1.1 The basic objective of land use zoning is to regulate land use in hazard prone areas to minimise   the   damage   caused   to   the   habitat,   as   a   result   of   natural   hazards   viz. earthquakes,  cyclonic  storms  and  floods  which  recur  from  time  to  time.  Land  Use Zoning, therefore, aims at determining the locations and the extent of areas likely to be adversely affected by the hazards of different intensities and frequencies, and to develop such areas in a fashion that the loss to the development is reduced to the minimum.

1.2 Land Use Zoning envisages certain restrictions on the indiscriminate development of the "unprotected"  hazard  prone  areas  and  to  specify  conditions  for  safer  development  by protecting the area from severe losses. In the former case, boundaries of different zones
are to be established to prevent unrestricted growth there


2.1Areas covered under Development Plan
The  guidelines  for  Land  Use  Zoning  in  Hazard  Prone  Areas  are  to  be  taken  into consideration  while  formulating  the  Development  Plan  and  Area  Plan  under  the  Town Planning and Urban Development Act.

2.2Areas not covered under Development Plan
In such areas, these guidelines may be issued to the various local bodies, Municipalities, Individual Areas and Panchayats, enabling them to act while siting various development projects and deciding on construction of buildings, etc.


3.1Earthquake Prone Areas

a. Intensities  of  VII  or  more  on  Modified  Mercalli  or  MSK  intensity  scale  are considered moderate to high. Areas under seismic zone III, IV and V as specified in IS 1893 are based on intensities VII, VIII, IX or more. Therefore, all areas in these three zones will be considered prone to earthquake hazards.

b. In these zones the areas which have soil conditions including the level of water table favourable to liquefaction or settlements under earthquake vibrations will have   greater   risk   to   buildings   and   structures   which   will   be   of   special consideration under Land Use Zoning.

cUnder these zones, those hilly areas which are identified to have poor stability conditions and where landslides could be triggered by earthquake or where due to  prior  saturated  conditions,  mud  flow  could  be  initiated  by  earthquakes  and where avalanches could be triggered by earthquake will be specially risk prone.

d.Whereas, earthquake hazard prone areas defined in 'a' above are identified on the

map given in IS 1893 to  small scale and more easily identified in the larger scale statewise maps given in the Vulnerability Atlas of India, the special risky areas as defined in 'b' and 'c' above, have to be determined specifically for the planning area under consideration through special studies to be carried out by geologists and geo-technical engineers.

3.2 Cyclone Prone Areas

a. Areas  prone  to  cyclonic  storms  are  along  the  sea  coast  of  India    where  the cyclonic  wind  velocities  of  47  meter  per  second  or  more  are  specified  in  the Wind Velocity Map given in IS 875 (part 3) to a small scale and easily identified in  the  Vulnerability  Atlas  of  India  where  the  Maps  are  drawn  statewise  to  a larger scale.

b. In  these  cyclone  prone  areas,  those  areas  which  are  likely  to  be  subjected  to heavy  rain  induced  floods  or  to  flooding  by  sea-water  under  the  conditions  of storm  surge,  are  specially  risky  due  to  damage  by flood  flow  and  inundation under water.

c. Whereas, areas under 'a' are easily identified, those with special risk as under 'b' have  to  be  identified  by  special  contour  survey  of  the  planning  area  under consideration and study of the past flooding and storm surge history of the area. These studies may have to be carried out through the Survey of India or locally appointed  survey  teams,  and  by  reference  to  the  Central  Water  Commission, Government of India and the concerned  department of Gujarat State.

3.3 Flood Prone Areas

a. The flood prone areas in river plains (unprotected and protected by bunds) are indicated in the Flood Atlas of India prepared by the Central Water Commission and reproduced on larger scale in the statewise maps in the Vulnerability Atlas of India.

b.Besides the above areas, other areas can be flooded under conditions of heavy intensity   rains,   inundation   in   depressions,   backflow   in   drains,   inadequate drainage, failure of protection works, etc.

c. Whereas, the flood prone areas under 'a' are identified on the available maps as indicated, the areas under 'b' have to be identified through local contour survey and study of the flood history of the planning area. Such studies may be carried out  through  Survey  of  India  or  local  survey  teams,  and  by  reference  to  the Central Water Commission and the concerned department of Gujarat State.

3.3. Land Use Zoning for Flood Safety

Some important considerations for regulating the land use in the planning areas are given below:i.Every  settlement  needs  some  open  areas  such  as  parks,  play-grounds,  gardens etc.   In  one  way  it  will be  possible  to develop  such  areas  by  restricting  anybuilding activity in vulnerable areas. Such a development will be in the interest of providing proper environment for the growth of such settlement.

ii.On the same analogy, certain areas on either side of the existing and proposed drains  (including  rural  drains)  should  be  declared  as  green  belts  where  no building  or  other  activity  should  be  allowed.  This  will  not  only  facilitate improvements  of  these  drains  in  future  for  taking  discharges  on  account  of growing  urbanisation,  but  will  also  help  in  minimising  the  damage  due  to drainage  congestion  wherever  rainfall  of  higher  frequency  than  designed  is experienced.  These  green  belts  at  suitable  locations  can  also  be  developed  as parks and gardens.

iii. In   the   existing   developed   areas,   possibilities   of   protecting/   relocation/ exchanging the sites of vital installation like electricity sub-station/power houses, telephone exchange, etc. should be seriously examined, so that these are always safe  from  possible  flood  damage.  Similarly,  the  pump  station  the  tubewells meant for drinking water supply should be raised above the high flood levels.

iv.Similarly, possibility of removing or bypassing buildings/structures obstructing existing natural drainage lines should be seriously considered. In any case, with immediate  effect  unplanned  growth  can  be  restricted  so  that  no  construction obstructing natural drainage or resulting in increased flood hazard is allowed.


Following two alternatives can be adopted for dealing with the disaster risk problems.
aLeaving the area unprotected. In this case it will be necessary to specify Land Use Zoning for various development purposes as recommended under Para 6.

b. Using  protection  methods  for  the  areas  as  a  whole  or  in  the  construction  of buildings, structures and infrastructure facilities to cater for the hazard intensities likely in the planning area as recommended under Appendix-B.

It will be appropriate to prioritise buildings, structures and infrastructures in terms of their importance from the point of view of impact of damage on the socio-economic structure of the society. Prioritisation scheme is suggested under Para 5.


In regard to Land Use Zoning, different types of buildings and utility services may be grouped under three priorities as indicated below.
Priority  1.  Defence  installation,  industries,  public  utilities  like  hospitals,  electricity installations,    water    supply,    telephone    exchange,    aerodromes,    railway    stations, commercial  centres,  libraries,  other  buildings  or  installations  with  contents  of  high economic value.

Priority 2. Public institutions, Government offices, universities and residential areas. Priority 3. Parks, play grounds, wood lands, gardens


Appendix - B


(Building Regulation No. 32.1)


i. In those areas where there are no dangers of soil liquefaction or settlements or landslides, all building structures and infrastructures should be designed using the relevant Indian Standards as provided in the Building Regulations and the National Building Code

ii  Soils subjected to liquefaction potential under earthquake shaking, can be improved by compaction to desired relative  densities, so as to prevent the possibility of liquefaction.

iii. Buildings and structures could be founded on deep bearing piles going to non-liquefiable dense layers.

iv. Steep slopes can be made more stable by terracing and construction of retaining walls and breast walls, and by ensuring   good drainage of water so that the saturation of the hill-slope is avoided.

iii. other  appropriate  engineering  intervention  to  save  the  building  structures  or infrastructure from the fury of the earthquake.

Note The protective action given under (ii) to (v) will usually involve large amount of costs and should only be considered in the case of large and costly structures. For ordinary buildings the cost  of  improvement of  the  site    will  usually  be  uneconomical,  hence  bad  sites  should  be excluded by Land Use Zoning.


i.Buildings, structures and infrastructures in the cyclone prone areas should be designed according to the Indian Standards and Guidelines as provided in the Regulations and the National Building Code.

ii. Light utility structures used for electrical transmission and distribution, and towers for communications,   chimney   stacks   of   industrial   structures   require   special   design considerations against the cyclonic wind pressures, suctions and uplifts.

iii.In case the buildings, structures and infrastructures are founded on marine clay deposits it will be advisable to adopt either under-reamed piled foundations, or individual column footing  with  a  reinforced  concrete  beam  located  at  the  level  of  the  ground,  or  a continuous reinforced concrete strip footing.

iv. Wherever,  the  top  soil  could  become  slushy  due  to  flooding,   the  top  layer  of  30  cm depth of soil should not be considered for providing lateral stability

v. In storm surge prone areas, it will be preferable to construct the community structures, like  schools,  cyclone  shelters,  etc.  by  raising  the  level  of  the  ground  protected  by provision of retaining walls at sufficient distance away from the building, taken to such depth that no erosion takes place due to receding storm surge.   Alternatively, construct the  community  structures  on  stilts  with  no  masonry  or  bracing  upto  the  probable maximum surge level.
