This data release includes the data used to generate histograms that compared total watershed pollutant removal efficiency (TWPRE) in the two study watersheds Crystal Rock (traditional watershed) and Tributary (Trib.) 104 low impact development (LID watershed) to determine if LID BMP design offered an improved water quality benefit. Input/calibrants data used in the model (Monte Carlo) are described in the manuscript as mentioned in the list below: -BMP Name and Type: references in the manuscript -BMP Connectivity: Proprietary (derived from Montgomery County GIS Data) -BMP Drainage Areas: Proprietary (derived from Montgomery County GIS Data) -BMP Efficiency Ranges: referenced in manuscript -Baseline Pollutant Loadings: referenced in manuscript Stormwater runoff and associated pollutants from urban areas in the Chesapeake Bay Watershed represent a serious impairment to local streams and downstream ecosystems, despite urbanized land comprising only 7% of the Bay watershed area. Excess nitrogen, phosphorus, and sediment affect local streams in the Bay watershed by causing problems ranging from eutrophication and toxic algal blooms to reduced oxygen levels and loss of biodiversity. Traditional management of urban stormwater has primarily focused on directing runoff away from developed areas as quickly as possible. More recently, stormwater best management practices (BMPs) have been implemented in a low impact development (LID) manner on the landscape to treat stormwater runoff closer to its source.The objective of this research was to use a modeling approach to compare total watershed pollutant removal efficiency (TWPRE) of two watersheds with differing spatial patterns of SW BMP design (traditional and LID), and determine if LID SW BMP design offered an improved water quality benefit.

This data was developed in response to citizens’ road maintenance requests from across the state as to whom to contact as the official maintenance authority - be it MDOT State Highway Administration, MDOT Transportation Authority, a county, or a municipality.MDOT SHA Website

This data release includes the data used to generate sewershed "bubble plots" that compared pollutant removal efficiency (PRE) in each sewershed in the two study watersheds Crystal Rock (traditional watershed) and Tributary (Trib.) 104 low impact development (LID watershed) to determine if LID BMP design offered an improved water quality benefit as compared on a sewershed basis.

Water bodies are defined as being any area of water, including streams, greater than 500 square feet in size; includes ponds, rivers and lakes. For more information, contact: GIS Manager Information Technology & Innovation (ITI) Montgomery County Planning Department, MNCPPC T: 301-650-5620

The County's Water and Sewer Plan assigns a water category and a sewer category to every property in the County. These service area categories serve two functions:They identify areas approved or planned for community water or sewer service and areas intended for service by individual (on-site) systemsThey identify a mechanism for staging community service for those areas planned for community service. The mechanism consists of the use of service area categories W-1 through W- 5 (for water) and S-1 through S-5 (for sewer).The Maryland Department of the Environment (MDE) requires the County to prepare a comprehensive update of the Water and Sewer Plan every three years. Between comprehensive updates, the County approves amendments to the plan (such as service area categories, new or revised policies, and technical information) through procedures described in Chapter 1 of the Plan. The County Executive, acting through the Department of Environmental Protection (DEP), prepares the Plan's comprehensive updates and also provides recommendations to the Council for action on proposed amendments. DEP, with the assistance of other agencies, develops some amendments, typically those that involve policy issues or category changes that affect groups of properties. Property owners also propose amendments, usually those involving category changes for single properties or larger tracts intended for subdivision of new lots. Under state law, the County Council is responsible for approving the plan and its amendments. MDE maintains an oversight authority over the County’s Water and Sewer Plan and its amendments. The agency administers regulations that each county must follow in the preparation of its comprehensive plan, and acts to approve, approve with modifications, or disapprove the Plan or any Plan amendment submitted by the County. As part of this process, MDE seeks guidance from the Maryland Department of Planning for consistency with local and State planning use goals, policies and objectives.For more information, contact: GIS Manager Information Technology & Innovation (ITI) Montgomery County Planning Department, MNCPPC T: 301-650-5620

Stormwater management facilities (SWMFAC) are structural best management practices that temporarily store or treat stormwater runoff to reduce flooding, remove pollutants, and provide other amenities.

This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.

A Site Plan is a detailed plan, required only in certain zones, that shows proposed development on a site in relation to immediately adjacent areas. It indicates roads, walks, parking areas, buildings, landscaping, open space, recreation facilities, lighting, etc. Site Plan review is required of all floating zones and of most overlay zones. It is also required in some zones when using optional method of development provisions. Further, certain parking facilities that fall under the provision of the off-street parking section of the Zoning Ordinance are also subject to Site Plan review.
