SUBJECT: ITEM 5M – INITIATION OF DETACHMENT APPLICATION TO MODIFY
CITY LIMIT BOUNDARY ON SLACK STREET
The following memorandum provides City staff responses, shown in italics, to questions
received from a Council member regarding the initiation of an application to modify the
City limit boundary on Slack Street. Staff determined it would be helpful to provide this
memo to all Council Members and the public, as the responses offer clarification
regarding the future street improvements proposed on Slack Street.
1) What are the anticipated impacts to Grand Avenue/Slack Street that would
result from the requested detachment?
The requested detachment itself is not anticipated to result in any substantive
impacts to the buildout of Slack Street or the Grand Avenue/Slack Street
intersection. The detachment will adjust the City Limit to the back of sidewalk to
define a clear delineation between the public street and Cal Poly’s private property,
once Cal Poly receives approval from the City Council at a future meeting to
abandon a portion of the Slack Street right-of-way. The housing project will include
frontage improvements that will widen Slack Street to City Engineering Standards,
including the addition of sidewalks and ADA-compliant curb ramp upgrades at the
northeast corner of the Grand/Slack intersection. The 25 feet of right-of-way
proposed for abandonment and detachment is not needed for buildout of Slack
Street or the future intersection to current engineering standards.
The City’s General Plan Circulation Element identifies future plans to reconstruct
the Grand/Slack intersection as a single-lane roundabout; however, this
improvement is not proposed as part of Cal Poly’s 33-unit housing development,
nor is there a clear City policy impact that would trigger the need to advance the
roundabout at this time. The intersection currently operates well within the City’s
traffic operations policy thresholds, there are no reported collisions at this
intersection in the past five-year period, and this intersection has not been
identified as a high-collision location in the City’s past Traffic Safety Reports. The
Cal Poly housing development site plan has been designed to ensure that
adequate setbacks are provided as to not preclude future construction of a
roundabout.

While not part of the housing development or related frontage improvements, it
should be noted that the City has plans to advance complete street improvements
on Grand Avenue as part of the 2024 Roadway Sealing project, if favorable bids
are received within budget. Planned improvements include striping revisions,
protected bike lanes, pedestrian median refuges, and corner radius tightening at
the Grand/Slack intersection, designed with the intent to reduce exposure and
improve comfort for pedestrians and cyclists crossing the Grand/Slack
intersection. While Cal Poly is not constructing these improvements, the university
has issued an encroachment permit to allow the City to install the portions of these
intersection improvements that overlap with current Cal Poly right-of-way.
2) The west side of Slack Street (across Grand) appears to be similar to what is
being proposed on the east side (similar sidewalk width, drive-lane width,
parking on south side but not the north Cal Poly side). Is this correct?
Improvements to the east side of Slack Street in front of the Vista Meadows faculty
housing project would include two 10-foot travel lanes, a 5-foot sidewalk with 4-
foot landscaped parkway, along with curb and gutter. Existing on-street parking
would remain on the south side of Slack Street. Overhead utilities on the northerly
frontage would be undergrounded within the public improvements. The resulting
street width is 28 feet curb-to-curb.
In comparison, the existing segment of Slack Street west of Grand Avenue ranges
from approximately 40 to 47 feet curb-to-curb, and includes two 10-foot travel
lanes, a center turn lane (near Teach Elementary & Pacheco Way), on-street
parking on the south side of the street, and bike lanes in both directions.

3) Will Cal Poly be providing traffic calming on the east side of Slack to contain
the speeds of vehicular traffic, similar to what was needed on the west side
across Grand?
Traffic calming (speed humps) was installed on Slack Street west of Grand Avenue
several years ago in conjunction with a City-led Neighborhood Traffic Management
(NTM) project, in response to an application filed by local residents requesting
measures to reduce illegal speeding near Teach Elementary School. The City has
not received any NTM applications for Slack Street east of Grand Avenue and Cal
Poly’s current frontage improvement plans do not include any proposed traffic
calming measures. The Slack Street width east of Grand Avenue will be 28 feet
curb-to-curb, 15-20 feet narrower than Slack Street west of Grand Avenue, which
generally invites less potential for illegal speeding. If the Council wishes to
preemptively address potential illegal speeding concerns, it would be within their
discretion to recommend a condition of approval requiring traffic calming features,
such as speed humps or other elements as approved by the City Public Works and
Fire Departments, to be included with Cal Poly’s public improvement plans on
Slack Street as a condition of detachment and right-of-way abandonment.
4) The initiation report identifies “next steps” in the process, including a
Planning Commission hearing and then an additional hearing at City
Council. Can Council request that this goes before the Active Transportation
Committee (ATC) as well?
It is certainly within the Council’s discretion to direct staff to take this item to the
City’s Active Transportation Committee for consideration. This was not originally
planned, as the proposed action (revision of City Limit and future right-of-way
abandonment) does not appear to include any Active Transportation project or
policy implications that would typically fall under the purview of the ATC. The City’s
adopted Active Transportation Plan identifies the existing bike lanes on Slack
Street west of Grand Avenue to remain and calls for protected bike lanes on Grand
Avenue as a future Tier 2 (moderate priority) project, which are being partially
implemented as part of the 2024 Roadway Sealing project referenced above. The
Active Transportation Plan does not identify any specific pedestrian or bicycle
improvements projects on Slack Street east of Grand or at the Grand/Slack
intersection itself. As currently proposed, Cal Poly’s housing development and
related frontage improvements would not appear to conflict with any adopted City
plans or policies related to active transportation.
As a point of clarification, the City’s involvement with the 33-unit Vista Meadows
faculty housing development is only related to the right-of-way and City limit line.
Cal Poly must obtain an encroachment permit through the City to install
improvements in the right-of-way. The requests for modification of the City limit
line and abandonment of 25-feet of unused right-of-way are discretionary
applications that can include conditions of approval; however, the City’s purview is
limited to only the right-of-way itself. California State University is the lead agency
Item 5m. Initiation of Detachment Application to modify City limit boundary on Slack Street Page 4
for the environmental review, entitlements, and permits for the 33 housing units
and onsite improvements. Based on the environmental review completed by Cal
Poly (https://afd.calpoly.edu/facilities/planning-capital-projects/ceqa/), the project
will be adding 18 peak hour trips to the Slack/Grand intersection. The 33 units at
Vista Meadows do not trigger installation of the Slack/Grand roundabout at this
time based on CEQA; however, future build out on the Cal Poly campus could
trigger roundabout construction in the future. While the Slack/Grand roundabout
is identified in the City’s General Plan Circulation Element, there is no current
funding for construction of the roundabout. As a superior agency constructing
housing outside of the City’s jurisdiction, Cal Poly will not be contributing to the
City’s TIF program and is not required to pay impact fees towards funding the
Slack/Grand roundabout.
