<br />C.2. Each LGU and state agency shall prepare plans
<br />and regulations to protect and preserve the
<br />aesthetic qualities of the river corridor, which
<br />provide for the following considerations:
<br />b. Structures. Structure site and location shall
<br />be regulated to ensure that riverbanks,
<br />bluffs, and scenic overlooks remain in their
<br />natural state, and to minimize interference
<br />with views of and from the river, except for
<br />specific uses requiring river access.
<br />F. Dimensional standards and criteria
<br />4. Structure setbacks.
<br />b. All new structures and roads shall meet the
<br />following minimum setbacks:
<br />(1) Rural Open Space district: no structure or
<br />road shall be placed less than 200' from the
<br />normal high water mark, and no less than
<br />100' from blufflines.
<br />(2) Urban Developed and Urban Open Space
<br />districts: the structure or road shall be
<br />placed no less than 100' from the normal
<br />high water mark of the river, and no less
<br />than 40' from blufflines.
<br />(3) Urban Diversified district: the structure or
<br />road shall be placed no less than 40' from
<br />the bluffline.
<br />c. Exceptions to setback provisions shall be:
<br />(1) public safety facilities, public bridges and
<br />their roadway approaches, railroad sidings,
<br />minor public and private roadways serving
<br />water - related uses on the riverfront;
<br />(2) public recreation facilities, scenic overlooks,
<br />public observation platforms, the regional
<br />trail system, docks, boat launching facilities;
<br />(3) approved river crossing of essential service,
<br />essential services distribution systems which
<br />are primarily underground except for
<br />terminal and metering devices not exceeding
<br />6' in height, supporting structures for
<br />transmission crossing spans;
<br />(4) construction of above - ground pumping
<br />stations for sewer lines which shall be
<br />screened from view of river,
<br />(5) reconstruction or restoration of historical
<br />structures or sites on the Inventory of the
<br />State Historical Society or National Register
<br />of Historic Places.

<br />Exceptions
<br />Exceptions:
<br />(1) public safety facilities, public bridges /approaches, railroad sidings, and minor public and private roadways serving river-
<br />dependent uses per the applicable standards in Sheet 56 - Facilities;

<br />(5) structures, districts, and sites on the inventory of the State Historical Society or the National Register of Historical Places,
<br />provided new and redeveloped structures have setbacks compatible with historic character;
<br />(6) one water oriented accessory structure (WOAS) for each riparian lot <300' in width at the OHWL, with one additional WOAS
<br />per each additional 300' of shoreline (not to exceed 12' in height, 120 square feet in area, <10' from the OHWL, not within
<br />the BIZ or SPZ);
<br />(7) aviation safety features, such as navigational lighting fixtures, other navigational structures, and airfield pavements;
<br />(8) shoreline facilities per the applicable standards in Sheet 5a — Uses & Sheet 56 - Facilities);

<br />Setback Averaging:
<br />Where principal structures exist on the adjoining lots on both sides of the proposed building site, the setback may be altered to
<br />conform to the adjoining setbacks. No structures are allowed within the BIZ, SIZ, or SPZ unless specified in the exceptions above.
