Abstract:

This report explains the process involved when proceeding from a wetland mitigation design concept to a fill engineering package that is suitable for public bid and advertisement The information provided is geared toward educating nonengineering professionals engaged in developing wetland mitigation specifications The biological foundations for the various elements are first presented, followed by full guideline specifications. The vegetation specifications address site preparation, plant material acquisition, transport, handling, and storage of seeds, herbs, and saplings, planting methods for various stock types, different seeding methods, tiring of planting in conjunction with seasonal variations, hydrological considerations such as tidal cycle, water level and rainfall patterns, equipment access and type, protection measures for herbivory, inundation and vandalism, fertilization and amendrnent application, soil-nutrient testing, substrate handling, trppsport, and storage and minimization of impacts on existing wetland resources. The subgrade specifications target construction methods and equipment, soil-material testing, and performance. The other soil-related specifications quarantine and safeguard existing resources such as friable surface soils and wetland topsoils that can be used to seed a site.
