Dear Mr. Norton:
Robert C. Schmidt, P.E.
Ed Addicks, P.E.
The purpose of this letter is to acknowledge that the construction plans for the streets and drainage for
the above-referenced project, to the best of my knowledge, do not deviate from the B/CS Design
Guideline Manual except as follows:
1. The asphalt street pavement is 1 Yi'' thick, being that the street is a park entrance road only.
(Previously approved by Alan Gibbs).
2. The fall across storm sewer inlet boxes and junction boxes is 0.05' instead of 0.1 '. (Previously
approved by Alan Gibbs).
3. The longitudinal slope of the drainage channel is less than 0.6%. A 0.6% longitudinal slope
cannot be achieved because of topography. A longitudinal slope steeper than the designed
slope with the designed channel section will result in a velocity exceeding the allowed
maximum velocity for the type of channel bottom.
There are no potable water or sanitary sewer improvements in the project.
The Civil General Notes on sheet C-1 of the plans specify that the City's General Specifications, Street
Specifications, Drainage Specifications, Standard Drainage Details, Standard Street Details, and
Standard Storm Water Pollution Prevention Details are incorporated into the project specifications by
reference with the exception that the street pavement section as recommended by the Geotechnical
Engineer and prepared by the Project Engineer (on Sheet C-8) applies to this project and that the City's
Standard Street Detail typical street section does not apply.
Sincerely,
Robert C. Schmidt, P.E.
Vice President
