R  560.301   Definitions.
  Rule 301. As used in this part:
  (a) "A 100-year flood" means a flood with a magnitude  which   has   a   1% 
chance of occurring or being exceeded in any given year.
  (b) "Datum" means the basis from which elevations are measured.
  (c) "Flood" means a temporary increase in the stage of  a  watercourse   or 
lake resulting in the inundation of lands not normally covered  by  water.
  (d) "Floodplain" means that area of land adjoining a  watercourse  or  lake 
which will be inundated by a 100-year flood.
  (e) "Lake" means a natural or artificial body of water   with   a   surface 
area of 5 acres or more measured at its normal stage,  including  the   great 
lakes.
  (f) "Watercourse" means an open conduit either  naturally  or  artificially 
created which periodically or continuously contains moving water  draining an 
area of not less than 2 square miles.  The  point  of  measurement   of   the 
drainage area shall be the downstream limit of the subdivision.

R  560.302   Field survey data.
  Rule 302. (1) The purpose of this rule is to prescribe  field  survey  data 
required before submittal of a preliminary plat.
  (2) A proprietor shall furnish, on request by the  department  of   natural 
resources, plotted valley cross-sections from a control  point  downstream of 
the  proposed  plat  to  the  upstream   limits   of   the   plat   for   any 
watercourse through or adjacent to the area to be  subdivided.  The   spacing 
between the cross-sections shall be frequent enough to define the  changes in 
the hydraulic properties of   the   watercourse.   The   location   of   each 
cross-section shall be shown on a topographic map and elevations shall  be at 
either national geodetic  vertical  datum  or   international   Great   Lakes 
datum. The required field surveys shall be conducted under the supervision of 
an engineer or land surveyor licensed in this state.
  (3) A proprietor shall furnish, on request by the  department  of   natural 
resources, current water surface elevations and past  high  water  elevations 
for any lake which is within or is adjacent to the area to be  subdivided.
A determination of the drainage area contributing runoff to the  lake  and an 
engineering sketch of any water  level  control  structures   may   also   be 
required. All elevations shall be at national geodetic  vertical   datum   or 
international Great Lakes datum.  The  required  field   surveys   shall   be 
conducted under the supervision of an engineer or land  surveyor  licensed in 
this state.
  (4) If the subdivision is affected by a 100-year  floodplain,  a  permanent 
benchmark based on either of the datums listed in subrules (2)  and  (3)   of 
this rule shall be established within the plat boundaries  and  described  on 
the preliminary plat.  This  benchmark  shall  be   established   under   the 
supervision of an engineer or land surveyor licensed in this state.

  History: 1979 AC; 1988 AACS.


R 560.303  Floodplain limits; adoption of floodplain delineation reports by
  reference.
  Rule 303. (1) The purpose of this rule is to prescribe methods to  be  used 
to define floodplain limits on lakes and watercourses.
   (2)  The  department  of  environmental  quality  has  approved  published 
floodplain delineation reports, then the 100-year  flood  identified  in  the 
reports shall be used to define the limits of the floodplain  for  the  lakes 
and watercourses covered by the reports.   The  department  of  environmental 
quality shall maintain  the  reports  and  review  them  for  accuracy.   The 
department of environmental quality shall  maintain  list  of  amendments  or 
revisions to the floodplain maps contained in the reports.  Upon request, the 
department of environmental quality shall provide the reports at  no  cost.

R 560.304   Building in areas affected by floodplains.
   Rule 304. (1) The purpose of this rule is to prescribe  minimum  standards 
for a new development  for  residential  purposes  and  occupancy  within  or 
affected by a floodplain.
  (2) A proprietor shall file and record with the final plat restrictive deed 
covenants that state, in perpetuity, that no filling  or  occupation  of  the 
floodplain area will  be  allowed  without  approval  of  the  department  of 
environmental quality and that any building used or capable of being used for 
residential purposes and occupancy within or affected by the floodplain shall 
comply with all of the following requirements:
  (a) Be located on a lot having a minimum buildable  site  of  3,000  square 
feet of its area at its  natural  grade  above  the  elevation  of  the  line 
defining the floodplain limits.
The buildable site shall exclude all setbacks and easements.
  (b) Be served by streets within the proposed  subdivision  having  surfaces 
not lower than 1 foot below the elevation defining the floodplain limits.
  (c) Have lower floors, excluding basements, not lower  than  the  elevation 
defining the floodplain limits.
  (d) Have openings into the basement not lower than the  elevation  defining 
the floodplain limits.
  (e) Have basement walls and floors, if below  the  elevation  defining  the 
floodplain limits, that are watertight and designed to withstand  hydrostatic 
pressures from a water level equal to the elevation of the  contour  defining 
the floodplain limits following methods and procedures outlined in chapter  5 
for type A construction and  chapter  6  for  class  1  loads  found  in  the 
publication entitled "Flood Proofing Regulations," EP 1165 2 314, prepared by 
the office of the chief of engineers, United  States  Army,  Washington,  DC, 
March 1992.   Figure  6  on  page  14-5  of  the  regulations  shows  typical 
foundation drainage and waterproofing details.  This document is  adopted  by 
reference in these rules and is available, at no cost, from the Department of 
Environmental Quality, Land and Water Management Division,  P.O.  Box  30458, 
Lansing, Michigan 48909-7958,  or  the  Department  of  the  Army,  Corps  of 
Engineers, Publications Depot, 890 S. Pickett, Alexandria, Virginia 22304.
  (f) Be equipped with a positive means of preventing sewer backup from sewer 
lines and drains that serve the building.
  (g) Be properly anchored or weighted to prevent flotation.
  (3) The requirement that the building site have its natural grade above the 
floodplain limit in subrule (2) (a)  of  this  rule  may  be  waived  if  the 
building site is to be filled, the requirements of section 194(c) of the  act 
and sections 3104, 3105, 3106, 3107, and 3108 of part 31 of Act  No.  451  of 
1994, being SS324.3104, 324.3105, 324.3106, 324.3107,  and  324.3108  of  the 
Michigan Compiled Laws, sections 30102 and 30106 of part 301 of Act  No.  451 
of the Public Acts of 1994, being SS324.30102 and 324.30106 of  the  Michigan 
Compiled Laws, and sections 30304 and 30311 of part 303 of Act No. 451 of the 
Public Acts of 1994, being SS324.30304 and 324.30311 of the Michigan Compiled 
Laws, where applicable, are met, and any 1 of the following occurs:
  (a) The lowest floor, including the basement, will be constructed above the 
100- year floodplain elevation.
  (b)  A licensed professional engineer  schooled  in  the  science  of  soil 
mechanics states all of the following:
  (i) That the building site has been filled with soil of a  type  and  in  a 
manner that hydrostatic pressures are not exerted upon the basement walls  or 
floor while the watercourse is at or below the 100-year flood elevation.
  (ii) That the placement of the fill will prevent settling of  the  building 
or buckling of floors or walls.
  (iii) That the building is equipped with a  positive  means  of  preventing 
sewer backup from sewer lines and drains that serve the building.
  (c) A licensed professional engineer or  architect  certifies  all  of  the 
following:
  (i) That the basement walls and floors are designed to be watertight and to 
withstand hydrostatic pressure from a water level equal to the 100-year flood 
elevation.
  (ii) That  the  building  is  properly  anchored  or  weighted  to  prevent 
flotation.
  (iii) That the building is equipped with a  positive  means  of  preventing 
sewer backup from sewer lines and drains that serve the building.
  (4)  If the natural floodplain area is altered  through  the  placement  of 
fill or the watercourse is relocated or enclosed  and  the  community  within 
which the subdivision is located is  a  participant  in  the  national  flood 
insurance program, then the developer shall apply for and receive a letter of 
map revision based on fill  from  the  federal  emergency  management  agency 
before recording the final plat.
