SITE SELECTION CRITERIA
• LOCATION– With consideration of both the regional and local
context– Housing projects shall be within suitable sites for
housing and outside potential hazard prone andprotection areas
• ACCESSIBILITY FROM MAJOR TRANSPORTATIONFACILITIES– Site shall have an existing legal road right of way from
a major thoroughfare

• LOCATION– With consideration of both the regional and local
context– Housing projects shall be within suitable sites for
housing and outside potential hazard prone andprotection areas
• ACCESSIBILITY FROM MAJOR TRANSPORTATIONFACILITIES– Site shall have an existing legal road right of way from
a major thoroughfare
SITE SELECTION CRITERIA
• ZONING AND LAND USE CLASSIFICATION– Classification shall be Residential as defined under
approved CLUP
• TOPOGRAPHY AND SOIL CHARACTERISTICS– Must be relatively flat (or filling requirement for
rolling terrain shall not exceed max cost)– Slopes should not exceed 15% max gradient. For high
density, slope should be below 5%.– Soil characteristics must conform to the suitability
standards for construction by DENR through itsBureau of Mines and Geo-Sciences

SITE SELECTION CRITERIA
• WATER SUPPLY FACILITIES– Source of potable water should be established
whether from local water company, from the ground,or other alternative source
• POWER SUPPLY FACILITIES– Presence of power utility company that will serve the
needs of new community
• DRAINAGE– Natural waterways and outfalls shall be established on
ground8

SITE PLANNING PRINCIPLES
• Compliance to all existing laws, rules andregulations on housing (local or national)
• Adoption of the green infrastructure andpreservation of existing natural assets of the land(e.g., trees, ground cover, vegetation, naturalwaterways)
• Promotion of “walkable communities”

SITE PLANNING PRINCIPLES
• Promotion of appropriate community facilitiesand infrastructure– To serve the socio-economic needs and cultural
activities of the beneficiaries as well as encouragethe implementation of environmentalmanagement programs in the housing sites
– NHA shall provide the minimum requirements forcommunity facilities

HOUSING UNIT DESIGN GUIDELINES
• MINIMUM FLOOR AREA– 22.0 square meters loftable– 22.0 square meters with 11 sq.m loft– 24.0 square meters (for LRBs)
– Models for lots along major roads may be modified toinclude provision of a space for home-based economicactivity, but should not exceed cost parameters
– If new technology or material substitute: must havepassed AITECH (Accreditation of InnovativeTechnologies for Housing)

STANDARDS FOR COMMUNITY FACILITIES
• Provision of community facilities shall bedetermined based on the needs of targetbeneficiaries– Based on existence of public infrastructure within the
5-km radius of the site
• For horizontal development:– 1 covered basketball court/ multi-purpose center– 1 day care center w/ 2 classrooms– 1 MRF– 1 tricycle terminal
