Dear Mike:
Z
gFossil
Ridge PUD is proposing to build 28 foot wide public
O
streets on all cul-de-sacs and for Phase 5 streets within the
•
development. According to the Fort Collins Design Criteria
Z)
and Standards for Streets, this street width will require a
Z
Uj
variance by the City of Fort Collins.
a
Z
The reasons for requesting/granting this variance are listed
r
below:
Z
- The streets proposed to be 28 feet wide will have less
°O
than 750 ADT on them. The cul-de-sac with the highest
dwelling unit count (18 D.U.) is located in Phase 4.
This area would generate 180 daily vehicle trips at the
point where it intersects with Southridge Greens
Boulevard. The access streets in Phase 5 will have a
daily traffic volume of 200-300. Both of these are far
below the threshold level in the ."Fort Collins
Standards." There is not likely to be any external
traffic passing through any of the cul-de-sacs or the
Phase 5 streets. Therefore, the aforementioned traffic
volumes will be a worst case level. It is recommended
that parking be restricted on both Phase 5 street
intersections with Lemay Avenue at least 50 feet from
Lemay Avenue.
- The streets that are proposed to be 28 feet are cul-de-
sacs with the exception of the Phase 5 streets. The
wPhase
5 area will be provided with ample off-street
z
parking. This, along with the intersect"ion' parking- '__
z
restriction, will allow acceptable, safe operation on the
W
Phase 5 streets.
a
>
- This is primarily a large lot development. The density
is considered to be medium (2.1 to 6.0 dwelling units per
=
z
acre). Based upon criteria in "Recommended Guidelines
c3
for Subdivision Streets, A Recommended Practice,"
W
¢
Institute of Transportation Engineers, 1984, the pavement
c
width should be 28-34 feet. The proposed 28 feet meets
a
z
this recommended practice.
- Typical developments with large lot sizes provide more
than four off-street parking spaces per dwelling unit.
3
;
A comparable development is the First Filing of Clarendon
W
U_
Hills. Based upon observation at various times on a
cc
number of days, the average number of vehicles parked on
�--
Hinsdale Drive in Clarendon Hills was 3 in a length of
Q
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
Hinsdale Drive to have been a 28 foot wide street with
no traffic or parking problems.
I recommend that the cul-de-sac streets and Phase 5 streets
in Fossil Ridge 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,
Cy
Matti,.�,w J. Delich, P.E.
