Let me not mince words….slip lanes are the bane of a pedestrian friendly downtown business district, but they may have a larger impact than that on your cities finances.
From a planning perspective, they facilitate fast travel and are suitable for highway on-ramps, rural highways, and places where there isn’t a chance in hell someone is walking or downtown businesses are trying to thrive. I also like to think of things in terms of value and how things build a cities tax base and that is where I intend to head with this post, not the traffic calming rant I seem to have started on.
To illustrate the point I will be making, I am picking on a particular intersection that has four right turn slip lanes, going in each direction and facilitating an effortless cornering maneuver for motorists. As I implied earlier, these are great for places where no one in their right mind would walk, but what are the costs when it is located in what should be a thriving downtown business district?
The marked areas in the map below represents almost 3/4 of an acre of land consumed by the transportation “investment”, and is at the south end of a somewhat thriving downtown (getting better by the day I might add). The block south of downtown sits a old mill that is witnessing a resurgence and has been the recipient of significant private investment dollars, yet when navigating this intersection, it may as well be a mile away. Not only is the street network designed for Interstate traffic (5 lanes including turn lanes), but the slip lanes lead you right into the heart of downtown at breakneck speed.
Not that everyone drives this fast when approaching the downtown business district, but the transportation network certainly doesn’t prevent it. In other words, it happens frequent enough for me to notice.
In terms of our point about the lost value to the city, these slip lanes represent what could be development opportunities for ‘thee’ prime location in the City. Not only is it close to the neighboring town across the river, but given the right changes in zoning code, these properties could allow for significant investment, never mind the fact that developing these properties is probably illegal according to the towns (and every other towns) current zoning code.
If I were a good (even remotely decent) graphic designer, I would crank out a sketch-up of these properties as they would look if developed with downtown buildings, with no setback from the street’s ROW (right of way). Not only would this add tax paying properties to the City, but would serve as a continuation of the downtown corridor linking the investment in the mill just south of downtown. As one approaches the City coming in from across the river, one would know they were arriving somewhere worthy, a place to arrive to, instead of a place to drive through.
Some might argue that the properties are too small for significant investment, but if we look at the property just north of the 0.19 acre property, it is actually only .145 acres and on it sits a very nice building that sadly is suffering from lack of investment. By combining the property that is 0.33 acres with the property (large parking lot along the river with 1.165 acres) to the northeast, you end up with a property large enough to build a great building site and provide some adequate parking. The same is the case with the parcels on the south end of the intersection.
I began this post thinking about tax revenue for the city and how to increase value. So lets play with some numbers… Pretend each corner attracted an average investment of $1M. At our current tax rate, that would represent an additional $96,000/year in tax revenue if my calculations are remotely correct. Considering that the infrastructure (street, water, sewer) is already in place in this area of town, this investment would be gravy for the city. They could either make other strategic investments in attracting business, or over time, reduce the tax burden on each property owner after the changes in the transportation system that led to this are reimbursed.
I keep looking at the places I happen by and see opportunities from strengthening communities everywhere. I won’t talk about why there is a 5 lane bridge between the two towns at this time, or the one-way streets that also facilitate fast traffic, but that too should be considered in a holistic fashion along with this. Perhaps the towns comprehensive plan will address these issues or a more narrowly focused downtown master plan could offer some direction? At this point it isn’t my place to bring these up, but hope that someone with more clout than myself, might run with it? These are all complicated issues and can’t be looked at in isolation, but it is good to start somewhere.
