(a) Green Infrastructure Techniques. The City encourages the use of green infrastructure techniques because of their connection to sustainable development practices and environmental quality. The proper use of green infrastructure can improve storm water run-off quality, decrease run-off volume, protect downstream streams and rivers, and create more interesting places to live. The following green infrastructure techniques can be incorporated into new subdivisions with approval from the City Engineer:
(1) Narrower pavement widths;
(2) Narrower right-of-way widths;
(3) Grassy swales and shoulders without curb and gutter;
(4) Pedestrian walkways that do not constitute a pedestrian circulation system equal to sidewalk on both sides of the street;
(5) Permeable pavers (e.g., pavers, permeable concrete, permeable asphalt pavement);
(6) Bioretention swales;
(7) Planter boxes; and
(8) Curb extensions.
(b) Criteria for Green Infrastructure Waivers. The City Engineer may grant a green infrastructure waiver for use of the green infrastructure techniques identified in Subsection 1167.18(a) provided:
(1) The techniques are proposed to utilize the landscape's ability to reduce, slow, filter, and/or absorb storm water run-off from streets, parking lots, and buildings;
(2) The techniques are consistent with best management practices; and
(3) The technique has been designed by a professional engineer and is accompanied by documentation stating that the proposed technique does not pose a threat to public safety.
