(q) “Forested slopes” means an area meeting the definition of forest and growing on an area with a slope of 25 percent or more and covering an area of at least 10,000 square feet.

(r) “High density residential areas” means areas zoned for densities greater than 1 dwelling unit per acre, including both existing and planned development and their associated infrastructure, such as roads, utilities, and water and sewer service.

(s) “Institutional development area” includes schools, colleges and universities, military installations, transportation facilities, utility and sewer projects, government offices and facilities, golf courses, recreation areas, parks, and cemeteries.

(t) “Intermittent stream” means a stream in which surface water is absent during a portion of the year as shown on the most recent 7.5 minute topographic quadrangle published by the United States Geologic Survey as confirmed by field verification.

(u) “Linear project” means a project whose configuration is elongated with nearly parallel sides and used to transport a utility product or public service not otherwise contained in an application for subdivision, such as electricity, gas, water, sewer, communications, trains, and vehicles. Linear projects may traverse fee simple properties through defined boundaries or through easement rights.

(v) “Local forest conservation program” means a program developed and implemented pursuant to § 5-1603 of this subtitle.

(w) “Medium density residential areas” means areas zoned for densities greater than 1 dwelling unit per 5 acres and less than or equal to 1 dwelling unit per acre, including both existing and planned development and their associated infrastructure, such as roads, utilities, and water and sewer service.

(x) “Mixed use development” means a single, relatively high density development project, usually commercial in nature, which includes 2 or more types of uses.

(y) “Natural regeneration” means the natural establishment of trees and other vegetation with at least 400 woody, free-to-grow seedlings per acre, which are capable of reaching a height of at least 20 feet at maturity.

(z) “Net tract area” means:

(1) Except in agriculture and resource areas or linear project areas, the total area of a site, including both forested and nonforested areas, to the nearest one-tenth acre reduced by that area where forest clearing is restricted by another local ordinance or program;

(2) In agriculture and resource areas, the portion of the total tract for which land use will be changed or will no longer be used for primarily agricultural activities reduced by that area where forest clearing is restricted by another local ordinance or program; and

(3) For a linear project:

(i) The area of a right-of-way width, new access roads and storage; or

(ii) The limits of disturbance as shown on an application for sediment and erosion control approval or in a capital improvements program project description.

(aa) (1) “Nontidal wetland” means an area that is inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal conditions does support, a prevalence of vegetation typically adapted for life in saturated soil conditions, commonly known as hydrophytic vegetation.

(2) The determination of whether an area is considered a nontidal wetland shall be made in accordance with the publication known as the “Federal Manual for Identifying and Delineating Jurisdictional Wetlands”, published in 1989 and as may be amended and interpreted by the U.S. Environmental Protection Agency.
