Improvement Plans

All on-site and off-site Civil Improvement plans must undergo a review and approval process. LDE thoroughly checks these plans for conformance to the City Standards, municipal code, state water and health regulations, and overall sound engineering practices. In addition, LDE reviews on-site storm drainage design for conformance to the current requirements as outlined in the City Standards.
