Significantly mitigate the frequency, magnitude and duration of sewer flooding and basement backups in the Northeast Boundary drainage area Control CSO discharges to the Anacostia River,

significantly improving water quality Minimize the nuisance and economic costs associated

with flooding Reduce risks to human health Greatly reduce the discharge of untreated wastewater

Accelerate Construction Minimize Impacts Maintain Quality Of Life• Contract milestones• Advanced utility relocations• Collaboration process for

tunnel construction – select best value (mitigation key differentiator between Contractors)

• Incentive milestones for utility relocations

• Acquire permits in advance of procuring Contractor

• DDOT Approved Traffic Study• Commuter Outreach Plan

(radio, social media, print, television)

• Off-peak hauling• Compact construction sites• Maintain access/services• Extensive coordination with

NEBT Outreach Efforts and Agency Coordination – Lavar Youmans

17

Since 2014 DC Water has conducted 61 meetings to inform residents and stakeholders about the upcoming NEBT project. 2 Environmental Assessment Meetings 5 Meetings with City Council Members 13 ANC Meetings 14 Block Meetings at the Construction Sites 22 Community Association and Church Meetings 5 Meetings with Business Associations

DC Water Outreach has visited each site to knock on doors and discuss the project with residents individually.

DC Water has analyzed potential impacts due to construction and coordinated appropriate mitigation requirements with: DDOT – Traffic, Pedestrian and Bicycle Impacts WMATA – Transit Impacts DOEE – Environmental Impacts FEMS – Fire and Emergency Services

Community Concerns –Colin Lavassar, Stephen Njoloma, Christopher Gerber, Lavar Youmans

Division J – Instrumentation and Monitoring• Construction may cause the ground to move. • There is a monitoring program to measure and document movements.

Instruments will be installed:• In the ground around each excavation.• In the ground above the tunnels and adits.• On private buildings adjacent to the tunnel alignment and at each

construction site. Instrumentation data is routinely reviewed by engineers from the

Contractor and DC Water. Action and Maximum Levels are set for each instrument to reduce

potential impacts to adjacent structures. A Right of Entry between DC Water and the Owner is required for survey

targets to be installed and monitored on private property. • Survey targets will only be placed on the exterior of structures.• Survey targets will be measured daily when excavation occurs nearby.

Community Concerns Ground Movement due to Construction

20

Community Concerns Pre-Construction Surveys Surveys are snapshots in time to document the condition of the building or

structure before and after the proposed construction.

In the event that claims are made for damages caused by construction activities. The Pre and Post Surveys can be compared side by side to confirm if claimed damages have occurred.

Survey information collected includes high-definition photos are taken along with a detailed narrated high definition video.

The pre-construction survey is typically complemented with the installation of optical crack gages on existing cracks and relevant instrumentation for monitoring settlement and vibrations during construction.

DC Water is currently performing free pre-construction surveys to eligible properties, i.e. properties adjacent to construction areas. Free post-construction surveys will be offered to property owners that participate in the preconstruction process.

21

Owner reports damage to theNortheast Boundary Tunnelteam using the project hotline

1 (800) 436- 8534

Project team schedules an inspection to gather information. The project submits a “Notice of Occurrence” form to ESIS, DC Water’s insurance company.

A claim number is generated and an ESIS adjuster schedules an inspection with the property owner.

If the ESIS adjuster determines the Design Builder is responsible for the damage, the property owner shall arrange for the necessary repairs

The ESIS adjuster will reimburse the owner accordingly and obtain the appropriate release

Public Outreach Continues Throughout the Cycle of Construction DC Water is interested in attending future ANC and Civic Association meetingsto discuss the NEBT. Ideally, DC Water will provide a brief, 20 minutepresentation on the project.

The NEBT Outreach Team understands that building and maintaining strong relationships is an integral part of executing asuccessful project that maintains public support. One of our major objectives is to remind the public of the NEBT benefits,and explain efforts that are being put in place to mitigate construction impacts and quality of life. The areas of focus bulletedbelow assist in creating an opportunity to adequately form, build and maintain relationships with the communities surroundingthe NEBT Construction Staging Areas (CSAs).

• 24/7 Hotline• Tunnel Forums• Website Updates• Email Updates • List Serve Updates • Traffic Advisory • Pre- Post-Construction Surveys• Webinars• Social Media• ANC Meetings • Mailings

• Project Information • Sheets • Mapping Tools • Council Member Meetings • Community Meetings/Events • Business Meetings • Block Meetings• Door Hangers• Handouts • Targeted Robo Calls
