This law requires local jurisdictions to reduce the number of forested acres cleared when land is developed for residential, commercial or industrial use. Howard County’s Forest Conservation Program was implemented in 1993 to meet the mandates set forth in that act. To date, thousands of acres of forests across Howard County have been protected in perpetuity through the creation of hundreds of forest conservation easements. Although some of these are located on public land, many are located on private property. The easements require that the owners manage the forests to insure its long-term survival and function. The layer is attributed with project number, subdivision name, f-number, area ID, lot number, acres, plat reference, origin and coordinates. The Howard County Forest Conservation areas are of exact locations, as depicted by various polygons within Howard County Maryland.Forest_Conservation_EasementsfeaturesEPSG:2248-77.17965704231791 39.10688210972019-76.70403212170787 39.3683647367913general:GI_Forest_Interior_50acsForest Interior 50acsforest interior habitat of 50 acres or larger.

The Conservancy data was then altered to combine several classes representing different types of tree canopy into two classes designated “hard canopy” and “soft canopy,” relating to canopy over impervious and pervious surfaces, respectively. Then, a subset of “soft canopy” was created using the parameters of the Forest Conservation Act’s definition of forest, generating a data set of areas that are likely to be considered forest with respect to the Forest Conservation Act.

The Maryland Sustainable Communities Program is a place-based designation offering a comprehensive package of resources that support holistic strategies for community development, revitalization and sustainability. Howard County has worked with Maryland DHCD to designate certain areas of the county as Sustainable Communities including Ellicott City, North Laurel-Savage, and Long Reach Village.
Obtaining the sustainable community designation, which lasts five years, opens eligibility for state programs and resources, such as Neighborhood BusinessWorks, Community Legacy and the Strategic Demolition Fund. The designation also enhances competitiveness for state programs such as Maryland Bikeways.featuresStudyArea_Sustainable_Community_BoundaryEPSG:2248-76.87359451764964 39.10301273063376-76.7889964836412 39.278253205470655general:Study_NewBMPsStudy_NewBMPsfeaturesStudy_NewBMPsEPSG:2248-76.85086609783721 39.1291595660976-76.7984202110182 39.177889156542136general:Swimming_PoolsSwimming PoolsPolygons of in-ground swimming pool edge (not decks) captured as part the the 2022 planimetric update using 6 inch pixel orthophotography as the source.
