Introduction and Background

Project History

• 2010-2011
• Summit County Department of Sanitary Sewer Services:
• Southwest Summit County Wastewater Study (Nov. 2010)
• Southwest Summit County Sanitary Sewer Master Plan (Dec. 2010)
• Southwest Summit County Wastewater Action Plan (Oct. 2011)
• “Hot Spot” Areas Delineated
• Analyzed Gravity Sewer vs. Vacuum Sewers
• Vacuum Sewers - $3.95 Million Assessment Cost
• 2014
• Design for Vacuum sewer is mostly completed
• Public meeting presents the Construction Estimate at $8.06 Million
• 2015
• Village Interviews firms and hires OHM
• Attended SCEIG to review funding options
• Decision made to work cooperatively with the County to find

a fair & equitable solution

• 2016
• Began re-engagement with 5 public meetings

throughout the year

• Reviewed alternative sanitary sewer designs
• Reviewed alternate assessment methods
• Discussed findings with the Village, DSSS, and citizens
• 2017
• Negotiated with Summit County DSSS to finalize

assessment method and discuss DSSS participation

• NOW
• Village & County Councils: Legislation to Proceed

Information Investigation and Preliminary Analysis

Service Areas Selection

• Service Areas were

divided based on many factors:

• Geography (Land

features, Hills and Valleys, etc.)

• Land Use (i.e. future

development)

• Natural Divides (e.g.

River, Railroad, etc.)

• Project Priority Areas

(i.e. phases)

• Settled on 22

Gravity

• Expensive
• Topography Issues
• Deep Pipe (increased

disturbance)

• Need for lift stations
• Still need Low Pressure in

some areas

• Future Development
• Upsizing now might not

meet existing requirements (i.e. pipe velocity)

• Extra cost for upsizing that

may not be needed

STEP

• County does not want to

maintain the system

• Filter Cleaning
• Septic Tank Pumping
• Pump Replacement
• Cleaning filter is not

environmentally friendly

• Some people may require

additional pumping from the house to the R/W.

• Extra storage capacity is

not as important on well water systems

Vacuum Sewers

Pros

• Already Designed
• Completely maintained

by the County

• Continues working

during power outage

• Don’t pay for electrical
• Vacuum station can be

split and moved away from downtown

Cons

• Higher Construction

Cost

• Must be installed at

right-of-way

• May require pumping

from house

• Higher Sewer Rates

Low Pressure Sewer

Pros

• Can be located

anywhere on the Property

• Cheaper Construction

Cost

• Lower Sewer Rates
• No need for utility

stations in town

Cons

• Will need to pay for

redesign

• Existing Design

Modification

• All equipment

maintained by the homeowner

• Pump (5-10 yrs)
• Tank (30+ yrs)
• Electrical Panel
• Will not work without

power

ESTIMATED 20 YEAR COST

• 1. All pumps run 1/2 hour per day @ $0.10 per kWh
• 2. Vacuum laterals cost more due to added length needed to run lateral to the intersection of the property line and R/W.
• 3. Gravity Laterals cost more due to increased lateral diameter.
• 4. Grinder Pumps are 2 HP, $250, and 5 yr lifespan (first pump included in assessment).

CHOOSING THE RIGHT ASSESSMENT FOR CLINTON

• What makes a good assessment?
• Is it fair?
• Ensure that everyone being assessed is pay the proper share of

their project.

• Is it defendable?
• The method should be able to stand up in court.
• Does it account for unusual circumstances?
• People with unique properties (e.g. flag lots, shared parcels,

HOA ownership, etc.) should pay a fair portion of the assessment.

• Does it account for future development?
• People building after sewer construction should still pay for

their portion of the project.

THE CHALLENGES…

• Clinton has VERY unique and diverse property
• wnership.
• Flag Lots
• Lots of area, very little frontage
• Shallow Lots
• Lots of frontage, very little area
• Paper Streets
• Very small parcels (many are shared by one home)
• Many parcels are unlikely to develop
• Luna Lake
• One Parcel, many houses, very little frontage

The Original Assessment

• Based and weighted on 5 criteria
• Frontage (5%)
• Area (5%)
• Land Value (25%)
• Parcel Connection (60%)
• Zoning (5%)
• Vacant lots were assessed as if they were

developed

Method Analysis

• Chose a small representative group of properties
• Ran multiple scenarios to see change across

properties

• Fair distribution was more significant than actual cost
• 4 Scenarios were run and modified
• Modified Summit County Assessment (land value and

zoning) removed

• Stark County Codified Ordinance
• Stark County modified for acreage instead of frontage
• Land Value Appreciation with connection

Recommendations

• A land value based approach appears to work best
• Does not single out unique properties
• Frontage/acreage doesn’t matter
• Vacant land is still accounted for (through value

appreciation) but not charged extra for a connection they may never get

• Future development can be incorporated into Connection Cost

(i.e. tap-in fees)

• Majority of cost is in the connection

Challenges

• Estimating property appreciation
• May need to hire appraiser (defendable)
• County must assume a portion of upfront cost in
• rder to make future tap-in fees balance over time
• A good compromise (residents can get a discount and

the county can return on investment)

• Clinton must estimate future growth over the next 20

years to a confident degree of accuracy

• Actual numbers have yet to be negotiated with the

county
