During September and October, construction will take place at the intersection of 70th Street and Meadow Grass Avenue. This is a cooperative project between the City and Washington County.
The project will involve the installation of a traffic signal and turn lanes at the intersection with anticipated completion by mid-October. The project will consist of the following elements:
Meadow Grass Avenue will be closed to both vehicle and pedestrian traffic during the turn lane construction phase of the project. The closure will take effect at 7 a.m. on Sept. 5 and is anticipated to continue through Sept. 30, weather dependent.
70th Street will remain open through the intersection, along with the paved trail along the north side of 70th Street.
The traffic signal is expected to be operational on Oct. 17, with final completion of the project by the end of October.
The general contractor for the 2014 Pavement Management Project is Valley Paving, Inc.
Construction began May 27, 2014. The estimated completion date is Sept. 5, 2014. Street construction is weather dependent, so the schedule is subject to change.
There are approximately five miles of streets within this project.
Since 1994 the City has been conducting a program to reconstruct streets throughout the community. This is referred to as the Pavement Management Program, which will eventually reconstruct or rehabilitate every City street on a given schedule. The 2014 scheduled Pavement Management area is in Districts F1 and F4 (see map).
The rehabilitation method proposed for the streets in District F1 and District F4 is to remove the existing asphalt surface and replace it with a new surface that will consist of two lifts of bituminous. Only spot curb replacement will be completed as needed. Also proposed are some minor utility improvements for sanitary sewer, water, and storm sewer.

The 2014 seal coat area includes Hillside Trail between Jamaica Avenue and East Point Douglas Road, the 2010 Pavement Management Project, the 2011 Pavement Management Project, East Point Douglas Road from Hardwood Avenue down to the Cul-de-sac, and the 2013 Pavement Management mill and overlay area. This project is scheduled to start on July 14, with completion by August 15.
Cars should not be parked on streets being seal coated. "No Parking" signs will be posted 24-hours in advance of seal coating.
Please refer to map or call Public Works at 651-458-2808 with questions.
Seal coating is a standard road maintenance procedure which involves placing a layer of rock and oil on the street to help project and prolong the life of the pavement.
The primary reason to seal coat a bituminous pavement is to protect the pavement from the deteriorating affects of sun and water. When the pavement is exposed to sun, wind and water, the bituminous hardens, causing the pavement to become more brittle. As a result, the pavement will crack because it is unable to bend and flex when exposed to traffic and temperature changes. A seal coat combats this situation by providing a waterproof membrane, which not only slows down the hardening process, but also helps the pavement to shed water, preventing it from entering the gravel sub-base material.
This work is completed each year in the seal coating project area to seal cracks and prevent water from permeating into the road surface. The 2014 project is scheduled to begin the end of May. It will be completed by Northwest Asphalt Maintenance.
As part of the City’s stormwater permit with the MPCA, the City is required to routinely maintain the storm sewer system, to ensure it is functioning properly and removing pollutants from the City’s stormwater before it is discharged into the Mississippi River. As part of this maintenance, annually the City selects a handful of stormwater ponds to maintain. This includes removing built-up sediment from the ponds, replacing rip rap around discharge pipes, replacing damaged structures, and removing vegetation that has grown in around the pond.
In 2014 the City plans to complete maintenance on three ponds. The first two are located in the Highland Hills development, directly east of Peter Thompson Park. The third pond is a dry pond, which is located in Hemingway Park
Annually, the City resurfaces a section of trails in Cottage Grove. This project is similar to the seal coating project, where a mixture of oil and rock is placed on the trails. This resurfacing is very cost effective, and protects the pavement and extends the life of the trail. Approximately eight miles of trail are scheduled for resurfacing in 2014.
Camel’s Hump Park will be constructed simultaneously with the Oak Cove Development. This new park is located directly south Oak Cove, on the bluff above US Highway 61. This park will include new paved and wood chip trails that will connect several scenic overlooks over the Mississippi River Valley. These trails will also connect to existing unsurfaced trails in the Minnesota Land Trust area to the east. Future plans include the construction of a park shelter, and extension of the paved and wood chip trails into the Minnesota Land Trust.
The Cayden Glen development, by Newland Communities, will include 92 single family lots. This development is located on the north side of 70th Street, directly west of the Eastridge Woods Development. Grading of the site began March 2014 and is scheduled to be completed the week of May 19, 2014. Street and utility construction began April 2014, and will last for approximately four months. Currently sanitary sewer is being installed throughout the site. Once street and utility construction is completed, construction of new single family homes will begin.
Grading of the new Cedarhurst Meadows Park in the Eastridge Woods development began during the summer of 2013. Last fall the grading was completed, along with the construction of some of the playground equipment. This spring and summer will see the construction of the rest of the park amenities, including a play mineshaft, a limestone climbing wall, edible and sensory gardens, and a sand play area. The park will also have a trail system that will connect with the larger trail system around the Watershed District’s drainage area and open space. These trails will provide connectivity between new developments and another great recreation experience in the Upper Ravine District.
The Clear Channel Ravine Stabilization Project is funded by the South Washington Watershed District to address major erosion issues in a ravine north of 70th Street, near Highway 61 and the western border of Cottage Grove. This has been an ongoing maintenance issue, with large amounts of soil being deposited at the bottom of the ravine near 70th Street.
During the fall of 2013, two stormwater basins were constructed on the south side of 70th Street, to control the amount of water that is discharged from the ravine. Stabilization of the ravine is scheduled for 2014. This will include addressing erosion that has occurred, installation of storm sewer pipe, and the construction of rip rap pools to control the rate of water flow. Finally, two stormwater ponds will be constructed to control the amount of water that can enter the ravine.
Eastridge Woods development by D.R. Horton is located on the northeast side of Cottage Grove, between Military Road and 70th Street. The first addition of this project got under way in 2013, with the development of 37 single family lots, Cedarhurst Meadows Park, and all of the corresponding utility and street infrastructure.
The new home construction began late summer 2013, and to date 19 building permits have been issued. Winter 2013 saw the construction approval for the second addition of Eastridge Woods which will include another 37 single family lots. Grading activities for the second phase began May 2014 and will last four to five months, with street and utility construction to follow.
Once completed, this development will include 134 new single family homes
The Everwood 3rd Subdivision, by MJR Developers, saw its final home constructed winter 2013. This development included nine single family lots along Aspen Cove, south of the Timber Ridge Addition.
MJR Developers is currently finishing the design phase of the Everwood 4th subdivision, which will include the final 10 single family lots in the Everwood development. Grading of this new development will begin early this summer, with street and utility construction to follow. This project will also require the construction of stormwater ponds along the west side of Hardwood Avenue, to treat stormwater from the development.
There will be several other public improvements constructed in conjunction with the Everwood 4th subdivision:
Meridian Land Company developed 29 single family lots in the Mississippi Dunes Estates 4th addition. The street and utility improvements were competed in 2013, and home construction began summer of 2013. New paved trails and a stormwater pond were also included as part of this project.
Home construction for 2014 is under way, with 17 building permits issued for new single family homes.
The Oak Cove development includes 12 single family lots by Meridian Land Company. It is located north of US Highway 61, directly west of the Everwood development. Grading and street/utility construction is scheduled to be completed by the fall of 2014. Construction of single family homes would begin shortly thereafter.
The Pinecliff 5th Subdivision by Lennar Homes, which included 27 single family lots located north of 65th Street and east of Hinton Avenue, had its final home built during the fall of 2013.
The City is currently working with the developer to have the construction of the final streets be completed during the summer of 2014. During this process the temporary pavement wedge will be removed, and the final lift of bituminous placed. Any damaged sidewalk or curb will be replaced at this time as well. This pavement wedge is put in place to help protect the concrete curb from being damaged by construction equipment and plows during the development phase.
This is a Washington County project. Construction is expected to begin mid- to late-July. The project will take about three months to complete.
The west leg of the intersection will be closed for a majority of the project. A bypass on the east side of the intersection is being built, similar to the roundabout construction at CSAH 19 and 22. The north, south, and east legs will be open for a majority of the project.

Sunnyhill Park, located in the Pinecliff development, is scheduled to be completed in 2014. Construction of this park began in 2012 with the installation of the playground equipment, picnic shelter, and some of the paved trails. During 2013 the finish grading of the park was completed. 2014 will see the installation of a sport court, completion of the trails, and final restoration. Expansion of this park is planned for the future, as development continues to the east of the Pinecliff subdivision.
The water tank (tower) located at 6950 Meadow Grass Avenue S. will be reconditioned beginning in April.
This work is expected to be completed by June 21, 2014. The City has contracted the work which will be done weekdays from 7 a.m. to 7 p.m.. There is a possibility of weekend work from 9 a.m. to 7 p.m.
This project includes the removal of portions of the existing coatings (paint) and application of new coatings (paint). During this process, there will be temporary installations of telecommunications equipment adjacent to the water tower. There may be some contractor vehicles parking along the driveway of the water tower site.
Because the contractor will be using abrasive blasting methods for spot exterior coating removal, a Containment System will be utilized to control the release of blasting emissions. Therefore, no dust emissions should be produced by the blast operations. During transfer of clean blast abrasive from the bulk storage tank to the blast pots, some dust may be visible.
Residents near the water tower may wish to take the following additional precautions during the project to minimize the potential inconvenience of this work:
The Meadow Grass Park playground adjacent to the water tank will be closed for safety reasons while the tank is reconditioned.
The 2013 Pavement Management Project was located in the neighborhood bound by 80th Street, Jamaica Avenue, 70th Street, and County Road 19. Along with the reconstruction of the streets in this neighborhood, several improvements to were made at Kingston Park.
Substantial completion of this project was reached in the fall of 2013. The contractor, Hardrives Inc., is currently working on completing a punch list of items. This punch list is made up of issues and repairs that need to be addressed before the project is fully completed. A major component of this punch list is to address areas where seeding has failed and restoration still needs to be completed.
The contractor was given the month of May 2014 to complete these restoration activities.
