2008 Iowa Real Property Appraisal Manual, May 2008

********NOTE: There are nine sections to this manual, all in separate files.************* **********NOTE: Large files may take longer to open******** The basis of real property assessment in Iowa is market value as defined in Iowa Code §441.21. Iowa Code §§ 421.17(17) and 441.21(h) provide that assessment jurisdictions follow the guidelines and rules in this manual to help achieve uniformity in assessments. Assessors are encouraged to use the International Association of Assessing Officers’ Standard on Mass Appraisal of Real Property in their mass appraisal practices. Estimating market value in mass appraisal involves accurately listing properties, developing a sales file that includes the primary influences on market value, and developing models for subsets of properties that share common market influences using recognized mass appraisal techniques. The assessment of an individual property should not be based solely on the sale price. The Uniform Standards of Professional Appraisal Practice (USPAP) standard 6 says “In developing a mass appraisal, an appraiser must be aware of, understand, and correctly employ those recognized methods and techniques necessary to produce and communicate credible mass appraisals.” Accurate listing of property is the basis of a good mass appraisal program. On-site inspection and listing of property is essential in developing a good data base for revaluation. A physical review, including an on-site verification of property characteristics, should be conducted at least every four to six years. Land values should be reviewed every two years. Factors influencing the market of each property type should be identified and collected so that these factors can be considered in the mass appraisal model. It is equally important to maintain the data once it is collected. Accessing local government permit systems should be a part of a good data maintenance program along with an inspection program. Current cadastral maps and geographical information systems (GIS) are tools that are integral in checking accuracy of listings and maintaining a comprehensive data base.

RAGBRAI Learn about the Land; Day 1, July 2008

Want to know what conditions to expect over the next stage of RAGBRAI? How hilly will it be, what towns and parks are between here and there, or what services are coming up in the next town?

RAGBRAI Learn about the Land; Day 2, July 2008

On today’s ride we continue riding across the Southern Iowa Drift Plain. This landform region covers over 40% of the state and comprises most of southern Iowa. Over the last several million years Iowa was subjected to at least seven glacial advances. The last of these older advances occurred approximately 500,000 years ago. Since then the landscape has been subjected to stream erosion and from12,500-24,000 years ago was mantled with a thick blanket of loess before being further eroded.

RAGBRAI Learn about the Land; Day 3, July 2008

Although during much of its geologic history Iowa was part of an interior sea, today what we see on the land surface has been heavily influenced by recent glaciation. Everything from Iowa soils, rivers, lakes, and hills has been influenced by glaciation. Most of Iowa’s bedrock is hidden beneath a thick mantle of deposits from the Cenozoic (i.e., new life) Era, spanning the last 65 million years. Geologists have divided the Cenozoic Era into two periods. These are the Tertiary (1.8-65 million years ago) and Quaternary Periods (recent to 1.8 million years ago). Most geologic records in Iowa are from the Quaternary period, and include glacial till and loess.

Today’s ride departs Ames and heads towards Nevada. The Ames area is one of the classic areas to view elongated hummocks. These landforms are discontinous, lower relief curvilinear ridges which are east-west trending features. At one time geologists thought these hummocks formed at the base of the glacier due to glacial movement. It is now understood that these features may have developed within the glacier, in a large crevasse field that formed behind the ice (Bemis Moraine) margin as the ice stagnated and melted.

RAGBRAI Learn about the Land; Day 5, July 2008

Today, after you descend into the valley of the Iowa River north of Marengo, the route turns east on county road F15 and approaches the historic Amana Society. Settled in the late 1850s by German immigrants of the Community of True Inspiration, the new arrivals utilized the local timber and stone resources to construct their buildings. During these early years several stone quarries were opened in the hills along the north wall of the Iowa River valley near East, Middle, and West Amana. Riders will pass close to one of these old quarries 0.7 miles west of West Amana. The stone taken from these quarries is beautiful quartz-rich sandstone that is cemented by light brown to orange tinged iron oxide. This stone was used in the construction of many buildings in Amana.

Today you will be biking over the Iowa and Cedar rivers, two major rivers hit by the Iowa flood of 2008. Three miles northeast of North Liberty you’ll cross the Iowa River. The river crested on June 15, 2008 at a record 31.53 ft., three feet higher than the previous record during the flood of 1993. The flooding river caused extensive damage to the University of Iowa (see cover photo of Iowa Memorial Union taken by Univ. Relations, Univ. of Iowa), Coralville, and numerous smaller towns. The flooding of the Cedar River, which RAGBRAI will cross at Sutliff, caused even greater damage. At Cedar Rapids, the 2008 flood crest of 31.12 ft. was over 11 ft. higher than the previous record set in 1851! This massive amount of water inundated downtown Cedar Rapids, Palo, and Columbus Junction and caused massive damage to buildings and infrastructure. When crossing the Cedar River at Sutliff, be sure to look to your right to see the remains of the Historic Sutliff Bridge, one of the many casualties of the Iowa flood of 2008.

RAGBRAI Learn about the Land; Day 7, July 2008

Iowa’s land was mapped long before it was declared a state. Since Lewis and Clark published their journey across the North American west in 1814, many different uses for maps have been found. Today there are maps of Iowa’s roads, waterways, landscape features, geology, and land use. One of the more recent mapping efforts has involved using a technology called LiDAR. This technology creates a topographic map of Iowa’s elevation that is accurate to within eight inches, ten times higher resolution than in previous elevation maps.

Making land-use fit to planning goals. Weaknesses and opportunities within the Swiss land management regime

In Switzerland, the issue of land consumption has made it to the front of the political agenda in recent years. Studies conducted on a national level have concluded that there is an excess of land zoned for construction (ARE, 2008), which is seen as contributing to urban sprawl. This situation is looked upon as a failure of the Federal Law on Spatial Planning (LAT, 1979) and there is a political push to change it in order to reinforce zoning regulations. In this article, we look on the issue from a different angle. While there may be large quantities of land zoned for construction, in many urban areas land actually available for development is scarce. Building on the idea that planning's efficiency is linked to its capacity of influencing actual land-use, we focus on how this situation can be dealt with within the current Swiss institutional context.

The choice of titling system in land

This paper analyzes the choice of the socially optimal titling systemassuming rational individual choices about recording, assurance andregistration decisions. It focuses on the enforcement of propertyrights on land under private titling and the two existing publictitling systems, recording and registration. When the reduction in theexpected costs of eviction compensates the higher cost of initialregistration, it is more efficient to introduce a registration systemrather than a recording system. The development of private "titleassurance" improves the standing of recording as compared toregistration. This improvement depends, however, on the efficiency ofthe assurance technology and, also, on corrective taxation that isneeded to align individual optimization, which disregards the transferelement in eviction, with social objectives.
