What must be included in construction record drawings regarding stormwater management?

Construction record drawings regarding stormwater management must include accurate and detailed documentation related to the stormwater systems that are installed on-site. The correct answer highlights the importance of maintaining records that reflect the design, modifications, and configuration of the stormwater management systems.

These records provide critical information for future inspections, maintenance, and potential upgrades or changes to the system. By keeping records perpetually, or at least until the facility is removed, stakeholders ensure that there is an ongoing reference that can aid in evaluating the effectiveness of the stormwater management practices over time and complying with regulatory requirements. Such records help address any possible issues that may arise concerning the system's performance or environmental impacts.

In contrast, geographic diversity assessments, permanent monitoring stations, and historical rainfall data, while useful in specific contexts, do not serve the same purpose in documenting the constructed elements of stormwater management systems. They focus on broader environmental patterns or compliance monitoring rather than the specific configurations and operational details that are essential for ongoing facility management.
