(5) Parks and playgrounds. Details for individual land use sub-division is given under bye-law nos. 33.2 to 33.5.

(1) Service Roads,
(2) Collector Roads,
(3) Other roads either proposed in the Regional plan Master Plan, Zonal Development Plan and Development
Plan or required due to local requirements; The planning requirements for the above are given below:
(i) Service Roads:
(a) The minimum width of a service road shall be 7.5m. This service road can serve up to a length of 300m. This will be measured from one wider street to another wider street. If the 7.50m. road ends as a dead end depth of the turn around should be of 15 M. or an equivalent area in another form permitting turn around. No turn around is required if the number of plots served by such road is less than three.
(b) A road which is longer than 300M or serves up to 100 plots/houses or extendable to new areas shall be 12m. wide.
(c) All junctions of service roads shall have sufficient weaving angle. In no case it shall be less than the space arrived at by drawing a quadrant of a circle of 4.5m radius at the edge of the actual road lines leaving the width of pedestrian walks (foot path) and the plot boundaries shall be rounded of by drawing a quadrant of the circle of 2.7m radius at the edge of plot boundaries. It can also be provided but cut in place of rounded corners to be determined by the RMC.
(ii) Other roads :- Arterial/Semi-arterial Roads : The widths of roads shall be as per the Master plan.
(iii) Service lane: In row type of houses and in such areas where sewerage system does not exist a service lane of width 3.5m. shall be provided. The length of such service lane shall be not more than 300m.
33.2.3 Conditions of planning:

33.3 Commercial, business and industrial:
33.3.1 The maximum length permissible for different classification of roads in areas other than residential shall be as indicated below. No roads in these areas shall be less than 12 meter in width.
Class of Width Maximum length Roads permissible M. M. 1. 12 200 2. 18 600 3. 24 and 600 above The width of all Master Plan road shall be as per the width prescribed in the Master Plan.
Alleys shall be provided in commercial and industrial area except where RMC may relax this requirement or when assured provision is made for service access such as off street loading/ unloading and parking consistent with and adequate for the use provided. The width of alleys where provided shall not be less than 6M and no dead end alley shall be permitted unless provided with an adequate turn around facilities.
33.3.3 Junctions :
The layout shall be provided at the junctions of roads in such a way that as far as possible all roads do meet at right angle. Roads meeting at less than that shall not be permitted unless adequate arrangements for the circulation of traffic with desirable weaving length is available.
33.4 Parks/Playgrounds :
33.4.1 The open space in a residential area should be in proportion to the density of that area. To work out an over-all open space exclusively for a active recreation and breathing space the requirement shall be worked out on proposed population density of the area. The requirement of open space shall be divided according to the purpose i.e., tot lot, parks, play field etc. The following criteria may be adopted for arriving at open spaces depending upon density: - Density/per Density/per Open space Acre Hectare in percentage 100 250 15% 150 325 16% 200 500 22% 250 and 625 and 25% above above The open spaces provided in the proposed land use plan of a Master Plan or a Regional Plan shall be over and above this open space and shall be counted under the density ratio mentioned above. In towns where a Master Plan or a Regional Plan has not been prepared, the demarcation and extent of town level open spaces shall be determined by the RMC in consultation with Chief Town Planner.
