Easement A kind of public open space defined under the Water Code and other laws that must be absolutely free of all forms of physical obstructions that can negatively affect natural light and ventilation within such space or that can impede access to or the full recreational use of such space by the general public. The easement is also for the maintenance of waterways, shore and water bodies. It is the area that may lie between the legally usable portions of public or private property and natural or man-built bodies of water such as seas, rivers, lakes, esteros, canals, waterways, floodways, spillways, and the like. The easement may take the form of natural landforms such as leading to embankments/slope, beach/shores and the like or contain man-built structures such as embankments/slope protection works, linear parks or park strips, promenades, wooden boardwalks and the like.

ROAD RIGHT-OF-WAY (RROW) or ACCESS STREET or STREET Public space for continuous flow of pedestrian and vehicular traffic that must be free from prohibited physical obstructions. Area lying between two or more properties and its width measured from opposite property lines The RROW consists of three (3) different physical levels as follows: RROW ABOVE GRADE – refers to the portion of the RROW reckoned from the finished surface of the roadway/carriageway and/or the sidewalk/arcade all the way up to the air. If this level of the RROW is utilized For whatever purpose, the AIR RIGHTS or the right to develop, benefit and profit from the use of RROW above grade is given up by the government/general public and should therefore be compensated, i.e., leased and paid for by the proponent/end-user/beneficiary of the proposed building/structure. The minimum clear height for the utilization of the air rights above RROW shall be 4.27m from the finished crown elevation of the roadway/carriageway. RROW AT GRADE – refers to the portion of the RROW reckoned from the natural grade line up to the unfinished surface of the roadway/carriageway and/or the sidewalk/arcade. This portion of the RROW is generally utilized for the movement of the general public (motorists and pedestrians). If this level of the RROW is utilized for whatever purpose, the right to develop, benefit and profit government/general public and should therefore be compensated, i.e., leased and paid for by the development proponent/ end-user/beneficiary.


JMPDL,uap

AIR RIGHTS – the right to physically develop and subsequently benefit or profit from the use of the air space above the RROW. Private property owners cannot lay claim to air rights within the RROW because it’s part of the public domain.

Whenever the slope of the street is 1/10, the sidewalk shall be maintained level for every 20.00 to 40.00m of the run. Sidewalks of different levels shall be joined by means of a ramp having any convenient slope not exceeding 1/6. Driveways Across Sidewalks To maximize the use of the sidewalk area, the surface of the sidewalk and the driveway shall as much as possible, be at the same plane. The entry ramp of the driveway connecting the roadway surface to the sidewalk surface shall have a slope ranging from 1/3 to 1/4. Whenever the height of the curb is more than 200mm, driveways may be constructed across the entire width of the sidewalk, provided that the driveway shall be joined to the sidewalk by means of a ramp of rough finish have a slope not more than 1/8. The driveway and the ramp shall be made o the same materials as that of the sidewalk.
