WALNUT AVE. BIKE LANES
In response to a previous request from Nelson School and the Nelson P.T.O. and at the
direction from the City Council, staff has restudied the requested bike lanes on
Walnut Ave.
The A.Y.S.O. has been contacted regarding the on-street bike lane and proposed
removal of on-street parking and they have responded with no objections to the
parking removal. At a subsequent meeting with the school and P.T.O. they revealed
concerns about the conflict of the vehicular right turn movements from Walnut Ave. to
Browning Ave. and the cyclists. The proposed bike lane would disappear as it
approached the intersection to provide for the vehicular right turn movement, leaving
the cyclist without a designated lane. The school and P.T.O. did not indicate any
opposition to the removal of parking along Walnut Ave.
An alternative solution was discussed for the westbound bike lane between Walnut~'
Ave. and the railroad tracks. This alternate consisted of an off-street
bike/pedestrian lane adjacent to the inside of the chain link fence for a distance of
approximately 365± ft. westerly of the railroad tracks to an existing opening in the
fence and then continuing in a northeasterly direction for a distance of approximtely
125'5 ft to the asphalt surfaced play area. This alternate is shown in red on the
attached aerial photo. The cost for this alternate is as follows:
8 foot wide 4" Thick P.C.C. Bike/Pedestrian Lane ................ $7840.00*
8 foot wide 0.3' Thick Asphaltic Concrete Bike/Pedestrian Lane--$7690.O0
* In the event this alternate is selected, it is suggested that the Portland Cement
concrete be utilized in lieu of the asphaltic concrete material due to the potential
savings in future maintenance.
It appears that the on-street bike lane would still be required in addition to the
off-street facility. This on-street facility would be used by other cyclists rather
than just students attending Nelson, therefore, it would not be feasible to
discontinue the westbound on-stmeet bike lane westerly of the tracks.
The installation of the off-street facility would eliminate the conflict of vehicular
-right turns and student cyclists at the northeasterly corner of Walnut and Browning
Avenues. However, the installation of this type of facility by the City could set a
precedent for similar projects at other school sites.
Funding for this project is not available during this fiscal year. A special
appropriation is not feasible or recommended at this time in that recent Council
policy requires five affirmative votes on any special appropriation when the cash
reserves fall below a designated percentage of the annual budget and, at the present
time, the cash reserves are below the designated percentage.

A joint project between the school district and the City might be considered by both
agencies during the upcoming 1981-82 fiscal year.
Attached for your information is a copy of my previous memo dated February 5, 1981
and a sketch of the proposed widths of vehicular travel lanes and bike lanes for
Walnut Avenue.
RECOMMENDATION:
It is recommended that the Tustin City Council at their meeting of March 16, 1981,
approve the following:
Restripe westbound Walnut Ave. for two 1i' wide travel lanes between
Cherrywood Lane and Red Hill Ave.
Stripe a 5' wide bike lane for westbound Walnut Ave. between Raintree Rd.
and Browning Ave.
3. Restripe eastbound Walnut Avenue for two 11' wide travel lanes between
Oxford Ave. and Cherrywood Lane.
4. Stripe a 5' wide bike lane for eastbound Walnut Ave. between Browning'Ave.
and Raintree Rd.
5. Remove all on-street parking along Walnut Avenue between Red Hill Avenue and
Raintree Road.
No action on the "No Right Turn On Red" until such time the traffic signal
at Walnut and Browning Avenues is installed and operational for further
staff review.
In addition, it is recommended that the off-street facility be considered in the
lg81-82 Capital Improvement Program as a joint project with the school district.
Each agency would participate on a 50% basis.
