Dear Mr. Howard, Mr. Peden, Mr. Meyers, and Mr. Rollo, We are the property-owners at 2017 E Marilyn Dr. abutting Mr. Howard’s residential construction project at 1110 S. Covenanter Dr (http://howardshomeimprovement.com). We're writing because we're concerned about the addition of gravel this past week to Mr. Howard’s lot, raising it several feet above our property, creating what looks sure to become a pond of run-off water along the eastern edge of our property and causing likely flooding at the southern edge. A marshy meadow that used to collect water on Mr. Howard’s property has been shifted onto our property. In order to get a sense of the impacts and the city’s review of them, we are hoping to talk with Mr. Howard and a city inspector before further work proceeds. We are also concerned that the property line has not been staked and our property is being used for construction staging, with considerable removal of vegetation and possible spreading of gravel across the property line. Here is a rough calculation of the drainage runoff from Mr. Howard’s property onto ours: The raised area is 30’+60’+10’=100' X 12’ = 1200 sq ft (at the side) and 22’ + 12’ = 34’ X 10’ = 340’ sq ft (at the back) = 1540 sq ft (total). At an average 5” rainfall in May, that would create 4,800 gallons or 640 cu ft of runoff. Annually, rainfall is about 50” so the runoff would be about 48,000 gallons or 6400 cu ft per year. But with climate change we suspect those amounts are going to increase (rainfall for every month this year has exceeded the norm). We arrived at this estimate using the USGS rainfall calculator: https://water.usgs.gov/edu/activity-howmuchrain.html And we used rainfall estimates from: https://www.weather.gov/ind/Precip_scorecard_IND For the raised area of Mr Howard’s property, we used the schematics attached below. We also have attached photographs showing the construction staging on our property, and the effect of the land build-ups on the east side of our property line. Thank you for your help, Ben and Jenny Robinson
