Why is it important to have a comprehensive stormwater management plan in place?

Having a comprehensive stormwater management plan is essential primarily to minimize negative environmental impacts and control flooding. This plan outlines measures to manage the quantity and quality of stormwater runoff, which can lead to erosion and sedimentation if not properly handled. Effective management practices help protect water bodies from pollutants that can be washed into them during storm events, thus preserving water quality and aquatic ecosystems. Furthermore, by controlling stormwater runoff, the plan mitigates flooding risks, safeguarding infrastructure and enhancing public safety.

The other choices, while relevant to different aspects of land use and development, do not encapsulate the primary purpose and importance of a stormwater management plan in the context of environmental protection and flood control. The focus on environmental stewardship and flood risk management is what makes option B the most comprehensive choice in this scenario.
