EXHIBIT C ADDENDUM TO ORDINANCE NO. 1975 - SPECIFICATIONS FOR OFF-STREET P&~ING LOT PAVD1ENT CONSTRUCTION 1. Sub-base. a). This item shall govern the placement and compaction of all materials obtained fran roadway, horrow, channel and structural excavation for utilization in the construction of off-street parking lots. b). Construction Methods. The area shall be cleared of stumps, brush, logs, rubbish, trees and shrubs, except trees and shrubs in certain areas designated by the Engineer for preservation. Those trees, shrubs and other landscape features specifically designated by the Engineer for preservation shall be carefully protected from abuse, marring and damage during construction. Trees and shrubs designated for preservation that must be pruned shall be trinmed as directed and all exposed cuts over Uvo inches (2") in diameter shall be treated with an approved asphaltic material. Areas required for parking lot construction shall be cleared and grubbed of all stumps and roots (except for designated trees and shrubs). Stump holes or other small excavations in the limits of the construction shall be back-filled with suitalbe material and thoroughly tamped by approved methods before crnmencing embankment construction. The surface of the ground, including plowed loosened ground or surface. roughened by small washes or otherwise shall œ restored by blading or other methods, and, where indicated on plans or required by L1ìe Engineer, the ground surface thus prepared shall be compacted by sprinkling and rolling. íl'Jhere indicated on plans or directed by the Engineer, the surface of hillsides to receive embankment shall be loosened by scarifying or plowing to a depth of not less than four ( 4) inches, or cut unto steps before embankment materials are placed. The embankment shall then be placed in layers, as herein- after specified, beginning at the low side in part width layers and increasing the widths as the embankment is raised. The material which has been loosened shall be recompacted simultaneously with the embankment material placed at the same elevation. Except as otherwise required by the plans, all parking lots shall be constructed in layers approximately parallel to the finished grade of the roadbed and unless otherwise specified each layer shall be so constructed as to provide a uniform slope of one-fourth (1/4) inch per foot. c). Earth fill - Earth fill shall be defined as that composed principally of material other than rock, and shall be constituted of accepted material from approved sources. Except as otherwise specified, earth embankIT£nt filling shall be constructed in successive layers for D1e full width of the individual parking lot cross-section and in such lengths as are best suited to the sprinkling and compaction methods utilized. Layers of embankment may be formed by utilizing equipnent which will spread the material as it is dumped, or they may be formed by being spread by blading or other acceptable methods from plies or windrows dumped from excavating or hauling equipnent in such amounts that materials is evenly distributed. Each layer of earth fill shall be uniform as to material, density and moisture content before beginning compaction. Where layers of unlike materials abut each other, each layer shall be featheredged for at least one hundred (100) feet or the material shall be so mixed as to prevent abrupt changes in the soil. No material placed in the embankment by dumping in a pile or windrow shall be incorporated in a layer in that position, but all such piles or windrows shall be moved by blading or similar methods. Compaction of embankments shall be obtained by the method hereinafter des- cribed as "Ordinary Compaction".
