PURPOSE ,AND SCOPE OF STUDY

This report presents the results of a subsurface exploration program to provide foundation

recommendations for the proposed residence to be located on a parcel of land known as Lot 13,

Block 2, Pole Creek Meadows Subdivision, located in Grand County, Colorado. The project site

is shown in Figure 1. In addition to the soil and foundation investigation, percolation tests were

performed to develop recommendations for the individual sewage disposal system for the

proposed residence.

A field exploration program was conducted in order to obtain information regarding the

subsurface conditions. Material samples obtained during the subsurface investigation ' were

tested in the laboratory to provide data on the classification and engineering characteristics of the

on-site soils. The results of the field and laboratory investigations are presented herein.

This report has been prepared to summarize the data obtained and to present our conclusions and

recommendations based on the proposed construction and the subsurface conditions encountered.

Design par~meters and a discussion of the geotechnical engineering considerations related to the

construction of the proposed residence are included.

PROPOSED CONSTRUCTION

The proposed construction at the site consists of a five-bedroom, single family residence with a

walkout basement. Basecj on the information provided, we anticipate that structure loadings will

be light, typical of residential construction. The amount of site grading required for construction

appears to be moderate given the grade of the site.

If the project features or loadings differ significantly from those above, we should be contacted

to reevaluate the recommendations contained herein.

SITE CONDITIONS

The project site is accessed by County Road 5221 in Grand, County, Colorado. The site was

vegetated with sparse alpine grasses 'and evergreen trees. The site exhibited a gentle slope to the

I

west of approximately 3 to 5 degrees.

Pole Creek Meadows

Lot 13, Block 2

Grand County

The subsurface conditions are described as follows:

Topsoil: brown and humic in composition.

Sand and Clay: occasionally gravelly, fine to coarse grained, low plastic, medium dense, slightly

moist, and light brown in color.

Sand: clayey to gravelly, fine to coarse grained, low plastic, medium dense, slightly moist, and

light brown in color.

Interbedded sandstone/claystone bedrock: blocky, occasionally silty, fine to coarse grained,

medium dense to hard, slightly moist and light brown in color.

Graphic logs of the test pits are shown in Figure 2. Groundwater was not encountered in the test

pits at the time of our investigation, however fluctuations can occur depending on seasonal

precipitation, irrigation and other factors.

Swell-consolidation tests were performed on random selected samples of the sandstonelclaystone

bedrock. The result obtained indicated the material exhibited a negligible to low swell

expansion characteristic ranging from 0.0 to 0.4 percent under a surcharge of 1000 psf.

FOUNDATION RECOMMENDATIONS

Considering the subsurface conditions encountered on-site and the nature of the proposed

construction, we recommend that the residence be founded on spread footings placed on

undisturbed natural soils or bedrock.

The design and construction criteria presented below should be observed for a spread footing

foundation system.) The construction details should be considered when preparing project

documents.

1) Footings placed on undisturbed natural soils may be designed for an allowable soil bearing

pressure of 2,000 psf.

2) Spread footings should have a minimum-footing dimension of 12 inches.

Job No. 99- 1073 Ground Engineering Consultants, Inc. Page 3

Pole Creek Meadows

Lot 13, Block 2

Grand County

3) Exterior footings shall be provided with adequate soil cover above their bearing elevation for

frost protection. Placement of the bottom of the footings at least 3. 5 feet below exterior

grade is considered adequate soil cover in this area.

4) The lateral resistance of spread footing foundations placed on undisturbed 'natural soils will

be developed as the sliding resistance of the footing on the foundation materials. Sliding

friction at the bottom of the footings of the footings can be taken as 0.4 times the vertical

dead load.

5) Continuous foundation walls should be reinforced top and bottom to span an unsupported

length of at least 10 feet.

6) Based on. experience, we estimate total settlement for footing design and construction will be

approximately 1 inch or less.

7) It appears the foundation excavation may be performed with a conventional rubber tire

backhoe. A heavy-duty track backhoe will lIkely be needed to perform the excavation if

more competent bedrock is encountered.

8) Care should be taken when excavating the foundations to avoid disturbing the supporting

materials. All disturbed areas below the bottom of the footings must be recompacted to a

least 95% of the modified Proctor density (ASTM D- 1557).

9) A representative of the soil engineer shall observe all footing excavations prior to concrete

placement.

FOUNDATION WALLS

Foundation walls which are laterally supported and can be expected to undergo a minimal

amount of deflection (" at-rest" condition) may be designed for a lateral earth pressure computed

on the basis of an equivalent fluid uIlit weight of 65 pcf for onsite or imported, non-expansive,

granular material.

All foundation walls should be designed for appropriate hydrostatic and surcharge pressures such

as adjacent buildings, traffic, and construction materialS and equipment. The pressures

recommended above assume a relatively horizontal backfill surface.

Job No. 99- 1073 Ground Engineering Consultants, Inc. Page 4

Pole Creek Meadows

Lot 13, Block 2

Grand County

The onsite excavated granular materials may be used as foundation wall backfill. Backfill should

be carefully placed in uniform lifts and properly compacted near optimum moisture. content.

Care should be taken not to overcompact the backfill sil1ce this could cause excessive lateral

pressure on the walls. Some settlement of deep foundation wall backfill will occur even if the

material is placed correctly.

FLOOR SLABS

The natural on-site granular soils, exclusive of topsoil, are suitable to support lightly to

moderately loaded slab-on-grade construction. -Floor slabs should be provided with control joints

to reduce damage that may occur as a result of shrinkage cracking. Additionally, the slabs should

be adequately reinforced. We suggest the spacing be provided on the order 9f 12 feet centers.

The actual joint spacing should be based on the slab design.

A minimum 4- inch layer of free draining gravel should be placed beneath the floor slabs. This

material should consist of aggregate meeting the gradation criteria of No. 57 or No. 67 concrete

aggregate as defined by the Colorado Department of Transportation standard specifications. The

granular layer will help distribute floor slab loadings and aid in drainage.

WATER-SOLUBLE SULFATES

The concentration of water-soluble sulfates I!leasured in samples obtained from the exploratory

pits returned values of 0.06 percent. This concentration of water-soluble sulfates represents a

negligible degree of sulfate attack in concrete exposed to these materials. The degree of attack is

based in a range of negligible, moderate, severe, and very severe as presented in the " Design and

Control Mixtures" presented by the Portland Cement Association.

Based on this information, we believe special sulfate resistant cement will not be required for

concrete exposed to the on-site materials.

SURFACE DRAINAGE

The following drainage precautions should be observed during the construction and maintained

at all times after the residence has been completed.

1) Excessive wetting or drying of the foundation excavations and underslab areas should be

avoided during construction.

Job No. 99- 1073 Ground Engineering Consultants, Inc. Page 5

Pole Creek Meadows

Lot 13, Block 2

Grand County

2) The ground surface surrounding the exterior of the buildings should be sloped to drain away

from the foundation in all directions. We recommend a minimum slope of 12 inches in the

first 10 feet.

3) Roof downspouts and drains should discharge well beyond the limits of the backfill.

4) Landscaping which requires excessive watering should be located at least 10 feet from the

house.

5) Plastic membranes should not be used to cover the ground surface adjacent to the foundation

walls.

UNDERDRAIN SYSTEM

The lower level of the structure should be prote~ted by an underdrain system. Groundwater was

not encountered, but due to the quantity of snow melt and slope of the site, our experience

indicates that these conditions can result in the saturation of the surface soils for an extended

period of time.

The underdrain system should be placed at least 12 inches below the floor slab and consist of

drain pipe, free-draining gravel, and filter fabric. Free-draining gravel used in the drain system

should contain less than 5 percent passing the No. 200 sieve and more than 50 percent retained

on the No. 4 sieve, and have a maximum size of 2 inches. The 4- inch perforated PVC drainpipe

should be surrounded on the sides with a minimum of 6 inches of free-draining gravel with the

granular materials extending upward outside grade beam to a level above the void form. The

gravel and drain pipe should be underlain with plastic sheeting glued to the foundation wall in

order to reduce moisture infiltration. A filter fabric should be placed on top of the gravel in

order to reduce migration of fines into the drain system. The pipe should be graded at a

minimum slope of 1 percent to multiple sumps where water can be removed by pumping or

gravity discharge.

SEPTIC SYSTEM RECOMMENDATIONSIPERCOLATION TEST RESULTS

Percolation tests were performed in accordance with applicable county and' state requirements in

the granular materials. The average percolation rate in these soils was found to be 21 minutes

per inch. This percolation rate falls within the allowable range ( 5 minutes per inch to 60 minutes

per incli) for conventional absorption fields. Percolation tests were conducted in accordance with

applicable county and state requirements. The percolation test data is shown in Appendix A

For the proposed S- bedroom residence, we have calculated a peak flow for design of 1, 800

gallons per day. The sewage volume calculations are shown in Appendix A The septic tank

should have a capacity of at least 1, SOO gallons per EPA and State Department of Health

guidelines. A typical septic tank cross section' is shown in Figure 4. A conventional gravel

absorption bed system, as shown in Figures Sand 6, shall cover a minimum area of 1, 972 square

feet. A chambered system such as the Infiltrator system may be used in lie!} of a conventional

gravel absorption system. The chambered system should also cover a minimum area of 1, 282

square feet. Installation should be in accordance with the manufacturer' s recommendations and

the system should consist of a minimum of 83 infiltrators for chambers measuring lS.5 square

feet per chamber.

A minimum of five feet of existing overburden or import granular material approved by the soils

engineer must be maintained between the bottom of the absorption field and the top of

sandstone/claystone bedrock. Depending on final grades a partially raised system may be'

necessary. The raised system should be adequately covered with 2 feet of onsite materials and

topsoil, and all fill material slopes should not exceed a 3( H) : l(V) slope angle.

We recommend that the specifications outlined in Appendix B be followed. The soils engineershould be contacted to observe construction of the septic system and absorption field as well as

to verify that the soils encountered coincide with those that were tested.

MAINTENANCE

All septic systems must be maintained to operate properly. The homeowner shall take an active

role in maintaining their septic system. We have attached a copy of the National Small Flows

Clearing House publication entitled " Pipeline: Maintaining Your Septic System - A Guide For

Hom~owners." The homeowner should become familiar with the information contained within

this important document.

LIMITATIONS

This report has been prepared with generally accepted soil and foundation engineering practices

in this area for use by the client for design purposes. The conclusions and recommendations

presented in this report are based upon the data obtained from the exploratory holes excavated at

the locations indicated on the exploratory hole plan. !he nature and extent of variations between

the exploratory holes may not become evident until excavation is performed. If duringconstruction, soil, rock, and groundwater conditions appear to be different from those described

herein, this office should be advised at once so that reevaluation of therecommendations may be

made. We recommend on-site observations of excavations and foundation bearing strata by a

soil engineer.
