This document is a detailed seeding specification section (Section 02936) for the Bridgeport WPCA (Water Pollution Control Authority) project, covering comprehensive guidelines for lawn and ground cover establishment. The specification outlines precise requirements for seeding, including two primary seed blends: Type I for lawn areas (consisting of 25% NK 200 Perennial Rye Grass, 25% Kentucky Bluegrass, and 50% Pennlawn Red Fescue) and Type II for temporary seeding (80% F-31 Tall Fescue and 20% Annual Rye Grass). Seeding is prescribed for spring (March 15 to June 15) and fall (August 15 to October 15) periods, with specific instructions for mechanical and hydro-seeding methods, soil preparation, fertilization, and mulching techniques.

The specification provides extensive details on material requirements, including granular non-burning fertilizer with specific nitrogen, phosphoric acid, and potash ratios, ground limestone specifications, and acceptable mulch materials like straw and wood cellulose fiber. Maintenance requirements are comprehensive, mandating a minimum 60-day maintenance period after seeding, with provisions for watering, spot weeding, mowing, and re-seeding until a uniform, healthy grass stand is established. The document emphasizes precise application techniques, such as incorporating limestone and fertilizer to a three-inch soil depth, using rotary or drop seed distributors, and applying straw mulch at specified rates, with special considerations for slopes and erosion control.
