The City requires DMA map, not HMOD map. Revise DMA map to clearly delineate the limits of the following (see also red-lined comments on the SWMP report): a) Boundary of Basin 1 b) Proposed pervious area (pavers)-consider as separate DMA 1.3 and show the area in sq. ft. c) Proposed landscape area-DMA 1.2, show the area in sq. ft. d) Proposed impervious area (roof area)-DMA 1.1, show the area in sq. ft. e) Show the IMP-in this case includes the underground storage (indicate area in sq. ft.) and the Modular Wetland (indicate the model no. and size). 6) The water quality volume (WQV) shown in the Modular Wetland (MWS-linear) volume based sizing calculations is 3,921 CF. Where did this number came from? Provide calculations/explanation. The calculated WQV is 1,498 CF per the calculations included in the attachment 5. Please revise as necessary. 7) Previous comment: Provide a soils update letter to include design recommendations for proposed pervious pavers with underground storage and modular wetland. 8) Provide a separate BMP Plan using the City standard BMP plan template provided in the city website (see attached sample): http://www.carlsbadca.gov/services/depts/landev/landdev.asp 9) Please comply with all red-lined comments on the SWMP report. Drainage Report: 10) On page 2, under proposed conditions, it is stated that the pervious pavement will provide water quality, hydromodification and 100 year storm mitigation. This statement is incorrect. Pervious pavement is considered an LID feature (low impact design feature) but cannot be used as a treatment control BMP nor a hydromodification facility. Per the SWMP report, the proposed Modular Wetland is the treatment control BMP and the proposed underground storage below the pervious pavers is used for hydromodification and 100 year storm mitigation.

This statement appears to be in error since the unit of area is square inch. Do you mean 12 square inch restrictor area? Or 12 inch in diameter restrictor orifice/pipe? Please clarify. This restrictor area is not shown on the plans. Please show the location of the restrictor area and provide details on the plans and the report. 12) On page 9 of the Attachment 4, Detention Design, please indicate the dimensions of the detention basin (length, width and height). It appears that the detention facility is the proposed underground storage under the pervious pavers. The detention calculations shows a 12" dia. pipe but it is not clear where it is used in the detention calculations. The details provided on the plans does not show a 12" pipe. Please clarify and provide a more detailed detention basin and outlet structure on the plans and in the report. see additional red-lined comments in the report. 13) On the same page 9, an orifice calculations for a stage-discharge table is shown. The orifice area used is 0.79 sq.ft. This is equal to a 0.5'' diameter orifice.

Provide mitigation measures for any increases in post development flows. Hydraulic analysis maybe required for preliminary sizing of the proposed storm drain facilities. Issues of Concern: 4) On sheet C-01, provide a summary table showing the total disturbed area, existing pervious area, existing impervious area, proposed pervious area and proposed impervious area in square feet. This information is needed to determine the increase in impervious area, post development condition. The site plan shows proposed pervious pavers on the majority of the paved areas. This project may be exempt from hydromodification requirements if the proposed impervious area is less than the existing impervious area. See HMP determination checklist on page 30 of City SUSMP, Volume 4, Engineering Standard. 5) Sheet C-08 indicates that an underground water quality modular wetland is proposed as treatment BMP for this project. Provide details and sizing calculations for these proposed facilities in the preliminary SWMP. Add proposed BMP details/cross-sections on the site plan. 6) A soils report by leighton and Associates, Inc. dated February 13, 2015 (comprised of 22 pages plus exhibits) has been incorporated into the civil plans on sheets C-12 and C-13.

The application documents submitted for this project are incomplete. Prior to next submittal, it is suggested the following items are adequately addressed. Additional items of concern may be identified upon review of the next submittal: SWMP: 1. Complete step 4 on page 3 of Form E-34 and obtain applicant's signature. 2. The project uses a proprietary product called modular wetland as Treatment Control BMP (TCBMP). Using Table 4 provided on page 13 of the project SWMP, identify the TCBMP type. It appears that this product is a high rate media filter. According to Table 4, it has medium efficiency in treating pollutants that tend to associate with fine particles and has low efficiency in treating pollutants that tends to dissolve following treatment. City SUSMP requires projects to provide the most efficient BMP such as bioretention basin to the maximum extent practicable. Please include in the SWMP narrative the project's justifications for using less efficient BMP. 3. On page 13, section 7, it is indicated that this project is subject to hydromodification. However, on Sheet C-01, the area summary table shows that the existing impervious area is 26,502 SF and is less than the proposed impervious area of 25,241 SF. Using Figure 2-1, HMP Applicability Determination, this project is exempt from hydromodification requirements provided the impervious area calculations shown on the plans are accurate (see red-lined comments on the SWMP report). If exempt, the underground storage does not need to be designed as a hydro modification facility. It is still needed as a detention basin to mitigate 100 year storm event peak flows. 4. Rectify the following inconsistencies in area calculations in the SWMP report, hydrology report and site plan and revise calculations and BMP map accordingly: SWMP report (attachment 5): Total Area: 36,069.8; Impervious area: 22, 352 SF Hydrology report (attachment 4): Total Area: 37,290 SF; Impervious area: 34,472 SF Site Plan (Sheet C-Ol & C-07): Total Area: 47,851 SF; Impervious area: 25,241 SF 5. Change the name HMOD Map to DMA map. The City requires DMA map, not HMOD map. Revise DMA map to clearly delineate the limits of the following (see also red-lined comments on the SWMP report): a. Boundary of Basin 1 b. Proposed pervious area (pavers)-consider as separate DMA 1.3 and show the area in sq. ft. c. Proposed landscape area-DMA 1.2, show the area in sq. ft. d. Proposed impervious area (roof area)-DMA 1.1, show the area in sq. ft. e. Show the IMP -in this case includes the underground storage (indicate area in sq. ft.) and the Modular Wetland (indicate the model no. and size). 6. The water quality volume (WQV) shown in the Modular Wetland (MWS-Linear) volume based sizing calculations is 3,921 CF. Where did this number come from? Provide calculations/explanation. The calculated WQV is 1,498 CF per the calculations included in the attachment 5. Please revise as necessary.

Previous comment: Provide a soils update letter to include design recommendations for proposed pervious pavers with underground storage and modular wetland. 8. Provide a separate BMP Plan using the City standard BMP plan template provided in the city website (see attached sample): http:ljwww.carlsbadca.gov/services/depts/landev/landdev.asp ,, 9. Please comply with all red-lined comments on the SWMP report. Drainage Report: 10. On page 2, under proposed conditions, it is stated that the pervious pavement will provide water quality, hydromodification and 100 year storm mitigation. This statement is incorrect. Pervious pavement is considered an LID feature (low impact design feature) but cannot be used as a treatment control BMP nor a hydromodification facility. Per the SWMP report, the proposed Modular Wetland is the treatment control BMP and the proposed underground storage below the pervious pavers is used for hydromodification and 100 year storm mitigation. 11. On page 2, under proposed conditions, it states "A 12 inch restrictor area will be needed to mitigate the increase in peak flow". This statement appears to be in error since the unit of area is square inch. Do you mean 12 square inch restrictor area? Or 12 inch in diameter restrictor orifice/pipe? Please clarify. This restrictor area is not shown on the plans. Please show the location of the restrictor area and provide details on the plans and the report. 12. On page 9 of the Attachment 4, Detention Design, please indicate the dimensions of the detention basin (length, width and height). It appears that the detention facility is the proposed underground storage under the pervious pavers. The detention calculations shows a 12" dia. pipe but it is not clear where it is used in the detention calculations. The details provided on the plans does not show a 12" pipe. Please clarify and provide a more detailed detention basin and outlet structure on the plans and in the report. See additional red-lined comments in the report. 13. On the same page 9, an orifice calculations for a stage-discharge table is shown. The orifice area used is 0.79 sq. ft. This is equal to a 0.5'' diameter orifice. This orifice size does not match the 1.53"orifice size shown in the modular wetland per the SWMP report and the site plan C-10. Please clarify and show the location of the orifice for 100 year detention. Provide additional detail to clarify which facility is used for 100 year detention. 14 .. Revise the area calculations provided in the attachment 4 to agree with the area calculations provided in the SWMP report and the data provided on the site plan, sheet C-Ol & C-07 (see item 3 above). 15. Revise the drainage map to include the entire disturbed area. Clearly delineate the drainage sub- basins and their exit points. Identify the point of compliance (POC). Address the drainage on the proposed slope. How is the slope drainage controlled? Show a drainage swale at the bottom of the slope to route the drainage to an existing catch basin and avoid impact on the existing structures. 16.

Page4 INTRODUCTION This Water Quality Technical Report (WQTR) is required by the City of Carlsbad for all Development and Redevelopment Projects, pursuant to the City of Carlsbad Storm Water Management and Discharge Control Ordinance (Municipal Code Chap 15.12). The purpose of this WQTR is to address the water quality impacts from the proposed new Dark Ride at Legoland, Carlsbad. The site design, source control and treatment control Best Management Practices (BMPs) will be utilized to provide long term solution to protecting water quality. This WQTR is subject to revisions as needed to accommodate changes to the project design, or as required by the City and/ or Engineer. 2.0 APPLICABILITY AND PROJECT TYPE Based on the criteria set forth in the City's Storm Water Standard Questionnaire (form E-34 from the City website) for New Development and Redevelopment Projects, the proposed project is identified as a Priority Development Project. The proposed project has been identified as a Priority Project; this WQTR includes design and supporting calculations for site design Low Impact Development (LID) BMPs, Source Control BMPs, and Treatment Control BMPs. The final/ signed "City of Carlsbad Storm Water Standards Questionnaire (E-34)" is included as Attachment 1. May 12,2015 Page 5 3.0 PROJECT OVERVIEW 3.1 Project Location The project includes 2lots that are located at Legoland in the City of Carlsbad, California and has an APN of 211-100-09. See Attachment 2 for Vicinity & Site Location maps. See Attachment 2 including an extracted floodplain map from the FEMA website. 3.2 Project Description The proposed site development consists of demolishing existing buildings and building a new ride, gift shop, and a courtyard. 3.3 Project Size The total site property acreage for Legoland is approximately 5,754,712 SF (132.110 acres). The total site property for the new proposed ride is approximately 36,070 SF (0.828 acres). 3.4 Impervious and Pervious Surface areas The existing pervious area the site is approximately 10,488 SF (0.241 acres). The existing impervious area is approximately 25,582 SF (0.587 acres) resulting in an impervious percentage of70.9%. After development, the pervious area will be 2,818 SF (0.065 acres), the pavers area will be 10,900 SF (0.250 acres), and the impervious area will be 33,252 SF (0.763 acres) resulting in an impervious percentage from 70.9% to approximately 92.0%. Although the paver system is pervious by collecting and retaining storm water within its section, the geotechnical report has prohibited any percolation into the ground below improvements. Therefore, the paver section will be lined with impervious liner and thus for the purposes of this report we have counted the pavers as impervious. May 12,2015 Page6 • 4.0 PROJECT SITE ASSESMENT This section includes information used to consider the potential water quality and hydrologic impacts from the proposed project. This information is important when considering the appropriate BMPs to reduce identified potential impacts as well as when designing low impact development (LID), source control, and treatment control measures to reduce water quality impacts. 4.1 Land Use The site currently consists of multiple buildings, an AC roadway, and a concrete pathway. 4.2 Existing Topography and Site Soils The existing project site is currently developed.

Treatment control BMPs target anticipated potential storm water pollutants. The storm water management plan applies these BMPs to the maximum extent possible. 6.1 Site Design and LID Design Strategies and BMPs Site design BMP alternatives are limited to this project given its small infill development. Some of the LID practices that will be incorporated in the design are: 1. Optimizing Site Layout: The site has been designed to minimize grading and preserve existing site features and topography. It is proposed that all runoff be captured in the proposed pervious pavement. 2. All impervious areas will drain either into landscape areas or into the treatment control modular wetlands. 6.2 Source Control BMPs Source control BMPs include permanent, structural features incorporated into the project as well as operational BMPs, good housekeeping practices, which will be implemented by the owner. Source control measures will either reduce the amount of runoff from the site or prevent contact between potential pollutants and storm water. The following source control for a priority development project will be practiced for this project: 1. Use of Efficient Irrigation Systems & Landscape Design: a. Implement rain shutoff devices to prevent irrigation during and after precipitation events in accordance with section 2 E of the City of Carlsbad's Landscape Standards. b. Reduce irrigation contribution to dry-weather runoff by avoiding spray irrigation patterns where overspray to paved surfaces or drain inlets will occur. c. To avoid overwatering and potential irrigation runoff, design irrigation systems to each landscape area's specific water requirement. d. Implement flow reducers or shutoff valves triggered by a pressure drop to control water loss in the event of broken sprinkler heads or lines. e. A void locating drain inlets in lawn areas, since such inlets tend to be sources or irrigation runoff and the transport mechanism for lawn care products. Design the May 12,2015 Page 11 grading and drainage systems such that drain inlets can be located outside of the lawn area, or include a non-turf buffer around the inlet. 2. Design Trash Storage Areas to Reduce Pollution Contribution: a. Trash storage areas shall: Be paved with an impervious surface designed to prevent run-on from adjoining areas and screened or walled to prevent off-site transport of trash. b. Contain attached lids on all trash containers to prevent rainfall intrusion. c. Contain a roof or awning, at the discretion of the City, for high usage trash areas such as those for fast food establishments, convenience stores, and high-density residential developments. 3. Provide Storm Water Conveyance System Stamping and Signage: a. Concrete stamping, or approved equivalent method, shall be provided for all storm water conveyance system inlets and catch basins within the project area. b. Language associated with the stamping (e.g., "No Dumping-I Live in <<name receiving water>>'') must be satisfactory to the City Engineer. Stamping may also be required in Spanish. c. Post signs and prohibitive language (with graphical icons) which prohibit illegal dumping at trailheads, parks, building entrances and public access points along e channels and creeks within the project area. 6.3 Treatment Control BMP For treatment purposes, the proposed project will implement the procedure outlined in Appendix 1 (SUSMP approach). The structural treatment control BMPs will meet the following requirements: • Be designed to remove pollutants to the maximum extent possible based on ratings for pollutant removal efficiency • Meet a minimum criteria of "medium removal efficiency" for the most significant pollutants of concern for the project • Be correctly sized according to numeric sizing requirements • Be implemented close pollutant sources to the extent feasible May 12,2015 Page 12 6.3.1 Structural Treatment BMP Selection According to the Structural Treatment BMP Selection Procedure Section 2.3.3.5 and Notes on Pollutants of Concern Section 2.3.3.7, the most appropriate treatment control that will be implemented in the project will be modular wetlands.

Base Course -within the context of this specification, a washed open graded free draining aggregate material (#57 Stone) of a designed thickness that provides both structural support over the Sub-base and water storage capacity (within the voids). It also serves as a choking material between the Bedding Course and Sub-base. B. Bedding Course -within the context of this specification, a two-inch thick layer of washed open graded free draining aggregate material (#8 Stone) loosely screeded smooth for bedding of the Concrete Pavers. C. Concrete Pavers -within the context of this specification, solid individual paving units manufacturing from concrete that are either specifically designed for use in permeable applications (include joints and voids) or are laid in a pattern that creates large enough openings to provide infiltration. Concrete Pavers are shipped in clusters called bundles or cubes, which consist of several layers of pavers strapped or wrapped together. a. Voids -larger openings between the individual pavers that provide for infiltration. b. Joints -smaller openings between the individual pavers that provide vertical and horizontal interlock between units. D. Edge Restraint-within this specification, a cast in place concrete curb, building or other stationary object that prevents the lateral movement of the Bedding Course and Concrete Pavers so they do not spread and loose interlock. Other Edge Restraints options include plastic, steel or aluminum edging, cut stone, precast concrete and submerged concrete edge complete with mortared pavers. Note: for commercial applications, cast in place concrete Edge Restraints are recommended as they provide the greatest resistance to lateral movement. The other alternatives are listed for informational purposes only. E. Geotextile -Woven or non-woven fabrics made from plastic fibers used primarily for separation between Sub-base and Subgrade. F. Horizontal Drainage Piping-series of horizontal pipes within the sub-base that discharge to a catchbasin, ditch or other receiving body beyond the extent of the paved area. Piping is typically elevated in a Partial Exfiltration System, and at the bottom of the Sub- base in a No Exfiltration System. G. Laying Face -the working edge of the pavement where the laying of pavers is occurring. H. Mechanical Installation -The use of specialized machines to lift whole layers of pavers from the bundles and place them on the prepared bedding course. These specialized machines are designed specifically for this application. I. Membrane Liner - impermeable liner placed at the bottom and sides of a No Exfiltration System, used to prevent the exfiltration/discharge of water other than through the Horizontal Drainage Piping. Usually includes a geotextile on top (possibly bottom) for protection. J. Permeable Joint Material - a washed open graded free draining aggregate material (typically #8, #89 or #9 Stone) used to fill the spaces Goints and voids) between Concrete Pavers to create interlock and still maintain infiltration. K. Permeable Interlocking Concrete Pavement System - a system of paving consisting of Concrete Pavers placed in an interlocking pattern with the joints and voids filled with Permeable Joint Material. The minimum rate of infiltration of the Concrete Pavers and Permeable Jointing Material is 10 inches per hour, or the design storm, whichever is greater. The Bedding Course, Base Course and Sub-base Courses provide structural support over the Subgrade and stores, exfiltrates (into the Subgrade) and/or drains the infiltrating water. L. Sub-base Course -within the context of this specification, an open graded free draining aggregate material (#2 Stone) of a designed thickness that provides both structural support over the Subgrade and water storage capacity (within the voids). M. Subgrade-the soil upon which the pavement structure and shoulders are constructed. 2.02 Concrete Pavers A. Supplied by: B.

NOTE: The pattern in which pavers are installed is very important in vehicular applications. Avoid patterns with long continuous lines; these may be subject to failure under vehicular traffic. NOTE: There are recommended minimum thicknesses, and maximum aspect ratios, of pavers used in different applications (eg: pedestrian, light vehicular, heavy vehicular). To verify what is applicable to the given project, contact your regional Belgard representative or visit our web site at BelgardCommercial.com. C. Concrete Pavers shall conform to the following requirements set forth in ASTM C-936: 1. Measured length or width of test specimens shall not differ by more than +/-0.063 in, while measured thickness shall not differ by more than +/-0.125 in. 2. Average compressive strength of 8,000 psi (55 MPa) with no individual unit under 7,200 psi (50 MPa) when tested in accordance with ASTM C-140. Note: The listed compressive strength results are based on testing protocols for a 2.63 inch (60 mm) thick unit. If thicker pavers are tested, then the resulting compressive strength test results should be multiplying by the applicable adjustment factor. Please refer to ICPI Tech Spec 9 for the adjustment factors. 3. Average absorption of 5% with no unit greater than 7% when tested in accordance with ASTM C-140. 4. Where freeze-thaw testing is required, the average mass loss of all specimens tested shall not be greater than (A) 225 g/m2 when subject to 28 freeze thaw cycles, or (b) 500 g/m2 when subject to 49 freeze thaw cycles. Testing shall be conducted using a 3% saline solution in according to ASTM C-1645. D. Efflorescence shall not be a cause for rejection. Note: Efflorescence is a whitish powder-like deposit that sometimes appears on concrete products. Calcium hydroxide and other water-soluble materials form or are present during the hydration of Portland cement. Pore water becomes saturated with these materials, and diffuses to the surface of the concrete. When this water evaporates, the soluble materials remain as a whitish deposit on the concrete surface. The calcium hydroxide is converted to calcium carbonate during a reaction with carbon dioxide from the atmosphere. The calcium carbonate is difficult to remove with water. However, the efflorescence will wear off with time, and it is advisable to wait a few months before attempting to remove any efflorescence. Commercially available cleaners can be used, provided directions are carefully followed. Some cleaners contain acids that may alter the color of the pavers. E. Pigment in Concrete Pavers shall conform to ASTM C-979. 2.03 Bedding Course A. Clean, non-plastic aggregate, free from deleterious or foreign matter, manufactured from crushed rock. B. Micro Deval Degradation of less than 8% as per ASTM D-6938. C. Percent of angular and sub-angular particles greater than 90%. Do not use rounded river gravel. D.

The Horizontal Drainage Piping shall be perforated or slotted PVC pipe manufactured in accordance with ASTM D-3034, or corrugated HOPE pipe manufactured in accordance with ASTM D-3350. PART 3-EXECUTION 3.01 Inspection Note: Construction drawings and design calculations for the Permeable Interlocking Concrete Pavement System are typically prepared and stamped by a Professional Engineer registered in the state of the project. The engineering designs, techniques, and material evaluations should be completed in accordance with the ICPI Permeable Paver Design Manual, and/or State/County/City Stormwater Regulations (whichever is applicable to designer). However, the Contractor still has an obligation to the Owner to provide a quality product; it is for this reason that the Contractor, being the one most familiar with the site, is required to conduct a Pre-Construction Inspection to ensure that nothing is overlooked. A. Prior to commencement of any work, the Contractor shall conduct a pre-construction meeting with the Owner, Design Engineer and affected sub-trades. The pre-construction meeting should, at a minimum, verify: a. The location of the Mock Up, and whether it will be part of the final construction or need to be removed. b. The site layout conforms to the Site Plan. In particular, the location and elevation of discharge points (if any) of the Horizontal Drainage Pipes. c. The excavation work conforms to the specified lines and elevations. Subgrade shall be trimmed to within 0 and~ in of the specified grades. The surface of the prepared Subgrade shall not deviate by more than 3/8 in from the bottom edge of a 10-foot straight edge laid in any direction. d. The condition of the subgrade, in particular that the surface infiltration (where desired) has not been adversely impacted by the excavation work. Where compaction is desired, that the compaction densities have been met. Note: Compaction of the soil subgrade may be necessary to achieve stability under vehicle load. Compaction, however, will reduce the permeability of soils. In such cases, laboratory and on- site testing for density and soil permeability should be conducted. These can help establish a relationship between compacted density and anticipated design permeability after compaction. An experienced civil or geotechnical engineer familiar with local soil conditions should be consulted for determining project standards for the percentage of soil Proctor density and test methods for permeability. When soil compaction is required, standard Proctor density per ASTM D-698 for pedestrian areas and residential driveways is recommended. Modified Proctor density per ASTM D-1557 is recommended for areas subject to heavy vehicular traffic. Density and moisture should be checked in the field with a nuclear density gauge or other test methods for compliance to specifications. e. Locations of curbs, grade beams, utility structures, light standards, tree wells or any other protrusions as applicable to the project. f. The details of the site's 'Erosion and Sediment Control Plan'. g. Panel Installation Drawings for the Geosynthetics, in particular the location of any protrusions through the Membrane Liner where boots are required. B. Although the Owner may provide soil testing and quality assurance inspection during earthwork and Subgrade preparation, the Owner's quality assurance program does not relieve the Contractor of responsibility for quality control and system performance. Contractor shall obtain any quality control testing or inspection not provided by the Owner that is necessary to satisfy the Contractor with the condition of the Subgrade prior to commencement of the work. This may include: a. Proof rolling of the subgrade to determine presence of soft spots or localized pockets of objectionable materials. b. Infiltration testing to verify the subgrade has not been adversely impacted. c. Compaction testing. C. Where deficiencies or inconsistencies are identified, the Contractor shall notify the Design Engineer in writing. The Contractor will not proceed with the work until the Design Engineer has verified that the deficiencies or inconsistencies have been addressed. D. Beginning of Installation means acceptance of Subgrade. 3.02 Installation Base Course A. Keep area where pavement is to be constructed free from sediment during the entire job. Any materials contaminated with sediment shall be removed and replaced with clean material. B. Install Membrane Liner in accordance with the manufacturer's recommendations. The Membrane Liner is applied to the bottom and sides of the excavation. Allow for enough Membrane Liner to exceed the final elevation of the surface. After completion of the surface, the excess liner should be cut flush with the finished grade, Note: Where required, the Membrane Liner is place on the prepared soil subgrade as a containment (impermeable) material. Sections are welded together, and boots are installed around all protrusions. C. Install Geotextiles as required in accordance with the specifications and drawings. The Geotextile is applied to the bottom and sides of the excavation with overlapping joints a minimum of 12 inches. Overlaps to follow down slope. Allow for enough geotextile to exceed the final elevation of the surface. After completion of the surface, the excess geotextile should be cut flush with the finished grade, Note: Where required, Geotextile is placed on the prepared soil subgrade as a separation material. Overlap is a function of CBR: 12 to 18 inches for CBR of 3 and above; 24 to 36 inches for CBR of 1.0 to 3.0; or, sewn for CBR less than 1.0. Please consult manufacturers' specifications and the Geotechnical Engineer. D. Install the Sub-base Course and Base Course at the thicknesses, compaction rates, surface tolerances, and elevations outlined in the specifications. 1. Place and spread the first layer of Sub-base without displacing or damaging the geosynthetics (if used). To prevent damage, tracked vehicles must not be used to spread the initial Sub-base layer. 2. The aggregate should be spread and compacted in uniform layers not exceeding 6 inch loose thickness. Compaction is performed using either a 10 T (10 ton) vibratory roller or a minimum 13,500 lbf centrifugal force reversible vibratory plate compactor. For each lift, make at least two passes in the vibratory mode and at least two passes in the static mode -continue compaction until there is visible movement in the materials. 3. At the specified elevation(s), install the Horizontal Drain Pipes in accordance with the manufacturer's recommendations. Ensure the Pipes are properly sloped to provide proper drainage to the outlets Pipes shall be surrounded by a minimum of 3 inches of Base Course material to prevent damage from the Sub-base material. Care must be taken not to damage Horizontal Drain Pipes during subsequent aggregate installation. Note: the Horizontal Drain Pipes are surrounded by the #57 stone (Base Material) as the larger sized pieced within the #2 Stone Sub-base Material) can perforate the plastic pipe. 4. Final surface tolerance should be plus or minus 1 inch over a 10 foot straight edge laid in any direction. 5. Attention will be paid to providing proper compaction near curbs, grade beams, concrete collars around utility structures, lights standards, tree wells, building edges and other protrusions as applicable to the project. In areas not accessible to large compaction equipment, compact to specified density with mechanical tampers Oumping jacks). E. Before commencing the placing of the Bedding Course, the base shall be inspected by the Owner or the Consultant 3.03 Installation Edge Restraints A. Adequate edge restraint shall be provided along the perimeter of all paving as specified. The face of the edge restraint, where it abuts pavers, shall be vertical. B. All concrete edge restraints shall be constructed to dimensions and level specified and shall be supported on a compacted Base not less than 6 inch thick. C. Concrete used for the construction of edge restraints shall be air-entrained and have a compressive strength as specified. All concrete shall be in accordance with ASTM C94 requirements. 3.04 Installation Bedding Course, Concrete Pavers and Permeable Joint Material A. Spread the Bedding Course evenly over the Base Course and screed to a nominal 2 in. thickness. Do not use the bedding material to fill depressions in the Base Course surface. B. The Contractor shall screed the Bedding Course using either an approved mechanical spreader (e.g.: an asphalt paver) or by the use of screed rails and boards. C. Surface tolerances shall be 3/8 inch over a 1 0-foot straight edge. D. Loose screed the bedding course. E. Ensure that Concrete Pavers are free of foreign material before installation. Concrete Pavers shall be inspected for color distribution and all chipped, damaged or discolored Concrete Pavers shall be replaced. Initiation of Concrete Paver placement shall be deemed to represent acceptance of the pavers. F. Lay the Concrete Pavers in the pattern(s) as shown on the drawings. Maintain straight pattern lines. G. Paving units shall be installed from a minimum of 3 bundles for hand installations, 6 bundles for mechanical installations, simultaneously to ensure color blending. Note: Color variation occurs with all concrete products. This phenomenon is influenced by a variety of factors, e.g. moisture content, curing conditions, different aggregates and, most commonly, from different production runs. By installing from a minimum of three bundles simultaneously, variation in color is dispersed and blended throughout the project. H. Joints between the individual Concrete Pavers shall be maintained according to the spacer bars. I. Fill gaps at the edges of the paved area with cut pavers or edge units. Do not install cut pavers smaller than one-third of a whole paver along edges subject to vehicular traffic - trim two pavers to fit. J. Cut pavers using a masonry saw. Upon completion of cutting, the area must be swept clean of all debris to facilitate inspection and to ensure the Concrete Pavers are not damaged during compaction. K. Using a low amplitude plate compactor capable of at least 5,000 lbs. (22 kN) compaction at a frequency of 75hz-100hz, compact and seat the Concrete Pavers into the Bedding Course. L. The pavers shall be compacted to achieve consolidation of the Bedding Course and brought to level and profile by not less than three passes. Initial compaction should proceed as closely as possible following the installation of the paving units and prior to the acceptance of any traffic or application of Permeable Joint Material. M. Any units that are structurally damaged during compaction shall be immediately removed and replaced. N. Apply a dressing of Permeable Joint Material to the surface and sweep into the joints and voids. Fill joints and voids, then sweep off excess material before vibrating the material down into the joints using a plate compactor. This will require at least two or three passes with the compactor. 0. Do not compact within 6 feet of the unrestrained edges of the paving units. P. All work to within 3ft (1 m) of the laying face must be left fully compacted at the end of each day. Cover the laying face with plastic sheets overnight if not closed with cut and compacted pavers. Q. Sweep off excess aggregate when the job is complete. 3.05 Quality Assurance/Quality Control A. Quality Assurance -The Owner may engage inspection and testing services, including independent laboratories, to provide quality assurance and testing services during construction. This does not relieve the Contractor from securing the necessary construction quality control testing. B. Quality assurance should include as a minimum verification with the Design Engineer that the Contractor's quality control plan and testing are adequate. Quality assurance shall also include observation of construction for general compliance with design drawings and project specifications. C. Quality Control -The Contractor shall engage inspection and testing services to perform the minimum quality control testing described in the design plans and specifications. Only qualified and experienced technicians and engineers shall perform testing and inspection services. D. Quality control testing shall include backfill testing to verify soil types and compaction, and verification that the system is being constructed in accordance with the design plans and project specifications. 3.06 As-built Construction Tolerances A. Final inspection shall be conducted to verify conformance to the drawings after removal of excess aggregate. All pavements shall be finished to lines and levels to ensure positive drainage at all drainage outlets and channels. B. The final surface elevations shall not deviate more than +/-3/8 inch under a 10 ft long straight edge. Note: For installation on a compacted aggregate base and soil subgrade, the specifier should be aware that the top surface of the pavers may be 1 /8 to 1 /4 in. (3 to 6 mm) above the final elevations after compaction. This difference in initial and final elevation is to compensate for possible minor settling. 3.07 Limited Warranty A. Manufacturer to provide customized Commercial Limited Warranty directly to property owner, general contractor, specifying architect, specifying engineer and installer for project covering the interlocking concrete pavers against chipping, breaking, splitting and other manufacturing defects as well as the labor required to reinstall them should they be deemed defective. B. Commercial Limited Warranty is voided unless product is installed by a Belgard Authorized Commercial Contractor and endorsed in writing by manufacturer's authorized representative. C. Warranty must have original signature from authorized manufacturer's representative and be delivered to all appropriate parties upon purchase order for the entire project.

The project site is located at 1 Legoland Drive in Carlsbad. The project area is approximately 37,290 SF. The property currently consists of multiple buildings, an AC roadway, and a concrete pathway. The proposed site development consists of removing the existing buildings, AC road, and concrete walkway and preparing the site for the construction of a new ride and pervious pavement. Incidental underground utilities, hardscape, site landscaping, vehicular pavement, and porous pavement are also proposed with this development. The area is industrial and site elevations range from approximately 159 to 151 feet above mean sea level (msl). See attachment 1 for the Site Location and Vicinity Maps. Although the paver system is pervious by collecting and retaining storm water within its section, the geotechnical report has prohibited any percolation into the ground below improvements. Therefore, the paver section will be lined with impervious liner and thus for the purposes of this report we have counted the pavers as impervious. DESIGN CRITERIA AND ASSUMPTIONS 1. The site soil classification as hydrologic soil type D. See Attachment 2. 2. Per the San Diego County Hydrology Manual (2003) Rainfall Isopluvial Map (See Attachment 2): • 100 Year Rainfall Event-6 hours P6 = 2.60 inches/hour • 100 Year Rainfall Event-24 hours P24 = 4.50 inches/hour 3. Per the San Diego County Hydrology Manual (2003) Table 3.1: 4. Hydrologic calculations were performed using the CIVILCAD/CIVILDESIGN Engineering software version 7.6 per methods as outlined within the San Diego Hydrology Manual (2003). The hydrology calculations for proposed and existing conditions may be found within the hydrology calculations section of this report. Page 1 6-11-15 EXISTING CONDITIONS DISCUSSION Drainage Study Legoland Dark Ride Carlsbad, CA The site is a developed industrial lot and comprises of two hydrologic basins. The basin sheet flows and drains directly to a concrete walkway and AC roadway. Below is a summary of pre-development criteria for the subject property: TABLE 1:100 YEAR PRE-DEVELOPMENT CRITERIA Tc Area Node c (Min.)
