MISSION STATEMENT

The mission of Charles County Government is to provide our citizens the highest quality service possible in a timely, efficient, and a courteous manner. To achieve this goal, government must be operated in an open and accessible atmosphere, be based on comprehensive long and short term planning, and have an appropriate managerial organization tempered by fiscal responsibility.

OUR VISION

Charles County is a place where all people thrive and businesses grow and prosper;

where the preservation of our heritage and environment is paramount;

where government services to its citizens are provided at the highest level of excellence;

and where the quality of life is the best in the nation.

INTRODUCTION

This package is designed to assist developers and engineers through the permitting process and in the preparation of plans for submissions to Charles County. Well-prepared applications, reports and plans will require minimal revisions, thereby expediting the review and approval process.

These guidelines are the minimum requirements for submission of plans to Charles County. They have been extracted from the Charles County Road Ordinance, Grading Ordinance, Stormwater Management Ordinance, Storm Drainage Ordinance, Floodplain Management Ordinance, the Water and Sewer Ordinance, the Standard Detail Manual (Detail Manual) and the Charles County Standards and Specifications for Construction Manual (Specification Manual) and the department’s policy and procedures. These guidelines are not intended to replace the County ordinances or manuals. This document has been incorporated by reference in various Charles County ordinances thus making all requirements found in this document regulatory. Charles County requires that all developers and engineers obtain and thoroughly review all ordinances, codes, manuals and any other materials required for design and construction of projects within Charles County.

All of the referenced material can be found on the County’s website at www.charlescountymd.gov.

Close adherence to these guidelines along with a working knowledge of the County ordinances, design manuals, construction manuals and procedures will produce uniform, clear, and concise plans that are easily reviewed and easily read and interpreted by field personnel. Plans not meeting the minimum standards established in this document may be rejected.

The Codes, Permits & Inspection Services Division (CPIS) works closely with developers and engineers during all phases of development, from plan review through inspection and project close out to assure our mutual goal of quality development of Charles County.

Any person applying for a Development Services Permit (DS Permit) and/or doing related work must purchase a Charles County Standard Detail Manual and a Standard and Specifications for Construction Manual.
