GRADIENT

The minimum and maximum gradients of any ROADWAY shall be 0.7% and 5%, respectively. The gradient at intersections shall not exceed 2% for the first 150 feet.

FINAL SURFACE COURSE ADJACENT TO NEW CONSTRUCTION

After commercial or industrial building construction immediately adjacent to the newly constructed pavement has reached a point where heavy construction traffic is no longer required or residential subdivision building construction has reached 80% completion, the previously installed binder, curb and sidewalk shall be inspected by the village engineer and any failures be repaired.  After such repairs have been completed, the hot-mix asphalt surface shall be constructed.  In no case shall the hot-mix asphalt surface be constructed until the base and binder course have been in place for a period of one year.  Any deviations from these requirements must be approved by the village engineer. 

CURB AND GUTTER

Curb and gutter shall be type B6.12. The curb face shall have the same depth as the adjacent pavement. At all locations where new curb meets existing curb, two (2) twelve (12) inch long by one half (1/2) inch diameter dwyidag dowel bars shall be installed. Depressed curb shall be provided at all sidewalk crossings, multi-use path crossings, driveway aprons and entrance drives. 

SIDEWALK

The construction of sidewalk and subgrade shall be in conformance with Illinois Department of Transportation’s (IDOT) Standard Specifications for Road and Bridge Construction (SSRBC) and all subsequent revisions thereto. All dedicated SIDEWALK, SIDEWALK to be dedicated, or SIDEWALK available for the use of the general public shall be constructed in accordance with the latest Americans with Disabilities Act (ADA) accessibility guidelines to the minimum standards.

• Four (4) inches of aggregate base and five (5) inches of concrete
• Sidewalk Width - 5 Feet
• Sidewalk shall be installed on both sides of each public roadway
• Sidewalk shall be installed one (1) foot from the property line whenever possible

MULTI-USE PATHS

The construction of Multi-Use Path pavement and subgrade shall be in conformance with Illinois Department of Transportation’s (IDOT) Standard Specifications for Road and Bridge Construction (SSRBC) and all subsequent revisions thereto. Multi-use paths shall be provided when shown in the Comprehensive Plan, when deemed necessary by the Village Engineer, and considered when an existing path is within a quarter-mile of the development boundary. Multi-use paths may be used in lieu of sidewalks on collector or arterial streets. Multi-Use Paths, all dedicated Multi-Use Paths, Multi-Use Paths to be dedicated, or Multi-Use Paths available for the use of the general public shall be constructed in accordance with the latest Americans with Disabilities Act (ADA) accessibility guidelines and shall be constructed to the minimum standards by classification.

Residential Local:

• Nine (9) inches of aggregate base with three (3) inches of Hot-Mix Asphalt surface course.
• Multi-Use Path Width – 8 Feet

Residential Collector/Commercial/Industrial District:

• Nine (9) inches of aggregate base with three (3) inches of Hot-Mix Asphalt surface course.
• Multi-Use Path Width – 10 Feet

OFF-STREET PARKING

Driveway and Parking Lot Pavement Accessory parking spaces may be open to the sky or enclosed in a building. All open or otherwise off-street parking spaces and maneuvering lanes accessory to any structure shall be improved with an all-weather material. The minimum requirements for vehicles shall be as follows:

SINGLE-FAMILY RESIDENTIAL DRIVEWAYS

Light Duty Pavement (i.e. automobiles):

• Asphalt - Six (6) inches of aggregate base and two (2) inches of Hot-Mix Asphalt or;
• Concrete - Four (4) inches aggregate base with four (4) inches of reinforced concrete

PARKING LOTS FOR MULTI-FAMILY, COMMERCIAL OR INDUSTRIAL COMPLEXES

Light Duty Pavement (i.e. automobile parking stalls):

• Asphalt - Six (6) inches of aggregate base with two and a half (2.5) inches of Hot-Mix Asphalt or;
• Concrete - Four (4) inches of aggregate base with four (4) inches of reinforced concrete

Standard Duty Pavement (i.e. automobile aisles/medium duty truck pavement):

• Asphalt - Six (6) inches of aggregate base with four (4) inches of Hot-Mix Asphalt or;
• Concrete - Four (4) inches of aggregate base with four (4) inches of reinforced concrete

Heavy Duty Pavement (i.e. heavy duty truck pavement):

• Asphalt - Six (6) inches of aggregate base with six (6) inches of Hot-Mix Asphalt or;
• Concrete - Four (4) inches of aggregate base with five (5) inches of reinforced concrete

In certain areas, where permeable soils are present and allow proper drainage, the Village Engineer or his/her assigned designee may permit the use of permeable paving materials, including, but not limited to, porous concrete, permeable interlocking concrete pavers, concrete grid pavers, and porous asphalt. Compacted gravel will not be considered as permeable pavement.

DRIVEWAY APRONS AND ENTRANCE DRIVES

Single-Family Residential Driveway Aprons and Multi-Family, Commercial and Industrial Entrance Drives located within the village’s Right-of-Way shall have the same minimum requirements as the adjacent private pavement per the vehicle use types listed above.

Aprons and Entrance Drives within the village’s Right-of-Way shall be of the same width as the adjacent private pavement.  Where Single-Family Residential Driveway Aprons meet the curb or roadway pavement, they may flare out up to two (2) feet on each side beyond the width of the pavement on private property.
