GEOCON GEOTECHNICAL CONSULTANTS 1 Project No. 06105-12-07 UI March:11, 2003 Real Estate Collateral Management Company C/0 Morrow Development Incorporated 1903 Wright Place, Suite 108 Carlsbad; California. 92008 Attention: Mr. Tim O'Grady I Subject: RANCHO, SANTA FE ROAD STATIONS 174+50 THROUGH 217+90 CARLSBAD, CALIFORNIA FINAL REPORT OF TESTING AND OBSERVATION SERVICES PERFORMED DURING SITE GRADING Gentlemen: In accordance with your request and our proposal dated May 16, 2002, we have provided compaction testing and observation services during the grading of the subject roadway. Our services were performed during the period of May. 20, 2002 through March 7, 2003. The scope of our services included the following: Observing the grading operation, including the removal and/or processing of loose topsoils, alluvium, and undocumented fill. Performing in-place dry density and moisture content tests within fill materials placed and compacted at the site. Performing laboratory tests to aid in evaluating the dry density and moisture content and shear strength characteristics of various soils encountered and/or used for fill. Performing field and laboratory grain-size analysis of the fill placed in the upper 8 feet of the street right-of-way. Preparing an "As-Graded" Geologiô Map. Preparing this final report of grading. The purpose of this report is to document that the grading for the realignment of Rancho Santa Fe Road Stations 174+50 through 217+90 has been performed in substantial conformance with the 6960 Flanders Drive 0 San Diego, California 92121-2974 • Telephone (858) 558-6900 U Fax (858) 558-6159 Li 1 recommendations of the project geotechnical report and that fill materials have been properly placed and compacted. It should be noted that the grading for the, easterly slope zone at station 200+00 through 201+00 was postponed to maintain access for the surrounding residential development, therefore the grading for the slope zone is excluded from this report. Additional testing and observation for this area will' be reported in an addendum when the. grading is complete. GENERAL The grading contractor for the project was Erreca's Incorporated of 'Lakeside, California. Grading plans for the project were prepared by Hunsáker and Associates and are entitled Grading and Improvement Plans For Rancho Santa Fe Road, Sheet Nos. 1 through 30, dated June 3, 2002. The grading plans were used as the base map for the "As-Graded" Geologic Map (Figures 1 through 3, map pocket). The project 'soils report is entitled Supplemental Geotechnical Investigation Report Design Stage 2 prepared by Agra Earth & Environmental, Inc. dated November 10, 1998. The following reports were also prepared for the project: Update Geotechnical Investigation Villages of La Costa—The Oaks, Carlsbad, California, prepared by Geocon Incorporated, dated August 3, 2001 (Project No. 06105-12-04). Supplemental Soil and Geologic Investigation for Rancho Santa Fe Road Alignment, Carlsbad, California, prepared by Geocon Incorporated, dated January 8, 1990 (Project No. D-4367-H02). Soil and Geologic Reconnaissance for Rancho Santa Fe Road Alignment, prepared by Geocon Incorporated, dated June 30, 1989 (Project No. D-43674101). References to elevations and locations herein were based on surveyor's or grade checker's stakes in the field and/or interpolation from the referenced grading plans. 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 The realignment of Rancho Santa Fe Road stations 174+50 through 217+90 bisects the Villages of I La Costa - The Oaks residential development and lies west of the proposed "MAG" Property development and north of La Costa' Avenue in Carlsbad, California. Originally, Rancho Santa Fe I Road stations 174+50 through 217+90 was designed as a stand-alone roadway to be constructed by the City of Carlsbad. Subsequently, site development for the Villages of La Costa - The Oaks residential development was designed to incorporate the grading for Rancho Santa Fe Road Is Project No. 06105-12-07 -2 - ' . March 11, 2003 I ' stations 174+50 through 217+90. Prior to grading, the site consisted of a dominant north-south- trending canyon fed by several smaller northeast-southwest trending canyons. Grading for the site consisted of daylight cuts and fills on the order of 40 and 95 feet, respectively, to achieve the finish grade elevations. Grading began with the removal of brush and vegetation from the area to be graded. The brush was then exported. Topsoil and alluvial soils were removed to expose formational material. Within these areas, and prior to placing fill, the exposed (overexcavated) ground surface was scarified, moisture conditioned as necessary, and compacted. Excavations exposing metavolcanic rock were not scarified. Fill soils derived from on-site excavations were then placed and compacted in layers until the design elevations were attained. Portions of the roadway that exposed metavolcanic rock at finished grade were undercut to a depth of approximately 1 foot below the deepest utility and replaced with properly compacted fill soil. Fill Materials and Placement Procedures The on-site fill materials generally varied between angular gravels and boulders produced by oñsite blasting of hard metavolcanic rock to clayey fine sands, sandy to silty clay and sandy to clayey gravels. Structural fill placed and compacted to construct the roadway embankment can be classified into three zones: (1) Select Fill - Material placed in the upper 8 feet of the roadway consisting of soil fill with a maximum particle dimension of 3-inches; (2) Upper Fill - Material placed within the upper 16 feet of the-roadway embankment and below 8 feet from the roadway subgrade consisting of "soil-rock" fill with a maximum particle dimension of 12-inches; (3) Lower Fill - Material placed below 16 feet from roadway subgrade consisting of "soil-rock" fill and "rock" fill with a maximum particle dimension of 36-inches. Placement procedures• for "rock" and "soil-rock" fills consisted of spreading and compacting the materials with a D9 Caterpillar bulldozer or equivalent with a maximum lift size of 3 feet. Materials placed as "rock" and "soil-rock" fills were watered heavily during spreading to place finer grained material between the rock. During the placement of each lift, compactive effort was applied to the fill by wheel-rolling with loaded rock trucks such that the entire lift was compacted. Soil fills were placed in lifts no thicker than would allow for adequate bonding and compaction. The soil fill was moisture conditioned, as necessary, and mixed during placement and then compacted utilizing conventional heavy-duty compaction equipment. During the grading operations, compaction procedures were observed and in-place density tests were performed to evaluate the dry density and moisture content of the "soil" and "soil-rock" fill material. Project No. 06105-12-07 - 3 - March ii, 2003 The in-place density tests were performed in general conformance with ASTM Test Method D 2922-91, Standard Test Method for Density of Soil and Soil-Aggregate in Place by Nuclear Methods. Test excavations in "soil-rock" and "rock" fills containing larger rock particles typically resulted in significant soil, disturbance yielding unreliable in-place density test results. When this occurred, test pits were excavated and observed for the condition of the rock and soil matrix with respect to "seating" and void content. "Soil-rock" and "rock" fill placement procedures were observed, and documented, and in-place density testing was performed when practical. In-place moisture tests were performed on "soil-rock" and "rock" fill materials where conventional in-place density testing was not practical. These in-place moisture tests have been summarized with a prefix "M" in Table I to designate an in-place moisture test only. The results presented in Table I are for the Rancho Santa Fe Road stations 174+50 through 217+90 fill prism as originally designed; as such, some tests fall within lots associated with the surrounding residential development. Using methods suggested by AASHTO T224-86, corrections were made to the laboratory maximum dry density and optimum moisture content on fill soils being tested containing rocks larger than 3/4 inch. The values of maximum dry density and optimum moisture content presented on Table I reflect these corrections. In general, the in-place density test results indicate that the fill soil has a dry density of least 90 percent of the laboratory maximum dry density near to slightly above optimum moisture content at the locations tested. Moisture test results obtained from test excavations in "soil-rock" or "rock" fills where conventional density testing was not practical indicate that, in general, the "soil matrix" possesses moisture contents near or above the optimum moisture content. In addition, in-place density tests results indicate that the upper approximately 3 feet of fill placed in the roadway has a dry density of at least 95 percent of the laboratory maximum dry density near to slightly above optimum moisture content. The approximate locations of the in-place density and moisture content tests are shown on the As-Graded Geologic Map (Figures 1 through 3). 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 1557-00), .shear strength (ASTM D 3080-98), expansion potential (ASTM D 4829-95) and particle size analysis of soils (ASTM D 422-63). The results of the laboratory tests are summarized in Tables II through V. Slopes The project slopes consisted of cut and fill slopes constructed at inclinations of 2:1 (horizontal: vertical) or flatter, with maximum heights of approximately 40 and 55 feet, respectively. Fill slopes were constructed such that the outer 15 feet consisted of "Upper Fill" material (12-inch Project No. 06105-12-07 -4- March 11, 2003' I maximum particle dimension). In general, fill slopes for Rancho Santa Fe Road stations 174+50 through 217+90 were overbuilt and cut back to finish grade. Fill slopes were then "track walked" I with a D9 Caterpillar bulldozer or equivalent. In our opinion, the fill slopes possess adequate factor of safety against deep-seated or surficial instability. Cut slopes were observed and mapped by an I engineering geologist for fractures and jointing systems that could affect slope stability. Cut slopes should be stable with respect to deep-seated failure and surficial sloughage up to the proposed maximum height of 40 feet. 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. I Subdrains Subdrains were installed at the general locations shown on the as-graded geologic map (Figures 1 through 3). In addition, the subdrains were "as-built" for location and elevation by the project civil engineer. The subdrains generally consisted of a 6 to 8-inch diameter PVC perforated pipe placed in crushed aggregate gravel surrounded by Mirafi 140N (or equivalent) filter fabric. The drains were typically placed at least 15 feet below grade and constructed at a gradient of at least 1 percent. The subdrain system that services Rancho Santa Fe Road stations 174+50 through 217+90 ties into subdrains for the Villages of La Costa - The Oaks Development which ultimately outlets near La Costa Avenue at an energy dissipation headwall. SOIL AND GEOLOGIC CONDITIONS The soil and geologic conditions encountered during grading were found to be similar to those I described in the project geotechnical report. Stiff to very hard, silty claystones and sandstones of the Santiago Formation (Ts), were exposed in canyon cleanouts at the south end of the road realignment. It should be noted that the Santiago Formation was previously mapped as Delmar Formation (Geologic Maps of the Northwestern Part of San Diego County, California, DMG Open File Report 96-02). Completely weathered to fresh, highly fractured and in areas highly altered, moderately I strong to very strong andesitic volcanic rock of the Santiago Peak Volcanics (Jsp) was exposed at grade and in canyon cleanouts for a majority of the roadway. Compacted fill soil was placed in areas of proposed fill and is designated as Qcf on Figures 1 through 3. Stockpiled "Upper Fill" material was placed north of station 217+90 at the north end of the realignment and is mapped as undocumented fill (Qudf). In addition, the roadway was overexcavated a minimum of 8 feet where I metavolcanic rock was exposed at finished grade and replaced with compacted "soil" fill; It should also be noted that the Santiago Formation at Rancho Santa Fe Road stations 174+50 through 178+00 I was mined (overexcavated) extensively. The bottom elevations shown on the "As-graded" geologic map (Figures 1 through 3) reflect this mining. 'I Project No. 06105-12-07 -5- March ll,2003 I 1. I Approximately 20,000 cubic yards of stockpiled "Upper Fill" material was placed at the north end of Rancho Santa Fe Road stations 218+50 through 225+00. This material was placed for the future grading of Rancho Santa Fe Road north of station 217+90. This grading will be performed by the City of Carlsbad. No remedial grading or testing was performed for any stockpiled material. L0i City of Carlsbad specifications for the upper 3 feet of fill placed within the roadway require that the material used have a "low" expansion potential (Expansion Index of 50 or less) as defined by the Uniform Building Code (UBC) Table 18-I-B. Where "low" expansive material was not available, the use of medium expansive soil was necessary. Based on field observations and laboratory tests, the upper approximately 3 feet of fill placed within the roadway possesses a "low" to "medium" expansion potential (Expansion Index of 90 or less) as defined by the Uniform Building Code (UBC) Table 18-I-B. Where "low" expansive material was not available, material of the least expansion ET14-SIVFC, index available was used. The enclosed "As-Graded" Geologic Map (Figures 1 through 3) depicts the general geologic conditions observed. No soil or geologic conditions were observed during grading which would preclude the continued development of the property as planned. 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 I with the recommendations of the previously referenced project soil report. Soil and geologic conditions encountered during grading which differ from those anticipated by the project soil report are not uncommon. Where such conditions required a significant I modification to the recommendations of the project soil report, they have been described herein. - 2.0 Future Grading 1 2.1 Any additional grading performed at the site should be accomplished in conjunction with our observation and compaction testing services. Grading plans for any future grading should be reviewed by Geocon Incorporated prior to finalizing. All trench and wall backfill should be compacted to a dry density of at least 90 percent of the laboratory maximum dry density at near to slightly above optimum moisture content. This office I should be notified at least 48 hours prior to commencing additional grading or backfill operations. 10, I Project No. 06105-12-07 -6- March .11, 2003 3.0 Slope Maintenance 31 Slopes that are steeper than 3:1 (horizontal: vertical) may, under conditions which are both difficult to prevent and predict, be susceptible to near surface (surficial) slope instability. The instability is typically limited to the outer three feet of a portion of the slope and usually does not directly impact the improvements on the pad areas above or below the slope. The occurrence of surficial instability is more prevalent on fill slopes and is generally preceded by a period of heavy rainfall, excessive irrigation, or the migration of- subsurface seepage. The disturbance and/or loosening of the surficial soils, as might result from root growth; soil expansion, or excavation for irrigation lines and slope planting, may also be a significant contributing factor to surficial. instability. It is, therefore, recommended that, to the maximum extent practical: (a) disturbed/loosened surficial soils be either removed or properly recompacted, (b) irrigation systems be periodically inspected and maintained to eliminate leaks and excessive irrigation, and (c) surface drains on and adjacent to slopes be periodically maintained to preclude ponding or erosion. It should be noted that although the incorporation of the above recommendations should reduce the potential for surficial slope instability, it will not eliminate the possibility, and, therefore, it may be necessary to rebuild or repair a portion of the project's slopes in the future. 4.0 Drainage 4.1 Adequate drainage provisions are critical to the future performance of the project. Under no circumstances should water be allowed to pond. The building pads and sheet-graded areas should be properly finish graded so that drainage water is directed away from foundations, pavements, concrete slabs, and slope tops to controlled drainage devices. 4.2 All underground utilities should be leak free. Utility and irrigation lines should be checked periodically for leaks for early detection of water infiltration and detected leaks should be repaired promptly. Detrimental soil movement could occur if water is allowed to infiltrate the soil over a prolonged period of time. 4.3 Landscaping planters adjacent to paved areas are not recommended due to the potential for surface or irrigation water to infiltrate the pavement's subgrade and base course. We recommend that subdrains to collect excess irrigation water and transmit it to drainage structures; or impervious above-grade planter boxes be used. In addition, where landscaping is planned adjacent to the pavement, we recommended construction of a cutoff Project No.06105-12-07 - 7 - March 11, 2003 1 Shane Rodacker RCE 63291 ESs r No. 63291 ul Exp6t3W06 k.
