Redevelopment can expose bottlenecks in old pipes, stations or streets.
Efficiency and peak load can coexist
Shared infrastructure can be efficient overall while still needing capacity at busy nodes.
Sequencing matters
Growth works better when service upgrades and development timing are coordinated.
Scope boundary. This page explains system relationships at a planning level. Real utility, transportation, emergency, structural, electrical, cybersecurity and public-safety decisions require local agencies and qualified professionals.
