The KEDM shall govern all new construction and upgrading of facilities both in the right‑of‑way and on‑site for: transportation‑related facilities; storm drainage facilities and stream channel improvements; sewer and water improvements; and park, recreation, and open‑space facilities used by the public. No construction of public improvements shall commence prior to City approval of the required design reports and construction plans.
