The scope of our services included the following: Observing the grading operation including the placement of compacted fill,the removal and/or processing of loose topsoil,alluvial deposits,landslide debris and undocumented fill placed by others; and the undercutting of formational material exposed at or near street subgrade to facilitate utility excavations. In addition, we observed the placement of several subdrain systems to verify proper installation. Performing in-place density and moisture content tests in fill placed and compacted on the pads/lots and associated streets. Performing laboratory tests to aid in evaluating the compaction, shear strength, and expansion characteristics of the soil material used as fill.In addition,the water-soluble sulfate content of randomly selected samples from finish grade was tested. Preparing an As-Graded Geologic Map. Preparing this final report of grading. The purpose of this report is to document that the grading of the subject business park has been performed in substantial conformance with the recommendations of the project geotechnical report and subsequent consultations and that the fill materials have been properly compacted. At the time of this report, the grading for Lots 1,2, and 6 was incomplete and an addendum report will be provided for these lots after completion. In addition, the density tests for portions of Lots 13 and 14 (Phase 2) that were part of the overall mass grading plan for Phase 1 have also been included herein. Grading operations for Phase 1 were performed concurrently with those for El Fuerte Street and Faraday Avenue. Geotechnical information relating to the grading of these roads is presented in the following reports: . Final Report of Testing and Observation Services During Roadway Grading, Carlsbad Oaks North Business Park. Faraday Avenue Extension - StationlO+OO through 80+80, Carlsbad, California, prepared by Geocon Incorporated, dated July 27, 2006 (Project Nos. 06442-32- 05A and 06442-32-06A). . Final Report of Testing and Observation Services During Site Grading, Carlsbad Oaks North Business Park, El Fuerte Street Extension - StationJO+OO through 38+00, Carlsbad, California, prepared by Geocon Incorporated, dated July 13, 2006 (Project No. 06442-32- 08A). An update geotechnical report presenting fine grading recommendations and geotechnical design criteria for the proposed ultimate development should be prepared by Geocon Incorporated once final plans have been prepared for the individual building pads. GENERAL The grading contractor for the project was Pinnick Incorporated of El Cajon, California. The project grading plans were prepared by O'Day Consultants, the project civil engineer, and are entitled Grading and Erosion Control Plans for: Carlsbad Oaks North, Phase 1, C. T. 97-]3, City of Carlsbad approval dated October 26, 2004 (Drawing No. 4l5-9A). Recommendations for grading were provided in our report entitled Update Geotechnical Investigation, Carlsbad Oaks North, Business Park and Faraday Avenue Offsite, Carlsbad, California, dated October 21,2004 (Project No. 06442- 32-03). Staking and collection of the field survey information was performed by O'Day Consultants. The exhibit used as a base map to present the as-graded geologic information and in-place density test locations (Figures 1 through 4) is a copy of a compilation of digital information provided by O'Day Consultants. The map depicts the ultimate grading configuration with respect to lot lines, slope areas, lot numbers, and finish pad elevations. In addition, the existing ground topography prior to grading is shown. The base-of-fill elevations are also presented. This information was collected by surveyors from O'Day Consultants during remedial grading operations. The as-graded geologic contacts were Project No. 06442-32-04A - 2- August 30, 2006 derived from intermittent field survey shots and estimates made by our field representatives based on survey and/or grade-checkers' stakes. In this regard, the contacts should be considered approximate. References to elevations and locations herein are based on as-graded survey information (remedial grading exhibits) provided by ü'Day Consultants or grade-checkers' stakes in the field. Geocon Incorporated does not provide surveying services and, therefore, has no opinion regarding the accuracy of the as-graded elevations or surface geometry with respect to the approved grading plans or proper surface drainage. GRADING Grading began with removing and exporting brush and vegetation from the areas to be graded. Topsoil, alluvium, landslide debris, and undocumented fill deposits were then removed to expose formational material. Within areas to receive fill, the exposed soil was then scarified, moisture conditioned and compacted. Fill materials from on-site excavations were then placed and compacted in layers until the design elevations were attained. The areas where hard rock or dense formational material was exposed at or near street subgrade were undercut approximately 7 feet to facilitate the excavations for underground utilities. The undercut criteria where formational materials exposed near finish grade of the building pads was determined on a case-by-case basis by the owner, depending upon the apparent rippability of the materials exposed. Future excavations in areas where undercuts were not performed may encounter difficult digging and require breaking and/or localized blasting. Also, oversize material may be generated by the excavations and require special handling. Refer to the "As-Graded" Geologic Map (Figures I through 4) for the approximate delineation of formational areas. Fill Materials and Placement Procedures The on-site fill materials generally consisted of silty to clayey sands and sandy clays with mixtures of gravel and boulders generated from the various formational units exposed on site. In general, the upper 10 feet of building pads and roadways were limited to oversize material less than 12 inches in maximum dimension and 6 inches in the upper 3 feet. Rock material greater than 12 inches was placed deeper than 10 feet below proposed finish grade and at least 3 feet below the deepest utility. Fill materials classified as "soil-rock" mixtures were placed in some portions of the site by spreading and compacting the materials with a Caterpillar bulldozer in lifts 2 to 3 feet thick or less. During placement of each lift, the fill was uniformly wheel-rolled with loaded rock trucks. These materials were heavily watered during spreading prior to compacting. Soil fills were placed in lifts no thicker than would allow for adequate bonding and compaction. The soil was moisture conditioned, as necessary, and mixed during placement. Project No. 06442-32-04A - 3 - August 30, 2006 Field In-Place Density and Laboratory Testing During grading, compaction procedures were observed and in-place density tests were performed to evaluate the relative compaction of the fill material. The in-place density tests were performed in general conformance with ASTM Test Method D 2922-01 (nuclear). Results of the field density tests and moisture content tests performed during grading are summarized on Table I and the approximate locations are presented on the "As-Graded" Geologic Map. In general, the in-place density test results indicate that the fill at the locations tested has a relative compaction of at least 90 percent and an appropriate moisture content. Laboratory tests were performed on samples of material used for fill to evaluate moisture-density relationships, optimum moisture content and maximum dry density (ASTM D 1557-02), expansion characteristics (ASTM D 4829-03), sulfate potential (CA Test No. 417) and shear strength (ASTM D 3080-03). Laboratory testing for Phase I (Lots 1 through 9) was performed concurrently with the grading for Faraday Avenue and EI Fuerte Street; as such, the sample numbers are not in consecutive order. The results of the laboratory tests that are applicable to the subject grading are summarized on Tables II through V. Slopes Cut and fill slopes were graded at design inclinations of 2: 1 (horizontal:vertical) or flatter, with maximum heights of approximately 70 feet. Slopes that exposed potentially adverse conditions (e.g., weak siltstones and claystones, erosive soils, extensive seepage, etc.) were provided with a stability fill. The area where a stability fill was constructed is shown on the "As-Graded" Geologic Map. In general, fill slopes were either over-filled and cut back or track-walked with a bulldozer during grading. Fill slopes comprised of clayier soil may be prone to surficial loosening due to cyclical wetting and drying and may require increased maintenance. All slopes should be planted, drained, and maintained to reduce erosion. Slope irrigation should be kept to a minimum to just support the vegetative cover. Surface drainage should not be allowed to flow over the top of the slope. Stabilization Fill Slopes A drained stabilization fill was constructed behind Lot 2 to reduce the potential of surficial slope instability due to the presence of weak claystone and siltstone materials and extensive seepage. In general, a 1: 1 (horizontal:vertical) backcut was initiated beyond the top of slope and was extended below pad grade. A heel drain and panel drain system was installed to collect the seepage encountered along the temporary backcut. The excavation was then was backfilled with compacted granular fill material. Figure 5, Geologic Cross Section A-A', shows the approximate limits of the stability fill. Project No. 06442-32-04A - 4- August 30, 2006 Subdrains (General) Two types of subdrains were constructed in accordance with our recommendations. The systems consisted of a stability fill backdrain and canyon subdrains. The subdrain locations were surveyed by the project civil engineer and the locations are presented on the "As-Graded" Geologic Map. Additional discussion regarding the construction of the drainage systems is provided below. The final segment of subdrains consisted of non-perforated drainage pipe provided with a concrete cut-off wall constructed at the perforated/non-perforated interface. It is recommended that all subdrain outlets that empty into open space or brow ditches be provided with a headwall structure to protect the end of the pipe from damage or burial. Stability Fill Backdrains The stability fill constructed on the north facing slope behind Lot 2 was provided with a drain system consisting of 4-foot-wide Mirafi drainage panels positioned approximately 20 to 30 feet on center and vertically oriented against the temporary backcut and connected to a heel drain at the bottom. The heel drain consisted of an 8-inch-diameter perforated PVC pipe surrounded by %-inch, open-graded gravel wrapped in filter fabric. The heel drain was extended to the west and east along the stability fill backcut and ultimately connected to a storm drain box structure located outside of the toe of slope at El Fuerte Street approximate Station 17+75 and into the brow ditch situated on the west side of Lot 2. In addition, heel drain cleanouts were installed along the stability fill backcut in the event that future maintenance is necessary. The cleanouts were capped at the finish ground surface and their locations have been shown on the "As-Graded" Geologic Map. Canyon Subdrains Typical canyon subdrains consisting of 8-inch, perforated PVC pipe encapsulated in gravel and filter fabric were placed at the base of the remedial excavations where a depression occurred in the bedrock topography. Some of the original subdrain alignments were later diverted due to conflicts with underground utilities in Faraday A venue which were not known during the initial placement of the subdrain system. Finish Grade Soil Conditions Observations and laboratory test results indicate that prevailing soils randomly sampled (for Lots 3, 4, 5, 7 and 8) at finish grade have an Expansion Index (EI) ranging from 0 to 2 and are classified as having a "very low" expansion potential (El of 20 or less) as defined by Uniform Building Code (UBC) Table 18-I-B. The expansion condition for the lots in an interim condition will be provided upon completion of grading. Table III presents the results of the expansion classification for the prevailing soils at finish grade. Project No. 06442-32-04A - 5 - August 30, 2006 Oversize fragments and rock materials were generated from excavations during the grading operation. To the extent possible, the oversize material was placed within the "hold down" areas as previously discussed. The potential for encountering oversize materials (12 inches or greater) should be considered if deep excavations (10 feet or more) are proposed (i.e., underground utilities, etc.). Although particular attention was given to restricting the oversize material to the placement zones described previously, some randomly occurring fragments larger than 12 inches in nominal diameter may be present in the upper portions of fill areas. The performance of the fill, however, should not be adversely affected and the grading performed is considered to be in substantial conformance with our recommendations. Corrosion Laboratory tests performed on random soil samples to measure the percentage of water-soluble sulfate of the compacted fill at finish grade for Lots 3 through 5, and 7 and 8 indicate that the on-site materials possess a "negligible" to "moderate" potential for sulfate exposure to concrete structures, as defined by UBC Table 19-A-4. Table V presents the results of the water-soluble sulfate for the various lots sampled (Lots 3, 4, 5, 7, and 8). Geocon Incorporated does not practice m the field of corrosion engineering. Therefore, it is recommended that further evaluation by a corrosion engineer be performed if improvements are planned that are susceptible to corrosion. SOIL AND GEOLOGIC CONDITIONS In general, the soil and geologic conditions encountered during grading were found to be similar to those described in the referenced project geotechnical report. The enclosed "As-Graded" Geologic Map (Figures 1 through 4) depicts the general geologic conditions observed. Information provided by the project paleontologist was utilized in identifying the geologic units. Figure 5 (Geologic Cross Section A-A') represents the general geometry of the stability fill. The figures have been annotated to show a general representation of the as-graded geologic conditions observed during grading. Geologic contacts should be considered approximate. No geologic conditions were observed during grading that would preclude the continued development of the lots. CONCLUSIONS AND RECOMMENDATIONS 1.0 General 1.1 Based on observations and test results, it is the opinion of Geocon Incorporated that the grading, which is the subject of this report, has been performed in substantial conformance with the recommendations of the referenced project soil reports. Soil and geologic conditions encountered during grading that differ from those anticipated by the project soil Project No. 06442-32-04A - 6- August 30, 2006 report are not uncommon. Where such conditions required a significant modification to the recommendations of the project soil report, they have been described herein. 1.2 No soil or geologic conditions were observed during grading that would preclude the continued development of the property as planned. Based upon laboratory test results and field observations, it is our opinion that the fill soils within the subject lots and associated streets have generally been compacted to at least 90 percent relative compaction at the locations tested. 1.3 Fine grading and construction of utilities/foundations may encounter non-rippable formational material and/or generate some concretionary fragments and/or rock material 12 inches or greater in situ. Deeper excavations within the fill (10 feet or greater) for improvements such as utility lines, loading docks, etc., may also encounter oversize material (12 inches or greater). The potential for these conditions should be taken into consideration when determining the type of equipment to utilize for future excavation operations. The oversize material may require special handling techniques and exportation. 1.4 It is not uncommon for groundwater or seepage conditions to develop where none previously existed, particularly after landscape irrigation is initiated. The occurrence of induced groundwater seepage from landscaping can be greatly reduced by implementing and monitoring a landscape program that limits irrigation to that sufficient to support the vegetative cover without overwatering. Shallow subdrains may be required in the future if seeps occur after rainy periods or after landscaping is installed. 1.5 References to the thickness and extent of rock hold-down areas within roadways or capping of building pads are approximate and were based upon the finish grade elevations of the approved referenced grading plans. 2.0 Drainage 2.1 Adequate drainage provisions are imperative. Under no circumstances should water be allowed to pond adjacent to footings. The building pads should be properly finish graded after the buildings and other improvements are in place so that drainage water is directed away from foundations, pavements, concrete slabs, and slope tops to controlled drainage devices. Project No. 06442-32-04A - 7 - August 30, 2006 3.0 Update Geotechnical Report 3.1 An update geotechnical report presenting fine-grading recommendations and geotechnical design criteria should be prepared by Geocon Incorporated once the final development plans have been prepared for the subject lots. LIMITATIONS The conclusions and recommendations contained herein apply only to our work with respect to grading and represent conditions at the date of our final observation of grading operations on June 13, 2006. Any subsequent grading should be done in conjunction with our observation and testing serVices. As used herein, the term "observation" implies only that we observed the progress of the work with which we agreed to be involved. Our services did not include the evaluation or identification of the potential presence of hazardous materials. Our conclusions and opinions as to whether the work essentially complies with the job specifications are based on our observations, experience and test results. Due to the inaccuracies inherent in most field and laboratory soil tests, and the necessary assumption that the relatively small soil sample tested is representative of a significantly larger volume of soil, future tests of the same soil location or condition should not be expected to duplicate specific individual test results of this report. Subsurface conditions, and the accuracy of tests used to measure such conditions, can vary greatly at any time. We make no warranty, express or implied, except that our services were performed in accordance with engineering principles generally accepted at this time and location. We will accept no responsibility for any subsequent changes made to the site by others, by the uncontrolled action of water, or by the failure of others to properly repair damages caused by the uncontrolled action of water. It is the responsibility of Techbilt Construction Company to ensure that the information and recommendations contained herein are brought to the attention of the architect and engineer for the project, are incorporated into the plans, and that the necessary steps are taken to see that the contractor and subcontractors carry out such recommendations in the field. Recommendations that pertain to the future maintenance and care for the property should be brought to the attention of future owners of the property or portions thereof. The findings and recommendations of this report may be invalidated wholly or partially by changes outside our control. Therefore, this report is subject to review and should not be relied upon after a period of three years.
