As a City Councilman in a Texas city years ago we shared many of the same dynamics being experienced here in Camas. Opposition to spending tax money on trail systems seemed to be an unnecessary expense to many people. Our data, though, showed that communities which invested in parks and trails saw property values rise and business revenue increase resulting in a net positive contribution to city revenue. We proceeded with an aggressive trail and park plan, and a decade later we were named 7th Best Places to Live in America by Money Magazine. The article raved about our town having "the best bang for the buck" and highlighted our "immaculate parks".
Home values increased at a greater rate than surrounding communities because of the parks which resulted in tax rates being adjusted LOWER than those in other communities. Our local businesses also saw increased sales from customers outside of our city which brought in additional tax revenue.
If you like the idea of trails in Camas, that's great. But even if you never use parks and trails and your only concern is your taxes, that's great too, because one of the best investments a city can make is in it's parks and trails. Simply Googling the topic will prove my point.
