Section XV-5435 - Primary Roads
Universal Citation: LA Admin Code XV-5435
Current through Register Vol. 50, No. 9, September 20, 2024
A. Primary roads shall meet the requirements of §5433 and the additional requirements of this Section.
1. Certification. The
construction or reconstruction of primary roads shall be certified in a report
to the office by a qualified, registered professional engineer. The report
shall indicate that the primary road has been constructed or reconstructed as
designed and in accordance with the approved plan.
2. Safety Factor. Each primary road
embankment shall have a minimum static factor of 1.3 or meet the requirements
established under
§2737 C
3. Location
a. To minimize erosion, a primary road shall
be located, insofar as is practicable, on the most stable available
surface.
b. Fords of perennial or
intermittent streams by primary roads are prohibited unless they are
specifically approved by the office as temporary routes during periods of road
construction.
4.
Drainage Control. In accordance with the approved plan:
a. each primary road shall be constructed, or
reconstructed, and maintained to have adequate drainage control, using
structures such as, but not limited to, bridges, ditches, cross drains and
ditch relief drains. The drainage control system shall be designed to safely
pass the peak runoff from a 10-year, 6-hour precipitation event, or greater
event as specified by the office;
b. drainage pipes and culverts shall be
installed as designed, and maintained in a free and operating condition and to
prevent or control erosion at inlets and outlets;
c. drainage ditches shall be constructed and
maintained to prevent uncontrolled drainage over the road surface and
embankment;
d. culverts shall be
installed and maintained to sustain the vertical soil pressure, the passive
resistance of the foundation, and the weight of vehicles using the
road;
e. natural stream channels
shall not be altered or relocated without the prior approval of the office in
accordance with applicable §5319-5323 and 5349;
f. except as provided in
§5435. A.3.b structures
for perennial or intermittent stream channel crossings shall be made using
bridges, culverts, low-water crossings, or other structures designed,
constructed and maintained using current, prudent engineering practices. The
office shall ensure that low-water crossings are designed, constructed and
maintained to prevent erosion of the structure or streambed and additional
contributions of suspended solids to streamflow.
5. Surfacing. Primary roads shall be surfaced
with material approved by the office as being sufficiently durable for the
anticipated volume of traffic and the weight and speed of vehicles using the
road.
