The Maple Ridge Watercourse Protection Bylaw 6410-2006 and Subdivision Control Bylaw 4800-1993
require the Developer of a subdivision to meet the design grades as proposed on the Comprehensive
Lot Grading Plan submitted as part of the design of the subdivision servicing works. This Bulletin is
meant to detail how that requirement must be met prior to either; the application for Building Permits
or the issuance of a Certificate of Completion for the subdivision servicing.
The City of Maple Ridge will require a written statement from a BC Land Surveyor (BCLS) stating that
the grades on the subdivision are accurately constructed to within 150mm (6 inches) of the
Professional Engineer of Record's Comprehensive Lot Grading Plan design. This includes all
designated control points such as but not limited to:
• Lot corner grades,
• Developer lawn basin rim elevations, and
• “Top and Bottom” elevations of Developer Retaining Walls.
Further, this letter must confirm that the Developer Retaining Walls’ location (in relation to property
lines) meets the approved design per Subdivision Control Bylaw 4800-1993, Schedule C, Page 43,
Section 3.3.2.11.(excerpt attached).
Retaining walls that are the Developer's responsibility are to be installed as part of the subdivision
servicing process. Changes in grades due to sloping sites are to be achieved through terracing of the
properties where future retaining walls along property lines are the responsibility of individual Builders.
The City will not issue a Certificate of Completion for the subdivision servicing nor will it accept any
building permit applications until the BCLS verification letter has been supplied in a form satisfactory
to the Building Department. (Sample letter to be provided)
It will be the Developer’s responsibility to provide the subject letter with the As-Built Lot Grading Plan to
Builders, when they are selling the property. All Builders must request this surveyor confirmation letter
with the As-Built Lot Grading Plan from Developers as Building Permit applications will not be accepted
without the above required documentation.
Allowances can be made if the Developer is the Builder for all the lots but this must be discussed and
identified prior to the application for any Building Permits or the issuance of a Certificate of
Completion. The Building Department may rely on sign off from a Registered Professional (Civil
Engineer of Record) and accept the As-Built Lot Grading Plan issued (signed/sealed) by the Engineer of
Record as a confirmation, when Developer and Builder are the same.
The enforcement of this bulletin will take effect February 15, 2015 for all subdivision applications that
have not received their Preliminary Review Letter (PRL) or their PRL is dated after February 14, 2015.
Exceptions to this would be subdivision applications that have already had this requirement identified

EROSION AND SEDIMENT CONTROL PLANEROSION AND SEDIMENT CONTROL PLANEROSION AND SEDIMENT CONTROL PLANEROSION AND SEDIMENT CONTROL PLAN
11. Where Construction Works consist of Subdivision and Surveying Works, the final grading of a
site must meet the specifications of the grading design requirements set out in either the
grading plan or comprehensive grading plan in accordance with the subdivision and servicing
agreement. The developer named in a subdivision agreement is responsible for providing the
following information, at the developer’s cost, before the Building or Engineering Department
consider authorizing a lot for building permit issuance or issuance of a Certificate of
Subdivision Completion, whichever is the earlier of the two:
a. provide a comprehensive grading design to the Engineering Department that has been
reviewed, signed, and sealed by a qualified Professional Engineer;
b. a tentative schedule for implementation of the grading construction works in accordance
with the comprehensive grading plan and ESC plan;
c. written verification from a BC Land Surveyor that the Professional Engineer of record’s
approved grading plan is accurately constructed to within six (6) inches from the approved
comprehensive grading plan and/or the approved regular grading plan.”
Excerpt from Maple Ridge Subdivision Control Bylaw 4800-1993
Section 3.3.2.11Section 3.3.2.11Section 3.3.2.11Section 3.3.2.11 Lot GradingLot GradingLot GradingLot Grading
Lots shall be graded in compliance with the lot grading plan. The designated
control points on the plan (corner pins, grade changes, lawn basins, swale
line and grade) shall be constructed to design elevations. The ground
between control points shall be uniformly graded to a tolerance of plus or
minus 150mm.
NOTE: The Developer is advised that lot grading is considered an “essential
service” and is required prior to the issuance of building permits. To
facilitate Building Permit issuance and to provide the builders with
accurate site information, the submission and acceptance of the lot
grading record drawing(s) is required prior to issuance of the building
permit.
