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.

June 2012 12

All stormwater management designs shall be in accordance with the Charles County Stormwater Management Ordinance and the 2000 Maryland Stormwater Design Manual (and any supplements).

1. Review and Inspection Fees: The review fees are based on the County’s “Fees and Charges” schedule is required. This review fee shall be submitted with the initial submission of plan and the inspection fee shall be submitted prior to the issuance of a DS Permit. The fees are to be made payable to the Commissioners of Charles County. If the final review fee is less than the initial amount previously paid, a credit of the overpayment will be given toward the required inspection fee. Fees schedules are posted yearly on the County’s web site.

2. Bond Amount: The bond amount for stormwater management shall be 110% of the total estimated construction cost estimate. The construction cost estimate is based on unit prices established in the latest Unit Prices.

3. Cost Estimate: The construction cost estimate shall be based on the Unit Prices. Stormwater management construction cost estimates shall be separate from all other categories. Public facilities shall be broken out separate from the private facilities within the cost estimate.

4. Municipal National Pollutant Discharge Elimination System (NPDES) - Charles County is required to have an acceptable stormwater management program to remain in good standing in the Charles County’s Municipal National Pollutant Discharge Elimination System (NPDES) and may impose any stormwater management requirement from time to time to assure the County’s standing.

5. SWM Administrative Waivers - Project which received preliminary stormwater management plan approval prior to May 4, 2010 may request a SWM Administrative Waiver. Projects which receive a SWM Administrative Waiver may use the 2001 SWM Ordinance and the 2000 Maryland Stormwater Design Manual (without the supplement) as the basis for the design. SWM Administrative Waivers have sunset dates which would require a project submitted to receive final swm and sediment and erosion control approval by May 4, 2013 and final completion acceptance of the swm facilities and the associated sediment and erosion control facilities by May 4, 2017.

Project receiving a SWM Administrative Waiver must submit a copy of the approval letter with the plan submission.

6. Right-to-Discharge - If the project includes the increase of discharge from any point from a project the project developer may gain a Right-to-Discharge from the adjacent property owner after it has been determined that there is an adequate outfall. The Right-to-Discharge must be obtained prior to DS Permit approval and must be recorded in the Land Records of Charles County and must be shown on the plans.

7. Adequate Conveyance - Each project must adequately convey offsite runoff entering into the project via an adequate conveyance system. The development of the project cannot impede or backwater runoff onto the adjacent upstream properties beyond the pre-existing limits without gaining the rights through acceptable recorded documents. All documents must be recorded prior to DS Permit approval.

8. Location of Nonstructural, ESD or Micro Scale SWM Practices used in urban residential projects (excluding apartment complexes) shall be off the lots unless approved by the County in advance. These practices may be used in rural residential projects if it would be impracticable to place in an open space area. If an on-lot ESD practice or micro-scale bmp (excluding nonstructural practices for rooftop or non-rooftop disconnections) is provided to address a single residential lot then a SWM Inspection & Maintenance Agreement (Appendix 13) must be recorded prior to the issuance of the associated building permit.

9. I&M Agreements for Single Family Lots - The County may ask for recorded SWM I&M agreements for single family lots.

10. Inventory Sheets for Micro-Scale or ESD practices on Single Family Lots - The County may ask for inventory sheets for micro-scale or Nonstructural/ESD practices utilized on single family lots.

11. Bonding for Open SWM Channels - If a swm practice such as an open ditch serves a dual purpose (swm and drainage) the bonding for practice shall be included in the swm bond only.

12. Large Land Disturbance Activities such as mining projects are not exempt from having to address stormwater management. Stormwater management for these projects shall meet the swm requirements by designing swm using the target for ESD implementation to be “woods in good condition”. Once the mining is completed and if portions of the site will be returned to agricultural land management practices (cultivation of crops for sale) then the stormwater management plans may be revised to eliminate any stormwater management practice for those portions of the site returning to crop cultivation. The stormwater management for those portions of the site not returned to crop cultivation such as access roads must remain and be protected by permanent easements and or agreements.
