(GSI) is providing this summary of our observation and testing services during mitigative grading within Phase 16, Lots 109, 110, 147, 148, 149, and 150, and the Model Build Out Phase, Lots 105, 106, 107, 108 of Planning Area 17, at Robertson Ranch, East Village Subdivision (Palo Verde) in the City of Carlsbad, California. The purpose of remedial grading was to reprocess the subject lots in accordance with recommendations presented in Reference Nos. 1 and 2. For the subject, very low to low expansive, lots (Phase 16 only) earthwork minimally consisted of processing the upper 12 inches of existing fill soil across, compacting and moisture conditioning to at least 90 percent at, or above the soils optimum moisture content. For the subject, medium expansive lots (Model Build Out Phase only), earthwork consisted of removing the upper 12 inches of existing fill soil across the lots. Once removals were completed, the exposed bottoms were processed, moisture conditioned and compacted to a depth of 12 additional inches, then brought to grade with compacted fill, such thatthe upper 24 inches has been reprocessed. Where tested, reprocessed and/or fill material was compacted to at least 90 percent relative compaction, at 2 percent to 3 percent above the soils optimum moisture content per ASTM D 1557 (see Reference No. 1) per GSJ recommendations. Where tested, reprocessed and/or fill material was compacted to at least 90 percent relative compaction, at the recommended moisture contents per ASTM D 1557, in accordance with GSI recommendations (see Reference No. 1). Based on our observations and testing, the building pads appear to have been prepared in general accordance with the recommendations provided by this office (see Reference Nos. 1, 2, and 3), and are considered suitable for development from a geotechnical standpoint. Field Observation and Testing Field density tests were performed using nuclear (densometer) ASTM test method D 6938 (Procedure A). The test results taken during grading operations are presented in the attached copies of our "Field Testing Reports." The laboratory maximum dry density and optimum moisture content for the major soil type within this construction phase were determined in general accordance with test method ASTM D 1557. The following table presents the results: SOIL SL TYPE j I MAXIMUM DENSITY (PCF) MOISTU 11 RE CONTENT (PERCENT) A - Brown, Silty SAND 127.0 10.0 B - Dark Brown, Clayey SAND 114.0 13.0 C - Gray Brown, Clayey SAND 120.5 13.5 E - Dark Brown Silty SAND w/clay 126.0 11.0 Field compaction testing indicates that the soils appear to meet the minimum compaction requirements previously established and adopted by the City of Carlsbad (i.e., at least 90 percent relative compaction per ASTM D 1557), and recent tests also indicate over optimum soil moisture content, in general accordance with GSl's reports (Reference Nos. 1 and 3). Should a significant (i.e., three to seven days) period of time pass prior to slab construction, additional moisture conditioning and/or re-establishing consistency, as well as pad subcirade proof testing may be necessary, prior to placement of the underslab vapor retarder (see Reference Nos. 1, and 3).

Page 2 Foundation Design/Construction Unless specifically superceded herein, the findings, conclusions, and recommendations presented in Reference No.2 and No. 3, are generally considered valid and applicable with respect to the construction and development of the subject building pads. Based on our review of Reference No. 3, the subject lots within Phase 16 (Lots 109, 110, 147, 148, 149, and 150) are categorized as foundation Category IPT, based on the as-built fill thickness across each lot, and soil expansion potential. The subject lots within the Build Out Phase (Lots 105, 106, 107, and 108) are categorized as foundation Category lIPT, based on the as-built fill thickness across each lot, and soil expansion potential. If building code updates are adopted prior to the development of these pads, an additional geotechnical update report may be necessary. Based on a review of the precise grading plans (Reference No. 4), foundations for fireplace pop outs, and potentially some isolated exterior footings may be impacted by the proximity to planned side yard drainage swales and side yard subdrain trenches. In order to mitigate the potential for settlement, these footings may need to be deepened. In cross section, deepened footings should extend to a bearing depth of at least 6 inches below the bottom of the adjacent swale flow line elevation or deepened below a 1:1 project extending up and away from the bottom outside edge of the subdrain trench, whichever is deeper. Additional footing depths ranging from 6 to 12 inches (total tooting embedment of 18 to 30 inches) should be anticipated locally. Closure The materials encountered on the project site and utilized for our analysis are believed representative of the area; however, soil and bedrock materials vary in character between excavations and natural outcrops or conditions exposed during mass grading. Site conditions may vary due to seasonal changes or other factors. Inasmuch as our study is based upon our review and engineering analyses and laboratory data, the conclusions and recommendations are professional opinions. These opinions have been derived in accordance with current standards of practice, and no warranty, either express or implied, is given. Standards of practice are subject to change with time. GSI assumes no responsibility or liability for work or testing performed by others, or their inaction; or work performed when GSI is not requested to be onsite, to evaluate if our recommendations have been properly implemented. Use of this report constitutes an agreement and consent by the user to all the limitations outlined above, notwithstanding any other agreements that may be in place. In addition, this report may be subject to review by the controlling authorities. Thus, this report brings to completion our scope of services for this portion of the project.

(OSI) is providing this summary of our observation and testing services during mitigative grading within Phase 15, Lots 111, 112, 113, 144, 145, and 146 of Planning Area 17, at Robertson Ranch, East Village Subdivision in the City of Carlsbad, California. The purpose of remedial grading was to reprocess the subject lots in accordance with recommendations presented in Reference Nos. 1 and 2. For the subject, very low t0 low expansive, earthwork minimally consisted of processing the upper 12 inches of existing fill soil across, compacting and moisture conditioning to at least 90 percent at, or above the soils optimum moisture content. Where tested, reprocessed and/or fill material was compacted to at least 90 percent relative compaction, at the recommended moisture contents per ASTM D 1557, in accordance with GSI recommendations (see Reference No. 1). Based on our observations and testing, the building pads appear to have been prepared in general accordance with the recommendations provided by this office (see Reference Nos. 1, 2, and 3), and are considered suitable for development from a geotechnical standpoint. Field Observation and Testing Field density tests were performed using nuclear (densometer) ASTM test method D 6938 (Procedure A). The test results taken during grading operations are presented in the attached copies of our "Field Testing Reports." The laboratory maximum dry density and optimum moisture content for the major soil type within this construction phase were determined in general accordance with test method ASTM D 1557. The following table presents the results: Field compaction testing indicates that the soils appear to meet the minimum compaction requirements previously established and adopted by the City of Carlsbad (i.e., at least 90 percent relative compaction per ASTM D 1557), and recent tests also indicate over optimum soil moisture content, in general accordance with GSI's reports (Reference Nos. 1 and 3). Should a significant (i.e., three to seven days) period of time pass prior to slab construction, additional moisture conditioning and/or re-establishing consistency, as well as pad subcirade proof testing may be necessary, prior to placement of the undersiab vapor retarder (see Reference Nos. 1, and 3). Foundation Design/Construction Unless specifically superceded herein, the findings, conclusions, and recommendations presented in Reference No. 2, are generally considered valid and applicable with respect to the construction and development of the subject building pads. Based on our review of Reference No. 3, Lot Nos. 115, 141, and 142 are categorized as foundation Category IIPT, based on the as-built fill thickness across each lot (Reference No. 3). Lots 114, 116, and 143 are categorized as foundation Category IlIPT, based on the as-built fill thickness across each lot (Reference No. 3). If building code updates are adopted prior to the development of these pads, an additional geotechnical update report may be necessary.

In order to mitigate the potential for settlement, these footings may need to be deepened. In cross section, deepened footings should extend to a bearing depth of at least 6 inches below the bottom of the adjacent swale flow line elevation or deepened below a 1:1 project extending up and away from the bottom outside edge of the subdrain trench, whichever is deeper. Additional footing depths ranging from 6 to 12 inches (total footing embedment of 18 to 30 inches) shoUld be anticipated locally. Closure The materials encountered on the project site and utilized for our analysis are believed representative of the area; however, soil and bedrock materials vary in character between excavations and natural outcrops or conditions exposed during mass grading. Site conditions may vary due to seasonal changes or other factors. Inasmuch as our study is based upon our review and engineering analyses and laboratory data, the conclusions and recommendations are professional opinions. These opinions have been derived in accordance with current standards of practice, and no warranty, either express or implied, is given. Standards of practice are subject to change with time.

Dear Mr. Rodgers and Mr. McDonnell: GeoSoils, Inc. (GSI) is providing this summary of our observation and testing services during mitigative grading within Phase 6 Lots 13 through 19, and Phase 7 Lots 7 through 12 of Planning Area 17, at Robertson Ranch, East Village Subdivision in the City of Carlsbad, California. The purpose of remedial grading was to reprocess the subject lots in accordance with recommendations presented in Reference Nos. 1 and 2. For the subject, low expansive Lots 1 and 2, earthwork minimally consisted of processing the upper 12 inches of existing fill soil across, Compacting and moisture conditioning to at least 90 percent at, or above the soils optimum moisture content. For medium expansive (Expansion Index [E. 1.]51-90) Lots 3 through 9, earthwork consisted of removing the upper 12 inches of existing fill soil across the lots. Once removals were completed, the exposed bottoms were processed, moisture conditioned and compacted to a depth of 12 additional inches, then brought to grade with compacted fill, such that the upper 24 inches has been reprocessed, and moisture conditioned to approximately 2-3 percent above the soils optimum moisture content. For the subject, highly expansive (Expansion Index [El.] 91- 130) Lots 10 through 19, earthwork consisted of removing the upper 12 inches of existing fill soil across the lots. Once removals were completed, the exposed bottoms were processed, moisture conditioned and compacted to a depth of 12 additional inches, then brought to grade with compacted fill, such that the upper 24 inches has been reprocessed, and moisture conditioned to at least 3-4 percent above the soils optimum moisture content. Where tested, reprocessed and/or fill material was compacted to at least 90 percent relative compaction, at the recommended moisture contents per ASTM D 1557, in accordance with GSI recommendations (see Reference No. 1). Based on our observations and testing, the building pads appear to have been prepared in general accordance with the recommendations provided by this office (see Reference Nos. 1, 2, and 3), and are considered suitable for development from a geotechnical standpoint. Field Observation and Testing Field density tests were performed using nuclear (densometer) ASTM test method D 6938 (Procedure A). The test results taken during grading operations are presented in the attached copies of our "Field Testing Reports." The laboratory maximum dry density and optimum moisture content for the major soil type within this construction phase were determined in general accordance with test method ASTM D 1557. The following table presents the results: - - SOIL TYPE MAXIMUMI DENSITY (PCF) MOISTURE CONTENT (PERCENT) - B-Dark Brown, Clayey SAND 114.0 13.0 C - Gray Brown, Clayey SAND 120.5 13.5 0- Yellow Brown, Clayey SAND 119.5 11.5 J - Gray, Clayey SAND 121.0 12.5 Field compaction testing indicates that the soils appear to meet the minimum compaction requirements previously established and adopted by the City of Carlsbad (i.e., at least 90 percent relative compaction per ASTM D 1557), and recent tests also indicate over optimum soil moisture content, in general accordance with GSI's reports (Reference Nos. 1 and 3). Should a significant (i.e., three to seven days) period of time pass prior to slab construction, additional moisture conditioning and/or re-establishing consistency, as well as pad subcirade proof testing may be necessary, prior to placement of the underslab Brookfield Homes W.O. 5949-1317-SC PA-17, Phases 6 & 7, Robertson Ranch April 15, 2014 File:e:\wpl2\5900\5949b17.ph6.7.cro Geoods, Inc. Page 2 vapor retarder (see Reference Nos. 1, and 3). Foundation Design/Construction Unless specifically superceded herein, the findings, conclusions, and recommendations presented in Reference No. 2, are generally considered valid and applicable with respect to the construction and development of the subject building pads. Based on our review of Reference No. 3, Lot Nos. 1 and 2 are categorized as foundation Category IPT. Lots 3 through 9 are categorized as foundation Category IIPT, based on medium expansive soil conditions (Reference No. 3). Lots 10 through 19 are categorized as foundation Category lIlPI, based on highly expansive soil conditions (Reference No. 3). If building code updates are adopted prior to the development of these pads, an additional geotechnical update report may be necessary. Based on a review ofthe precise grading plans (Reference No. 4), foundations for fireplace pop outs, and potentially some isolated exterior footings may be impacted by the proximity to planned side yard drainage swales and side yard subdrain trenches. In order to mitigate the potential for settlement, these footings may need to be deepened. In cross section, deepened footings should extend to a bearing depth of at least 6 inches below the bottom of the adjacent swale flow line elevation or deepened below a 1:1 project extending up and away from the bottom outside edge of the subdrain trench, whichever is deeper. Additional footing depths ranging from 6 to 12 inches (total footing embedment of 18 to 30 inches) should be anticipated locally. Closure The materials encountered on the project site and utilized for our analysis are believed representative of the area; however, soil and bedrock materials vary in character between excavations and natural outcrops or conditions exposed during mass grading. Site conditions may vary due to seasonal changes or other factors. Inasmuch as our study is based upon our review and engineering analyses and laboratory data, the conclusions and recommendations are professional opinions. These opinions have been derived in accordance with current standards of practice, and no warranty, either express or implied, is given. Standards of practice are subject to change with time. GSI assumes no responsibility or liability for work or testing performed by others, or their inaction; or work performed when GSI is not requested to be onsite, to evaluate if our recommendations have been properly implemented. Use of this report constitutes an agreement and consent by the user to all the limitations outlined above, notwithstanding any other agreements that may be in place. In addition, this report may be subject to review by the controlling authorities. Thus, this report brings to completion our scope of services for this portion of the project.
