April 3, 1995 37 . The Municipality or owner has the responsibility to trim all plantings and to maintain visibility. Hennepin County's responsibility for landscape/streetscape restoration, after any County activity, shall be limited to top soil, sod or seed. Restoration of specialty landscape/streetscape items, sidewalks and plantings shall be the responsibility of others. The Division prefers traffic control signage to be located behind the sidewalk. Landscape/streetscape should not obstruct the view of signage. Landscape/streetscape should make allowances for placement or future expansion of utilities within the right of way. Traffic control during maintenance of landscaping shall comply with MMUTCD for traffic control. • Medians The Division can supply typical design standards for raised and depressed medians. Median drainage is a concern of the Division and should be discussed with the Division's Design Section. The Division's guideline does not allow planting trees within the median unless there is the minimum operational clear zone for the posted speed limit (see Operational Clear Zone). Plantings, including raised planting beds, in medians shall not be higher than 3 feet from the bottom of the curb gutter line, however, sight lines must still be checked. Plantings should be kept as far back from the face of curb as possible to minimize disturbance due to snow plowing (see also Irrigation). If the Municipality proceeds with placing plantings within Hennepin County right of way, then the Municipality has the responsibility to trim plantings to maintain sight lines. • Operational clear Zone To facilitate the safe operation and maintenance of a roadway facility, an operational clear zone is required. Encroachment into the operational clear zone causes safety and maintenance concerns. The Division standard provides an operational clear zone of 6 feet from the face of curb where posted speeds are 35 miles per hour (MPH) or less. For speeds greater than 35 MPH to 45 MPH, the Division standard provides a 10 foot operational clear zone. The required operational clear zone for speeds over 45 MPH shall be analyzed on an individual basis by the Division (see Figure 1). • Right of Wav Streetscape/landscape items within the County's right of for the public and owned by the Municipality.
