Input from the Oversight Committee Let’s see the numbers! – Is this a “build out” plan or a “management” plan for 2030? – How much should Cecil County grow in the future? – What densities do we need to support future growth? – What do these densities look like? – Do the towns support the framework of the scenarios? »If so, how do we implement? Let’s see the details! – How do we translate these general ideas to specific areas? – What about the towns? (COG meeting in September)
Revising the Scenarios Some concern that there was not enough difference between the scenarios, and that elements of the Growth Centers scenario were unrealistic (urban open space) Changed the Growth Corridor and Greenbelts scenarios to reflect input from the Oversight Committee Added Protected Lands
Changes to Greenbelt Scenario The Resource Lands in the Greenbelt Scenario are larger than anything we've previously shown. These expanded Resource Lands are drawn in a way that is intended to cover contiguous natural resources such as agriculture, forest, and environmentally sensitive areas, using the following information: Productive agricultural soils, as shown in the County's soil layer, cross-referenced with information provided by the APM subcommittee Sensitive areas, as described above, plus Forest Interior Dwelling Species and Sensitive Species Review Areas Developed or committed lands (including "pipeline" development, as well as some land zoned for development) was used to exclude areas from the Resource Lands category 12-digit watersheds, used as boundaries in some cases Roads, -used as boundaries in some cases
Land Use Categories Development: Areas that would be developed on land served by public water and sewer. Rural (olive green): New development would be permitted, at relatively low densities, with NO extension of public water and sewer (except for health emergencies). No change from before. Resource Land: Zoning would permit only very low density development (likely at 1/20 or less). The eventual PPA(s) would be drawn within these areas, although every piece of Resource Land would not necessarily fall within a PPA. Protected Land: Land that is already protected from development by virtue of having sensitive areas (floodplain/wetland), public or private ownership, or easement. This includes federal, state, and county owned land; MALPF, MET, ESLC, and other easements, etc. Employment Centers Mixed Development: Areas that would be developed as mixed-use centers of residential, commercial, employment, and institutional uses. The specific mix of use types has not been defined. Towns
Growth Corridor The provision of water and sewer infrastructure is seen as a key force driving change, as the lack of infrastructure has been a constraint to growth. The County’s agreement with Artesian allows the development of Elkton West and opens the easternmost section of the growth corridor The growth corridor between Perryville and Elkton would remain substantially intact. The Mineral Extraction District would be developed as a mixed-use residential area flanked by employment areas as envisioned by the property owners.
Growth Corridor Original
Greenbelts The Greenbelts scenario assumes that the people of Cecil County do not want to develop to the extent depicted in the Growth Corridor scenario. To constrain future growth, additional lands are designated for rural protection and the greenbelts are wider than in the Growth Corridor scenario Greenbelts of protected lands would be interspersed within the growth corridor. The extent of developed areas around the towns of Rising Sun, Chesapeake City, North East and the Stewart property would be decreased. More emphasis would be given to protecting agriculture and environmentally sensitive areas than in the other scenarios
Capacity Analysis Zoning District Current New Household Capacity BG0 BI0 BL0 DR14,919 M10 M20 MB0 MEA0 MH3,664 NAR3,985 OS0 RM12,742 RR2,298 SAR1,645 SR18,695 TR3,840 VR496 Municipalities5,228 Total67,512 Our planning assumption: Let’s start with the County’s capacity Based on current zoning, Cecil County has capacity for 67,512 additional housing units. Of this, 35,600 new housing units could be accommodated within the County’s Priority Funding Areas This is more than the 26,000 housing units identified in the 2030 projections.
Modeling the Scenarios Build-out versus 2030: – We are developing “build-out” scenarios so we can evaluate plausible futures for the County that assume a different land use pattern than we have today, and to consider areas like the Mineral Extraction Districts (which have no capacity assigned to them) Key question: What should the buildout number be? Our planning recommendation: Use Buildout plus an increment for the Mineral Extraction District

Preliminary CBA Factors
Choosing By Advantages The Fundamental Rule of Sound Decision-making: Decisions must be based on the importance of advantages. Choosing a Preferred Scenario
To illustrate the logic and simplicity of the CBA vocabulary, following are the CBA definitions of the terms attribute and advantage: An attribute is a characteristic, quality, or consequence of ONE alternative. An advantage is a beneficial difference between the attributes of TWO alternatives. Choosing by Advantages For this project, the scenarios are our alternatives.
Purpose of the CBA Group To give the Oversight Committee a role in determining the factors To learn and understand the CBA process To help the other members of the Oversight Committee understand and participate fully in the CBA workshop To review and refine the factors that we will use to evaluate the scenarios To identify the advantages of each attribute To generate a draft CBA matrix we will use in November

How Do We Organize the Factors? The Fundamental Rule of Sound Decision-making: Decisions must be based on the importance of advantages.
1. Development is concentrated in suitable areas 2. Sensitive areas are protected 3. In rural areas, growth is directed to existing population centers 4. Stewardship of the Chesapeake Bay and the land is a universal ethic 5. Conservation of resources, including a reduction in resource consumption, is practiced. 6. Economic growth is encouraged and regulatory mechanisms are streamlined 7. Adequate public facilities and infrastructure are available or planned 8. Funding mechanisms are addressed to achieve the visions. Maryland’s Eight Visions
Functions (from Visions) Concentrate Development in Suitable Areas Protect Sensitive Areas Direct Growth to Existing Population Centers Protect the Chesapeake Bay Conserve Resources and Reduce Resource Consumption Encourage Economic Growth Streamline Regulatory Mechanisms Assure that Public Facilities and Infrastructure are Adequate to Meet Future Needs Create Funding Mechanisms to Achieve the Visions
From Functions to Factors The Fundamental Rule of Sound Decision-making: Decisions must be based on the importance of advantages.
Growth Factors Concentrate New Development Inside the PFA/Growth Corridor Minimize the Number of Acres Developed Outside the PFA/Growth Corridor Minimize the Loss of Agricultural Land (acres) Assure that at least X percent of the County is in Rural Land Use Minimize the Loss of Forest Land (acres) Maximize the Percentage of Residential and Commercial Land Developed within the PFA/Growth Corridor Maximize Mixed Use Development within the PFA/Growth Corridor Maximize the Amount of Preserved Land in the County Concentrate Funding for Infrastructure Improvements within the Growth Corridor Minimize Impacts to Sensitive Areas (wetlands and riparian areas)
Travel Factors Minimize Total Lane Miles (principal arterials) Minimize Vehicle Miles Traveled (VMT) Minimize Vehicle Hours Traveled (VHT) Maximize Average Free Flow Speed Maximize Average Congested Speed Maximize the Percentage of People Who Can Walk or B ike to Work, Mass Transit and Other Destinations Minimize Travel Time to Destinations Ensure that Densities are Developed at Levels that Support Transit Create a Land Use Pattern that Supports Rail Transit
Water Resource Factors Minimize Impervious Surface (by watershed) Assure Adequate Public Drinking Water System Supply (by system) Minimize Point Source Nutrient Discharge (by watershed) Minimize Septic Systems Nutrient Load (by watershed) Assure Wastewater Treatment Plant Capacity Maximize Groundwater Recharge (by watershed) Minimize Stormwater Loads (by watershed) Improve Overall Water Quality (measured by discharge into the bay)
Other Factors Ensure that employment land served by public infrastructure is adequate to meet future demand (buildout employment) Ensure that the County Has the Capability to Implement the Plan Ensure that the Towns Have the Capability to Implement the Plan Measure impacts on public facilities and infrastructure, including schools and roads
