After scrutinising the civic body’s existing land use (ELU) survey and comparing it with ground reality, citizens’ groups, NGOs and other surveyors have spotted at least 550 errors in the ELU maps.
Among the most glaring errors are heritage structures such as the Gateway of India and the Royal Bombay Yacht Club being marked as open spaces and Prithvi theatre being classified for residential use.

The ELU survey will form the basis for the new development plan, which is a blueprint for the city’s development for the next 20 years. Mistakes in the ELU will reflect in the 2014 DP.

The BMC has extended the last date for submitting the scrutiny reports to January 24, and the Urban Design Research Institute, which originally found 1,200 discrepancies, is compiling a fresh list and has spotted 40 errors. While BMC chief Sitaram Kunte said he was attending a workshop and won’t be able to comment, DP department officials refused to respond.
