walkability and green spaces
DESCRIPTION
In downtown Tucson, AZ. A walkable environment could be provided by adding green networks.TRANSCRIPT
WALKABILITY AND GREEN SPACES Downtown Tucson
Julio Carrillo Baran Farahani Katharine Mitchell LAR622 – December 6, 2011
Study Area This area is 788.3 Acres and was chosen due to the fact that the new Modern streetcar route will be running through, and this part of Tucson is more compact than other parts, such as east Tucson.
PROBLEM DOWNTOWN
TUCSON VACANT &PARKING
LOTS
The study area also currently has a large number of vacant lots not currently being used. The negative impacts of these vacant parcels include: - an aesthetic eyesore - encourage crime in the vicinity or on the lot itself - the city is missing out on the potential to attract businesses - create low activity clusters
GOAL
DOWNTOWN TUCSON GREEN SPACE
The goal of this analysis was to identify parcels which will be converted to green spaces to encourage walkability in the study area

2.10: At least around 1/8 of a mile away from “modern street car stops”.
Identify parcels which will be converted to green spaces to encourage walkability.

SUITABILITY ANALYSIS
Our methods: • LUCIS : Land Use Conflict Identification Strategy • “Paired Method” (survey) Defining weights • Zonal statistics Averaging land suitability to
parcel suitability.
Objective 1 : Identify land suitable for open spaces /parks
- Sub-objective 1.1 : Identify vacant parcels.
Objective 1 : Identify land suitable for open spaces /parks – Sub-objective 1.3 : Identify
low slope areas (under 5% rise)
Objective 2 : Identify walkable/accessible areas suitable for open spaces /park Sub-objective 2.1: At least
around 1/8 of a mile away from “commercial – office” land use.
Objective 2 : Identify walkable/accessible areas suitable for open spaces /park Sub-objective 2.11: Closer to
“modern street car route”.
Objective 2 : Identify walkable/accessible areas suitable for open spaces /park Sub-objective 2.12: At least
around 1/8 of a mile away from “MSCar stops”.
Goal: Identify parcels which will be converted to green spaces to encourage walkability. Objective 2 : Identify walkable/accessible areas suitable for open
spaces /parks

Rate the importance (%) of having a green space at a walkable distance from_____, so all the values add 100.
FINAL SUITABILITY 1. Applying Zonal Statistics • Identify average suitability
per parcel • Useful tool for city
planners to identify potential parcel conversion to green spaces
FINAL SUITABILITY 2. Identifying potential
network connections • Useful tool for designers
to evaluate creation of WALKABLE ROUTES
FINAL SUITABILITY 2. Identifying potential
network connections • Useful tool for designers
to evaluate creation of WALKABLE ROUTES
POTENTIAL OUTCOMES AND BENEFITS
Walkable networks provide: • Transportation efficiency. • Reduction of VMT. • Encourages daily physical
activities.
