1 EENU OUNTY ROD OMMISSION OUNTY RIGHT-OF-WY STNDRDS (Originally dopted ) (Revised ) (Revised ) (Revised ) East Eckerle Road Suttons ay, Michigan These standards are adopted in accordance with and under the authority of M The following information is a general summary of Road ommission Standards and Specifications regulating the use of right-of-ways. The eelanau ounty Road ommission reserves the right to impose additional requirements for the construction of improvements in the county road right of way as the Road ommission may deem in the best interests of the Road ommission and the motoring public. Driveways The finished surface on a driveway approach shall slope down from the pavement edge at a rate of 4% back to the ditch centerline. This distance shall not be less than 8. See Sketch - on Sheet 3. The sides of a driveway shall slope down to ditch bottom at a minimum 3 on 1 slope in residential areas where the speed limit is 25 mph. In all other areas the minimum slope shall be 4 on 1. See Sketch - on Sheet 3. When required, culverts shall be corrugated steel or concrete pipe. End sections may be required. Plastic culvert is allowed only if steel end sections are used. Minimum culvert diameter is 12. ulverts longer than 30 must be at least 15 diameter. On primary (numbered) roads a culvert shall be at least 15 diameter. 20 flat landing shall be constructed behind road shoulder when requested. Maximum finished grade shall not exceed 10% unless approved by the Road ommission. Maximum width of a residential drive is 24. Driveway must intersect road at right angles with a variance allowed up to 20 degrees. Standard driveway radiuses are 15 to the road shoulder. paved driveway must have a 6 minimum paved shoulder beyond the radius and a 20 long taper. When asphalt or concrete is placed on the shoulder within 40 feet from an existing paved surface, the shoulder area between paved surfaces must also be paved. Paved residential driveway approaches shall be at least 2 thick (220 lbs/syd); concrete approaches shall be at least 6 thick. The ends shall be tapered or dubbed down to eliminate any sharp edge that might obstruct snow removal. The adjacent gravel shoulder shall be graded to be flush with concrete or bituminous when completed. ommissioners ontacts General ontact Info Jim alhoun - hairman Managing Director Dan Wagner, P.E.

2 Page 2 of 3 driveway shall not infringe upon a road intersection radius. Normally a drive shall be located a minimum of 15 from a property line unless it will function as a joint drive approach with the neighboring property. If sod or other landscaping material is placed at the edge of the road shoulder, it must be kept lower than the shoulder. Place topsoil, seed, fertilizer and mulch on all disturbed areas to prevent erosion. drive serving one or two single family residences will be considered a residential driveway. onstruction shall be in accordance with Sketch #1 or #2 as designated by the Road ommission at the time of issuing the permit. Driveways to provide access for vacant land or the cultivation of agricultural crops shall also meet these specifications. drive serving 3 to 14 residential units shall be considered a multiple residential driveway. onstruction shall be in accordance with Sketch #3 or #4 as designated by the Road ommission at the time of issuing the permit. paved surface will be required for any driveway serving 5 or more residential units. These driveway approaches shall be paved with asphalt at least 3 thick (330 lbs/syd); thickness of concrete approaches shall be as required by the Engineer. drive serving more than 14 residential units shall be considered a commercial driveway. onstruction of all commercial driveways shall be in accordance with Sketch #5 or #6 as designated at the time of issuing the permit. paved surface and MDOT type -2 concrete curb and gutter will be required for any commercial driveway. These driveway approaches shall be paved with asphalt at least 3 thick (330 lbs/syd); thickness of concrete approaches shall be as required by the Engineer. For multi-residential and commercial driveways a cash escrow deposit in accordance with the Road ommission s current fee schedule is required to guarantee completion. Sight distance requirements are normally measured within the existing road right-of-way. If sight distance is obtained by using land outside the right-of-way, then a clear vision easement and deed restriction providing vision and maintaining it in perpetuity shall be provided. No stormwater from a new drive will be allowed to run out onto the road or shoulder. In no case shall the rate of stormwater from developed sites flowing to the county road right-of-way be greater than that from the undeveloped site. ny change in use of the property (from undeveloped to developed, adding one or more residences, new or more intensive commercial) will require meeting the current standards of sight distance, drainage, width, slope and surfacing for a new driveway. n applicant proposing a high-volume commercial driveway may be required to provide a right turn deceleration lane and/or a passing relief lane to accommodate left turns into the proposed drive. and Division ct ll new driveways and parcels being created under ct 591 of 1996 must meet current SHTO requirements for minimum stopping sight distance lengths. Reductions to the required stopping sight distance will not be considered for type of road, side slopes, road grades or advisory speed (yellow) signs.

3 Page 3 of 3 If a new drive is to serve more than one parcel, the developer shall obtain a drive permit and construct the drive to the appropriate standards at the time the land division is approved. The Road ommission may require an engineered site plan for difficult or unusual site conditions to assure proper design and compliance with standards. Mailboxes Mailboxes are allowed in the road right-of-way as a public service. The face of the mailbox shall be placed a minimum of 6 off the edge of the blacktop or 1 behind the road shoulder, whichever is farthest from the centerline. Single mailboxes should be installed on 4 x 4 or 5 diameter wood posts or steel posts weighing less than 3 lbs. per foot. These supports should be embedded with no more than 24 in the ground. Multiple mailbox installations shall be placed on individual supports. The Road ommission will not be responsible for damage to mailboxes caused by snow removal operations. In the event the plow or the truck were to directly hit a mailbox the Road ommission will replace with a standard mailbox. Other Improvements The following activities are not allowed within the road right-of-way and are actively being removed: Filling of roadside ditches. Planting of trees, shrubs, seedlings or bushes of any kind. onstruction of any type of retaining wall or headwall along side of driveways. The placement of any type of fence. The placement of rocks, boulders or earth berms. The placement of signs, light posts or other encroachment considered by the Road ommission as hazardous. The Road ommission will not issue a permit to place a sprinkler system within the road right-of-way. Sprinklers shall not be allowed to water curbs, saturate the road grade or discharge flow onto any part of traveled portion of the road. If sprinkler systems are damaged, the Road ommission will not pay for repair or replacement costs. ltering, moving or removing road features (signs, pavement markings, culverts, pavement, shoulders, etc.) is not allowed unless approved in writing by the Road ommission. The Road ommission will issue permits to allow changes to road features only when Road ommission staff determines that the change(s) would be an improvement in the best interest of the motoring public. Note: If you are disturbing earth within 500 feet of a lake or stream, or planning to disturb more than one acre of land, a soil erosion control permit (ct 347) will be required. DEQ permit may also be required. If you are uncertain of additional permits please check with the Soil Erosion ontrol Office. :\Staff folders\engineer\driveway\row Standards ORD PPROVED.docx
