I surfed through several city websites of the constituent cities of Metro Manila to look for any postings about their planning departments. Most of them just listed the department but had little other info. The following had some kind of links to a planning or zoning department:
Only Mandaluyong listed an officer (with an email address) and only Muntilupa listed some sort of process or mission/vision for planning that committed to involving "stockholders." (I suppose they meant stakeholders.)
None talked about comprehensive plans or planning process. None had links to zoning maps.
