6.2 Avoid extensive grading when creating parks,
trails and open spaces.
6.3 Preserve contiguous open space networks to
provide habitat linkages within the site and
to neighbouring areas. Where practical these
networks should be integrated into existing
riparian corridors.
6.4 Utilize trails to connect parks and schools as
well as parts of the community that cannot be
linked by roads due to topographic constraints.
6.5 Locate key park spaces to capitalize on scenic
views from the hillside.
6.6 Set up barriers with clear warning signage to
discourage the public from accessing slopes
that are considered dangerous.
7. Roads:
7.1 Align roads to follow natural site contours,
conforming to topographic conditions rather
than cutting across contours.
7.2 Provide for reduced design speeds (minimum
40 km/hour on collectors and arterials and
minimum 30 km/hour on local roads) and
increased road grades (maximum 15%) where
it can be demonstrated that design measures
will be employed to help ensure that travelled
speeds remain close to the posted speed limits
through reduced straight sight distances and
road geometric design.
7.3 Utilize connectivity in the road network over
long cul-de-sacs and “dead-end” situations
where topographic conditions permit.
7.4 Utilize alternative approaches to turnarounds
(e.g. hammerhead configurations) to reduce
the amount of required grading works.
7.5 Allow cul-de-sac length to be increased where
connectivity in the roadnetwork is not possible
due to topographic conditions, provided that
appropriate emergency access is constructed.
Emergency vehicle access lanes shall generally
have a minimum hard packed surface width of
4 metres and a cleared width of 6 metres.
7.6 Utilize split roads and/or one-way roads
to preserve significant natural features, to
reduce the amount of slope disturbance, or
to improve accessibility to individual parcels.
7.7 Require one-way roads to have a minimum
pavement width of 6 metres and a minimum
right-of-way of 10 metres.
7.8 Utilize reduced pavement widths and right-
of-way widths (e.g. local road with minimum
pavement width of 6 metres plus parking
bays and minimum right-of-way of 12 metres)
where service levels and emergency access
can be maintained. The reduced widths
should demonstrate less slope disturbance,
and the reduced widths should contribute to
the overall neighbourhood character.
7.9 Encouraging meandering sidewalks adjacent
to the road as a means of eliminating long,
sustained steeper grades, preserving natural
features, or reducing grading requirements
within the right-of-way. Varied offsets
between the road and sidewalk will be
considered for these purposes.
8. Driveways and Lanes:
8.1 Individual driveway grades up to 20% may
be permitted where site conditions warrant
and where it can be demonstrated that grade
transitions will ensure good vehicular access.
8.2 Ensure the first 3.5mon a downslope driveway
has a grade no greater than 7%.
8.3 Lanes and shared driveways may be permitted
where significant site grading can be reduced
with the following provisions:
a. Grades should not exceed 14%.
b. Single in and out lanes, and shared
driveways should be limited to
servicing 6 lots and they should
include turn around provisions.
c. Through lanes and shared driveways
may service up to 15 lots.
