VILLAGE OF NORTHBROOK COOK COUNTY, ILLINOIS Tuesday, December 8, 2020
DATE: December 8, 2020
SUBJECT: COMMUNITY ACTION TOGETHER FOR CHILDREN'S HEALTH (CATCH)
Email Sent to Board of Trustees:
The importance of connectedness for our collective mental health during this time of isolation and social distancing cannot be underestimated.
CATCH knows that emotional well being is, in large part, dependent on feeling connected to one's community,
one's family and one's friends. Our slogan proposals reflect that and we are hopeful that the board will like one, or more, of these.
CATCH has come up with the following slogans for the Board to review. "Stay Connected One Northbrook" "Northbrook United Stay Connected" "Northbrook Cares Stay Connected" "Northbrook Cares Community Together"

1. Mission Brook Sanitary District’s Wholesale Water Agreement has a most favored nations clause in the agreement with the Village. This
sets their rate equal to the lowest wholesale customer’s rate.
2. The Village began supplying water to the Village of Riverwoods in FY 2007/08. The Wholesale Water Agreement limits their rate to
90% of the Village’s rate to its residents and businesses. Additionally, the Village of Riverwoods’ rate was locked until FY 2017/2018.
3. Village Board Approved $2.4 million Equity Fund Transfer from General Fund to the Water Fund to delay planned rate increase.
4. In FY 2020/21 the Village Board deferred the planned 10% water rate increase for Northbrook customers due to COVID-19.
