Perry, Iowa [information]

A few facts about the communityTown of over 8,000 northwest of Des Moines in Dallas CountyAlong the Raccoon River Valley Trail North LoopFormer hub for the Chicago, Milwaukee & St. Paul Railroad Home to Historic Hotel Pattee, Historic Carnegie Library Museum + 50 National Register of Historic Places properties

Sustainability Study [grant]

Awarded an American Reinvestment and Recovery Act [ARRA] Sustainability Grant through Iowa Economic Development Authority [IEDA] in 2012

Conduct Inventory and Analysis to reduce energy use: Wastewater Treatment Facility Water Treatment Plant Street Lighting in the Downtown Cultural District Multi-Modal Transportation

Share the findings (and process) with interested member cities/residents of Common THREAD

Public meetings were held in select Common THREAD communities to share the process and results: August 14 – Perry August 14 – Perry [in English + Spanish] August 27 – Coon Rapids August 28 – Ogden August 29 – Huxley August 30 – Dallas Center



Sustainability isn’t just about technical feasibility, but also:• public

acceptance,• environmental

compatibility, and• economic viability


Waste Water Treatment Facility Treatment Process

Aeration basin blowers use the most energy at the facility o Equipment that takes care of the treatment processo All 4 are in use during peak treatment

Program blowers to operate more efficiently o Organic period is lower overnight and early morningo Stage dissolving oxygen concentration to a lower level to

require less blower operation


Water Treatment Plant pH and Nitrite control

Control of these two elements creates a more sustainable water supply

More consistent process/energy use Reduces maintenance and operation costs

Building Lighting Upgrade to energy efficient fixtures Reduce energy use & maintenance hours


Water Treatment Plant Distribution and Pump Operations

High Service pumps = most significant power use Current configuration has 4 pumps: 2 small + 2 large 2 small pumps were being used to fill tower

Use of 2 large pumps proved to be more energy efficiento Switching to larger pumps resulted in nearly $6,000 annual

savings,o and a roughly 26% reduction in energy consumption

Sustainability Study [grant]Downtown Cultural District Lighting Inventory existing lighting to establish energy use Focused on public right-of-way and public buildings

Inventory noted location, type and wattage

Baseline used to compare energy savings potential with energy efficient lighting

Calculated kWh use/yearo Assumed 20 year life energy costs

Implementation [results]

Iowa Energy Bank (IEB) Lighting Project City secured a low interest loan through IEDA/IEB in 2013 to replace

or retrofit lighting in the community over summer 2014 Waste Water Treatment Facility + Recycling Center Water Treatment Plant Perry Municipal Airport Public Works Shop Building McCreary Recreation Center Public Library Downtown Cultural District [8 blocks of street lighting]

City also worked with Alliant Energy to receive energy rebates for these improvements

Multi-Modal Transportation Deficiencies Deficiencies to the existing system include:

Lack of trail system in neighborhoods No connections from local roads and neighborhoods to the larger

regional trail system Dangerous crossings and corridors for pedestrians and cyclists Lack of connection to city parks and amenities Lack of connections within the community to larger employers

System Deficiencies Mapping


Develop Multi-Modal Transportation Plan Priorities Phasing Plan – may take years to implement Overall plan – shows the [big picture]

• Valuable guide in developing future Complete Streets• Valuable guide in seeking future funding

Priorities established based on safety, usage, connections to existing trails and amenities.• High, Medium, and Lower priorities were mapped

High Priorities Recommendations


Sidewalk and Trail Projects City updated Comprehensive Plan to include Multi-Modal network

developed for Sustainability Study [2013] City received a local grant [Bock Foundation] to extend the Iowa

Street Trail [2014] When complete will connect Raccoon River Valley Trail (RRVT) and

Dallas County Hospital Conducted I-WALK audit for Perry Elementary Schools [2014] Prepared TSIP (Traffic Safety Improvement Program) grant

application for 1st/Willis Ave. intersection [2014] Prepared REAP (Resource Enhancement and Protection) grant

application for Pattee Park Buffer/Trail Project [2014]

Momentum [previous success]

Sustainability Initiatives - City Hall LED Lighting Project

Lighting retrofit project removed o [465] 50 Watt halogen bulbs o [134] halogen flood lights

Replaced bulbs with a combination of 3.3W and 7.8W LED lights

City expects a 93% reduction in electricity use associated with interior lighting as a result of this project


Sustainability Initiatives - City Hall Roof Replacement

Energy-efficient roof replacement included use of R-30 or better insulation to reduce heating demand during cooler months


Sustainability Initiatives – Community Center HVAC Efficiency Upgrades

HVAC heating and cooling system upgrade Replaced the existing HVAC pneumatic control system

with a Direct Digital Control (DDC) system. City expects to see approximately:

o 35% reduction in annual kWho 24% reduction in annual therms


Sustainability Initiatives – WWTP & Recycling 50 kW Wind Turbine at Wastewater Treatment Plant

WWTP is one of the largest energy-demanding facilities City installed a 50 kW wind turbine to provide clean,

renewable energy and offset electric costs 5 kW Wind Turbine at Recycling Facility

Recycling Facility diverts 30% waste from landfill City installed a 5 kW wind turbine at its Recycling

Facility– Both turbines generate over 100,000 kWh of

electricity annually


Sustainability Efforts – Farmer’s Market Building 7 kW Solar Photovoltaic System

The City installed a 7 kW net-metered solar photovoltaic array Provides clean, renewable energy and offsets electric costs at:

o Farmer’s Market Buildingo Bike Coalition Buildingo Parks Maintenance Building

Funding + Resources [success] City Hall Lighting

• partnered with Aliant Energy on the top floor• Leveraged Federal Economic Recovery Act $ through former Iowa

Office of Economic Independence for remainder of the building

McCreary Community Center HVAC Improvements• Leveraged Federal Economic Recovery Act $ through former Iowa

Office of Economic Independence

Funding + Resources [success] 50 kW Wind Turbine

• City leveraged private sector investment that used lender financing with no guarantee by the City: $274,000 commitment

• Alternative Energy Revolving Loan Fund (AERLP): $137,000o 50% of purchase price at 0% interest for 15 years

• US Treasury Department reimbursement: $82,200o 1603 Grant – awards 30% of project cost

• Property Tax Exemption: 100% for first 5 years• Accelerated depreciation on the facility• Purchased by City at Fair Market Value following 5th year of operation

5 kW Wind Turbine• leveraged private sector investment with turbine donated to City

“It all adds up” [results] Wind Turbines: 155,000 kWh generated / year

Photovoltaic Solar: 9,600 kWh generated / year McCreary Comm. Center Lighting + HVAC: 70,000 kWh saved / year LED Public Buildings + Streets Lighting: 210,000 kWh saved / per year

LED City Hall Lighting: 195,000 kWh saved / per year Renewable Energy + Electricity Reductions: 639,600 kWh TOTAL

Annual $ Value of Renewable Energy Efficiency Measures using Alliant Energy standard rate schedule average rate: $0.13/kWh = $83,148

Annual $ Value of Renewable Energy Efficiency Measures using MidAmerican Energy standard rate schedule average rate: $0.09/kWh = $57,564

“It all adds up” [results]$ Value of Energy + Efficiency Measures over 25 years with 2.5% [Federal Energy Cost Escalation Factor] =

[Alliant Energy Territory]639,600 kWh 25 years$0.1776 [$0.13 compounded at 2.5%/year over 25 years]

= $2,839,824

[MidAmerican Energy Territory]639,600 kWh 25 years$0.1297 [$0.09 compounded at 2.5%/year over 25 years]

= $2,073,903
