Study Notes

Sieve Mapping Technique

A technique for mapping constraints and opportunities for future settlement growth
Maps can be derived from aerial photos, topographic maps, and other thematic maps
Overlay different maps to identify areas with constraints on the use of land for urban purposes
Blank areas indicate areas with the best opportunities for development.

Site Constraints

Difficult Sites: require more time and money for construction
- Steep slopes require complex foundations, increasing costs
- Poor site drainage and unstable subsurface materials require additional design and construction effort to ensure building integrity
Natural Hazards: ignoring or discounting potential hazards can lead to disasters
- Weather-related hazards are the most common
- Other hazards like earthquakes and hurricanes occur less frequently but with significant impact

Legal and Cultural Constraints

Contextual information is important for ensuring compatibility with existing cultural context
Analyze urban structure, including patterns of mass and space, and the relationships between urban building blocks
Determine symbolic values associated with neighborhood and community spaces

Site Opportunities

Significant Site Amenities: have social, economic, ecological, and aesthetic value
- Specimen trees, scenic views, landmark buildings, etc.
Sense of Place: a community’s character results from factors like:
- Size, massing, architectural design, placement of buildings, streetscape design, open spaces, native landforms, local vegetation and wildlife, etc.
- Older, architecturally significant buildings are important cultural components
Regional Identity: connected with the peculiar characteristics of a location
- Natural processes (what nature has put there)
- Social processes (what people have put there)

Placelessness

Contributes to a lack of sense of place and occurs when:
- New development doesn't respond to local site conditions
- Buildings and sites aren't adapted to their historical and environmental context
- There is a lack of attention to the creation, organization, and connectivity of outdoor spaces
Often, little or no attention is given to space making, leading to placelessness.

Cultural Significance

Our senses of hearing, sight, and smell influence our impressions of the environment
Perceptions of a site are impacted by elements like utility lines, parking lots, and noise levels
Environmental preferences influence people's choices for where they live, shop, work and play.

SWOT Analysis

A tool used to identify:
- Strengths (favorable aspects of the site)
- Weaknesses (unfavorable aspects of the site that can be overcome with design solutions)
- Opportunities (external factors that can enhance the design)
- Threats (external factors that can cause problems for the project)
Understanding these factors is crucial for successful project planning.
