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, which has been graded and will be developed with single-and multi-family residential units. The area south of Cannon Road (Planning Area 22) has been graded with an approximately 4.4 acre pad that will be developed with residential units. Finally, a park site and 5: 1 slope grading (for a wildlife corridor) have been completed 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 NOT TO SCALE PACIFIC OCEAN ~ : CITY OF 14STA lr·· CITY OF ENCINITAS Figure 1. Vicinity Map 1 l l I I I I I I I I I I I I I I I I I Calavera Creek currently flows along the easterly then southerly portions of the 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. A Conditional Letter of Map Revision (Case No. 07-09-1313R) was issued for Robertson Ranch by the Federal Emergency Management Agency (FEMA) on October 29,2007 (see Attachment 1 for FEMA's CLOMR approval letter and a copy of the original CLOMR report submittal). The CLOMR proposed revisions to the entire reach of Calavera Creek from Agua Hedionda Creek to the upstream FIRM limits due to improvements within and adjacent to Robertson Ranch. The CLOMR improvements are as follows: 1. 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 through an II-foot wide by 7-foot high reinforced concrete box (RCB) culvert. 2. A wall will be constructed within the 11-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 11- foot by 7-foot RCB. 3. The 84-inch RCP will be constructed to convey flow to a low lying area on the west end of Robertson Ranch (near the park site and habitat corridor) north of the intersection eifEl Camino Real and Cannon Road. The IOO-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. 4. The flow remaining in the II-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. The floodwall was constructed many years prior (circa 1969) to the Robertson Ranch development and is not owned or managed by Robertson Ranch. 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 grading and improvements resulting in the floodplain and floodway modifications proposed by the CLOMR have been constructed and as-built. As a result, this Letter of Map Revision has been prepared to obtain FEMA's final approval for the floodplain and floodway changes proposed by the Robertson Ranch CLOMR. The as-built engineering plans representing the constructed conditions for Detention Basin BJB and its II-foot by 7-foot RCB outlet, the flow divider wall in the RCB, the 84-inch RCP and Cannon Road, the weir modification, the Planning Area 22 grading, and the park and habitat corridor grading are included in the map pocket at the back of this report. 2 I I I I I I I I I I I I I I I I I I I The as-built conditions match the original design plans included in the CLOMR except for the weir wall removal. The original plans proposed a 34-foot wide weir wall opening with a flow line elevation of 52.1 feet. The as-built plans show that the opening is 26.6 feet wide with a flow line elevation of 52.5 feet. The HEC-RAS analysis containing the weir wall was modified to reflect the as-built conditions (see Attachment 2). This modification caused a very minor change from the CLOMR results. The original weir wall analysis is included in Appendix D of the CLOMR, which is provided in Attachment 1 -the weir wall is at cross-section 1 in the "Box Culvert" HEC-RAS plan. The water surface elevation in the two HEC-RAS cross-sections upstream of the weir wall (cross-sections 2 and 3) increase by 0.1 feet under the as-built conditions as compared to the CLOMR. None of the other engineering analyses in the CLOMR needed to be changed. CLOMR CONDITIONS This LOMR contains updated forms, engineering analyses, and mapping to reflect the as-built conditions. There are no changes from the CLOMR except for the minor revision associated with the weir wall. The CLOMR letter contains several conditions that must be met by this LOMR. The following summarizes each condition in italics followed by a discussion of how each c;ondition is met: • Provide evidence that your community has, prior to approval of the proposed ffloodway J encroachment, adopted floodplain management ordinances that incorporate the increased BFEs and revised floodway boundary delineations to reflect post-project conditions, as stated in Paragraph 65.12(b). The city of Carlsbad's Zoning Ordinance contains "Floodplain Management Regulations." Section 21.110.070 of the regulations state that "The areas of special flood hazard identified by the ... Federal Emergency Management Agency (FEMA) in the San Diego County and incorporated areas Flood Insurance Study . . . and all subsequent amendments andlor revisions are herein adopted by reference and declared to be part of this chapter." • Detailed application and certification forms, which were used in processing this required must be used for requesting final revisions to the maps. Therefore, when the map revision request for the area covered by this letter is submitted, Form 1, entitled "Overview & Concurrence Form," must be included Form 1 has been included after the figures following the report text. • Detailed application and certification forms listed below [Forms 2 and 3J may be required if as-built conditions differ from the preliminary plans. The as-built conditions are the same as the CLOMR plans except for the weir wall modification. The weir wall modification does not impact the data on Forms 2 and 3. 3 I I I I I I I I I I I I I I I II I I I However, the current versions of Forms 2 and 3 have been included after Form 1 because the forms have been modified by FEMA since CLOMR was approved. • The current fee for this map revision is $4,800 and must be received before we can begin processing the request. A check for $4,800 has been submitted to cover the LOMR processing. • As-built plans, certified by a registered profession engineer, of all proposed project elements. As-built plans have been provided by either O'Day Consultants or Project Design Consultants for the proposed project elements. The as-built plans are included in the map pocket at the back of this report. These are essentially the same set of plans that were provided in the CLOMR, but now contain an as-built certification. Note that for Detention Basin BJB, the plans that are included contain aerial topography flown after Detention Basin BJB was graded. These plans are not stamped as as-built, but the only information used from these plans was the aerial topography, which reflects the as-built basin grading. • Community acknowledgment of the map revision request. The community acknowledgment has been provided on Form 1. • A copy of the public notice distributed by your community stating its intent to revise the regulatory floodway, or a statement by your community that it has notified all affected property owners and affected adjacent jurisdictions. The city of Carlsbad will publish a public notice in the local newspaper stating its intent to revise the regulatory floodway. A copy of the public notice that will be published is included in Attachment 3. • An officially adopted maintenance and operation plan for the proposed detention basin. This plan, which may be in the form of a written statement from the community Chief Executive Officer, an ordinance, or other legislation, must describe the nature of the maintenance activities, the frequency with which they will be performed, and the title of the local community offiCial who will be responsible for ensuring the maintenance activities are accomplished. The maintenance and operations plan is included in Attachment 3. CONCLUSION A Conditional Letter of Map Revision (Case No. 07-09-1313R) was issued for Robertson Ranch by the Federal Emergency Management Agency (FEMA) on October 29,2007. The grading and 4 I I I I I I I I I I I I I I I I I I I improvements associated with the CLOMR have been completed and as-built. As a result, this LOMR is being submitted to request a revision to the FIRM and FIS. The as-built condition matches the original design plans except for a slight change to the weir wall modification during construction. The hydraulic analysis containing the weir wall modification and associated mapping have been adjusted based on the change and are included on the CD in the map pocket. This is the only engineering analysis that changed from the CLOMR submittaL The effective and duplicate effective hydraulic analyses as well as the final post-project hydrologic, hydraulic, and work map files are also included in the CD. A HEC-RAS Work Map in included in the map pocket. The conditions required in the CLOMR letter have been addressed. An Annotated FIRM showing the post-project floodplain and floodway is included in the map pocket. The entire Calavera Creek floodplain and floodway delineated on the FIRMs have been 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 LOMR forms are included after the figures. 5 • I I I I I I I I I I I I I I I I I I ~ ON THIS PANEL IS LOCATED WITHIN RANGE 4 WEST AND TOWNSHIP 12 SOUTH, JOINS PANEL 0768 I I ZONE X Calavera Creek ___ , Split Flow !-----(!n.lfl.llp.rrr.

"Bud" Lewis Mayor, City of Carlsbad 1200 Carlsbad Village Drive Carlsbad, CA 92008 Dear Mayor Lewis: OCT 292007 IN REPLY REFER TO: Case No.: 07~9:..1313R Community! City ofOarlsbad, CA Community No.: 06028~ 104 This responds to a request that the Department of Homeland Security's Federal Emerg~mcy Manag~ment Agency (FEMA) comment on the effects that a proposed project would have on the efiectiyeFlood Insurance Rate Map (FIRM), and Flood Insurance Study (Frs) report fot San Diego' County, 'Califomia and Incorporated Areas (the effective FIDM and FIS report fot your community). in accordance with »art 6$:of the National Flood Insurance Program (NFIP) regulations. In a ,letter dated May 22, 2007, Mr. Wayne W. Chang, P.E., Chang Consultants, requested that FEMA evaillate the effec~ that the Robertson Ranch residential subdivision (proposed project), detailed hydrologic and hydraulic analyses, and updated ropographic information along Calavera Creek and Calavera Creek Split Flow would;haveon the flood hazard infonnation shown on the effective FIRM and FIS report. The proposed ~ea of revil$ion along Calavera Creek will extend from just upstream ofEl Camino RenIto approximately 4.100 feet upstream. The efiective Special Flood Hazard Area (SFHA). the area that would be inundated by base (l-percent-annual-chance) flood, for the proposed area of revision along Calavera Greek is designated Zone AE with Base Flood,Elevations (BFEs) detennined. BFEs are based on two floodwalL condition analyses: with (perimeter wall iu place) and without (perimeter wall removed). BFEs detem,tined for Calavera Creek on the north side are based on flood wall conditions without the perillieter wall; and BFEs on the sontlt side represent flood wall conditions with the perimet~r wall in place. The proposed project includes placement of fil1~ construction of a new detention, basin" an IJ-foot QY 7 .. :footreinfbrced-concrete box culvert (outlet culvert), an 84-inch reinforced-concretepipe di,veJ,"Sion culvert along Cannon Road (diversion culvert); and a split wall The detention basin is located approximately 4,400 feet upstream of the confluence of Calavera Creek with Agua HediQnda Creek (confluence). Flowing entirely into the detention basin, Calavera.Creek will exit pr:iIrupjly near the southerly end of the basin into the outlet culvert. The outlet culvert is located fromapproxlmately 3,400 feet upstream to approximately 3,900 feet upstream of the confluence. The waU.located approximately 350 feet below the upper end of the outlet culvert, splits the flow into two clirections, A portion of the flow will be directed to the diversion culvert and the remainder will continue to flow through the outlet culvert into the existing Calavera Creek channel. The existing channel ofCalavera Creek extends fromjust upstream to approximately 3,500 feet upstream of the confluence. The diver:sion Gulv¢rt is located north of the existing Calavera Creek and runs from the split wall to a low lying area. resulting in a ponding area approximately 1,000 feet northwest of the confluence. . I I I I I I I I I I I I I I I I I I I 2 All data required to complete our review of this request for a Conditional ~tter of Map Revis~o~ (CLOMR) were submitted with letters from Mr. Chang. We reviewed the submitted data and the data used to prepare the effectiveFIRMf6ryourcommunity,atJ.d determined that the proposed project meets the minimum floodpla,ill man,agement crit¢a Qn:lle NFLP. The submitted existiQ.g conditions HEe-RAS hydraulic compute1,"IDodel, dated October 16, 200,1. was usw as the base conditions model in our review of the proposed conditions model for this CLOMR request. We believe that, if the proposed project is constructed as shown on the certified submitted plans eIititl~d "StonnDrain Plans," prepared by O'Day Consultants, and the data listed below are-received) tbe floodplain boundaries of the base flood will be delineated as shown on the topographic work map entitled '·Calavera CreekHEC-RAS Work Map," certified by Mr. Chang, dated July 23, 2007, arevisioIito the FIRM would be warranted. The submitted HEC-l hydrologic model was used to revise the effective :FIS discharges and to inclUde a split flow location within the culvert. The existing conditions disch~ges at appro~tely 3,300 feet llPst:ream of the confluence are 1,350 cubic feet per second (cfS). The'revised discharge eXiting the detention basin and entering the outlet culvert is 970 efs. A discharge of 475 cfs is diverted ~to the diverSion culvert. As a result of the proposed project and updated topographic infOlU1ation, the BFEs on the'north side of the Hoadwall will be removed. The BFEs on the south side will decrease throughout the revised, reach of Calavera Creek compared to the existing BPEs. The maximum decrease in BFEI 2.4 feet, will occur approximately 3,400 feet upstream of the confluence. As a result of the updated topographic information and proposed project, the SFHA will decrease compared to the effective SFHA. The maxinll,lID deqrease in SFHA width, approximately ~OO feet;.. will oocur approx:imately 800 feet upstream of the confluence. Iil addition, as a result of the proposed Ptoj~ct, the base flood will be contamed in the proposed detention basin, outlet culvert, diverSion culvert, and existing channel from approximately 1,200 feet upstream to approximately 3,500 feet l.lpSfream of the confluence. Also, as a result of the proposed project, the entire reach of Calaveta Creek Split Flow will'be removed. As a result of the proposed project and updated topographic infornation, the width of the ~gulatoty flood way will decrease throughout the revised reach of Calavera Creek compared to the,effective floodway width. The maximum decrease in flood way width, approximately 75 feet, will occur approximately 2,100 feet upstream of the confluence. The floodwaywill be contained in the existing channel of Calavera Creek. In addition, as a result of the proposed project, the effective floodway will be removed from approx:imately 3,300 feet upstream to approximately 4,600 feetupst:ream of the confluenc~.

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 NOT TO SCALE PACIFIC OCEAN CITY OF ENCINITAS Figure 1. Vicinity Map 1 I I I I I I I I I I I I I I I I I 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 E1 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 IOO-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). CLOMRIMPROVEMENTS 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 IOO"-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 II-foot wide by 7-foot high reinforced concrete box (RCB) culvert. A wall will be constructed within the II-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 II-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 E1 Camino Real and ultimatelyconfluencing with Agua Hedionda Creek. The flow remaining in the ll-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 2 ... ----------------------------------------~~- I I I I I I I I I I I I I I I I I I I 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 ll-foot by 7-foot RCB outlet, the flow divider wall in the RCB, 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 lOO-year floodplain and floodway associated with the proposed improvements. Since the Flood Insurance Study only includes a 100-year analysis for Cal avera Creek, this CLOMR only includes lOO-year analyses. The analyses are described below and electronic files are included on the CD at the back of this report. HEC-l Analysis An updated 100-year hydrologic analysis for the Calavera Creek watershed was performed using HEC-l. The watershed was originally delineated by Rick Engineering Company (under contract with the city of Carlsbad) using the United States Geological Survey's quadrangle maps (see the HEC-l Workmap in Appendix A). Rick performed field investigations to verifY the watershed boundaries. The HEC-l Work Map also includes the Agua Hedionda Creek watershed; however, this CLOMR and the HEC-l analysis is only for the Calavera Creek watershed (Drainage Basins CI-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 this CLOMR. In order to model this CLOMR's improvements, Rick's HEC-l analysis was modified based on the attenuation at Detention Basin BJB, the flow split within the ll-foot by 7-foot RCB, and the 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-l analysis and support material is included in Appendix A. The Detention Basin BJB, park site, 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-l. 3 I I I °1 I I I I I I I I I I I I I I I 1 00-Year Flow Ponded Water Location Rate, cfs Surface Elevation, feetMSL Upstream of Detention Basin BJB 1,501 76.4 Exiting Detention Basin BJB 971 Entering 84" RCP below Split 473 Continuing in 11 'x17' RCB below Split 498 Calavera Creek at Confluence with 909 Agua Hedionda Creek Exiting 84" RCP 497 Low Lying Area at 84" RCP Outlet 35.3 Entering 8'x8' RCB under EI Camino Real 545 . Table 1. lOO-Year HEC-RAS Flow Rates The post-project floodplain within Detention Basin BJB is based on the ponded water surface elevation from the HEC-I 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 ll-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-l 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 Cal avera 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 4 I I I I I I I I I I I I I I I I I I I 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 IOO-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 IOO-year flow rate was obtained from the HEC-I 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 II-foot by 7-foot RCB. A portion of the flow will be directed into the 84-inch RCP and a portion will continue downstream in the II-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 ll-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 5 I I I I I I I I I I I I I I I I I I I detention, a flow split, and cUlverts/pipes. This system will protect the project from flood inundatio1\ 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 lOO-year flows will be contained in culverts and pipes. The required CLOMR forms are included after the figures. 6 -- -- ~ ON THIS PANEL IS LOCATED WITHIN RANGE 4 WEST AND ,TOWNSHIP 12 SOUTH, 0768 I I - ----- ZONE X Calavera Creek-----...: Split Flow ---- l---Calavera Creek '----------_______ -"('-.-...JI 33°09'22" 117°16'52" -- -- APPROXIMATE SCALE IN FEET 500 0 500 E3 E""'3 E3 I NATIONAL FLOOD INSURANCE PROGRAM FLOOD INSURANCE RATE MAP SAN DIEGO COUNTY, CALIFORNIA AND INCORPORATED AREAS (SEE MAP INDEX FOR PANELS NOT PRINTED) NUMBER ~ SUFFIX 060265 0166 060294 0700 01)0297 0'700 MAP NUMBER 06073C0766 F EFFECTIVE DATE: JUNE 19,1997 - -- -- - ---- -- -- ZONE X ZONE X ----- APPROXIMATE SCALE IN FEET 500 0 500 FA E3 f*3 NATIONAL FLOOD INSURANCE PROGRAM FLOOD INSURANCE RATE MAP SAN DIEGO COUNTY, CALIFORNIA AND INCORPORATED AREAS (SEE MAP INDEX FOA PANELS NOT PRINTED) ~PANEl.§!!.!:Ef!l 050285 07ee MAP NUMBER 06073C0768 F EFFECTIVE DATE: JUNE 19, 1997 - ..... -----------------------------------~~~~------- I I I I I I I I I I I I I I I I I I I ... ~:l:~~:./;.,>.: ~~£~~ Figure 4.
