Implement Policy 1.2-l of the Plan.
Encourage sustainable development.
Improve standards for walkable development.
Establish connectivity standards for pedestrians, bicyclers, mass
transit and automobiles.
Reduce traffic on arterials and collectors.
Encourage the creation of development that has a sense of place.”
Minimize adverse impacts of automobile traffic patterns and
commercial development on existing adjacent residential
communities.
TDD COMMERCIAL
DESIGN OBJECTIVES
“a. Public spaces, such as plazas and
squares, integrated within commercial
development providing places for
people to gather or rest…..
b. Parking is provided on-street, behind
buildings, and in shared parking lots.
Parking lots in front of buildings create
barriers between pedestrians and
storefronts and shall be discouraged.
c. Buildings are human scaled in design
with a range of architectural features,
which create an attractive and varied
streetscape. Building frontages shall be
set near the sidewalk and building sizes
are generally consistent, providing a
sense of enclosure for the street, except
where separations are permitted.
Architectural detailing and applied
decoration enliven facades and add
texture. Building entrances and
windows shall be located along street
frontages to break up blank walls and
enhance the pedestrian environment.”
TMD PURPOSE
“1. Provide a concentrated area for
shopping, entertainment, business,
services and cultural opportunities by
allowing a mix of commercial and
institutional uses and establishing
physical development and design
standards that create pedestrian
oriented development.
2. Provide housing opportunities through
vertically integrated residential uses.
3. Promote a mix of uses in a manner that
creates a stronger pedestrian
orientation through design, placement
and organization of buildings, plazas,
common public space, and dispersed
parking.
4. Ensure traditional marketplaces are
compatible with the overall design
objectives of the Plan and MGTS.”

WALKABLE COMMUNITIES
12 STEP PEDESTRIAN
AND BICYCLE PROGRAM
1.
Provide Continuously Linked
Walkways.
2. Pedestrian Intersections.
3. Americans with Disabilities Act
(ADA)
4. Signal Placement.
5. Illumination.
6. Simplify Median Crossings.
7. Schools.
8. Eliminate Backing.
9. Access Management.
10. Auto Restricted Zones and Parking
Restricted Zones.
11. Combine Walking with Transit.
12. Walkable Land Use Planning.
1. PROVIDE
CONTINUOUSLY LINKED
WALKWAYS
Accommodate the elderly,
handicapped, children and those
who chose or desire to walk.
Recommends a minimum 6’ to 7’
separation from roadways.
Provide street trees to buffer
pedestrians from adjacent
vehicular traffic.
Include landscaping, benches,
trash receptacles and other
pedestrian amenities.
Street furniture and other
obstacles shall not impede mobility
and access.
- Provide a 50/50 ratio of pedestrian
realm to automobile use areas for
maximum economic development.
-
2. PEDESTRIAN
INTERSECTIONS
-
-
-
Provide street crossings which
accommodate the physical abilities
of pedestrians.
Maximum crossing width should
be 48’.
Roadway geometry to dictate
turning speed *.
* Note: Oftentimes turning radius
is dictated by truck or fire
rescue vehicular access. This
does not preclude the use of
defined pedestrian areas, with a
transitional marked zone to
discourage high speed turns.
6. Simplify Median
Crossings.
-
Additional pedestrian crossing
areas can be created mid-block
thru the use of raised medians
designed expressly for
pedestrian crossings.
12. Walkable Land
Use Planning.
“New and “in-fill land use
development should favor walking
over driving. Traditional
Neighborhood Design (TND), grid,
Planned Mixed Unit Development
(PMUD) roadway systems, Transit
Oriented Development Design (TOD),
neighborhood schools, pocket parks,
and neighborhood stores should
predominate land use codes,
ordinances and regulations. Places
to sit should be provided on retail
blocks and along corridors where
people walk through their
communities. Businesses should
front on sidewalks with parking
located alongside or behind stores.
Shared use parking lots should be
emphasized wherever possible.”
