2. Why is DCR
required?
Regulation is necessary to ensure planned development
DCR is must for every growing city because the area
immediately beyond the city limits is often a source of
health hazard to the city and generally under no strict
control of an efficient local authority
To control the private development as per the required
standards in relation to public health, safety and
convenience.
To encourage private interest along with public interest in
all aspects of development.
To prevent the conflicting demand and misuse of land.
To control and prevent overcrowding on land.
Development control is statutory in nature and the
planning authority has the power to punish the defaulters.

smoke etc.
4)To control land development
5)Material types control

42. INFERENCES
Though The Setbacks Have Been Compromised Upon, It
Might Not Cause Any Huge Problems For The Time Being
As The Site Is Almost In A Vacant Residential Area With
Inhabited Land Around.
Parking Is Not Sufficient For Four Wheelers And Is Visible
Since The Vehicles Are Parked In The Side Street Lane.
Too Much Of Height Relaxation And Regulation.
Electric Poles At A More Prescribed Distance And Is
Actually Good -Aesthetics Wise And Functionality Wise.
