Classic Neighborhood Theory
(old way) |
|
Definition
separate different uses
-shopping on outskirts
-industrial separate
|
|
|
Term
|
Definition
Mixing uses (not so much zoning)
-social centers in the middle of neighborhoods
-shopping areas within living areas (like shops of Legacy and college park) |

1-think schematically at scale then add details
2-ID site features and building envelope
(set backs, easements, trees, mineral rights, etc)
3- locate points of access
4-place building comfortably to site
5-layout and circulation & parking
6-final details and presentation (trees, benches)
7-keep it simple - usu. the best way |

|
Definition
1- ZONING:land use maps (how to look for specific sites)colors tell different uses
2-SUBDIVISION - layout, circulation, drainage - environmental effect and utilities
3-SITE PLAN -take comprehensive plan concept and apply it to a specific site
4-BUILDING PLAN
5-INSPECTION |

Definition
-Survey for property boundaries
-Local codes
-Land uses
-existing site improvments
-micro-climates (sun, wind, rain)
-topography
-soils
-surface drainage and ground water
-vegetation and wildlife
-historic/cultural importance

Definition
-Dashed lines = existing, solid = new proposed
-even spacing indicates uniform slope
-closer spacin indicates steeper slope
-contour lines point up valleys or down ridges
-contour lines never cross
-ridgetops and valleys are always shown in pairs
-HP = highpoint, LP= low point
are indicated by spot elevation
-water flows perpendicular to contour lines |

SLOPE can be expressed in three ways: |
|
Definition
Percent ( %, most often)
Ratio (x:x)
Degrees (x') |
|
|
Term
|
Definition
Slope (also gradient or grade) =
Difference in elevation/ length

Q (peak of water runoff) = CIA
where:
C=coefficent of runoff (% of rainfall that runs off a surface)
I=Intensity of rainfall
A=area of watershed acres |

Site Grading
General Principles
(making adjustments to the topo) |
|
Definition
-disturb site as little as possible
-maintain natural drainage flow
-avoid sensitive areas
-maintain natural repose of soil (do a soil study)
-work from high to low
-make it look nice lastly |

What is the strongest form generator - and most costly improvement on every site development? |
|
Definition
Parking and circulation
- Parking has different ratio requirements per land use |
|
|
Term
General Design Rules for circulation and Parking |
|
Definition
-mutual access drives with adjacent sites to avoid offset alignments
-no prkng within main circulation aisle (fire land and loading and drop off areas)
-separate service routes & drive thrus from main circulation and parking
-circulation lanes are perpendicular to large destinations (entry) within larger lots but parallel to smaller convenience destinations in small lots (7/11) |
|
|
Term
|
Definition
- avoid deadend parking and service routes
-don't mix parallel and 90' spaces
-prefer using both sides of an aisle
-90 degree is preferred for efficiency

Definition
r+t=21" (rise+tread)
-should occur in pairs
-more than 9 should be separated with a landing
-6%preferred slope for ramps
10% is ok for short distances |
