Tettemer and Associates (Reference 1). RMA Group Inc. worked in conjunction with the designer, Tettemer and Associates, and the project civil engineer, Madole and Associates, to verify that the construction of the infiltration basins, wetland areas and onsite storm drain improvements were constructed in accordance with the project plans (Reference 3). 1.03 Flood Control Infiltration System Generally, the infiltration system consists of a 30 inch thick sand filter underlain by an 18 inch thick gravel layer. The material for the sand filter was a washed No. 12 silica sand conforming to the following gradation: Sieve Size Percent Passing #4 100 #8 96 -100 #16 5 -15 #30 0 -10 #50 0 -10 #100 0 -5 #200 0 -1 The material for the gravel layer was a washed No. 2 gravel conforming to the following gradation: Sieve Size Percent Passing 3 100 2" 90 -100 1 ' /z" 50 -100 1 5 -40 3 /4 " 0 -15 3/8" 0 -15 RMA Job N° 98- 038 -02 Page 1 GEOTECHNICAL CONSULTANTS RMA GMUP GEOTECHNICAL CONSULTANTS Sierra Lakes Land Co., LLC Tract No. 14794 Fontana, CA November 3, 2000 A typical section of the infiltration basin is shown below: TURFED GOLF COARSE FAIRWAY �- FILTER FABRIC LINING 30" THICK SAND FILTER FILTER FABRIC LINING OVER GRAVEL LAYER SUBGRADE SOIL --/ "--- 18" THICK GRAVEL LAYER TYPICAL INFILTRATION BASIN SECTION 1.04 Scope of Work RMA Group observed various aspects of the construction of the infiltration basins, wetland areas and storm drain system and performed materials tests on the various construction materials incorporated in the construction. RMA Group's representatives observed and tested the following elements of the infiltration basins: • Observed the preparation of the subgrade soils at the bottom of each infiltration basin and performed sieve analyses on the subgrade soils at the bottom of each basin to classify the soil types encountered. • Observed the placement of the gravel bed and performed sieve analyses on the gravel materials to verify conformance with the project specifications. • Observed the placement and protection of the filter fabric. • Observed the placement of the filter sand and performed sieve analyses on the filter sand materials to verify conformance with the project specifications. u 8 -02 N° 9 -0 RMA Job 8 3 Page 2 U VRM�A 0 Performed in place density (compaction) tests and laboratory maximum density tests on the backfill of onsite storm drain trenches. Performed compression tests on the concrete delivered to the project for structures with design compressive strengths exceeding 3,000 psi. Performed sieve analyses and chemical tests on the topsoil placed within the wetlands. 2.00 F INDINGS 2.01 Infiltration Basin Construction r D I LI GEOTECHNICAL CONSULTANTS Sierra Lakes Land Co., LLC Tract No. 14794 Fontana, CA November 3, 2000 Materials tests were performed during the construction of the onsite storm drain system and wetland areas on the following: The infiltration basins were excavated to design grades and prepared to receive the gravel backfill by scarifying or blade mixing the upper surface of the exposed soils. Construction equipment was prohibited from compacting the exposed soils prior to placement of the gravel materials. Gravel, consisting of native screened materials was placed over the subgrade soils and spread across the basins without disturbing the subgrade soils. Filter fabric was then placed over the gravel layer and the outer portions of the basins were backfilled with native soils. Additional filter fabric was installed along the edges of the backfilled soils within the areas of the filter sand. Damaged filter fabric was replaced prior to the installation of the filter sands. The filter sands were then placed within the basins to the design finished grades. The subgrade soils were tested to verify that the anticipated soil types were present at the bottom of each basin. The results of these tests verified that the appropriate soils types were encountered. The gravel materials were tested prior to backfilling to verify that the materials utilized met the project specifications. The results of these tests indicate that the materials utilized generally complied with the project specifications. During the course of construction, the required filter sand was not locally available. Therefore, various samples from several manufacturers were sampled and tested to verify conformance with the specifications for the sand filter. Several materials were evaluated for possible blending with other sands to extend the amount of material available for use at the project. During construction, some of the sand materials delivered to the project failed to meet the project specifications. These materials were rejected and not utilized in the infiltration system when in our opinion the gradation would compromise the permeability of the filter sand.

Tettemer and Associates, Ltd. Max Vahid, President Alan A. Swanson, Senior Vice President John S. Wolter, Senior Project Manager I AS -BUILT CERTIFICATION OF INFILTRATION BASIN STORAGE CAPACITY Background In September of 1997, John M. Tettemer and Associates. Ltd. (JMTA) prepared the Sierra Lakes Integrated Flood Control, Water Conservation and Storm Water Quality Management SpielIz - Summay Report for Lewis Homes of California (LHOC). In January of 1999, Addendum #/ to the Summary Report was provided. The initial report provided the conditions, criteria and assumptions to be used in implementing the system and specified the infiltration basin storage volumes, gravel areas. and sand areas. The addendum developed an alternative Design Infiltration Rate Curve and refined flood routing studies based on the addition of two infiltration test pits, revisions to the Golf Course grading plans, new criteria for calculation of l00 -\ ea' storm runoff hydrographs, and the establishment of two specific flood design conditions. Findings In July of 1999, Madole and Associates, Inc. surveyed all infiltration basins and prepared plots of As -built vs. Design cross sections. John M. Tettemer and Associates reviewed these sections to verify the storage capacity of the As -built infiltration basins. The appendix to this report includes the As -built storage capacity calculations, topographical maps, and cross - sections prepared by Madole and Associates comparing As -built vs. Design storage capacity for each infiltration basin. In general, the As -built condition provides slightly less storage capacity than designed. However, the increase in peak water surface elevation (WSEL) is still acceptable when compared with the minimum Pad Elevation for all but two locations. Under the normal Design Condition, the Practice Range Basin No. 3 reaches a peak WSEL of 1607.70 ft, 0.20 ft higher than the minimum Pad Elevation of 1607.50 ft for this area. Under the assumed Failure Mode Condition, Basin No. 1 between the 14 and 15 fairways reaches a peak WSEL of 1589.13 ft, 0.13 ft higher that the minimum Pad Elevation of 1589.00 ft for this area. The results of all basin analyses have been summarized in Table 1 below. Conclusions In light of these findings, the As -built infiltration basins 2, 4, 5, 6, 7, 8, 9, and 10 provide sufficient storage capacity to satisfy both design conditions. The Design Condition operational WSEL of 0.20 ft above the minimum pad elevation at Basin No. 3 is considered acceptable for the following reasons. • The additional runoff from offsite drainage area included in the Design Condition is conservative and will not be a part of the Ultimate Condition. • The Design Condition conservatively excludes all infiltration except for infiltration through the sand filter portion of the basins. • Most importantly, this excess only results in a decrease from 3 ft to 2.8 ft of freeboard so that there is still no risk to adjacent property. The Failure Mode Condition WSEL of 0.13 ft above the minimum pad elevation at Basin No. 1 is considered acceptable for the following reasons. • The 0.13 ft is relatively insignificant within the context of the hydrologic /hydraulic calculations. • A reduction in the storage capacity of Basin No. I would effectively increase the duration of discharge to Street "A" through the overflo\k area and not increase peak WSEL as conservatively assumed in this analysis. 10 V ESSiO�, L OR Cop) Nn C22695 a rn wj EXP. ff9l CIVI\- Z OF C.pl PIR so r � r V G" Pa", e G SIERRA LAKES INFILTRATION BASINS As -Built vs. Design Comparison A 0 H--- " " " r"l U " W31 an TABLE 1 SIERRA LAKES As -Built vs. Design Analysis of Infiltration Basin Storage Capacity Infiltration Basin No. Location As -Built Vol Effect on WSEL (ft) Design Condition' Peak Stage WSEL + 3 ft (3) Failure Mode Condition (2) Peak Stage WSEL + 0 ft Minimum Pad Elev.
