  • 5 | Infrastructure
    5 | INFRASTRUCTURE Infrastructure Policies POLICY 1: Invest first in infrastructure that supports the preferred scenario POLICY 2: Consider long-term operational costs when setting priorities among new capital projects POLICY 3: Seek funding from other entities whenever possible POLICY 4: Work with Lancaster ISD, Cedar Valley College, and other educational institutions to ensure that the “learning infrastructure” is in place Introduction Utilities and infrastructure are a critical piece of the foun- dation and operations of a city and can include water and wastewater systems, storm drainage systems, solid waste disposal, electric service, gas service, cable, fiber optics, and telephone service. The location, condition, and accessibility of these features can greatly affect daily operations, con- struction timelines, and funding capabilities. Understanding the system’s existing conditions is essential to planning for future development. Utilities and infrastructure can act as an indicator of a city’s ‘growing pains’ - meaning the per- formance of a system under pressure can show where the infrastructure needs to adapt, expand, or be replaced to accommodate growth. Figure 5.01 - Elevated Storage Tanks The City of Lancaster Public Works Department maintains a Street Division and Water Utilities Division. The Street Divi- sion services and repairs the existing streets and sidewalks, and are responsible for traffic signals, street sweeping, crack sealing, and storm water drainage. The Water Utilities Division is responsible for pumping and maintaining quality water, the distribution of water, and repairs and improvements to both the water and sewer system. 48 October 2016 Infrastructure | 5 Water System The City of Lancaster purchases water from Dallas Water Utilities (DWU).
