Ohl, Deputy City Attorney, ext. 3131, dohl @city.newport - beach.ca.us SUBJECT: Modification of Newport Beach Municipal Code Section 14.24.020 Dwelling Unit and Business Structure Sewer Connection ISSUE: • Should the municipal code be amended to include provisions to require the installation of sewer lateral clean -outs and replacement of existing sewer lateral piping when one or more specified criteria are met? RECOMMENDATION: Introduce Ordinance No. 2005- and pass to second reading. DISCUSSION: Staff is routinely called with complaints of sewer back ups and clogged lines. In most instances it is reported that the City's main line has caused the problem. The City cleans and maintains the portion of the sewer lateral from the private property boundary to the main sewer line in the street. Due to routine maintenance of City lines, the sewer main is -seldom, if ever, the cause of back ups. This is confirmed by inspecting the main line. It is usually necessary to enter the sewer lateral line to locate the blockage. The preferred point of entry is a clean -out located at the property line. Otherwise residents expect staff to enter their property and find the blockage, which in most instances is on the private property side of the property line. • In response to this situation, the Utilities Department, in conjunction with the Building Department has, since 1988, (See Attachment A, the most recent memo) required the installation of sewer lateral clean -outs at the property line and the replacement of Modification to Newport Beach Municipal Code Section 14.24.020 November 22, 2005 Page 2 existing sewer lateral piping to bring both to current standards when substantial construction work is done on the property. (See Attachment B) These requirements are triggered wheh one or more of six criteria exist. There are two major.benefits with these requirements. First, if there is a stoppage in the line past the property line on the City maintained portion, the clean -out protects the property owner and the City by allowing the back up to escape outside, as opposed to inside, the residence. This significantly reduces property damage. Secondly, the clean out allows staff to save time and money by entering the City maintained portion of the lateral and determining if the blockage is the City's responsibility to correct, or if it is on the private property side of the line. Staff recommends that the criteria be specifically incorporated into the Municipal Code to clarify the requirements. Environmental Review: DNA This is not a project under CEQA.
