Factors influencing 19th century development
Industrialization, immigration, population increase, urbanization
Eminent Domain
The right of the government to seize private property for public use
Greensward plan for central park
Olmsted, Vaux, 1858, Eminent domain used in Manhattan to create a public park

City-Beautiful movement
1897-1909, response to industrialization and urbanization
Focus:
Civic beautification and aesthetic responses
physical strategies to address larger social issues
Monumental planning
neoclassical architecture
Civic centers
wide boulevards
Ebenezer Howard
Author of Garden Cities of Tomorrow (1902), launches garden cities movement
Garden Cities Movement
Self sustaining communities with residential, commercial, industrial
Surrounded by agriculture and recreational greenbelt
Population no greater than 32,000 on 6000 acres
Best of town and country
Garden Suburbs
planned residential communities designed in park-like settings, Tugwell and Stein, blending garden cities with suburban living
Radburn NJ
Garden suburb example, 1928
Pedestrian overpasses and underpasses
Garden style apartments
First Comprehensive Plan
Chicago Plan of 1909, designed by Daniel Burnham
Seven key elements:
System of regional highways
Systematic arrangement of streets
Improvement of railroad terminals
Build new docks on chicago river
Improved lake michigan frontage
Extend park system
Create civic centers
Zoning Ordinance
Translates policy to specific requirements on zones and permitted uses for individual landowners
Aspects of a General Plan
Geographical coverage (state, region, county, city, community)
Subject matter (8 elements)
Time frame (10-20 years with four amendments allowed)
Participation and Process
Mandate vs legal enforcement power
California mandates every county and city adopts a general plan but cannot legally enforce it
Four major objectives of general plans
Identify goals (land use, housing circulation, environmental, etc)
Provide a basis for local government decision making, decisions on development approvals
Inform (citizens, developers, decision makers, other cities) of ground rules guiding development
Eight Mandatory Elements of a General Plan
land use
Circulation
housing
conservation
Open space
noise
Safety
Environmental justice
NYC Comprehensive Zoning ordinance, 1916
McAneny and Bassett
Countries first comprehensive zoning resolution
Three categories: residential, commercial, unrestricted
Had five kinds of height districts
Used as a replacement for comprehensive planning
Cumulative Zoning
single family
multi family
commercial
industrial
Euclidean Zoning
From Euclid v Ambler Realty Co. 1926
The division of all of a municipality’s land into use districts and the equal treatment of all of the property owners within each district. (separation of land use)
Zoning
Legislative method of controlling the use of all the land in a municipality by regulating use, lot size, bulk, height, density of population, setbacks, and yards of buildings.
“Zoning Ordinance” is the legal document
in CA, zoning ordinances must generally align with the general plan
Critical Components of Zoning
Use: use of the parcel
Form: the development form
Management: the management of a projects impact
Use (zoning)
Zoning ordinances must serve to protect public health, safety, and welfare
Ordinance must be comprehensive (every piece of land covered) and Fair (each piece of property in the same zone must be treated alike)
Form (zoning)
Zoning envelope specifies setbacks, height limits, and sometimes limits on the percentage of a site that may be covered by buildings, other structures, and paving
FAR
Floor-area ratio
Ratio of building square footage to square footage of land
Ex: 2:1 means for every one square foot of land, two square feet of building are permitted
Management (zoning)
Managing the external effects a building has on its surrounding environment (ex parking)
Changing zoning
Zone change
Variance- permit that enables a landowner to do something on their land (physical cahnge) (must demonstrate a hardship)
Conditional Use Permit - Permit for specific uses that might not normally be allowed if the property owner meets certain conditions
Overlay Zone
An additional zoning district placed over two or more zoning districts
Typically used to add additional standards or regulations along a particular feature
Can permit new uses or restrict uses
Conventional vs. form based zoning
Conventional: uses FAR, setbacks, parking requirements, maximum building heights specified
Form based: street and building types, build-to lines, number of floors
Emerged in 1990s with new urbanism, prioritizes form over use, high quality public spaces, promotes mixed use
Participants in the planning process
local government
rule makers
other government agencies at the state and federal level
private real estate industry
tribal governments
Individuals and citizen groups
Subdivision
Division of a trac or parcel of land into two or more lots for residential, industrial, and/or commercial uses
Reasons for subdivision
Slip uses
Enable different ownership
Enable different financing
Phase development
Increase property value
Subdivision Regulations
Regulations and standards enacted by a community to control the proposed subdivision of land into lots or parcels
Procedures for subdivision renewal and approval
Required improvements (streets, water supply, etc)
dedication of land for parks/open spaces
Silent Spring
Rachel Carson
Launched modern environmental movement
contributed to EPA creation
CEQA
California Environmental Quality Act
State law enacted in 1970 by governor Ronald Reagen following signing of NEPA (National Environmental Protection Act)
Process triggered by discretionary action to identify environmental effects of a project
Legislative vs. Judicial vs. Ministerial acts
Legislative Acts
Discretionary
Creating policy
General plan revisions
zoning ordinances
Approved/adopted by city council
Subjected to initiative and referendum
Quasi-Judicial Acts
Discretionary
Applying discretionary policy to individual projects
Zoning variances
Conditional use permits
Approved/denied by planning commission (appeals decided by city council)
Not subject to initiative and referendum
Ministerial acts
Applying non-discretionary policy to individual projects
Building permit on an approved project
Other permits where all necessary conditions are met
Approved by staff
Not subject to initiative and referendum
CEQA Process
Is the development considered a project?
Is the project exempt?
Conduct an initial study (3-6 months, $30,000-$40,000)
Positive Declaration
Mitigated Negative Declaration (MND) – where developer eliminate all significant environmental effects by changing projects or adopt mitigation measures
Negative Declaration (ND)
If MND or ND, project may proceed
If Positive Declaration, then an Environmental Impact Report (EIR) is required (months ~ years)
Environment Impact Report (EIR)* (months to years)
• Public Review and Comment (30 – 60 days)
• Final CEQA Document
• Decision-Making (months)
• Legal Challenges
CEQA exemptions
Building projects of less than 10,000 sq ft
projects of three homes or fewer in urbanized areas
Projects that will result in “minor alterations of the land’
Urban infill projects up to five acres under certain circumstances
CEQA Shortcomings
Substantive: lack of substantive definitions leads to vagueness about extent of adverse environmental effects
Procedural: extremely long and uncertain process with public comment at each stage
Third parties exploit these shortcomings
California Coastal Commission
Created 1972 by voter initiative
Regulates land use in CA coastal zone
Commissioners appointed by governor and legislature
All land the first 1,000 ft inland from the ocean and as far as 5 miles inland
CA Coastal act 1976
Govern decisions that determine conservation, protection, and use of coastal resources in the coastal zone
Public access, natural resources, long range development
Cities and counties prepare “local coastal plan”
Police Power
Power that permits gov entities to restrict private activities to protect public heakth, welfare, morals
Regulatory Taking
Landowner is deprived reasonable use of their property by gov
Euclid v Ambler
Zoning tested and held up in court
Nollan v California Coastal Commission
Nollans want to build two stories, gov says they have to give up land for public use
