Setback from any primary road be at least 200 metres from the road edge.
The industrial estate should be separated from existing and proposed residential areas by at least 150 metres (medium sized units of light industry and warehouses) or at least 500 metres (large units of light and general industry)
Small scale and non-offending cottage industries may be allowed in low-income residential areas. They may operate within dwelling units or a separate Nursery Industrial Estate may be provided for them. These nursery estates may vary in size, from about 0.4 hectares to about 3 hectares.
The industrial areas should have access to power and water supplies.
The industrial areas should also have good access to primary and secondary
roads, but no access to individual plots from primary roads.
In order to achieve the flexibility as an in-built character of an industrial area, it is proposed that a dominantly Modular Approach be adopted for physical planning. The Modular Approach permits the adoption of an optimum size of space unit, various numbers of which can be combined to generate plots of varying sizes. The dimensions of the basic module may be 25m x 50m. This versatile size with a length/breadth ratio of 2.0 permits its combination into a large number of industrial plots of varying sizes. Fig. 5.2 gives six basic combinations.
The Modular Approach, however, may not be strictly followed. Corner plots and those at the peripheries may have non-modular dimensions.
Industrial areas should be planned in accordance with following guidelines:
Plots of smaller size should be grouped as to separate small workshops from large scale industry.
Larger plots should be positioned in the most visible locations.
Where site conditions permit, a grid pattern road layout should be used, with staggered T-junctions on the local roads in the industrial area.
The following are partial guidelines to be considered while selecting locations for industrial estates.
Areas of reasonably flat land to allow large plots and buildings with large spans.
Areas which do not have substantial natural vegetation.
On the downside of existing or proposed residential areas for the prevailing wind; and
Separated from orchards and other valuable agricultural areas.
