"Amended Conformance Letter For Grading Conducted on Lots #4, #5, #6, and #7, Palomar Forum, City of Carlsbad Project #99-06, Drawing #399-4A", prepared by this office, dated November 19, 2004, Job #04-315-F. II. GEOLOGY Geologic conditions at the project site were exposed in graded excavations including cut slopes along the south perimeter below Palomar Airport Road. The slopes expose a section of sedimentary formational rocks including fine-grained sandstone with siltstone and claystone interbeds. Structural conditions are dominated by poorly developed bedding surfaces that are flat-lying or dip in a southerly direction at low angles. These conditions are favorable for the gross geologic stability of the cut slopes. The noted section is impacted by a related series of shears exposed in the slope above Lot #5 (See Sheet 6 of 7). The shears are steeply dipping breaks that evidence minor off- set of the _Eocene aged rocks. The shear zone is not related to a significant or potentially active fault and will not affect the development of Lot #5. Ill. G'RADING INFORMATION/GROUND PREPARATION Prior to grading operations, the site within the limits-shown on the approved grading plan was cleared of. vegetation. All questionable loose and compres~ible soils were also removed from the areas receiving fill. Adequate keys or benches were constructed a minimum of 2-feet into firm, undisturbed natural ground or formational soils prior to fill placemer:it. As of this date the cut portion of lots #4, and #5 have not been undercut a minimum of 3- feet or ~2-inches below the bottom of the deepest footing, and replaced as a structural fill which will decrease the potential for concrete cracking along the daylight (cut/fill) line. It is understood that this will be completed when the location and layout of the proposed buildings and improvements for each lot is known, and "fine grading" is conducted on these lots. Lots #6 and #7 are all "fill" lots, therefore mitigation for cut/fill lines is not warranted. A canyon subdrain was installed in accordance with the recommendations put forth in our above referenced "Geotechnical Update and Grading Plan Review'' r~port. The locations are shown on Sheet 7 of ?attached herein. Vertical clean-out sites were eliminated from the extendetj pipes by increasing the recommended pipe diameters by 2-inches. The completed system was camera videoed after filling began.

The rocks were placed in "windrows" with 20-foot separation between each windrow. The rocks were kept a minimum .of 15-feet from the face of slope with a minimum of 10-feet of compacted fill above the rocks. 6-inch minus asphalt was buried beneath Eagle Drive approximately 15-feet below finish surface of the roadway between station 18+40 and 21+00. • Stabilization fill'ing was conducted in the graded embankment along the south perimeter of the project above Lots #3 and #5. The work was necessary to repair erosions associated withAhe recent record high winter rains. Above Lot #3, .deep gullies were created by uncontrolled run-off from Palomar Airport Road above. The stabilization fill above Lot #5 was to repair a slope failure within saturated claystone units which were also impacted by uncontrolled run-off, see Plate A-A Details of the slide condition and repair recommendations were given in the referenced "Slope Repair'' letter prepared by this office, dated November, 2004. The repair was completed in substantial conformance with the repair recommendations. Site preparation and grading were conducted in substantial conformance with Appendix Chapter 33 of the 2001 Uniform Building Code, the Grading Ordinance for the City of Carlsbad and our above listed geotechnical update report. All inspections and testing were conducted under the observation of this office. In our"opinion, all embankments and excavations were constructed in substantial conformance· with the provided grading plan, and are acceptable in that these lots are "contour" graded. IV. FILL PLACEMENT Fill was placed in 6 to 8-inch lifts and compacted by means of heavy construction equipment. Field density tests were performed in accordance with ASTM Method D-1556 sand cone method and ASTM D-2922 nuclear densimeter as the fills were placed. The moisture content for each density sample was also determined. The approximate locations of the field density tests are shown on the attached plans. The locations of the tests were placed to provide the best possible coverage. Areas of low compaction, as indicated by the field density tests, were brought to the attention of the contractor. These areas were reworked by the contractor and retested. The test locations and final test results are summarized on the compaction test result table. Elevations and locations of field density tests were determined by hand level and pacing/tape measure relative to field staking done by others.

A. Lot #3: The bottom 32-feet was compacted to a minimum of 93% compacted fill, overlaid by a 23-foot secti.on of 90% compacted fill. Overall fill differential depth is approximately 50-feet. B. Lots #4 and #5: Both are underlaid by 90% compacted fills, with approximate fill differential depth of 15-feet. C. Lot #6: Is underlaid by 90% compacted fills, with approximate fill differential depth of 5-feet. D. Canyon Areas, Lot #7: The bottom 11-feet was compacted to a minimum 95%, overlaid with a 35-foot section of 93% compacted fill, overlaid by a 20-foot section of 90% compacted fill. Overall fill differential depth is approximately 50-feet. V. APPROPRIATE LABORATORY TESTS A. Maximum Dry Density Optimum Moisture Tests: The maximum dry density and optimum moisture contents of the different soil types used as compacted fifl were· determined in accordance with ASTM Method D-1557. B. Expansion Tests: . Expansion tests were conducted per 2001 UBC Standard Procedure 18-2 on representative samples of the on site clayey soils during the preliminary investigative phase_ of the project in order to determine the expansion potential and to provide appropriate foundation recommendations. As no new soils were encountered during the grading operations, no additional testing was conducted. The clayey soils placed on these lots range from medium to high expansive, Expansion Index ranging from a low of 51 to a high of 130. C. Direct She_ar Tests: Direct shear tests were conducted on representative samples of the on site soils during the preliminary investigative phase of the project in order to determine the allowable bearing capacity and to provide retaining wall design parameters. As no new soils were encountered during the grading operations, no additional testing was conducted. Appropriate laboratory testing will be conducted after the completion of "fine grading", in order to provide site specific recommendations.

REC.OMMENDATIONS A. Foundations Page5 February 16, 2005 Foundation recommendations will depend on final building design and placement. These recommendations will be provided at a later date when the location and layout of the proposed buildings and improvements for each lot is known. B. Slopes All slopes should be landscaped with types of plants and planting that do not require excessive irrigation. Excess watering of slopes should be avoided. Slopes left unplanted will be subject to erosion. The irrigation system should be installed in accordance with the governing agencies. Water should not be allowed to flow over the slopes in an uncontrolled manner. Until landscaping is fully established, plastic sheeting should be kept accessible to protect the slopes from periods of prolonged and/or heavy rainfall. Berms should be constructed along the top edges of all fill slopes. In no case should water be allowed to pond or flow over slopes. VII. GENERAL INFORMATION It should be noted that the characteristics of as-compacted fill may change due to post- construction changes from cycles of drying and wetting, water infiltration, applied loads, characteristics such as in strength behavior, compressibility behavior, volume change behavior, permeability, etc. This office is to be notified no later than 2 p.m. on the day before any of the following operations begin to schedule appropriate testing and/or inspections. A Fill placed under any conditions 12 inches or more in depth, to include: 1. Building pads. 2. _street improvements, sidewalks, curbs and gutters. 3. Utility trench backfills. 4. Retaining wall backfills. 5. The spreading or placement of soil obtained from any excavation (spoils from footings, underground utilities, swimming pools, etc.).
