AUTHORIZED ENFORCEMENT AGENT: The Director of the Boise City Department of Planning and Development Services and/or any individual designated by the Director of the Boise City Department of Planning and Development Services as an authorized enforcement agent. The authorized enforcement agent must complete initial training regarding proper control measure selection, installation and maintenance as well as administrative requirements such as inspection reporting and tracking and the implementation of enforcement actions. The authorized enforcement agent must also complete annual refresher training to receive updates on preferred BMPs, regulation changes, permit updates and policy or standards updates.
BEST MANAGEMENT PRACTICES (BMPs): Physical, structural and/or managerial practices that, when used alone or in combination, control activities, including, but not limited to, site runoff, spillage and leaks, and waste disposal, and prevent or reduce the discharge of pollutants directly or indirectly to waters of the State or U.S. BMPs may include schedules of activities, prohibition of practices, design standards, educational activities and treatment requirements.
CLEAN WATER ACT (CWA): Federal Water Pollution Control Act enacted by Pub.L 92-500, as amended by Pub.L 95-217, 95-576, 96-483 and 97-117, enacted at 33 USC 1251 et seq.
CONSTRUCTION ACTIVITY: Activities occurring in furtherance of a construction project, including, but not limited to, land disturbing activities; temporary crushing and screening operations lasting less than one hundred eighty (180) calendar days, and hauling of soil and rock; explosive and abrasive blasting; implosion; handling of building materials; concrete, stone and tile cutting; operation of motorized and nonmotorized machinery; and operation of motor vehicles on the site, staging areas, parking areas, storage areas, or any access routes to the construction site.
DIRECTOR: The Director of the Boise City Department of Planning and Development Services.
ENVIRONMENTALLY SENSITIVE AREA (ES): Projects located within fifty feet (50') of the Boise River, irrigation canals, or any other redefined tributary or conveyance (freeflowing or intermittent) or wetland from the area of disturbance and/or projects located on slopes fifteen percent (15%) or greater.
EROSION: Progressive detachment and removal of particles, including soil and rock fragments, from the earth's surface by means of water, wind, ice, gravity or mechanical processes, including vehicular traffic.
EROSION CONTROL PLAN (ECP): Details of the concepts and techniques, including BMPs, used prior to and during construction, up to and including final landscaping, to control and limit soil erosion, mud and dirt deposits on public roadways, and sediment discharge.
FINAL STABILIZATION: A. All soil disturbing activities at the site have been completed and one of the three (3) following criteria are met:
1. A uniform (e.g., evenly distributed, without large bare areas) perennial vegetative cover with a density of seventy percent (70%) of the vegetative cover existing prior to earth disturbing activities for the area has been established on all unpaved areas and areas not covered by permanent structures 1 . For all areas designated as hillside or foothill area, the minimum acceptable plant coverage shall meet the stabilization requirements set forth in the hillside and foothill areas development ordinance, title 11, chapter 11-07 of this Code.
2. Equivalent permanent stabilization measures (such as the use of riprap, gabions or geotextiles) have been employed to provide effective cover.
3. Temporary erosion control measures (e.g., degradable rolled erosion control product) are selected, designed and installed along with an appropriate seed base to provide erosion control for at least three (3) years without active maintenance. The temporary erosion control measures must be selected, designed and installed to achieve seventy percent (70%) vegetative coverage within three (3) years.
B. For construction projects on land used for agricultural purposes (e.g., pipelines across crop or range land, staging areas for highway construction, etc.), final stabilization may be accomplished by returning the disturbed land to its preconstruction agricultural use. Areas disturbed that were not previously used for agricultural activities, such as buffer strips immediately adjacent to "water of the United States", and areas which are not being returned to their preconstruction agricultural use must meet final stabilization criteria.
FUGITIVE DUST: Particulate matter suspended in the air primarily from soil that has been disturbed by wind or human activities, such as earthmoving and vehicular and equipment traffic on unpaved surfaces. Fugitive dust does not include emissions from vents, chimneys or stacks.
HAZARDOUS WASTE: Any chemical, compound, mixture, substance or article which is designated by the United States Environmental Protection Agency or appropriate agency of the State to be a "hazardous waste", "hazardous material" or "hazardous substance", as those terms are defined by Federal or State law.
ILLICIT DISCHARGE: Any discharge to a storm drain system that is not composed entirely of stormwater, except discharges pursuant to an NPDES permit, discharges resulting from firefighting activities, and other exempt discharges as outlined in the Boise City stormwater management and discharge control ordinance.
LAND DISTURBING ACTIVITY: A human induced change to improved or unimproved land, including, but not limited to, new home or building construction, expansion of an existing building or home, demolition activity, clearing, grubbing, leveling, excavation, fill operations, clearing, trenching, landscaping, grading, drainage, pipe installation, drilling, mining, dredging, road construction or improvement, paving, construction of earthen berms, and improvements for use as parking or storage.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) PERMIT: A discharge permit issued by the U.S. EPA, Region X, in compliance with the Federal Clean Water Act and its amendments.
PDS: The Boise City Department of Planning and Development Services.
PERMIT: The erosion control permit issued by the Director of Planning and Development Services authorizing performance of a construction project.
PERMIT HOLDER: The person who applies his or her signature for an erosion control permit.
PERSON: Any individual, firm, association, club, organization, corporation, partnership, business trust, company or other entity which is recognized by law as the subject of rights or duties.

POLLUTION: The degradation of the physical, thermal, chemical, biological or radioactive properties of the air and the waters of the State or U.S.; the discharge of any pollutant into the air stream or waters of the State or U.S. which will or is likely to create a nuisance or to render such waters harmful, detrimental or injurious to public health, safety or welfare, or to domestic, commercial, industrial, recreational, aesthetic or other beneficial uses.

The notice will include the nature of the violation(s) and the required timeframe for correcting the violation. (Ord. 48-14, 12-16-2014, eff. 1-1-2015; amd. 2019 Code)



1. When background native vegetation will cover less than 100 percent of the ground (e.g., arid areas, beaches), the 70 percent coverage is adjusted as follows: If the native vegetation covers 50 percent of the ground, 70 percent of 50 percent (0.70 x 0.50 = 0.35) would require 35 percent total cover for final stabilization (e.g., on a beach with no natural vegetation, no stabilization is required).
