11. Existing Regulations

16. Water Availability Analysis Put all of that information into a model Is there enough water?

17. Water Availability Analysis What happens if:  No precipitation to recharge the basin  Average precipitation  All platted lots are built out  All platted lots are built and there is no precipitation  All platted lots and all lots allowed by zoning are built  If build out is achieved and there is no precipitation

18. Water Availability Analysis Questions?

19. CMP Water Introduction The County does not provide any water or wastewater services. These services are provided by municipalities, Special Districts, and private companies. If water and/or wastewater service is unavailable, then water is provided by wells and wastewater is handled by Individual Sewage Disposal Systems owned and maintained by the property owner. Reservoirs are utilized by many water providers to store water until it is needed. Water rights, necessary to provide water, fill reservoirs, and drill wells, are governed by the State. Water quality is regulated by both state and federal agencies. The adequacy of water supplies is determined by the County.

20. Conifer Water Introduction There should be a balance between the availability of water and its uses to insure that water resources are not depleted. Water quantity, quality and sanitation are critical elements that should be considered when development is proposed for the area. Water is essential for almost all development and must be obtained by drilling wells on individual parcels or from a centralized water system. Sewage is treated either through individual sewage disposal systems (ISDS), also referred to as on-site wastewater treatment systems, through cluster systems or through a centralized sewer system. Proper sewage treatment is necessary to avoid contamination of wells, surface water, and ground water resources. Treated effluent water should be used to recharge the source ground water supply of the area served. Water quality also can be affected by soil erosion, animal waste, and sedimentation caused by human and natural processes. Legal erosion control/retention ponds or structures should be used to control storm water runoff.

21. CMP Water Goals Goals Protect the quality and quantity of water resources in the County. Ensure that New Development has appropriate water service and wastewater treatment. Manage the use of wells and Individual Sewage Disposal Systems (ISDSs) to ensure that the quantity and quality of water resources are sustained, and human health and the environment are protected.

22. Conifer Water Goal Goal Balance the availability of ground and surface water, water use, and ground water recharge with current and future development, to ensure that water resources are not over-allocated.

23. CMP Water Policies Outside Village Centers Inside Village Centers Service Levels Sanitation Community Plan Implementation

24. Goal & Policy Comparison

25. Policy Comparison Guidelines Not looking for identical language Looking for the same outcome Policies must be related to land use

Change to: New private centralized water and/or sewer systems should follow the policies under “Formation of New Special Districts.” In addition …

27. Conifer/285 Proposed Water Policies Existing: 298 gallons for 1 home on 5 acres Change to: 5 acre minimum lot size on well and septic

28. Conifer/285 Proposed Water Policies Existing: 90% recharge Change to: Recharge to same general basin

29. Other Policies Are there other Policies needed?  In current plan  New policies
