Grid Un-Locked - Week 4
The document outlines ten characteristics of walkability and emphasizes the importance of a connected street network to enhance urban mobility, highlighting various routes and grid configurations. It advocates for a comprehensive mobility plan that includes multi-modal transportation strategies and critiques current conventional planning processes. Additionally, it discusses the need for premium transit systems to support economic growth, environmental sustainability, and improved quality of life in Sarasota.

- 5. Ten Characteristics ofWalkability: 1) Interconnected web of streets (small blocks, frequent intersections) (C-) 2) Mixture of uses + high enough densities (B-, D) 3) Street trees (trees between the sidewalk and the travel lane) (C-) 4) Lower traffic volumes (B-) 5) High quality frontages (transparent, interesting facades, no parking in front) (B+, downtown, D, elsewhere) 6) On-street parking and more “friction” (B, D) 7) Narrower and fewer lanes with easy-to-cross intersections (B+,C-) 8) Shallow setback or no setback in the urban core, slightly larger in suburbs (A-, D) 9) Sidewalks + properly designed bike lanes (C, F) 10)Two-way streets (A+)

- 79. Traffic Studies/ ConventionalPlanning and Approvals Process: Traffic Study costs $$ in order to determine how much is paid to the City, then $$ are paid to the City/County. Public hopes that the City/County spends it wisely. Mobility Fee and New Urbanist Planning and Approvals Process: $$$$ are paid to the City/County towards implementation of Premium Transit/Mobility/Multi-modal Plan, authored by the public and a qualified planner/mobility consultant with CNU credentials.* *City receives $$ more this way than the conventional way, but it needs to have an excellent transit/mobility plan in place.
- 80. Praise for thecurrent plan: Modified the inter-local agreement in order to allow for the City to spend funds collected from developers on projects that benefit the City and on projects that are multi-modal rather than just asphalt. Constructive criticism for the current plan: Pages and pages of confusing fee schedules based upon Euclidean uses could be replaced with a one sentence, lean, form-based fee schedule that does not consider use: “Impact fee is equivalent to one dollar per buildable square foot of the lot-of-record/parcel plus one dollar per built square foot.”
- 81. Why a PremiumTransit Network? • Retain creative class, youngsters, millennials, and those who due to age and physical limitations cannot drive. • Fixed-guideway systems promote compact growth and generate enormous tax revenue for municipalities and counties compared with lower-grade transit investments. • GHG/pollutant reduction = air quality and climate change mitigation • Reduce parking demand at origin/destination points, thereby increasing wealth for developers, purchasers, and renters. • Essential to affordability, as costs of operating and owning multiple cars can consume up to 1/3 of household budgets. • Reduce demand for costly auto-centric infrastructure paid for by tax payers (i.e. parking garages, road widening, and parking lots). • Reduced auto congestion along certain routes, or at least accept congestion and give people an alternative to it. • Walking+biking+transit culture and urbanism improve health.
- 82. Minimum Standards ina CNU/Smart Growth Mobility Plan • Modal Heirarchy Statement • Modal Spread vs. Modal Shift • Repeal L.O.S. as a measurement tool, replace it with VMT reduction • Missing segment study (Complete-the-grid Connectivity Master Plan) • GHG Mitigation Strategy • Sea-Level Rise Adaptation Strategy • Premium Transit Master Plan and Phasing Strategy with an emphasis on low-emissions vehicles such as electric rail and true BRT • T.O.D. Master Plan that coordinates land use @ station areas thereby boosting ridership and increasing profitability of the system/reducing need for subsidy
- 83. Minimum Standards ina CNU/Smart Growth Mobility Plan • Next Generation Bicycle Plan that emphasizes protected bike lanes, protected intersections, bike boxes, priority signalization, vision zero…but…which also acknowledges conventional bike lanes, sharrows, and M.U.R.T.s as tools in the toolbox • Bike Share Program • Multi-modal transfer optimization: Airport/Rail/Bus/Car Rental/Uber and Train Station/Bike/Ped and Water Taxi/Automobile/Bike Nodes • Zip car stations, Citywide Electric Car Charging network. • Transit frequency and convenience: low headway + dignified shelters
- 84. Financing and Implementingthe Mobility Plan • Overcome the City-held belief that only the County should provide transit and start dedicating general revenue $$ • Stop spending tens of millions of $$$ on parking garages • Divert hundred of millions of $$$$ from diverging diamonds and road widening to transit projects that have a greater economic and quality of life R.O.I. (requires vision plan to convince FDOT and County) • Density Bonus in exchange for premium transit contribution $$$ • Fare collection (seamless ticketing and transfers) $$ • 10% local seed money to obtain 90% federal match $$$ • T.I.F.F. + T.O.D. $$$$ • TIGER Discretionary Grants (DOT) $$$ • Gas Tax $$$ • Colleges Transit Surtax $ • Restructure Parkin In-lieu-of fund to benefit transit$ • City bonds $$$$ • Carbon credits $
- 85. Non-solutions for theshort term: • pedestrian overpasses • road widening, addition of turning lanes and travel lanes • conventional bike lanes • speed bumps and chicanes Long term traps: • encouraging car use by constructing more municipal parking garages • subsidizing car use by constructing diverging diamonds and other freeway ‘improvements’ • expecting autonomous vehicles to make transit obsolete
