SITE

• Any area which has played a significant role in the history of

our country.

• Such significance may be:

• Historical

• Cultural

• Archaeological

• Sociological

• Scientific

2

• SITE - A space or ground occupied or to be occupied by a building or a concentration of building developments or human activities that fall under the same land use category;

• Through site planning, a site is made suitable for building purposes, human activities, or life sustaining processes;

• A site for human activities (production and consumption) may be divided into lots, street pattern, and provided with such facilities as water, sewer, power, drainage, etc.

• Every site is a unique interconnected web of things and activities that imposes limitations and offers possibilities.

• A SITE (“Project Area” or “Planning Area”) varies in size, location and characteristics.

SITE PLANNING

The art and science of arranging the uses of

portions of land. These uses are designated in

detail by selecting and analyzing sites, forming

land use plans, organizing vehicular and

pedestrian circulation, developing visual form

and material concepts, readjusting the existing

landforms by design grading, providing proper

drainage, and developing the construction

details necessary to carry out the projects

SITE PLANNING

Physical Planning is the art and science of

ordering the use of land and siting of buildings

and communication routes to secure the

maximum practicable degree of economy, social

amenities, convenience and aesthetics. It

involves the following components: physical,

social, and economic/administrative

There are two methods of establishing a site:

1. Site Selection Process

• The process selects from a list of potential sites one that suits

best the given use and requirements of the project.

2. Development Suitability Process

• This process selects the best possible use and development

suited for a given site.

Soil Types and Drainage

“Good drainage” refers to the soil‟s ability to transfer gravity water downward, and that the soil is not conducive to prolonged periods of saturation.

“Poor Drainage” is when the soil is frequently or permanently saturated and may have water standing on it. This maybe caused by local accumulation of surface water, or rise in the level of groundwater within the soil because because the soil particles are too small to transmit infiltration

‣ Infiltration capacity: rate at which water penetrates the soil surface (cm/hr or inches/hr) ‣ Permeability: rate at which water within the soil moves through a given volume of material (cm/hr or inches/hr) ‣ Percolation: rate at which water is absorbed back by soil ‣ Porosity: capacity of soil or rock to hold water; ratio of the volume of void spaces in a rock or sediment to the total volume of the rock or sediment.

12

Hydrology

Hydrology: the science that studies the waters of the earth, their occurrence, circulation and distribution, their chemical and physical properties, and their reaction to the living environment

•Intense rainfalls promote highest rate of soil erosion

13 Short Course on Environmental Planning

DCERP & HUMEIN Phils. Inc.

•Aquifer: permeable geological stratum/formation that can both store and transmit groundwater in significant quantities

•Watershed: geographic area of land bounded by topographic features and height of land that captures precipitation, filters & stores waters to a shared destination; this is important in water quality and stormwater management

14

Hydrology

Climate

Four types: cold, temperate, hot arid & hot humid.

Topography, surface materials, plant cover, location of structures, and presence/absence of water have striking impact on the microclimate

Solar orientation

Best-facing slopes

Wind flows

15

Climate

Albedo: characteristic of a surface; fraction of total radiant energy of a given wavelength incident on a surface reflected back by that surface

Passive Cooling: technology of cooling spaces through proper siting of structure and use of energy-efficient materials, with the overall objective of energy conservation

Site Selection & Analysis

‣ Site Selection Process: selects a site that suits best the given use and

requirements of the project; based on an established criteria

‣ Development Suitability Process: selects the best use and

development suited for a given site; site analysis using various tools

and procedures

‣ Site analysis involves studying the site in terms of various factors,

namely: (1) natural; (2) cultural; (3) aesthetic

‣ In site analysis, it is important to gather existing data about the site

and its immediate environs. This involves site reconnaissance, data-

gathering/research, and even surveys.

• The development of the program is the bridging step between the analysis and synthesis or design phases.

• Kevin Lynch defines the program as composed of the four “P’s”:

• “Population” refers to the actual user who may or may not be the client per se.

• “Packaging” involves the type and quantities of elements that will be provided in the design.

• “Performance” standards set the quality of elements expected, whether in terms of materials or function.

• “Patterns” refer to general physical relationships that should be achieved.

2. Program Development

32

Short Course on Environmental Planning

DCERP & HUMEIN Phils. Inc.

• As Simonds explains, in developing the program the designer responds to the client’s initial statement of intent, modified on the basis of what he/she has learned at the end of the analysis phase.

• While the analysis is based upon a basic program concept, the potential of the site for development influences the planner’s ultimate program recommendations. The program should include: a. A statement of goals that the project should achieve. b. A list of project objectives by which these goals will be accomplished. c. A list of project elements that will be included and a description or analysis of their interrelationships.

SITE PLANNING

Site planning, then, is the organization of the external physical environment to accommodate human behavior. It deals with the qualities and locations of structures, land, activities, and living things. It creates a pattern of those elements in space and time, which will be subject to continuous future management and change. The technical output – the grading plans, utility layouts, survey locations, planting plans, sketches, diagrams, and specifications, are simply a conventional way of specifying this complex organization.

• Site Planning occurs after Strategic Planning has taken place

and after the land use has been decided in relation to social,

economic, and environmental needs.

• Site planning is an integral part of land use planning that

involves the arrangement of structures, natural or man-

made, on the land and shaping the spaces between.

• “Site Planning” involves planning for a smaller urban area

already defined for commercial, residential, industrial,

recreational, or mixed use development.

SITE PLANNING

43 Short Course on Environmental Planning

DCERP & HUMEIN Phils. Inc.

• Site planning determines the detailed layout of an area so that

it functions effectively in relation to a given range of land uses

on the site and others around it.

• Site planning is working out the detail of:

1) what should happen on a given area of land;

2) how it should happen;

3) what it will cost to implement and manage proposed

developments on the area of land.

• The purpose of PUD is to provide property owners the

flexibility to plan for the development of their land in a manner

that clusters new homes onto small lots while preserving large

areas for agricultural use or as undeveloped open space.

• PUD provisions can specify the percentage of land that

should be set aside (not subdivided into building lots or

developed).

• The minimum set aside is typically 40% or more of the original

parcel.

• Municipalities can be creative and use density bonuses as

a “carrot” to promote a range of community goals and

increase use of PUD provisions.

• A density bonus of 1.0% for every additional 0.5% of the

original parcel set aside as undevelopable above the

minimum 40% set aside required

PUD and Density Bonuses

DCERP & HUMEIN Phils. Inc.

• To encourage clustering and conserving large blocks of

undeveloped lands, density bonuses are linked to the

percentage of the original parcel being set aside. The more

land the subdivider is willing to conserve, the greater the

bonus received.

• The density bonus results in more lots or units than would

otherwise be allowed based on zoning district regulations.
