City of Frisco Engineering Standards

Engineering Standards
a. A change in use, or an increase in intensity of use, occurs such that the site requires a ten
percent (10%) increase in required parking spaces.
b. Addition or expansion of required stacking spaces.
c. Any modification that changes the design or function of the existing driveway.
d. The addition of a median opening on the public street by a developer. All driveways that
are served by the new median opening shall comply with the requirements of these
standards.
2. Upon the occurrence of the events described above, the nonconforming driveway shall either

2.06 Sidewalk Location and Design
A. Definition of Sidewalk – A sidewalk is defined as the paved area designated for pedestrian use
which is generally located between the curb of the roadway and the adjacent property line. The
inside edge of the sidewalk is the edge closest to the street while the outside edge of the sidewalk
is farthest from the street.
B. Sidewalk Design – Sidewalks shall conform to the most current federal, state, and local ADA
requirements and to the following standards:
1. Sidewalk Grade – The maximum grade of the sidewalk shall be five percent (5%) or the
grade of the adjacent street, whichever is greater. The maximum cross-slope of the sidewalk
shall be two percent (2%).
2. Zoning Classification Requiring Sidewalks – Concrete sidewalks designed and located
according to City standards shall be constructed along all streets in all zoning classifications
except agriculture uses in agricultural zoned areas. Prior to developing any single-family,
duplex, or townhome residential lots, residential developers shall build sidewalks along all
streets adjacent to the subdivision and along the portions of any street within the subdivision
where residential lots do not front or side onto the street. Sidewalks along residential lots
shall be constructed by the homebuilder at the time each lot develops. Sidewalks adjacent to
non-residential and multi-family land uses shall be built at the time of lot development.
3. Hike and Bike Master Plan – Sidewalks shall be constructed with the width specified in the
Hike and Bike Master Plan along thoroughfares that are designated as off-street hike and bike
trail routes.
4. Type A and B Thoroughfares – A concrete sidewalk, a minimum six feet (6’) in width, shall
be located along all Type A and B thoroughfares. The sidewalk should typically be located
within the street ROW, but may extend into a sidewalk easement. The inside edge of the
sidewalk shall be no closer than five feet (5’) from the back-of-curb.
5. Type C, D, E, F, and G Thoroughfares – A concrete sidewalk, a minimum five feet (5’) in
width, shall be located along all Type C, D, E, F, and G thoroughfares. The sidewalk shall be
located within the street ROW unless pre-existing physical encroachments (e.g., utility
infrastructure or trees) dictate otherwise. The outside edge of the sidewalk shall be located
two feet (2’) inside the ROW line on Type C, D, and E thoroughfares. On Type F and G
