| City of Knoxville
Stormwater Engineering Division
The Stormwater Engineering Division is part of the
plans review process for any development / grading / construction
within the City of Knoxville. Chapters 1 and 2 of the Land
Development Manual explain the role of the Stormwater Engineering
Division in terms of plans review and final plat review. A developer
will receive a Site Development Permit upon approval of drawings and
computations relating to the design of site grading, street construction,
stormwater drainage, stormwater quality, erosion control, easements,
etc. The Site Development Permit is not issued until satisfactory
performance bonds are posted and the final approved plat is recorded.
In addition to consulting the Land Development Manual, many types
of questions can be answered in the Minimum Subdivision Regulations
and the Knoxville Zoning Ordinance, which are maintained by the
Metropolitan Planning Commission (MPC).
The most common points of contact at the Stormwater Engineering
Division 865-215-2148 during site design and construction are:
|Plans review, design questions
||Chris Howley, Aaron Kline or Charissa
|Stormwater quality design & maintenance
review, easements, covenants
||Molly Hyatt or Ben Davidson
|Field inspection &
|Construction bonds, covenants, agreements
A project must have a valid street address assigned by MPC before the
site plans are accepted for review. Submit two sets of site development
plans to City of Knoxville Engineering Department (Suite 480, City County
Building), along with roadway profiles, stormwater detention calculations,
retaining wall calculations. See Appendix A of the Land Development
Manual for the Site Development Permit Application and the Site Development
Review Checklist. Four complete sets of drawings are needed when all
drawing revisions have been completed.
When the customer submits the site development plans, a tracking
number is assigned and entered into the submittal log. The customer
pays the appropriate review fee, and fills out the information on
the Site Development Permit Application. A submittal packet that contains
permitting information documents is given to the customer. One of
the documents, "Requirements for Permitting Projects With Water
Quality Facilities", must be signed by the property owner
and then returned to the Engineering Department.
In addition to the Land Development
Manual, the Stormwater Engineering Division has prepared a
entitled "Water Quality Requirements for New Development" to
summarize the major considerations for design of stormwater detention
and quality facilities.

COK technical specifications are not meant to cover every situation
or design need, and only address general requirements for which additional
drawings, details, and cross sections must be prepared and stamped
by a design professional engineer or landscape architect registered
in the state of Tennessee. Construction of buildings, houses, apartments,
stores, etc. are not addressed in the COK technical specifications.
Most terms and abbreviations are not explicitly defined within the
specifications if commonly used in the practice of civil engineering.

Safety considerations should always be a top priority when designing
site plans and specifications. Anticipate all safety issues related
to phased construction such as traffic control, parking, equipment
maneuverability, site access, material storage areas, types of fences
needed, presence of neighborhood children, and grading.
A few typical safety points to emphasize include:
Temporary or permanent electrical work must be performed by licensed
contractors. Use GFCI and other required types of equipment for
safety; protect electrical lines to the maximum extent possible.
For utility trenching and grading slopes, always specify that
the contractor (and all subcontractors) must obey regulations in
OSHA 29 CFR 1926, Subpart P - Excavations.
Use the Tennessee One-Call
Center (1-800-351-1111) for utility location at least 3 working
days prior to excavating.
