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;

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.

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.

Six -lane Arterial - A six -lane roadway with no on -street
parking, a typical right-of-way width of 110-120 feet and curb
to curb pavement width of 90-104 feet, and which may have
euntrullcd access.
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.
