The challenges related to sanitation and water management in new urban communities have contributed to the emergence of visions of Integrated Urban Water Management (IUWM) and Water Sensitive Urban Design in cities worldwide to keep pace with these subtle changes the shape of the urban environment. This research paper aims to monitor the main obstacles and challenges facing residents of new cities in Egypt and the environmental impacts resulting from those challenges in the urban context. A questionnaire was conducted among a group of the population. This study took the economic houring model for low-income people in the 6th of October City in Egypt as a case stud. As a result, the study found that the main challenges facing the residents of these areas and their impacts are: I 1) Lack of regulag maintenance. 2) Health risks to the population. 3) Damaging of public parks and gardent. 4) Pollution of the surounding environment, including soil and water. 5) Lack of state funding for maintenance and Limited financial resources available for projects in this type of housing. 6) Lack of government engagement in preparing programs to raise population awareness and clarity in environmental goals and quality of life policies. 7) Lack of community initiatives to participate in decision-making. 8) Lack of political guidance on planning processes for sustainable infrastructure.

Introduction Nature-based solutions are increasingly recognized as vital components of urban resilience strategies, particularly within the framework of green infrastructure. This study aims to propose an approach that fosters symbiosis between green and gray infrastructure to address the challenges posed by climate change in urban environments.Methods We conducted a comprehensive review of guidelines and scientific literature to inform the selection of species and the design of root containers for urban tree planting. Additionally, we performed a multicriteria analysis and assessed water comfort to guide decision-making regarding species selection in specific city areas.Results The methodology was applied to a case study in Bogota, yielding insights applicable to any city with basic knowledge of suitable species for planting in built public spaces. Crucial criteria for selecting local species for sidewalks were identified, including size, permeability, soil compaction characteristics, and climatic adaptability. A list of desirable species adapted to all humidity zones of the case study city was generated. Hydrological sizing methods proposed are contingent upon both the species to be planted and the geometry of the streets.Discussion The approach and findings presented in this study promote the development of trees and their ecosystem services while mitigating potential damage to surrounding infrastructure.Conclusion Implementing strategies that facilitate symbiosis between green and gray infrastructure contributes to urban resilience and aids in climate change adaptation efforts.
