Government to Address Waterlogging: New Laws to Remove Encroachments, Streamline Flow

Due to heavy rainfall in Vadodara, Ahmedabad, and Jamnagar, floodwaters have entered people’s homes and remained for an extended period. The initial study conducted by the government found that many structures, including buildings and roads, were erected directly in the path of water flow, leading to these issues. Following this study, the government has decided to remove constructions, including illegal buildings, from areas prone to flooding in cities and highways.

Plans for Addressing Flooding and Building Regulations

Additionally, for regular constructions, technical solutions will be explored if they pose an obstruction to water flow. The plan for TP schemes will now include a study of land contours and slopes before drafting. Instead of just considering primary facilities, future plans will involve a comprehensive study of water slopes and flow paths to prepare integrated TP schemes. Before finalizing the plan, it will be ensured that city roads align with water flow rather than cutting across it.

Technical Solutions for Existing Structures

If regular constructions approved under previous TP schemes or impact fees obstruct water flow, solutions will be sought through technical studies instead of demolishing the buildings. Flood management and stormwater drainage structures in such areas will be improved.

Study of Rainfall Patterns

The government has noted that heavy rainfall can occur without warnings and can be very intense in a short period. Thus, a study of rainfall patterns will be conducted to identify and address locations prone to water accumulation.

Upcoming Changes and Regulations

• Constructions obstructing water flow will not be permitted.
• Impact fee constructions that block water flow will be studied for alternative solutions.
• TP schemes will consider land contours and slopes.
• New TP schemes will avoid constructing roads or buildings that obstruct water flow.
• TP authorities will consult with contour departments.
• Changes in GDCR-DP regarding building elevations and compound walls will be made.
• Flood management and stormwater drainage structures will be strengthened.
• Locations prone to water accumulation will be identified and recorded.
• Facilities for rapid drainage in flood-prone areas will be established.
• Drainage facilities will be improved based on rainfall patterns.
• Buildings obstructing water flow will not be regularized.

Identification and Regulation of Flood-Prone Areas

The government has instructed authorities to identify flood-prone areas in various cities. In developing areas, special attention will be given to prevent construction permissions. Plans are being made to provide solutions to ensure water drains quickly.

Changes in GDCR and Development Plans

After these events, new GDCR regulations and development plans will include considerations for flood-prone areas. Amendments in GDCR and development plans are expected, incorporating issues related to building elevations and drainage systems.

IIT Study on Urbanization and Flooding in Gujarat

An IIT Gandhinagar study has highlighted that excessive urbanization and adverse environmental conditions have exacerbated flooding issues in Gujarat. The study’s findings indicate that the state’s flood crisis has become more severe due to these factors.
