- A cost assumption was made that any land acquired before 1991 was worth 25000 dollars per acre, and any land acquired in 1992 and after was worth 75000 dollars per acre.  This assumption was based on the Village’s Land/Cash Ordinance.  

- The following list of plots used actual prices:   

02-20-305-019  

02-29-124-001  

- The width of right of way for every street was rounded to either 66 feet or 80 feet.  

- The measurements for the right of ways widths and lengths were found in engineering’s Pavement Management System.  

Land plots were assigned to a year of acquisition by the dates on the acquisition deeds found at the county, or by information from the plot maps in the engineering department.

STORM DRAINS 

- The calculations for stormsewer were done using the cost and length of the entire stormsewer system (Even includes manholes).    

- Construction costs for the stormsewer were adapted and carried back to 1970, 1980, and 1990 from actual 2000 reconstruction costs of stormsewer, using price trends for the federal-aid highway construction composite index.    

- The total length of sewer built in each year (1970, 1980, 1990, and 2000) was computed by breaking up the total stormsewer system length using increments of population growth between the years.  The percentage of growth in each decade was set equal to the percentage of piping laid in that decade.  

The total length of the sewer system was provided by engineering’s GIS.  The cost of the stormsewer system was found in engineering’s records.  

Estimated useful life:

STREET/CURB/GUTTER  

- The engineering Pavement Management System (PMS) was used to find the lengths and widths of all roads.  

- The streets listed in the PMS were matched up to the latest village street map.  

- There are three categories for type of street: Residential, Residential Collector, and Industrial)  

- The Residential construction costs (measured in cost per foot) were adapted and carried back from actual 2000 reconstruction costs for residential streets using the price trends for federal-aid highway construction composite index.  

- The Residential Collector construction costs (measured in cost per foot) were adapted and carried back from actual 1997 reconstruction costs on Thunderbird Trail using the price trends for federal-aid highway construction composite index.  

- The Industrial construction costs (measured in cost per foot) were adapted and carried back from actual 1996 reconstruction costs on Kehoe Drive using the price trends for federal-aid highway construction composite index.  

All actual reconstruction costs for Kehoe Drive, Thunderbird Trail, and roads reconstructed in the year 2000 were collected from engineering records.

LIFE EXPECTANCY OF HOME COMPONENTS 

The life expectancies of the components of a home depend on the quality of installation, the level of maintenance, weather and climate conditions, and the intensity of use. Some components may remain functional but become obsolete due to changing styles and preferences or improvements in newer products while others may have a short life expectancy due to intensive use.  

The average life expectancy for some components has increased during the past 35 years because of new products and the introduction of new technologies, while the average life of others has declined. NAHB’s last such study on the life expectancy of housing components was published in Housing Economics in August 1993.  

APPLIANCES  

The life expectancy of a typical appliance depends to a great extent on the use it receives. Moreover, appliances are often replaced long before they are worn out because changes in styling, technology and consumer preferences make newer products more desirable. Of the major appliances in a home, gas ranges have the longest life expectancy: 15 years. Dryers and refrigerators last about 13 years. Some of the appliances with the shortest lifespan are: compactors (6 years), dishwashers (9 years) and microwave ovens (9 years).   

CABINETRY AND STORAGE

Kitchens are becoming larger and more elaborate, and together with the family room,  modern kitchens now form the “great room.”  Great rooms are not only a place to cook, but also a space where people gather to read, eat, do homework, surf the Internet and pay bills. Kitchen cabinets are expected to last up to 50 years, medicine cabinets for 20+ years, and garage/laundry cabinets for 100+ years. Closet shelves are expected to last for a lifetime.   

CONCRETE AND MASONRY  

Masonry is one of the most durable components of a home. Chimneys, fireplaces, and brick veneers can last a lifetime, and brick walls have an average life expectancy of more than 100 years.  

COUNTERTOPS  

Natural stone countertops, which are less expensive than a few years ago, are gaining in popularity and are expected to last a lifetime. Cultured marble countertops have a life expectancy of about 20 years.  

DECKS  

Because they are subject to a wide range of conditions in different climates, the life expectancy of wooden decks can vary significantly. Under ideal conditions, they have a life expectancy of about 20 years.  

DOORS  

Exterior fiberglass, steel and wood doors will last as long as the house exists, while vinyl and screen doors have a life expectancy of 20 and 40 years, respectively. Closet doors are expected to last a lifetime, and French doors have an average life of 30 to 50 years.   

ELECTRICAL AND LIGHTING  

Copper plated wiring, copper clad aluminum, and bare copper wiring are expected to last a lifetime, whereas electrical accessories and lighting controls are expected to last 10+ years.   

ENGINEERED LUMBER  

Floor and roof trusses and laminated strand lumber are expected to last a lifetime, and engineered trim is expected to last 30 years.   

FAUCETS AND FIXTURES  

Kitchen sinks made of modified acrylic will last 50 years, while kitchen faucets will work properly for about 15 years. The average life of bathroom shower enclosures is 50 years. Showerheads last a lifetime, while shower doors will last about 20 years. Bath cabinets and toilets have an unlimited lifespan, but the components inside the toilet tank do require some maintenance. Whirlpool tubs will function properly for 20 to 50 years, depending on use.   

FLOORING  

All natural wood floorings have a life expectancy of 100 years or more. Marble, slate, and granite are also expected to last for about 100 years, but can last less due to a lack of maintenance. Vinyl floors last up to 50 years, linoleum about 25 years, and carpet between 8 and 10 years (with appropriate maintenance and normal traffic).   

FOOTINGS AND FOUNDATIONS  

Poured as well as concrete block footings and foundations last a lifetime, assuming they were properly built. Termite proofing of foundations will last about 12 years if the chemical barriers put in place during construction are left intact. Waterproofing with bituminous coating lasts 10 years, but if it cracks it is immediately damaged. Concrete or cast iron waste pipes are expected to last 100 years or more.    

FRAMING AND OTHER STRUCTURAL SYSTEMS  

Framing and structural systems have extended longevities: poured-concrete systems, timber frame houses and structural insulated panels will all last a lifetime. Wall panels and roof and floor trusses will similarly last a lifetime. Softwood, hardboard, and plywood last an average of 30 years, while OSB and particleboard are expected to function properly for 60 years.    

GARAGES  

Garage door openers are expected to last 10 to 15 years, and light inserts for 20 years.   

HOME TECHNOLOGY  

Home technology systems have various life expectancies. While a built-in audio system will last 20 years, security systems and heat/smoke detectors have life expectancies of 5 to 10 years. Wireless home networks and home automation systems are expected to work properly for more than 50 years.  

HEATING, VENTILATION, AND AIR CONDITIONING (HVAC)  

Heating, ventilation, and air conditioning systems require proper and regular maintenance in order to work efficiently, but even in the best case scenarios most components of such systems only last 15 to 25 years. Furnaces on average last 15-20 years, heat pumps 16 years, and air conditioning units 10-15 years. Tankless water heaters last more than 20 years, while an electric or gas water heater has a life expectancy of about 10 years. Thermostats usually are replaced before the end of their 35-year lifespan due to technological improvements.   

INSULATION AND INFILTRATION BARRIERS  

As long as they are not punctured, cut, or burned and are kept dry and away from UV rays, the cellulose, fiberglass, and foam used in insulation materials will last a lifetime. This is true whether the insulation was applied as loose fill, house wrap, or batts/rolls.   

JOBSITE EQUIPMENT  

Ladders are expected to last a lifetime, and life expectancy of lifts is about 8 to 10 years.   

MOLDING AND MILLWORK  

Custom millwork will last a lifetime, and all stairs – circular and spiral stairs, prebuilt stairs and attic stairs – are expected to last a lifetime.    

PAINT, CAULKS AND ADHESIVES  

Both interior and exterior points can last for 15 years or longer, however home owners often paint more frequently.   

PANELS  

Hardboard panels and softwood panels are expected to last 30 years, while oriented strand board and particleboard have a life expectancy of 25-30 years. Wall panels are expected to last a lifetime.    

ROOFING  

The life of a roof depends on local weather conditions, proper building and design, material quality, and adequate maintenance. Slate, copper, and clay/concrete roofs have the longest life expectancy – over 50 years. Roofs made of asphalt shingles last for about 20 years while roofs made of fiber cement shingles have a life expectancy of about 25 years, and roofs made of wood shakes can be expected to last for about 30 years.   

SIDING AND ACCESSORIES  

Outside materials typically last a lifetime. Brick, vinyl, engineered wood, stone (both natural and manufactured), and fiber cement will last as long the house exists. Exterior wood shutters are expected to last 20 years, depending on weather conditions. Gutters have a life expectancy of more than 50 years if made of copper and for 20 years if made of aluminum. Copper downspouts last 100 years or more, while aluminum ones will last 30 years.   

SITE AND LANDSCAPING  

Most landscaping elements have a life expectancy of 15 to 25 years. Sprinklers and valves last about 20 years, while underground PVC piping has a lifespan of 25 years. Polyvinyl fences are designed to last a lifetime, and asphalt driveways should last between 15 and 20 years.  

Tennis courts can last a lifetime if recoated; most coatings last 12 to 15 years. The concrete shell of a swimming pool is expected to last over 25 years, but the interior plaster and tile have life expectancies of about 10 to 25 years.
