Last Year’s CCC Results


Total Demonstration Houses Organized: 108

(76 returning and 32 new)

Combined curb footage cleaned of leaves each week: 9050 feet*

*At the end of November we ask each DH in our network to report to us via an online survey how many feet of curb they took responsibility for. We then sum the total from each DH to get our aggregated total.

OTHER CURB CLEANING NEIGHBORS (observed and reported to CACN)

Total other: 193 households (cleaned curbs at least once – observed by a DH or self‐reported to CACN via online Como forums)

Total curb area cleaned by others: 1930 feet*

* We estimate “other”curb cleaners do 1/4th as much as a DH. Our default for a DH is 40 feet of curb, so our default for an “other” is 10 ft. of curb.

9050 + 1930 = 10,980 feet of curb area cleaned

PLUG INTO OUR FORMULA provided by University of MN scientist, Dr. Sarah Hobbie: 10,980 feet of curb cleaned x .00125 pounds of P prevented per foot cleaned = 13.73 pounds of phosphorus prevented


CCC project grant: $5K

Pounds of P prevented: 13.73

Cost per pound of P prevented = $364

Compare to Arlington/Pascal underground stormwater facility

APF project cost: $799K

pounds of P prevented annually: 12

Cost per pound of P prevented = $66,583

We make this comparison because it is motivating to citizens to see we can prevent as much (and sometimes more) phosphorus than an existing treatment strategy for a fraction of the cost.

We also make this comparison to make the case that investing in citizen‐led prevention strategies like the Como Curb Cleanup has great ROI.

Other results:

We provided a Survey Monkey Questionnaire to DHs to collect information on the work they did, but also to learn if the CCC project has influenced them in other ways. For one question in particular, we found the results interesting, and gratifying. 43 DHs completed our survey – below is question 8 and in parentheses the number of these DHs who selected each option.

How has this project influenced or changed your curb cleaning practice, if any? Please select all that apply:

  • I have always cleaned my curb, so no difference. (7)
  • I clean my curb more than I used to because of this project. (25)
  • I never cleaned my curb before this project, but now I do. (6)
  • I pay more attention to organic material in the street gutter and try to keep it clean year round (seeds and flower parts in spring; grass clippings in summer; leaves in fall; sand and salt in winter). (22)
  • I am now exploring other strategies I can employ on my property and/or block to reduce sources of water pollution for our local lake and river. (5)

We were particularly pleased to see so many saying they clean their curb more than before and that they now pay attention to organics in gutters year round. Given this, we feel this project has a positive impact on citizen practices to reduce phosphorus sources beyond the Como Curb Cleanup project itself.
