Box 5367 Economics Landscape Architecture Orange, CA 92613-5367 FAX 7141953-69ag An Employee-Owned Company Mr. David Hauser City of Carlsbad 2075 Las Palmas Drive Carlsbad, CA 92009- 1576 Re: Intersections on El Camino Real Dear David: We are presently coordinating with Fieldstone’s engineer (P.D.C.) for the Arroyo La Costa project, across from the Green Valley - Zone 23 project. The subject of concern is primarily the location and number of left-turn pockets on El Camino Real at the future Calk Barcelona and Levante Streets. The present final engineered drawings show a single southbound left-turn lane from El Camino Real to eastbound Calk Barcelona, and no turn pocket for the northbound traffic. This clearly is in conflict with the Zone 12 Local Facilities Management Plan (LFMP) adopted in 1990, and our tentative map (CT92-08) which was filed in November 1992. The LFMP calls for double left-turn lanes, both northbound and southbound for the ultimate condition at Year 2010. It is my understanding that discussions are in progress with the City to determine whether a single southbound left-turn is sufficient for the traffic volumes being projected. I feel it is necessary to point out that the double northbound left-turns are necessary for the Green Valley traffic volumes. In essence, this requirement dictates the design for the ectire intersection, which would require a 24-foot wide median (4 foot nose plus two 10-foot Icft-turn lanes). Regardless of how many southbound left-turn lanes are determined to be necessary, the appropriate transitions should be accommodated on the Arroyo La Costa plans. The problem of revising the plans is insignificant compared with the costly removal and replacement of curbs, pavement, landscaping, drainage structures, and traffic signal detectors if the present design is implemented. - This conflict has been brought to the attention of City staff as early as May 1993 as part of ow ongoing project meetings, with no definitive resolution of the issue. In reaction, my Client has authorized our firm to take a more active role in coordinating the intersection design, and we have started discussions with Fieldstone, P.D.C., and City staff. It appears that all parties involved are willing to cooperate in resolving the alignments and widths. We are concerned, however, with the possibility that the present design (or some slight modification of it) might be approved without full compliance with the Zone 12 LFMP. It is important to note that we are not asking that special consideration be given for a yet-to-be- approved tentative map, oniy compliance with adopted guidelines for a regional facility. I j. ’ Mr. David Hauser City of Carlsbad September 29, 1993 Page 2 of 2 The compromise solution we are requesting is that the City accept our agreement between the Arroyo La Costa and Green Valley ownerships in lieu of full compliance with the Zone 12 LFMP at this time. The agreement would state that a construction change would be initiated after signature of the Arroyo La Costa plans. The revision would ensure that all infrastructure is compatible with both interim and ultimate traffic considerations. This will enable Fieldstone to move forward with other phases of the plan while the plans are being revised. We have prepared a preliminary plan for review by the ownerships, consultants and City staff. I appreciate the critical timing involved, and I hope a mutually beneficial arrangement can be agreed upon. I am available to answer any questions at your convenience. Sincerely, P&D TECHNOLOGIES W.
