Landform conservation areas
 30. (1) The following, shown on maps entitled “Landform Conservation Areas of the Oak Ridges Moraine”, numbered 1, 2, 3 and 4, dated March, 2002 and on file in the offices of the Ministry of Municipal Affairs at Toronto, are landform conservation areas: 1.  Landform conservation areas (Category 1). 2.  Landform conservation areas (Category 2).  O. Reg. 140/02, s. 30 (1); O. Reg. 141/17, s. 22 (1). (2) Copies of the map referred to in subsection (1) are available on a website maintained by the Government of Ontario. O. Reg. 141/17, s. 22 (2). (3) When official plans and zoning by-laws are amended in accordance with sections 9 and 10 of the Act to bring them into conformity with this Plan, the boundaries of the landform conservation areas may be further defined, in a manner that is consistent with the maps referred to in subsection (1), but with greater precision than the maps can show.  O. Reg. 140/02, s. 30 (3). (4) The further definition of boundaries described in subsection (3) does not require an amendment to this Plan.  O. Reg. 140/02, s. 30 (4). (5) An application for development or site alteration with respect to land in a landform conservation area (Category 1) shall identify planning, design and construction practices that will keep disturbance to landform character to a minimum, including, (a)  maintaining significant landform features such as steep slopes, kames, kettles, ravines and ridges in their natural undisturbed form; (b)  limiting 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 (c)  limiting the portion of the net developable area of the site that has impervious surfaces to not more than 15 per cent of the total area of the site.  O. Reg. 140/02, s. 30 (5). (6) An application for development or site alteration with respect to land in a landform conservation area (Category 2) shall identify planning, design and construction practices that will keep disturbance to landform character to a minimum, including, (a)  maintaining significant landform features such as steep slopes, kames, kettles, ravines and ridges in their natural undisturbed form; (b)  limiting 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 (c)  limiting the portion of the net developable area of the site that has impervious surfaces to not more than 20 per cent of the total area of the site.  O. Reg. 140/02, s. 30 (6). (7) Subsections (5) and (6) do not apply in respect of mineral aggregate operations.  O. Reg. 140/02, s. 30 (7). (8) An application for major development with respect to land in a landform conservation area of either category shall be accompanied by a landform conservation plan that shows, on one or more maps, (a)  elevation contours in sufficient detail to show the basic topographic character of the site, with an interval of not more than two metres; (b)  analysis of the site by slope type (for example, moderate or steep); (c)  significant landform features such as kames, kettles, ravines and ridges; and (d)  all water bodies including intermittent streams and ponds.  O. Reg. 140/02, s. 30 (8). (9) 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, (a)  retention of significant landform features in an open, undisturbed form; (b)  road alignment and building placement to minimize grading requirements; (c)  concentration of development on portions of the site that are not significant; (d)  use of innovative building design to minimize grading requirements; and (e)  use of selective grading techniques.  O. Reg. 140/02, s. 30 (9). (10) An application for development or site alteration that does not constitute major development, with respect to land in a landform conservation area of either category, shall be accompanied by a site plan that, (a)  identifies the areas within which all building, grading and related construction will occur; (b)  demonstrates that buildings and structures will be located within the areas referred to in clause (a) so as to minimize the amount of site alteration required; and (c)  provides for the protection of areas of natural and scientific interest (earth science) in accordance with subsection (12).  O. Reg. 140/02, s. 30 (10). (11) Subsection (10) does not apply in respect of mineral aggregate operations.  O. Reg. 140/02, s. 30 (11). (12) An application for development or site alteration with respect to land in an area of natural and scientific interest (earth science) or the related minimum area of influence shall be accompanied by an earth science heritage evaluation that, (a)  identifies planning, design and construction practices that will ensure protection of the geological or geomorphological attributes for which the area of natural and scientific interest was identified; and (b)  determines whether a minimum vegetation protection zone is required, and if so, specifies the dimensions of that zone and provides for the maintenance and, where possible, improvement or restoration of natural self-sustaining vegetation within it.  O. Reg. 140/02, s. 30 (12). (13) With respect to land in Settlement Areas, in considering applications for development or site alteration within landform conservation areas (Category 1 and 2), the approval authority shall consider the importance of adopting planning, design and construction practices that will keep disturbance to landform character to a minimum, so as to satisfy the requirements of subsections (5) to (11) if possible.  O. Reg. 140/02, s. 30 (13).
