Flood Control Engineering: 385-468-6600 2001 South State, N3-120 Salt Lake City, UT 84190
(Revised April 14, 2005)
The permit application (form 1708) must be in the name of the person or entity (i.e.; City, Developer, Home Owners Association, etc.) that will be ultimately responsible for maintenance of the permitted system or facility. The complete mailing address of the Grantee must be shown in the address space. The phone number and name of the Contact Person at the project site must appear below the Grantee's name.
A mailing address for the Contact Person may be included on the line below "Address" if the Contact Person wishes to be copied on correspondence. All correspondence (i.e., review, additional requirements and approval notices) will be sent to the(se) mailing address(es) provided. A brief description of the project, including total discharge, street names and coordinates of the project site, must be given in the area provided.
Basin and flood control numbers are for Salt Lake County's filing purposes. On page 2 of the form, the Grantee or the "Authorized Agent" of the Grantee must sign indicating acceptance of the permit terms and any special conditions which may be added during the review and approval process. Please be sure to read the body of the application before signing as this will become a lifetime permit and provides specific remedies and permit termination requirements for both the County (Grantor) and the Applicant (Grantee).
In general, all applications should provide ONE SET of plan and profile drawings with topography contours of at most 2 ft, cross-section drawings of the listed facility at intervals of 50 to 100 feet (showing the 100 year flood elevation for both existing and proposed conditions), detail drawings or standard drawings or calls for any prefabricated items, and structural & hydraulic calculation worksheets as needed to fully describe the proposed project.
Hydraulic calculations for any work over, under, in or adjacent to any listed facility, or for any retention or detention facility, must use the 100 year event and identify flood flow rates and water surface elevations within the listed facility. You must determine storm runoff discharge rates for residential or commercial developments or other subdivision projects using 10 year events, or design storms as required by the applicable city building department or official. Because many of the flood control facilities are at or near their design capacity, all projects requesting a permit to discharge waters into listed County facilities will be required to detain storm water to the lesser of either the pre-development flows or the applicable city allowable discharge. This means that you must provide at least three (3) sets of calculations, one set for the pre-development conditions, one set for the post-development conditions and one set for detention pond sizing. Please check with the City Engineer's Office or the Flood Control Section of Salt Lake County.
Storm Water Pollution Prevention Plans are required for projects which disturb more than one (1) acre, and may be required for smaller projects. Geologic (Soils) Reports are required whenever the project involves the Jordan River Meander Corridor, or other projects when geologic hazards or site conditions warrant. Easements must be provided along the facility for flood control maintenance purposes, must be a width of twenty feet (6.1 meters) as measured from the top of the channel bank or outside edge of culverts, and may be shown on either the recorded plat or described in a recorded easement.
Copies of Permits, License/Encroachment Agreements, Right-of-Way Agreements or Temporary Easements from other Government or Private regulatory authorities are not required. Including these documents may, however, expedite the review and approval of your flood control permit application. Please refer to the section on the permitting process later in this guidance.
All engineered drawings must be stamped by a licensed Professional Engineer (P.E.), Structural Engineer (S.E.) and/or Land Surveyor (L.S.), dependant on the drawing type. Calculation worksheets also need to be stamped. All drawings submitted with the application must not exceed 24" by 36" ("D" size sheets), and must be folded to 8.5" by 11" size. Submitting Rolled drawings may result in extra charges ! A copy of the "APPROVED" permit application should be available for inspection at the project site during construction.
If your project involves a canal or natural stream that is not listed in § 17.08.040, you do not need a flood control permit from Salt Lake County. You will, however, need to speak with the Canal Company and the government agencies that have jurisdiction over your project site. If your project involves a canal or natural stream that is listed, you need a flood control permit from Salt Lake County, and may be required to obtain other permits through canal companies and government agencies (i.e.; Utah State Department of Natural Resources, Division of Water Rights or the U.S. Army Corps of Engineers).
Most Canal Companies require a separate agreement and fee. Permits from Salt Lake County, Utah State and the Corps for flood control and stream alteration are currently free of charge. The table that follows lists countywide facilities that have required a flood control permit since the program started in 1983. If the word "Removed" appears, that facility no longer requires a Flood Control Permit.
Although review time is dependant upon project complexity and employee workloads, most applications can be processed within a month.
A separate permit application must be made for each listed facility, although multiple sites on any one facility may be included on a single permit application.
Some municipalities and Irrigation or Canal Companies also have their own permit process for facilities that they own. Be certain to contact the owner before applying for a County Flood Control Permit to insure you've covered all the bases. The Flood Control Permit application does not require proof of other permits, but, providing this information may help expedite your approval.
DO NOT assume that an approved flood control permit from Salt Lake County will allow you to start construction. Although you may not start construction until Salt Lake County's flood control permit is approved, you may still need other permits from other government agencies or private property owners. You may also be required to post bonds and pay fees for those permits.
Once the application is completed and the supporting documents are attached, deliver the package to Salt Lake County?s Flood Control Permit Specialist. The Specialist will review the package for completeness and notify you immediately, or by e-mail, phone or letter, if the package is incomplete. Please ensure that the application form is signed by the Applicant or an Authorized Agent because the process can not be completed, and approval signatures can not be obtained, if the Grantee or the Agent has not accepted the general terms of the permit application.
If the application and documentation are in order, the Specialist will enter your application into the database and assign a control number. The Specialist will then notify you of the assigned control number by e-mail, phone or letter. Please use this number when corresponding or calling about your application.
The Specialist will perform a review of the package and request comments from other agencies, as applicable, regarding your application. If additional requirements or conditions are placed on the approval of your application, you will be notified by email, phone or letter. You may withdraw your application at any time prior to approval by asking the Specialist to cancel your application.
Once the Specialist has reviewed your application and comments from other agencies, he or she will sign the application recommending approval or denial. The application will then be forwarded to the Flood Control Operations Supervisor for his or her recommendation and signature. If the application involves an Irrigation Canal Company, the entire package will be reviewed with that company for it?s approval signature. In lieu of the Canal Owner's signature, the Applicant may submit copies of fully endorsed Canal Company permit(s) or agreement(s) as proof of Canal Company approval.
The application package will then be taken to the Division Director of Engineering. All comments and recommendations will be reviewed with the Director. This is the final approving authority for the application. The Specialist will then notify you as to approval or denial by email, telephone or letter.
After approval is obtained and the permit has been issued, you must abide by the terms and conditions contained in the permit, and notify the Specialist at least twenty-four hours before construction starts so that necessary inspections can be scheduled. Some permitted activities do not require inspections (i.e., Scout clean-up projects, landscaping only, etc.), whereas others may require multiple inspections (i.e., bridging projects, bank stabilization, etc.).
When a permit application is requested to install or extend box culverts, the following should be considered and documented:
