CONSTRUCTION SEQUENCING
1. INSTALLATION OF SILT FENCE OR BIO -ROLL AROUND SITE
2. DEMOLITION OF EXISTING STRUCTURES IF ANY.
3. CLEAR AND GRUB.
4. CONSTRUCT NEW STRUCTURE
5. WHEN ALL CONSTRUCTION ACTIVITY IS COMPLETE AND THE
SITE IS STABILIZED BY EITHER SEED OR SOD/LANDSCAPING, REMOVE
SILT FENCE AND RESEED ANY AREAS DISTURBED BY THE REMOVAL.
EROSION PREVENTION
THE CONTRACTOR IS RESPONSIBLE FOR PLANING FOR AND
IMPLEMENTING APPROPRIATE CONSTRUCTION PHASING,
VEGETATIVE BUFFER STRIPS, HORIZONTAL SLOPE GRADING, AND
OTHER CONSTRUCTION PRACTICES THAT MINIMIZE EROSION.
ALL EXPOSED SOIL AREAS MUST BE STABILIZED AS SOON AS
POSSIBLE TO LIMIT SOIL EROSION BUT IN NO CASE LATER THAN 14
DAYS AFTER THE CONSTRUCTION ACTIVITY IN THAT PORTION OF THE
SITE HAS TEMPORARILY OR PERMANENTLY CEASED.
THE NORMAL WETTED PERIMETER OF ANY TEMPORARY OR
PERMANENT DRAINAGE DITCH OR SWALE THAT DRAINS WATER FROM
ANY PORTION OF THE CONSTRUCTION SITE, OR DIVERTS WATER
AROUND THE SITE, MUST BE STABILIZED WITHIN 20 LINEAL FEET
FROM THE PROPERTY EDGE, OR FROM THE POINT OF DISCHARGE
INTO ANY SURFACE WATER. STABILIZATION OF THE LAST 20 LINEAL
FEET MUST BE COMPLETED WITHIN 24 HOURS AFTER CONNECTING
TO A SURFACE WATER.
STABILIZATION OF THE REMAINING PORTIONS OF ANY TEMPORARY
OR PERMANENT DITCHES OR SWALES MUST BE COMPLETE WITHIN 14
DAYS AFTER CONNECTING TO A SURFACE WATER AND
CONSTRUCTION IN THAT PORTION OF THE DITCH HAS TEMPORARILY
OR PERMANENTLY CEASED.
TEMPORARY OR PERMANENT DITCHES OR SWALES THAT ARE BEING
USED AS A SEDIMENT CONTAINMENT SYSTEM (WITH PROPERLY
DESIGNED ROCK DITCH CHECKS, BIO ROLLS, SILT DIKES ETC.) DO
NOT NEED TO BE STABILIZED. THESE AREAS MUST BE STABILIZED
WITHIN 24 HOURS AFTER NO LONGER BEING USED AS A SEDIMENT
CONTAINMENT SYSTEM.
PIPE OUTLETS MUST BE PROVIDED WITH TEMPORARY OR
PERMANENT ENERGY DISSIPATION WITHIN 24 HOURS AFTER
CONNECTION TO A SURFACE WATER.
SEDIMENT CONTROL
SEDIMENT CONTROL PRACTICES MUST MINIMIZE SEDIMENT FROM
ENTERING SURFACE WATERS, INCLUDING CURB AND GUTTER
SYSTEMS AND STORM SEWER INLETS.
SEDIMENT CONTROL PRACTICES MUST BE ESTABLISHED ON ALL
DOWN GRADIENT PERIMETERS BEFORE ANY UPGRADIENT LAND
DISTURBING ACTIVITIES BEGIN. THESE PRACTICES SHALL REMAIN IN
PLACE UNTIL FINAL STABILIZATION HAS BEEN ESTABLISHED.
ALL STORM DRAIN INLETS MUST BE PROTECTED BY APPROPRIATE
BMPS DURING CONSTRUCTION UNTIL ALL SOURCES WITH POTENTIAL
FOR DISCHARGING TO THE INLET HAVE BEEN STABILIZED.
TEMPORARY SOIL STOCKPILES MUST HAVE SILT FENCE OR OTHER
EFFECTIVE SEDIMENT CONTROLS, AND CANNOT BE PLACED IN
SURFACE WATERS, INCLUDING STORMWATER CONVEYANCES SUCH
AS CURB AND GUTTER SYSTEMS, OR CONDUITS AND DITCHES
UNLESS THERE IS A BYPASS IN PLACE FOR THE STORMWATER.
VEHICLE TRACKING OF SEDIMENT FROM THE CONSTRUCTION SITE
MUST BE MINIMIZED BY A ROCK CONSTRUCTION ENTRANCE. STREET
SWEEPING MUST BE USED IF THE ROCK ENTRANCE IS NOT
ADEQUATE TO PREVENT SEDIMENT FROM BEING TRACKED ONTO THE
STREET.
TEMPORARY DE -WATERING - DEWATERING OR BASIN DRAINING (E.G.,
PUMPED DISCHARGES, TRENCH/DITCH CUTS FOR DRAINAGE)
RELATED TO THE CONSTRUCTION ACTIVITY THAT MAY HAVE TURBID
OR SEDIMENT LADEN DISCHARGE WATER MUST BE DISCHARGED TO
A TEMPORARY OR PERMANENT SEDIMENTATION BASIN ON THE
PROJECT SITE WHENEVER POSSIBLE. IF THE WATER CANNOT BE
DISCHARGED TO A SEDIMENTATION BASIN PRIOR TO ENTERING THE
SURFACE WATER, IT MUST BE TREATED WITH THE APPROPRIATE
BMP'S SUCH THAT THE DISCHARGE DOES NOT ADVERSELY AFFECT
THE RECEIVING WATER, DOWNSTREAM LANDOWNERS OR WETLANDS.
THE CONTRACTOR MUST ENSURE THAT DISCHARGE POINTS ARE
ADEQUATELY PROTECTED FROM EROSION AND SCOUR. THE
DISCHARGE MUST BE DISPERSED OVER NATURAL ROCK RIPRAP,
SAND BAGS, PLASTIC SHEATHING OR OTHER ACCEPTED ENERGY
DISSIPATION MEASURES. ADEQUATE SEDIMENTATION CONTROL
MEASURES ARE REQUIRED FOR DISCHARGE WATER THAT CONTAINS
SUSPENDED SOLIDS.
FILTER BACKWASH WATERS MUST BE HAULED AWAY FOR DISPOSAL,
RETURNED TO THE BEGINNING OF THE TREATMENT PROCESS, OR
INCORPORATE INTO THE SITE IN A MANNER THAT DOES NOT CAUSE
EROSION. DISCHARGE OF THE BACKWASH WATER TO SANITARY
SEWER IS ALLOWED WITH PERMISSION OF THE SANITARY SEWER
AUTHORITY
SOIL COMPACTION PRECAUTIONS
THE PERMITEE MUST MINIMIZE SOIL COMPACTION AND, UNLESS
INFEASIBLE, PRESERVE TOPSOIL. MINIMIZING SOIL COMPACTION IS
NOT REQUIRED WHERE THE FUNCTION OF THE SPECIFIC AREA OF
THE SITE DICTATES THAT IT BE COMPACTED. METHODS FOR
MINIMIZING COMPACTION INCLUDE THE USE OF TRACKED
EQUIPMENT, AND STAYING OFF OF AREAS TO BE LEFT
UN -COMPACTED. METHODS TO PRESERVE TOPSOIL INCLUDE
STRIPPING AND STOCKPILING TOPSOIL PRIOR TO GRADING OR
EXCAVATION OPERATIONS.
INSPECTIONS AND MAINTENANCE
THE CONTRACTOR IS RESPONSIBLE AT ALL TIMES FOR THE
MAINTENANCE AND PROPER OPERATION OF EROSION AND SEDIMENT
CONTROL FACILITIES. THE CONTRACTOR SHALL AT A MINIMUM,
INSPECT, MAINTAIN AND REPAIR ALL DISTURBED SURFACES AND ALL
EROSION AND SEDIMENT CONTROL FACILITIES AND SOIL
STABILIZATION MEASURES.
BASED ON INSPECTION RESULTS THE CONTRACTOR MAY AND SHALL
MODIFY THE EROSION AND SEDIMENT CONTROL PLAN IN ORDER TO
PREVENT POLLUTANTS FROM LEAVING THE SITE VIA STORM WATER
RUNOFF.
POLLUTION PREVENTION
CONCRETE WASHOUT - SHALL OCCUR OFF-SITE
HAZARDOUS WASTE STORAGE AND HANDLING -OIL, GASOLINE, PAINT
AND ANY HAZARDOUS SUBSTANCES MUST BE PROPERLY STORED,
INCLUDING SECONDARY CONTAINMENT, TO PREVENT SPILLS, LEAKS
OR OTHER DISCHARGE. RESTRICTED ACCESS TO STORAGE AREAS
MUST BE PROVIDED TO PREVENT VANDALISM. STORAGE AND
DISPOSAL OF HAZARDOUS WASTE MUST BE IN COMPLIANCE WITH
MPCA REGULATIONS.
STORMWATER
FINAL GRADING OF THE LOT SHALL PROMOTE SHEET DRAINING AND
AVOID CONCENTRATION OF STORM WATER FLOWS.
FINAL GRADING SHALL MAINTAIN THE EXISTING STORM WATER
DRAINAGE PATTERNS TO THE EXTENT POSSIBLE AND PRACTICAL AS
TO NOT CAUSE ANY DAMAGE TO ADJACENT PROPERTIES.

NOTES:
SEE SURVEY, BY HARRY S. JOHNSON CO. INC., DATED 8/14/2015 FOR PROPOSED HOME ELEVATIONS &
GRADES
EXISTING DRAINAGE PATTERNS DRAINING OFF SITE SHALL NOT BE ALTERED.
DRAINAGE TO THE EAST & WEST SHALL BE DIRECTED TO THE STREET TO THE SOUTH.
PROPOSED IMPERVIOUS AREA IS GREATER THAN EXISTING, HOWEVER NEWLY CREATED IMPERVIOUS
SURFACES SHALL BE DIRECTED TOWARDS THE STREET. LESS TOTAL AREA AND LESS IMPERVIOUS
AREA WILL RUNOFF TO ADJACENT PROPERTIES IN THE PROPOSED SCENARIO.
IMPERVIOUS CALCULATIONS:
EXISTING IMPERVIOUS SURFACE = 2,539 SF
PROPOSED IMPERVIOUS SURFACE = 2,831 SF
