Section 7Sec./Art. 7

Design Standards and Planning Considerations. The following design standards and planning considerations shall be observed by all projects covered by these Rules.

A. Water Supply

1. Underdeveloped Area

Minimum requirement shall be provision of communal wells.

Water supply must be potable and adequate at least 43 liters per capita per day. Supply source shall be identified and developed by the project developer/owner.

Whenever a body of water shall be utilized for community waters supply, permits from the National Water Resource Council (NMRC) shall be obtained. Standards set by the Regional Water Resource Council (RWRC) on water source development shall be complied with. Each well shall be allocated approximately four (4) square meters area which shall form part of the area for community facilities (as defined in Rule II) and shall not encroach on any saleably lot or right of way.

2. Developed Area

Whenever a public water supply system exists, connection to it by the subdivision is mandatory. Each lot and/or living unit shall be served with water connection (regardless of the type of distribution system). Water supply provided by the local water district shall be complemented/supplemented by other sources, when necessary, such as communal well which may be located strategically for ease and convenience in fetching water by residents and at the same time not closer than 300 meters from each other.

If public water supply system is not available, the developer shall provide for an independent water supply system within the subdivision project. Minimum quantity requirement shall be 75 liters per capita per day.

Likewise, required permits from the NWRC shall be obtained and standards of the Local Water Utilities Administration shall be complied with.

If ground reservoir is to be put up, and area shall be allocated for this purpose (part of allocation for community facilities). The size shall depend on volume of water intended to be stored. Provide for protection from pollution namely, buffer of at least 25 meters from sources of pollution/contamination.

For elevated reservoir, structural design shall comply with accepted structural standards.

B. Circulation System

1. Circulation system shall be the same in both Underdeveloped Area and a Developed Area projects except for type of pavement which is adopted on regional or locational peculiarities of the project site.

Note: Paving material for roads adopted from Models A and B (PD 957) shall have the same paving materials as cited herein, i.e., asphalt.

2. Planning Considerations or Circulation Layout

a) Observance of the hierarchy of roads within the subdivision.

b) Conformance to natural topography.

c) Consideration for access and safety e.g. adequate radius, minimum number of roads at intersections, moderate slope/grade, adequate sight distance, no blind corners, etc.

d) Optimization as to number of lots to lessen area for roads, at the same time enhance community interaction.

e) There shall be no duplications of street names and such names shall not bear any similarity to existing street names in adjacent subdivision, except when they are in continuation of existing ones. Street names shall be recognizable and readable.

The developer shall bear the cost of purchase and installation of street names/signs coincident with the construction of streets and utilities.

f) Sidewalks shall not be required when drainage system is through open canals; when drainage canals are covered or underground, the space above the canals shall be utilized as sidewalk.

C. Drainage System

Drainage system shall be required in all projects.

An open canal on each side of the circulation network shall be provided. Said canal shall have appropriate slope to effect good drainage. Moreover, the sides of the open canal shall be lined with grass or stones to prevent erosion. See illustration below.In case of non-existence of drainage system in the locality, catchment area for drainage discharges shall be provided for and developed by the developer/owner in consultation with local authorities or private entities concerned, to prevent flooding of adjacent property. Moreover, said catchment are shall be made safe and maintained and shall form part of the park/playground requirement.

D. Sewage Disposal System

The minimum requirement for sewage disposal shall be the use of septic tank.

For single detached units and multi-unit buildings, communal septic tanks maybe allowed.

Drainfield area of affluent shall be 25.00 meters minimum distance from any sources of water (well, spring, etc.).

E. Electrical Power Supply

1. Underdeveloped Area

Electrical power supply is optional. However, the developer shall allocate sufficient land area for easements for power supply facilities based on existing laws and regulations.

2. Developed Area

When power is available within the locality of the project site, its connection to the subdivision is required. Actual connection, however, may depend on the minimum number of users as required by the power supplier. Installation particles, materials and fixtures used, shall be in accordance with the provisions of the existing rules and regulations of the Electrical Code of the local power utility company.

F. Lot sizes

1. Minimum lot area requirement shall be as follows:

a) Detached dwelling unit 72.00 sq. meters

b) Semi-detached dwelling unit

a. corner lot 54.00 sq. meters

b. row house d.u. 36.00 sq. meters

2. Lot Planning consideration (applicable to both Underdeveloped Area and Developed Area Projects).

a) A lot shall either be served by a road, motor court, an alley or a pathway.

b) Deep lots and irregularly shaped lots shall be avoided.

c) Lot elevation may be at grade, lower or higher than the elevation of the street but should not be so excessive as to effect good utility connection/run.

d) Lot lines shall be perpendicular or radial to street lines in appropriate cases.

e) Lot shall be protected against non- conforming uses and/or other risk through provision of adequate buffer strip, protective walls, and roads or other similar devices. On the other hand, lot shall be laid out that they front desirable views, such as parks, lagoon, etc.

f) Lot shall be so laid out that water courses/drainage ways do not bisect the lots.

g) Minimum lot frontages:

Single detached 8.00 meters

Single attached 6.00 meters

Row house/irregular lot 3.50 meters

G. Block Length

Maximum block length is 250 meters. Block length exceeding 250 meters, but not beyond 400 meters, shall be provided by an alley at midlength.

H. Easements

Provisions for easements in both Under-developed Area and Developed Area projects shall be integrated with utility network/part of right of way.

I. Other Facilities

1. Garbage Disposal System

Garbage disposal shall be undertaken by the local government or in the absence thereof by individual lot owners, but shall always observe sanitary practices and methods.

2. Firefighting

The Homeowners Association shall form fire brigade in collaboration with the barangay fire brigade. Water for fire fighting shall be part of the water supply requirement and shall comply with the requirements of the local/district fire unit of the Integrated National Police.
