RE: CALDERA CANYON — STAFF REPORT COMMENTS
In response to several items contained in the Staff Report please see comments below.
1. Extension of shared driveway Lot 8, Block 2:
a. The shared driveway has a pavement length of 150 -feet. The remaining area of the
common lot is dedicated to a storm water facility. Driveways for Lots 7 and 11, Block
2, can begin at the end of the pavement and sweep inward to the concrete garage apron.
b. There are only two options: 1. an additional residential lot with a hammerhead turn-
around for the Fire Department as shown here, or 2. an internal access to the existing
residence.

c. With the need for a hammerhead at the end of the shared driveway (longer than 150 -
feet) there is only room for one additional lot.

d. With the need for a hammerhead at the end of the shared driveway (longer than 150 -
feet) there is only room for one additional lot.
e. With the internal driveway for the existing home, there will not be enough space for an
additional lot. The driveway would have to intrude into almost the entire width of the
20 -foot landscape buffer to provide marginal turning radius for access to the residential
garage.
2. Waiver to keep existing driveway access:
a. Granting a waiver to keep existing driveway access has no impact on the trip counts on
Leigh Field as these trips are already accounted for in traffic counts. Leigh Field feeds
a very stable and essentially fully developed area with the exception of the current site
and the parcel to the east. The parcel to the north as multiple options for access via
Green Haven Street as well as the stub street being proposed with the site and the stub
street already provided for with Quinzer Commons No 10.

3. Stub Street to East:
a. The subject site and the parcel to the east are both overlaid with a N.C. (Neighborhood
Commercial) designation. Cross connectivity between an exclusively residential
subdivision and a mixed use parcel including commercial would compromise the
residential character of the proposed subdivision.
b. There is no location for a stub street that would not run into an existing structure: 61 -
feet to the northern barn; 118 -feet to the residence; and 116 -feet to the southern barn.
c. The frontage for the parcel to the east along Leigh Field is approximately 492 -feet, and
with the ability to align with access points on the south side of Leigh Field, this parcel
can meet ACHD policy for offset on a residential collector from an arterial roadway.
4. Densit :
a. The proposed subdivision density is at the lower margin of preferred density for a
mixed use area. An additional stub street to the east would further reduce density by
one to two lots.
5. Landscape Buffer:
a. Currently there is a dense row of arborvitae along the Leigh Field frontage. Adding 4
additional trees would require removal of healthy and mature vegetation.
b. An option may be to replace arborvitae with trees as these bushes reach the end of their
life cycle in the future.
