§ 23-135. Curb and gutter; hiker-biker trails; sidewalk.

(a)

Curb and gutter shall be required in the following circumstances:

(1)

Where the majority of individual lots abutting any road have a frontage of one hundred (100) feet or less;

(2)

Where any road abuts property in the process of development for multidwelling residential, commercial, or industrial use which is not being subdivided into individual building lots;

(3)

Where any road abuts property in the process of development for townhouses, cluster, or similar uses in which individual building lots are interior to the subdivision and the road abuts common or open space areas of the subdivision;

(4)

Where curb and gutter construction is required by traffic or pedestrian conditions as determined by the Director.

(b)

Hiker-biker trails. Hiker-biker trails with appropriate ramps may be required in accordance with the Design and Construction Standards within the road right-of-way along routes designated as such on the Adopted and Approved Countywide Trails Plan or Area Master Plans maintained by the Maryland-National Capital Park and Planning Commission. The Department will accept the trail for maintenance only where the trail is located within, or parallel to and touching, the road right-of-way, and upon completion and acceptance of the construction. In addition, the Director may require construction of such trails along primary residential, collector, arterial, and industrial-commercial roads. Except as provided in this Section, hiker-biker trails shall stay open or an alternate route shall be provided. A hiker-biker trail may be closed and no alternative route provided if a regulated utility, bi-county agency or the Department determines that it is not feasible to keep the sidewalk open or provide an alternative route.

(c)

Sidewalks. Sidewalks shall be required along urban roads in the following circumstances:

(1)

Arterials - both sides.

(2)

Collectors - both sides.

(3)

Commercial/Industrial - as determined by the Director.

(4)

Primary Residential - on one side. Where existing sidewalks are located on both sides of the street, construction of the sidewalks on both sides of the street shall be continued to the next intersection where the sidewalk construction will transition to one-sided construction. Except as provided in this Section, the alternate sidewalk shall remain open to pedestrian traffic. A sidewalk may be closed and no alternative route provided if a regulated utility, bi-county agency or the Department determines that it is not feasible to keep the sidewalk open or provide an alternative route.

(5)

Secondary Residential - on one side. Where existing sidewalks are located on both sides of the street, construction of the sidewalks on both sides of the street shall be continued to the next intersection where the sidewalk construction will transition to one-sided construction. Except as provided in this Section, the alternate sidewalk shall remain open to pedestrian traffic. A sidewalk may be closed and no alternative route provided if a regulated utility, bi-county agency or the Department determines that it is not feasible to keep the sidewalk open or provide an alternative route.

(d)

Sidewalks on State roads. Sidewalks may be required along all State roads that have concrete curb and gutter, or where it is required by the SHA. A permit issued by the Department will be required for this work where a SHA permit is not required.
