An excavation permit is required for work in the right-of-way associated with driveways (new or existing) and sidewalks (constructed, repaired or replaced).
It is unlawful for any person to dig up, break, cut, excavate, tunnel, undermine or in any manner break up any street or to make or cause to be made any excavation in or under the surface of any street for any purpose or to place, deposit or leave upon any street any earth or other excavated material obstructing or tending to interfere with the free use of the street, unless such person shall first have obtained an excavation permit therefor from the Clerk as provided in City Code Chapter 278.
If you have any questions as to whether you need a permit, call the Engineering Department at 319-743-6340.
DRIVEWAY:
Per City Code, only one entrance for a single family residential property is allowed. The City engineer may approve additional entrances if the house is on a corner lot, has an extra wide lot or is located on a heavily traveled road.
Entrance width dimensions measured at the property line are as follows:
- 24 feet maximum for a one- or two-stall garage
- 36 feet maximum for a three or more stall garage
- Exception: 24 feet maximum width allowed on cul-de sac bulbs
Submit a driveway site plan and include the following details:
- Width of driveway and location at the sidewalk.
- Sidewalk bench location dimensions from property line.
- Flares and driveway approach location dimensions from the side property lines.
- Width of driveway opening at the street.
SIDEWALK:
In order to comply with ADA (Americans with Disabilities Act), all new sidewalks and replacements of existing sidewalks shall have a minimum width of 48" and a cross slope of 1.5% (2.0% maximum). Upon completion of the sidewalk work the City Engineer’s office shall be notified and a representative shall review the sidewalk for ADA compliance. In the event that a sidewalk is constructed outside of ADA compliance the sidewalk shall be removed and reconstructed meeting ADA standards.
PERMIT FEES:
- $30 = excavation does not affect the paved portion of the right-of-way
- $40 = excavation involves disturbance of the street or curb
- For new construction homes, permit fees are included with the Building permit
Note: Beginning work without an approved permit will result in a penalty. Fees may double if notification and/or inspections are not performed.
