This chapter shall be known as the "City of Menlo Park Storm Water Management Program" and may be so cited. (Ord. 859 (part), 1994).

7.42.020 Purpose and intent.

The purpose of this chapter is to ensure the future health, safety, and general welfare of city citizens by:

(a)    Eliminating non-storm water discharges to the municipal separate storm sewer;

(b)    Controlling the discharge to municipal separate storm sewers from spills, dumping or disposal of materials other than storm water;

(c)    Reducing pollutants in storm water discharges to the maximum extent practicable.

The intent of this chapter is to protect and enhance the water quality of our watercourses, water bodies, and wetlands in a manner pursuant to and consistent with the Clean Water Act. (Ord. 859 (part), 1994).

7.42.030 Definitions.

(a)    Any terms defined in the Federal Clean Water Act and acts amendatory thereof or supplementary thereto, and/or defined in the regulations for the storm water discharge permitting program issued by the Environmental Protection Agency on November 16, 1990 (as may from time to time be amended) as used in this chapter shall have the same meaning as in that statute or regulations. Specifically, the definition of the following terms included in that statute or regulations are hereby incorporated by reference, as now applicable or as may hereafter be amended: discharge, illicit discharge, pollutant, and storm water. These terms presently are defined as follows:

(1)    Discharge. (A) Any addition of any pollutant to navigable waters from any point source, or (B) any addition of any pollutant to the waters of the contiguous zone or the ocean from any point source other than a vessel or other floating craft.

(2)    Illicit Discharge. Any discharge to the city storm sewer system that is not composed entirely of storm water except discharges pursuant to a NPDES permit and discharges resulting from fire fighting and other emergency response activities.

(3)    Pollutant. Dredged soil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials, wrecked or destroyed equipment, rock, sand, cellar dirt and industrial, municipal, and agricultural waste discharge into water. A pollutant shall also include any increment or increase in the total volume of storm water runoff resulting from any activity or development occurring after the effective date of the ordinance codified in this chapter.

(4)    Storm Water. Storm water runoff and surface runoff and drainage.

(b)    When used in this chapter, the following words shall have the meanings ascribed to them in this section:

(1)    Authorized Enforcement Official. The city manager or his/her designees is hereby authorized to enforce the provisions of this chapter.

(2)    Best Management Practices (BMPs). Schedules of activities, prohibitions of practices, general good housekeeping practices, pollution prevention practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants directly or indirectly to "waters of the United States." BMPs also include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.

(3)    City. The city of Menlo Park.

(4)    City Storm Sewer System. Includes but is not limited to those facilities within the city by which storm water may be conveyed to waters of the United States, including any roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels or storm drains, which is not part of a publicly-owned treatment works (POTW) as defined at 40 CFR 122.2.

(5)    Non-storm Water Discharge. Any discharge that is not entirely composed of storm water except those noted within an NPDES permit and this chapter.

(6)    Premises. Any building, lot parcel, real estate, or land or portion of land, whether improved or unimproved, including adjacent sidewalks and parking strips.

(7)    Watercourse. A natural stream, creek, or man-made uncovered channel through which water flows continuously or intermittently. (Ord. 859 (part), 1994).

7.42.040 Responsibility for administration.

This chapter shall be administered for the city by the city manager and his/her designees. (Ord. 859 (part), 1994).

7.42.050 Construction and application.

This chapter shall be construed to assure consistency with the requirements of the Federal Clean Water Act and acts amendatory thereof or supplementary thereto, applicable implementing regulations, and NPDES Permit No. CA0029921 and any amendment, revision or reissuance thereof. (Ord. 859 (part), 1994).

7.42.060 Severability and validity.

If any portion of this chapter is declared invalid, the remaining portions of this chapter are to be considered valid. (Ord. 859 (part), 1994).

7.42.070 Waiver procedures.

(a)    It is the intent of this chapter to protect and enhance water quality while respecting the rights of private property owners to an economically viable use of land. It is not the intent of this chapter to prohibit all economically viable use of any private lands, nor to result in a confiscatory impact. Accordingly, the purpose of this section is to provide for an administrative procedure for a waiver or modification of a particular provision of this chapter in the event the strict application of this chapter would result in the denial of all economically viable use of real property.

(b)    An applicant for a waiver of a provision of this chapter shall file a waiver applicant with the director of the engineering division on a form provided by the director identifying the provision sought to be waived or modified. The applicant shall file a complete form and shall provide all documentation and information required by the director to determine whether application of the provision in question will prohibit any economically viable use of the land in question or otherwise have an impermissible confiscatory result.

(c)    The director may approve, deny or conditionally approve a waiver application upon making all of the following written findings:

(1)    That the strict application of the provision for which a waiver or modification is sought would result in the denial of all economically viable use of the real property in question;

(2)    To the maximum extent feasible, conditions have been placed upon such a waiver or modification in order to achieve the goals of this chapter as closely as possible while still allowing economically viable use of the real property in question;

(3)    Approval of such a waiver will not result in a public nuisance which would constitute a significant and direct threat to public health or safety. (Ord. 859 (part), 1994).

7.42.080 Discharge of pollutants.

(a)    Prohibition. The discharge of non-storm water discharges to the city storm sewer system and watercourses is prohibited. The discharge of rubbish, refuse, bark, sawdust, or other solid wastes into surface waters or at any place where they would contact or where they would be eventually transported to surface waters including floodplain areas is prohibited.

(b)    Implementation of NPDES Permit Conditions. The public works director, community development director or designees shall have authority to adopt policies to implement NPDES Permit No. CAS612008 and all subsequent permits or amendments. These policies may include best management practices (BMPs) to control and reduce non-storm water and polluted storm water discharges to storm drains and watercourses; including but not limited to conditions of approval, maintenance agreements, regular inspections and reporting requirements.

(c)    Permitted Discharges. All discharges of material other than storm water must be in compliance with a NPDES permit issued for the discharge (other than NPDES Permit No. CAS612008) and this chapter. (Ord. 1055 § 2, 2019: Ord. 859 (part), 1994).

7.42.090 Exceptions to discharge prohibition.
