What lies beneath Glenbury, Mars, and Marlowe Streets?

These neighborhoods was built over a century ago and include the following infrastructure:

• 105-109 year-old watermain and sewer mains
• Water flow to fire hydrants is too low, which creates a potential safety hazard
• Lead pipes bring water from the watermain in the street to homes, which is a potential water quality hazard
• Its been at least 11 to 15 years since the streets were resurfaced
• In comparison, new sewers and watermains last 50 years and newly resurfaced streets last 9 to 12 years.
