An Excavation Permit is required for all digging within the rights of way maintained by the City of Sunset Hills. This includes new driveway aprons that attach to city streets. This does not include private roadways on private property, but does include their connection within street rights of way. Such aprons are considered private attachments to the City's Street Network and therefor do not require inspection or meet City street pavement thickness requirements. Contractors are responsible to the property owner or companies that hire them for this work. Excavations within County roads or State areas are handled by those jurisdictions.
If you are a contractor doing work for a private home or utility, please list that information in the Property Owner's name and address lines of the form. Please show the closest address below the contractor and property owner's information. Please indicate the appropriate pipe and utility information. The length, width and subsequent area information applies to the work area being disturbed within the city's right-of-way. This will determine the deposit amount applicable for the excavation.
The Fee is $25.
In lieu of the next section, an Excel Spreadsheet has been prepared in an online version to help you calculate the deposit required.
You will need to know the length and width to calculate the amount of area (in square feet) you are disturbing within the city's right-of-way.
From the City Code, Excavation Deposits are calculated in the following manner:
Except as provided in the 3rd paragraph, before any permit within the purview of this division is issued by the street commissioner, the applicant therefor shall deposit with the city:
For each excavation up to 10 square feet, the sum of $50
For each excavation of more than 10 square feet and less than 50 square feet, the sum of $100
For each excavation in excess of 50 square feet, an additional $25 for each 10 additional square feet or fraction thereof
If, within 90 days after an excavation by the permittee, the permittee restores the pavement in satisfactory form, such deposit shall be refunded to him; otherwise the city shall use the deposit for the purpose of employing others to restore the pavement and surface, and the permittee shall be liable to the city for any cost in excess of the amount of the deposit, plus a penalty of 25 per cent of the total cost of restoration. If the deposit is more than sufficient to restore the surface, the city shall retain out of the excess an amount equal to 25 per cent of the cost of restoration and refund the balance, if any, to the permittee.
In lieu of the payment of the deposit required by first paragraph of this section, any person having occasion to make frequent openings or excavations, may post a bond with the city in the amount deemed proper by the street commissioner. Such bond shall be conditioned that said person shall restore the pavement or surface in satisfactory form. In such case, permits shall be issued for work from time to time upon application therefor. In the event of the permittee's failure to restore the surface within the time provided in the second paragraph of this section, the city may employ others to restore the surface and charge the permittee therefore with the same penalty as provided in the second paragraph of this section. The cost of the resurfacing charges incurred by the city will be deducted from the standing deposit.
Excavation Inspection Notes
Subgrade of all pavement
Backfill of areas under city pavement need to be in the form of 1" minus rock and compacted in 1-foot lifts.
An inspection is required before the placement of the pavement.
Contact the Street Superintendent 24 hours in advance of inspection at 314-842-6080.
Thickness is typically 8" of X-Mix and 2" of C-Mix
Asphalt patches need to be square cut with a pavement cutter
Vertical walls of patches need to be sprayed black (not merely placed via a pour pot & broomed) with SS-1 binder.
X-Mix need application in 3 lifts & compaction for the 8" thickness
C-Mix also has compaction for the final 2" surface lift.
Asphalt patches need to be permanent and require a perimeter CRF seal application.
If the location of an excavation in a concrete slab is 1/3 or more away from a lateral control joint, the entire concrete slab will need to be replaced
Concrete pavement thickness will need to be matched and are 7" or 8" throughout the city's network
Connection to existing joints will need #5 bars at 2-foot centers drilled at least to a 6" depth, then epoxy cemented into existing concrete slabs.
Vegetation re-establishment means grass is growing, not simply that seed and straw have been placed in the area.
The online City Code relative to excavations has many of the answers to other questions concerning Excavation Permits.
You can contact Trish Moore if you need additional information concerning an excavation permit. Also, you can contact Wes Searcy at 314-849-3400 or email him for information. The fee and deposit go to separate accounts and therefore need separate checks made payable to "The City of Sunset Hills." The deposit is refundable at the end of the job when the job is cleaned up and all vegetation and associated paving work has been re-established. A phone call needs to be made to City Hall for final inspection and subsequent release of the escrowed deposit.
