Parks

Institutions

Mixed Use

Transport / Parking

Vacant Lots

- To promote and protect the public health, safety and general welfare - Established height and setback controls- Separated residential areas from some non-residential uses (industrial and manufacturing)

How does zoning work?

Each zoning district regulates:

• Types of uses allowed

• Density (floor area ratio; FAR)

• Overall density

• Density of individual

uses

• Building Form

• Number of dwelling units

• Amount of open space

• Required parking (if any)

• Lot coverage

• Distance from buildings and lot

lines

Group Type of Use

1 & 2 Residential

3 & 4 Community Facilities

5 - 9 Commercial / Local retail & Services

10 - 11 Regional Shopping Centers/Amusement

12 - 15 Waterfront / Recreation

16 General Services / Heavy Automotive

17 & 18 Manufacturing

Uses are grouped based on common functional or nuisance

characteristics. Zoning text identifies which use groups are

permitted in each zoning district.

• Every zoning district has a floor area ratio (FAR).

• The FAR reflects the ratio of building floor area to lot

area.

• Multiplying the FAR by the lot size will give you the maximum

permitted floor area (size) or square footage of a building.

Urban Growth Boundary

• The boundary is combined with a number of policies that promote rather than inhibit increases in density.

• In other words, the growth boundary is an integral part of urban planning, the set of policies that determine the spatial arrangement of activities in metropolitan

• refers to the manner of utilization of land, including its allocation, development and management.

• To direct, harmonize and influence discussions and activities of the private and public sectors relative to the use and management of lands

• To reconcile land use conflicts and proposals between and among individuals, private and government entities relative to the present and future need for the land

• To promote desirable patterns of land uses to prevent wasteful development and minimize the cost of public infrastructure and utilities and other social services

• to preserve areas of ecological, aesthetic, historical and cultural significance

• Philippines remains as one of the hottest biodiversity “hotspots” in terms of high vulnerability and high irreplaceability (Ong 2007)

• National Integrated Protected Area System Act in 1998

Environmental Zoning for Biodiversity Conservation

ENVIRONMENTAL ZONING

• Is the first of the environmental protective planning which aims to balance relationships between environment and the increase of the standard quality of life

Principles of EZ:

• The land-use and resource must be rational in all zones, subzones and units

• Protection and rehabitation of the ecosystem

• To take unforeseen circumstances into consideration if possible.
