SUSTAINABLE PURPOSE AND INTENT

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 COMMERCIALDESIGN 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.”

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.”
