All subdivisions should result in the creation of lots which are developable and capable of being built upon. No subdivision should create lots which are impractical for improvement due to steepness of terrain, location of watercourses, problems of sewerage or driveway grades, or natural physical conditions.

In the coastal zone, no lots intended for urban development shall be created so as to consist totally of land or water designated as environmentally sensitive habitat areas in the certified local coastal program.
