bro -- under the local government code in book 1, title 1, chapter 2, it provides:
"SECTION 19. Eminent Domain. − A local government unit may, through its chief executive and acting pursuant to an ordinance, exercise the power of eminent domain for public use, or purpose, or welfare for the benefit of the poor and the landless, upon payment of just compensation, pursuant to the provisions of the Constitution and pertinent laws: Provided, however, That the power of eminent domain may not be exercised unless a valid and definite offer has been previously made to the owner, and such offer was not accepted: Provided, further, That the local government unit may immediately take possession of the property upon the filing of the expropriation proceedings and upon making a deposit with the proper court of at least fifteen percent (15%) of the fair market value of the property based on the current tax declaration of the property to be expropriated: Provided, finally, That, the amount to be paid for the expropriated property shall be determined by the proper court, based on the fair market value at the time of the taking of the property."
thus, taking can be done for the following reasons: a) for public use; b) public purpose; c) public welfare for the benefit of the poor and landless
the 1987 philippine constitution also provides in article III (the bill of rights):
"Section 9. Private property shall not be taken for public use without just compensation"
the constitutional basis for taking is simply and generally
"public use"
the above gives you the legal basis for the act of the local government of paranaque
as to what is public use, we have jurisprudence on that matter
