Title: PHYSICAL DEVELOPMENT
1PHYSICAL DEVELOPMENT
- Part 1
- Basic Subdivision/Allotment
2Definitions
3SUBDIVISION
- The division of land into two or more tracts,
blocks, parcels, or lots for the purpose of sale,
resale, development, or other form of valuable
interest, including the re-subdivision of land
4PLAT
- A survey map of development including all the
necessary bearing and monument necessary to
accurately locate any point within the surveyed
area
5Sketch Plan
- A to scale hand drawing of the land development
showing the basic terrain, lot, and street layout
6Plat - Preliminary
- A to scale mechanical drawing with precise
topography and prescribed intervals showing the
calculated location of all lots, streets,
drainage patterns, facilities, and proposed
dedications
7Plat - Final
- The survey reproduction of the approved
preliminary plat with all bearing, monuments,
curves and notations, together with all
dedications, easement and approvals
8A Reservation
- A notation on the final plat that a specific
portion of the land will be set aside for future
government purchase - A notation on a final plat that a permanent
easement has been retained for the use and
enjoyment of those entitled by deed to use this
land for a specific purpose
9Dedication
- A gift, together with the land owners offer to
transmit, of land to be used for a public purpose - Roads and streets
- Utility lines
- Parks
- Trails
10Exaction
- A demand by the government that the developer
either dedicate certain property or monies for
public use to hold the project harmless from
public obligation. Exactions must be roughly
proportionate to the impact of development
11Impact Fee
- A form of Exaction
- Fees contributed to offset the proportional cost
of off-site development impacts
12Subdivision Bonus
- An offer to extend development benefits beyond
those normally offered in exchange for
enhancements - Affordable housing
- Cluster housing
- Open space retention

15History
- Platting, or allotment, is an ancient science
probably originating with the first serious
attempts at elementary trigonometry - In the U.S., plats of towns and additions to town
first appeared in 1660 - Law of the Indies
16Frederica, Georgia
17Lexington, KY Deed of Plat
- "The following is the plan of the town of
Lexington as laid out by Jesse Henley, Esq.,
Nehemiah Hunt and William McFarland, within the
County of Jefferson, Indiana Territory, being a
part of the Southeast Quarter of Section 33, and
part of the Southwest Quarter of Section 34,
Township S North, Range S East. Each street in
the town of Lexington to be 60 feet in breadth,
each alley to be 10 feet in breadth, to remain as
open and common highways forever and Lots No.
27, 28, 33, 34, 39, 40, 45 and 46 to be and
remain for the purpose of erecting any public
building or sinking a well for the public
benefit provided also that no part shall ever be
appropriated as a burying ground, nor subject to
being disposed of by any person, but to remain
forever for the express purposes granted. Each
lot 90 feet in breadth and 180 feet in depth.
Given under our hands the 1st day of June, 1813.
Jesse Henley, William McFarland, Nehemiah Hunt."

19Modern History
- Process moves to regulatory stage at the same
time zoning is given constitutional approval
1926 - Developed as an approval process during the
1930s - In 1940s the relationship to the official map
20Relation to Mapped Streets
21Purpose
- Provide a coordinated, unified system of town
development - Provide a universal set of development standards
- Public and consumer protection
- Official registration of land
- Regulatory and review process for quality control
- Land form design and intelligent layout
22The Players in the Process
- The landowners and the ripening process
- The developers
- Surveyors and engineer
- The planners and the government
- The public holding them harmless
23The Process the Conference
- Information Exchange
- Basic market plan
- Basic site selection criteria
- The pre-conditional checklist
- Resources and habitat
- Utilities, roads, and facilities
- Preliminary evidence of feasibility
24Diversion Short Plats/Splits
- Many minor developments are fast-tracked
- Lot splits are usually allowed if they result in
two conforming lots an create no new street or
easements - Minor subdivisions are usually allowed (5 or less
lots) with no new streets - Consent agenda
25The Sketch Planning Process
- The sketch plan reviews, at a conceptual level,
the physical design characteristics of the
proposal based on the standards set forth in the
subdivision regulations
26Basic Sketch Process
27Sketch Process - Topography
28Sketch Process - Drainage
29Sketch Process - Cover
30And, Voila! The Final Sketch
31Preliminary Plat
- A scaled non surveyed, mechanical map of the
proposed layout (including context) - Precise Topo
- Lots
- Prominent features
- Streets
- Facilities
32Preliminary Plat
33Prelim Plat Procedure
- Staff reviews for concept changes
- Staff reviews for compliance check
- Developer makes changes or the argument begins
- Developer resubmits and the plat is precise
checked
34WARNING
- The following picture was inserted for some
levity it is a bit off-color. However, it does
show the problems of changeable signs near
schools. If you are easily offended, skip over
it! - Keller
35Short Reality Check
36What About Developer Rights?
- Zoning commands strong property rights
- Subdivision is SALES! They are selling lots to
the public. They have about the same level of
protection as a used car salesperson
37Returning to the Process
- The preliminary plat is routed to the review
teams - Engineering
- Parks and Rec.
- Utilities
- Fire Protection
- Others
- Schedule for agenda review
38Planning Commission
- Developer Presentation
- Staff Report
- Public Comment
- Engineering Report
- Planning Commission changes and modifications
- Developer rebuttal
39Final Plat
- If the developer accepts all changes and
recommendations, the final survey process begins - The final plat is submitted to staff for a
compliance check - The plat is reviewed by engineering and mapping
for technical errors or omissions
40Approval
- The planning commission must accept the final
plat if - All changes and modifications from the
preliminary plat are completed - The staff report indicates that there are no
substantial changes - No exceptional or extra-ordinary information has
come to light since the preliminary plat was
reviewed
41Implementing Exactions
- The developer is required to install and certify
correct operation of all infrastructure required
to complete the project before building permits
will be issued - Developer often required to post a method of
assurance that facilities are installed to public
specifications
42Funding Special Obligations

credit - The role of the engineer cost estimation and
inspection - Bond Counsel

49Affordable Income Guideline
50Affordability
- At the end of 1999, the state's estimate of
median household income was 64,795. My analysis
of first-time buyers assumed they had incomes at
70 percent of median - 45,356 - put 10 percent
down, and bought houses worth 85 percent of the
median price.
