Drainage Design Manual - the City of San Luis Obispo

Legally it is up to the applicant to show that species are not impacted, and if the Corps isnot involved in the permit processing under a Nationwide Permit, or a RegionalProgrammatic permit, then the landowner must contact the USFWS or NMFS directly.“Taking” means destroying a species ability to breed, feed, or find shelter, and includestaking as result of a erosion/siltation, landslide, mudflow, or bank failure from a poorlydesigned and executed management action or construction project.The City and County environmental review officer will assist the applicant in determining whichpermits are necessary from which agencies, and how the project can be dealt with in an efficientand expedited fashion if it is consistent with this design handbook and the Stream Managementand Maintenance Program manual.Step 5 - Preparation and Submittal of Construction Plans and SpecificationsBoth the City of San Luis Obispo and SLO County have adopted the latest version of theCalifornia Department of Transportation (Caltrans) Standard Plans and Standard Specificationsas their basic design manuals. These contain very exacting standards and the same level of detailwill generally be necessary for Construction Drawings for private construction projects alongcreeks. The final approved Concept Plan and Design Report as modified during the permitreview and approval process will form the basis for preparation of the Construction Plans andSpecifications.Preparing formal Plans and Specifications, including the Engineer’s Estimate of Probable Costswill help ensure that the constructed project meets all of the project Goals and Objectives andconsiders all of the regulatory requirements and design constraints. For Public Works projectsthe Plans and Specifications should include the following: Contractual language including method of measuring work for payment, and applicableunit and lump sum costs, bonds and retentions; Method for change orders and payment provisions for unforeseen circumstances; Construction schedule and any penalties for delayed work; Detailed description of the Scope of Work; Materials specifications and suppliers list; Construction methods, tolerances and work requirements; Access, right-of-way, utilities, limits of work, mobilization and staging areas; Plan sheets, details, and typical cross sections; (following City/County EngineeringStandards) Notifications, submittals, and construction inspection; Regulatory requirements, permit conditions, and work restrictions;• Plan for water diversion and de-watering, and construction erosion control (SWPPP)• Plan for protection or relocation of sensitive aquatic vertebrate species and fish Post- construction maintenance and monitoring requirements.SLO Creek Drainage Design Manual 68 February 2003
