AGENDA REPORT MOORPAR �� OF MOORPARK, CALIFORNUI C = TY OF City Council Meeting of %�?.� —,,i99—Z TO: The Honorable City Council ACTION: FROM: Kenneth C. Gilbert, Director of Public5l Dirk Lovett, Assistant City Engineer BY;. DATE: June 20, 1997 (CC Meeting: 7-2-97) SUBJECT: Consider Approval of Conceptual Design for Casey Road EXECUTIVE SUMMARY This requests approval of a conceptual design for Casey Road street improvements proposed to be constructed in conjunction with the construction of an Elementary School on the old High School site. DISCUSSION A. Request The City is in receipt of a conceptual design for Casey Road improvements to be constructed by the Moorpark Unified School District. A typical cross-section for those proposed improvements is attached as Exhibit 1. B. Recommended Concept The recommended street cross-section for Casey Road west of Walnut Canyon Road is identified as County Plate B-5A modified to increase the curb -to -curb and right-of-way dimension from 401 and 53' to 48' and 611, respectively. This recommended design is consistent with cross-section attached as Exhibit 1. C. Design Comments 1. Known Factors: The above street design standard, as applied to the constraints posed at this location, provides for the following: a) a curb -to -curb street width of 48 feet; b) a street right-of-way width of 61 feet; c) one 12' wide travel lane in each direction; d) one 12' wide combined parking / Bike Lane in each direction; e) a 6 21 area between the curb and the right-of-way line (both sides of the street) to accommodate sidewalks and retaining walls; Casey Casey Road Improvements July 2, 1997 Page 2 f) this design leaves the intersection with Walnut Canyon Road at it present location (It does not provide for alignment with Wicks Road); g) final street improvements at the intersection of Casey Road and Walnut Canyon Road can be designed to function properly within the existing and proposed right-of-way. 2. Unknown Factors: The above street design standard does not address or include the following: a) no dedicated left turn lanes are provided at the entrance(s) to the school; b) no left turn lane for the east -to -north turning movement at the intersection of Casey Road and Walnut Canyon Road; [Note: A left turn lane could be provided, if necessary, if parking was prohibited within that portion of the street where the turning lane and required transitions would be located. The striping design could be: 6' - 121 - 12' - 12' - 61] c) no landscaped parkway within the street right-of-way; d) the location of any required public service easements [normally five feet (51) wide] are not shown [it is not known if such easements can be accommodated outside of the street right-of-way given the close proximity of certain structures]; and, e) no consideration was given to constraints posed by existing topography, vertical alignment, height of required retaining walls, construction of transition between proposed street improvements and existing driveways, etc. D. Partial Implementation It is the understanding of staff that it is the intent of the Moorpark Unified School District (MUSD) to proceed with partial implementation of this conceptual plan. That is, it their intent to convey certain street right-of-way to the City and to proceed with the construction of street improvements to the south side of the street only, at and east of the existing gymnasium. This proposed partial implementation of the conceptual plan yields certain additional problems, briefly described as follows: 1. Vertical Road Alignment Fixed: The construction of a portion of the "ultimate" improvements at this time "fixes" the ultimate vertical alignment of the roadway. It is the understanding of staff that there has been no attempt to determine if the vertical alignment of the curbs and street widening to be constructed by MUSD will be compatible with the design for the ultimate street improvements to extend to the west. If the vertical alignment of these future improvements must change, it will be necessary to reconstruct the street improvements to be constructed by MUSD. That future possible reconstruction could require additional retaining walls to accommodate the vertical changes. casey QUI 0 7S Casey Road Improvements July 2, 1997 Page 3 2. Interim Street Width: The above described conceptual plan allows for parking and Bike Lanes on both sides of the street. However, when the proposed limited south side improvements are constructed by MUSD, it is anticipated that the street will not be wide enough to accommodate any on -street parking or Bike Lanes. It appears that the benefits of the subject conceptual design will not be realized with these interim improvements, but will only be attained after the complete conceptual design is constructed. E. Future Traffic Needs This conceptual design ... 1. exceeds the current requirements of the Circulation Element of the Moorpark General Plan [Local Collector: R-O-W of 50' to 7011, with minimum curb -to -curb width of 401]; 2. accommodates the traffic generated by the existing and proposed land uses being contemplated by the Moorpark Unified School District; 3. accommodates [at LOS A] the projected traffic needs of Specific Plan No. 1. [ Note: Specific Plan No. 1 also requires the installation of a traffic signal at the intersection of Casey Road and Walnut Canyon Road. The completion date for this improvement (first occupancy, build -out, etc.) has not yet been determined.] 4. may not fully accommodate the traffic needs of Specific Plan No. 2 or other areas which may be served by this roadway; 5. may not accommodate the future traffic needs of local and regional traffic which may use this route when and if Casey Road is ever extend through to Gabbert Road; and, 6. places the south curb of Casey Road at its ultimate location. [Note: Existing structures on the south side of the street do not allow future widening to the south. Any future street widening beyond that contemplated by this concept will have to come from the north side of the street. It appears that such additional street widening may require the removal/relocation of existing residential structures on the north side of the street.] RECOMMENDATIONS Staff recommends that the City Council approve the proposed street design for Casey Road street improvements to serve the School property, as set forth in this report.

Four -I anc Arterial - A four -lane roadway with a typical right- uf-wry width of 80-100 feet and a curb to curb pavement width of 60 60 feet, and which may have controlled access and restricted parking. Iturl Collector - A two- to four -lane roadway with a typical right-of-way of 70-90 feet and a curb to curb pavement width of 54-64 feet. An upgrade from two to four Lana is to be determined as development occurs in rural areas within the city sphere. 1 ocal Collector - A two-lane roadway with a typical right-of-way width of 50-70 feet and a curb to curb pavement width of 36-54 feet. Industrial areas would require the wider dimension to allow for a center turn lane and to provide more space for truck maneuvering. In hillside areas, the minimum dimension may be allowed, but graded shoulders are required and on -street parking is prohibited in order to provide extra safety. 10' B. 12'12' 12' 12' 12' 80' — 100' R ON 10' 8' 12' 12' 12' 12' 70' — 90' R O.W 10' B. 12' 12' 8' 10' 50' — 70' R.O.W.
