Angle of intersection. Every driveway shall meet the edge of the roadway/highway pavement at an angle of no less than 75° and shall adhere to this angle for a minimum of 50 linear feet as measured from the center line of the existing roadway/highway.
B.
Grade at intersection. Every driveway shall have a finished grade of not more than 4% extending a distance of 20 feet from the edge of the roadway/highway pavement (travelway).
C.
Maximum grade. No driveway shall contain any portion having a grade greater than 12% along the length. No driveway shall contain any portion having a grade of more than 5% across its width. An as-built survey to include driveway and embankment grades and associated drainage may be required under questionable circumstances as determined by the Town Engineer and/or the Director of Public Works.

Drainage; culverts.
(1)
Drainage. No driveway shall be constructed or maintained so as to discharge water into any Town roadway and/or any abutting properties. No driveway shall be constructed or maintained so as to allow roadway water to enter the main portion of the driveway. Driveway design shall provide drainage best management practices and erosion and sedimentation control measures. No driveway shall be constructed so as to allow untreated water to enter an inland wetland or watercourse.
(2)
Culverts. Where determined necessary to control drainage, a culvert may be required for a driveway entering a Town roadway/highway. Said culvert shall be a minimum of 20 feet in length or a minimum of four feet wider than the driveway on each side.

E.
Minimum width. All driveway shall have a minimum width of 10 feet and shall be at least 14 feet across, where adjoining any Town road/highway.
F.
Pavement at intersection. All driveways must be paved to streetline or for a length of 10 feet; whichever is greater, from the point that they meet the existing roadway pavement. This pavement shall be a minimum two-inch depth of bituminous concrete on a six-inch processed aggregate base approved by the Town Engineer and/or the Director of Public Works.

The measurement of the sight line distance shall be based on a three-and-five-tenths-foot height of eye and a four-and-twenty-five-hundredths-foot height of the approaching vehicle. The sight line shall be measured 10 feet minimum from the edge of the Town road.
I.
Separation from intersection. No driveway shall be located within 20 feet of a street intersection or within five feet of an established or proposed crosswalk.
J.
Intersection with a state highway. All driveways entering state highways shall also conform to the specifications set forth by the State of Connecticut Department of Transportation. The applicant shall obtain said permit from the State of Connecticut Department of Transportation.

The Director of Public Works shall consult with the Town Engineer regarding erosion control. Every reasonable precaution shall be exercised throughout the period of driveway construction to prevent, control, and abate siltation, sedimentation, and pollution of all waters. Unless a specific type of sedimentation control system is ordered by the Town Engineer, the type of system will be as designed by a State of Connecticut licensed professional engineer (aka Design Engineer) as shown on the site plan. The Design Engineer shall submit an erosion and sedimentation control bond estimate for all work associated with the installation of the driveway to include stormwater management. (See Subsection D(1) and (2) above.) The erosion and sedimentation control bond estimate shall be reviewed by the Town Engineer, who will determine the final bond amount. Geotextile silt fence, hay bale systems, and/or tubular sediment control products will be allowed to remain at the toe of slope areas unless ordered removed by the Town Engineer, the Director of Public Works, and/or the Zoning or Wetlands Enforcement Officer. All erosion and sedimentation control measures shall be maintained by the property owner/permittee.

Erosion control blankets and/or turf reinforced matting may be required in areas deemed critical by the Town Engineer, Director of Public Works, and/or the Zoning or Wetlands Enforcement Officer. All erosion and sedimentation control measures shall remain in place until all disturbed areas have an established permanent vegetative cover (70% turf establishment).
