9.6795 Source Control Standards apply to…

(a) Fuel dispensing facilities and surrounding traffic areas where vehicles, equipment, or tanks are refueled on the premises.  A fuel dispensing facility is the area where fuel is transferred from bulk storage tanks to vehicles, equipment, and/or mobile containers.
(b) Exterior storage of liquid materials, for example chemicals, food products, waste oils, solvents, process wastewaters, or petroleum products in aboveground containers, in quantities of 50 gallons or more, including permanent and temporary storage areas. 
(c) All facilities that store solid waste.  A solid waste storage area is a place where solid waste containers, including compactors, dumpsters, and garbage cans, are collectively stored.  Solid waste storage areas include, areas used to collect and store refuse or recyclable materials collection areas.  Exempt are solid waste storage areas for one and two family dwelling and areas used for the temporary storage of wood pallets or cardboard. 
(d) Developments that stockpile or store high-risk or low-risk bulk materials in outdoor containers, as the terms “high risk” and “low risk” are in the Stormwater Management Manual. 
(e) Developments proposing the installation of new material transfer areas as defined in the Stormwater Management Manual, or structural alterations to existing material transfer areas, such as access ramp re-grading and leveler installations. Exempt are areas used only for mid-sized to small-sized passenger vehicles and restricted by lease agreements or other regulatory requirements to storing, transporting or using materials that are classified as domestic use, for example, primary educational facilities (elementary, middle or high schools), buildings used for temporary storage  and churches. 
(f) All development with a designated equipment or vehicle washing or steam cleaning area, including smaller activity areas such as wheel-washing stations. Development that is intended for the storage of 10 or more fleet vehicles shall include a designated vehicle washing area.
(g) All development projects that disturb property suspected or known to contain contaminants in the soil or groundwater. 
(h) All development with new covered vehicle parking areas, or existing parking structures that are being developed.  Exempt are single-level canopies, overhangs and carports.

9.6796 Dedication of Easements…
Stormwater easement standards apply to all land use applications and development permits that result in the construction of a city maintained stormwater management facility.

9.6797 Operation and Maintenance…
Applicants are responsible for operation and maintenance of all stormwater facilities. Failure to operate and maintain facilities is recognized as a public nuisance.

9.0803 (24) STORMWATER Adjustments…
Pollution reduction facilities treating stormwater runoff that will result from the water quality design storm may be adjusted upon a finding that the selected pollution reduction facility will treat as much of the runoff as possible and one of the following applies:

 1. The area generating untreated runoff is less than 500 square feet of impervious surface and is isolated from the pollution reduction facility;

 2. The area generating untreated runoff is less than 500 square feet of impervious surface and it is not technically feasible to drain the untreated runoff to the pollution reduction facility;

 3. Constructing pollution reduction facilities to treat the runoff from the area at issue would require removal of trees or damage to other natural resources; or

 4. The area generating untreated runoff is less than 500 square feet of impervious surface and limited access to the area would prevent regular maintenance of the pollution reduction facility.

Selection, design, and construction of pollution reduction facilities may be adjusted upon finding that all of the following requirements are met:

 1. The proposed alternative design will achieve equal, or superior, results for function (reducing pollution), maintainability and safety, and the proposed siting does not adversely affect structures or other properties. 

 2. The applicant’s written description of the proposed alternative design has been reviewed and approved by the City Engineer.  The description of the proposed design submitted for review must include all of the following information for each component of the proposed alternative design:

a. Size, technical description, capacity, capital cost, design life, construction process and costs, consequences of improper construction, operation and maintenance requirements and costs;

b. Data on the effectiveness of proposed alternative technologies, if available, including data from laboratory testing and pilot/full-scale operations, and information regarding the operations of any full-scale installations;

c. Any other available information about the proposed design, including peer review articles, scientific or engineering journals, and approvals from other jurisdictions. 

 3. The applicant has submitted a method and schedule for monitoring the effectiveness of the proposed design once constructed, and a schedule for its maintenance.

 4. The applicant has submitted a signed statement that the applicant will replace the alternative pollution reduction facility if the facility does not function as proposed.  

Flow control facilities treating stormwater runoff may be adjusted upon finding that the facility will control flow rates as much as possible and one of the following applies:

 1. The area generating untreated runoff is less than 500 square feet of impervious surface and is isolated from the pollution reduction facility;

 2. The area generating untreated runoff is less than 500 square feet of impervious surface and it is not technically feasible to drain the untreated runoff to the pollution reduction facility;

 3. Constructing pollution reduction facilities to treat the runoff from the area at issue would require removal of trees or damage to other natural resources; or

 4. The area generating untreated runoff is less than 500 square feet of impervious surface and limited access to the area would prevent regular maintenance of the pollution reduction facility.

Selection, design, and construction of flow control facilities may be adjusted upon finding that all of the following requirements are met:

1. The proposed alternative design will achieve equal, or superior, results for function (flow control), maintainability and safety, and the proposed siting does not adversely affect structures or other properties. 

 2. The applicant’s written description of the proposed alternative design has been reviewed and approved by the City Engineer.  The description of the proposed design submitted for review must include all of the following information for each component of the proposed alternative design:

a. Size, technical description, capacity, capital cost, design life, construction process and costs, consequences of improper construction, operation and maintenance requirements and costs;

b. Data on the effectiveness of proposed alternative technologies, if available, including data from laboratory testing and pilot/full-scale operations, and information regarding the operations of any full-scale installations;

c. Any other available information about the proposed design, including peer review articles, scientific or engineering journals, and approvals from other jurisdictions. 

 3. The applicant has submitted a method and schedule for monitoring the effectiveness of the proposed design once constructed, and a schedule for its maintenance.

 4. The applicant has submitted a signed statement that the applicant will replace the alternative pollution reduction facility if the facility does not function as proposed. 

Location, design, and construction of oil control facilities may be adjusted if the applicant can demonstrate that the selected oil control facility will achieve the same result as those listed in the Stormwater Management Manual.

Location, design, and construction of source control facilities may be adjusted if the applicant can demonstrate that the selected source control will achieve the same result as those listed in the Stormwater Management Manual.  Applicants seeking an adjustment must submit a completed authorization request form adopted as part of the Stormwater Management Manual.
