Dear Mike:
(File: 9309LT01)
Stone Ridge Village is proposing to build 28 foot wide public
streets on a number of cul-de-sac streets in the development.
These cul-de-sacs are named Jadestone Court, Jewelstone Court,
and Rosestone Court. According to the Fort Collins Design
Criteria and Standards for Streets, this street width will
require a variance by the City of Fort Collins.
The reasons for requesting/granting this variance are listed
below:
- The streets proposed to be 28 feet wide will have less
than 750 ADT on them. These cul-de-sacs would generate
the following daily traffic: Jadestone Court (8 d.u.) -
80 ADT; Jewelstone Court (20 d.u.) - 200 ADT; and
Rosestone Court (6 d.u.) - 60 ADT. The respective
generated traffic volumes would be at the point where the
cul-de-sacs intersect with either Greystone Drive or
Fieldstone Drive. These volumes are far below the
threshold level in the "Fort Collins Standards." There
is not likely to be any external traffic passing through
these cul-de-sacs. Therefore, the aforementioned traffic
volumes will be a worst case level for each cul-de-sac.
- The streets that are proposed to be 28 feet are all cul-
de-sacs.
z
- The cul-de-sacs do not access an arterial street.
w - This is primarily a large lot development. The density
Z is considered to be medium (2.1 to 6.0 dwelling units per
CD acre). Based upon criteria in "Recommended Guidelines
W for Subdivision Streets, A Recommended Practice,"
Institute of Transportation Engineers, 1984, the pavement
c� width should be 28-34 feet. The proposed 28 feet meets
• this recommended practice.
o - Typical developments with large lot sizes provide more
than four off-street parking spaces per dwelling unit.
o A comparable development is the First Filing of Clarendon
N Hills. Based upon observation at various times on a
a number of days, the average number of vehicles parked on
°-` Hinsdale Drive in Clarendon Hills was 3 in a length of
• 1300 feet. This observation was conducted where there
were dwelling units on both sides of the street. The
number of parked, on -street vehicles would enable
cc
~ Hinsdale Drive to have been a 28 foot wide street with
no traffic or parking problems.
I recommend that these cul-de-sac streets in Stone Ridge
Village be 28 feet wide (curb to curb). I would further
recommend that parking be
streets, if at least four
provided per dwelling unit.
allowed on both sides of the
off-street parking spaces are
Specific concern was expressed about Jewelstone Court, in the
100+ feet north of Fieldstone Drive. This area has additional
on -street parking available in the "open space" frontage north
of lots 61 and 78, and on Fieldstone Drive south of lots 60
and 79. Fieldstone Drive is a 36 foot wide street. While it
remains unlikely that these areas will be used for parking on
a regular basis, they are available should it be necessary.
If you have any questions or desire additional information,
do not hesitate to call me.
