Bluffs. <br />(a) No vegetation shall be removed from, nor shall construction activities encroach on, bluff impact zones within <br />the shoreland overlay district that would result in erosion, bank slumping, or a change to the topography of <br />any shoreland, public waters, or wetland area, except by permit granted by the city council. <br />(1) Minor removal of trees, limbs, or other vegetation which is dead, diseased, or pose safety hazards is <br />permitted without permit. Where removal of the dead, diseased, or hazardous vegetation may result in <br />erosion or bank slumping, such removal may be allowed by permit issued by the city building official. <br />(2) An erosion control and sedimentation plan adequate to protect the bluff and adjacent property from <br />damage is required for approval by the building official prior to a permit being issued for construction <br />activities or vegetation removal in bluff impact zones. <br />(3) No structures except stairways and landings are allowed in bluff impact zones located in the shoreland <br />overlay district. <br />(Prior Code, § 1175-040.1) <br />Sec. 90-170. Public waters. <br />(a) No waste shall be discharged into a storm sewer except clear and unpolluted water. No connections shall be <br />made to a public storm sewer except by permit from the city engineer. All waste discharged into the city's <br />sanitary sewer shall meet the requirements established by ordinance. <br />(b) No waste shall be discharged into public waters that violates state law. <br />(c) The placement of riprap, retaining walls, or other similar structures along the shoreline or embankment of <br />public waters requires a conditional use permit, except the placement of natural rock riprap, including <br />associated grading of shoreline and placement of a filter blanket, is allowed by a certificate of zoning <br />compliance where: <br />(1) The finished slope does not exceed three feet horizontal to one foot vertical. <br />(2) The height of the riprap does not exceed three feet above the ordinary high-water level. <br />(Prior Code, § 1175-050.1) <br />Sec. 90-171. Minimum building elevations. <br />In order to provide a reasonable assurance that buildings will not be flooded by surface or ground waters <br />during a regional flood, the following minimum standards are established for the construction of structures in all <br />zoning and overlay districts of the city: All basement floors, or first floor if there is no basement, shall be <br />constructed at an elevation above the regulatory flood protection elevation, or four feet above the ordinary high <br />groundwater elevation, whichever is higher, unless floodproofed in accordance with subsection 90-138(5). <br />(Prior Code, § 1175-060.1; Ord.
