SUBDIVISION STREET PAVEMENT (a) Street Cross Sections. M street pavement for street types designated as 93N112889.051.ak 10-29-93 021808 2 Residential, Marginal Access and/or Collector Streets shall be constructed as specified below: (1) Minimum cross section requirements for street improvements are: CLAY SOILS1 LOCAL STREET 1.5" Type A5 6" 8" RESIDENTIAL COI .I ,PCTOR Type B ESAL2 HMAC4 ('10 000) CALICHE BASE LIMED SUBGRADE 2" HMAC 25 6" CALICHE BASE 8" LIMED SUBGRADE NEIGHBORHOOD 2" COLLECTOR 8" Type B, 10" C-60 & C-70 HMAC 75 CALICHE BASE LIMED SUBGRADE SANDY SOIIS3 1.5" HMAC 6" SOIL CEMENT 2" HMAC 6" SOIL CEMENT 2" HMAC 8" SOIL CEMENT 1 For Clay Soils Only: Local and Residential Collector cross sections shall be constructed over a 12 -inch section of compacted raw subgrade to 90% Standard Proctor, from which the 8 -inch limed subgrade shall be scarified and constructed. Compaction of the raw subgrade is not applicable to the remaining cross sections provided the depth is sufficient such that the native soil is in its natural undisturbed density. 2Equivalent single axle loads. For Sandy Soils Only: Local and Residential Collector cross sections shall be constructed over a 12 -inch section of compacted raw subgrade to 90% Standard Proctor, from which the 6 -inch soil cement shall be scarified and constructed. Compaction of the raw subgrade is not applicable to the remaining cross sections provided the depth is sufficient that the native soil is in its natural undisturbed density. A single course surface treatment shall be used as a seal over the soil cement base. In the event of quick soil conditions a separate design subject to the approval of the Director of Engineering Services/City Engineer will be required. 4Hot mix asphaltic concrete. 5 Type cross sections per the Corpus Christi Urban Transportation Plan. 93HI32839.051.ak 10-29-93 COMMERCIAL 2" COLLECTOR 10" Type 12" C-60 & C-70 INDUSTRIAL COLLECTOR Type C-60 & C-70 93NH2889.051.ak 10-29-93 HMAC 150 CALICHE BASE LIMED SUBGRADE 2" HMAC 300 12" CALICHE BASE 12" LIMED SUBGRADE 2.5" HMAC 8" SOIL CEMENT 3" 8" HMAC SOIL CEMENT 3 (2) Six (6) inch curb "L" Section A 6 -inch "L" curb shall be used on all street improvements. (3) Support Under Curb and Gutter Section The base material and/or limed subgrade in the street pavement shall extend two (2') foot beyond the curb and gutter on all sections. (4) Staged Application of Surface Course on Local and Residential Collectors Only The Developer may elect to delay the application of the surface course provided the requirements for deferment and provision for security are met in compliance with Section V. Paragraph A. Subparagraph 3. The Developer must then apply a single course surface treatment over the base upon completion of street improvements and may delay the application of one and a half inch (1.5") HMAC for local streets or two inches (2") for residential collectors for a period not to exceed one year. (5) Deviations from Minimum Cross Sections Deviation from the minimum cross sections shall be based on actual soil tests and structural design of pavement by a licensed Professional Engineer using any of standard methods of pavement design. an alternate cross section shall be of equivalent strength to the minimum cross section and subject to review and approval by the City Engineer. 4 (b) City Participation Policy. The City will pay additional construction costs with regard to pavement thickness greater than those of a Residential Collector street cross section for Neighborhood Collectors and Commercial Collectors to the extent permitted by the Texas Local Government Code. §§ 212.071 et. seq. (c) Pavement Widths. Widths of paving for the various types of streets, including standard two (2) foot curb and gutter shall not be less than the following: Street Type Pavement Width Major Thoroughfares 60 feet Collectors 40 feet Minor, for apartments 40 feet Minor, for residences 28 feet Marginal Access 28 feet Pavement widths for business or industrial developments shall be established by the Planning Commission on the basis of the extent and character of the proposed development. (d) Laboratory Testing. All materials to be used in subdivision construction shall be subject to testing if warranted. The preponderance of testing to be performed in subdivisions is directly related to street construction and a series of laboratory tests normally associated with road and street construction will be required in subdivisions, said tests being performed by an independent testing laboratory using qualified personnel. The testing laboratory shall be selected by the project Engineer for the street subject to approval by the City Engineer. The Developer will pay all testing fees for materials directly to said laboratory. Prior to acceptance, the Developer will submit an affidavit stating that all said testing fees have been paid the laboratory to the Director of Engineering Services/City Engineer. The Engineer shall notify the Director of Engineering Services/City Engineer at least one week prior to the contractor beginning construction and submit 93NH2889.051.ak 10-29-93 5 the name of the testing laboratory for approval. A testing lab authorization will be sent to the Engineer. It is assumed that the preponderance of testing required in the subdivision is that testing related directly to street and utility construction. For this reason the following ratio of testing is established. DENSITIES Raw Subgrade Curb/Gutter Base Material Stabilized Base Material Subbase -limed subgrade RATIO OF TESTING 1 per 200 Lin Ft of each lane/lift 1 per 200 Lin Ft curb and gutter 1 per 200 Lin Ft of each lane/lift 1 per 200 Lin Ft of each lane/lift Same as base requirements BACKFILL DENSITY CONTROL Utility Trench As determined by the Engineer Behind Curb and Gutter 1 per 200 Lin Ft curb and gutter PROCTORS Raw Subgrade Subbase Base Material Stabilized Base 1 per each type material 1 per 3000 Cu Yd of material 1 per 3000 Cu Yd 1 per 3000 Cu Yd LIME STABILIZED SUBGRADE Field Sieve Analysis 1 per 200 Lin Ft after final mixing Fades & Grim Test for percent lime required STABILIZING AGENT CERTIFICATION 1 for each type soil Receive Mill Certificate from Supplier on each Load (Stabilized Subgrade and Base) BASE QUALIFICATION TESTS Atterberg Limits 1 per 3000 Cu Yd and Gradation LA Abrasion 1 per 3000 Cu Yd CBR (Standard) 93M32889.051.ak 10-29-93 1 per 6000 Cu Yd Min 1 per subdivision HOT MIX ASPHALTIC CONCRETE Surface Course Design 1 per subdivision Base Course Design 1 per subdivision Lab sampling, lab 1 per subdivision molding, lab density, (1 per 500 tons -min) stability, maximum theoretical specific gravity and extraction Cored In -Place Density/ Air Voids,Thickness of compacted mix Minimum 2 per subdivision 1 per 1000 Lin Ft of street 6 CONCRETE Curb\gutter 1 set (3) per 500 Lin Ft Sidewalk 1 set (3) per 4,000 Sq Ft Inlets 1 set (3) per 6 inlets The above schedule is a minimum schedule for testing. Failures are not included. In the event of failures, additional tests will be required. If excessive rain occurs on a previously tested section, the City shall have the right to order re -tests as necessary. The City's representative on the job shall notify the testing lab when tests are to be taken. If the contractor cannot locate the City's representative within a reasonable period of time (2 hours), he may contact the Engineer, or his representative, who may then, after he has inspected the work, authorize the testing lab to take tests at the subdivision site. In the event neither the Engineer or the City's representative is available within two hours, the Contractor may order the lab test; provided, if it is necessary to re -test as a result of a Contractor ordered test, such re -testing shall be at the Contractor's expense. Except as otherwise provided above, it is the intent of the City that the Contractor not contact the lab for the purpose of requesting routine tests. The scope of testing any materials incorporated in subdivision construction is not necessarily limited to those tests outlined above. In the event of unusual conditions or factors which may give the City reason to question the quality of the materials in any portion of the subdivision, the City has the right to order such additional tests as are necessary at the Developer's expense. The City will consult with the Engineer on reasons for such additional tests before a testing lab will be asked to conduct such tests. All testing in accordance with these requirements shall be performed in accordance with the American Society of Testing -Materials (ASTM) latest revision, and/or as 93NH2889.051ak 10-29-93 7 elsewhere provided in approved plans and specifications for the subdivision. All subdivision test reports shall be certified by a licensed Professional Engineer (Texas License). The City shall be furnished with a minimum of two (2) copies of the testing reports. The Engineer shall provide to the testing laboratory, a set of plans and specifications as well as tabulation showing the estimate of quantities of material in the subdivision. (e) Lot Grading. Lot grading in subdivisions will be such that lots drain toward the street. Accordingly, all lots graded within subdivisions will be sloped such that a minimum grade of one percent (1%) exists from the front property lines to the rear of the lot. In the event it is not practical to drain lots to the street (rear to front), then an alternate drainage plan may be submitted for approval by the Director of Engineering Services/City Engineer. If drainage from adjacent property crosses such subdivision, drainage from adjacent property will be physically diverted to adequate drainage facilities or handled with the run-off from the subdivision itself. 2. CURB AND GUTTER Combined curb and gutters shall be constructed on each side of each street within the boundaries of each subdivision within the city limits and within the five (5) mile radius thereof, according to the following specifications: (a) For residential development, the curb and gutters shall be the City of Corpus Christi Standard six u few (4) inch felled curb of concrete, and shall have a minimum section twelve (12) ten (10) inches in depth at the back of the curb, six (6) inches in depth at the flow line of the gutter, seven (7) inches in depth in the outer edge of the gutter, and to be twenty-four (24) inches in width and may be varied in section to fit particular conditions involved_, (b) Along the side of any street abutting business, park, or school property, it shall be mandatory on the business, park, or school side of the street that the curb and gutter be of L -type City of Corpus Christi Standard, with a minimum height of six (6) inches, that driveways be designed as a "lay- ' 93NH2889.051.ak 10-29-93 8 c-urb-andgu a straight driveway section, and that the driveway width in the curb shall be in compliance with the Manual of Driveway Design and Construction Standards.
