The 50 percent rule in the flood hazard area
This is the single most important rule for anyone selling an older house near the river. In Garden City's Special Flood Hazard Area, any reconstruction, rehabilitation, addition or other improvement to a building that equals or exceeds 50 percent of the building's value must meet the same standards as new development.
So a buyer planning a major renovation is not just buying a renovation. Past that threshold the whole building has to be brought up to new-construction flood standards, which changes what the project costs and therefore what that buyer can pay. How the city calculates the building's value is a question for the city, and we do not estimate it for anyone.
Smaller work can still need the city. A floodplain application is required before working in the floodplain or floodway, before removing or damaging vegetation within 25 feet of the river or on the riverside of the greenbelt or nature path, and to request a Letter of Map Change to a flood map.
Water and sewer are a city system
Garden City's public water system is the Garden City Water and Sewer System. Federal records list it as owned by local government and supplied by groundwater, serving 12,500 people through 4,595 connections.
That is a different arrangement from Boise next door, where drinking water comes from private utilities regulated by the state. Federal records also list a few small private systems with Garden City addresses, so a particular property's water service is worth confirming rather than assuming.
Zoning, and an overlay worth checking
Garden City runs its own planning. Its Planning Division handles annexation, zoning, conditional use permits, design review, signage and subdivisions, and like every city in Ada County it administers land use inside its own limits under its own code.
The uses allowed in each zoning district are set out in Garden City Code Table 8-2B-1, with further conditions on some uses under Code 8-2C. A property can also sit in the Neighborhood Commercial Node overlay district, whose allowed uses are in Table 8-3A-1. District letters here mean what Garden City's code says they mean, and they do not carry over from neighbouring cities.
Roads belong to the highway district
Garden City sits inside a countywide highway district, and Idaho law bars a city in that position from maintaining or supervising city highways or taxing for them. A question about a curb, a driveway approach or the frontage of a Garden City property is a highway district matter.
Projected growth, from a small base
COMPASS, the regional planning association, projects Ada County will reach 715,820 people by 2050, with the growth very unevenly distributed. Garden City is projected to grow 42.0 percent, against 25.8 percent for Boise and 128.7 percent for Kuna, while unincorporated Ada County is projected to lose 36.0 percent of its population.
Garden City starts from the smallest base of the county's cities, so a large percentage is still a modest number of people. A projection is not a forecast of prices and we do not treat it as one — but it does show where the region's own planning expects people to go, and a riverside city with little open land is not a place that absorbs that growth by spreading outward.
What that means for an offer
A Garden City property in the flood hazard area, or one that needs more work than the 50 percent line comfortably allows, is not one we decline. It is one where the rules shape the number, and we would rather show you how they do.
When we make an offer we show the value we used, the work we think the property needs, our holding costs and the margin we run on. You can check every line.
