Identify potential floodplain encroachments and channel stability issues.
3. 3.
Develop and define criteria and computational methods to be used for the hydrologic and hydraulic analyses of ditches, culverts, and bridges, including appropriate design standards and flood frequency.
If there are other hydraulic features, e.g. storm drains and curb/gutter, provide proposed design criteria for these features.
Criteria and methods should be consistent with Drainage Design Manual identified in section 6.9.2 as well as pertinent site-specific considerations.

Drainage
6.10.1 GENERAL 6.10.1 综述
The Design-Builder shall provide a well-drained corridor and a safe environment for the individuals who use and maintain the road.
The design and construction of all drainage structures and appurtenances shall adequately address functionality, durability, ease of maintenance, maintenance access, safety, aesthetic and protection against vandalism according to contract specifications and standards.
In fulfilling the requirements for drainage, the Design-Builder shall abide by and fulfill the requirements related to drainage features while at the same time meeting requirements of other required design elements on the project.
Drainage design should achieve the most effective and economical methods by which runoff water can be passed through and removed from the roadway.
The primary objective should be:
a) Maintain drainage pattern
b) Provide culvert opening for natural drainage channels
c) Prevent undue accumulation and retention of water upon and adjacent to the roadway
d) Provide the roadway against storm and subsurface water damage
e) Providing a safe driving surface for the traveling public
f) The Design-Builder shall be responsible for the drainage system along the project.
6.10.2 STANDARDS 标准 6.10.2
All design work shall be performed in accordance with the requirements of the standards listed in Table 6.10.1.
If there is any unresolved ambiguity in standards, obtain clarification from the Employer before proceeding with design. 不明确点：如果标准中有任何未解决的不明确点，在继续进行设计或施工之前，应先取得业主的澄清。
