Dear Mike:
O
J
W
Paragon Point PUD is proposing to build 28 foot wide public
D
streets on a "hammer head" cul-de-sac in Phase 2 within the
development. According to the Fort Collins Design Criteria
Q
and Standards for Streets, this street width will require a
Z
a
variance by the City of Fort Collins.
r
mThe
reasons for requesting/granting this variance are listed
M
below:
- The streets proposed to be 28 feet wide will have less
than 750 ADT on them. This cul-de-sac has a maximum
dwelling unit count of 20 D.U.Is. This area would
generate 200 daily vehicle trips at the point where it
intersects with Southridge Greens Boulevard. This volume
is far below the threshold level in the "Fort Collins
Standards." There is not likely to be any external
traffic passing through this cul-de-sac. Therefore, the
aforementioned traffic volumes will be a worst case
level.
- The street that is proposed to be 28 feet is a cul-de-
sac.
- The cul-de-sac does not access an arterial street.
CD
- This is primarily a large lot development. The density
is considered to be medium (2.1 to 6.0 dwelling units per
w
acre). Based upon criteria in "Recommended Guidelines
_
for Subdivision- Streets, A Recommended Practice,"_
w
Institute of Transportation Engineers, 1984, the pavement
ui
J
width should be 28-34 feet. The proposed 28 feet meets
this recommended practice.
•
- Typical developments with large lot sizes provide more
v
o
than four off-street parking spaces per dwelling unit.
a
A comparable development is the First Filing of Clarendon
J
W
s
Hills. Based upon observation at various times on a
o
a
number of days, the average number of vehicles parked on
a
Hinsdale Drive in Clarendon Hills was 3 in a length of
•
-a
1300 feet. This observation was conducted where there
•
were dwelling units on both sides of the street. The
3
LL
number of parked, on -street vehicles would enable
w
"
a
Hinsdale Drive to have been a 28 foot wide street with
no traffic or parking problems.
F-
Q
I recommend that this cul-de-sac street in Phase 2 street in
Paragon Point PUD be 28 feet wide (curb to curb). I would
further recommend that parking be allowed on both sides of the
streets, if at least four off—street parking spaces are
provided per dwelling unit.
If you have any questions or desire additional information,
do not hesitate to call me.
Sincerely,
Matthew-J. Delich, P.E.
