1. This column provides the
goal of the subdivision
named above. While it may
share a common theme
with the intent of the entire
LEED credit, it focuses
more on one aspect of the
credit, rather than the
whole.
1. This column lists the best
practices associated with
achieving the goal mentioned
in the adjacent left column.
Since achieving many
of these goals may
require changes to
zoning, streets design,
bus routes etc, this
column provides the
name of any agencies
or bodies that may
need to be involved in
the planning process in
an effort to expedite
completion of the
project.

Employing BPM Table
Credit 1: Walkability
Intent: To promote transportation efficiency, including reduced vehicle miles traveled. To promote walking by providing
safe, appealing, and comfortable street environments that support public health by reducing pedestrian injuries and encouraging
daily physical activity.
Goal
1. Reclaim alleys as walking
paths for pedestrians,
providing alternate routes
throughout a city’s center,
and promote connectivity.
A. Alley Revitalization
Associated Best
Practices
1. Increase lighting and
signage, giving the alleys
more of a “street” feeling.
