Sewers and Smart Growth: Challenges, Opportunities and Strategies- Case Study Maps

Scenario 1- Dense Residential Development

Mapping Scenario 1 depicts densely developed residential neighborhoods. In this type of area, existing residences were built decades ago and consist mainly of small, cottage-like homes. While there is little new construction in these neighborhoods, there are teardowns and remodeling projects that have enlarged existing homes. This scenario resembles many of the south-facing neighborhoods developed in the early to mid twentieth century. Because of the age of many septic systems, development density and proximity to wetlands and estuaries, many such neighborhoods will be among the first targeted for sewering. This scenario demonstrates the importance of the planning objective of ensuring that community character and natural resources are protected or enhanced. The maps depict parcels of less than 5000 s.f., parcels 5000-10,000 s.f., and parcels 10,000-15,000 s.f. in size.

Scenario 2- Mixed Use Commercial/ Multifamily Housing

Mapping Scenario 2 depicts designated town center where there is pre-existing commercial development and a mixed-use environment with multi-family housing. Additional commercial growth may or may not be desired. There may be a considerable amount of additional development potential through development of vacant parcels and build out of underdeveloped parcels. The area may include residences on commercially zoned land, and may be surrounded on either side by residential neighborhoods. This scenario demonstrates the importance of the objective of ensuring that limited sewer capacity is allocated to areas and uses that support broader community planning goals. Scenario 2 maps are adapted from the 2008 Regional Policy Plan which shows economic centers and villages that could experience some of the characteristics described in scenario 2. Note that not all towns identified economic centers within their borders, but more such areas could exist.

Scenario 3- Open Space Planning

Mapping Scenario 3 depicts large undeveloped areas on Cape Cod. This scenario describes areas that sewer lines may need to pass through to reach areas described in either scenario 1 or 2, or to extend between them. The presence of sewers will increase the prospect of residential expansion or further subdivision, possibly under a 40B Comprehensive Permit. However, denser residential development in these areas may not be consistent with community planning objectives and or planned wastewater treatment capacity. This scenario demonstrates the importance of the planning objectives of managing growth within entire watersheds and not just sewered portions to ensure that TMDLs are met and are not exceeded; and Ensuring that community character and natural resources are protected or enhanced. Scenario 3 maps show the rough distribution of large (10 or more acres) parcels that are undeveloped or currently used for recreation. Many of these areas are within Zones of Contribution to Public Drinking Water Supplies (Zone 2s.) Title 5 limitations on development in Zone 2s would not apply if these areas are sewered, which could increase development potential.
