture and prevent normal evaporation from occurring. Geotextile fabrics can be used to control weed growth and at the same time allow for evaporation. 6. Roof drains should be directed away from the building. Downspout extensions and splash blocks should be provided at all discharge points. Roof drains should not be directed below slab -on -grade floors. Where this is unavoidable, drain pipes should be thoroughly pressure JEFFERSON COUNTY HOUSING AUTHORITY 12 PROPOSED PARKING LOT AND STORAGE BUILDING - CTL I T PROJECT NO.

CONSTRUCTION OBSERVATIONS This report has been prepared for the exclusive use of Jefferson County Housing Authority for the purpose of providing geotechnical design and construction criteria for the proposed project. The information, conclusions, and recommendations presented herein are based upon consideration of many factors including, but not limited to, the type of construction proposed, the geologic setting, and the subsurface conditions encountered. The conclusions and recommendations contained in the report are not valid for use by others. Standards of practice evolve change in the area of geotechnical engineering. The recommendations provided are appropriate for about three years. If the project has not been constructed within about three years, we should be contacted to determine if we should update this report. We recommend that CTL I Thompson, Inc. provide construction observation services to allow us the opportunity to confirm soil conditions are consistent with those found during this investigation. If others perform these observations, they must accept responsibility to judge whether the recommendations in this report remain appropriate. GEOTECHNICAL RISK The concept of risk is an important aspect with any geotechnical evaluation primarily because the methods used to develop geotechnical recommendations do not comprise an exact science. We never have complete knowledge of subsurface conditions. Our analysis must be tempered with engineering judgment and experience. Therefore, the recommendations presented in any geotechnical evaluation should not be considered risk -free. We cannot provide a guarantee that the interaction between the soils and a proposed structure will be as desired or intended. Our recommendations represent our judgment of those measures that are necessary to increase the chances that the structure will perform satisfactorily. It is critical that all recommendations in this report are followed during construction.

A recycled concrete alternative which meets the Class 5 or 6 designation is also acceptable. 2. Aggregate base course should have a minimum Hveem stabilometer value of 84. Aggregate base course or recycled concrete material must be moisture stable. The change in R -value from 300 psi to 100 psi exudation pressure should be 12 points or less. 3. Aggregate base course or recycled concrete should be laid in thin lifts not to exceed 9 inches, moisture treated to within 2 percent of optimum moisture content, and compacted to at least 95 percent of maximum modified Proctor dry density (ASTM D 1557, AASHTO T 180). 4. Placement and compaction of aggregate base course or recycled concrete should be observed and tested by a representative of our firm. Placement should not commence until the underlying subgrade is properly prepared and tested. Asphalt Concrete (AC) or Hot Mix Asphalt (HMA) HMA should be composed of a mixture of aggregate, filler, hydrated lime and asphalt cement. Some mixes may require polymer modified asphalt cement, or make use of up to 20 percent reclaimed asphalt pavement (RAP). A project mix design is recommended and periodic checks on the 2. HMA should be relatively impermeable to moisture and should be designed with crushed aggregates that have a minimum of 80 percent of the aggregate retained on the No. 4 sieve with two mechanically fractured faces. 3. Gradations that approach the maximum density line (within 5 percent between the No. 4 and 50 sieves) should be avoided. A gradation with a nominal maximum size of 1 or 2 inches developed on the fine side of the maximum density line should be used. 4. Total void content, voids in the mineral aggregate (VMA) and voids filled should be considered in the selection of the optimum asphalt cement content. The optimum asphalt content should be selected at a total air void content of about 4 percent. The mixture should have a minimum VMA of 14 percent and between 65 percent and 80 percent of voids filled.

Asphalt cement should meet the requirements of the Superpave Performance Graded (PG) Binders. The minimum performing asphalt cement should be PG 64 -22 for use along the Front Range. The use of PG 58 -28 or PG 58 -22 asphalt cement has been known to cause tenderness in pavements in the Front Range area and should be avoided. 6. Hydrated lime should be added at the rate of 1 percent by dry weight of the aggregate and should be included in the amount passing the No. 200 sieve. Hydrated lime for aggregate pretreatment should conform to the requirements of ASTM C 207, Type N. Paving should only be performed when subgrade temperatures are above 40`F and air temperature is at least 40`F and rising. 8. HMA should not be placed at a temperature lower than 245`F for mixes containing PG 64 -22 asphalt, and 290`F for mixes containing polymer modified asphalt. The breakdown compaction should be completed before the mixture temperature drops 20`F. 9. The maximum compacted lift should be 3.0 inches and joints should be staggered. No joints should be placed within wheel paths. 10. HMA should be compacted to between 92 and 96 percent of Maximum Theoretical Density. The surface shall be sealed with a finish roller before the mix cools to 185`F. 11. Placement and compaction of HMA should be observed and tested by a representative of our firm. Placement should not commence until the subgrade is properly prepared, tested and proof - rolled. Proof - rolling should be performed with the heaviest machine available at the time. The proof roller should be selected from machines providing both mass and high contact pressure. Portland Cement Concrete (PCC) 1. Portland cement concrete should meet CDOT Class P concrete and have a minimum compressive strength of 4,200 psi at 28 days and a minimum modulus of rupture (flexural strength) of 650 psi. A_mob mix design is 2. Portland cement should be Type II `low alkali" and should conform to ASTM C 150. Portland cement should conform to ASTM C 150. 3. Portland cement concrete should not be placed when the subgrade or air temperature is below 40 ° F. 4. Free water should not be finished into the concrete surface. Atomizing nozzle pressure sprayers for applying finishing compounds are recommended whenever the concrete surface becomes difficult to finish.

Curing of the portland cement concrete should be accomplished by the use of a curing compound. The curing compound should be applied in accordance with manufacturer recommendations. 6. Curing procedures should be implemented, as necessary, to protect the pavement against moisture loss, rapid temperature change, freezing, and mechanical injury. 7. Construction joints, including longitudinal joints and transverse joints, should be formed during construction or sawed after the concrete has begun to set, but prior to uncontrolled cracking. 8. All joints should be properly sealed using a rod back -up and approved epoxy sealant. 9. Traffic should not be allowed on the pavement until it has properly cured and achieved at least 80 percent of the design strength, with saw joints already cut. 10.

A site- specific mix design is recommended and periodic checks during the project should be made to verify compliance with specifications. We recommend the proposed pavement be constructed in the following manner: 1. The subgrade should be stripped of organic matter, scarified, moisture conditioned and compacted. Clay subgrade soils should be moisture conditioned to between 0 and 3 percent above optimum moisture content and compacted to at least 95 percent of maximum standard Proctor dry density (ASTM D 698, AASHTO T 99). Sand soils should be moisture conditioned to within 2 percent of optimum and compacted to similar minimum density. 2. Utility trenches and all subsequently placed fill should be moisture conditioned, compacted, and tested prior to paving. As a minimum, fill should be compacted to 95 percent of maximum standard Proctor dry density. 3. After final subgrade elevation has been reached and the subgrade compacted, the resulting subgrade should be checked for uniformity and all soft or yielding materials should be replaced prior to paving. Concrete should not be placed on soft, spongy, frozen, or otherwise unsuitable subgrade. 4. If areas of soft or wet subgrade are encountered, the material should be sub - excavated and replaced with properly compacted structural backfill. Where extensively soft, yielding subgrade is encountered, we recommend the excavation be inspected by a representative of our office. 5. Aggregate base course should be laid in thin, loose lifts, moisture treated to within 2 percent of optimum moisture content, and compacted to at least 95 percent of modified Proctor maximum dry density (ASTM D 1557, AASHTO T 180). 6. Asphaltic concrete should be hot plant -mixed material compacted to between 92 and 96 percent of maximum Theoretical density. The temperature at laydown time should be at least 245 °F. The surface shall be sealed with a finish roller prior to the mix cooling to 185 °F. 7. The maximum compacted lift should be 3.0 inches and joints should be staggered. No joints should be within wheel paths. 8. Paving should only be performed when subgrade temperatures are above 40 °F and air temperature is at least 40 °F and rising. 9. Subgrade preparation and placement and compaction of all pavement material should be observed and tested. Compaction criteria should be met prior to the placement of the next paving lift. The additional requirements of the City of Wheat Ridge should apply. JEFFERSON COUNTY HOUSING AUTHORITY A-4 ........PROPOSED PARKING LOT AND STORAGE BUILDING CTL I T PROJECT NO.

ReportsIR11DN46703- 1264 1.doc RIGID PAVEMENT CONSTRUCTION RECOMMENDATIONS Rigid pavement sections are not as sensitive to subgrade support characteristics as flexible pavement. Due to the strength of the concrete, wheel loads from traffic are distributed over a large area and the resulting subgrade stresses are relatively low. The critical factors affecting the performance of a rigid pavement are the strength and quality of the concrete, and the uniformity of the subgrade. We recommend subgrade preparation and construction of the rigid pavement section be completed in accordance with the following recommendations: The subgrade should be stripped of organic matter, scarified, moisture conditioned and compacted. Clay soils should be moisture conditioned to between 0 and 3 percent above optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASHTO T 99). Sand soils should be moisture conditioned to within 2 percent of optimum and compacted to similar minimum density. 2. After final subgrade elevation has been reached and the subgrade compacted, the resulting subgrade should be checked for uniformity and all soft or yielding materials should be replaced prior to paving. Concrete should not be placed on soft, spongy, frozen, or otherwise unsuitable subgrade. 3. The subgrade should be kept moist prior to paving. 4. Curing procedures should protect the concrete against moisture loss, rapid temperature change, freezing, and mechanical injury for at least 3 days after placement. Traffic should not be allowed on the pavement for at least one week. 5. Curing of the portland cement concrete should be accomplished by use of a curing compound in accordance with manufacturer recommendations. S. Construction joints, including longitudinal joints and transverse joints, should be formed during construction or should be sawed shortly after the concrete has begun to set, but prior to uncontrolled cracking. All joints should be sealed. 7.. Construction control and inspection should be performed during the subgrade preparation and paving procedures. Concrete should be carefully monitored for quality control. The additional requirements of the City of Wheat Ridge should apply. The design sections are based upon 10 -year and 20 -year periods. Experience in the Denver area indicates virtually no maintenance or overlays are necessary for a 20- year design period. We believe some maintenance and sealing of concrete joints will help pavement performance by helping to keep surface moisture from wetting and softening or heaving subgrade. To avoid problems associated with scaling and to continue the strength gain, we recommend deicing salts not be used for the first year after placement.

Tire loads from traffic are necessary to "work" or knead the asphalt concrete to keep it flexible and rejuvenated. Preventive maintenance treatments will typically preserve the original or existing pavement by providing a protective seal or rejuvenating the asphalt binder to extend pavement life. Annual Preventive Maintenance • Visual pavement evaluations should be performed each year. • Reports documenting the progress of distress should be kept current to provide information on effective times to apply preventive maintenance treatments. • Crack sealing should be performed annually as new cracks appear. 3 to 5 -Year Preventive Maintenance • The owner should budget for a preventive treatment (e.g. chip seal, fog seal, slurry seal) at approximate intervals of 3 to 5 years to reduce oxidative embrittlement problems. 5 to t 0 -Year Corrective Maintenance • Corrective maintenance (e.g. full -depth patching, milling and overlay) may be necessary, as dictated by the pavement condition, to correct rutting, cracking and structurally failed areas.

The work that we identified to be done in these areas is in varying states of deterioration. All of the work was identified that we felt was prudent to be done in the near future. You may, as you see necessary, sequence this work to accommodate your needs. We can be available to help you with determining this sequencing if requested. There is one section of the elevated slab, on the west side of Unit 9265 W. 4901 Ave, that has failed and is in need of your immediate attention. The slab has cracks full depth of the elevated slab with widths of '/2 inch and greater. The cracks are continuous for the full length of the walk. This condition is not suitable for continued use. It is also a concern for pedestrian traffic below. We recommend that this section be cordoned off immediately and not returned to use until the slab has been removed and replaced.

The case was presented by Travis Crane. He advised the Boazd there was jurisdiction to hear the case. He entered all pertinent documents into the record Board of Adjustrnent - 1 ' 07/22/04 and reviewed the staff report and digitai presentation. Staff recommended approval of the variance for reasons outlined in the staff report. Waiving the requ'uement for a 6-foot view-obscuring fence would allow views into the adjacent Apel Bacher Pazk as well as allow pedestrian access into the park from the applicant's pazking lot. The applicant has offered to allow use of their parking lot to park visitors during non-business hours and would also allow the nearby church to use the loi for overtlow pazking on Sundays. In response to a question from Boazd Member BLAIR conceming access to the pazk, Mr. Crane stated that low growing shrubs planned for the six-foot landscape buffer would allow spaces for pedestrian access through the buffer into the pazk. Boazd Member ABBOTT suggested that a formal sidewalk be installed for pedeshian access. Boazd Member BELL commented that the open landscape buffer would pxovide greater safety in terms of views into the pazk for law enforcement purposes. Boazd Member HOVLAND commended the applicant for offering parking for pazk visitors and did not believe the Board should impose a condition requiring construction of a sidewalk. Alan Feinstein DRAFT 7770 West ilOm Avenue, Westminster Mr. Feinstein, D'uector of Jefferson County Housing AuthoriTy, was swom in by Chair BLAIIL He stated that, in addition to allowing use of the pazking lot by pazk visitors and church attendees, the building's meeting room will be available for use by community groups. In response to a question from Boazd Member HOWARD, Mr. Feinstein stated the building would house fifteen employees. In response to a question from Boazd Member DRDA, Mr. Feinstein stated that landscaping plans call for low-growing shrubs with enough space in between for pedestrian access. Boazd Member ABBOTT discussed placing a condition of approval to guazazitee that the applicant would always allow access to the pazk from the pazking lot. Board Member BELL staYed that the benefit of having no fence faz outweighs any other matiers in this case and she did not believe such a condition should be placed on the applicant. Boazd of Adjustment ' Z - 07/22/04 Boazd Member DRDA stated that he would favor Boazd Member ABBOTT's suggestion for a condition in order to provide perpetuity as long as the Jefferson County Housing Authority is in this location. Board Member HOVLAND commented that the issue at hand does not invoive access to the park, but only whether or not the fence requirement should be waived. Chair BLAIR asked if there were any present who wished to address this matter. There was no response. Upon a motion by Board Member BELL and second by Board Member HOVLAND the following resolurion was stated: WLereas, the applicant was denied permission by an administrative officer; and Whereas, Board of Adjustment Application Case No. WA-04-05 is an appeal to this Board from the decision of an administrative officer; and Whereas, the property has been posted the fifteen days required by law, and in recognition lhat there were no protests registered against it; and WLereas, the relief applied for may be granted without detriment to the public wel#are and without substantially impairing the intent and purpose of the regulations goveming the city of Wheat Ridge.

Granting of the request will not be injurious to other properties in the area. 4.

He stated that this is the only house in the neighborhood without a garage and that all of his neighbors have expressed their approval of his plans. Board Member BELL commented that the proposed garage would be in chazacter with other homes in the area and wouid, in fact, be an improvement since the gazage is planned to be set back a way from the corner. Boazd Member BLAI2 commented that the garage would be an improvement over the 6-foot fences placed very close to the street in the area. Chair BLAIR asked if there were any present who wished to address this matter. There was no response. Board Member DRDA commented that there aze other locarions on the property to build a garage without the need for variance. He stated that he could not find a hardship in this case.

By supplying this information, the Wheat Ridge Sanitation District is not liable for the misidentification or misrepresentation of the subject lot. The location of the subject lot is based solely on the description provided by the requestor, and the Wheat Ridge Sanitation District is not responsibie for the way in which this information is used or disseminated. 7he subject lot at the address referenced above is entirely within the boundary and service area of the Wheat Ridge Sanitation District. Treatment of sewage generated within the Wheat Ridge Sanitation District is provided by the Metro Wastewater Reclamation District (Metro). Wheat Flidge Sanitation District facilities in this area consist of an 8 inch sanitary sewer main within Wadsworth Boulevard located west of the subject property. There is aiso an 8 inch sanitary sewer main within 45`h Avenue which runs eastward to Vance Street. It appears, however, that this dead-end sewer main terminates at a manhole east of the subject property. It is likely that either sewer main will have to be extended to properly serve this property. This parcel is subject to the assessment of both Wheat Ridge Sanitation District and Metro tap charges. The subdividers and/or developers may be required to extend sewer lines to their project sites and/or share in the cost of providing additional capacity to serve their projects. In addition, you should be aware that the District requires approvai of plans for sewer main construction, sewer service connections, determination and payment of tap fees, as well as inspection of construction by the DistricYs Engineer.

We understand plans for the building have changed from those we considered during preparation of the report. Originally, the building was planned to have a basement-level parking garage. The new building configuration has a first floor at grade and no parking level. Our investigation found soils we judge to be low swelling or non-expansive at depths likely to influence performance of foundations and floors. The new building configuration implies the upper clayey sand will directly underlie foundations and floors. The sand is considered to have relatively low risk for poor performance of floor slabs. Many variables come into play regarding perFormance of floor slabs in this area. We predicted heave of about one inch or less for this site, considering a basement floor. Similar behavior is predicted for an at-grade floor slab. We provided recommendations in our report for detailing partitions and mechanical equipment. The applicable foundation and floor slab design criteria presented in our October, 2003 report can be followed. We appreciate the opportunity to be of service.

The purpose of this investigation was to evaluate subsurface conditions at the site and provide geotechnical design and construction criteria for the project. The scope of the investigation was described in our proposal (03-0765) dated September 19, 2003. This report includes descriptions of subsurface conditions found in exploratory borings, our evaluation of engineering characteristics of the subsoils, and our opinions and recommendations regarding design criteria for foundations, floor systems, lateral earth loads, exterior f latwork, pavements and other design and construction details influenced by the subsoils. The report was prepared from data developed during field and laboratory investigations, engineering analysis of field and laboratory data, and our experience with similar projects. The recommendations contained in this report were developed based on our understanding of the development as currently planned. Revisions of the planned development could affect our recommendations. If the construction will differ from the descriptions contained in this report, we should be contacted to review the changes and provide revised recommendations and/or design criteria, if necessary. SUMMARY OF FINDINGS AND CONCLUSIONS 1. Subsurface conditions encountered in ourborings consisted of clayey sand with scattered gravel and sandy clay underlain by weathered and comparatively unweathered claystone bedrock. Samples of the clayey sand exhibited slight compression and are judged to be non- expansive. Samples of sandy clay and claystone bedrock exhibited low swell. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNN HOUSING AUTHORITY OFFICE BUILDING CTLj TJOB N0.37,662 ~ ~ 2. Ground waterwas encountered during drilling between depths of 17.5 (TH-1) and 18 feet (TH-2) during drilling. When the holes were checked several days after drilling, ground water was measured in our boring TH-1 at 11 feet (EL 5382.3). The other borings had caved at depths ranging from 7.5 feet (EL 5381.7) and 9.5 feet (EL 5378) feet. The depth at which the borings cave generally indicates depth to ground water. We recommend excavations at least 3 feet and preferably 5 feet above measured ground water levels. 3. Site soils are low swelling or non-expansive. We recommend a footing foundation for the building. Soft soils may be encountered in the excavation. Stabilization of soft soils may be required. Design and construction criteria for the foundation are presented in the report. 4. We understand the basement level of the building will be a parking garage. Site soils are low swelling or non-expansive. Slab-on-grade floors are typically used for such projects with similar site conditions. We estimate potential slab-on-grade movement due to heave is on the order of less than 1 inch. 5. Pavement alternatives include 5.5 inches of asphalt in automobile (only) parking areas and 7 inches of asphalt in fire and truck lanes. Other alternatives are discussed in the report. 6. Surface drainage should be maintained at all times to reduce risk of wetting of foundation and subgrade soils. Water should not be allowed to pond adjacent to buildings or on pavements. SITE CONDITIONS The Jefferson County Housing Authority Office Building (the site) is to be located east of the intersection of Wadsworth Boulevard and 45" Avenue. The site is located in a developed area of Wheat Ridge. The site is bordered by 45`" Avenue to the north and an alleyway with Ace Hardware beyond to the west. Apel-Bacher Park is to the east and Pep Boys automotive store is to the south. The site is currently a vacant lot, covered with weeds and gresses. The site slopes gently to the north. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDING CTL I 7 JOB NO. 37,662 ~ PROPOSED CONSTRUCTION Jefferson County Housing Authority Office Building is planned to have one story above grade, with a footprint of about 8,150 square feet, and will include one story of below-grade parking. Based on our conversations with the architect, the basement grade parking is planned at an elevation of 5384. Access to the parking level will be provided from the north. A paved parking area will be provided to the east of the building. INVESTIGATION Subsurface conditions at the site were investigated by drilling three borings at the approximate locations shown on Fig. 1. Two borings were drilled in the proposed building area to depths of 25 and 35 feet and one shallow boring was drilled to a depth of 10 feet to sample pavement subgrade. The borings were drilled using a truck-mounted drill rig and 4-inch diameter, continuous-flight auger. Samples were obtained using 2.5-inch O.D. modified California sampler. A representative from our firm was on-site during drilling to log the soils and bedrock found in the borings and obtain samples. Summary logs of the soils and bedrock found in our borings and results of field penetration resistance tests are presented on Fig. 2. The samples were returned to our laboratory for verification of field classification and testing. Laboratory testing included natural moisture content and dry density, swell-consolidation, percent silt and clay-sized particles, Atterberg limits, resistivity, pH, and watersoluble sulfates tests. Results of laboratory testing are presented on Figs. 3 through 6 and summarized in Table 1. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDING CTL I T JOB NO. 37,662 3 ~ SUBSURFACE CONDITIONS Subsurface conditions encountered in our borings consisted of clayey sand with scattered occasional gravel and sandy clay underlain by weathered and comparatively unweathered claystone bedrock. The properties of the soils and bedrock and ground water conditions are discussed in the following sections. Sand and Clav Clayey sands were encountered from the ground surface to depths of 8 to 11 feet and were occasionally interlayered with the sandy clay. A gravel layer about 2.5 feet thick was encountered in our boring TH-2 at 18 feet. The sand was loose to medium dense based on field penetration resistence tests. Samples of sand had 24 and 42 percent fines (passing the No. 200 sieve). Sandy clay was encountered beneath the sands. Field penetration resistance tests indicated the clay was soft to very stiff. A sample of sandy clay exhibited low swell (0.2 percent), after wetting under an applied pressure of 1,000 psf. A sample of sandy clay had an unconfined compressive strength of 3200 psf. Bedrock Claystone bedrock was encountered in our boring TH-1 at a depth of 28 feet. The claystone was weathered to medium hard based on field penetration resistance tests. A sample of claystone bedrock exhibited low swell (0.6 percent) after wetting under an applied pressure of 1,000 psf. Ground Water Ground water was encountered during drilling between depths of 17.5 (TH-1) and 18 feet (TH-2). When we returned to the site several days after drilling, ground HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDING 4 CTL I TJOB N0.37,662 ~ water was measured in our boring TH-1 at 11 feet (EL 5382.3). Our boring TH-2 caved at 9.5 feet (EL 5378) and boring S-1 caved at 7.5 feet (EL 5381.7). The depth at which the borings cave generelly indicates the depth of ground water. Therefore, ground water elevations at the site are assumed to range in elevation from 5378 to 5382.3. Based on our conversations with the architect the planned elevation for the below grade parking is 5384. We recommend excavations at least 3 feet and preferably 5 feet above measured ground water levels. Planned elevations for the parking structure allow for less than 2 feet of separation between the structure and ground water. We recommend raising the parking structure elevation to 5385.5 or greater. SeismicitV Based upon the 1997 Uniform Building Code (1997 UBC) the site is located in Seismic Zone 1. Subsurface conditions indicate Soil Profile Type Sp. If the 2000 International Building Code (2000 IBC) applies, the site is Site Class D. The subsoil and ground water conditions indicate low susceptibility to liquefaction. SITE DEVELOPMENT Fill may be required to achieve final site grades. Excavation to depths of about 10 feet are anticipated for the below grade parking. Excavation We believe the soils penetrated by our exploratory borings can be excavated with conventional, heavy-duty excavation equipment. Bedrock was encountered in our borings but will not likely be encountered in the excavation. We recommend the owner and the contractor become familiar with applicable local, state, and federal safety regulations, including the current OSHA Excavation and Trench Safety Standards. Clay soil will likely classify as Type B and the sand will likely classify as HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDING 5 CTL I T JOB N0.37,662 ~ Type C. Assuming dry conditions, Type B soils require maximum slope inclination of 1:1 (horizontal:vertical) and Type C soils require a maximum slope of 1.5:1, for temporary excavations. Moist to wet soils were encountered in our borings. Slopes inclinations may have to be shallower. The contractor's "competent person" should observe soils exposed in excavations and referto OSHA regulations when personnel exposure is anticipated. Water and sewer lines are often constructed beneath pavement areas. Compaction of trench backfill can have a significant effect on the life and serviceability of pavements. We recommend trench backfill be moisture conditioned and compacted as specified below. Placement and compaction of fill and backfill should be observed and tested by a representative of our firm during construction. Fill and Backfill Organic topsoil, trees, large roots and debris (if any) should be stripped before site grading and disposed of properly. On-site soils, if substantially free of debris or deleterious materials, are suitable for re-use as fill. If imported fill material is required, we recommend importing clay or sand soils with properties similar to or better than the on-site materials. A sample of the proposed fill should be submitted to our office for approval prior to importing to the site. A representative of our firm should be on-site to observe placement and test compaction of fill during construction. Areas to receive fill should be scarified, moisture conditioned to between optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698). Clay fill should be moisture conditioned to optimum to 3 percent above optimum and sand fill should be moisture conditioned to within two percent of optimum. The properties of the fill will affect the performance of slabs-on-grade and pavements. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDING CTL I T JOB NO. 37,662 6 ~ Foundation wall backfill should be placed and compacted to the criteria above. However, even properly compacted fill will settle about 1 to 2 percent of the height of the fill. For the twelve-foot high foundation walis anticipated, this equates to settlement of 1-1/2 to 3 inches. Several methods may be considered to reduce the magnitude offill settlement, including backfilling with compacted clean granularfill, or cement stabilized material such as flowable fill. A clean, granular material (less than 5 percent passing the No. 200 sieve) will settle quicker than on-site material. We estimate total settlement of about 1 to 1-1/2 inches could occur with clean granular fill. Clean, granular fill should be placed and compacted to at least 70 percent of maximum relative density (ASTM D 4253 and 4254). The upper 2 to 3 feet of backfill should be clay material to limit infiltration of surface water into the granular backfill. If wall backfill settlement must be minimized, the use of flowable fill can be considered. Flowable fill is lean concrete mixture with moderate strength after hydration. The risk of settlement would be expected to be very low. Flowable fill has a relatively high equivalent fluid density (on the order of 140 to 150 pcfl before hydration, which may require additional temporary bracing of the foundation wall. Future maintenance of utilities encased in flowable fill should be considered, as flowable fill may require special excavation techniques to remove. A combination of wall backfill materials can also be considered, installing materials with lower risk of settlement beneath utility lines and exterior slabs. BUILDING FOUNDATION Our investigation indicates soils within depths expected to influence foundations consist of low swelling clays or non-expansive sands. Design and construction criteria are provided below. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNN HOl1SING AUTHORITY OFFICE BUILDING C7L I T JOB NO. 37,662 7 ~ If soft or loose soils are encountered in the excavation, crushed rock or recycled concrete with a size range of 1 to 5 inches should be crowded into the subgrade until a firm surface is achieved. 2. Footings should be designed for a maximum allowable soil pressure of 3,000 psf. 3. Footings should have a minimum width of at least 18 inches. Foundations for isolated columns should have minimum dimensions of 20 inches by 20 inches. Larger sizes may be required, depending upon the loads and structural system used. 4. Foundation walls should be well-reinforced, top and bottom. We recommend reinforcement sufficientto span an unsupported distance of at least 10 feet. 5. Exterior footings must be protected from frost action. Normally, 3 feet of frost cover is assumed in this area. 6. The completed foundation excavation should be observed by our representative to verify subsurface conditions are as anticipated from our borings. Our representative should observe footings prior to placing concrete. FLOOR SYSTEMS The lower level is planned as a parking garage. Our borings indicated the materials near the proposed parking garage floor include low swelling clay and non- expansive sands. Expansive soils are stable at their natural moisture contents, but upon wetting will heave slab-on-grade floors. The swelling pressure cannot be resisted by concentrating slab loads. Heave will likely deform and crack floor slabs and can crack interior partitions. Based on calculations using the available data and our experience, we believe heave on the order of about 1 inch or less is likely if slabs are constructed on the natural soils at this site. Risk of movement and damage due to swell must be accepted by the owner if a slab-on-grade floor is chosen. We recommend the ownerconsider recessed entries atentrances to minimize problems associated with settlement of slabs supported by backfill. Exterior slabs HUMPHRIES POLI ARCHITECTS JEFFERSON COUNN HOUSING AUTHORI7Y OFFICE BUILDING CTL I TJOB N0.37,662 ~ over foundation backfill could also be structurally supported to prevent movement if the backfill settles. Alternatively, backfill materials with lower settlement risk, as discussed in the section titled Fill and Backfill could be used below entries. Where slabs-on-grades are selected, we recommend floor slabs should be isolated from foundation components and slab penetrations to allow independent movement. Interior partition walls should be provided with at least 3-inches of vertical freedom. We recommend supporting masonry partition walls and elevator and stairway cores on footings. Frequent control joints should be provided. Mechanical equipment on the slab should consider the potential for movement. Flexibility in connections should be provided to accommodate the potential movement. If utility trenches will be routed under the floor slabs, we recommend the trenches by sloped to the perimeter foundation drain, or be backfilled with flowable cementitious fill. BELOW-GRADE CONSTRUCTION Foundation walls which retain earth will be subject to lateral earth loads which are dependent on the height of wall, backfill configuration and backfill type. We recommend design of below-grade walls using an equivalent fluid density of at least 50 pcf. This pressure assumes wall deflection of about'/z percent of its height. If less deflection is desired, we recommend designing the wall using higher equivalent fluid density, on the order of 65 to 70 pcf. If flowable fill will be used as backfill, the lateral loads on the wall will be relatively high until the fill hydrates, as discussed in the Fill and Backfill section. The coefficient of friction for sliding can be taken as 0.40 in design for lateral stability. Passive earth pressure can be calculated using 250 pcf equivalentfluid density for well-compacted soil thatwill not be removed. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDING CTL I T JOB NO. 37,662 9 ~ We recommend foundation drain be installed to reduce the risk of water infiltration into the garage and wetting of the expansive subsoils below the building. The provision of a drain will not eliminate slab movement. The drain should consist of a 4-inch diameter open joint or slotted pipe encased in free draining gravel. The drain should lead to a positive gravity outlet, such as a detention pond, or to a sump where water can be removed by pumping. Typical foundation wall drain details are presented on Figs. 7and 8. CORROSIVITY Metals that come into contact with subsoils can be subject to corrosion. To evaluate the potential for corrosion we performed laboratory tests including pH, resistivity, and water-soluble sulfate concentration from a clayey sand sample collected from our boring S-1. An acidity (pH) of 7.89 was measured, indicating a sightly basic soiis. Laboratory resistivity of 4200 ohm/cm (dry) and 1200 ohm/cm (wet) was measured. A water-soluble sulfate concentration of 0.040 percent was also measured. We believe the water-solubie sulfate concentration is negligible in the soils at this site. A qualified corrosion engineer should review this data to design protection for buried metal. CONCRETE Concrete that comes into contact with soils can be subject to sulfate attack. We measured water-soluble sulfate concentration of 0.040 percent in one sample of clayey sand from this site. Sulfate concentrations less than 0.1 percent indicate Class 0 exposure to sulfate attack for concrete that comes into contact with the subsoils, according to the American Concrete Institute (ACI). Forthis level of sulfate concentration, ACI indicates Type I or Type II can be used for concrete that comes into contact with the subsoils. In our experience, superficial damage may occur to the exposed surfaces of highly permeable concrete, even though sulfate levels are HUMPHRIES POLI ARCHITECTS JEFFERSON COUN7Y HOUSING AUTHORITY OFFICE BUILDING CTL I T JOB N0.37,662 10 ~ relatively low. To control this risk and to resist freeze-thaw deterioration, the water- to-cementitious material ratio should not exceed 0.50 for concrete in contact with soils that are likely to stay moist due to surFace drainage or high water tables. Concrete should be air entrained. PAVEMENTS One boring (S-1) was drilled in the proposed pavement area. Subgrade soils in pavement areas consisted of ciayey sand and sandy clays. Laboratory testing indicates the subgrade soils classify as A-4 with a Group Index of 1 using the AASHTO system. We determined a maximum dry density of 118.0 pcf and an optimum moisture content of 13.0 percent, using Standard Proctor (ASTM D 698) Method A criteria with a bulk sampie collected from boring S-1. We estimated a CBR value of 2. We used an Estimated Daily Load Application (EDLA) of 2 for automobile parking (only) areas and 10 for fire lanes and truck traffic areas. The following pavement alternatives were evaluated and are appropriate for use on this site (Table I).

If imported fill is used, it should have equal or better pavement support characteristics than the soils tested or the pavement sections may require HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDIN6 CTL I T JOB NO. 37,862 ~ ~ _WF revision. Imported soils to support pavements should betested and approved byour firm before use on the site. Our experience indicates problems with asphalt pavements can occur where heavy trucks drive into loading and unloading zones and turn at low speeds. In areas of concentrated loading and turning movements by heavy trucks, such as at entrances and trash collection areas, we recommend portland cement concrete pavement placed directly on prepared subgrade. We recommend a 7-inch or thicker portland cement concrete pad be constructed at dumpster locations, or other areas where trucks will stop or turn. The concrete pads should be of sufficient size to accommodate truck turning, trash pickup and delivery areas. A primary cause of early pavement deterioration is water infiltration into the pavement system. The addition of moisture usually results in softening of base course and subgrade and the eventual failure of the pavement. We recommend drainage be designed for rapid removal of surface runoff. Curb and gutter should be backfilled and the backfill compacted to reduce ponding adjacent to pavements. Final grading of the subgrade should be carefully controlled so that design cross- slope is maintained and low spots in the subgrade which could trap water are eliminated. Seals should be provided between curb and pavement and at joints to reduce moisture infiltration. Irrigated landscaped areas and detention ponds in pavements should be avoided. Additional guidelines for flexible and rigid pavement subgrade construction are presented in Appendix A. Routine maintenance, such as sealing and repair of cracks annually and overlays at 5 to 7-year intervals, are necessary to achieve the long-term life of an asphalt pavement system. If the design and construction recommendations cannot be followed or anticipated traffic loads change considerably, we should be contacted to review our recommendations. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNN HOUSING AUTHORI7Y OFFICE BUILDING CTL I T JOB NO. 37,662 12 ~ SURFACE DRAINAGE Performance of foundations and concrete flatwork is influenced by moisture changes in the supporting materials. The risk of wetting foundation soils can be reduced by carefully planned and maintained surface drainage. Surface drainage should be designed to provide rapid runoff of surface water awayfrom the proposed building. We recommend thefollowing precautions be observed during construction and be maintained at all times after the construction is completed. 1. Wetting or drying of the open foundation excavation should be avoided. Positive drainage should be provided away from foundations. We recommend providing a minimum slope of at least 10 percent in the first 10 feet away from the foundations, where possible. In some cases we believe it is acceptable to decrease the required slope to about 5 to 7 percent, and design to achieve the recommended slope for most of the building. Pavements adjacent to the building should also slope to provide positive drainage away from the building. 3. Backfill around the foundation walls should be moisture treated and compacted to the criteria in the Fill and Backfill section. The potential for backfill settlement and the resultant distress to flatwork and utilities should be considered, as discussed in the Fill and Backfill section. 4. Roof downspouts and drains should discharge well beyond the limits of all backfill. Splash blocks and downspout extenders should be provided. Where drainage spills onto pavement, the pavement should be sloped to drain away from the building. 5. Landscaping should be carefully designed to minimize irrigation. Plants used close to foundation walls should be limited to those with low moisture requirements; irrigated grass should not be located within 5 feet of the foundation. Sprinklers should not discharge within 5 feet of foundations. Irrigation should be limited to the minimum amount sufficient to maintain vegetation; application of more water will increase the likelihood of slab and foundation movements. 6. Plastic membranes should not be used to cover the ground surface immediately surrounding the building. These membranes tend to trap HUMPHRIES POLI ARCHITECTS JEFFERSON COUNTY HOUSING AUTHORITY OFFICE BUILDING CTL I 7 JOB NO. 37,662 13 ~ moisture and prevent normal evaporation from occurring. Geotextile fabrics can be used to limit weed growth and allow for evaporation. LIMITATIONS Our borings were spaced to obtain a reasonably accurate picture of subsurface conditions. The borings are representative of conditions encountered only at the exact boring location. Variations in the subsurface conditions not indicated by our borings are possible. The placement and compaction of fill, backfill, subgrade and pavements should be observed and tested by a representative of our firm during construction. Foundation excavation andfooting installation should also be observed by a representative of our firm to verify that the subsurface conditions are as anticipated from our borings. We believe this investigation was conducted in a manner consistent with that level of skill and care normally used by geotechnical engineers practicing in this area at this time. No other warranty, express or implied, is made.

We recommend the proposed pavement be constructed in the following manner: 1. Subgrade should be stripped of organic matter, scarified, moisture treated, and compacted. Fills should be moisture treated to between optimum and 3 percent above optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASHTO T 99). 2. Utility trenches and all subsequently placed fill should be properly compacted and tested prior to paving. As a minimum, fill should be compacted to 95 percent of standard Proctor maximum dry density. 3. After final subgrade elevation has been reached and the subgrade compacted, the area should be proof-rolled with a heavy pneumatic- tired vehicle (i.e., a loaded 10-wheel dump truck). Subgrade that is pumping or deforming excessively should be scarified, moisture conditioned and compacted. 4. If areas of soft or wet subgrade are encountered, the material should be over-excavated and replaced with properly compacted backfill. Where extensive areas of soft, yielding subgrade are present, we recommend the excavation be inspected by a representative of our office. 5. Aggregate base course should be laid in thin, loose lifts, moisture treated to within 2 percent of optimum moisture content, and compacted to at least 95 percent of modified Proctor maximum dry density (ASTM D 1557, AASHTO T 180). 6. Asphaltic concrete should be hot plant-mixed material compacted to at least 95 percent of maximum Marshall density. The temperature at laydown time should be near235 degrees F. The maximum compacted lift should be 3.0 inches and joints should be staggered. 7. Subgrade preparation and the placement and compaction of all pavement materials should be observed and tested. Compaction criteria should be met prior to the placement of the next paving lift. The additional requirements of the Colorado Department of Transportation and the city of Wheat Ridge should apply. HUMPHRIES POLI ARCHITECTS JEFFERSON COUNN HOUSING AUTHORITY OFFICE BUILDING CTL I T JOB NO. 37,662 A-1 ~ RIGID PAVEMENT CONSTRUCTION RECOMMENDATIONS Rigid pavement sections are not as sensitive to subgrade support character- istics as flexible pavement. Due to the strength of the concrete, wheel loads from traffic are distributed over a large area and the resulting subgrade stresses are relatively low. The critical factors affecting the performance of a rigid pavement are the strength and quality of the concrete, and the uniformity of the subgrade. We recommend subgrade preparation and construction of the rigid pavement section be completed in accordance with the following recommendations: Natural soils should be stripped of organic matter, scarified, moisture treated, and compacted. We recommend the top one foot of the subgrade be moisture treated to between optimum and 3 percent above optimum moisture content. Soils should be compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASHTO T 99). Moisture treatment and compaction recommendations also apply where additional fill is necessary. 2. The resulting subgrade should be checked for uniformity and all soft or yielding materials should be replaced prior to paving. Concrete should not be placed on soft, spongy, frozen, or otherwise unsuitable subgrade. 3. The subgrade should be kept moist prior to paving. 4. Curing procedures should protect the concrete against moisture loss, rapid temperature change, freezing, and mechanical injury for at least 3 days after placement. Traffic should not be allowed on the pavement for at least one week. 5. Awhite, liquid membrane curing compound, applied atthe rate of 1 gallon per 150 square feet, should be used. 6. Construction joints, including longitudinal joints andtransverse joints, should be formed during construction or should be sawed shortly afterthe concrete has begun to set, but prior to uncontrolled cracking. All joints should be sealed. 7. Construction control and inspection should be carried out during the subgrede preparation and paving procedures. Concrete should be carefully monitored for quality control. The additional requirements of the city of Wheat Ridge and the Coloredo Department of Transportation Specifications should apply. The design section is based upon a 20-year period. Experience in the Denver area indicates virtually no maintenance or overlays are necessary for the design period. To avoid problems associated with scaling and to continue the strength gain, we recommend deicing salts not be used for the first year after placement.
