Historic Air Quality Dashboard

The city operates a network of air quality sensors. The vendor, Clarity Movement, hosts a [real-time map showing live air quality](https://map.clarity.io/a2aq/) and offers the ability to sign up for alerts.

That map only shows thirty days of data and makes it hard to compare across stations. This historic dashboard shows *all* of the city's historic air quality data and offers a greater variety of visualizations.

Bike Lane Obstructions

The City of Ann Arbor's Police Department has developed a [comprehensive enforcement strategy plan](https://a2gov.legistar.com/View.ashx?M=F&ID=14048040&GUID=5134FC73-1E5D-4B93-81E9-4D3D3DB93298) to improve the safety and accessibility of bike lanes by addressing parking, driving, and object placement violations, with efforts spanning public outreach, enforcement, and education. This initiative includes a data visualization platform that displays time data on police dispatch calls, citations for bike lane obstructions, and A2 Fix It requests related to vehicles and curb carts in bike lanes, with an interactive heatmap available under the ‘spatial’ tab to identify hotspots.

The data is refreshed during the first week of the month, providing valuable insights to support ongoing efforts to foster a safer environment for cyclists, pedestrians, and drivers.

Floodway

 "Regulatory Floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. Communities must regulate development in these floodways to ensure that there are no increases in upstream flood elevations. For streams and other watercourses where FEMA has provided Base Flood Elevations (BFEs), but no floodway has been designated, the community must review floodplain development on a case-by-case basis to ensure that increases in water surface elevations do not occur, or identify the need to adopt a floodway if adequate information is available. Created by Systems Planning based off of FEMA floodplain info. In the process of being updated based on newest FEMA data.

Air Quality Sensor Data

Hourly air quality data collected by the city. The dataset begins in 2022 with data from a few stations that used AQMesh-brand sensors. Then it switches over to a few Clarity-brand sensors, and finally expands to ten Clarity stations. We have combined the two datasets into a single one here. You can use the "vendor" column to differentiate.

The city's Air Quality Dashboard visualizes this data; we are also making it available here for further exploration.

Rainfall at City-Operated Rain Gauges

The City of Ann Arbor operates and maintains five tipping​ bucket rain gauges​ (5-min resolution) which are located at Barton Dam, South Industrial Hwy, Jackson Ave​/Parklake Ave, University of Michigan North Campus Area and City Hall​​​. This file contains the data from those gauges in 15-minute increments. Rainfall is visualized on our public-facing dashboards; we also offer the raw data here.

The city populates a record of 0.00 inches for the interval 11:45pm-midnight every day for each gauge, unless rainfall occurred during that time in which case the value is preserved. We also temporarily populate a record of 0.00 for the latest timestamp that each gauge has reported data from, to make it clear when the gauge last called in. 

Since we began collecting this data in 2013, individual gauges have intermittently gone offline and/or reported invalid rain totals (either too high or too low). We have expunged some invalid rain total values for this .csv but these limitations of data incompleteness still affect this dataset.

Building Footprints

The building outline dataset for the City of Ann Arbor. Includes the average height of the structure.

Woolpert completed a semi-automated method for building generation utilizing new countywide 2009 LiDAR data and existing 2005-2008 orthoimagery. Buildings over 100 square feet were generated and run through a QC process. The final building polygons were developed for the entire ±709-square mile county area. The dataset has had all but those footprints near or within the City of Ann Arbor and contains an average building height. Updates are currently done with new construction plans and then verified using the newest aerial imagery.

A2 HERDMap

The Home Energy Rating Disclosure​ (HERD) Ordinance provides consumer protections by requiring that a Home Energy Score (HES) assessment be conducted before a home lists for sale. The HES Assessment produces a score and a report that will provide home buyers information on a home's potential energy use and costs. HERD makes a home's energy use easy to understand, like a miles-per-gallon/charge rating for a vehicle. Learn more on [the city's HERD webpage](https://www.a2gov.org/sustainability-innovations-home/sustainability-me/home-energy-rating-disclosure/).
