The project aims to construct a "Sustainable Trail Design" utilizing natural materials primarily sourced on-site, adhering to sustainable trail design practices. Water management, under this design, occurs incrementally through trail contours, dips, and cross slopes. Proposed trail enhancements follow natural trail design and construction techniques, utilizing rock and soil from the site for recontouring. Steeper slopes will feature naturally shaped switchbacks anchored and edged with a combination of large, introduced rock and native rock found on site. The proposed stormwater infrastructure is integrated into the trail itself, treating each segment as a mini-watershed. Outsloped trails prevent water accumulation and erosion by gradually moving water from the footpath, thereby avoiding volume accumulation that leads to erosion. The project involves reforming trails to incorporate water control features like grade reversals, spillways, and out slopes. Details on how and where to install water features are provided within this solicitation as prescriptions. Heavy machinery operation experience in urban settings is necessary for this project. Expertise in implementing Sustainable Trail Design using specialized heavy equipment is required. Vendor Solicitation Requirements • Vendor is required to be a qualified professional sustainable heavy equipment trail builder. • Vendor must provide proof of formal certification in implementing sustainable trail and/or road design. • Vendor will have to independently determine the best way to implement sustainable trail improvements based on site conditions including topography, slope, soil and vegetation.
