Known for its beauty and bounty, the Chesapeake Bay stretches nearly 200 miles from the mouth of the Susquehanna River to the ocean capes of the Atlantic, its tidal waters enriching the vibrant coastal communities of both Maryland and Virginia. Chesapeake Bay Explorer’s Guide is the perfect reference for visitors who want to know more about the things they see in their visit to the famous estuary, whether they are relaxing on a beach, paddling through a saltmarsh, or watching workboats duck beneath a drawbridge. Explore more than 14,415 miles of shoreline, myriad hiking trails, and scores of wildlife preserves nestled between resort towns and other attractions. This guide provides a concise history of how the Bay was formed, and brief entries with full-color images and easy-to-read descriptions of the flora, fauna, and man-made artifacts found in and around the Bay.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

This Low-Volume Roads Engineering Best Management Practices Field Guide is intended to provide an overview of the key planning, location, design, construction, and maintenance aspects of roads that can cause adverse environmental impacts and to list key ways to prevent those impacts. Best Management Practices are general techniques or design practices that, when applied and adapted to fit site-specific conditions, will prevent or reduce pollution and maintain water quality. BMPs for roads have been developed by many agencies since roads often have a major adverse impact on water quality, and most of those impacts are preventable with good engineering and management practices. Roads that are not well planned or located, not properly designed or constructed, not well maintained, or not made with durable materials often have negative effects on water quality and the environment.
