Show date of plan or revision, North Arrow, drawing scale, property address or Sid well
number and property legal description.
Label floodplains and wetlands when present.
Indicate all existing or proposed water courses, swales or ditches.
Provide information on all variances or special conditions approved by the Township.
Provide 0.5 feet of fall within first 25 feet from building finish grade to side, front or rear
yard highpoints.
Provide proposed spot grades on an approximate 50-foot grid pattern throughout site and
to 100 feet onto adjacent sites. Proposed grade contours can be provided to supplement
the spot grades.
Provide proposed grades for first floor, garage and basement if included.
Provide existing grades at property corners, along property line, along top of curb, along
top and bottom of any retaining walls along with all high points and low points.
Provide site benchmark on USGS datum.
Provide finish grade of adjacent houses. If adjacent lot is vacant, state so on the plan.
Proposed grades along property line must match approved master grading plan.
Provide setbacks as appropriate from property line.
All overland drainage routes must be maintained. Lowest house grades are to be a
minimum of 1-foot above the highest overland flow route elevation.
Driveways shall have slopes indicated which are less than 10-percent. Preferred slopes
are 2 to 8-percent.
Driveway locations are to match the approved plans.
Slope from building to side yard cannot exceed 1:3 slopes. Stability computations must
be provided for any grade change over 2 feet that is steeper than one vertical to two
horizontal, example; a retaining wall.
Minimum land and swale slopes to be 1-percent.
Ensure architectural plan elevations and footprint match plot plan.
Sanitary sewer lead location is to be shown at the as-built location with invert elevation.
Provide proposed grade of the sanitary lead.
Provide sump lead location. Sump lead must have a minimum 2-foot of cover at the
building and 3-foot of cover everywhere else. The sump lead must connect above all
trunk line pipes at structures.
Show all catch basins, manholes and inlets with as-built rim and invert elevations.
Show and label all easements.
Show 5-foot wide concrete sidewalk along right-of-way with proposed grading as
appropriate for development.
Also see example As-Built plot plan for additional information.
