Study Notes
Site Development
- Involves the preparation of land for building or other uses.
- Transforms a raw parcel of land to meet various needs, like housing, commercial, industrial, or recreational.
- Site selection involves identifying appropriate locations for a specific development.
Site Suitability
- Considers the site's technical qualities and its ability to meet development requirements.
- Factors considered include:
- Topography
- Slope
- Soil characteristics
- Facilities:
- Water supply
- Power supply
- Drainage outfall
Site Development Plans: Typical Contents
- Cover Sheet: Project title, vicinity and location maps, northings, scale, table of contents.
- Site Development Plan: Site plan, land use percentages, total number of lots, northings, scale, contour lines, road numbers, block and lot numbers.
- Topographic Map: Topographic map, technical description, TCT number, benchmark, northings, scale.
- Road Layout: Road layout, road numbers and stationing, road right-of-way, contour lines, details, northings, scale.
- Road Profile and Lot Grading Plans: Road profiles, road sections, site grading, original ground elevation, designed grade elevation, details of slope protection, northings, scale.
- Drainage Layout: Drainage layout, canal/pipe sizes, flow direction, details, contour lines, northings, scale.
- Water System Layout: Water system layout, pipe sizes, appurtenances, details, northings, scale.
Signatories for Land Development Plan
- Relocation and Boundary Survey, Topographic and Structural Map, Survey: Registered Licensed Geodetic Engineer.
- Site Development Plan, Subdivision Plan, Road Layout, Road Profile and Lot Grading Plans: Registered Licensed Civil Engineer.
- Waterline Layout, Drainage and Sewer Layout: Registered Licensed Sanitary Engineer.
- Sewage Treatment Plant Design: Registered Licensed Mechanical Engineer and/or Registered Licensed Sanitary Engineer.
- Street Lighting Layout, Power Distribution Layout: Professional Electrical Engineer.
- Fire Protection System: Professional Mechanical Engineer.
Aspects of Land Development: Planning Considerations
- Hierarchy of Roads: Observe the hierarchy of roads within the subdivision. Road elevations should conform to the natural topography.
- Road Intersections: Minimize road intersections and blind corners. Streets should intersect at right angles.
- Offsets: Offsets should be far enough to prevent vehicles from cutting diagonally across the road.
- Corner Cuts: Cut a corner portion of the block to allow smooth vehicle changes and better visibility. The minimum corner cut is 3.00 meters for chopped.
Road Right of Way (RROW)
- Typical RROWs:
- 6.5 meters
- 8.0 meters
- 12.0 meters
- 14.0 meters
Easement
- Article 51 of Presidential Decree No. 1067 (The Water Code) states that the banks of rivers and streams, shores of seas and lakes have public use easements with these zones:
- 3 meters in urban areas
- 20 meters in agricultural areas
- 40 meters in forest areas.
Road Work Details
- Curbs and Gutters: Concrete curb and gutters are built at the road's perimeter to reinforce the road surface. They are at least 0.275 meters high to allow water to flow at depth.
- Construction Joints: Used to strengthen the slab. Properly designed and spaced joints minimize cracking outside the joint area. Sawed into hardened concrete with a depth of approximately 1/4 of the pavement slab thickness.
Accessibility
- Dropped Curbs: Provided at pedestrian crossings and the end of footpaths. Ramped towards adjoining curbs with a gradient not more than 1:12. Sloped towards the road with a maximum cross gradient of 1:20 to prevent water accumulation.
- Walkways/Sidewalks: Kept level and provided with slip-resistant materials. Minimum width of 1.20 meters.
- Parking for Persons with Disabilities: Allocated at a ratio of 1 slot for every 8 parking lots.
Planting Strips and Greening
- Referenced by BP 220 and PD 957.
Drainage System
- Should be preceded by accurate field surveys.
- Consider meteorological conditions, rainfall, atmospheric temperature, and dry weather days to minimize the effects of hazardous occurrences.
- Wastewater Treatment: Sewage should be treated before being discharged to the ground or waterways.
- Storm Drainage: Storm drainage and sewerage systems are separately designed for better treatment of sewage and enhanced Sewage Treatment Plant (STP) performance.
- Drainage Outfall: Directed to discharge in the direction of flow in the main waterways.
Water Distribution System
- Service Connections
- Fire Hydrant System
- Pipe Trench
- Pipe Thrust Block
Electrical System
- Electrical Poles
- Solar Street Lights
Other Considerations
- Perimeter Fence
- Slope Protection
