The purpose of the provisions codified in this chapter is prohibition against obstructing watercourses or degrading water quality of waters flowing through watercourses not within rights-of-way under Alameda County Flood Control and Water Conservation District and City of Livermore ownership.
(1960 code § 25.1; Ord. 2065 § 1(A), 2018)
The City Council does find and declare as follows:
A. 
That, in consonance with the finding of the State Legislature that the state has a primary interest in preserving and maintaining watercourses to provide beneficial use of waters to the people of the state, the people of the City of Livermore have a primary interest in the conservation, control and utilization of the water resources contained in the City, and that the quality of all waters of the City shall be protected for use and enjoyment of the residents thereof; that the activities and factors which may affect the quality of the waters of the City and the assured free flow of such waters be regulated to attain the highest water quality which is reasonable, considering all demands being made and to be made on those waters; and further, that the health, safety and welfare of the people of the City require that there be, in addition to the statewide program for the control of quality of all waters in the state, a local program consistent with and in furtherance of said state program to insure the removal of all authorized obstructions, impediments and unlawful deviations of the free flow of water through the watercourses of the City;
B. 
That the City and the Alameda County Flood Control and Water Conservation District, hereinafter referred to as "ACFCWCD," own respectively certain watercourses or portions thereof within the City which, because of said ownership, are adequately protected and maintained;
C. 
That obstruction or degradation of water quality of watercourses not under the ownership of the ACFCWCD and the City within the City adversely affects the integrated program of flood control and water conservation pursued since the inception of ACFCWCD as well as the health, safety and welfare of the inhabitants of the City who suffer detriment by virtue of said obstruction or degradation of water quality;
D. 
That investigation and study of watercourses not under the ownership of ACFCWCD or the City disclose an increasing incidence of obstruction and degradation of water quality by the depositing of foreign material within said watercourses, with resulting injury to property owners both riparian and nonriparian;
E. 
That unobstructed flow of high-quality water is necessary to maximize the beneficial use of water by the inhabitants of the City.
(1960 code § 25.2; Ord. 2065 § 1(A), 2018)
It is declared to be in the interest of the public health, safety and welfare that:
A. 
Watercourses located within the City and not under ownership of ACFCWCD or the City be maintained free of obstructions and materials which contribute to the degradation of water quality;
B. 
The owners of property through which said watercourses flow are primarily responsible for maintaining a free flow of water through said property and to maintain the quality of water as such water passes to downstream users;
C. 
The City shall assume responsibility for abatement of watercourse obstruction or water quality degradation in the absence of exercise by owners of such primary responsibility, through commencement and prosecution of abatement proceedings before the City Council.
