ntersect on of Old Pomerado Road and Pomerado Road. Shou d Stowe Drive not be
extended, a traffic signal would be warranted in the future at the int of Old
Pomerado Road and Pomerado Road.
Staff has prepared preliminary desi n based on current survey and development plans of
vacant parcel and has raised severa safety issues regarding the roadway. Staff
requests approval from the Council o arrange a neighborhood meeting to discuss the
current preliminary design of the S owe Drive extension and discuss alternatives to the

BACKGROUND
On Ju e 11, 1992, the City Council and the Redev lopment Agency held a
works Dp to discus several issues relative to t e Old Pomerado Road
neigh or'oDd. At hat meeting the C uncil and t e Agency approv d the project
to ex en Stowe Dr ve from Pomerado Dad to Old omerado Road. he approval
was base on a pre iminary design wh ch included a reliminar a ignment and a
descript on of the roadway. The fda w y varied fro a slope f % near
Pomerado Road to 15% with a substa dar roadway of 4 feet wi e. Staff also
indicated t e design would be coot ina ed with the evelopmen of the vacant
land west o Pomerado Road. $400, O0 as been budgeted from he Redevelopment
Agency for he extension of Stowe rive. Staff has begun the design by
completing he preliminary survey.
At that orkshop, st ff presented th traffic s gnal analysis at the
intersec ion of Old omerado Road an Pomerado Dad. Should Stowe Drive not
be exten ed, a traff c signal would e warrante in the future at the
intersec ion of Old omerado Road an Pomerado Dad.
FINDINGS
Staff has completed the survey a d has begun the preliminary alignment design
for the Stowe Drive ased on this more detailed survey and design
analysis, staff has identified s gnificant issues relative to the design of
the Stowe Drive The ssues include the following:

1. To accommodate from the vacnt land to St we Drive
from the undeveloped properties, a port on of the roa way must be
con ructed with the slope not to excee 6%. By cre ing a
sec on of roadway with a 6% section, t e slopes on e remaining
sec ons of the roadway exceed the City standard of %. A
por on of the roadway would have a vertical slope o 17.6% (see
Attachments I and 2).
2. Based on the vertical curvature and the horizontal of
the roadway as proposed, the design speed would equate to 20
mph. Based on the steepness of this roadway, we believe it
would be very difficult for drivers to maintain a speed of 20
mph.
3. The lower portion of the roadway which has a 15% sloe
terminates with a short landing of a 6% slope roadwa at a T-
This section of roadway also has a ho izontal
curve which, under further analysis, staff finds to e a
substandard and unsafe design.
4. The width of the roadway as proposed is 24 feet wide. For a
low -olume rural residential roadway, a 24 foot wide roadway
may e acceptable. Based on the horizontal and vertical curves
and he volume of the roadway which may exceed 1,000 vehicles
per ay, staff believes the roadway would be safer at the
City s standard width of 36 feet.
5. To widen the roadway to the City standard of a minimum 36 foot
wide roadway in a 54 foot wide right-of-way would require the
taking of more property and potentially impacting adjoining
other
6. Existing resi ential roperties on the north side th t use this
corridor as t eir dri eways will have to connect the r
driveways to towe Dr ve in a section of roadway tha
approaches 15 which s an undesirable location for riveways.
7. Th budget was based on the removal of the Big Stone Lodge
of ice building during the construction of the road ay. This
bu lding is now a residential unit which will add a ditional
re ocation costs to the project budget. Widening t e roadway
may require additional cost by causing damages to o her
properties.

8. Constructing the Stowe Drive extension as proposed will'
concentrate drainage to Old Pomerado Road. Staff anticipated
collecting the drainage from the roadway and disch rging it to
the creek; however, with the detailed design, staf has
determined that additional drainage will be collec ed on this
roadway from the vacant properties which will requ re increased
drainage costs.
Based on a better understanding of the development lans of the adjoining
property; a more detailed survey; and preliminary d sign analysis, staff
believes that the current alignment of the Stowe Dr ve will create a
ubstandard un af roadway as well as increased pro ect costs. Staff has
etermined tha w thout the of Stowe Driv , a traffic signal would
e warranted a 0 d Pomerado Road and Pomerado Road. Staff re uests approval
rom the Counc 1 o arrange a neig'borho d meeting to discuss he current
preliminary desi n of the Stowe Dr ye and discuss al ernatives to
the proposed des gn such as replac ng h s project with a traf ic signal at
