Brookline Reservoir Park
MWRA Water Line Break/Reservoir Park Damage/Walking Path Changes
The work related to the MWRA water main break is substantially complete. Much of the work to the armor stone around the reservoir was completed late January into February. Due to weather, the construction was shut down in February into early March. Final work renovating the walking path, the adjacent landscape and seeding was completed in late March.
January 2021 Update
Work has begun on repairs to the reservoir park. The work in being undertaken by David G. Roach & Sons, Inc. of Hardwick, MA. This is the site contractor who recently performed the work at the reservoir. The water level of the reservoir has been lowered by the town in order to accomplish this work. The contractor will be working on removal of sediment at the reservoir edge; re-setting the armor stone at the edge of the reservoir; replacement and renovation of the stone dust walking path; and general regrading of lawn areas and other work necessary to restore the park back to its original conditions prior to the water main break. The repairs are being paid for by the MWRA.
November 21, 2020 Update Temporary Pathway Now Open
MWRA completed the temporary pathway on Friday, November 20th and this was opened for the weekend. The temporary pathway, constructed of stone dust, similar to the main pathway, allows users to complete the full loop around the reservoir. There is temporary fencing to separate the work area along the reservoir. One lane of Lee Street was opened on Friday as repairs to the sidewalk and slope embankment continue. As soon as this work is completed and the guard rail repaired, the other lane of Lee Street will be re-opened. The Department of Public Works continues to work with MWRA and their staff on permanent repairs to the damage within the park. We expect to provide and update as to scheduling of this work in the coming weeks. Though we anticipate the work may occur over the winter (weather dependent), there will ultimately be some finish work that occurs in early spring. In the meantime, we are pleased to have the walking path opened for a full loop around the reservoir.
Temporary Pathway as of 11.21.20 now open to the public.
November 19, 2020 Update
The roadway was paved today. Only a binder course was placed for the winter. Final paving will be completed in the spring. Tomorrow one lane on the northbound side of Lee street will reopen and both lanes on the southbound side will be open. The one lane on the northbound side will remain closed until work is completed on the embankment. Work continues on the temporary pathway as well.
Temporary Pathway Progress
November 18, 2020 Update
Today, CDF was poured in the excavated area and the blow-off frame and covers set. Also, the existing pavement around the break area was cut back 10-feet to prepare for paving tomorrow afternoon.
November 16, 2020 Update
MWRA continues to work on the repair to the water main within Lee Street, with a top priority to fix the water line and also re-open the roadway. Parks and Open Space staff met on site today with the MWRA team to assess the park. MWRA is working on plans with their engineering staff for repair of the damage. They will create a work area at the edge of the reservoir, which will remain fenced off while the repairs occur. Outside of this fenced in area, there will be a temporary pathway created to complete the walking path around the reservoir. This will be located safely outside the work area and will allow residents to walk in a complete loop around the reservoir while the repairs are occurring. There may be times at which it is necessary to close this temporary pathway during repairs. MWRA has not yet provided a schedule for the Today, CDF was poured in the excavated area and the blow-off frame and covers set. Also, the existing pavement around the break area was cut back 10-feet to prepare for paving tomorrow afternoon. Full repair within the park, as they continue to assess the damage and develop the plans for the repairs. We will be working with the MWRA to get the temporary pathway in place as soon as the waterline and roadway repairs are completed.
November 12, 2020 Update
On November 12, 2020 at around 10:30 AM, there was a major water line break on Lee Street. This water line is part of the MWRA water distribution system and according to MWRA, this pipeline serves the Single Tree Storage Tank from the Newton Street Pump Station. The 48” diameter cast iron water line break caused a massive amount of water to flood into the Brookline Reservoir. There was no immediate impact to the reservoir itself, however it did raise turbidity levels in the western portion of the reservoir. We will continue to monitor impacts to the water within the reservoir in the coming days and weeks. As a result of this water line break, there was, however significant damage inside the park, including the riprap edge of the reservoir, stone dust pathway, swale, plantings and berm. As a result of this damage, this portion of the walking path will remain closed while repairs are undertaken. The Parks and Open Space Division will be working closely with the MWRA to get the area stabilized, safe and repaired as soon as possible. We thank you for your patience during this time.
June 2020 - Brookline Reservoir Park Opening
We are thrilled to announce that the Brookline Reservoir Park is officially open to the public! We are so excited to share this new & improved open space with our community. Please take note of all the signage at the park regarding Covid-19 precautions - there is a one-way traffic pattern and all park visitors should practice social distancing. If you visit the Reservoir, please take a picture and tag us @brooklineparks! #brooklineparks
Following the generally mild winter, the contractor was able to continue his work on the overall park project. However, the very wet spring that followed has slowed some of the finish work on site. The historic preservation work on the Gatehouse was completed, and new work began on constructing a unisex restroom within the Gatehouse.
We are in unprecedented times given Covid-19, but are considering opening the park back up in early June 2020, pending further local and state guidance. Opening the park will likely necessitate proper social distancing, and we will need to establish a temporary one-way traffic pattern.
The reservoir was re-pointed and has been re-filled to its full level. The stone dust pathway around the reservoir has been renovated and also expanded in front of the gatehouse, creating a vastly improved experience for walkers and runners. Along a large portion of the stone dust walkway along Route 9, a new ornamental iron fence was installed. The landscaping has been completed, with new plantings throughout, and many different areas newly seeded as well. New entry pathways were also brought into the park from the Dudley Street side, with an improved handicapped entrance at the Dudley and Lee Street entrance. The Parks and Open Space Division worked through the winter on a complete refurbishment of the 57 benches from the Reservoir Park, which have now been returned to their respective locations. The park contractor has some specific work left to be completed, including:
- Installation of chip seal surfacing on paths and maintenance driveway, recently paved (Dudley side)
- Installation of granite stairs and adjacent concrete walkway at Rt. 9/ Warren St intersection
- Installation of loam and seed adjacent to sidewalks and driveway at Rt. 9/ Warren St intersection
- Finalize electrical wiring at Gatehouse
- Installation of the new light pole and fixture at reservoir near the Gatehouse
- Completion of mortaring of the stone wall on Rt.9 Retaining wall (inside park)
- Compact stone dust path from main trail to stairs off Walnut Street
- Loam and seed various areas throughout the site where grass has not established
- Clean-up miscellaneous debris around site
- Install hand rails on driveway up to reservoir and granite stairs
- Installation of concrete trash pad off Dudley Street.
- Other miscellaneous site work including final site clean-up
In addition, the new restroom under construction within the Gatehouse will be completed.
The contractor has continued work through the early winter on both the park renovation contract as well as the gatehouse improvement contract. The improvements to the gatehouse are nearly complete, with only a few detailed finishing touches on the doors remaining. The exterior improvements to the gatehouse have restored it to the extraordinary architectural structure that it truly is.
For the overall park renovation, exterior work has been progressing through the fall and into winter, given the generally mild weather conditions we have experienced. The reservoir is almost completely re-filled with the great amount of rainfall we have experienced. With one foot remaining until it is back to its normal level, we expect the reservoir will be fully re-filed by spring. A significant amount of the exterior work is completed, which includes the new valve work within the gate house, slope stone repointing around the reservoir, path widening in front of the gatehouse and resetting capstones along Route 9. In addition, the pathway re-construction is mostly completed, new concrete bench pads, the new ornamental iron fence installed, as well as a new bus shelter, and various landscaping improvements. There is some work remaining within the gatehouse which will continue over the winter through completion. Various park work will continue to be completed as the weather allows, with all remaining work to complete in the spring. Some of these items include final stone dust pathway grading and compaction; pathway paving at the various entrance points; granite curbing at the Warren Street entrance; new sections of concrete sidewalks along Route 9, Warren Street, Dudley Street, and Dudley Way; loam and seed remaining disturbed areas; granite steps and handrails; drinking fountain and light pole installation. Finishing touches will include re-installing the 58 completely refurbished benches around the park. We are hopeful to re-open the park in the spring of 2020, weather dependent.
A separate contract to construct a new rest room within the gatehouse, will occur this late winter into spring. As of mid-January, this project is out for public bid. It is anticipated, this work will also be completed in the Spring of 2020.
There continue to be two construction contracts underway, one for the Brookline Reservoir Park renovation and one for the exterior improvements to the Brookline Reservoir Gatehouse. The park work is approximately 50% complete, and we just had a 50% review by the Massachusetts Department of Conservation and Recreation’s Office of Dam Safety with positive feedback. The exterior improvements to the gatehouse are 95% complete, with the only remaining work items being installation of the refinished windows and new doors. This exterior work was funded in part by the Massachusetts Preservation Projects Fund administered by the Massachusetts Historical Commission.
Progress on the park renovation is as follows:
- Donor Opportunities: The existing donor benches that have been removed for refurbishment and reinstallation with their donor plaques have been an integral part of the character of the park, and a number of people have expressed interest in additional donor opportunities to commemorate loved ones. Town staff is preparing a master plan for these opportunities, including different kinds of site furniture beyond the traditional benches and signature trees.
- Valve Work: Work on the valves inside the building is complete, with concrete infill in place for the chambers that were taken out of use and two new 16 inch gate valves installed. The coffer dam that was installed to accommodate this work has been removed, and the reservoir is no longer being dewatered.
- Utilities: New water and sewer lines have been installed at the gatehouse to serve the new restroom, construction of which will be the third and final construction project as part of the overall improvements. New electrical supply remains to be done.
- Slopes on Top of the Dam: Clearing and grubbing of the slopes on top of the dam structure is complete, and topsoil is being placed in preparation for seeding with ornamental grasses.
- Ornamental Metal Fencing: Submittals have been approved for the ornamental metal fencing, including a sample panel, and fabrication has begun. This fence will run along the dam to provide a sense of security and safety, especially where the stone dust path is elevated above the adjacent roadways and properties.
- Granite Masonry: Shop drawings for the new granite stairs with cheek walls and granite steps for the entrance off of Route 9 and Warren Street have been approved, along with a granite sample, and the stone is being cut. The general contractor, David G. Roach & Sons, has reset the granite cap stones for the stone retaining wall at the dam that had shifted. Town crews will be repointing the retaining wall.
- Stone Dust Path: Replacement of the existing stone dust walking path has just begun, with excavation of the top course and subbase drainage layer, and placement of new stone dust. The interior of the reservoir basin at the path’s pinch point in front of the gatehouse is being reworked and has had its stones numbered and recorded so they can be replaced as part of the effort to widen the path.
- Next Steps: Upcoming work will include reworking the electrical supply at Warren Street and Route 9 to eliminate the utility pole at the corner and provide new lighting at and near the gatehouse. We plan to tag the plant materials in the nursery relatively soon to ensure that we have a good selection. Final layout of the ornamental metal fence will be worked out in the field. We have provided comments on the review set for the bidding of the restroom in the gatehouse and will put that package out to bid as soon as the revisions are made.
- Budget and Funding: The project is valued at $3.1 million and is funded by $2.2 million in capital funding, $500,000 in stormwater/drain infrastructure funding and $400,000 from the Commonwealth of Massachusetts’ Executive Office of Energy & Environmental Affairs Dam and Seawall Repair or Removal Program in addition to the Massachusetts Preservation Project Fund mentioned above. There were deadlines associated with the two state grants, and the grant funds were expended before the due dates.
- Schedule: Work is expected to be complete and the park reopened in the spring of 2020.
At this point the Brookline Reservoir Park construction project is approaching one month of work on site, and work is progressing steadily on the park and gatehouse improvements as part of two separate construction contracts. David G. Roach & Sons is responsible for the park improvements, including utility improvements inside the gatehouse, and the status of their work is as follows:
- Site Preparation - As part of securing the site and preparing for the construction, temporary construction fencing was installed accompanied by job signs describing the project and notifying the public that the park is closed for safety reasons. Erosion controls, including a gravel construction entrance off of Dudley Way, and silt socks to catch sediments before they can travel into the basin or off-site are in place. In addition, corrugated plastic pipes have been placed to protect the trunks of trees that are vulnerable to construction damage.
- Tree Removals - The removal of trees on top of the dam structure, as worked out with the Commonwealth’s Office of Dam Safety (ODS), and elsewhere on site as determined by the Town’s Arborist who identified existing trees suffering significant decay, is almost complete. As described in last month’s Project Update and other communications, a multi-year process was undertaken with the ODS, initiated by a directive per the regulations to remove all trees and shrubs on top of the dam and plant the area with grasses that could be mowed periodically to allow for visual inspection. This is the standard treatment for dams across the state, the intent being to maximize structural stability that could be compromised by uprooted trees, penetrating roots, and burrowing animals. The relationship of the dam to the surrounding densely populated area and the topography mean that although the ODS considers the dam to be well maintained, the risk of loss of life and property should the dam fail could be very significant. The Parks and Open Space Division worked with the ODS to develop an alternative plan that ensured the integrity of the dam while maintaining some trees on the dam, particularly Cherry trees, located above the water elevation. This plan involved a survey of the existing vegetation, a series of meetings and site visits with Town staff including the Town Arborist, ODS staff, and engineering consultants retained by the Town who specialize in dam improvements, plus development of a Tree Management Plan and a commitment to regular inspections. The changes proposed, especially the tree removals on the dam which is located on either side of the gatehouse and occupies approximately 40% of the reservoir’s perimeter, while necessary, are a profound change to the visual character of the park. We will be replanting some of the Cherries that were removed on top of the dam that were in decline as well as planting a variety of shade trees elsewhere that will provide a greater variety of species and visual characteristics. In addition to the job signs posted on the construction fence, we have placed A-frame signs around the park’s perimeter describing the need for the tree removals.
- Removal of Invasive Plant Species - Invasive upland plant species such as Black Swallow-wort, Multiflora Rose, Garlic Mustard, and Tree of Heaven have been removed and disposed of appropriately, and the affected areas grubbed. These areas will be replanted with trees, shrubs, and a woodland seed mix.
- Selective Demolition and Removals - Demolition of items such as concrete bench pads that need to be replaced is complete. Trash receptacles have been removed and will be replaced by Big Belly trash and recycling units. Benches have been removed in order to be refurbished and reinstalled.
- Dewatering for Valve and Masonry Repair - Drawing down the water in the Reservoir basin is complete, leaving approximately half of the basin with water with depths ranging from a few inches to eight feet deep. (The original depth was a maximum of approximately twenty feet.) The dewatering was necessary in order to perform work on the underwater valves inside the gatehouse, which are not performing as designed in 1848. Installation of a coffer dam should be complete today, which will allow access to the valves. The coffer dam is being constructed out of large and small sandbags which are being placed by divers. The dewatering also allows access for repointing the mortared joints in the stone armature inside the basin, which is underway. After this work is complete the Reservoir will again be filled to its original water elevation.
- Fish in the Reservoir - People have expressed concern about the fish in the Reservoir given the dewatering. The Project Engineer for the Town has been on site every work day and has been observing the fish. To date he has counted eleven dead fish, most of which were crappies which can die at this time of year after they have spawned. He has also been in contact with the Massachusetts Division of Fisheries and Wildlife, which did not restock the Reservoir this year per the Town’s request in anticipation of construction but will resume restocking after construction is complete.
- Gatehouse Interior - Selective demolition inside the gatehouse is approximately 75% complete, including removal of debris from the valves and removal of temporary bracing that had been installed as part of a previous roof project which was completed approximately two years ago.
- Gatehouse Exterior- Improvements are being made to the exterior of the gatehouse as part of a separate contract and funded in part by the Massachusetts Preservation Projects Fund administered by the Massachusetts Historical Commission. Overall cleaning of the building is almost complete, the mortared joints have been cleaned and repointed, new doors are being fabricated, and window grates have been removed for cleaning.
- Next Steps for the Rest of June and Into July - The Town’s Forestry crew will be removing additional trees very shortly. These consist of a Norway Maple which has grown into and damaged an abutter’s fence, and several trees at the Lee Street side of the park which have extensive decay and pose a safety hazard as determined by the Town’s Arborist. When the coffer dam is completely in place, work will begin on the valve improvements and building out the slope where the existing stone dust path runs along the gatehouse in order to make it wider and eliminate the current pinch point.
- Budget and Funding - The project is valued at $3.1 million and is funded by $2.2 million in capital funding, $500,000 in stormwater/drain infrastructure funding and $400,000 from the Commonwealth of Massachusetts’ Executive Office of Energy & Environmental Affairs Dam and Seawall Repair or Removal Program in addition to the Massachusetts Preservation Project Fund mentioned above.
- Schedule - Work is expected to be complete and the park reopened in the spring of 2020.
Construction Improvements Have Begun at Brookline Reservoir Park
Construction has begun at the Brookline Reservoir Park and Gatehouse. The Reservoir and Gatehouse, built in 1848 as part of Boston’s first municipal water system, is used by the entire Brookline community and beyond for walking, running, fishing, and passive enjoyment of this unique and historic resource. The project is valued at 3.1M and is funded by 2.2M in capital funding, $500,000 in stormwater/drain infrastructure funding and $400,000 from the Commonwealth of Massachusetts’ Executive Office of Energy & Environmental Affairs Dam and Seawall Repair or Removal Program. Brookline was fortunate to be selected for grant funding to attend to important infrastructure repair of the Brookline Reservoir dam and flood control structures. In addition, the Town received a $50,000 grant from the Massachusetts Preservation Projects Fund (MPPF) Round 24 to make improvements to the exterior of the Reservoir Gatehouse. The MPPF is a state-funded 50% reimbursable matching grant program established to support the preservation of properties listed in the State Register of Historic Places, and it is administered by the Secretary of the Commonwealth William Francis Galvin and the Massachusetts Historical Commission. The park and gatehouse improvements comprise a unique project in the Town given its many layers, and the key goals have been the following:
- Historic preservation, including stabilization and exterior restoration of the gatehouse;
- Dam stabilization and compliance with the Commonwealth of Massachusetts Office of Dam Safety’s (ODS) regulations;
- Utility upgrades and valve improvements for emergency controls at the gatehouse;
- Park improvements, the reconstruction of the stone dust walking path around the reservoir and widening the path at the current pinch point on the water side of the gatehouse, new ornamental safety fencing along the top of the dam, improved and accessible entrances, storm water management, removal of both aquatic and upland invasive plant species, and new plantings;
- Masonry repair to the reservoir basin and retaining walls;
- Addition of a restroom inside the gatehouse; and
- Replacement of the existing bus shelter on Boylston Street/Route 9.
It is important to highlight that a multi-year, parallel process was undertaken with the Office of Dam Safety (ODS), initiated by a directive per the regulations to remove all trees and shrubs on top of the dam and plant the area with grasses that could be mowed periodically to allow for visual inspection. This is the standard treatment for dams across the state, the intent being to maximize structural stability that could be compromised by uprooted trees, penetrating roots, and burrowing animals. The relationship of the dam to the surrounding densely populated area and the topography means that, although the ODS considers the dam to be well maintained, the risk of loss of life and property should the dam fail could be very significant. The Parks and Open Space Division worked with the ODS to develop an alternative plan that ensured the integrity of the dam while maintaining some trees on the dam, particularly Cherry trees, located above the water elevation. This plan involved a survey of the existing vegetation, a series of meetings and site visits with Town staff including the Town Arborist, ODS staff, and engineering consultants retained by the Town who specialize in dam improvements, plus development of a Tree Management Plan and a commitment to regular inspections. The changes proposed, especially the tree removals on the dam which is located on either side of the gatehouse and occupies approximately 40% of the reservoir’s perimeter, while necessary, will be a profound change to the visual character of the park.
The Park will remain closed during construction for safety reasons. Work on the exterior of the gatehouse has begun, installation of construction fencing and gates is complete, and we are currently working on drawing down the water in the basin to allow access to the valves and masonry, vegetation removal, and installation of a coffer dam at the gatehouse. Work is expected to be completed by the end of the 2020 construction season. You can follow the construction progress by visiting the Town’s website at this web site, https://www.brooklinema.gov/1408/Brookline-Reservoir-Park or contacting Annie Blair, Landscape Architect with the Parks and Open Space Division, Department of Public Works, by phone at (617)730-2616, or by email at [email protected].
The bid package for the park improvements has been completed and is currently available to contractors. Bids are due on March 19th, and an encouraging number of contractors have indicated interest. Once a successful low bidder has been established, the contract will be awarded and executed by the Select Board, and we hope to begin construction as soon as weather permits this spring. In the meantime, the Office of Dam Safety is reviewing the proposed work and we are engaging in a dialogue with them about work on top of the dam structure. The majority of the utility work and valve repairs are being included in the park improvements contract.
There are two separate contracts for work at the Gatehouse itself, one for exterior improvements consisting of repointing the granite and window and door replacement, and one to construct the gender-neutral restroom inside the Gatehouse. The successful bid for the exterior improvements came in below budget, which will allow us to increase the scope, and the low bidder is a contractor who has done good work for us in the past. Architectural design for the interior work is approaching completion and is incorporating comments from the Preservation Commission, which has been reviewing the work along the way. The exterior work will take place first and should be complete by the end of June. Interior work will happen after the utility and valve improvements have been made
After four public Design Review Committee meetings, the Park and Recreation Commission voted approval of the park’s landscape preliminary design, its scope and budget, and the base contract with add alternates. The proposed site work for the park is under review by the dam and geotechnical consultant team, and then will go to the ODS for their review and comment. We hope to issue a site construction package for bidding in 2019.
Outside of the park’s landscape improvements, the Gatehouse is also in need of a number of improvements:
- Addition of a gender-neutral restroom inside the Gatehouse
- Replacement of doors and windows at the Gatehouse
- Repair or replacement of historic valves within the Gatehouse
- Utility upgrades including water, sewer, and electrical at the Gatehouse
Separate efforts are underway to address the construction of the restroom in the Gatehouse and its attendant utilities, and the valve repairs. While the park plans are under review, we are acquiring additional necessary survey and utility information for conditions below the water at the Gatehouse and the architectural design is proceeding.
Brookline Reservoir Park is a 32 acre park surrounding a man-made body of water approximately one mile in circumference. The Reservoir was completed in 1848 as the terminus of the Cochituate Aqueduct, Boston’s first public water supply. Its key architectural feature is the Lower Gatehouse, an elegant granite structure. The park’s recreational and landscape features include a stone dust walking path around the perimeter of the water basin, a series of entrances into the park, over sixty memorial benches, signature flowering Kwanzan Cherry trees, and a mix of mature woodland trees, primarily deciduous. There are some open lawn areas used for passive recreation. The park is a destination for Brookline residents from all neighborhoods in the town as well as visitors from other communities. The park is listed on the State and National Registers of Historic Places, and was declared a National Historic Site.
The park is in need of a number of landscape site improvements:
- Universal access
- Masonry repair at the interior of the basin and at the Gatehouse
- Turf and planting renovation
- Renovation of the walking paths, including a solution for a “pinch point” at the Gatehouse on the water side
- Drainage and stormwater management improvements
- Removal of invasive plant materials
In addition, the Massachusetts Department of Conservation and Recreation’s Office of Dam Safety (ODS) is requesting the removal of vegetation on top of the dam structure itself in order to prevent potential dam failure due to downed trees and burrowing animals, and allow regular visual inspections of the dam’s condition. The Town has engaged the services of a dam and geotechnical engineering firm to aid us in conversations with the ODS about the ultimate impact on the park’s character.
The project’s goals prioritize maintaining the park’s character while addressing the necessary improvements.
