The intent of the plan is to direct growth to existing population centers, protect our water supply and ensure that it is adequate, protect our agricultural, heritage and natural resources, maintain adequate and appropriate community facilities for our changing population, improve transportation in the County through safety measures, growth planning and offering public and alternative modes of travel, improve economic development and employment opportunities, and encourage redevelopment of existing housing and facilitate affordable housing. This comprehensive plan is important to ensuring that Caroline County is prepared for future growth in the County and its municipalities. With as many as 9,400 new County residents by 2030, the County is anticipating a major shift in the average age of the population. The largest age groups in the County are 24 -34, 35-44 and 45-54, all of which will be in the over 50 grouping by the year 2030 and this increase should be expected to have an impact on the types of services an amenities the County provides within the next 10 years. Additionally, the County is continuing to see increases in its Hispanic population which requires a different set of public services geared towards helping this population integrate more effectively into our community. Land Use This plan lays out a slight but very significant shift in thought from previous plans regarding where growth should occur in the County and how to direct growth to targeted areas. This plan proposes to review the R-1 “Residential” zoning district to determine what other zoning districts might be more appropriate and compatible with the visions of the Plan. Caroline County will continue to focus growth to the incorporated municipalities where services are more readily available. The County proposes to expand the use of its transferable development right (TDR) program in order to further protect the unincorporated areas of the County from unwanted sprawl that in turn increases the cost of providing services to County residents. Additionally, the County would like to see municipalities and their growth areas become the County’s TDR receiving areas where appropriate. The County is moving away from the idea of greenbelts and beginning to look at the entire R zoning district as a growth boundary. Water Resources The water resources element aims to identify drinking water and other water resources adequate for the needs of existing and future development discussed in the land use plan Caroline County Comprehensive Plan 5 ADOPTED April 6, 2010 and to identify suitable strategies for nutrient reduction to reduce our negative impacts on our water resources. Water quantity in Caroline County is generally considered good; however the long-term sustainability of our water resources, especially in an agricultural community, is a concern and continues to be researched by State and private entities. To address the sustainability of our water resources the County plans to work with stakeholder agencies to receive all data relative to the County’s current and future water needs, as it becomes available, and develop appropriate groundwater management strategies. To address the County’s pollution of waterways, the County has proposed strategies to reduce nutrient loads that target both the residential and agricultural communities. Resource Conservation The resource conservation chapter addresses natural, agricultural and heritage resources. The goal of this element is to protect our natural and heritage resources, while maintaining an agricultural land base that will continue to support our farming community and agricultural economy. The intent of this chapter is to encourage adopting legislation that promotes best management practices when it comes to the protection and use of our natural environment, improving our TDR and agricultural land preservation programs, and preserving the county’s valuable historic sites and structures to encourage historical tourism in the County. Priority Preservation Area The priority preservation area element is new to the Comprehensive Plan and was added to aid the County in becoming a Certified County with the Maryland Agricultural Land Preservation Fund (MALPF) and Maryland Department of Planning. Being certified will increase the percentage of agricultural land transfer tax the County receives from 33 1/3 percent to 75 percent. These funds can be used for local matching funds with the MALPF program. The County’s priority preservation area encompasses 176,760 acres and includes all land in the unincorporated areas of the County that is not designated as a TDR receiving area, municipal growth area or priority funding area.
