The easterly portion of Robertson Ranch is named the East Village. The East Village is immediately north of the Rancho Carlsbad Mobile Home Park (RCMHP) and west of College Boulevard. Cannon Road follows an east-west alignment near the southerly boundary of the East Village. The area north of Cannon Road is the main development area, and will be developed with single- and multi-family residential units. The area south of Cannon Road (Planning Area 22) will contain an approximately 4.4 acre pad developed with residential units. Finally, a park site and 5:1 slope grading (for a wildlife corridor) will be constructed within a portion of Robertson Ranch West Village, which is just west of the East Village, north of Cannon Road, and east of El Camino Real. CITY OF OCEANSIDF. HIGHWAY SITE OF VISTA fl m * CITY OF SAN MARCOS CITY OF ENdNITAS Figure 1. Vicinity Map Calavera Creek currently flows along the easterly then southerly portions of the proposed Robertson Ranch project. The relevant Flood Insurance Rate Maps (FIRM Number 06073C0766 F and 06073C0768 F)) are included in Figures 2 and 3, which are located after this report text. FIRM 06073C0768 F shows that an existing floodwall is located within a portion of Calavera Creek. The wall is generally aligned along the direction of flow. The main channel of the creek is south of the wall, while the area north of the wall is an overbank area subject to inundation under pre-project conditions. The RCMHP is south of the wall (and south of the main channel) and north of El Camino Real. Figure 4 contains a photograph taken in the downstream direction of the Calavera Creek main channel within RCMHP. RCMHP is on the left side of the photograph and the wall is on the right. The FIRM indicates that the 100-year water surface elevations are not equal on opposite sides of the wall. The FIRM also shows that the main channel of Calavera Creek confluences with Agua Hedionda Creek near the west end of RCMHP. This Conditional Letter of Map Revision revises the entire reach of Calavera Creek from Agua Hedionda Creek to the upstream FIRM limits due to improvements by Robertson Ranch and/or its developer (some of the improvements modeled in this CLOMR are not specifically part of the Robertson Ranch project, but are next to the site and by the same developer. This CLOMR includes all of the related projects within and adjacent to Robertson Ranch). CLOMR IMPROVEMENTS The improvements included in this CLOMR are intended to remove the Robertson Ranch development from the Calavera Creek floodplain and floodway and reduce the floodplain limits within the RCHMP. This is accomplished by reducing the 100-year flow rate through detention and also by constructing underground drainage facilities to convey some of the creek flow. The HEC-RAS Work Map in the map pocket provides an overview of the improvements. The upstream most improvement is Detention Basin BJB, which is a flow-by (only higher flows enter the basin) detention basin located immediately north of the intersection of Cannon Road and College Boulevard. Calavera Creek flows entirely into Detention BJB. The flow in Detention Basin BJB will primarily outlet near the southerly end of the basin in an 1 1-foot wide by 7-foot high reinforced concrete box (RGB) culvert. A wall will be constructed within the 1 1-foot by 7-foot RCB approximately 350 feet below the upper end of the RCB. The wall will split the flow in the RCB in two directions. A portion of the flow will be directed into an 84-inch reinforced concrete pipe (RCP) aligned westerly in Cannon Road and the remainder will continue south in the 1 1-foot by 7-foot RCB. The flow in the 84-inch pipe will ultimately be conveyed to a low lying area on the west end of Robertson Ranch (near the park site and habitat corridor) north of the intersection of El Camino Real and Cannon Road. The 100-year flow will pond in this area before exiting southwesterly through an existing 8-foot by 8-foot RCB under El Camino Real and ultimately confluencing with Agua Hedionda Creek. The flow remaining in the 1 1-foot by 7-foot RCB below the flow split wall will continue to the Calavera Creek main channel, which is along the northern portion of RCMHP. The flow will then be conveyed southwesterly in the main channel and ultimately confluence with Agua •*« Hedionda Creek. A weir exists in the floodwall along the north side of the main channel (see Figure 5). The weir allows flow to be conveyed through the floodwall and into the main channel. The weir has a triangular cross-section. The weir will be widened to a rectangular cross-section « to better convey flow through the floodwall. The engineering plans for Detention Basin BJB and its 11-foot by 7-foot RGB outlet, the flow _ divider wall in the RGB, the 84-inch RCP and Cannon Road, the weir modification, and the park and habitat corridor grading are included in the appendices. Each appendix contains engineering *" analyses for the CLOMR and the related plans. ~ ENGINEERING ANALYSES Several engineering analyses were performed to analyze the 100-year floodplain and floodway "* associated with the proposed improvements. Since the Flood Insurance Study only includes a 100-year analysis for Calavera Creek, this CLOMR only includes 100-year analyses. The analyses are described below and electronic files are included on the CD at the back of this "• report. HEC-1 Analysis *• An updated 100-year hydrologic analysis for the Calavera Creek watershed was performed using HEC-1. The watershed was originally delineated by Rick Engineering Company (under contract m with the city of Carlsbad) using the United States Geological Survey's quadrangle maps (see the tH HEC-1 Workmap in Appendix A). Rick performed field investigations to verify the watershed boundaries. The HEC-1 Work Map also includes the Agua Hedionda Creek watershed; however, ^ this CLOMR and the HEC-1 analysis is only for the Calavera Creek watershed (Drainage Basins Hi C1-C4, RCC, RRC2 and RRCH). Furthermore, the work map shows a Basin BJ in the Calavera Creek watershed. This is a future project that has not been designed, and is not part of thism CLOMR.m In order to model this CLOMR's improvements, Rick's HEC-1 analysis was modified based on m the attenuation at Detention Basin BJB, the flow split within the 11-foot by 7-foot RGB, and the g| ponding that will occur in the low lying area at the outlet of the 84-inch RCP. The current conditions at Lake Calavera (current dam and spillway) are included in the model. The HEC-1 m analysis and support material is included in Appendix A. The Detention Basin BJB, park site, ^f and habitat corridor grading plans are also included in Appendix A. The park site and habitat corridor grading affect the ponding characteristics of the low lying area. Table 1 summarizes the «• relevant results from the HEC-1. m m Location Upstream of Detention Basin BJB Exiting Detention Basin BJB Entering 84" RCP below Split Continuing in 1 1 'x 17' RGB below Split Calavera Creek at Confluence with Agua Hedionda Creek Exiting 84" RCP Low Lying Area at 84" RCP Outlet Entering 8'x8' RCB under El Camino Real 100- Year Flow Rate, cfs 1,501 971 473 498 909 497 545 Ponded Water Surface Elevation, feet MSL 76.4 35.3 Table 1. 100-Year HEC-RAS Flow Rates The post-project floodplain within Detention Basin BJB is based on the ponded water surface elevation from the HEC-1 results rather than a hydraulic analysis since the ponding will govern. Furthermore, under post-project conditions, a floodway is not delineated within Detention Basin BJB or its 11-foot by 7-foot RCB outlet because these will be permanent drainage control facilities. 84-Inch RCP Analysis A 100-year WSPGW hydraulic analysis was performed to determine the hydraulic grade line in the 84-inch RCP. The analysis was based on storm drain plans by O'Day Consultants. There is a segment between WSPGW Stations 19+51.18 and 20+37.34 where the pipe transitions to a 10- foot wide by 4-foot high box culvert to accommodate utility crossings. From the HEC-1 results in Table 1, the flow rate in the pipe increases from 473 cfs at the upper end to 497 cfs at the lower end. The WSPGW results and storm drain plans are included in Appendix B, and show that open channel flow will exist in the lower portions of the pipe (below WSPGW Station 19+46.18). Pressure flow occurs above this station, but the hydraulic grade line does not rise above the ground surface. Therefore, the post-project floodplain has been delineated as being contained in the pipe. Calavera Creek Main Channel Analysis A HEC-RAS analysis was performed for the main channel of Calavera Creek in order to establish an updated floodplain and floodway. Improvements are not proposed in the main channel. However, the Robertson Ranch improvements will affect the main channel because the improvements will lower the 100-year flow rate. The HEC-RAS input is as follows. The post-project HEC-RAS cross-sections (5.11 to 3410) are generally in the same location as the cross-sections in FEMA's effective model. The following relates the HEC-RAS cross-section numbers to the letter designations on the FIRM: 5.11 is A, 400 is B, 580 is C, 1000 is D, 1230 is E, 1470 is F, 1810 is G, 2100 is H, 2420 is I, and 2700 is J. The cross-sections were created using topographic mapping from May 12, 2005. The cross- sections were encroached along the floodwall on the right overbank and the mobile homes along the left overbank to properly model the effective flow area, but the floodplain delineation assumed the wall did not act as a levee. Since Calavera Creek confluences with Agua Hedionda Creek (Agua Hedionda Creek is a much larger watercourse), the starting water surface elevations were based on the floodplain (44.0 feet) and floodway elevations (44.7 feet) at the confluence from the Flood Insurance Study. This will ensure a proper tie-in at the downstream study limit and account for the 100-year backwater from Aqua Hedionda Creek. A roughness coefficient of 0.05 for the channel and overbanks was selected based on a field investigation. The 100-year flow rate was obtained from the HEC-1 analysis in this CLOMR and varies from 629 to 909 cfs. The HEC-RAS results are included in Appendix C and the revised floodplain and floodway are delineated on the HEC-RAS Work Map in the map pocket at the back of this report. Flow Split Analysis Two separate HEC-RAS analyses were performed to analyze the flow split caused by the wall within the 11-foot by 7-foot RGB. A portion of the flow will be directed into the 84-inch RCP and a portion will continue downstream in the 11-foot by 7-foot RCB. Therefore, a HEC-RAS analysis was created starting in the 84-inch RCP, continuing upstream to the split, and ending at the upper end of the 11-foot by 7-foot RCB (HEC-RAS cross-sections 0.1 to 9). The starting water surface elevation was obtained from the 84-inch RCP WSPGW analysis. A lid was added to the cross-sections to model the closed conduits and cross-section interpolation was performed to increase the number of cross-sections. A second HEC-RAS analysis started at the weir (based on the proposed weir modification) near the Calavera Creek main channel then extended up the entire length of the 11-foot by 7-foot RCB (HEC-RAS cross-sections 1 to 9), which included the flow split wall. The starting water surface elevation was obtained from the Calavera Creek HEC-RAS analysis. The cross-sections upstream of the wall are the same in both HEC-RAS analyses. An iterative procedure was used to determine how the 971 cfs approaching the split would be divided between the 84-inch RCP and the 11-foot by 7-foot RCB. In both HEC-RAS analyses, the wall that splits the flow is located between cross-sections 5 and 6. Cross-section 7 is just upstream of cross-section 6 and the wall. The individual flow rates in the RCB and RCP below the split must add up to 971 cfs since this is the flow rate approaching the split. Therefore, the total flow rate below the split was maintained at 971 cfs, but the individual flow rates were varied in the RCB and RCP until the hydraulic grade lines above the split (above cross-section 7) matched in each analysis. This procedure determined that approximately 473 cfs will be directed to the 84-inch RCP and 498 cfs will continue in the 11-foot by 7-foot RCB. The HEC-RAS analyses are included in Appendix D along with the plans for the flow split wall, 11-foot by 7-foot RCB, and weir modification. The analyses show that the 100-year flows will be contained in the 11-foot by 7-foot RCB and upper portion of the 84-inch RCP. Therefore, the post-project floodplain is shown as being contained in the drainage facilities. CONCLUSION This Conditional Letter of Map Revision for Robertson Ranch includes updated hydrologic and hydraulic analyses for Calavera Creek. The project proposes a rather intricate system including detention, a flow split, and culverts/pipes. This system will protect the project from flood inundation and reduce the floodplain along the Rancho Carlsbad Mobile Home Park. An Annotated FIRM showing the post-project floodplain and floodway is included in Figure 6. The entire Calavera Creek floodplain and floodway will be modified by the project. The pre-project Calavera Creek floodplain and floodway on the Annotated FIRM have been screened into the background. The downstream portion of the post-project floodplain and floodway tie into the Agua Hedionda Creek floodplain and floodway. The upstream ends of the detailed study end at the same location as the effective study. The Annotated FIRM indicates where the 100-year flows will be contained in culverts and pipes. The required CLOMR forms are included after the figures.

Pre-Submittal Review of Hydraulic Models DHS-FEMA has developed two review programs, CHECK-2 and CHECK-RAS, to aid in the review of HEC-2 and HEC-RAS hydraulic models, respectively. These review programs verify that the hydraulic estimates and assumptions in the model data are in accordance with NFIP requirements, and that the data are comparable with the assumptions and limitations of HEC-2/HEC-RAS. CHECK-2 and CHECK-RAS identify areas of potential error or concern. These tools do not replace engineering judgment. CHECK-2 and CHECK-RAS can be downloaded from http://wvyw.fema.gov/fhm/frm_soft.shtm. We recommend that you review your HEC-2 and HEC-RAS models with CHECK-2 and CHECK-RAS. If you disagree with a message, please attach an explanation of why the message is not valid in this case. Review of your submittal and resolution of valid modeling discrepancies will result in reduced review time. 4. HEC-2/HEC-RAS models reviewed with CHECK-2/CHECK-RAS?
