The requirements for culvert placement states that "for all NWPs that involve the construction/installation of culverts, measures will be included in the construction/installation that will promote the safe passage of fish and other aquatic organisms. The dimension, pattern, and profile of the stream above and below a pipe or culvert should not be modified by altering the width or depth of the stream profile in connection with the construction activity. The width, height, and gradient of a proposed culvert should be sufficient to pass the average historical low flow and spring flow without adversely altering flow velocity." In addition culverts must be buried, to a certain depth depending on size, to maintain aquatic passage and to maintain passage during drought of low flow conditions. The Corps is in agreement with the state (Dave W.) and believes current installation of the culvert and riprap could restrict aquatic passage within the culvert. Therefore, the Corps along with the state recommend that the riprap be placed at the outlet as the plans show. Please provide written confirmation and pictures once the modifications to the culvert is complete. Let me know if you have any other questions.

DWR agrees that this may occur. However, the issue we have is with the placement of the riprap above the toe of the outlet. The plans do not show riprap higher than the bottom of the pipe. Therefore, we are requesting that the riprap be placed at the outlet as the plans show. Let us know when the repairs are complete. Thanks. Dave W.

Also, the rip- rap is higher than the bottom of the pipe but it is not higher than the sill.

The plans and narrative explain that riprap will be placed at the toe of outlet to dissipate energy at the existing blow hole. However, it appears that the riprap is actually blocking the bottom portion of the outlet, of which will likely prevent aquatic passage. Was there a particular reason for placing rip rap in this manner?
