to the architect's practice, as provided for in Florida Statutes §481.229 (1981), as may be amended from time to time. The following information shall be required: (1) Hydrologic data including design rainfall, project drainage area, tributory offsite drainage area, percolation tests, existing and proposed impervious area and soil characteristics including depth to 00$00i4J wet season high water table (MSL). Soil boring at four hundred (4001) feet spacing to a depth of six (6') feet shall be provided. Alternate representative soil profiles may be used if approved in writing by the Public Works Director and if demonstrated to be from a reliable and generally recognized source. A one foot interval contour topographic map of development area including offsite area of sufficient size to indicate the general neighboring elevations and drainage patterns shall be provided. Justification for wet season water table assumptions shall be provided. (2) Hydrologic calculations for determining existing and proposed stormwater runoff. (3) Hydraulic data including receiving water stages, stage -storage and stage -discharge data for proposed retention and/or detention facilities, and percolation test data as per the following procedure: (a) The test holes shall be located as close as possible to the proposed location of exfiltration trench or other percolation facility (vertical and horizontal) and, if critical, to a depth two (2') feet below the water table (MSL) at the time of the test. (b) a hole for each test of approximately twelve (12") inches diameter (or as required for a maximum clearance of one-half 0") inch between the hold and the test casing) is excavated to the required depth and the casing is lowered into the hole with a minimum of twelve (12") inches extending above the surface of the grade. (c) The test casing shall consist of a pipe that is at least eight (8") inches in diameter with perfo- rations in approximately the bottom seventy-five (75%) percent of the length as measured from the surface. The bottom of the casing shall be pointed. Exfiltration incre- ments shall be measured with a suitable gauging device. (d) Fill the test bore to six (6") inches above the surface of the existing grade and run the test no later than two (2) hours after the level has exfiltrated to below surface of existing grade. In all cases test runs are to start only after the first two (2") inches have exfiltrated. If a dry season condition exists, the test shall begin when the soil is moist and a wet season condi- tion is simulated.
