Chapter 16.14 — SITE PREPARATION AND SUBDIVISION CONSTRUCTION

Prior to the issuance of a building permit, a grading plan prepared and signed by a registered civil engineer shall be submitted to the city engineer for review and approval. Grading plans shall show the elevations of the natural ground at all lot corners, the finished grade at corners, the finished pad elevation, finished floor elevations, rates and directions of all drainage swales, and finished sidewalk elevations at all front lot lines and existing topographic elevations and drainage direction one hundred feet outside the boundary of proposed project area and/or map.

A.

Minimum Slopes. The minimum rate of grade of all drainage swales on lots shall be one-half of one percent.

B.

Pad elevation, Residential. The building pad elevation of residential lots shall be established at a minimum of ten inches above the design sidewalk elevation at the low side of the lot. The finished floor elevation of slab floor houses shall be a minimum of sixteen inches above the sidewalk elevation. The pad elevation of all residential lots shall be established at least one foot above the sign water surface in an adjacent storm drain channel or the ponded surface in an adjacent sump for collection of storm drain waters. An exception to this rule may be permitted in the case of a tract served by a storm drain pump station.

C.

Drainage Scheme. No inter-lot or "cross drainage" shall be permitted. All lots shall drain their own water to the public street, public drainage facility, or natural drainage course without passing through or across an adjacent lot. No lot shall drain water over the bank of a flood control channel.

D.

Grading Exceptions. Specific exceptions to requirements subsections A—C above may be approved at the discretion of the city engineer. Exceptions are considered to be the case of an individual lot or at most a tier of lots and are not to be construed as extending to an entire subdivision.

E.

As-Built Grading Plan. Upon completion of grading operations the applicant shall furnish to the city engineer two prints of an as-built grading plan prepared by the applicant's engineer. In case no grading plan had been prepared and no grading permit had been granted, the applicant shall furnish to the city engineer two prints of a map signed by the applicant's engineer and certifying that no fills had been made on the lots or else two prints of a map prepared by the applicant's engineer showing the location and depth of all compacted or uncompacted fills that had been made.
