Saint Paul Legislative Code § 68.274
in effectSec. 68.274. - Stormwater management.
(a) In the bluff impact zone, storm water management facilities are prohibited, except by permit if:
(1) There are no alternatives for storm water treatment outside the bluff impact zone on the subject site;
(2) The site generating runoff is designed so that the amount of runoff reaching the bluff impact zone is reduced to the greatest extent practicable;
(3) The construction and operation of the facility does not affect slope stability on the subject property or adjoining properties; and
(4) Mitigation based on the best available engineering and geological practices is required and applied to eliminate or minimize the risk of slope failure.
(b) In the water quality impact zone, development that creates new impervious surface, as allowed by exemption in division 9, or fully reconstructs existing impervious surface of more than ten thousand (10,000) square feet requires a storm water permit. Multipurpose trails and sidewalks are exempt if there is down gradient vegetation or a filter strip that is at least five (5) feet wide.
(c) In all other areas, storm water runoff must be directed away from the bluff impact zones and unstable areas.
