April 3, 1995 • Crosswalks Crosswalks shall conform to the Minnesota Manual on Uniform Traffic Control Devices (MMUTCD). The County's standard crosswalk is a block type pattern, painted white, on top of bituminous or concrete pavement. Municipalities have the responsi- bility to maintain pavement crosswalk markings, after the initial painting. Non-standard crosswalk surfaces (such as decorative brick, colored aggregate, etc.) shall require prior approval by the Division. Municipalities shall have the responsibility to install and maintain any crosswalk surface, as well as the abutting material, if the crosswalk surface is not consistent with the road surface. The municipality shall also indemnify the County for the use of a non-standard crosswalk surface. Curb Curb design must conform to Hennepin County's Standard Design and the State Aid manual. Curb and pedestrian ramps must comply with the Americans With Disabilities Act (ADA). • rrriaation Water from irrigation systems shall not flow or spray onto the traveled . roadway or onto any County owned structures such as traffic signal components and signage. Concrete gutters shall collect excess water from irrigation systems and not allow water to flow across roadways (gutter in). Effects of subgrade saturation shall be addressed when irrigation systems are proposed. Provisions, such as perforated pipe, shall be included for the pickup and disposal of irrigation water. The Division will not allow an open cut for installation or maintenance of irrigation piping within three years of construction, so consideration should be given to installing irrigation piping within a sleeve for roadway crossings. Maintenance and repair of the irrigation system is the responsibility of the owner. • Landscaping/Streets caping Roadway geometrics and driver sight distances shall be considered when installing landscape items. A report indicating adequate sight distances have been maintained is required for all access points along the project. The report should consider all elements obstructing a driver's vision such as trees, shrubs, plantings/planters, .structures, etc. Any loose landscaping material, such as bark, must have an adequate means of containment that will prevent the material from spilling onto the roadway or sidewalk. The Municipality shall be responsible for maintaining such material, if installed, and for removing the material from the roadway or sidewalk if the material spills onto those surfaces. Loose landscape rock is not permitted within Hennepin County's right of way because of problems caused during mowing, etc. -2- 36 1-lennepin County Agreement No. PW 59-10-07 Exhibit "B"; Sheet 4 of 8 W
