Allow for sufficient grow in period within the individual field closure that play can resume on time.

5 Multi-flow Under Drains This work shall consist of providing and placing a drainage system comprised of a geo-composite, prefabricated, water collection system (collection system) and the associated water transport system (transport pipe). The drainage system shall be installed in accordance with these specifications and in close conformity with the locations and dimensions as shown on the plans.

6 Trenching and Backfill Requirements The amount of trench excavated at any time shall not exceed the amount of drain that can be set and backfilled completely in one working day. The trench shall be 4 inches wide and 20” deep as specified in the plans. All excavated material shall be removed and hauled offsite for proper disposal. At no point shall the excavated material be used as backfill or any other purpose on the project unless approved by the City. The trench shall be backfilled with clean very coarse sand, Ortona Wellpoint sand or an alternate selected by the City. The contractor shall supply the City with specifications, source and a sample of the very coarse sand to ensure it meets the specifications.

7 Trenching and Backfill Requirements

8 Fittings Requirements Fittings shall be installed in accordance with the manufacturer's recommendations. The fittings used with the collection system shall be of a "snap together" design. In no case shall any product be joined without the use of the manufacturer's connector designed specifically for the materials specified.

9 Drainage connections The contractor shall submit a proposal on how the discharge lines will tie into the existing drainage system (catch basin) for review and approval by the City. All tie in shall be water tight.

10 Sod Requirements Once the trenches have been successfully backfilled with the required very coarse sand to proper grade, the trench must be restored with sand grown Tifway 419 Bermuda sod. The sod shall be cut and placed to proper size and grade to cover the trench and be level with the existing turf. The sod shall be supplied by a local grower and certified as Tifway 419 Bermuda and grown in coarse sand; not muck, clay or any other nonporous soil. The Tifway 419 Bermuda grass shall be fully established and ready for field play by the timelines set forth for each field subject to this project.
