W.O. 791-SD OCTOBER 27, 1987 PAGE 2 SITE DESCRIPTION The subject property is an approximately 0.24 acre parcel located on the north side of Tamarack Avenue between Garfield Street and Carlsbad Boulevard in the City of Carlsbad, California. The site is rectangular in shape and slopes gently to the southwest at gradients, of 10:1 or less. Maximum relief across the site approximately is 8 feet. Drainage is by sheet flow to Tamarack Avenue. I No structures exist on the site, and no evidence of previous site development was observed. Wood and other debris has been dumped adjacent to the northern property limits. Vegetation onsite is I limited to sparse, low growing weeds. Adjoining parcels to the west, *north, and east are occupied by single family apartment residential structures. A retaining wall approximately three feet high exists along the northern portion of the east property line. I SITE DEVELOPMENT Undated plans for the site, provided by Mr. Dennis Stewart, I indicate that two story wood frame condominiums are to be I I GeoSoUs, PRELIMINARY GEOTECHNICAL STUDY LOTS 9 AND 10, BLOCK G, PALISADES TRACT CITY OF CARLSBAD, COUNTY OF SAN DIEGO, STATE OF CALIFORNIA, NAP NO.' 1747 FOR ALIMIGA INVESTMENTS INCORPORATED C/O MR.

OCTOBER 27, 1987 W.O. 791-SD PAGE 3 I I constructed. It is anticipated that approximately the existing grades are to be utilized. I EARTH MATERIALS I The site is blanketed by terrace deposits consisting of medium brown, moist, very loose, porous sand. The upper 1 t 1.5 feet includes minor organics and a slightly higher silt content, indicating early stages of topsoil development. The terrace deposit sands become slightly moist to dry at depths ranging from I l to 2 feet, and become medium dense to dense at depths ranging from 3 to 4 feet. The upper loose, porous zone of the terrace. deposits is considered unsuitable for structural support. This material is suitable for use as compacted fill provided it is cleaned of deleterious debris. GROUNDWATER Groundwater was not encountered in our test trenches and there is no evidence of near-surface groundwater on or in the immediate vicinity of the site. However, a southwesterly trending drain consisting of a four inch -diameter vitrified clay pipe embedded in gravel was encountered in Test Pit TP-l. The extent of this I GeooUs, I I ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 4 I I drain should be evaluated during site grading. Recommendations concerning treatment of the drain may be provided at that time. I SEISMICITY I The site, as all of Southern California, is in a seismically active region. Although there are no known active or potentially I active faults on or in the immediate proximity of the site, there are faults in close enough proximity to cause earthquake-induced I ground shaking on the site. Moderate to intense ground shaking I should be anticipated within the next 50 to 100 years. Seismically resistant structural design is recommended. I FIELD EXPLORATION I I Subsurface conditions were explored by excavating five exploratory trenches utilizing a tractor mounted backhoe with 24- inch digging bucket. Trench locations are indicated on the Site Exploration Map, Plate 1, which is based on a conceptual plan I provided by Mr. Stewart. The trenches range from 4.5 to 5.5 feet I in depth. Logs of the trenches are included in this report as Table I. Field exploration was performed on October 16, 1987. I I I GeoSoUs, Inc. I I ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD - PAGE 5 I LABORATORY TESTING I Compaction Tests To determine the compaction character of site soils, compaction I testing was performed on a representative sample of near surface I terrace deposit material. Testing was performed in accordance with ASTM Test D-1557-78. A laboratory maximum dry density of I 124.0 pounds per cubic foot and an optimum moisture content of 10.0 percent was determined for this soil. I Expansion Tests A swell test was performed on a remolded sample of the I Terrace deposit material. The sample was prepared at 80 percent of the optimum moisture, and at 90 percent of the I maximum dry density. Thesample was placed under a 60-pound per square foot surcharge and submerged in water for 24 I hours. The percent swell was then recorded as the amount of vertical rise compared to the original -one-inch sample I height. A swell of less than one percent, which is I considered low expansive, was recorded for this soil. An expansion index test was also performed with a sample of the same material. Testing was performed in accordance with I Standard 29-2 of the Uniform Building Code. The test result I I GeoSofls, Inc. ALMIGA INVESTMENTS, INC. - OCTOBER 27, 1987 W.O. 791-SD - PAGE 6 was an expansion index of 2, which is classified as very low according to Table 29-C of the Uniforms Building Code. I CONCLUSIONS AND RECOMMENDATIONS Based upon the geotechnical data presented herein, it is our opinion that the subject property is suited for the proposed development from a soil engineering and geologic viewpoint, provided that the recommendations presented below are incorporated into the final design, grading, and construction phases of development. Treatment of Existing Ground and Fill Placement 1. Debris, vegetation, and other deleterious materials should be removed from the site. I 2. The upper, loose zone of the terrace deposits should be removed within each building pad area and three feet beyond I in each direction. Removals should extend to a depth of three feet below the existing elevations or three feet below I pad grade, which ever is lower. I Care should be taken during grading not to undermine existing improvements on adjacent properties (e.g. minor I retaining walls). Evaluation of associated conditions should I I GeoSoUs, Inc. I I I I I I LI I I I I I I AL14IGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 7 I be made at the start of grading. Appropriate measures to mitigate any damage should be taken. All removal areas should be observed by a representative of I this office to evaluate if adequate removal depths have been I obtained. When removals are completed, the exposed surface should be I scarified to a depth of 12 inches, brought to at least optimum moisture content and compacted. I Subsequent to ground preparation, the excavated onsite soils may be placed in thin (6± inch) lifts, cleansed of vegetation and debris, brought to at least optimum moisture I content, and compacted to a minimum relative compaction of I 90 percent of laboratory standard as determined by ASTM test D-15577-78. If soil is to be imported to the site for use as compacted I fill, it should be evaluated by this office prior to importing it to the site. If import soil is expansive, I increased foundation design should be anticipated. I 5. Grading should be performed in accordance with the requirements of the City of Carlsbad, and to the minimum I standards of Chapter 70 of the Uniform Building Code, and the Grading Guidelines .enclosed herein as Appendix I. I GeoSoUs, Inc. I I AIMIGA INVESTMENTS, INC. W.O. 791-SD I OCTOBER 27, 1987 PAGE 8 I FOUNDATION DESIGN An allowable soil bearing pressure of 1,500 pounds per square foot may be used for the design of footings founded I in compacted fill and constructed in accordance with minimum I requirements of the Uniform Building Code regarding width and depth. The bearing value may be increased by one-third I for seismic or other temporary loads. The active earth pressure to be utilized for cantilevered retaining wall design may be computed as an equivalent fluid I having a density of 30 pounds per cubic foot where the backfill behind the wall is level. I 3. An allowable coefficient of friction between concrete and I compacted fill of 0.4 may be used with the deadload. forces. FOUNDATION CONSTRUCTION I Onsite soils are considered to be low expansive in nature. The I following recommendations would be applicable if testing at the completion of grading indicates low expansive soils. 1. Footings may be constructed according to standard building I code requirements regarding width and depth. I GeoSofls, Inc. I I . I I I I I I I I I I . I I I I I I I ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 9 All footings should be reinforced with a minimum of two No. 4 steel reinforcing bars, one placed near the top and one placed near the bottom of the footing. Where moisture condensation is undesirable, concrete slabs should be underlain with a moisture barrier consisting of a minimum of 6-mil polyvinyl chloride or equivalent membrane, with all laps sealed. This membrane should be covered with a minimum of one-inch of sand to aid in uniform curing of the concrete. Concrete slabs should be reinforced with a minimum of 6 inch by 6 inch, No. 10 by No. 10 welded wire mesh to control cracking due to contraction. Slab reinforcement should be supported to ensure placement near the vertical midpoint of the slab. Although no specific presaturation is required for these soil conditions, footing trench excavations and slab area soils should be well watered prior to pouring concrete. UTILITY TRENCH BACKFILL Utility trench backfill should be placed in the following standards: GeoSo Us, Inc. I I ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 10 I I 1. Ninety percent of the laboratory standard if native material is used as backfill. 2. As an alternative, clean sand may be utilized and flooded or I jetted into place with no specific relative compaction required. Observation, probing, and if deemed necessary, I testing may be required to verify adequate results. I 3. Exterior trenches paralleling a footing and extending below a 1:1 plane projected from the outside bottom edge of I footing should be compacted to 90 percent of the laboratory I standard. Sand backfill, unless it is similar -to the inplace fill, should be not allowed in these trench backfill areas. Density testing, along with probing, should be accomplished to verify the desired results. I I REVIEW I Detailed site development, grading and foundation plans should be reviewed by this office prior to the start of site grading. I Additional or modified recommendations may be offered at that i time. 11 I I GeeSe Us, Inc. 1142 Principal Engineer I. I . I I I I I I I I . I I I I I I ALMIGA INVESTMENTS, INC.

I GRADING GUIDELINES I I I I I I I I I I GeoSoUs, Inc. GRADING GUIDELINES Grading should be performed to at least the minimum requirements I of the governing agencies, Chapter 70 of the Uniform Building Code and the guidelines presented below: Treatment of Existing Ground I 1. All heavy vegetation, rubbish and other deleterious materials should be disposed of off site. I 2. All loose surficial deposits should be removed as I described in the body of this report. Deeper removals than indicated in the text of the report may be I necessary due to saturation during winter months. 1 3. Subsequent to removals, the natural ground should be I scarified to a-depth of twelve inches, moistened to at least optimum moisture content and compacted to fill standards. I Fill Placement All site soil may be reused for compacted fill; I however, some special processing or handling may be required (see report). I Material used in the compacting, process should be I evenly spread, moisture conditioned, processed, and compacted in thin lifts not to exceed six inches in I thickness to obtain a uniformly dense layer. The fill I I GeoSofls, Inc. I I ALMIGA INVESTMENTS INCORPORATED OCTOBER 27, 1987 W.O. 791-SD GRADING GUIDELINES PAGE 2 I I . should be placed and compacted on a horizontal plane, unless otherwise found acceptable by the Soil Engineer. If the moisture content or relative density varies from I that acceptable to the Soil Engineer, the Contractor should rework the fill until it is in accordance with the following: a) Moisture content of the fill should be above optimum I . moisture. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or I removal areas should be considered in addition to watering during fill placement particularly in clay or I dry surficial soils. I b) Each six inch layer should be compacted to at least 90 percent of the maximum density in compliance with the I testing method specified by the controlling I governmental agency. In this case, the testing method is ASTN test D-1557-78. Rocks or concrete fragments less than eight inches in I diameter may be utilized in the fill, provided: I GeoSof is, Inc. I ALMIGA INVESTMENTS INCORPORATED OCTOBER 27, 1987 W.O. 791-SD GRADING GUIDELINES PAGE 3 I I : They are not placed in concentrated pockets'; There is a sufficient percentage of fine-grained I material to surround the rocks; C. The distribution of the rocks is supervised by the Soil Engineer. I 5. Rocks or concrete fragments greater than eight inches in diameter should be taken off site. I 6. Transition lots (cut and fill) should be capped with a three I foot thick compacted fill blanket. I 7. Exploratory backhoe trenches still remaining after site removal should be excavated and filled with compacted I fill if they can be located. Grading Observation and Testing I 1. Observation of the fill placement should be provided by the Soil Engineer during the progress of grading. 2. In general, density tests would be made at intervals not I exceeding two feet of fill height or every 1,000 cubic yards of fill placed. This criteria will vary depending I on soil conditions and the size of the fill. In any event, an adequate number of field density tests should I GeoSofls, Inc. H I ALMIGA INVESTMENTS INCORPORATED OCTOBER 27, 1987 W.O. 791-SD - GRADING GUIDELINES PAGE 4 I I be made to evaluate if the required compaction and moisture content is generally being obtained. Density tests may be made on the surface material to receive fill, as required by the Soil Engineer. Cleanouts and processed ground to receive fill should be observed by the Soil Engineer prior to placing any fill. It will be the Contractor's responsibility to notify the Soil Engineer when such areas are ready for observation. Utility Trench Backfill Utility trench backfill should be placed to the following standards: Ninety percent of the laboratory standard if native material is used as backfill. As an alternative, clean sand may be utilized and flooded into place. No specific relative compaction would be required; however, observation, probing, and if deemed necessary, testing may be required. Exterior trenches, paralleling a footing and extending below a 1:1 plane projected from the outside bottom edge of the footing, should be compacted to 90 percent of the GeoSofls, Inc. ALMIGA INVESTMENTS INCORPORATED OCTOBER 27, 1987 W.O. 791-SD GRADING GUIDELINES PAGE 5 laboratory standard. Sand backfill, until it is similar to the inplace fill, should not be allowed in these trench backfill areas. Density testing along with probing should be accomplished to verify the desired results.

The purpose of our study was to evaluate the geotechnical conditions on the site with respect to the proposed development. Our study consisted of the following: Review of pertinent geotechnical literature. Excavating, logging, and sampling of five exploratory backhoe trenches. Laboratory analysis of samples obtained. Appropriate geologic and soil engineering analysis. This report presents our findings, conclusions, and recommendations for site development. Los Angeles County Office: (818) 785-2158 . Orange County Office: (714) 647-0277 I I ALMIGA INVESTMENTS, INC. W.O. 791-SD OCTOBER 27, 1987 PAGE 2 I SITE DESCRIPTION The subject property is an approximately 0.24 acre parcel located on the north side of Tamarack Avenue between Garfield Street and Carlsbad Boulevard in the City of Carlsbad, California. The site is rectangular in shape and slopes gently to the southwest at gradients, of 10:1 or less. Maximum relief across the site approximately is 8 feet. Drainage is by sheet flow to Tamarack Avenue. I No structures exist on the site, and no evidence of previous site development was observed. Wood and other debris has been dumped I adjacent to the northern property limits. Vegetation onsite is limited to sparse, low growing weeds. I Adjoining parcels to the west, north, and east are occupied by I single family apartment residential structures. A retaining wall approximately three feet high exists along the northern portion I of the east property line. I SITE DEVELOPMENT Undated plans for the site, provided by Mr. Dennis Stewart, I indicate that, two story 'wood frame condominiums are to be I I GeoSofls, Inc. I I I I n I I ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 3 I . I constructed. It is anticipated that approximately the existing grades are to be utilized. I EARTH MATERIALS I I The site is blanketed by terrace deposits consisting of medium brown, moist, very loose, porous sand. The upper 1 -to 1.5 feet includes minor organics and a slightly higher silt content, indicating early stages of topsoil development. The terrace I deposit sands become slightly moist to dry at depths ranging from I l to 2 feet, and become medium dense to dense at depths ranging from 3 to 4 feet. The upper loose, porous zone of the terrace. deposits is I considered unsuitable for structural support. This material is suitable for use as compacted fill provided it is cleaned of I deleterious debris. I Groundwater was not encountered in our test trenches and there is no evidence of near-surface groundwater on or in the immediate vicinity of the site. However, a southwesterly trending drain consisting of a four inch diameter vitrified clay pipe embedded in gravel was encountered in Test Pit TP-1. The extent of this I Gez,SoUs, Inc. ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD - PAGE 4 drain should be evaluated during site grading. Recommendations concerning treatment of the drain may be provided at that time. SEISMICITY I The site, as all of Southern California, is in a seismically active region. Although there are no known active or potentially active faults on or in the immediate proximity of the site, there are faults in close enough proximity to cause earthquake- induced- I ground shaking on the site. Moderate to intense ground shaking, I should be anticipated within the next 50 to 100 years. Seismically resistant structural design is recommended. I FIELD EXPLORATION Subsurface conditions were explored by excavating five exploratory trenches utilizing a tractor mounted bac]thoe with 24- inch digging bucket. Trench locations are indicated on the Site Exploration Map, Plate 1, which is based on a conceptual plan provided by Mr. Stewart. The trenches range from 4.5 to 5.5 feet in depth. Logs of the trenches are included in this report as Table I. Field exploration was performed on October 16, 1987. GeoSofls, Inc. I I ALMIGA INVESTMENTS, INC. W.O. 791-SD OCTOBER 27, 1987 PAGE 5 I LABORATORY TESTING Compaction Tests To determine the compaction character of site soils, compaction testing was performed on a representative sample of near surface terrace deposit material. Testing was performed in accordance with ASTM Test D-1557-78. A laboratory maximum dry density of 124.0 pounds per cubic foot and an optimum moisture content of 10.0 percent was determined for this soil. Expansion Tests A swell test was performed on a remolded sample of the Terrace deposit material. The sample was prepared at 80 percent of the optimum moisture, and at 90 percent of the maximum dry density. The sample was placed under a 60-pound per square foot surcharge and submerged in water for 24 hours. The percent swell was then recorded as the amount of vertical rise compared to the original one-inch sample height. A swell of less than one percent, which is considered low expansive, was recorded for this soil. An expansion index test was also performed with a sample of the same material. Testing was performed in accordance with Standard 29-2 of the Uniform Building Code. The test result GeoSofls, Inc. I I I I I LI I I I I 17 I I I I I I I ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 6 I I was an expansion index of 2, which is classified as very low according to Table 29-C of the Uniform. Building Code. I CONCLUSIONS AND RECOMMENDATIONS I I Based upon the geotechnical data presented herein, it is our opinion that the subject property is suited for the proposed I development from a soil engineering and geologic viewpoint, provided that the recommendations presented below are .1 incorporated into the final design, grading, and construction phases of development. Treatment of Existing Ground and Fill Placement I 1. Debris, vegetation, and other deleterious materials should be removed from the site. I 2. The upper, loose zone of the terrace deposits should be removed within each building pad area and three feet beyond I in each direction. Removals should extend to a depth of three feet below the existing elevations or three feet below pad grade, which ever is lower. I Care should be taken during grading not to undermine existing improvements on adjacent properties (e.g. minor I retaining walls). Evaluation of associated conditions should I I GeoSofls, I I ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 7 I I be made at the start of grading. Appropriate measures to mitigate any damage should be taken. All removal areas should be observed by a representative of I this office to evaluate if adequate removal depths have been obtained. When removals are completed, the exposed surface should be I scarified to a depth of 12 inches, brought to at least optimum moisture content and compacted. I Subsequent to ground preparation, the excavated onsite soils may be placed in thin (6± inch) lifts, cleansed of vegetation and debris, brought to at least optimum moisture I content, and compacted to a minimum relative compaction of I 90 percent of laboratory standard as determined by ASTM test D-15577-78. If soil is to be imported to the site for use as compacted I fill, it should be evaluated by this office prior to importing it to the site. If import soil is expansive, I increased foundation design should be anticipated. I 5. Grading should be performed in accordance with the requirements of the City of Carlsbad, and to the minimum I standards of Chapter 70 of the Uniform Building Code, and the Grading Guidelines enclosed herein as Appendix I. GeoSoUs, Inc. j I ALMIGA INVESTMENTS, INC. W.O. 791-SD OCTOBER 27, 1987 PAGE 8 I I FOUNDATION DESIGN An allowable soil bearing pressure of 1,500 pounds per square foot may be used for the design of footings founded I in compacted fill and constructed in accordance with minimum I requirements of the Uniform Building Code regarding width and depth. The bearing value may be increased by one-third I for seismic or other temporary loads. The active earth pressure to be utilized for cantilevered retaining wall design may be computed as an equivalent fluid I having a density of 30 pounds per cubic foot where the backfill behind the wall is level. I 3. An allowable coefficient of friction between concrete and I compacted fill of 0.4 may be used with the deadload forces. FOUNDATION CONSTRUCTION I Onsite soils are considered to be low expansive in nature. The I following recommendations would be applicable if testing at the completion of grading indicates low expansive soils. 1. Footings may be constructed according to standard building I code requirements regarding width and depth. I GeoSefls, Inc. ALMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 9 All footings should be reinforced with a minimum of two No. 4 steel reinforcing bars, one placed near the top and one placed near the bottom of the footing. Where moisture condensation is undesirable, concrete slabs should be underlain with a moisture barrier consisting of a minimum of 6-mil polyvinyl chloride or equivalent membrane, with all laps sealed. This membrane should be covered with a minimum of one-inch of sand to aid in uniform curing of the concrete. Concrete slabs should be reinforced with a minimum of 6 inch by 6 inch, No. 10 by No. 10 welded wire mesh to control cracking due to contraction. Slab reinforcement should be supported to ensure placement near the vertical midpoint of the slab. Although no specific presaturation is required for these soil conditions, footing trench excavations and slab area soils should be well watered prior to pouring concrete. UTILITY TRENCH BACKFILL Utility trench backfill should be placed in the following standards: GeoSofls, Zvc. AIMIGA INVESTMENTS, INC. OCTOBER 27, 1987 W.O. 791-SD PAGE 10 Ninety percent of the laboratory standard if native material is used as backfill. As an alternative, clean sand may be utilized and flooded or jetted into place with no specific relative compaction required. Observation, probing, and if deemed necessary, testing may be required to verify adequate results. 3. Exterior trenches paralleling a footing and extending below a 1:1 plane projected from the outside bottom edge of' footing should be compacted to 90 percent of the laboratory standard. Sand backfill, unless it is similar to the inplace fill, should be not allowed in these trench backfill areas. Density testing, along with probing, should be accomplished to verify the desired results. I REVIEW Detailed site development, grading and foundation plans should be reviewed by this office prior to the start of site grading. Additional or modified recommendations may be offered at that time. I I GeoSoUs, Inc. I I I I I I I I I I I I I I I 1142 Principal Engineer I I I I I I I I I I .

I GRADING GUIDELINES GeOSOUS, Inc. LI I GRADING GUIDELINES Grading should be performed to at least the minimum requirements of the governing agencies, Chapter 70 of the Uniform Building Code and the guidelines presented below: Treatment of Existing Ground I 1. All heavy vegetation, rubbish and other deleterious should be disposed of off site. I materials 2. - All . loose surf icial deposits should be removed as I described in the body of this report. Deeper removals than indicated in the •text of the report may be I necessary due to saturation during winter months. I 3. Subsequent to removals, the natural ground should be I scarified to a-depth of twelve inches, moistened to at least optimum moisture content and compacted to fill standards. I Fill Placement 1. All site soil may be reused for compacted fill; however, some special processing or handling may be required (see report). 2. Material used in the compacting, process should be I evenly spread, moisture conditioned, processed, and compacted in thin lifts not to exceed six inches in I thickness to obtain a uniformly dense layer. The fill I I . GeoSos, Inc. I I ALMIGA INVESTMENTS INCORPORATED OCTOBER 27, 1987 W.O. 791-SD GRADING GUIDELINES PAGE 2 I I . should be placed and compacted. on a horizontal plane, unless otherwise found acceptable by the Soil Engineer. If the moisture content or relative density varies from I that acceptable to the Soil Engineer, the Contractor - should rework the fill until it is in accordance with the following: a) Moisture content of the fill should be above optimum I moisture. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or I removal areas should be considered in addition to watering during fill placement particularly in clay or I dry surficial soils. I b) Each six inch layer should be compacted to at least 90 percent of the maximum density in compliance with the I testing method specified by the controlling I governmental agency. In this case, the testing method is ASTN test D-1557-78. Rocks or concrete fragments less than eight inches in diameter may be utilized in the fill, provided: I . I GeaSoUs, LI I ALMIGA INVESTMENTS INCORPORATED OCTOBER 27, 1987 W.O. 791-SD GRADING GUIDELINES PAGE 3 I I a. They are not placed in concentrated pockets; b. There is a sufficient percentage of fine-grained I material to surround the rocks; C. The distribution of the rocks is supervised by the Soil Engineer. I 5. Rocks or concrete fragments greater than eight inches in diameter should be taken off site. I Transition lots (cut and fill) should be capped with a three foot thick compacted fill blanket. Exploratory backhoe trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. Grading Observation and Testing Observation of the fill placement should be provided by the Soil Engineer during the progress of grading. In general, density tests would be made at intervals not exceeding two feet of fill height or every 1,000 cubic yards of fill placed. This criteria will vary depending on soil conditions and the size of the fill. In any event, an adequate number of field density tests should GeoSofls, Inc.
