STORM WATER UTILITY SERVICE CHARGE CREDIT PROCEDURE AD APPLICATIO Introduction Murray City Storm Water Utility Ordinance defines the rates to be charged by the Utility. The ordinance allows fee credits to be granted to non-single-family residential property owners for on- site mitigation, which either reduce the quantity or improves the quality of the storm water runoff. The premise behind the storm water credit is that some properties with on-site quantity and quality facilities do reduce the City's actual storm water management costs. An analysis of the Utility costs show that fifty-five percent (55%) of planned expenditures are fixed program expenditures and are not affected by water quantity or quality and forty-five percent (45%) of planned expenditures are variable and directly related to storm water flows and water quality. The maximum fee credit has been set at 45%, thus all properties, at a minimum, will contribute to the cost of meeting the Utility’s fixed costs. Any non-single family residential property owner that has installed or is operating on-site "retention" or "detention" facility that exceeds City standards may apply for a service fee credit of up to 25%. A service fee credit of up to 20% may also be applied for, for implementing City- approved Best Management Practices or BMP’s, which reduce or eliminate pollutants for its storm water runoff before it enters a storm drain, irrigation ditch, dry well (sumps), or creek or river. A list of BMP’s are attached to this document. Sumps are exempt from water quantity fee credit. Application Procedures The property owner or authorized agent must make application for this credit to the City Engineer or his designee. If a request for credit is granted, the credit will be applied to all charges from the time of filing a complete credit application and will be deducted on the next billing thirty days after the credit is granted. If the credit is not granted, a meeting can be scheduled with the City Engineer to review the application. Storm Water Quantity Credits Storm water control facilities located on a property may either hold runoff for a period of time and release it at a controlled rate to the storm water system (detention), or hold water until it evaporates or infiltrates into the ground (retention). The control facility must exceed standard City requirements to be eligible for the credit and the credit amount may be up to 25% of the total service fee based on the following formula: Credit % = 25[(0.2-q)/0.2] Where: 25 = Percent costs related to the Utility’s storm water quantity program. 0.2 = Maximum allowable storm water discharge rate from a parcel in cubic feet per second per acre (cfs/acre). q = Peak storm water discharge rate from parcel in (cfs/acre). ---PAGE BREAK--- Calculations and a site plan will be required showing retention and detention areas, volumes and discharge rates for a 10 year 24 hour storm event. Storm Water Quality Credits In order to qualify for the storm water quality credit, a non-single family residential property may implement source or treatment controls which reduce or eliminate pollutants from its storm water runoff before it enters the City’s storm water system. These source or treatment controls are known as Best Management Practices (BMP’s) applicable in whole or in part to specific types of operations. The amount of credit will be a function of the BMP’s which are directly applicable to the property and implemented on the site and which have been approved by the Utility. Based on the value assigned to the implemented best management practices by the Utility during an on-site consultative review with the applicant, the storm water quality portion of the credit amount may be up to 20% of the total service fee. (A list of Best Management Practices is attached to this document. Detailed descriptions and definitions of the BMPs are available in the “Guidance Document for Stormwater Management” developed by Salt Lake County Public Works Department which can be accessed on line at www.co.slc.ut.us/pw/engin/bmp/pdf/mmatrix.pdf . CODITIOS All service fee credits will remain in effect as long as: • The property owner has obtained the permits required by the City and the facility has been constructed in compliance with all approved plans. • The property owner remains responsible for all costs of operation and maintenance of the facility and/or best management practice. • The City will have access to the storm water facility and/or best management practices for purposes of inspecting its compliance with design, maintenance and operating standards. ---PAGE BREAK--- STORM WATER PROGRAM SERVICE CHARGE CREDIT APPLICATIO FORM Please complete the following application and return the information to the address listed below: Site Location: Street Address City State Zip Authorized Contact: Name & Title (last, first and title) Contact Mailing Address: Street Address City State Zip Phone Non-Residential Property?
