AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF RANCHO
CUCAMONGA, CALIFORNIA, ESTABLISHING A SPECIAL DRAINAGE
IMPACT ZONE NORTH OF THE SANTA FE RAILROAD TO ARROW ROUTE
BETWEEN HAVEN AND MILLIKEN AVENUES, AND REQUIRING DETAILED
ENGINEERING STUDIES AND MITIGATION MEASURES IN CONNECTION
THEREWITH.
The City Council of the City of Rancho Cucamonga, California,
does ordain as follows:
SECTION 1: Statement of Intent and Purpose
In recognition of the existence of unique drainage
problem creating potential hazards to public health, safety, and property,
the City Council deems it appropriate to establish that portion of the
City bounded by:
"The Santa Fe Railroad on the south, Arrow Route on the north,
Haven Avenue on the west, and the alignment of Milliken Avenue on
the east"
as a Special Drainage Impact Zone requiring special engineering studies
and mitigations measures as a condition of the issuance of a building
permit.
SECTION 2: Drainage Study Requirements
The City Council finds that prior to the issuance of
a Building permit within the Special Impact Zone boundary described in
Section 1, the applicant is hereby required to submit for approval of
the City Engineer a comprehensive hydrology study prepared by a Registered
Civil Engineer in the State of California. This study shall contain the
following:
1. Analysis of existing drainage patterns and runoff quantities
on the site.
2. The existing ultimate discharge point of site runoff and the
general downstream path of runoff.
3. The proposed drainage patterns and increases in runoff quantities
generated by site development.
4. Proposed mitigation measures to prevent the discharge of
increased storm runoff from the site including proposed
construction of master plan facilities sufficient to mitigate
downstream damage.
5. Any other information required by the City Engineer to determine
the full drainage impacts of the proposed development.
SECTION 3: Findings Required for Building Permit Issuance
No building permit shall be issued for a structure
within the Special Impace Zone unless the City Engineer has made the
following findings:
1. That the proposed project will not increase storm runoff from
the site except where acceptable drainage facilities exist to
accept said runoff.
2. That the project by reasons of low-flow non-storm related
water will not create a public nuisance.
3. That the project will not divert or concentrate flows in such
a manner as to adversely effect downstream properties. To
insure this finding, the City Engineer may require a drainage
acceptance letter or easement from the adjacent downstream
property.
4. That where on-site retention facilities have been proposed a
sufficient maintenance contract has been executed and security
posted to insure proper maintenance of said facility. Minimum
security for maintenance shall be $2,000 or such other higher
amount as set by the City Council upon recommendation of the
City Engineer.
5. That all facilities proposed are in conformance with City
standards for design and construction.
These findings will be made subject to conditions established
by the City Engineer based upon the findings of the approved
Drainage Study.
SECTION 4: Security for Construction of Required drainage
improvements
Where the findings required by Section 3 are based
on conditions requiring the construction of drainage improvements, no
building permit shall be issued until an agreement and bonds, letters of
credit, cash deposit, or other acceptable form of security have been
posted and accepted by the City Council to insure the construction of
required facilities.
SECTION 5: Drainage Fee Provisions
(a) Where a building permit is sought for in addition
to existing development within the Special Drainage Zone, the building
permit shall not be issued until drainage fees under the provisions of
City Ordinances have been paid for the entire developed area of the
site. The developed area shall be as defined in Section 4(c)(2) of
Ordinance 75 and shall be determined by the Building Official.
(b) Within the Special Drainage Impact Zone, the
provision of Section 4(c)(3) of Ordinance No. 75 shall not apply.
SECTION 6: The Mayor shall sign this Ordinance and the City
Clerk shall cause the same to be published within fifteen (15) days
after its passage at least once in The Daily Report, a newspaper of
general circulation published in the City of Ontario, California, and
circulated in the City of Rancho Cucamonga, California.
PASSED, APPROVED, and ADOPTED this day 16th day of July, 1980.
