INTRODUCTION Terracon Environmental, Inc. (Terracon) has completed a Phase I Environmental Site Assessment (Phase I ESA) of the agricultural land located at County Road 26 and County Road 5 1/2 in Longmont, Colorado. This work was performed in general accordance with Terracon's proposal dated December 4, 1997. The Phase I ESA included the following tasks: • An on-site visual survey of the subject property, and cursory review of adjacent property, to observe for deleterious environmental conditions; • An interview with the site owners and contact with local government officials to obtain information indicating recognized environmental conditions associated with the property; and • A review of various records to help identify recognized environmental conditions in connection with the property. The purpose of the Phase I ESA was to accumulate data on present conditions and historical usage's of the subject and nearby property and the potential impact that these conditions and usage's may have had on the site. Terracon understands that Coldwell Banker will hereafter evaluate the significance of recognized environmental conditions as related to the proposed development of the subject property. 2. SITE DESCRIPTION The site location, geology and site reconnaissance are described in the following sections. 2.1 Location The subject site is located in north portion of Section 4, Township 2 North, Range 68 West of the 6th Principal Meridian, Boulder County, Longmont, Colorado. The subject property is bordered by agricultural property, associated farmhouses, outbuildings and residential property to the north, south, east, and west. A general site location map is provided as Figure 1 in Appendix A. The property's location is depicted in Figure 2 in Appendix A r- Proposed Meadow Vale North Subdivision Phase I ESA Project Number 43975066 Terracon December 31, 1997 Page 2 which is a portion of the United States Geological Survey (USGS) 7.5 minute series topographical map containing the site and surrounding area. A diagram of the subject property is included as Figure 3 Appendix A. The house and associated outbuildings on the extreme northwest corner of the site were excluded from this Phase I ESA per the request of Mr. Floyd Oliver, President of Meadow Vale Farm. According to Mr. Oliver, the house, outbuildings and adjacent property are being retained by the current occupant, and not included in the sale and development of the subject site. 2.2 Geology and Topography The following descriptions of regional geology of northeastern Colorado were obtained from the USGS. The geologic setting and surficial deposits are summarized in the remainder of this subsection. The subject site is located in the Colorado Piedmont section of the Great Plains physiographic province. The Colorado Piedmont was formed during the Late Tertiary and Early Quaternary geologic periods and is a broad erosional trench which separates the Southern Rocky Mountains from the High Plains. During the Late Mesozoic and Early Cenozoic periods, tectonic activity caused uplifting in the Front Range and downwarping of the Denver Basin located to the east. As the mountains rose, the land east of the Front Range subsided, forming the Denver Basin. The Denver Basin was a site of deposition for sediments eroded from the mountains, including the Arapahoe, Denver, and Dawson Formations. The subject site is located along the western flank of the Denver Basin. The present topography of the Colorado Piedmont in the region is characterized by relatively flat uplands and broad valleys. The Upper Cretaceous Arapahoe Formation consists of discontinuous beds of light gray to yellow-brown sandstone and claystone of terrestrial origin. The Denver Formation is highly variable in texture and composition, consisting of light gray to brown tufaceous silty claystone, tufaceous arkose, and andesitic conglomerates. These sediments were deposited on a gently sloping surface of low relief in a climate that was warmer and wetter than the present climate. The Cretaceous-Tertiary boundary is present in the lower portion of the Denver Formation. Southward, the Denver Formation merges into the Dawson Formation, which is similar to the Denver but is sandier and contains less volcanic materials. Both the Denver and Dawson Formations are loosely consolidated and become finer-grained and thinner eastward away from their source areas. In some parts of the Longmont area, bedrock appears at the surface and is covered by thin colluvium and residuum formed by in-situ weathering. However, most of the bedrock is covered by alluvial and eolian deposits to depths as great as 100 feet. Surficial 98J(34 r•' Proposed Meadow Vale North Subdivision Phase I ESA Project Number 43975066 Terracon December 31, 1997 Page 3 deposits in the vicinity of the project site consist of Upper Holocene Eolium. These deposits are as much as 15 feet thick but generally less than three (3) feet thick and consist of light-brown to reddish-brown to olive-gray windblown clay, silt, sand and granules. Surface drainage from the site, based on map contours and visual observations made by Terracon personnel at the time of the site visit, appeared to be directed east. Localized aquifers in this region occur in colluvial, landslide, windblown deposits, and in consolidated sedimentary rocks where rocks near land surface are fractured and weathered generally range from five (5) to 20 feet. Based on local topographic observations, the local drainage patterns and nearby surface water bodies, the groundwater flow direction near the site appears to be generally east towards the St. Vrain Creek. Installation and development of groundwater monitoring wells would be required to estimate a piezometric surface and groundwater flow direction for the site. 2.3 Site Reconnaissance The site reconnaissance was performed by Terracon personnel on December 22, 1997. As seen from Figure 3, the subject site is a square-shaped parcel located at County Road 26 and County Road 5 1/2 in Longmont, Colorado. The majority of the subject property was observed to be agricultural, and covered by the remains of harvested crops. Two (2) wood frame structures were noted near the extreme west portion of the site. The northernmost structure was reportedly occupied by tenants and observed around it was a propane tank, a clothesline, and a small pile of household trash. Access to the interior of this structure was not available at the time of the site visit. The south structure was badly charred and appeared to have burned down previously. Inside this structure burnt appliances, scraps of wood and metal, and several apparent paint cans destroyed by fire were observed. Stressed vegetation, pools of suspicious liquids, and strange odors were not observed on the subject property. The house and outbuildings adjacent to the northwest area of the subject site are being excluded from the Phase I ESA as previously discussed in Section 2.1. The houses and outbuildings were wood frame structures. Between the main house and surrounding the outbuildings was observed a recreational vehicle, a railroad car, a semi-trailer, apparent plumbing supplies, scraps of metal, several plastic and metal containers with unknown contents, numerous drums and barrels with unknown contents, a pile of pipe, and a large pile of branches, straw, and grass clippings. Two (2) aboveground storage tanks (ASTs) 980& '3V n. Proposed Meadow Vale North Subdivision Phase I ESA Project Number 43975066 Terracon December 31, 1997 Page 4 were observed south of the southwest outbuilding; the contents of which are unknown. Several automobile bodies were observed south of the group of outbuildings. One (1) of the outbuildings is reportedly a peacock coop. One (1) of the outbuildings was observed to contain a motorcycle, drums, and several approximately 10-gallon plastic containers. Access was not granted to the interior of the other buildings. Observations of other adjacent properties from the subject site and public vantage points were conducted for obvious indications of environmental impact. Adjacent properties and their usage are also shown on Figure 3. Farms and residential property were observed to the north, east, west, and south of the subject site. Railroad tracks were also observed to the west of the site. 3. INTERVIEWS Terracon personnel interviewed Mr. Bob Greene, the current property owner, by telephone on December 19, 1997. Mr. Greene has reportedly owned the subject property since approximately 1987. Mr. Greene reported that the use of the subject site and the surrounding properties has not changed since 1987. Mr. Greene was not aware of any grading/filling or any dumping on the subject property. He indicated that to his knowledge no one has stored or disposed of any hazardous substances on the site. To his knowledge, no USTs have been present on the subject site. He was not aware of any previous environmental site assessments done on the subject property 4. RECORDS REVIEW Terracon reviewed Federal and State database information provided VISTA Information Solutions, Inc. (VISTA) for indications of environmental concern in the vicinity of the subject property. Terracon also reviewed historical information provided by ENTRAC Corporation (ENTRAC). The database information is discussed in Sections 4.1 and 4.2. Historical information is discussed in Section 4.3. Listed below are the Federal and State databases which were searched and the date on which they were last updated. The search area encompassed distances up to 1.0 mile from the perimeter or 1.5 miles from the center of the site. Attached as Appendix B is the VISTA database information while the ENTRAC historical information is enclosed in Appendix C of this report. 9gaa34 Proposed Meadow Vale North Subdivision Phase I ESA Te'mcon Project Number 43975066 December 31, 1997 Page 5 DATABASE UPDATED RADIUS I (MILES) Federal Data NPL/Superfund Sites 4/97 1.5 CERCLIS/NFRAP Sites 4/97 1.0 RCRA TSD Facilities 4/97 1.0 RCRA Generators 4/97 0.625 RCRA Violation Sites 4/97 0.75 RCRA CORRACTS Sites 4/97 1.5 ERNS Hazardous Material Spills 3/97 0.625 TRIS Sites 12/96 0.75 State and Local Data SPUSuperfund Sites 10/96 1.5 Registered Under/Aboveground Storage Tanks 3/97 0.75 Leaking Underground Storage Tanks 4/97 1.0 Reported State Landfills 1/97 1.0 Colorado Spills 6/97 0.625 4.1 Federal Databases The following sections describe listings found in the Federal databases. 4.1.1 NPL Sites The National Priorities List (NPL) is EPA's database of uncontrolled or abandoned hazardous waste sites identified for priority remedial actions under the Superfund program. For inclusion on the NPL, a site must meet or surpass a predetermined hazard ranking score, or be chosen as a state's top-priority site, or meet all three (3) of the following criteria: • The United States Department of Health and Human Services issues a health advisory recommending that people be removed from the site to avoid exposure; • EPA determines that the site represents a significant threat; and • EPA determines that remedial action is more cost effective than removal action. VISTA did not identify NPL Superfund sites within a 1.5-mile radius of the subject site, based on their review of the April 1997 NPL listing. ggaa 34 p Proposed Meadow Vale North Subdivision Phase I ESAT erracon Project Number 43975066 December 31, 1997 Page 6 4.1.2 CERCLIS/NFRAP Sites The Comprehensive Environmental Response Compensation and Liability Information System (CERCLIS) is an EPA compilation of the sites which the EPA has investigated or is currently investigating for a release or a threatened release of hazardous substances pursuant to the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980; which is also known as the Superfund Act. In February 1995, the EPA designated approximately 25,000 CERCLIS sites as No Further Remedial Action Planned (NFRAP) and removed them from the CERCLIS database. NFRAP sites may be sites where, following an initial investigation, no contamination was found, contamination was removed quickly without the need for the site to be placed on the NPL, or contamination was not serious enough to require Federal Superfund action or NPL consideration. VISTA did not identify CERCLIS/NFRAP sites within a 1.0-mile radius of the subject site, based on their review of the April 1997 CERCLIS/NFRAP listings. 4.1.3 RCRA Facilities The Resource Conservation and Recovery Information System (RCRIS) database is an EPA compilation of reporting facilities that generate, store, transport, treat or dispose of hazardous waste. The EPA's Resource Conservation and Recovery Act (RCRA) Program identifies and tracks hazardous waste from the point of generation to the point of disposal. The RCRA facilities are divided into several categories, one (1) of which is treatment, storage and/or disposal facilities that are undergoing corrective action or have been issued a corrective action order (CORRACTS TSD). A corrective action order is issued when there has been a release of hazardous waste or constituents into the environment from a RCRA facility. Corrective actions may be required beyond the boundary of the designated facility and can be required regardless of when the release occurred, even if it predates RCRA. VISTA did identify one (1) RCRA CORRACTS TSD facility within a 1.0- mile radius of the subject site. The site is listed as McLane Project/Longmont Landfill in Section 8, Township 2 North, Range 68 West, and appears to be located 0.85 miles southwest and topographically crossgradient of the subject site. RCRA non-CORRACTS TSD facilities are those that treat, store and/or dispose of hazardous waste and currently are not or have not been under EPA investigation for a release or a suspected release of hazardous waste pursuant to the RCRA program. A RCRA non-CORRACTS TSD listing does not imply non-compliance with government regulations or that the facilities are/were polluting with hazardous wastes. VISTA did not identify RCRA non-CORRACTS TSD facilities within a 1.0-mile radius of the subject site. 9Yaa31-1 Proposed Meadow Vale North Subdivision Phase I ESA Terracon Project Number 43975066 December 31, 1997 Page 7 The other RCRA facilities include violation/enforcement, small quantity generator (SQG), and large quantity generator (LQG) sites. Facilities which have committed RCRA violations since 1980 or have had RCRA enforcement actions taken against them as RCRA violators are classified as RCRA Violation/Enforcement sites. Facilities which generate less than 1,000 kg of hazardous waste per month are classified as RCRA SQGs while facilities which generate more than 1,000 kg of hazardous waste per month are classified as RCRA LQGs. It is not uncommon for these types of facilities to be present in industrialized areas. If proper procedures are used in handling, utilizing and disposing of hazardous materials, environmental impairment liability threats from RCRA facilities should be low with respect to the subject property. However, if improper procedures are used with respect to hazardous materials, environmental impairment liability threats may exist and such a site may be listed as a RCRA CORRACTS TSD site. VISTA did not identify RCRA SQG, RCRA LQG or RCRA Violation facilities within the specified search radius of the subject site. The subject property was not listed by VISTA as a RCRA site. 4.1.4 ERNS Spill Sites VISTA conducted a search of the Emergency Response Notification System (ERNS) national database regarding notifications of spills and releases of hazardous materials. The ERNS is a standardized interagency system for handling of reports of spills and releases reported under the National Oil and Hazardous Substances Pollution Contingency Plan, CERCLA, SARA and Water Pollution Control Act. VISTA did not identify ERNS spill sites within the specified search radius of the subject site. 4.1.5 TRIS Sites VISTA conducted a search of the Toxic Release Inventory System (TRIS) national database regarding the toxic chemicals emissions inventory. The TRIS was established as part of the 1986 Emergency Planning and Community Right-to-Know Act (SARA) and requires the EPA to establish an inventory of toxic chemicals emissions from certain sites. VISTA did not identify TRIS sites within a 0.75-mile radius of the subject site based on their search of the December 1996 TRIS database. 4.2 State and Local Databases The following sections describe information obtained from State and local databases. 4.2.1 SPL Sites VISTA conducted a search of the State Priorities List (SPL) database regarding uncon- trolled or abandoned hazardous waste sites identified for priority remedial actions under 91OU 34 Proposed Meadow Vale North Subdivision Phase I ESA Project Number 43975066 Terracon December 31, 1997 Page 8 the Superfund program. The SPL database was provided by the Colorado Department of Public Health and Environment (CDPHE) Hazardous Material Waste Division and contains information similar to the Federal NPL database except at the state level only. VISTA did not identify SPL sites within a 1.5-mile radius of the subject site based on their review of two (2) SPL databases. 4.2.2 LUST Facilities State agencies maintain an inventory of leaking underground storage tanks (LUSTs) consisting of reported release locations. Those locations include closures where contamination was discovered or releases from spills, overfills and/or tank leaks were suspected or observed. VISTA did not identify LUST facilities within a 1.0-mile radius of the subject site. 4.2.3 Registered UST/AST Facilities The Colorado Department of Labor and Employment Oil Inspection Section (OIS) compiles an inventory of facilities with registered USTs and ASTs located in the state of Colorado. VISTA did not identify registered UST/AST facilities within an approximate 0.5-mile radius of the subject site. VISTA identified two (2) unmapped UST/AST facilities outside the specified search radius. The sites are listed as Country Corner at 7507 Hygiene Road in Hygiene, and Skips Place at 7511 Hygiene Road in Hygiene. These sites appear to be located several miles away from the subject site 4.2.4 Landfill Sites VISTA identified four (4) landfill sites within a 1.0-mile radius of the subject site. The sites listed appear to be the same site, and appear to be located 0.85 miles southwest and topographically crossgradient of the subject site. 1) Longmont Landfill Longmont, CO; 2) City of Longmont SWFD at 1998 West Highway 119; 3) Longmont Sanitary Landfill at 1998 West Highway 119; and 4) Longmont Disposal Site HWY 119. 4.2.5 Colorado Spill Sites VISTA conducted a search of the Colorado Spills database regarding notifications of spills and releases of hazardous materials. The Colorado Spills database was provided by the CDPHE and contains similar information as the national ERNS database except at the state level only. VISTA did not identify Colorado Spills site within the specified search radius. 9gaA34 r Proposed Meadow Vale North Subdivision Phase I ESA Project Number 43975066 Terracon December 31, 1997 Page 9 4.3 Historical and Local Information The following subsections contain historic information sources from VISTA's historical database. Historic information in the form of topographic (quadrangle) maps, and county planning maps was provided by VISTA. The information sources also include a review of the current topographic map and contact with local agencies. The ASTM Standard specifies that the property's use should be identified back to either 1940 or the first developed use whichever is earlier. Based upon historical maps provided by ENTRAC, the subject property appears to have been undeveloped as far back as approximately 1904. Information prior to 1904 was not readily available. 4.3.1 USGS Topographic Maps Terracon reviewed a variety of reproductions of quadrangle maps published by the USGS that had been included by ENTRAC as part of their historic records search. These maps may be useful in identifying the presence or absence of structures on or near the subject property. Quadrangle maps are titled according to a prominent city or landmark in the mapped area. The elevation of the subject property is approximately 4,900 to 4,940 feet above sea level. Longmont quadrangle maps dated 1968/79, 1968/71, 1968, 1961, 1950 and a Niwot quadrangle map dated 1904 and 1904/45 were provided by ENTRAC. Structures were observed on the northwest and west portions of the subject site, St. Vrain Creek was observed south and east of the subject site, and the Oligarchy Ditch was observed west of the subject site on the quadrangle maps reviewed by Terracon. 4.3.2 County Planning Maps Terracon reviewed a variety of reproductions of county planning maps included in the ENTRAC report as part of their historical records search. These maps may be useful in identifying the presence or absence of structures on or near the subject property. County planning maps dated 1969/80, 1965/79, 1969, 1947/56, and 1938/41 were provided by ENTRAC. Structures were observed on the northwest and west portions of the subject site on the county planning maps reviewed by Terracon. The St. Vrain Creek was observed to the south, and the Oligarchy Ditch was observed to the west of the subject site on the county planning maps reviewed by Terracon. Because of map resolution and the absence of landmarks, it is not always possible to distinguish whether the structures or surface features discussed above were present on the subject property. 9S. N3V Proposed Meadow Vale North Subdivision Phase I ESA Project Number 43975066 Terracon December 31, 1997 Page 10 4.3.3 Street Directories Street directories dated 1996 and 1989/90 were supplied by ENTRAC. The uses of the surrounding properties in the past appears consistent with the current uses according to the street directories supplied by ENTRAC. 4.3.4 Local Agencies As part of a Terracon Phase I ESA for Meadow Vale North Subdivision, Terracon contacted Mr. Mike Selan of the Longmont Fire Department in an effort to obtain additional information concerning properties located in the vicinity of that site. Mr. Selan was unaware of any past responses to the site. 5. CONCLUSIONS Terracon has completed a Phase I ESA in general accordance with the scope and limitations of ASTM Practice E 1527 of the square parcel located at County Road 26 and County Road 5 1/2 in Longmont, Colorado. The following conclusions are made based on information obtained during the completion of the Phase I ESA. 1. NPL, CERCLIS/NFRAP, RCRA NON-CORRACTS TSD, RCRA Violation, RCRA SQG, RCRA LQG, TRIS, ERNS SPL, UST/AST, and LUST sites were not identified within the specified search parameters of the subject site. 2. VISTA identified two (2) unmapped UST/AST facilities within the specified search parameters. The sites have Hygiene addresses and appear to be located several miles away from the subject site. 3. VISTA identified four (4) landfill listings within a 1.0-mile radius of the subject site. The listings listed appear to be the same site; Longmont Landfill at 1998 W. Highway 119; located approximately 0.85 miles southwest and topographically crossgradient of the subject site. 4. VISTA identified one (1) RCRA CORRACTS TSD site located within the specified search parameters. Listed as McLane Project/Longmont Landfill, the site appears to be located approximately 0.85 miles southwest and topographically crossgradient of the subject site. 5. The subject site appears to be agricultural land with associated farmhouses and outbuildings. Proposed Meadow Vale North Subdivision Phase I ESA Project Number 43975066 Terracon December 31, 1997 Page 11 6. Adjacent to the northwest area of the subject site were observed a house, outbuildings, numerous containers, barrels, drums, and two (2) ASTs. This area is not included in the Phase I ESA of the site and reportedly will be retained by the present occupant as part of the sale of the subject property. 6. RECOMMENDATIONS The following recommendations are made based on the information obtained during the completion of this Phase I ESA: 1. Based on the available information, Terracon does not suggest further investigation of the subject site at this time. 7. GENERAL COMMENTS Terracon has performed a Phase I ESA in general accordance with the scope and limitations of ASTM Standard E 1527 and with the scope of services in our proposal dated December 4, 1997. This report does not reflect any variations in subsurface stratigraphy, geohydrology, or contaminant distribution which may occur across the site. Actual subsurface conditions may vary and may not become evident without further exploration. Due to the dynamic nature of groundwater flow and contaminant migration, subsurface conditions will vary with time. This report has been prepared for the exclusive use of Coldwell Banker and Meadow Vale Farm for specific application as discussed. It has been intended as a limited assessment of the environmental conditions associated with the subject property and is prepared in accordance with generally accepted local assessment practices within the scope of the client's directives. No warranties, either express or implied, are intended or made. Terracon does not warrant the work of regulatory agencies or any third parties supplying information which may have been used during the assimilation of this report. The limitations of this assessment should be recognized as conclusions formulated on the environmental risks associated with this property. In the event that any changes in the nature or location of suspected sources of contamination as outlined in this report are observed, the conclusions and recommendations contained in this report shall not be valid unless these changes are reviewed and the opinions of this report are modified and verified in writing by Terracon. 986134/ F-' REFERENCES 1.

Report ID:439750460 Date of Report: December 4,1997 Version 2.5 Page#15 91Z 39 r APPENDIX C HISTORICAL INFORMATION 982x734/ 1! PROJECT HISTORICAL RECORDS SOURCES The ASTM Phase I Standard (E1527-97) allows discretion in choosing from among eight Standard Sources, plus "Other" non-specific sources. The Standard Sources are fire insurance maps, historical topos, street directories, aerial photos, property tax files, building department records, planning department records, and chain-of-title. The focus is on usage rather than ownership, which is why chain-of-title is not required and not sufficient by itself. The following searches were commissioned. Searches Comments ❑ Sanborn Fire Insurance Maps EYHistorical Topographic Maps '/County Planning Maps g Street Directories ❑ Other Searches EARLIEST DATE Historical research requirements were amended by ASTM in 1994. They now require identifying use back to either 1940 or first use (including agriculture), whichever is earlier. If this proves difficult, the "data failure" clause allows research to stop after reviewing all the Standard Sources that are reasonably ascertainable and likely to be useful. This search went back as far as possible using the commissioned sources. INTERVALS The ASTM amendment specifies that intervals shorter than roughly five years are not required, and longer intervals are acceptable if the specific use of the Property appears unchanged. Intervals were searched as close to five years as possible given the commissioned sources. SURROUNDING AREA The ASTM amendment clarifies that information on surrounding uses is a byproduct of researching the subject site. For example, a historical topo that covers the site will also show the surrounding area. This guideline was also followed.

BACKGROUND This collection covers the entire country and includes virtually every historical topo published by USGS in standard series since 1884. For urban sites, there may be twenty maps or more. For rural sites, there may only be one. Most sites have 5-10 maps going back to 1940 and before. The collection includes 7.5' series maps, as well as 15', 30', and smaller scale maps. Although newer 15' and 30' maps don't show much detail, early ones published before the introduction of the 7.5' series are quite useful. Photographic quads and orthophotoquads may also be included. A key to symbols typically used on these maps is presented on the back of this page. Some maps are reprints of early editions, published at a later date. For example, 30' editions from the 1800's were often reprinted several times before the corresponding 7.5' maps were introduced in the mid-1900's. These reprints occasionally show changes, but they don't seem to reflect a comprehensive update of the original map. SEARCH PROCEDURES The USGS map index is searched by latitude and longitude for standard 7.5', 15', 30', or 30' x 60' maps. Reprints of 15' and 30' maps are bracketed (i.e., the earliest and most recent version are copied). If the site is near the edge of the map (within roughly 1/8 mile), then the adjoining map is furnished at no extra charge (assuming the site is not unusually large, i.e. more than 400' across).

BACKGROUND Beginning in the 1930's, these maps were used by highway departments to disburse federal funding based on each county's road system. Some states just mapped roads, but many added cultural features such as farms and factories (see reverse for a key to symbols). These features were usually shown everywhere except inside city limits. • These maps are especially useful in conjunction with historical topographic maps. The topo can show the size, shape and location of structures, while the plan map can identify their use. One symbol may represent an operation with several structures. The USGS collection typically includes one edition, usually from the 1960's or 70's. It covers about half of the country. The private collection includes several additional editions for Colorado, beginning in the 1930's. Two dates are shown on many of the maps. The earlier date is when the map was originally drawn. The later date indicates when the road system was updated. Cultural features on these maps typically reflect the earlier date. SEARCH PROCEDURES A proprietary index is searched by county and city name. If no coverage is found, it may be possible to find obscure editions at county agencies, local libraries, or the state highway department. ❑ No relevant county planning map was found for this site. ❑ By 19_, the site was inside city limits (i.e., no features shown).

BACKGROUND These directories, also known as reverse phonebooks, list businesses and residents sorted by street address. The collection covers most developed areas of the Colorado Front Range, Grand Junction, and major Wyoming cities, going back in many cases to the 1920's and earlier. There are pitfalls inherent in the directories which this search attempts to overcome. For example, S. 19th St. may need to be searched under 19th, Nineteenth, and South. In some cases, directories were divided into poorly labeled sections or split up between suburbs. Street names, layouts, and numbering systems also changed over time. If such changes are noticed in the course of researching other sources (e.g., Sanborn maps), the search is modified accordingly and the change is noted on the back of this sheet. SEARCH PROCEDURES The private collection includes directories at roughly five year intervals. The search begins with the most recent directory and goes back to the earliest directory or until no coverage is found for the area. The search focuses on the subject site's street, plus up to five other streets that surround the site. The targeted streets, address ranges, and directories are listed on the back of this page. If no coverage was found, or if shorter intervals are necessary, additional directories may be available at the Denver Public Library, 1357 Broadway, and the Colorado Historical Society, 1300 Broadway. Local libraries or historical societies may also have coverage. ❑ No coverage was found in the private collection.

The site is located in the Northwest 1/4 of Section 4, Township 2 North, Range 68 West of the 6th Principal Meridian. The purpose of these services is to provide information and geotechnical engineering recommendations relative to: • subsurface soil and bedrock conditions • groundwater conditions • foundation design and construction • basement construction • floor slab design and construction • pavement design and construction • earthwork • drainage The conclusions and recommendations contained in this report are based upon the results of field and laboratory testing, engineering analyses, and experience with similar soil conditions, structures and our understanding of the proposed project. Supplemental geotechnical exploration and engineering analysis should be undertaken in order to develop final design parameters and to confirm or modify the conclusions and preliminary recommendations. PROPOSED CONSTRUCTION The site includes approximately 141 acres and will be developed for a residential subdivision. A total of 256 single-family residential lots and 89 patio home residential lots are currently planned for this subdivision. Development will include construction of site infrastructure and the construction of single-family residential structures. Major elements of site infrastructure will 1 9gaa3/ Geotechnical Engineering Exploration Terracor. Coldwell Banker Realty Project No. 22975176 include mass site grading, utility installation including sanitary sewer and water, and street construction. Design and construction of streets, with residential and collector designation requirements, are anticipated. Although final site grading plans were not available prior to the preparation of this report, mass grading is anticipated to bring the site to final construction grade. Fill placement is generally anticipated in portions of the site, the fill may be derived from borrow areas located in the other portions of the project area. Single-family residential construction is anticipated to include one- or two-story structures with partial or full depth basements. We anticipate that the superstructures will consist of wood- frames and be supported on reinforced concrete foundations. Continuous foundation loading of approximately 1 to 4 kips per lineal foot and column loads up to approximately 50 kips are anticipated. SITE EXPLORATION The scope of the services performed for this project included site reconnaissance by a geotechnical engineer, a subsurface exploration program, laboratory testing and engineering analysis. Field Exploration A total of 18 test borings were drilled on January 14 and 15, 1998 to depths of 15 to 20 feet at the locations shown on the Site Plan, Figure 1. All borings were advanced with a truck- mounted drilling rig, utilizing 4-inch diameter solid stem auger. The borings were located in the field by pacing from property lines and/or existing site features. Elevations were taken at each boring location by interpolation from contours indicated on the site plan. The accuracy of boring locations and elevations should only be assumed to the level implied by the methods used. Continuous lithologic logs of each boring were recorded by the geotechnical engineer during the drilling operations. At selected intervals, samples of the subsurface materials were taken by driving the California barrel sampler. Representative bulk samples of subsurface materials were obtained from pavement borings. Penetration resistance measurements were obtained by driving the California barrel into the subsurface materials with a 140-pound hammer falling 30 inches. The penetration resistance 2 Geotechnical Engineering Exploration Coldwell Banker Realty Terracon Project No. 22975176 value is a useful index to the consistency, relative density or hardness of the materials encountered. Groundwater measurements were made in each boring at the time of site exploration, and one (1) to two (2) days after drilling. Laboratory Testing All samples retrieved during the field exploration were returned to the laboratory for observation by the project geotechnical engineer, and were classified in accordance with the Unified Soil Classification System described in Appendix C. Samples of bedrock were classified in accordance with the general notes for Bedrock Classification. At that time, the field descriptions were confirmed or modified as necessary and an applicable laboratory testing program was formulated to determine engineering properties of the subsurface materials. Boring logs were prepared and are presented in Appendix A. Selected soil and bedrock samples were tested for the following engineering properties: • Water content • Grain size • Dry density • Plasticity Index • Swell/consolidation • R-Value • Compressive strength • Water soluble sulfate content Laboratory test results are presented in Appendix B, and were used for the geotechnical engineering analyses, and the development of foundation and earthwork recommendations. All laboratory tests were performed in general accordance with the applicable ASTM, local or other accepted standards. SITE CONDITIONS The site is currently open agricultural land consisting of fallow fields. The ground surface was generally flat and slopes to the east and southeast. Vegetation consisted of crop stubble and barren areas. Site drainage was generally to the east to southeast, although shallow depressions existed. Other site features include the Oligarchy Ditch that parallels the north edge of the property and is lined with large trees. A rural residence and associated outbuildings are located at the northwest corner of the property. Meadow Vale Farm Subdivision is located to the south of the site and open agricultural land and scattered residences surround the rest of the site. 3 9faa31 G Geotechnical Engineering Exploration Terracon Coldwell Banker Realty Project No. 22975176 SUBSURFACE CONDITIONS Geology The project area is located within the Colorado Piedmont section of the Great Plains physiographic province. The Colorado Piedmont, formed during Late Tertiary and Early Quaternary time (approximately 2,000,000 years ago), is a broad, erosional trench which separates the Southern Rocky Mountains from the High Plains. Structurally, the site lies along the western flank of the Denver Basin. During the Late Mesozoic and Early Cenozoic Periods (approximately 70,000,000 years ago), intense tectonic activity occurred, causing the uplifting of the Front Range and associated downwarping of the Denver Basin to the east. Relatively flat uplands and broad valleys characterize the present-day topography of the Colorado Piedmont in this region. Due to the relatively flat nature of the site, geologic hazards at the site are anticipated to be low. Seismic activity in the area is anticipated to be low; and from a structural standpoint, the property should be relatively stable. With proper site grading around proposed structures, erosional problems at the site should be minimal. Mapping completed by the Colorado Geological Survey (Hart, 1972), indicates the site in an area of "Moderate Swell Potential." Potentially expansive materials mapped in this area include bedrock, weathered bedrock and colluvium (surficial units). Soil and Bedrock Conditions As presented on the Logs of Boring, surface soils to depths of two (2) to 14 feet consisted of lean clays or sandy lean clays. The materials underlying the surface soils and extending to the maximum depth of exploration consisted of interbedded bedrock or claystone bedrock. Please refer to the Logs of Boring for more comprehensive strata descriptions. Field and Laboratory Test Results Field test results indicate that the clay soils vary from medium stiff to very stiff in consistency. The bedrock varies from weathered to very hard. 1Hart, Stephen S., 1972, Potentially Swelling Soil and Rock in the Front Range Urban Corridor, Colorado, Colorado Geological Survey, Environmental Geology No. 7. 4 9a2JJV r Geotechnical Engineering Exploration erracon Coldwell Banker Realty Project No. 22975176 Laboratory test results indicate that the clay subsoils at shallow depth have non- to low expansive potential. The dry density of the clays varied between 97 to 108 pcf at moisture contents ranging form 18 to 27 percent. Unconfined compressive strength of clay samples tested varied from 1,300 to 9,500 psf. Atterberg Limits tests performed on selected clay samples indicated Liquid Limits ranging from 40 to 46, Plasticity Indices ranging from 18 to 24 with a range of 70.5 to 88.5 percent fines (material passing the NO. 200 sieve). Swell- consolidation test results indicate that the bedrock is non-to low in expansive potential. Groundwater Conditions Groundwater was encountered at depths of five (5) to 18% feet in the test borings at the time of field exploration. When checked one (1) to two (2) days after drilling, groundwater was measured at depths of four and one-half (4%) to 14 feet. These observations represent only current groundwater conditions, and may not be indicative of other times, or at other locations. Groundwater levels can be expected to fluctuate with varying seasonal and weather conditions. Based upon review of U.S. Geological Survey Maps (2Hillier, et al, 1983), regional groundwater beneath the project area predominates in colluvial, landslide or windblown materials, or in fractured weathered consolidated sedimentary bedrock located at a depth near ground surface. Seasonal variations in groundwater conditions are expected since the aquifer materials may not be perennially saturated. Groundwater is generally encountered at depths ranging from 5 to 20 feet below ground surface; depth to seasonal groundwater is generally 10 feet or less. Zones of perched and/or trapped groundwater, where not already present, may also occur at times in the subsurface soils overlying bedrock, on top of the bedrock surface or within permeable fractures in the bedrock materials. The location and amount of perched water is dependent upon several factors, including hydrologic conditions, type of site development, irrigation demands on or adjacent to the site, fluctuations in water features, and seasonal and weather conditions. Fluctuations in groundwater levels can best be determined by implementation of a groundwater monitoring plan. Such a plan would include installation of groundwater monitoring wells, and periodic measurement of groundwater levels over a sufficient period of time. The possibility of groundwater fluctuations should be considered when developing design and construction plans for the project. 2Hillier, Donald E.; Schneider, Paul A., Jr.; and Hutchinson, E. Carter, 1983, Depth to Water Table (1979) in the Boulder-Fort Collins-Greeley Area, Front Range Urban Corridor, Colorado, United States Geological Survey, Map I-855-I. 5 0 Geotechnical Engineering Exploration Terracon Coldwell Banker Realty Project No. 22975176 CONCLUSIONS AND RECOMMENDATIONS Geotechnical Considerations Based upon the geotechnical conditions encountered in our test borings, the site appears suitable for the proposed construction. We believe that the primary geotechnical conditions which will influence development of the site and/or foundation, floor slab and pavement construction is the presence of the near surface bedrock which has variable swelling characteristics and shallow groundwater encountered on portions of the property. Other geotechnical concerns include the high moisture clay soils which will compress to some extent when loaded. Soft, wet clay soils may require some method of soil stabilization prior to pavement or foundation construction. In addition, when fills are placed over the clay soils, they will compress and consolidate to some degree. Our experience suggests that for shallow fills the resulting settlements will occur within a relatively short time after grading is complete, and should not significantly affect the proposed development or other site improvements. For deeper fills, it is possible that excessive settlements may occur. We should review site grading plans to evaluate whether further investigation and/or analysis is necessary to address this concern. We believe that problems associated with these concerns can be mitigated with proper planning during site development, design and construction. These concerns and other site development considerations are briefly discussed in the following sections. Shallow groundwater will limit the depth of basement construction and in some areas, depending upon final site grades, may preclude the use of basements. The primary methods which can be used to mitigate the impact of shallow groundwater on the site could include limiting the depth of below grade construction, raising the site with structural fill to increase the depth to groundwater or installing area underdrain systems to provide a means to control, and in some instances, to lower existing water levels. Where practicable, we recommend the grading plans be designed so that basement floors will be at least 3 feet above the level of the groundwater. In addition, grading plans should be designed so that the final street subgrade is at least 3 feet above the groundwater surface. Preliminary Foundation Recommendations Due to the presence of non- to low-swelling clays and variable bedrock on the site, spread footing foundations bearing upon undisturbed subsoils and/or engineered fill are recommended for support for the proposed structures throughout a majority of the site, more specifically in areas of Test Borings 1 to 11. Footings that are placed on the clay soils may be preliminarily designed for a maximum bearing pressures ranging from 1,000 psf to 2,000 psf. Footings that are placed upon the bedrock materials may be preliminarily designed for maximum bearing 6 q a 3I I Geotechnical Engineering Exploration Terracon Coldwell Banker Realty Project No. 22975176 pressures ranging from 2,500 to 3,000 psf. In addition the footings that are placed upon the bedrock materials should be preliminarily designed to maintain minimum dead load pressures ranging from 800 to 1,000 psf. In order to maintain the minimum dead-load pressure, it may be necessary to design and construct a system of grade beams and isolated footing pads. Depending upon the area, soil/material characteristics and groundwater levels portions of the site may have to be designed for a pad and grade beam foundation system. Areas of compressible/soft soils may be encountered at foundation bearing depth. Soft soils should be removed to minimum depths as indicated by the project geotechnical engineer. Soft soils should be replaced with lean concrete, engineered fill or gravel. Foundation excavations should be observed by the geotechnical engineer. If the soil conditions encountered differ from those presented in this report, supplemental recommendations will be required. Supplemental geotechnical exploration and engineering analysis should be undertaken in order to develop final design parameters and to confirm or modify the conclusions and preliminary recommendations. Basement Construction Groundwater was encountered at depths of about four and one-half (4Y:) to 14 feet in all of our test borings. In particular, shallow ground water (less than 8 feet below the surface) was measured in our Test Borings 1, 3, 4, 6, 7, 8, 10, 14, 15, and 18. In addition, perched groundwater, where not already present, may occur at times since the subsurface soils are relatively impermeable and tend to trap water. Shallow groundwater will limit the depth of basement construction and in some areas, depending upon final site grades, may preclude the use of full-depth basements. Where practicable, we recommend the grading plans be designed so that basement floors will be at least three (3) feet above the level of the groundwater. Foundation drains will be necessary around all basement areas. Where groundwater is encountered within three (3) feet of lower level floors, the drain system should, at a minimum include an underslab gravel layer sloped to an interior perimeter drain. Where groundwater is at least three (3) feet below the lower level floors, an exterior drain bedded in free draining gravel should be sufficient. Site specific perimeter drainage system details can be provided following supplemental geotechnical exploration. Floor Slab Design and Construction Subsoils at the site consist of either non-expansive to very low swelling clays or moderately expansive bedrock. Based on the physical properties of the clays and bedrock and on our experience, however fill derived from these materials will be non-expansive or have low swell 7 9832734i 4i Geotechnical Engineering Exploration Terracon Coldwell Banker Realty Project No. 22975176 potential if it is moisture conditioned and compacted at or near optimum moisture content. We judge that fill derived from the claystone bedrock could have moderate swell potential if it is moisture conditioned and compacted at optimum moisture content or above. The properties of site grading fill will affect the performance and design and construction recommendations of slabs-on-grade at the site. Where non-expansive or low swelling clay is encountered in the excavation and expansive bedrock is well below the floor level, we believe that conventional slab-on-grade construction is feasible. The builder/owner should recognize that slabs constructed on low swelling soils could heave and crack to some degree if the underlying soils become wetted. To our knowledge, the only reliable solution to eliminate floor heave, cracking and possible structural damage is the use of structural floors supported independent of the subgrade soils. We recommend the use of a structural floor with a void beneath it for finished basement areas where moderate or higher swelling soils/bedrock are encountered at or near the level of the floor. The builder/owner may elect to use slab-on-grade construction for unfinished basements where moderate or lower swelling materials are present provided they recognize and are willing to assume the risk that slab performance may not be reasonable in some instances. Swell potential should be more thoroughly defined on each lot during design level geotechnical explorations. Pavement Design and Construction Design of pavements for the project have been based on the procedures outlined in the 1986 Guideline for Design of Pavement Structures by the American Association of State Highway and Transportation Officials (AASHTO). Traffic criteria used for pavement thickness designs include equivalent 18-kip single axle loads (ESAL's) of 30 for minor collectors/boulevards, 5 for local low-volume residential streets, and 2%for private drives and alleys. For flexible pavement design, a terminal serviceability index of 2.0 was utilized along with an inherent reliability of 75% and a design life of 20 years. Using a design R-value of five (5) determined in the laboratory and our experience with similar soils, appropriate ESAL/day, environmental criteria and other factors, the structural numbers (SN) of the pavement sections were determined on the basis of the 1986 AASHTO design equation. 8 980161.,/ 07. Geotechnical Engineering Exploration Terracon Coldwell Banker Realty Project No. 22975176 Recommended alternatives for flexible pavements are summarized as follows: Recommended Pavement Thickness (inches) Asphalt Aggregate Traffic Area Alternative Concrete Base Total Surface Course Collectors/ A 7 7 Boulevards B 4 12 16 Local A 512 512 Residential B 3 10 13 Drives and A 5 5 Alleys B 3 7 10 Some relatively high moisture content, plastic clays were encountered on the site. These conditions could result in "pumping" subgrade soils which may require stabilization. Where subgrade stabilization is required, alternative treatments would include the use of granular pit- run materials, crushed concrete and/or geotextiles or geogrids, or chemical treatment. The pavement sections presented herein are based, in part, on design parameters selected by Terracon based on experience with similar projects and soils conditions. Design parameters such as design life, terminal serviceability index and inherent reliability may vary with specific project requirements. Variation of these parameters may change the thickness of the pavement sections presented. Terracon is prepared to discuss the details of these parameters and their effects on pavement design and reevaluate pavement design as appropriate. Aggregate base course (if used on the site) should consist of a blend of sand and gravel which meets strict specifications for quality and gradation. Use of materials meeting Colorado Department of Transportation (CDOT) Class 5 or 6 specifications is recommended for base course. Aggregate base course and select subbase should be placed in lifts not exceeding six inches and should be compacted to a minimum of 95% Standard Proctor Density (ASTM D698). Asphalt concrete and/or plant-mixed bituminous base course should be composed of a mixture of aggregate, filler and additives, if required, and approved bituminous material. The bituminous base and/or asphalt concrete should conform to approved mix designs stating the Marshall or Hveem properties, optimum asphalt content, job mix formula and recommended mixing and placing temperatures. Aggregate used in plant-mixed bituminous base course and/or asphalt concrete should meet particular gradations. Material meeting Colorado Department of Transportation Grading C or CX specification is recommended for asphalt concrete. Aggregate meeting Colorado Department of Transportation Grading G or C specifications is recommended 9 Geotechnical Engineering Exploration Terracon Coldwell Banker Realty Project No. 22975176 for plant-mixed bituminous base course. Mix designs should be submitted prior to construction to verify their adequacy. Asphalt material should be placed in maximum 3-inch lifts and should be compacted to a minimum of 95% Marshall or Hveem density (ASTM D1559) (ASTM D1560). The performance of all pavements can be enhanced by minimizing excess moisture which can reach the subgrade soils. The following recommendations should be considered at minimum: • Site grading at a minimum 2% grade away from the pavements; • Compaction of any utility trenches for landscaped areas to the same criteria as the pavement subgrade; • Sealing all landscaped areas in or adjacent to pavements to minimize or prevent moisture migration to subgrade soils; • Placing compacted backfill against the exterior side of curb and gutter; and, • Placing curb, gutter and/or sidewalk directly on subgrade soils without the use of base course materials. General Site Grading Recommendations/Earthwork The ground surface in the area of proposed fill placement should be stripped of vegetation and organic matter. This material should be wasted from the site or stockpiled and used to revegetate landscape areas or exposed slopes after completion of grading operations. If it is necessary to dispose of organic materials on-site, they should be placed in non-structural areas and in fill sections not exceeding 5 feet in height. For permanent slopes in compacted fill or cut areas we recommend slopes of 3:1 (horizontal to vertical), or less to reduce erosion and maintenance problems. If steeper slopes are required for site development, stability analyses should be completed to design the grading plan. The subgrade beneath proposed fill and pavement areas should be scarified, moisture conditioned within 2 percent of optimum moisture content and compacted to at least 95 percent of the standard Proctor maximum dry density (ASTM D 698). For shallow groundwater areas of the site, we recommend limiting cuts during final grading operations and setting the basement floors as high as practicable to reduce the impact of shallow groundwater and the comparatively soft clay soils on the proposed construction. Where practicable, we recommend the grading plans be designed so that basement floors will be at least 3 feet above the level of the groundwater. In addition, grading plans should be designed so that the final street subgrade is at least 3 feet above the groundwater surface. 10 Geotechnical Engineering Exploration Terracon Coldwell Banker Realty Project No. 22975176 Conventional rubber-tired earthmoving equipment may encounter soft soils and/or severe pumping due to repetitive construction traffic loads, particularly in cut areas. For this reason, the use of light-weight earthmoving equipment may be needed to reduce the potential of "pumping" subgrade soils. Where possible, every effort should be made to minimize construction traffic in soft clay areas of the site. Some subgrade stabilization may be needed prior to fill placement or pavement construction. Stabilization techniques could include the use of import granular materials and/or geogrids or geotextiles. Chemical stabilization could also be considered for stabilization. Final site grading plans should be prepared with due consideration given to the potential constraints and/or potential construction/design difficulties associated with shallow groundwater, comparatively soft clay soils and swelling bedrock materials. The on site clay soils or approved low swelling import materials can be used for site grading fill. The properties of the fill will affect the performance of foundations, slabs-on-grade and pavements. Selective grading should be considered where practicable to reduce the potential for increased foundation and or slab construction costs as a result of grading operations. For instance, potentially expansive materials (such as claystone) should not be used for site grading fill where swelling soils/bedrock do not presently exist or if the claystone has to be used, it should be placed in the bottom portion of deep fills. The fill should be placed in thin, loose lifts and compacted. Spreading and "wind-rowing" of wet soils or moisture addition and uniform mixing of dry soils will be necessary to bring the soils into working moisture ranges and will be important. We recommend fill placed at the site be moisture conditioned within 2 percent of optimum moisture content and compacted to at least 95 percent of the standard Proctor maximum dry density (ASTM D 698). Sloping areas steeper than 5:1 (horizontal:vertical) which will receive fill should be benched to reduce the potential for slippage between existing slopes and fills. Fill should not contain frozen material and it should not be placed on a frozen subgrade. Placement and compaction of fill should be observed and tested by the geotechnical engineer to verify that the specified moisture and compaction requirements have been achieved. Utility Construction Excavations into the on-site soils/bedrock will encounter a variety of conditions. Excavations into the clays and bedrock above groundwater can be expected to stand on relatively steep temporary slopes during construction. However, caving, wet soils and groundwater depending upon depth of excavation will also be encountered and these conditions will require flatter slope inclinations. The individual contractor(s) should be made responsible for designing and constructing stable, temporary excavations as required to maintain stability of both the excavation sides and bottom. All excavations should be sloped or shored in the 11 98:9°13/ Geotechnical Engineering Exploration Coldwell Banker Realty Terracon Project No. 22975176 interest of safety following local, and federal regulations, including current OSHA excavation and trench safety standards. As a safety measure, it is recommended that all vehicles and soil piles be kept to a minimum lateral distance from the crest of the slope equal to no less than the slope height. Based on the groundwater conditions encountered it appears that some method of temporary dewatering will be required on portions of the site during placement of the pipe and during backfilling operations. We believe that most of the bedrock materials can be excavated with either heavy duty trenchers or large backhoes. Very hard bedrock layers may be encountered which could require drilling and blasting to advance excavations. All piping should be adequately bedded for proper load distribution and to prevent damage during compaction operations. Backfill should consist of the on-site soils or existing bedrock. If bedrock is used, all plus 6-inch material should be removed from it prior to its use. Utility trench backfill should be moisture conditioned within 2 percent of optimum moisture content and should be compacted to at least 95 percent of the standard Proctor maximum dry density (ASTM D698). The soils to be penetrated by the proposed excavations may vary significantly across the site. The preliminary soil classifications are based solely on the materials encountered in widely spaced exploratory test borings. The contractor should verify that similar conditions exist throughout the proposed area of excavation. If different subsurface conditions are encountered at the time of construction, we recommend that we be contacted immediately to evaluate the conditions encountered. GENERAL COMMENTS Supplemental geotechnical exploration and engineering analysis should be undertaken in order to develop final design parameters and to confirm or modify the conclusions and recommendations contained in this report. It is recommended that the Geotechnical Engineer be retained to provide a general review of final design plans and specifications in order to confirm that grading and preliminary foundation recommendations have been interpreted and implemented. In the event that any changes of the proposed project are planned, the conclusions and recommendations contained in this report should be reviewed and the report modified or supplemented as necessary. The Geotechnical Engineer should also be retained to provide services during excavation, grading, foundation and construction phases of the work. Supplemental geotechnical 12 g8da35� Geotechnical Engineering Exploration Coldwell Banker Realty Terracon Project No. 22975176 exploration is recommended once final building locations and site configurations have been established to determine site specific geotechnical conditions. Observation of foundation excavations should be performed prior to placement of reinforcing and concrete to confirm that satisfactory bearing materials are present and is considered a necessary part of continuing geotechnical engineering services for the project. Construction testing, including field and laboratory evaluation of fill, backfill, pavement materials, concrete and steel should be performed to determine whether applicable project requirements have been met. It would be logical for Terracon Consultants Western, Inc. to provide these additional services for continuing from design through construction and to determine the consistency of field conditions with those data used in our analyses. The analyses and recommendations in this report are based in part upon limited data obtained from the field exploration and should be considered preliminary in nature. The nature and extent of variations beyond the location of test borings may not become evident until construction. If variations then appear evident, it may be necessary to re-evaluate the recommendations of this report. Our professional services were performed using that degree of care and skill ordinarily exercised, under similar circumstances, by reputable geotechnical engineers practicing in this or similar localities. No warranty, express or implied, is made. We prepared the report as an aid in the preliminary design of the proposed project. This report is not a bidding document. Any contractor reviewing this report must draw his own conclusions regarding site conditions and specific construction techniques to be used on this project. This report is for the exclusive purpose of providing geotechnical engineering and/or testing information and recommendations. The scope of services for this project does not include, either specifically or by implication, any environmental assessment of the site or identification of contaminated or hazardous materials or conditions. If the owner is concerned about the potential for such contamination, other studies should be undertaken. 13 91x)35/ `_ oun/TY &ago �4- — _ _ •_ _ •• 1-••• ■ ' . ..r...(..I.---V,I5P'''C-E Th17 r I T', 41 44 .TB-244 `} E-J • 4e 4 4d L TB-3 } 35 34133 3x 31 S ■ S 44 4 U 4v 31 i8 3l G- 2q • •1 rl / \, - 7 ILL 1`�/ -��..

The sediments may be composed of particles of pre-existing rocks derived by mechanical weathering, evaporation or by chemical or organic origin. The sediments are usually indurated by cementation or compaction. Chert Very fine-grained siliceous rock composed of micro-crystalline or crypto- crystalline quartz, chalcedony or opal. Chert is various colored, porous to dense, hard and has a conchoidal to splintery fracture. Claystone Fine-grained rock composed of or derived by erosion of silts and clays or any rock containing clay. Soft massive; gray, black, brown, reddish or green and may contain carbonate minerals. Conglomerate Rock consisting of a considerable amount of rounded gravel, sand and cobbles with or without interstitial or cementing material. The cementing or interstitial material may be quartz, opal, calcite, dolomite, clay, iron oxides or other materials. Dolomite A fine-grained carbonate rock consisting of the mineral dolomite ECaMg (CO3)2). May contain noncarbonate impurities such as quartz, chert, clay minerals, organic matter, gypsum and sulfides. Reacts with hydrochloric acid (HCL). Limestone A fine-grained carbonate rock consisting of the mineral calcite (CaCo3). May contain noncarbonate impurities such as quartz, chert, clay minerals, organic matter, gypsum and sulfides. Reacts with hydrochloric acid (HCL). Sandstone Rock consisting of particles of sand with or without interstitial and cementing materials. The cementing or interstitial material may be quartz, opal, calcite, dolomite, clay, iron oxides or other material. Shale Fine-grained rock composed of, or derived by erosion of silts and clays or any rock containing clay. Shale is hard, platy, or fissile may be gray, black, reddish or green and may contain some carbonate minerals (calcareous shale). Siltstone Fine grained rock composed of, or derived by erosion of silts or rock containing silt. Siltstones consist predominantly of silt sized particles (0.0625 to 0.002 mm in diameter) and are intermediate rocks between claystones and sandstones, may be gray, black, brown, reddish or green and may contain carbonate minerals. lierracon 9W31 Hello
