Is there consensus about what constitutes a comprehensive plan?
No.
What two acts is the comprehensive plan rooted in?
- SZEA (1926) - The Standard Zoning Enabling Act
- SCPEA (1928) - The Standard City Planning Enabling Act
What does the SZEA (1926) - The Standard Zoning Enabling Act state about comprehensive plans?
SZEA states that zoning regulations must be “in conformance with a comprehensive plan” but did not define the term.
What does the SCPEA (1928) - The Standard City Planning Enabling Act state about comprehensive plans?
SCPEA purposely avoided defining the comprehensive plan but gives examples of the subject matter. It’s vague and differs by state.
What is the bottom-line message of PAS QuickNotes 54 regarding The Value of Planning?
Comprehensive planning is important to do for economic, environmental and social reasons. If you don’t have a comprehensive plan, much of what you do is reactive.
This QuickNotes articulates what the benefit of comprehensive planning actually is. “Plans based on the best available information and the most inclusive processes…far outweigh the investment of resources in the planning process.”
Why did the two acts from the 1920’s cause confusion about comprehensive planning?
SZEA and SCPEA don’t provide a definition for what a “comprehensive plan” is.

What is a Traffic Analysis Zone (TAZ)?
Used in mathematical traffic/transportation planning model.
TAZ is the area to be studied, divided into zones. Each zone is identified as producing or attracting trips. Defined by Census Bureau/data.
Very similar to Census tracts. Might be used in employment projections - tabulating traffic-related data–especially journey-to-work and place-of-work statistics
What is Trip Distribution?
Trip distribution refers to the number of trips originating and ending at place to place.
the estimation of the # of vehicles that travel from one location to another.
Eg. you are considering how to create an appropriate mix of land uses that would result in appropriate movement across the subarea. As part of this study, you need to understand how many vehicles will travel from one particular place to another place.
What is a Travel Demand Model?
Travel demand models use current travel behavior to predict future travel patterns from a sample of travel behavior data. These are a critical tool for planners who use them to forecast the transportation needs of the communities they serve (predicts travel demand).
Includes 4 steps.
What are the 4 steps of the Travel Demand Model?
- Trip generation (volume of trip origins and destinations)
- Trip distribution (across TAZs)

Non-work trips add to congestion.
What is a Traffic Calming and Traffic Safety Investigation?
An evaluation conducted by the DOT that responds to citizen concerns like traffic speed, volume, and type, and aggressive driving behaviors.
Assessments are performed within defined geographic areas like blocks. Outcomes of this investigation may include a reduction in traffic speed or improved general safety for pedestrians and bicyclists.
What is a bulb-out/”neck-down”?
(traffic calming tool)
A curb extension! Usually at an intersection, that narrows the vehicular pathway to inhibit fast turns and shorten the crossing distance for pedestrians.
Like the annoying ones they have in Allegheny Commons
What is a chicane?
(traffic calming tool)
A series of fixed objects, usually extensions of the curb, which alter a straight roadway into a zigzag or serpentine path to slow vehicles.
What is a choker/”mid-block crossing”?
(traffic calming tool)
A narrowing of a fixed street, often in the middle of a block or near an intersection. A choker can be done with curb extensions, landscaping, or islands in the street.
Chokers are curb extensions that narrow a street by widening the sidewalks or planting strips, effectively creating a pinch point along the street.
Narrowing of the main road section is referred to as a “choke” or “mid-block crossing.”

Techniques that narrow points along the roadway so that drivers are forced to slow to negotiate the narrowed points.
What is the difference between a choker/mid-block crossing and a neck-down/bulb-out?
a “choke” or “mid-block crossing” narrowing of the MAIN ROAD SECTION while a “neck-down” or “bulb-out” narrows at an intersection.
The purpose fo both is to shorten pedestrian crossing distances and slow car traffic turning at intersections.
Traffic calming methods that improve pedestrian safety.
Does traffic calming involve getting rid of on-street parking?
No, on-street parking contributes to traffic calming.
What is the difference between horizontal and vertical traffic calming?
Vertical traffic calming refers to things like raised intersections and speed bumps.
Horizontal traffic calming refers to horizontal shifts like traffic circles. A horizontal deflection hinders the ability of a motorist to drive in a straight line by creating a horizontal shift in the roadway.

APA labeled this act a “mixed bag.”
It allows cities and metropolitan areas to set their own street design standards for projects that are federally funded, but the APA was unhappy that it didn’t raise the gas tax in order to fund transportation improvements.
When was the gas tax last raised?
1993
APA is in favor of __________. People who use the highways should fund the improvements rather than generalizing it to the whole population.
user funding
What Transportation Act was first to present a multi-modal approach to transportation?
The Intermodal Surface Transportation Efficiency Act of 1991 (“Ice-Tea”)
Why did APA label the FAST Act a “mixed bag”?

- Advance opportunity for all
- Embrace and support innovation
- Make communities safer and more resilient
What are 4 things that planners need to consider when thinking about demands for infrastructure development?
- Typical demand
- Demand under worst case scenario (eg. fire or drought)
- How will roadways be used in worst case scenario?
- Sewer facilities and capacity - what is the depth and velocity of flow

Planners would consider:
-Fire insurance ratings
-Distance between the fire station and the development
-Water pressure/availability
What 4 things should green infrastructure be?
- Cost effective
- Integrated with gray infrastructure
- Multifunctional (benefit flood control, reduce dependence on oil, and improve public health outcomes)
- Lessen heat island effects
What is gray infrastructure?
Gray infrastructure refers to structures such as dams, seawalls, roads, pipes, gutters, drains, dykes, levees, or water treatment plants.
Historically, we use this gray human-engineered infrastructure for water resources such as water and wastewater treatment plants, pipelines, and reservoirs.
Through massive feats of engineering, stormwater is directed away from certain locations and toward others. These change nature’s natural processes.
Grey infrastructure typically refers to components of a centralized approach to water management.
What is green infrastructure and examples of it?
Green infrastructure mimics nature and captures rainwater where it falls.
Can include permeable pavement, rain gardens, bioretention cells (or bioswales), vegetative swales, infiltration trenches, green roofs, planter boxes, rainwater harvesting (rain barrels or cisterns), rooftop (downspout) disconnection, urban tree canopies/a row of trees along a major city street, greening an alleyway, acres of open park space outside a city center, or constructing a wetland near a residential housing complex.
What is the difference between gray and green infrastructure?
Both are related to water management. Gray infrastructure is what we historically use for stormwater management to move it from one place to another. Green infrastructure mimics nature and more cost effectively manages stormwater.
A Yale School of Forestry & Environmental Studies report on the Philippines concluded that in almost all scenarios, green infrastructure is more cost-effective than gray.
Why is green infrastructure important?
Stormwater runoff is a major cause of water pollution in urban areas. It carries trash, bacteria, heavy metals, and other pollutants through storm sewers into local waterways.
Heavy rainstorms can also cause flooding that damages property and infrastructure.
What is the Telecommunications Act of 1996?
A historic change in the US law governing communications that was enacted to ensure that advanced telecommunications are available to everybody - a policy of universal service.
The FCC and the states are the regulatory bodies and implement this law.
This act preempts local regulation of cell tower radio frequency emission effects, but requires zoning decisions be in writing and supported by substantial evidence.
What are the 3 take aways from the Planning and Broadband PAS report?
Planners should be considerate of:
1. Production - efficiencies can reduce use of raw materials and energy
2. Consumption - consume less by replacing products with virtual goods
3. By-Products - monitor and manage the waste stream to reduce pollutants and reuse by-products of broadband communications
How do planners determine sewer capacity?
- Depth of flow
- Velocity of flow

What are FEMA’s Local Mitigation Plans?
These are plans that have been required since 2000 that plan is supposed to address issues of disaster mitigation.
Supposed to be updated every 5 years.
Includes a list of natural hazard mitigation actions that the community is intending to take (eg. how they will change building codes, restore natural function of a floodplain, etc..)
What are the two requirements of the National Flood Insurance Program of 1968?
- Required local governments to identify flood-prone areas.
- Required a link between identifying these flood-prone areas and the ability to buy flood insurance. Some people are required to buy flood insurance if they live in certain areas designated on a FEMA flood map.
How often are Local Mitigation Plans supposed to be updated?
Every 5 years.
What does the National Flood Insurance Program require local governments to do?
- Identify flood-prone areas
- Identify the link between living in a flood prone area and the ability to buy flood insurance.
What is non-point source pollution?
Results from land runoff, precipitation, drainage, seepage - may be associated with a particular land use.
Comes from many diffuse sources and covers a wide area. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.
defined to mean any source of water pollution that does not meet the legal definition of “point source”
What is point source pollution?
any single identifiable source of pollution from which pollutants are discharged.
discernible, confined and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, or vessel or other floating craft, from which pollutants are or may be discharged
Commonly from factories/industrial and sewage treatment plants.
EPA defines point source pollution as any contaminant that enters the environment from an easily identified and confined place. Eg. smokestacks, discharge pipes, and drainage ditches.
What are examples of non-point source pollution?
-Fertilizers, herbicides, and insecticides contain nitrates and phosphates (turns water green with algae)
-Oil, grease and toxic chemicals from urban runoff and energy production
-Bacteria and nutrients from livestock, pet wastes and faulty septic systems
-Salt from irrigation practices and acid drainage from abandoned mines
