Ordinance No. 552
Page 7
4. City Review and Plan ADDroval
a) Prior to the issuance of a building permit for a New Development
or Redevelopment Project, the City may evaluate the proposed project using the
applicable SUSMP and the guidelines and BMP list approved by the Regional
Board, and erosion and grading requirements of the City Building Official or
Director to determine (i) its potential to generate the flow of Pollutants into the
Municipal Storm Drain System both during and after construction, and (ii) how
well the Urban Runoff Mitigation Plan for the proposed project meets the goals of
this chapter. Each plan will be evaluated on its own merits according to the
particular characteristics of the project and the site to be developed. Based upon
the review, the City may impose conditions upon the issuance of the building
permit, in addition to any required by the State Construction Activities Storm
Water Permit for the project, in order to minimize the flow of Pollutants into the
Municipal Storm Drain System.
b) No grading permit for developments with a disturbed area of five
acres or greater shall be issued unless the applicant can show that a Notice of
Intent to comply with the State Construction Activities Storm Waste Permit has
been filed and that a Storm Water Pollution Prevention Plan has been prepared for
the project.
C) The Director may approve or disapprove of the Urban Runoff
Mitigation Plan within thirty (30) calendar days of submittal, or within thirty (30)
days of approval of the development project by the Planning Commission, where
Planning Commission approval is required. If the plan is disapproved, the reasons
for disapproval shall be given in writing to the applicant. Any plan disapproved
may be revised by the applicant and resubmitted for approval. A resubmitted plan
will be approved or disapproved within thirty (30) days of submittal. No building
permit shall be issued until an Urban Runoff Mitigation Plan has been approved
by the Director.
d) If no building permit has been issued or no construction has begun
on a project within a period of one hundred and eighty (180) days of approval of
an Urban Runoff Mitigation Plan, the Urban Runoff Mitigation Plan for that
project shall expire. The Director may extend the time by written extension for
action by the applicant for a period not to exceed one hundred and eighty (180)
days upon written request by the applicant showing that circumstances beyond the
control of the applicant prevented the construction from commencing. In order to
renew the Urban Runoff Mitigation Plan, the applicant shall resubmit all
necessary forms and other data and pay a new plan review fee.
e) Storm Water Runoff containing sediment, construction waste or
other Pollutants from the construction site and parking areas shall be reduced to
the maximum extent practicable. The following Best Management Practices shall
apply to all construction projects within the City, and shall be required from the
Ordinance No. 552
Page 8
time of demolition of existing structures or commencement of construction until
receipt of a certificate of occupancy:
f 1) Sediment, construction waste, and other Pollutants from
construction activities shall be retained on the construction site to the
maximum extent practicable.
r'
2) Structural controls such as sediment barriers, plastic
sheeting, detention ponds, dikes, filter beams and similar controls shall be
utilized to the maximum extent practicable in order to minimize the escape
of sediment and other Pollutants from the site.
3) All excavated soil shall be located on the site in a manner
that minimizes the amount of sediments running onto the street, drainage
facilities or adjacent properties. Soil piles shall be covered with plastic or
similar material until the soil is either used or removed from the site.
4) No washing of construction or other vehicles is permitted
adjacent to a construction site. No water from the washing of construction
or other vehicles is permitted to run off the construction site, or to
otherwise enter the Municipal Storm Drain System.
f) As a condition to granting a construction permit, the City may set
reasonable limits on the clearing of natural vegetation from construction sites, in
order to reduce the potential for soil erosion. These limits may include, but are
not limited to, regulating the length of time soil is allowed to remain bare or
prohibiting bare soil.
g) The Director may require, prior to the issuance of any building or
grading permit, preparation of appropriate wet weather erosion control, storm
water pollution prevention or other plans consistent with Countywide
Development Construction Guidance provisions and the goals of this chapter.
h) Full or partial waivers of compliance with the requirements of this
section may be obtained by Persons who apply in writing and show that
incorporation of design elements that address the objectives set forth above is an
economic or physical impossibility due to the particular configuration of the site
or due to irreconcilable conflicts with other City requirements. All such requests
for waivers must be approved, in writing, by the Director of Planning, the
Director of Public Works Department, and the Director of Building.
Section 3. Severability. If any section, subsection, subdivision, paragraph, sentence,
clause or phrase in this Ordinance, or any part thereof, is held invalid or unconstitutional, such
decision shall not affect the validity of the remaining sections or portions of this chapter or part
thereof. The City Council hereby declares that it would have passed each section, subsection,
subdivision, paragraph, sentence, clause or phrase of this Ordinance irrespective of the fact that
Ordinance No. 552
Page 9
any one or more sections, subsections, subdivisions, paragraphs, sentences, clauses or phrases
may be declared invalid or unconstitutional.
