2nd Quarter Highlights

ON THE COVER: (Clockwise) Vinton Street Green Infrastructure, Adams Park Wetlands Improvement Project, Nicholas Street Phase 2 to 23rd and Grace, Spring Lake Park Landscaping and Leavenworth Lift Station.

• Saddle Creek Retention Treatment Basin (RTB) Early Soils Removal Project

neared completion. The purpose of this project is to prepare the site for

the Combined Sewer Overflow (CSO) control facility to be constructed in

the future for CSO 205 for the Saddle Creek Basin.

• Coordination efforts commenced for start-up activities for Leavenworth

Lift Station, Missouri River Wastewater Treatment Plant (MRWWTP)

Projects and South Interceptor Force Main (SIFM) North and South/Central

Segment Projects.

• Extensive efforts were completed to communicate with the contracting

community on the MRWWTP B2 Project, which resulted in a favorable

construction bid.

• Spring-fed water and rainfall runoff began to fill the lagoon at Spring Lake

Park, as originally designed.

• Construction issues were addressed and contractor continued work on

the MRWWTP Bank Stabilization.

• Gilmore Avenue Landscape Improvement Project construction was put

out for bid and the design work continued on the Fontenelle Lagoon

Improvement Project so that bidding could take place this summer.

ii Omaha Combined Sewer Overflow Control Program | Implementation Phase

CSO

Solutions

Goal 1:

Regulatory

Compliance.Meet specific regulatory requirements as identified by the EPA and NDEQ.

• Complete

implementation of

CSO solutions within

schedule identified.

• Reduce pollutant

discharge to the Missouri River

and Papillion Creek.

Goal 2:

Economic Affordability.Minimize cost impact to ratepayers by completing CSO control options within or under budget.

Goal 3:

Community Acceptance. Maintain continuous public dialogue, provide information and pursue opportunities for multiple benefits in CSO solutions.

The Program schedule, which began in 2006, is shown below. The final implementation is targeted for 2027. The Program is divided into two groups: major projects and sewer separation projects. Project implementation was selected based on its positive effect on water quality, supporting development, its priority in the construction sequence, and cost. The schedules were further coordinated to allow for concurrent construction. A list of projects by LTCP phase is located in the Appendix.

PROGRAMOVERVIEWIn order to comply with the

requirements of the Clean Water

Act, the United States Environmental

Protection Agency (EPA) Combined

Sewer Overflow (CSO) Control Policy

of 1994 and Administrative Consent

Order with the Nebraska Department

of Environmental Quality (NDEQ),

the City of Omaha developed a

Long Term Control Plan (LTCP)

that outlines the actions to control

overflows from its combined sewer

system. The purpose of the Omaha

CSO Control Program (Program)

Implementation Phase is to ensure

that CSO projects outlined in the City

of Omaha’s LTCP are cost effectively

designed, constructed, and placed

into operation by 2027.

CURRENT CSO PERMIT IS VALID THROUGH

OCTOBER 2020The CSO permit was approved by NDEQ in September 2015 with refined requirements that lower the City’s costs and in support of Omaha’s Program. The next required CSO permit renewal is October 2020.

Projects on Hold

Both the Saddle Creek

Retention Treatment Basin

System Projects were put

on hold this quarter due

to significantly increased

costs. These are under

evaluation to find more

cost-effective approaches

and additional information on potential

alternatives will be provided at a later date.

LEGISLATIVE ACTION IN SUPPORT OF THE PROGRAMThe City of Omaha is working with the Nebraska Department

of Natural Resources (NDNR) Grant Award Contract to finance

the construction of CSO projects and the water quality

improvements. Under this action NDNR will provide $2.9 million

in 2016 and approximately $1 million per year from 2017 through

2027. This agreement with NDNR for grant funds appeared

on the City Council agenda in June and July 2016 for the

Council’s approval.

Value Engineering (VE) efforts continue on the Saddle Creek RTB project to assess potential cost savings to the Combined Sewer Overflow (CSO) Program as well as providing benefit to the surrounding community. The outcome and recommendations from this VE effort is expected early fall 2016.

VALUE ENGINEERING TO

IMPLEMENT COST-EFFECTIVE

SOLUTIONS

Economic Affordability is the minimization of the cost impact to the ratepayers.

Construction costs have been contained as shown in the following metrics.

Goal 2: Economic Affordability

CURRENT & COMPLETED PROJECTCONSTRUCTION COSTS

RATEPAYER ASSISTANCEWhen the long term control plan (LTCP) was approved it marked the start of a ratepayer assistance plan to help low income and fixed income households with the rate increases necessary to fund the Program.

From April 2016 through June 2016, over $94,443 has been provided in assistance; to date $4.5 million has

been provided. Ratepayers are eligible if they receive Low Income Heat and Energy Assistance (LIHEAP) from their utility. This has kept administrative costs to a minimum and provided the maximum benefit to those who need it.

For assistance or to apply for Nebraska LIHEAP, call 800-383-4278.



Community Acceptance provides continuous open dialogue with the public along

with timely and accurate project information. The Program is also providing additional

neighborhood benefits, beyond the improved sewer system and water quality enhancements.

PUBLIC INFORMATION

The Combined Sewer Overflow (CSO) Program hosts a

public website and provides updates via Twitter including

up-to-date information to the ratepayers. A Contractor’s

Corner, which identifies upcoming bidding opportunities,

is also on the website.

ADDITIONAL PUBLIC BENEFITSIn addition to the over 56,000 feet of sewer pipe removed,

constructed and/or rehabilitated, the Program construction

projects have provided a total Community Enhancement

value of over $36 million, as identified below.

OUTREACH & STAKEHOLDER ENGAGEMENTInformation is regularly made available to the public

Adams Park outfall structure and wetlands near 36th and Bedford.

Adams Park Wetlands Improvement ProjectThis project consists of wetlands

designed to reduce Combined Sewer

Overflow (CSO) volumes, sewer

backups, improve water quality, and

provide a neighborhood amenity.

The existing combined sewer will be

converted into a sanitary sewer that

will provide sewer separation for the

sub-basin. The new storm sewers

will drain into a new wetland area in

Adams Park.

The Adams Park wetlands and

detention area is designed to provide

the maximum practical stormwater

storage to reduce the size of

future downstream facilities. The

wetlands consist of an area covering

approximately 14 acres, separated

by the park road. A low dam with

an emergency spillway is complete

on the north side of the park,

near Bedford Avenue, to provide

detention volume of up to 77 acre-

feet, which will detain the 100-year

storm event. The wetland facility is

designed to provide water quality

benefits and beautification elements.


PROJECT SPOTLIGHT

A separate construction contract

for the installation of trees and

landscape features included a

two year maintenance agreement

to ensure the plantings are well-

established before the project is

considered complete.

Additional information on this project can be found in the Appendix.
