CITY POLICY
Landform Conservation
Areas -
Oak Ridges Moraine
(cont’d)
Landform Conservation Areas
on the Oak Ridges Moraine
are areas consisting of steep
slopes and represent
landforms that shall be
protected for their
contribution to the ecological
integrity and hydrological
function of the Moraine.
For the purpose of section
15.40, “major development”
means development
consisting of the creation of
four or more lots, the
construction of a building or
buildings with a ground floor
area of 500 sq. m. or more, and
the establishment of a major
recreational use.
(b) limit the portion of the net developable
area of the site that is disturbed to not
more than 25 per cent of the total area of
the site, and limit the net developable area
of the site that has impervious surfaces to
not more than 15 per cent of the total area
of site for areas shown as Category 1 Areas
with the exception of mineral aggregate
operations (see Schedule VII);
(c) limit the portion of the net developable
area of the site that is disturbed to not
more than 50 per cent of the total area of
the site, and limit the net developable area
of the site that has impervious surfaces to
not more than 20 per dent of the total area
of the site for areas shown as Category 2
Areas with the exception of mineral
aggregate operations (see Schedule VII);
(d) require proponents of an application for
major development with respect to land in
a landform conservation area (Categories 1
and 2) to include a landform conservation
plan that,
(i) identifies elevation contours in
sufficient detail to show the basic
topographic character of the site,
with an interval of not more than two
metres;
(ii) analysis of the site by slope type;
(iii) identifies significant landform
features such as kames, kettles,
ravines and ridges; and
(iv) identifies all water bodies including
intermittent streams and ponds;
(e) require that the landform conservation
plan shall also include a development
strategy that identifies appropriate
planning, design and construction
practices to minimize disruption to
landform character, including:
(i) retention of significant landform
features in an open, undisturbed form;
(ii) road alignment and building
placement to minimize grading
requirements;
(iii) concentration of development on
portions of the site that are not
significant;
