Observations• Geographic, economic and jurisdictional diversity creates many
challenges
• History demonstrates interrelationship between Infrastructure and growth & development
• Recent growth has predominately occurred in the context of the hi i i f b i i i i d li i ihistoric infrastructure, bringing opportunities and limitations

• Other – land use regulations, cost of fuel, population growth
• Storage Reservoirs(66% f f fl(66% of surface flows occur late spring /early summer)
• Irrigation Canals
• Lateral Ditches
• Land Application
Potable Water SupplyRegulatory Jurisdiction
State Division of Water Resources• Water rights and well permits• Quantity or quality not addressed
La Plata County• Water quantity and quality• Water quantity and quality • Pre-approval stage only• No ongoing monitoring
CDPHE• Water quality for larger systems• Ongoing monitoring and reporting

permitted & completed
• At 2.3 persons/well, approx.25,000 residents served
• Well Cost ~ $8,000 - $15,000
Surface Water• Approx. 27,000 residents currently served• 14 total community systems• 6 systems (Durango, Bayfield, Ignacio, haulers) serve ~22,000• 8 non-municipal systems serve ~5,000

Water Critical Areas
Water Supply Constraints
• Well production at onset and over time
• Actual yield of water rights
• Availability of augmentation water
• Expense of hauling
• Lack of reliability for hauling
• Right-of-Way for centralized systems
• Capital costs of central systems
FIRE PROTECTIONWhat Needs Are Met?
• Safety
• Eliminate or reduce loss of property and life
• Pre-Disaster Hazard Mitigation Plans
Abili b i h i• Ability to obtain home insurance
Fire DistrictsFire ProtectionDistricts
Fire ProtectionDistricts
4 Districts
35 Stations
Pre-Disaster Hazard Mitigation Plans
Example: “La Plata County Community Wildfire Protection Plan”
• Protects existing i finfrastructure
• Raises residents awareness about fire mitigation
• Provides basis for receiving grants.
Fire Protection Constraints
• Greater than 5 road miles from station, high International Organization of Standards (ISO) rating high and insurance challenging (high or not achievable)
• Thus, larger subdivisions or commercial projects may need to construct stationsto construct stations
• Emergency and fire response service become weakened when dispersed
