1. All public improvements shall be constructed in compliance with the standards and specifications established by this Section 146-4.3, Section 146-5.4.2 (Subdivision of Land), the Aurora City Code and adopted regulations, including all design standards and requirements in the Aurora Roadway Design and Construction Specifications Manual, the Aurora Public Utility Improvement Rules and Regulations Regarding Standards and Specifications, the Aurora Water Standards and Specifications Regarding Water, Sanitary Sewer and Storm Drainage Infrastructure, and the Parks, Recreation and Open Space Dedication and Development Criteria Manual.

2. No subdivider shall be relieved of the duty to construct public improvements for the subdivision until all public improvements are constructed, approved, and accepted by the City Engineer.

3. The subdivider shall submit plans, profiles, and specifications for the construction of all public improvements for which no specifications or standards are established by Aurora. Such plans, profiles, and specifications shall be prepared and authenticated over the seal of a professional engineer, duly licensed to practice in Colorado.

4. A subdivider may, upon City approval, construct public improvements to standards higher than the City's specifications for the design and construction of roadways established by the City Engineer. Before the City approves such higher standards, the subdivider shall submit maintenance plans relating to such public improvements.

1. In addition to the 100-year floodplain, other lands subject to flooding or land that if developed or improved would cause improved areas within the City to be subject to flooding shall not be platted for residential occupancy or for any other use that may increase danger to health, life, or property, or aggravate the flood hazard to surrounding properties.

2. All subdivisions shall include a storm water management system designed in accordance with the City of Aurora Public Utility Improvements Rules and Regulations Regarding Standards and Specifications and the City of Aurora Storm Drainage Design and Technical Criteria and the Aurora Water Standards and Specifications Regarding Water, Sanitary Sewer and Storm Drainage Infrastructure and approved Master Plans. The storm water management system shall provide adequate drainage and flood control as well as provide structural and/or nonstructural Best Management Practices for the control of storm water quality, as required by the ASDDTC and Colorado Department of Public Health and Environment (CDPHE).

3. The storm water management system in each subdivision shall be designed to integrate with required outdoor common areas, designated parkland and open space areas, green space, and landscaped areas as described in Section 146-4.7.6 (Site Design for Low Impact Development – (LID)), to promote the use of natural systems to manage storm water, and to reduce the cost of construction and maintenance of pipes, culverts, and other hard infrastructure, to the maximum extent practicable.

4. Drainage outfalls shall be consolidated so that they may be served by area-wide or regional ponds or storm water treatment facilities to the maximum extent practicable.
