Other Buffers
<br />Forestry
<br />Vegetative buffers for forestry use must comply with forestry use standards as provided in Sheet 5 - Use.
<br />Stormwater
<br />Buffers required under chapter 7090 must be consistent with MPCA storm water permit requirements.
<br />* Buffers are not required for: (1) public roads and water access facilities; and (2) public recreation facilities, including scenic overlooks, observation platforms, trails,
<br />docks, boat launching facilities, and beaches with swimming areas within public parks. Vegetation removal necessary for the construction of structures and SSTS
<br />approved under valid permits are also exempt; however, land alteration and stormwater provisions must be met as provided in Sheet 3 - Water Quality.
<br />**Shoreline Buffer Exceptions: (1) invasive species removal or the removal of trees, limbs, or branches that are dead, diseased, or pose safety hazards, as determined
<br />by a forester, arborist, or other qualified LGU representative; and (2) limited clearing and trimming of vegetation within the 50' buffer area is allowed to
<br />accommodate the placement of permitted stairways, landings, and lifts; one access path (not to exceed 8' in width); shoreline recreational use area (not to exceed
<br />25'x 25' on a 300' wide lot, with an extra 25' allowed for each 100' in lot width for PUDs and lots >300' wide, not to exceed 5,000 sq ft total); and permitted water -
<br />oriented structures (not to exceed 120 sq ft), provided that: (a) the screening of structures, vehicles, or other facilities as viewed from the river or OHWL of the
<br />opposite shore, assuming summer, leaf -on conditions, is not substantially reduced; and (b) existing shading of water surfaces is preserved.
<br />***Bluff & Steep Slope Buffer Exceptions: (1) invasive species removal or the removal of trees, limbs, or branches that are dead, diseased, or pose safety hazards, as
<br />determined by a forester, arborist, or other qualified LGU representative; and (2) limited clearing and trimming of vegetation necessary to accommodate
<br />permitted stairways, lifts, and landings; and one access path (not to exceed 8' in width). Additionally, LGUs must evaluate possible soil erosion impacts and
<br />development visibility from the river before issuing a permit for construction of roads and driveways (where avoidance is not reasonable or prudent) and other
<br />structures (including those listed as exceptions to setback provisions) in the SPZ. When determined necessary, conditions must be attached to issued permits to
<br />prevent erosion, preserve vegetation or restore vegetation to a natural state, and screen structures, vehicles, and other facilities as viewed from the surface of the
<br />river and the OHWL of the opposite shore, assuming summer, leaf -on vegetation.
<br />Note on exceptions listed above: Areas cleared of vegetation for the removal of invasive species or dead, dying, and diseased vegetation shall be required to
<br />reestablish native vegetation, either by allowing it to regenerate naturally (no cutting or mowing) or with plantings, subject to a management plan.
<br />DEFINITIONS
<br />Intensive Vegetation Clearing = substantial removal of
<br />trees or shrubs in a contiguous patch, strip, row or block.
<br />Natural State = where vegetation exists in a wild state,
<br />where the condition of the ground and shrub layers and
<br />floristic composition of the plant community is
<br />substantially unaltered by humans, where restoration has
<br />been consistent with commissioner guidelines or local
<br />government approved plans, or where the vegetation has
<br />been unaltered for a least one growing season.
<br />Slope Preservation Zone (SPZ) = land on and within 20' of
<br />bluffs and very steep slopes.
