(b) The Planning Commission may require that the characteristics of blocks bear close relation to the use of the land.
(c) Irregularly shaped blocks, those intended for cul-de-sacs or loop streets, and those containing interior parks or playgrounds, may be approved by the Planning Commission if properly designed and located and if the maintenance of interior public spaces is covered by an agreement.
