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.
