BACKGROUND: On August 5, 1991 the Traffic Safety Commission discussed the request for signalization of the Rancho Santa Fe Road/Questhaven Road intersection. For that meeting, the Traffic Safety Coordinating Committee (TSCC) recommendation to the Commission was to continue this item six months due to the many outstanding issues regarding Rancho Santa Fe Road. These issues included: • design of the Rancho Santa Fe Road (RSF) realignment • EIR preparation for the Rancho Santa Fe Road realignment • environmental concerns • endangered species • grade separation of the future RSF /Questhaven intersection • annexation of land in this vicinity by the City of San Marcos • adjacent proposed development approvals in San Marcos • funding of the realigned Rancho Santa Fe Road • timing of when the new RSF would be constructed • funding source for the signal at the existing RSF /Questhaven Road intersection The Traffic Safety Commission concurred with the TSCC recommendation and by a 5-0 vote, recommended that this matter be continued for six months when an update of information on the issues would be available. Staff was asked to report the status of outstanding issues at the continued meeting. Design plans for the RSF realignment are currently being prepared. It is anticipated that ultimate funding of the construction costs will be by an assessment district. TRAFFIC SAFE1Y COMMISSION Staff Report COMMISSION MEETING OF: February 3, 1992 (Continued) ITEM NO. 6A A significant issue regarding the RSF alignment is the potential listing of the California gnatcatcher as an endangered species. The City of Carlsbad is continuing to work with the wildlife resource agencies to develop a Habitat Management Plan to offset the impacts from road construction and mass grading. The final environmental impact report for the proposed Rancho Santa Fe Road realignment and mass grading is tentatively scheduled for City Council action on March 24, 1992. At that meeting the City Council will review alternatives for the project that include: • realign Rancho Santa Fe Road and defer proposed mass grading; • realign Rancho Santa Fe Road with mass grading of developable land consistent with the General Plan; • road widening in the existing alignment and defer proposed mass grading; • road widening in the existing alignment with mass grading of developable land consistent with the General Plan; • road widening in the existing alignment with mass grading for proposed development; • no project. Section 2 (Executive Summary) and Section 3 (Project Description) from the final EIR is attached for information purposes for the Traffic Safety Commission. The City of Carlsbad Engineering Department has requested, in writing, that the City of San Marcos participate in the costs for design, construction and operation and maintenance of the request traffic signal. This request is being reviewed by City of San Marcos City officials with a decision tentatively expected by mid-February. Depending upon their response, the issue would be scheduled for consideration by the City of San Marcos Traffic Safety Commission at one of their future meetings. However, the existing intersection of Rancho Santa Fe Road/Questhaven Road is Number 3 on the Traffic Signal Priority List for San Marcos. DATA:. Rancho Santa Fe Road is classified on the City of Carlsbad circulation element as a prime arterial and serves as the primary north-south route between Interstate Highways 5 and 15. Questhaven Road is classified on the. City of San Marcos circulation element as a secondary arterial. Questhaven Road serves a small community known as Elfin Forest and is also the primary access to the County TRAFFIC SAFE1Y COMMISSION Staff Report COMMISSION MEETING OF: February 3, 1992 (Continued) ITEM NO. 6A landfill. This roadway has been the focus of development and realignment proposals for both San Marcos and Carlsbad. The City of Carlsbad Local Facilities Management Plan Numbers 11 and 12 have identified the need and funding source for improving this stretch of roadway. In 1990 the City of Carlsbad approved a realignment of Rancho Santa Fe Road including the Questhaven Road intersection. Although designated as a prime arterial, Rancho Santa Fe Road is currently constructed as a rural, two lane roadway with spot widening at the Melrose Drive, La Costa Meadows Drive and Questhaven Road intersections. Lane geometrics · at the Questhaven Road intersection are shown on Exhibit lA, attached. The City of Carlsbad has previously approved Rancho Santa Fe Road as a truck route in both directions north of Questhaven Road. However, the City has restricted the direction of truck traffic to northbound only from Olivenhain Road to Questhaven Road when using Rancho Santa Fe Road. Existing 24-hour traffic volumes from a recent traffic count on Rancho Santa Fe Road and Questhaven Road are provided in Table 1. TABLE 1 -INTERSECTION APPROACH TRAFFIC VOLUMES STREET DIRECTION CURRENT ADT June 18-19, 1991 January 8-9, 1992 Rancho Santa Fe Rd NB 9,845 10,163 Rancho Santa Fe Rd SB 10,687 10,605 Questhaven Rd WB 2,445 1,854 Land adjacent to the subject intersection is undeveloped. One of the parcels is in process for discretionary approvals in San Marcos and is known as University Commons. The final EIR for University Commons has identified improvement, realignment and signalization issues for the Rancho Santa Fe Road/Questhaven Road intersection and was certified recently by San Marcos City Council. Existing geometrics and pavement markings at Rancho Santa Fe Road and Questhaven Road are shown on Exhibit 1. The roadway is considered rural with widening and realignment planned in the near future. The intersection has been identified as qualifying for a future traffic signal (No. 2 on the City of Carlsbad 1992 Traffic Signal Qualification List), however, funding has not been allocated at this time. TRAFFIC SAFE1Y COMMISSION Staff Report COMMISSION MEETING OF: February 3, 1992 (Continued) ITEM NO. 6A Two speed surveys were conducted on Rancho Santa Fe Road on July 23, 1991. Results of the surveys are indicated in Table 2. Table 2 -Speed Surveys on Rancho Santa Fe Road Location At La Costa Meadows Dr. At Questhaven Road Critical Speed Pace Speed % in Pace 50 39 to 49 73 52 44 to 54 76 Although a significant number of vehicles use the intersection, more than 90% of the vehicles entering the intersection are on Rancho Santa Fe Road. Fortunately, the collision rate is low. Channelization at this intersection has been designed and implemented to reduce conflicts and facilitate the movement of traffic. As stated previously this location has been rated No. 2 on the City of Carlsbad 1992 Traffic Signal Qualification List. Specific funding for the proposed traffic signal has not been identified. However, the City of San Marcos has been requested to participate in funding the traffic signal via an inter-agency cooperative agreement. RECOMMENDATION: The Traffic Safety Coordinating Committee recommends that a traffic signal be installed at the intersection of Rancho Santa Fe Road and Questhaven Road. NECESSARY CI1Y COUNCIL ACTION: A resolution by City Council will be required to initiate design and construction of the traffic signal at the existing intersection. The funding for this signal will be determined by staff prior to presenting to City Council for action. RECEI.,,ED MAY 2·9 1991 CITY OF CARLSBAD ENGINEERING DEPARTMENT Mr. Bob Johnson -Traffic Safety Ci ty of Car lsbad 1200 Carlsbad Village Drive Carlsbad, CA 9 2008 Dear Mr. Johns on, Ma y 26, 1991 Engineer We hav e been traveling Rancho Santa Fe Road and Questhaven Road for eleven years . It is now e x tremely dangerous and impossible to fee l safe while u tilizing this intersection. For the following reasons, please install a signal or stop signs as soon as possible. 1. The traffic count warrants a signal. 2. The traffic often exceeds 55 M.P.H .. 3. The heavy truck traffic blocks views both to the north and south. 4. Driver behavior cannot be predicted due to confusion over the short stretch of unusual FAST /SLOW and SLOW /FAS T lanes (the southbound left lane on Rancho Santa Fe Road is t he slow lane for autos turning onto the road, and the r ight lane is for traffic which is already traveling at h igh speed) . 5. Dr ivers are passing within the intersection by utilizing the merge lane. 6. I t i s very difficult to estimate the speed of northbound t raffic approaching the intersection because most cars are accelerating while coming down the hill. 7. Nume rous trucks have overturned due to excess speed, the te rrain, and perhaps confusion at this intersection. 8. Sout hbound traffic on Rancho Santa Fe Road is now beginning to back up to the Melrose intersection due to the large number of trucks turning left onto Questhaven Roa d but must wait for right-of-way. 1 9. Rec ently, I have been frightened, frustrated and end angered when turning south behind the Coast Waste Ma n agement Trucks. Many times, the trucks immediatel y went to the right "FAST" lane. This creates a real dangerous situation. I am correctly utilizing the Slow left lane, so we both block the fast traffic in the right lane . If this is difficult to understand, try driving i t~ I am writing t his with a positive attitude, hoping that stop signs and warning l ights will be installed immediately as an interim solution unt il developers' funds will finance signal lights. This i ntersection is chaotic! Please help us to avoid further accidents. Sincerely, Linda Ankrom 2 >-<[ :3 w w Cl:'.'. l.__,.__ l0 I ......... VICINITY ( POINSETTIA LN. ALICANTE RD.

The project proposes relocation of existing Rancho Santa Fe Road easterly to the "Canyon alignment," replacing the bridge over San Marcos Creek, and expansion of the road into a six-lane prime arterial between La Costa Avenue and Melrose Drive as called for in the Circulation Element of the General Plan. Mass grading to provide for future development is to occur on both sides of the roadway. A General Plan Amendment of the Land Use Element will be a future action and is not a part of this project. PROJECT LOCATION The 768-acre project site is located in the eastern portion of the City of Carlsbad, along both sides of the existing Rancho Santa Fe Road between La Costa Ave nue and Melrose Drive. Land surrounding the project site includes residential subdivisions to the south and west, San Marcos Creek to the west and north, the City of San Marcos to the north and east, and County lands to the east. Cities affected by circulation improvement of the realigned roadway include Encinitas to the south, Oceanside and Vista to the northwest, San Marcos to the north, and Carlsbad. Interstate 5 lies approximately 3.5 miles west of the project site. ENVIRONMENTAL IMPACTS The City Planning Department prepared an Initial Study for the proposed project and determined the need for an EIR. Environmental issues identified by the City fo r assessment in this EIR consist of: 0 Earth 0 Air Quality 0 Water Resources 0 Biological Resources 0 Noise 0 Light and Glare 0 Land Use 0 Traffic/Circulation 0 Public Services 0 Utilities 2-1 o Landform Alteration/Visual Quality o Cultural/Historic Resources SIGNIFICANT UNMITIGATED IMPACTS, OVERRIDING CONSIDERATIONS, AND ENVIRONMENTALLY SUPERIOR ALTERNATIVES Based on these data and conclusions in this EIR, the City finds that the project will result in significant impacts to air quality and biological resources (Diegan coastal sage scrub habitat and the California gnatcatcher) which cannot be fully mitigated. Impacts to Diegan coastal sage scrub habitat and the California gnatcatcher will be mitigated to a level of less than significant with the approval of a Habitat Conservation Plan and/ or an agreement to prepare such a plan. Implementation of the mitigation measures outlined in this document can reduce all other impacts to less than significant levels. Table 2-1 summarizes the findings of the analysis. A number of constraints to the project, such as steep slopes and sensitive biological and archaeological resources, pose obstacles to project implementation. Project constraints are shown in Figure 2-1. The Road Widening in the Existing Alignment and Defer Proposed Mass Grading Alternative and the Realign Rancho Santa Fe Road and Defer Proposed Mass Grading Alternative are environmentally superior to the proposed project. Implementation of the proposed project will require issuance of a Statement of Overriding Considerations by the City. SPECIAL AREAS OF CONCERN IDENTIFIED IN THE FOLLOWING DOCUMENT The following items are just some areas of special concern associated with the project: o Placement of the roadway relative to existing homes in the La Costa Vale subdivision, and the potential noise impacts to residents from construction of a prime arterial along the existing alignment. o Destruction of 217 acres of coastal sage scrub habitat and the resultant loss of 14 pairs of California gnatcatchers while state and federal resource management agencies are considering placement of the species on the endangered species list. o Mass grading without development proposals. 0 Grading in areas currently designated as Open Space. 2-2 ISSUES TO BE RESOLVED The fo llowing issues are to be resolved as part of the project at a later date following environmental review: 0 0 0 0 0 0 Sec Section 9.0 O Response 2F Formulation of the project financing mechanism for roadway construction.

The City has determined that a roadway realignment is necessary to accommodate construction of Rancho Santa Fe Road as a six-lane prime arterial. Rancho Santa Fe Road is presently designated in the Circulation Element of the Carlsbad General Plan as a six-lane prime arterial, but the portion of the road between Questhaven and Melrose may ultimately be constructed to eight lanes to support the additional traffic volume generated by newly planned development in the southerly portion of the City of San Marcos. Realignment of the roadway will be from its present alignment to the "Canyon Alignment", which moves the portion of the road between Melrose Avenue and La Costa Avenue approximately one-quarter mile east of its present location (C- 2). The Carlsbad City Council voted in 1987 to place Rancho Santa Fe Road in the proposed alignment. The City is therefore proposing this alignment for the project. The City has determined that this alignment is consistent with the roadway location shown in Figure 3-1, the General Plan Circulation Element Map. In conjunction with road construction and to prepare for subsequent development of surrounding land according to the General Plan, there are properties adjacent to the new roadway realignment and improvements that are proposed by Fieldstone/La Costa Associates to be mass graded. Funding fo r the project will be acquired by formation of the Rancho Santa Fe Road Assessment District, which is proposed as the 2,210 acre area considered to directly benefit from roadway improvements (shown in Figure 3-3). The actual Assessment District boundary and acreage may be adjusted when the District is formed. The project will be financed through the issuance of bonds in accordance with the Improvement Bond Act of 1915 or some other public financing mechanism. Property owners within the Assessment District will be assessed funds which will be used to pay the principal and interest of the bonds. Mass grading of 348 acres of land surrounding the roadway is required to ensure development within the Assessment District prior to roadway financing. Although the project area encompasses the entire Assessment District, analysis in this Environmental Impact Report (EIR) will be limited to the area affected by changes to the physical environment associated with roadway realignment, improvement and mass grading ( approximately 448 acres). This action will also necessitate a future redistribution of surrounding General Plan land uses requiring a subsequent amendment to the Land Use Element of the General Plan and the Master Plan for the La Costa southeast area. 3-1 BUENA VISTA LAGOON AGUA HEOIONOA LAGOON PACIFIC OCEAN ~ Railroad -Freeway -Prime Arterial -Major Arterial Secondary Arterial Collector Street ~ North Rancho Santa Fe Road EIR 3-2 CARLSBAD CITY LIMITS I I I I -fl.._..J SOURCE: City of Carlsbad General Plan Figure 3-1 Circulation Plan WAACOS Ji }i -f As a direct result of the roadway realignment, land uses designated in the Land Use Element of the General Plan and the La Costa Master Plan which lie adjacent to the new road reaiignment will have to be redistributed, requiring a General Plan Amendment and Master Plan Amendment. The General Plan Amendment will result in changes to acreages of residential land, open space, office and commercial acreages. However, no net change in the number of residential dwelling units will occur. Although the General Plan Amendment and Master Pl an Amendment are not being considered at this time, potential environmental effects of the amendments are addressed in this EIR as the project proposes a land use distribution which would be that of the amended plans. The Regional wcation Carlsbad is located on the coast, approximately 30 miles northwest of downtown San Diego, as shown in Figure 3-2. The City encompasses a 40 square mile area immediately north of the City of Encinitas, south of the City of Oceanside, and extends inland from the Pacific Ocean to the foothills of the Peninsular Range Mountains to the east. The wcal Vicinity The project location, shown in Figure 3-3, -consists of undeveloped land along both sides of Rancho Santa Fe Road. Boundaries coincide with those of the proposed Rancho Santa Fe Road Assessment District, and are delineated by Carlsbad city limits to the east and south, El Camino Real to the far west, undeveloped areas south of Levante Street to the southwest, the existing Rancho Santa Fe Road to the west, and the street system of Corintia Street, Xana Way, Alga Road and El Fuerte Street to the north and west. The most northerly and easterly boundaries lie adjacent to the City of San Marcos. Zone 11 of the Local Facilities Management Plan (City of Carlsbad) also lies within these boundaries. Rancho Santa Fe Road extends through the eastern portion of La Costa, which lies within the southeast quadrant of Carlsbad. The road is a primarily north- south road link in the circulation systems of the Cities of Carlsbad, San Marcos and Encinitas. The project covers the 2,210 acre Assessment District area, which includes two miles of the Rancho Santa Fe road right-of-way (31 acres) and approximately 768 acres of land comprising the project area. Approximately 21 acres of the Stanley Mahr and Denk Reservoirs located within project area boundaries are not part of the project. The topography of the project area is hilly, containing a series of drainages and ridges. The ridgeline in the northernmost portion of the area reaches over 990 feet in elevation, then quickly drops to the south along a 24 percent slope to the head of an intermittent drainage course (C-3). The slopes elsewhere in the project area are not as severe. Vegetative cover types include coastal sage scrub, chaparral, grassland, oak woodland, riparian woodland, elderberry woodland, and 3-3 ... ,...____ l a.Biverside c.2,u_nt~y ___ _ Oceanside (78) Carlsbad Encinitas 0 5 10 ~ North scale in miles San Diego County ~ () ~ ~ San o Marcos o • ' _ _.,.r--,:(78) Project Location • Poway 3-4 Figure 3-2 The Regional Location \ Rancho Santa Fe Road Assessment District Boundary , I ✓-I ,_,,-I ~ _,,.,,-I • @',, (r ; L.---- il~~;,~:tF 1~----...- ~8 1' North 0 250 scale in feet Rancho Santa Fe Road EIR Project Boundary ~ 3-5 8 SOURCE: City of Carlsbad Figure 3-3 The Project Location A eucalyptus. Land uses surrounding the project site include residential and vacant land to the north, west; and south, and open space to the east. PROJECT OBJECTIVES The City of Carlsbad is proposing to construct Rancho Santa Fe Road as a six- lane prime arterial, requiring realignment of the roadway and subsequent General Plan Amendment to redistribute the General Plan land use designations for the area surrounding Rancho Santa Fe Road. Newly planned development in the south portion of the City of San Marcos may cause the need for the ultimate construction of eight lanes between Questhaven Road and Melrose Avenue. While the proposed project will include evaluation of impacts for the ultimate eight-lane facility, grading and improvements for only six lanes is proposed under Sec Section 9.o the Assessment District. Mass grading and subsequent development of land Response 5N surrounding the road will generate funds required for road improvement and are also objectives of the project. Widening of the existing roadway will provide the prime arterial shown in the Circulation Element of Carlsbad's General Plan. Community benefits from this project will include reduced congestion, improved traffic flow and increased safety for travelers on the roadway. Additionally, this road realignment will provide a vital link in the region's roadway network. PROJECT CHARACTERISTICS The proposed realignment project will be accomplished in three phases: Phase I is to include mass grading of land owned by Fieldstone /La Costa Associates and M.AG. Properties surrounding the existing Rancho Santa Fe Road, including a possible school site and establishment of the subgrade for the future alignment of Rancho Santa Fe Road as shown in Figure 3-4. Grading will be staged to preserve existing utilities at their present locations until relocation of the roadway in Phase II is completed. Although rough grading west of the existing Rancho Santa Fe Road will be initiated in Phase I, completion of the mass grading in this area will take place as part of Phase III. Phase II will include the relocation of the existing facilities (roadway lighting, drainage, signage) to the completed new alignment between La Costa Avenue and a temporary detour south of Questhaven Road as shown in Figure 3-5. Construction of improvements for the new Rancho Santa Fe Road location will be accomplished during this phase. The existing Rancho Santa Fe Road will . remain in place and open to traffic during Phase II along the frontage of the La Costa Vale subdivision (CT 76-3, Map No. 8583 and CT-72-20, Unit 3, Map No. 7950), and potentially from Cadencia Street southerly to the boundary of the Fieldstone and M.AG. properties where it will be realigned to connect with the proposed Rancho Santa Fe Road realignment. The realigned Rancho Santa Fe Road between La Costa Avenue and the temporary detour will be opened at the completion of Phase II. 3-6 a Pro1ect B.>\rda,y EJ Assessment OiHict Bound--, E3 Fuve Ao.dWay E3 Existing Roaoway -Construction Area (Generalized) a 1400 'r North scale in feet Rancho Santa Fe Road EIR Melrose ~•~ \~I 1 Corlnlle Stre~ .... :: : :: : :: :: :::: ::: ................ . . . . .. \ \ ,,,-::::::=== Ei:isllng La Coste Meadows Drive E1isting Ouellhavan Road Future Ouasthavan Road ••,:•,,:,,:•••:• ,,;,ft; • Reurvolr I I SOURCE: Project Design Consultants Figure 3-4 Phase I of the Proposed Project 3-7 a Pro1ect 8,)'6'da,y EJ Asaesamem Oiark:t Bounc:la,y B Fuue Roaoway a EaislinQ RoaOw1y ConstructJon Area (Generalized) a 1400 ~ North scale in feet Rancho Santa Fe Road EIR Molron Dro~ \~I 1 Corlntla Str•1""~ j) // I \ \ -:;::=:== E1i,tlng La Costa Meadows Orl't'e E1.lsting Ouestflaven Road Future Ouestt,1ven Road Temporary Detour SOURCE: Project Design Consultants Figure 3-5 Phase II of the Proposed Project 3-8 A Phase ID consists of two components as shown in Figure 3-6: A) completion of Rancho Santa Fe Road, and B) the grading construction program. In Phase IIlA, the surface of the existing Rancho Santa Fe Road (west of the new alignment) between the northerly boundary of the La Costa Vale subdivision and the temporary detour will be graded along with completion of the mass grading of the areas west and east of the proposed Rancho Santa Fe Road realignment. This will occur after traffic is rerouted onto the new alignment of Rancho Santa Fe Road constructed in Phase II. A segment of the existing Rancho Santa Fe Road will be preserved to provide a possible connection between Rancho Santa Fe Road and the existing La Costa Vale subdivision. Phase IIIB will include construction of the northern section of Rancho Santa Fe Road, between the temporary detour and Melrose Avenue (including the San Marcos Creek bridge, and extension of Questhaven Road to the new alignment of Rancho Santa Fe Road). Grading of the project area will be accomplished by cut and fill activity on approximately 448 acres. The grading associated with the road realignment and interim grading of the areas east and west of the new road alignment within the Fieldstone ownership will consist of movement of 3.4 million cubic yards of earth cut, including grading for the road only through the M.AG. ownership. Grading within the M.AG. Properties will be approximately 797,000 cubic yards of cut for a total of 4.2 million cubic yards. Figure 3-7 shows the approximate area of disturbance that will be involved in the roadway construction and realignment, which includes the grading program and locations of new intersections. This area includes the right-of-way for the new roadway, rights-of-way for the extension of existing roadways to connect with Rancho Santa Fe Road in its new location, and grading that will be required to create the roadbeds and to rough grade pads for future development. Intersections that will be affected by the project include, from north to south, Rancho Santa Fe Road and Melrose Drive from the north (intersecting in the alignment as reflected on the Tentative Map and public improvement plan for the Meadowlands project, CT 85-19), La Costa Meadows Drive to the east, existing Questhaven Road to the east (proposed to be extended to meet Rancho Santa Fe Road), the existing intersection of Cadencia Street and the existing Rancho Santa Fe Road to the west, a future Melrose Avenue to the southeast (which is not considered a part of this project), and La Costa Avenue as an east to west cross-street. Two alternative configurations for the Rancho Santa Fe Road/Melrose Drive intersection include Rancho Santa Fe Road forming a 'T' into Melrose Drive and Melrose Drive forming a 'T' into Rancho Santa Fe Road. Land use redistribution within the project area will result in no net change in the number of residential units currently allowed. However, as shown in Table 3-1 the acreages of several land uses designations will change as a result of subsequent General Plan Amendment. A substantial decrease in acreage of land designated as low density residential will result, accompanied by an increase 3-9 a Project 8.;,Wlda,y EJ An eument Dls.-.Ct 801610.-y B Fuue AoeOW■y B ExlatinQ Roadway mmTITITIITJ Construction Area ~ (Gene r a Ii z e d) 0 1400 ~ North scale in feet Rancho Santa Fe Road EIR ,...-::;:::=== Existing L■ Costa Meadows Drive Existing Oue11haven Road Future Oueathawen Road ····· .. ·::::::::::::;:::::::::::: :-:•:•:-·,•.•:-:.;.:-:-:,·, .•.••••····•·••••· ==-=··-·=·=·=·=·=·=··········· .·.··· ...

Grading not required for roadway relocation will be funded by the abutting private land owners. In order fo r the project to be completed, the City of Carlsbad must complete a series of discretionary actions which include: 1. Certification of the final Rancho Santa Fe Road Realignment and Mass Grading EIR; 2. A subsequent General Plan Amendment, La Costa Master Plan Amendment and Local Facilities Management Plan Amendment associated with redistribution of planned land uses; 3. Approval of the proposed Rancho Santa Fe Road Assessment District or some other funding mechanism; 3-12 4. Approval of a grading plan for the roadway and redistribution of the associated planned land µses; 5. Issuance of engineering, grading, and Hillside Development permits for the construction of Rancho Santa Fe Road and grading for land proposed to be developed. Other permits which will be required include a Section 404 Permit related to the crossing of San Marcos Creek from the U.S. Army Corps of Engineers (USACE), and a Section 1601 Streambed Alteration Permit from the California Department of Fish and Game (CDFG). This project will require subsequent amendments to the Land Use Element of the City of Carlsbad General Plan. In addition, the Master Plan for La Costa and the Local Facilities Management Plan for Zone 11 will subsequently be amended as a separate project, potentially necessitating further environmental review at a later date. These actions are not part of the initial action to be taken by the City and are not a part of this project, these are subsequent actions to occur at a later date. The creation of new roadways for Questhaven Road and the southern extension of Melrose Avenue will be accomplished separately from this project, also requiring separate environmental review. Vacation of existing Rancho Santa Fe Road roadway segments will be a part of Rancho Santa Fe Road construction. Figure 3-8 shows roadway vacation that will occur with Rancho Santa Fe Road construction. Rancho Santa Fe Road serves traffic traveling to and from the Cities of San Marcos, Vista, and Encinitas as well as Carlsbad. Design and installation of roadway improvements will require coordination with officials of all affected Cities. • Alternatives to the proposed project include: o realign Rancho Santa Fe Road and defer proposed mass grading; o realign Rancho Santa Fe Road with mass grading of developable land consistent with the General Plan; o road widening in the existing alignment and defer proposed mass grading; o road widening in the existing alignment with mass grading of developable land consistent with the General Plan; 0 road widening in the existing alignment with mass grading for proposed development; o no project. 3-13 PORTION OF TO BE VACATED 0 1 400 1' North scale in feet Rancho Santa Fe Road EIR PROJECT BOUNDARY PROPOSED lrRANCHO SANTA FE ROAD ; ' I .
