Public Works Open House

September 21, 2017 ~ 3-7pm ~ Public Works Department ~ 8635 W. Pt. Douglas Rd  

Cottage Grove residents of all ages are invited to enjoy displays and demonstrations of Public Works big rigs, snow plows, dump trucks, tractors and mowers.  Also enjoy a hayride, inflatable bouncers, balloon animals, face painting and food.  There will be several area vendors on location with plenty of freebies!

Boulevard Tree Trimming

Each year a portion of Cottage Grove is chosen to have the Boulevard trees trimmed.  Boulevard trees on the list and located in the City’s right-of-way will be trimmed beginning in December (weather permitting).  The boulevard, typically 10 to 15 feet from the curb to the property line, is part of the street right-of-way. Residents are asked to remove holiday lights on boulevard trees to eliminate safety hazards or damage to the lights.

Only trees in the city’s right-of-way will be trimmed. Dead, broken and crossing branches, as well as branches growing into other trees or down towards the ground or street will be trimmed. Removing sightline obstructions helps to prevent vehicle accidents and damage to larger vehicles such as fire, trash, delivery or snow plows.

Trimming will be done by both an independent contractor and City staff. The City Forester will be monitoring the process to ensure proper techniques and procedures are followed to benefit the tree. No more than one-third of the overall tree canopy will be removed, minimizing the amount of stress placed on each tree.

Tree trimming is necessary to improve shape, form, and vigor of the tree. Without trimming the life span of a tree is shortened by making it more susceptible to disease, damage and pest infestation.  Boulevard trees are on a five to six year rotational trimming schedule. 

Hydrant Flushing

To protect the City's water supply, all Cottage Grove water mains are flushed in the spring and fall. Public Works Department employees flush the water mains by opening each of the 1300 plus fire hydrants in Cottage Grove. The sudden rush of water loosens and removes accumulated mineral deposits from the lines. This process often causes discoloration of your water in the home.

The water is safe to drink, but it may stain fabrics if you are washing clothes at the time the water main is being flushed. Check for signs of discoloration before using the water to wash clothes. The Public Works Department suggests that each homeowner flush out the taps in their home at the same time water main flushing is done, since iron deposits tend to also build up in residential lines.


Nov. 1 through March 31, the Cottage Grove Winter Parking Ban is in effect. 

To facilitate plowing, parking on city streets is banned between 2 a.m. and 6 a.m. from Nov. 1 through March 31.

City ordinance No. 6-2-1 also prohibits on-street parking anytime there is a snowfall event, until after the street has been completely plowed. This applies to any hour of the day, any time of the year.  This allows the snowplow drivers to work safely and efficiently during the storm. 

Vehicles must be removed from Cottage Grove streets between 2 a.m. and 6 a.m. daily.  During a snow event vehicles will not be permitted to park on the streets at any time of the day to allow plows to clear the streets.  Vehicles parked on the street during this time will be towed at the owners expense (see ordinance 6-2-1). 

Residents and businesses are not permitted to plow and/or blow snow into/or across City streets  (      Sdsds    ... .   (see ordinance 7-1-3). 

The Public Works Streets division will begin snow removal when there is two inches or more of accumulated snow in the City. The process of snow removal from City streets, walking trails and sidewalks takes anywhere from six to eight hours to complete to ensure city residents safe traveling conditions.

All of the Public Works divisions including Utilities, Parks Maintenance and Fleet Maintenance assist the Streets division in snow removal to ensure the quickest and safest snow removal for the City’s residents.    

Spring Cleanup Day

The annual spring cleanup day is held on the first Saturday in May.

It's a day to drop off your unwanted items from 7 a.m. until 3 p.m. at the Public Works garage, 8635 W. Point Douglas Road.

Washington County residents may drop off hazardous materials, electronics, or recyclables year-round at the Washington County's Environmental Center, 4039 Cottage Grove Drive, Woodbury.

Street Sweeping

City crews will sweep streets in the spring, usually the first week of April - weather permitting. Residents should sweep sand from their boulevards onto the street before crews clean the streets and have vehicles parked in driveways so sweeping can be completed curb to curb.

Please remember that residents may NOT blow or rake leaves from your yard into the street.  Please see Ordinance 8-4-5 for more information.  

Cottage Grove conducts street sweeping for removal of the residual sand resulting from snow and ice control maintenance. All curbed streets are swept full width, typically in April. Fall street sweeping is used to help keep storm sewers clean and improve storm water quality and usually occurs in September weather permitting.

The City encourages residents to deposit any sand that has accumulated on the boulevard into the street near the curb prior to spring sweeping. This allows the street sweeper to remove the material and make spring cleanup easier for the residents. Residents are not allowed to place leaves or debris in the street for removal. 


Spring Road Weight Restrictions

MnDOT limits truck weights to prevent damage to roads weakened during the spring thaw. Beginning and ending dates for spring load restrictions will be established by monitoring roadway strength as weather conditions change.  Actual dates will be posted here when they are determined by the State.
