BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF MINNESOTA:

subdivision 1, is amended to read: 
    Subdivision 1.  [SCOPE.] The definitions in this section

    Sec. 2.  [103B.3365] [WATER RETENTION.] 
    Subdivision 1.  [IMPERVIOUS SURFACE OVER ONE ACRE.] New 
development that covers or replaces surface vegetation with an 
impervious surface of one acre or more may not take place 
without water retention devices or areas being required for the 
development site by the local unit of government. 
     Subd. 2.  [EXEMPTIONS.] Linear projects such as sidewalks, 
paths, trails, and the reconstruction, repair, reconditioning, 
or resurfacing of existing roads or impervious surfaces are 
exempt from this section. 
    Subd. 3.  [APPLICATION.] This section does not preclude a 
local unit of government from imposing more stringent 
requirements authorized by law on the development site. 
    Subd. 4.  [LOCAL WATER PLANS.] Each water management plan 
required by sections 103B.201 to 103B.355 must specify controls 
that utilize the best available technology to minimize off-site 
stormwater runoff, maximize overland flow and flow distances 
over surfaces covered with vegetation, increase on-site 
infiltration, replicate predevelopment hydrologic conditions as 
nearly as possible, minimize off-site discharge of pollutants to 
ground and surface water, encourage natural filtration 
functions, and reduce mosquito breeding habitat. 
    Subd. 5.  [GUIDELINES.] By January 1, 1992, the board of 
water and soil resources must develop guidelines to assist local 
units of government in implementing subdivision 1.
