-
Landslips### Soil and Building Construction
-
Soil settlement can cause damage to buildings due to the weight of the structure.
-
Topsoil is a critical medium for plants, with features such as:
- Excellent drainage
- Content of humus
- Relative acidity (pH)
- Presence of available nutrients (potassium, phosphorus, nitrogen)
-
Soil drainage is critical, with good drainage referring to the soil's ability to transfer gravity water downward.
Building Layouts
- Level sites are economical in site development but have limitations, such as:
- Surfaces or recreation areas require some pitch for discharging water to surface inlets.
- Sloping sites offer:
- Variety of building types and groupings
- Simpler drainage problems
- Adaptable to various street patterns
- Rolling terrain:
- More difficult to manage but creates a more interesting land development
- Advantages: more interesting land development, economies of first cost in sewer and drainage lines, practice of building parallel to contours reduces costly construction, grading, and filling.
Slope Analysis
- Slope analysis is useful for deciding on land use distribution.
- Slope and land use:
- 0-4%: do not drain well, usable for all kinds of activities
- 4-10%: suitable for movement and informal activity
- >10%: can be actively used only for hill sports or free play
- 17%: approaches the limit that an ordinary loaded vehicle can climb
- 20-25%: normal limit of climb for pedestrians without resorting to stairs
- >50%: may require terracing or cribbing
Hydrology
- Watershed: a geographic area of land bounded by topographic features that captures precipitation, filters, and stores water, and drains water to a shared destination.
- Aquifers: underground "reservoirs" of water that can be contaminated by normal events such as oil spills, fertilizers, waste disposal, etc.
- Water table: the upper boundary of the zone of groundwater, critical for water supply and flood control.
Vegetation
- Relevant in site planning due to its role in:
- Climatic control
- Erosion control
- Architectural and aesthetic uses
- Vegetation helps to:
- Control temperature
- Filter sunlight
- Reduce soil erosion
- Provide shade and moisture retention
- Affect people's moods
Wildlife
- Habitat elements essential for wildlife include:
- Open land wildlife: grain and seed crops, grasses and legumes, hardwood woody plants
- Woodland wildlife: wild herbaceous upland plants, cone-bearing shrubs, hardwood woody plants
- Wetland wildlife: wetland food plants, wild herbaceous plants of moist sites, shallow water development, streams
Microclimatology
- Study of climatic conditions within a limited area.
- Purpose: to discover facts and principles to improve the human condition.
- Factors to consider:
- Altitude and latitude
- Humidity and its effects on bodily comfort
- Wind and air circulation
- Sun and radiation### Microclimatic Principles
- Eliminate extremes of heat, cold, humidity, air movement, and exposure through site selection, plan layout, building orientation, and climate-responsive spaces.
- Provide direct structural protection against solar radiation, precipitation, wind, storm, and cold.
- Respond to seasonal changes by adjusting community site and building plans to the sun's movement.
Ideal Climate for Human Comfort
- Clear air
- Temperature between 50-80°F (10-27°C)
- Humidity between 40-75%
- Air that is neither stagnant nor subject to severe prevailing winds
- Body temperature: 37°C (98.6°F)
Sun Orientation
- Orientation of buildings to sun, wind, and vista is a basic consideration.
- Orientation affects the amount of sunlight admitted to the interior and can be controlled by layout, screening, and overhang.
Plant Materials and Microclimate
- Plant materials (trees and shrubs) serve as aesthetic elements, buffer strips, screens, and dividers.
- Plants affect microclimate by influencing humidity, temperature, and air flow.
- Different types of soil affect temperature and humidity.
Wind Orientation
- Wind orientation affects wind speed and direction.
- Plants can control wind by obstruction, guidance, deflection, and filtration.
- Windbreaks and shelterbelts reduce wind speed by absorbing energy, frictional drag, deflecting wind, and creating turbulence.
Factors Affecting Building Location and Orientation
- Location of buildings on a site affects harmony with topography, livability, drainage, and functional efficiency.
- Orientation of buildings to sun, wind, and vista is a basic consideration.
- Proper siting and orientation reduce noise pollution, drainage problems, and construction costs.
Noise Control
- Noise control can be achieved by evaluating site exposure to roadway noise, adjusting for stop-and-go traffic, and using barriers.
- Effective barriers block line-of-sight exposure to roads and do not have gaps.
- Landscape barriers can provide noise control within the site.
Human Behavior and Environment
- The interaction between human behavior and the environment is a two-way process.
- Behavior is influenced by physical, physiological, and psychological factors.
- Design considers physical, physiological, and psychological factors.
Abraham Maslow's Hierarchy of Human Needs
- Physiological needs (food, water, air, warmth)
- Safety and security needs (psychological and physiological)
- Belonging needs (need for affiliation and membership)
- Esteem needs (need to be held in esteem by oneself and others)
- Cognitive needs (need to learn)
- Aesthetic needs (need for beauty)
- Self-transcendence needs (need for spirituality)
Site Planning and Human Environmental Preference
- Complexity and diversity
- Mystery
- Legibility
- Influence of past experience
- Visual qualities
- Variety of environmental settings
Socio-Economic Factors
- Study of the community and its social and economic structures
- Determine whether there is a need, interest, or objections to the project
- Compatibility with the economy of the community
Historic Factors
- Historical buildings
- Historic landmarks
- Archeology
- Social structure of the community
Pertinent Laws and Utilities
- Determine the existing availability of utilities on site (water supply, etc.)
- Ensure compatibility with the economy of the community and existing laws and regulations.
