site inventory and analysis . . .


Fall 2005 2

phase one: site inventory . . .

linkages between site and surrounding landscape

three types1. physical

2. biological

3. cultural


Fall 2005 3

for each type of site inventory . . .

collect the essential data

map the essential data


Fall 2005 4

do a site reconnaissanceidentify potentially significant site assets

identify potentially significant site liabilities

develop a base map

attributes of the site . . .


Fall 2005 5

base map . . .is a template for attribute mapping and analysisis a template for subsequent planning and designshould include

topographic characteristicsclimate indicationsproject boundaries

(adjunct aerial photographs are helpful)


Fall 2005 6

base map . . .

must be embedded in its contextcultural context of surroundings

circulation of surroundings

views into surroundings

“urban fabric” shown so that your site design will be related


Fall 2005 7

eight types of topographic site data . . .

5. topography

6. vegetation

7. soils/geology

8. hydrology

1. legal

2. utilities

3. structures

4. circulation


Fall 2005 8

types of topographic site data (cont.) . . .

1. legalproperty lines and distances

easements and building setback lines

site area


Fall 2005 9

feelingsensation

intuition

2. utilitiestype (sanitary sewer, electric, gas, telephone)

manholes, hydrants, and other fixtures



Fall 2005 10


3. structuresbuildings

height

width

articulation (fenestration)

visual quality

sense of place

historical significance


Fall 2005 11


4. circulationexisting streets and rights-of-way

existing curbs and gutters

existing parking areasparking requirements


Fall 2005 12


5. topographyelevational change = contour lines on mapsspot elevations for high and low points

USGS maps available –

topographic survey gives info on three important and fundamental landform components = elevation (spatial variation), slope (gradient), and aspect

(orientation)


Fall 2005 13

site elevationsaffects drainage patterns

affects visibility

variation of elevationdetermines size and spatial configuration of local viewsheds

on site and into surrounding landscape

5. topography (cont.)


Fall 2005 14

6. vegetationwooded areas

isolated trees species and diameter at about five feet high



Fall 2005 15

7. soils/geologyborehole samples may be taken for analysis in an undeveloped site



Fall 2005 16

8. hydrologysurface water

wetlands

hundred-year floodways and flood fringe



Fall 2005 17

the climate . . .varies annually, seasonally, dailydetermines the USDA Plant Hardiness Zone

eleven zoneshttp://www.usna.usda.gov/Hardzone/ushzmap.html?

Fall 2005 18

temperaturemaximum, minimum, day-to-night variation

humidityhigh, low, averages

windmaximum, average velocity, direction

rainfallmonthly total, maximum for any one day

snowfallmonthly total, maximum for any one day

solar radiationmonthly average

climate data (cont.) . . .


Fall 2005 19

in urban settings, particularly . . .

shade diagrams are important10:00 a.m.noon2:00 p.m.4:00 p.m.

the above shown at the time ofthe summer solstice (around June 21)the winter solstice (around December 22)vernal or autumnal equinox (near March 21 or September 22)


Fall 2005 20

noise factor must be consideredbuffering needed?

materials?

vegetation?

location?

also in urban settings . . .


Fall 2005 21

phase two: site analysis . . .

identify the criteria for each anticipated land use

identify site locations that meet the identified criteria

map these onto the base map


Fall 2005 22

another way to phrase it . . .

what are the site’s constraints, based on the program requirements?

what are the site’s opportunities, based on the program requirements?

map these onto the base map


Fall 2005 23

additional design factor to consider . . .


Fall 2005 24

important for two aspects of the built environment

heating and cooling of buildings

comfort of people using outdoor spaces

a site’s microclimate . . .


Fall 2005 25

modifying the microclimate . . .vegetation

shade trees intercept solar radiationleaves of plants cool through evapotranspirationcertain chemical pollutants removed from the airoxygen added to the atmosphere

color of hardscapesdark = absorbs heat and re-radiates it into the atmosphere

vertical elements (structures/trees)shadow patterns as the sun moves through the site in summer and winter

cools in summer

open spaceslets solar heat into the site in the winter
