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 VACANT &PARKING LOTS
DOWNTOWN TUCSON
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 GREEN SPACE
DOWNTOWN TUCSON
The goal of this analysis was to identify parcels which will be converted to green spaces to encourage walkability in the study area
Encouraging walkability
OBJECTIVES GOAL
Identify parcels which will be converted to green spaces to encourage walkability. 1:Identify land suitable for open spaces/ parks 1.1: Identify vacant parcels
SUB-OBJECTIVES
1.2: Identify parking parcels 1.3: Identify low slope under 5%
2:Identify walkable/ accessible areas suitable for open spaces
2.1: At least around 1/8 of a mile away from “commercial-office” land use. 2.2: At least around 1/8 of a mile away from “entertainment” land use 2.3: At least around 1/8 of a mile away from “industrial” land use. 2.4: At least around 1/8 of a mile away from “institutional” land use. 2.5: At least around 1/8 of a mile away from “mixed-use” land use. 2.6: At least around 1/8 of a mile away from “recreational” land use. 2.7: At least around 1/8 of a mile away from “residential” land use. 2.8: At least around 1/8 of a mile away from “retail” land use. 2.9: At least around 1/8 of a mile away from “services” land use. 2.10: At least around 1/8 of a mile away from “modern street car stops”. 2.11: Closer to “modern street car route”. 2.12: At least around 1/8 of a mile away from “bus stops”. 2.13: Closer to “bus routes”.
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)
MUA = Objective 1
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
Weighted Overlay from public input
Suitability analysis
Rate the importance (%) of having a green space at a walkable distance from_____, so all the values add 100.
Commercial_Office Entertainment Industrial Institutional Mixed Use Modern S Car (route) Modern S Car (stops) Bus routes Bus stops Recreational Residential Retail_Sales Services

MUA = Objective 1 + MUA = Objective 2
FINAL SUITABILITY
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.
