  • Sidewalk Construction Standards
    OSHTEMO TOWNSHIP SIDEWALK/SHARED-USE PATH CONSTRUCTION STANDARDS Approved August 28, 2018 CONCRETE SIDEWALK CONSTRUCTION The construction of Sidewalks and Shared-Use Paths within Oshtemo is managed through the Township’s issuance of a Sidewalk/Non-Motorized Path Permit. The permitting process includes both a pre-pour inspection of the base and concrete forms, and a final project inspection for acceptance of the work. Concrete sidewalk shall conform to MDOT 2012 (or current edition) Standard Specifications for Construction Section 803, "Concrete Sidewalks, Sidewalk Ramps and Steps" and shall be a minimum of five (5) feet wide unless a different width is required by other Township ordinances or regulations. Driveway Sidewalk Crossings Where public sidewalks (AKA pedestrian route) cross residential driveways, the sidewalk shall be constructed of concrete through the driveway. Where a curb-line concrete gutter pan begins the driveway, the driveway apron between the curb and sidewalk shall also be constructed of concrete. Hot-Mix Asphalt (HMA) commercial driveways that lack a concrete roadway gutter, and which have greater than two lanes or heavy traffic may seek administrative approval to establish a pedestrian route over the driveway in lieu of placing a concrete walkway through the HMA material. When new sidewalks are extended through existing driveways, it shall be administratively determined by the Township to what extent the existing driveway pavements will need to be reconstructed in lieu of providing a pedestrian route over the pavement. Grade The sidewalk shall be constructed to match the existing grade, or as noted on the construction drawings. The sidewalk will have a transverse slope either toward or away from the road to maintain existing drainage patterns.

  • Smart Crosswalk™ Automatic Activation Bollards
    SPEC Sheet #3000 Features/Benefits: Aesthetically pleasing Optional audible sounds Smart Crosswalk™ Automatic Activation Easily installed on sidewalk Simple control panel installations Bollards 12 VDC operation (down to 9 VDC) Automatic Activation Series — Bollards Internally illuminated courtesy light LightGuard Systems Part Number: LGS-T3A Directional detecting infrared sensors Description: Automatic Pedestrian Detection Bollards Application Notes: Infrared sensors are housed inside the Bollards and are typically preset by our factory. However, adjustments to the alignment of the sensor modules may be changed in the field. The infrared light beams are projected to the respective receiver module. The Bollard system is directionally sensitive and is activated only when a pedestrian enters into the crosswalk zone not when exiting. A pair of Bollards are placed at each end of the crosswalk, usually four bollards per crosswalk. When pedestrians enter into a crosswalk zone they pass between the Bollards and the Smart Crosswalk™ system is automatically activated. Each Bollard has a 24/7 LED courtesy light making the Bollard visible at night or during inclement weather. In order to capture the most pedestrians crossing the street, it is recommended that the bollards be placed a few feet wider than the crosswalk. General Performance Specifications Parameter Value Maximum separation 60 Feet Power consumption 2.5 Watts Operating temperature -20° to 80°C Operating voltage 9 VDC to 15 VDC Color White (custom colors available) Courtesy light color Amber Size 42” Tall, 8” Diameter © 2016 LightGuard Systems®, Inc.

  • Chapter 7, Driveways
    Chapter 7 - Driveways Publication 13M (DM-2) CHAPTER 7 DRIVEWAYS 7.0 INTRODUCTION It is in the public interest to regulate the location, design, construction, maintenance and drainage of access driveways, local roads and other property within State highway right-of-way for the purpose of security, economy of maintenance, preservation of proper roadway drainage, and safe and reasonable access for both vehicles and pedestrians crossing driveways. Driveways allow vehicles to ingress and egress streets at approved locations. In many locations, driveways will be required to cross pedestrian sidewalks within the roadway right-of-way. Driveways serve the same basic purpose for vehicles as curb ramps serve for pedestrians. Driveway crossings must be designed so that both drivers and pedestrians are able to use them effectively. The requirements and regulations for driveways must meet the requirements of the latest edition of the Pennsylvania Code, Title 67 - Transportation, Chapter 441 entitled "Access to and Occupancy of Highways by Driveways and Local Roads" (67 PA Code § 441). No driveway must be constructed or altered within State highway right-of-way without first obtaining a highway occupancy permit from the Department. The provisions of 67 PA Code § 441 contain the general conditions that apply to highway occupancy permit application procedures, fees, and permit issuance, general driveway design requirements and the general rules for penalties or revocation of permits based on violations pursuant to 67 PA Code § 441. The Americans with Disabilities Act (ADA) of 1990 also requires that all pedestrians including persons with disabilities be able to safely use sidewalks that cross driveways.
