About this file

This document is a technical specification section (Section 32 90 00) for Planting, specifically related to the "Improve Sewer System and Water Loop" project in Marion, dated 07-01-16. The specification provides comprehensive details for landscape and planting work, including requirements for seed mixtures, soil preparation, hydroseeding, and erosion control.

Key technical specifications include using state-certified endophyte-enhanced grass seed with specific mixture compositions (25% Kentucky Bluegrass and 25% Perennial Ryegrass for sun and partial shade areas), hydroseeding at 260 pounds per acre, and implementing slope erosion control maintenance. The document outlines strict requirements for soil testing, fertilizer selection, and planting conditions, mandating that planting occur between March 1st and October 31st, with restrictions on soil and weather conditions. The specification emphasizes environmental considerations, such as using collected stormwater, avoiding chemical fertilizers, and protecting newly planted areas during construction.
