All street pavements within the City of Tamarac shall consist of an 8-inch (compacted thickness) No. 2 Limerock Base and a 1 inch (compacted thickness) Type 1 Asphalt Concrete Surface Course. (1) No. 2 Limerock Base shall be Miami Limerock Grade No. 2 having a minimum percentage of carbonates (calcium and magnesium) of 70% with liquid limit not to exceed 35 and plasticity index no higher than 6. The carbonate content requirement may be reduced to a minimum of 50% if the subdivider can furnish the City Engineer with testing laboratory data indicating that the material to be used has a minimum LIMEROCK BEARING RATIO of 125% and will certify that all of the material to be used on the project in question will come from the same source as indicated by the test results. Test data and results will be accepted by the City Engineer only if the tests were conducted by a recognized testing Laboratory not more than thirty (30) days prior to submission for approval. In the event the placing of base material is not completed within the thirty day period beginning with the date of the approved LBR test, the subdivider shall submit additional test results each and every thirty days thereafter until all of the base material has been placed. (2) Compaction and density requirements shall be as follows: The full depth of the base shall be compacted to an average density of 98% of maximum density as determined by AASHO T 180 (Modified Proctor). The minimum density acceptable at any location shall be 96% and in determining the 'job average', 102% shall be the maximum used. (3) The surface course shall consist of a 1-inch layer of Type 1 Asphaltic Concrete as specified in Sections 320 and 331 of the Florida State Road Department 'Standard Specifications for Road and Bridge Construction.' A tack coat will be required as specified in Section 300 of said specifications. As the placement of the Limerock Base proceeds and the developer indicates the area is compacted and ready for testing (carbonate and density tests) the City Engineer shall specify locations for testing and the tests to be conducted. The City will pay for Carbonate and Density tests authorized by the Engineer which indicate conformance with these requirements. All tests which fail to show conformance shall be back charged to the subdivider and payment for same shall be made prior to the issuance of certifi- cates of occupancy or release of the Subdivision Bond, whichever comes first."

Mains smaller than 6-inch may be constructed of the aforementioned materials or unplasticized Polyvinal Chloride. Polyvinal Chloride pipe and fittings shall have a standard dimension ratio of 26, a pressure safety factor of 2.8 to 1 and shall bear the National Sanitation Foundation seal for potable water pipe. 3. Service pipe shall be constructed of Type K copper tubing or plasticized Polyethylene meeting the requirements set forth in Product Standard I1-691, with a standard dimension ratio of 7`and shall bear the National Sanitation Foundation seal for potable water pipe." -2 SECTION 4: That Section XII A of the Subdivision Improvement Regulations adopted by Ordinance No. 71-23 of the City of Tamarac is hereby amended to read as follows: "SECTION XII - 'As Built' Drawings ^ A.
