Noise, vision corners and drainage

Noise, vision corners and drainage. (1) Noise. When noise barriers are warranted under the criteria specified in ch. Trans 405 , the department is not responsible for any noise barriers for noise abatement from existing state trunk highways or connecting highways. Noise resulting from geographic expansion of the through-lane capacity of a highway is not the responsibility of the owner, user or land divider. In addition, the following notation shall be placed on the land division map: (2) Vision corners. The department may require the owner to dedicate land or grant an easement for vision corners at the intersection of a highway with a state trunk highway or connecting highway to provide for the unobstructed view of the intersection by approaching vehicles. The owner shall have the choice of providing the vision corner by permanent easement or by dedication. If the department requires such a dedication or grant, the owner shall include the following notation on the land division map: (3) Drainage. The owner of land that directly or indirectly discharges stormwater upon a state trunk highway or connecting highway shall submit to the department a drainage analysis and drainage plan that assures to a reasonable degree, appropriate to the circumstances, that the anticipated discharge of stormwater upon a state trunk highway or connecting highway following the development of the land is less than or equal to the discharge preceding the development and that the anticipated discharge will not endanger or harm the traveling public, downstream properties or transportation facilities. Various methods of hydrologic and hydraulic analysis consistent with sound engineering judgment and experience and suitably tailored to the extent of the possible drainage problem are acceptable. Land dividers are not required by this subsection to accept legal responsibility for unforeseen acts of nature or forces beyond their control. Nothing in this subsection relieves owners or users of land from their obligations under s. 88.87 (3) (b) , Stats.
