MAILBOXES
Mailbox structures are a unique issue. The OBJECTS WITHIN PARKWAYS section allows a
United States Post Office mailbox on a normal wood or metal post without a permit. Other
structures require a permit and an indemnification covenant.
MISCELLANEOUS ITEMS
All work areas shall be restored in accordance with these Public Works Standards.
Excavations outside of pavements remaining open overnight shall be protected each night; this
may be achieved by backfilling to grade or lighted banieades and fencing on all sides.
When the Village notifies a permittee of a failure in the work area (e.g., cave-in or settlement),
the permittee shall respond and permanently repair said work area within 2 calendar days unless I'
the failure poses a safety hazard, as determined by the Village Engineer, in which case the
permittee shall respond within six(G)hours.
i
Disturbed areas shall be limited to no more than 100 linear feet of open trench before backftlling
and.temporary repairs are initiated.
Care must be taken in job site parking to avoid damage to sidewalks, pathways, driveways, or
landscaping. Parked vehicles and equipment shall not restrict private property access nor hinder
sight distances for traffic or pedestrians.
i
Erosion and sediment control in and around work sites shall be in accordance with pertinent
Village requirements and documents. Inlet protection shall be provided at all inlets (within
paved or unpaved areas). Under no circumstances shall material be washed into storm drains.
Excess materiallsediment shall be allowed to dry and then removed by vacuum sweeper or
shoveling and hauled away.
OBJECTS WITHIN PARKWAYS.
The Village hereby establishes the following policy regarding objects within parkways:
A. Notwithstanding section 12-11 of the Oak Brook Code, items that are relatively mobile and
have low mass and low height are allowed within the parkway as a matter of right and do not
require a permit. Examples include grass, flowers, flexible reflectors, wooden lathe stakes
(often used to mark driveways in winter),and normal mailbox posts.
Section GEN ITEMS,Pale 2 of 8
�, i
E. Items that are more permanent than those contemplated in section A might be allowed within
the parkw y under a permit issued by the Village. This section addresses those objects that
are substantial enough to require a permit and justify engineering review and Village control
over what they are and where they go. Examples include sprinkler lines, light posts, small
identification walls, omatelsubstantial mailbox structures, "mirror" ornate mailbox-type
structures,and trees/shrubs.
Except for those items discussed in the preceding paragraph, a private clear zone of 10 feet
adjacent to the back of curb or edge of pavement (shoulder if one exists) should be
i
maintained. This does not include items that are or become Village property such as
hydrants, street trees, etc. This private clear zone can be occupied by objects smaller than
eight inches above the ground and which would not require a permit. This would allow j
applicants to place small items within the private clear zone that should not cause damage to
vehicles. Examples include small boulders or timbers.
The parkway beyond the private clear zone could by used by Applicants for other larger
objects such as light posts which would require a permit.
C. Items that pose safety hazards or interfere with the private clear zone within parkways are
prohibited within the parkway. Examples include larger boulders, vertical pipes, berms (as
defined in Village Ordinance),and private retaining walls.
I
{
RESTORATION OF GRASS AREAS
All areas covered with-rass prior to construction shall be sodded after construction. The Village
Engineer may allow seed depending upon the unique circumstances of a particular site.
STORM WATER
Detention Facilities
Re3trictor plates and short pipe sections are not permitted. The entire length of the outlet pipe
must be sired for the required detention release rate.

VILL�►GE ItEV'I�W Sc INSpION
The Village will review, permit applications as expeditiously as possible and correspond with
applicants, either by telephone or in person, to correct any deficiencies so that a permit can be
approved as soon as possible. Submittal of`.correct and complete application documents by the
applicant will speed the review and approval process.
Inspection services will be provided by the Village as necessary and upon request by permittees.
i wenty-four (?4, hours advance notice must be given. Also see "General Permit Conditions -
Engineering Permits Only"for further information. �
Patches will be approved based on their general appearance,complizince with these Public Works
Standards, and their "rideability". Rideability is defined as a leveling tolerance to within one-
quarter(1!4")inch at any point across the parch as it relates to the surrounding pavement surface.

FURPOSE AND OBJEC OBJECTIVES
i
It makes sense to use established transportation corridors and their rights-of-way to locate the
many utility services necessary to modem life. The public rights-of way should be used for the
public good. Providing reasonable access for utilities used by the public,while not lessening the
safety of the traveling public, is certainly a public good. Use of the right-of-way for purposes
besides vehicular and pedestrian traffic,however,must be controlled in the public interest.
Public right-of-way is a community resource, a part of the infrastructure which links activities
and places. The Village of Oak Brook is responsible for its streets and must establish control of
the public ways to ensure that a safe travel environment is maintained,that other facilities in the
public ways are not abused,and that best use is made of this resource. When work in the public
ways is not controlled adequately;the likely results are:
• Excavation made with no notice to the regulating agency.
h
• Excavation and restoration work done without retard to community specifications and jl
standards.
s
• Use of improper materials and methods for restoring a utility cut.
1
• Slow repairs that create inconvenience to the public with extended lane closures.
s
• Poor workr_*.anship in trench reinstatement and pavement restoration.
• Public dissatisfaction with traffic delays and interrupted services.
• Disruption of adjoining public facilities,such as undercutting gutters and sidev.-aiks.
• Damage to adjoining utility facilities disturbed by improper excavation.
• Increased maintenance costs form pavements which are cut repeatedly to access utilities.
• Increased danger for the public and excavators.
i
Section UTILITY, Page 1 of 3
i
771171 MOM"I'M
Therefore, it is recognized that there is a need to accommodate public or private utility
companies in the providing of public or private services; however, the Village must insure that
the primary purpose of the roadway, that being the passage of vehicular traffic, is maintained to
the greatest extent possible. The use of the roadway corridors by utility companies is secondary
to the movement of traffic. This policy strikes a balance between the public need for efficient,
safe transportation routes and utility services within these routes.
Thie utility policy has three primary objectives:
1. The Village must insure that the public safety is maintained and that public inconvenience is
minimized by establishing time constraints .for utility work, response time for utility repairs
within public ways and specifically to the pavements,and standards for work zone safety, j
I
2. Protect the Village's infrastructure investment by establishing repair standards for the
pavement when utility cuts are trade.
3. Effectively and efficiently manage all uses within the public ways.
This policy has been prepared as a part of the Public Woks Construction Standards to guide the
staff and utility companies in achieving the above stated objectives. The policy is intended to
provide general guidance only. Specific requirements will be developed based on site-specific
conditions. Also, as with any policy, exceptions may. be granted as deemed necessary by the i
Village. The Village will conduct periodic reviews of this policy and invites utility companies'
input in order to make this policy an effective tool for the conduct of our mutual responsibilities
to serve our respective"customers".
GENERAL STANDARDS
Any utility proposed to be located within or go through the drip lane of any tree designated by the
Village to be preserved shall be bored under or around.the row system; trenching is not
permitted.
The utility company receiving a permit is held responsible for the work performed and the
Village will contact the utility company for required adjustments or corrections regardless of
whether the utility company performed the work itself or subcontracted and assigned the work.
The permit is issued to the utility company and it is solely responsible for any work performed.
