Page 3
Additional grading required to meet the 20% slope road and driveway
standard shall not count against the maximum graded area permitted by
the General Plan. To achieve a grading allowance, the applicant will be
required to prepare two concept grading plans, one denoting the 25% or
less driveway and the other a 20% or less driveway slope. The difference
in the amount of graded area between the two concept grading plans
would not be counted toward the maximum graded area. If the quantity of
material graded to achieve the 20% slope exceeds the maximum
allowable graded area for the lot by less than 20%, the Director of
Development Services may approve the additional grading. If the quantity
of material graded to achieve the 20% slope exceeds the maximum
allowable graded area for the lot by 20% or more, approval by the City
Council is required. In either case, the quantity of material that may
exceed the maximum graded area is limited to only the quantity of material
necessary to reduce the road or driveway slope from a maximum of 25%
to 20%.
Section 3: The following Section 15.24.170 of Title 15 of the Poway Municipal Code
Fire apparatus access roads - Specifications are amended to read as follows:
S 902.2.2.6 Grade. The gradient for a fire apparatus access roadway shall not exceed
20.0%. Grades exceeding 15.0% (incline or decline) shall not be permitted without
mitigation. Minimal mitigation shall be the installation of fire sprinkler systems
appropriate to the structures and uses served. The Chief may require additional
mitigation measures where he deems appropriate. The angle of departure and angle of
approach of a fire access roadway shall not exceed the maximum approved by the
Chief.
Section 4: This Ordinance shall be codified.
