LUT-7
A project that is designed around an existing or planned transit, bicycle,
or pedestrian corridor encourages alternative mode use. For this
measure, the project is oriented towards a planned or existing transit,
bicycle, or pedestrian corridor. Recommended Guidance for Land Use
Emission Reductions attributes 0.5% reduction for a project oriented
towards an existing corridor.
MBI Justification: The Project site and expansion supports the use of
bicycle and pedestrian activity. Sidewalks are provided adjacent to and
onto the site. A trail exists along the property that connects Breck
Street to Iris Street. The project proposes to maintain the high level of
bicycle and pedestrian accommodation.
Additional Justification: Existing bike/pedestrian paths have direct
connections to and through campus.

Roadways will be designed to reduce motor vehicle speeds and
encourage pedestrian and bicycle trips with traffic calming features.
Traffic calming features may include: marked crosswalks, count-down
signal timers, curb extensions, speed tables, raised crosswalks, raised
intersections, median islands, tight corner radii, roundabouts or mini-
circles, on-street parking, planter strips with street trees,
chicanes/chokers, and others.

MBI Justification: Bicycle lanes currently existing along Johnson
Avenue. Bicycle accommodations on-site are provided via the shared
travel ways and the trail that extends through the site from Breck
Street to Iris Street. The expansion traffic will benefit from this
condition.
Additional Justification: 100% of streets and intersections around
campus have traffic calming features:
Johnson: Dedicated bike lane.
Ella: On-street parking.
Iris & Breck: No through traffic.
Johnson & Ella intersection: Countdown signal timers, marked
crosswalks.

Providing bicycle parking is anticipated to result in a 0.625%
reduction in VMT for non-residential projects.
JUSTIFICATION: The existing hospital site provides dedicated bicycle
parking on-site. The proposed expansion project will provide additional
bicycle parking.

end-of-trip" facilities for bicycle riders including showers, secure
bicycle lockers, and changing spaces.
Based on the CCAP guidebook, the TIAX report allots 2.5% reduction for
all bicycle-related measures and a 1/4 of that for this measure alone.

Increasing transit service frequency/speed is projected to result in
a 0.02% - 2.5% reduction in VMT.
MBI Justification: This type of measure requires regional or local
agency implementation and coordination to provide transit beyond
what is currently available and thus it is not applicable for individual
development projects.

Providing employee parking cash-out programs is anticipated to result
0.6% - 7.7% commute VMT reduction.
MBI Justification: This strategy allows the employer to provide
employees with a choice of forgoing subsidized/ free parking for a cash
payment equivalent to the cost of the parking space. Potential VMT
reduction values are based on jurisdictional size.

Implementing a car-sharing program is projected to result in a
0.4% - 0.7% reduction in VMT.
MBI Justification: The nature of the project would be a candidate for a
car-sharing program between employees that work the same shift.
However, this type of measure requires private market support as well
as regional or local agency implementation and coordination. Thus, it is
not applicable for individual development projects unless an
established program is in place.

Telecommuting programs are employment-based strategies.
MBI Justification: Given the service nature of the hospital,
telecommuting options would be limited to administrative tasks such
as billing or scheduling, which would have limited impact.

Implementing employment-based ride-sharing strategies is
projected to result in a 1% - 15% commute VMT reduction.
MBI Justification: CAPCOA page 253 (TRT-11 and TRT-12) indicates
that a low range % VMT reduction would occur with a low
implementation/small employer while a high range % VMT reduction
would occur with a high implementation/large employer.
Ride-sharing programs work best in conditions where work schedules
are fixed and regular. Swapping shifts and the requirement for doctors
to visit admitted patients at various times would limit the VMT
reduction. While some benefit from a ride-sharing program can get
anticipated, the nature and locale would likely result in a lower level of
VMT reduction.
Additional Justification: Doctors make up a small percentage of staff.
The vast majority of the staff are in administrative and nursing areas
have fixed/regular hours and benefit from ride-sharing strategies. A
portion of the existing employees utilize an employment-based ride-
sharing program. The hospital is a larger scale employer.

Implementing Commute Trip Reduction Marketing is projected to result
in a 4% - 5% reduction in commute vehicle trips with full-scale
employer support.
MBI Justification: Implementing commute trip reduction
strategies without a complementary marketing effort results in a
lower VMT reduction.

Additional Justification: In addition to the SLO Rideshare program
marketing efforts, the hospital’s existing Trip Reduction Management
Program includes a Ride-Share bulletin, a Transportation Coordinator

Increasing the mix of uses within a project could result in a 9% -

The project should minimize the need for external trips by including
services/facilities for day care, banking/ATM, restaurants, vehicle
refueling, and shopping.

the on-site cafeteria and gift shop reducing the need for external trips
by staff and visitors. Half of the low range of VMT reduction was
