Abstract

This work aims to carry out a survey on municipal legislation and other legal management instruments, related to the control and mitigation of urban floods and inundations in medium-sized municipalities in the state of Rio de Janeiro. In this context, 22 municipalities in the range between 100 and 500 thousand inhabitants were surveyed. Among the results obtained, it was found that only 13 municipalities had specific municipal legislation to mitigate the effects of inundations and urban floods. Approximately 59% of the analyzed municipalities had municipal legislation oriented to the local reality. There is a need to increase public policies and government incentives for the expansion of legal provisions in the municipalities analyzed.

Highlights

The occupation and waterproofing of soils as a result of urbanization collaborate with the aggravation of urban flood events and the urban environment degradation (TUCCI, 2007a; MIGUEZ; REZENDE; VERÓL, 2015)
The objective of this work is to conduct a documentary research on legal management instruments related to the control and mitigation of urban floods, in addition to perform an investigation on the use of structural compensatory techniques in medium-sized municipalities in the state of Rio de Janeiro

Summary

Introduction

The occupation and waterproofing of soils as a result of urbanization collaborate with the aggravation of urban flood events and the urban environment degradation (TUCCI, 2007a; MIGUEZ; REZENDE; VERÓL, 2015). 25% of municipalities have a master plan that includes flood prevention measures and only 26% of the municipalities declared to have a Land Use and Occupation Law foreseeing these occurrences (IBGE, 2018) Given this scenario, it is extremely important to know the legal management instruments in Brazilian states and municipalities. There are limited studies on the panorama of municipal management in relation to flood mitigation and, normally, their main focus are metropolises and large municipalities, having as examples the works of Fonseca et al (2006) and Fontes da Luz et al (2020) These works deal only with structural flood mitigation techniques, such as rainwater reservoirs.
