. . 4. There shall be no on-street parking for 20 feet from the edge of the painted white stripe closest to the intersection to the beginning of the painted crosswalk. This number shall be 30 feet when the intersection is signalized. 5. The first and last parking stalls in a line of on-street, curb-side parking spaces shall be 20 feet in length. All other interior stalls shall be 22-26 feet in length. 6. All on street parking markings and pavement striping shall conform to the TMUTCD. 6.04 PAVEMENT STRUCTURE REQUIREMENTS A. The pavement structure for all roadways outside of zoned industrial areas shall be designed based on soil data from the site, anticipated traffic volume, desired service life of the proposed pavement. The Professional Engineer of Record is responsible for ensuring that the pavement structure is designed to withstand the anticipated loads that are expected on the roadway. All roadways outside of zoned industrial areas shall be designed to adequately handle the design vehicle weight as outlined in City of La Porte Code of Ordinances Section 70-256. Such criteria shall be used to design the roadway when these data, in sum, recommend a pavement larger than the minimums below. B. Local residential streets shall be concrete and shall have a minimum thickness of 6 inches with No. 4 rebar spaced at 24 inches on-center or No. 3 rebar spaced at 18 inches on- center, and shall have a minimum of 6 inches of stabilized subgrade. C. All collector streets shall be concrete and shall have a minimum thickness of 7 inches with No.4 rebar spaced at 24 inches on-center, and shall have a minimum of 8 inches of stabilized subgrade. D. Major thoroughfares shall be concrete and shall have a minimum thickness of 8 inches with No.4 rebar spaced at 18 inches on-center, and shall have a minimum of 8 inches of stabilized subgrade. E. The subgrade shall be stabilized per the recommendations of the geotechnical engineer and shall be compacted to 95% Standard Proctor density. F. For concrete pavement within zoned industrial areas, the concrete pavement design and the calculation of its thickness shall be based on AASHTO design procedures for rigid pavements. G. The use of rebar dowels or the use of saw-cutting procedures to expose existing steel in concrete pavement is required to create a minimum of 12 inches of overlap of reinforcing steel when making a connection of a proposed concrete street to an existing concrete street or road. When the existing street has no exposed steel the following shall apply: I. Dowels should be No.4 rebar, 24 inches long, embedded 12 inches and epoxied. Applicable spacings shall be the same as the rebar spacings mentioned in these design criteria for the various concrete thicknesses. 2. If epoxied rebar dowels are impossible, saw-cut to a minimum depth of 2 inches and remove existing concrete to expose a minimum of 12 inches of longitudinal steel, in good condition, with an equivalent cross-sectional area of steel equal to the proposed pavement steel. Tie this exposed steel to the new steel in the proposed street and pour the new concrete over both. H. Dead-end streets and concrete paved streets designed to be extended in the future shall have paving headers and 15 inches of reinforcing steel exposed beyond the pavement (coated with asphalt and wrapped with burlap), or dowel type expansion joint for future pavement tie-in. I. Pavement extensions shall connect to the existing pavement with a pavement undercut and a minimum steel overlap of 12 inches. J. All concrete paving to be removed shall be removed to either an existing joint or a saw- cut joint. Sawed joints shall meet the requirements set out in this section. K.
