(1) "Group Development" means accommodation for residential, commercial or institutional building in two or more blocks of buildings in a particular site irrespective of whether these structures are interconnected or not. Any inter link between the structures in terms of connecting corridors shall not be construed as making any two structures into one block. However, if these blocks are connected solidly at least for one-third the width of any one block on the connecting side, then, such block shall be construed as a single block.
(2) (a) The minimum width of the public road on which the site abuts or gains access shall be 9 metres.
Explanation.-- The qualifying road width for permitting Group development shall be available for a reasonable stretch say about 250 metres along the length of the road abutting the site and the stretch from a junction can be straight or a curve or zigzag or combination of the above. Any deviation on road width shall be referred to Empowered Committee whose decision shall be final.
To cite examples:--
(i) If the road over its general length is of 9 metres width, but because of some kinks in front of the site, the two ends show a minor variations, reasonable allowance for such variation may be given so that it averages out to 9 metres.
(ii) If the general road is of width less than 9 metres width, but only widens opposite to or nearer to the site is more than 9 metres, is not acceptable.
(iii) If the general road is of 9 metres width upto a considerable length on one side, but discontinues and narrows into a road of smaller width on the other side of the site in question and the plot owner is willing to leave enough space for continuity of 9 metres road in front of his site, this will have to be checked and decided on case-by-case and such cases may be referred to Empowered Committee.
