Ponds of Ballantrae Part 1 of 2: The Report Prepared by the Ballantrae Community Development District Board of Supervisors September 2013
CDD Board implements pond management plan This two-page plan lays out the Ballantrae Community Development District (CDD) Board of Supervisors management and maintenance plan for the 37 lakes and ponds within the community. The Board s primary goals via this pond management plan are to [1] prevent flooding onto our streets and into our homes, [2] provide a positive habitat for fish and wildlife, [3] maintain the good health of our pond water, beds and shorelines, [4] properly operate our outflow units and [5] ensure the high quality of our storm water entering the regional watershed. The Board decided in 2012 that it should commit to writing its plans for the management and maintenance of lakes and ponds just as it has a detailed, written plan for the management of the community s 80-plus acres of mowed lawns and landscaping, The Board noted Ballantrae s natural resources are extensive: more than half the community s 436 acres consist of lakes and ponds plus wetlands and conservation areas. The Board obtained pond-by-pond management input from its district manager, engineer and pond maintenance vendor. The Board took the extra step of notifying residents, via the January-March 2013 edition of the Communicator newsletter, that it had posted that information in a draft pond report on the CDD website (ballantraecdd.org). The Board invited resident comment by Jan. 31, 2013. The Board considered all that input in its public discussions leading to this plan. Several vendors then spent months bringing most of the ponds up to the levels presented herein. Final, minor work on one pond (#4) and six littoral shelves (#s 7, 11, 17, 18, 28 and 31) await the dropping of water levels during the dry season. The remaining work is described on pages here for each of those seven ponds. This plan provides our district manager, engineer and pond vendor with pond management direction. It also provides residents with useful information on the pond(s) in their neighborhood and throughout the community. Key to this plan is the Board s decision to manage the species, extent and location of plants in each pond. The Board wants to restrict the areas of plant growths to help maintain the openness of ponds. That decision will advance several environmental goals, including: Planting beneficials by hand. Littoral shelves are raised areas in 17 otherwise deeper ponds. The shelves are designed to elevate beneficial plants to ensure they can grow above a pond s high ground water level. These plants also help clean water. Format for this report This pond plan consists of two parts. Both are posted at the Pond Management tab at the CDD website at ballantraecdd.org: This Report begins with a two-page management plan, that also includes: A map on page 4 that numbers and locates each of our 37 ponds. The next 37 pages generally describe the species, extent and location of plants desired in each pond in numerical order. The second part of this plan is The Aerials: Its 12 photos show the extent and location of plants after most pond clean up was completed, establishing a baseline for future pond management. For those viewing on line: The pond list adjacent to the map in this Report is linked to the page discussing each pond. The pond list adjacent to the map in The Aerials is linked to the zoomable aerial showing that pond. Factors the Board considered included, among others, the surface area size of each pond, its depth, the presence or absence of a littoral The beneficial vegetation planted on pond slopes (called aquascaping ) helps to reduce erosion, treat runoff from adjoining properties and help clean pond water by the oxygen that plants release into the water. Mechanical removal of invasive plants.
shelf, plus the extent and species of plant growth. The Board also adopted best practices for pond management. For more information on proper pond management, see the Southwest Florida Water Management District (SWFWMD) pamphlet, Stormwater Systems in Your Neighborhood, posted at the CDD s ballantraecdd.org website at the CDD Operations tab at Other Documents. Here s a quick summary on how changing water levels affect plants in many Florida ponds: Aquatic plants generally survive in water depths of three feet or less. When pond depths fall substantially below three feet during the dry season, plants grow and thrive on shorelines and pond bottoms. That can result in as much as a 12-16 foot zone of plant material along some pond shorelines. Plants begin to die in the rainy season as water depth exceeds three feet in many of our ponds. That kills some of the plants along shorelines and pond bottoms that grew in shallow waters during the dry season. The Board doesn t usually remove excessive plant growth during the dry season, since the rise in water levels in the rainy season may eliminate it without cost to landowners. SWFWMD also allows ponds to be dug as shallow as only 12 inches below the seasonal high groundwater level. Natural plant growth could eventually cover the entire surface of some of these very shallow ponds. That s because their water level never rises above the three-foot depth necessary to kill any plants. The Board will remove excessive plants from the shallowest of these ponds behind residences. The Board allows plants to grow in some shallow ponds in non-residential areas (such as along Ballantrae and Mentmore boulevards). The Board believes excessive, nuisance or invasive plants Hand-pulling thick-growing beneficial plants to be transplanted elsewhere. are best managed by mechanical means, either via hand-pulling or machine-cutting and removal. The Board minimizes the use of chemicals to control plant growth, due to the long-term damage chemicals can do to pond waters and any desirable plant life or habitat in them. By law, pond management costs are shared by all landowners because the ponds [1] benefit all residents and [2] are the CDD s property and responsibility. In the 2012-13 fiscal year, the CDD s contract for a pond maintenance vendor totals $22,800, with another $30,000 available for lake/pond repairs plus $11,000 to purchase and install aquatic plants. Those appropriations paid the cost of the pond work detailed in this report. Many of the minor improvements at more than two dozen ponds were accomplished within the pond maintenance contract at no additional cost to landowners. Standard maintenance of all ponds continues to include, among other things, mowing banks and slopes, removal of certain excessive and invasive plants, treatment of algae and other nuisance surface vegetation, while monitoring pond conditions for any other needed treatment. It also includes maintaining the openness of outflow structures in 22 ponds. They foster the flow of water among ponds and the wetlands and facilitate seepage into the aquifer. Installing an aerator to help clean up a pond. Hand removal of tall, invasive plants.

Pond # 1 Village/Street: Ballantrae Blvd. Location: Small pond on SE side @ SR 54 entrance View (single photo) above is a general view, #2 is N-S shore while #3 is E-W. (stormwater system) Pond 1 outflows to Pond 33. Due to occasional high water levels in Pond 33, the outflow weir can be under as much as 18 inches of water. This results in a water backup that temporarily prevents the landscape maintenance vendor from mowing the wet slope areas, or to plant an expansion of the aquatic plants into the wet area. Some pond areas overgrown with plants will see them die in this deeper water. (aquatic plantings) The shallow area along the eastern side is not a littoral shelf and, therefore, was not planted with Club Rush. Remaining perimeter is covered approximately 80% with Club Rush. Standard maintenance. Club Rush will fill in missing gaps over time. Do not recommend planting the shallow area with Club Rush. Approved.
Pond # 2 Village/Street: Ballantrae Blvd. Location: W main pond @ SR 54 entrance Panoramic (multiple photos) above, #2 shows varying width of grasses. Assessment (stormwater system) Pond 2 does not contain an outflow control structure; it drains, via overland flow, into the wetland system on the south end and then into a culvert crossing under SR 54. It is also connected to Pond 33 via a culvert crossing under Ballantrae Blvd. The pond water level is susceptible to the same water back up condition in Pond 1 resulting in mowing issues around the pond. (aquatic plantings) 70% of Club Rush that was planted is gone. This is probably due to wake tear (waves). It is being replanted with Pickerel Weed as it overgrows in other ponds. Standard maintenance, allow Club Rush to fill in gaps naturally. Needs more aquatic plants to replace those that did not survive. Some pickerelweed was re-planted from other ponds by the end of May. Plants being replanted here from overgrowth of plants elsewhere. Plantings to be done so that they do not compete with exisiting Club Rush. Normal maintenance.
Pond # 2A Village/Street: Ballantrae Blvd. Location: N of weir at NE corner of Pond #2 (stormwater system) Pond 2A outflows into Pond 2 and it is functioning as designed. (aquatic plantings) 3 large clumps of Club Rush remain, due to treatment of invasive Torpedo Grass. Pond becomes dry in the winter. Club Rush will eventually cover all of the pond. Allow Club Rush to grow naturally Pond vendor has targeted full treatment to remove Torpedo Grass, most of which was completed in May. Minus the Torpedo Grass, there is now less browning of remaining grasses that are being allowed to grow naturally. Do not plant Pickerel since it would be taken over by fast-growing and aggressive Club Rush. Photo #1 Approved.
Pond # 3 Village/Street: Straiton Location: SW of Straiton on CDD border Panoramic above, #2 and #3 show extent of flowering plants and lilies, without many invasive grasses. (stormwater system) Pond 3 has a weir connected to the wetland on the east side. The drainage systems and pond water levels are functioning as designed. The wetland drains through a ditch to the same wetland into which Pond 2 drains. (aquatic plantings)this pond was not planted with Club Rush. Entire perimeter has Pickerel Weed and Arrowhead. Northern end has Fragrant Lilies. Some invasive growth within the Pickerel on northern end. Standard maintenance Approved
Pond # 4 Village/Street: Straiton Location: Central pond Panoramic above and #2 shows extensive grasses. #3 shows growth surrounding control structure. (stormwater system) Pond 4 was constructed six feet shallower than designed outside the littoral shelf, located on the south side of the pond. That has resulted in a shallow pond that sustains plant expansion across the entire pond surface, rather than just on the shelf as designed. Pond 4 outflows into the same wetland as Pond 3. The designed littoral shelf needs planting. (aquatic plantings) Club Rush covered nearly 100% of the perimeter. There was excessive algae growth on the shelf. Club and Spike Rush will continue to grow toward the middle of the pond. American Ecosystems used a boat to treat interior of pond. Options were discussed such as manual removal of some of the rush, and installation of aerators in the pond. It was noted that this pond was constructed shallower than designed and could be completely consumed by the Club and Spike Rush. These pond slopes are very close to the townhome structures. It is difficult to control algae, possibly due to chemiclas used in lawn treatment. Discuss lawn treatment options with Straiton HOA. $2,897 was approved in February for the purchase and installation of aeration equipment, which was completed in March. $3,000 was also approved to lower pond level to facilitate the removal of excessive Club and Spike Rush on the south and southeast sides of this pond. Vendors later recommended that, with the aerators cleaning up the balance of the pond, rush removal can await dry season drop in pond levels to avoid the cost of partial de-watering. Spike Rush and excessive Club Rush will be removed and Pickerelweed will then be planted on the littoral shelf and slopes. Straiton landscape vendor confirms it does not use chemicals on lawns adjoining CDD pond bank. All approved, with continued normal maintenance.
Pond # 5 Village/Street: Ballantrae Blvd. Location: S of Straiton entrance View above is an overview of small pond, #2 shows extent of grasses. (stormwater system) Pond 5 is connected to the same wetland as Pond 4 and is functioning as designed. (aquatic plantings) Invasive Spike Rush is growing on the southern side. Club Rush was planted on the three other sides. Invasive Dollar Weed growing on top of the Spike Rush. Keep the Southern end free of plants for the outflow structure. Floating surface vegetation is a nuisance and will be removed There are no residences near this pond. Grasses will be allowed to grow naturally in this pond. Otherwise, normal maintenance as needed.
Pond # 6 Village/Street: Straiton Location: NW of Straiton on CDD border Panoramic above, #2 shows scum and #3 extent of grass. (stormwater system) Pond 6 outflows into the wetland on the east side which outflows into Pond 4. It has a littoral shelf on the northeast side. Pond 6 is functioning as designed. (aquatic plantings) 100% of planted Club Rush remains. Some Dollar Weed is growing on the interior side of the Club Rush. Club Rush will eventually cover close to 100% of the pond. Standard maintenance Keep outflow free of vegetation Littoral shelf needs more plants. Approved without additional planting, with expectation that naturally-occuring vegetation will continue to spread across the littoral shelf.
Pond # 7 Village/Street: Ballantrae Blvd. Location: W side, across from Ayrshire entrance Panoramic above, #2 shows open area and #3 shows varying depths of grasses, plants. (stormwater system) Pond 7 outflows into the wetland on the west side and is functioning as designed. It has a littoral shelf on the northwest side. (aquatic plantings) Two sections of Club Rush have been removed to create fishing areas. The rest of the perimeter is covered with Club Rush and Pickerel Weed. Keep the open fishing access areas open. Littoral shelf needs planting. Standard maintenance. Approved, with expectation that naturally-occuring vegetation will continue to expand on littoral shelf. The Board in April approved the purchase of a total of 2,375 Pickerelweed plants at $1 each to be apportioned among the littoral shelves in Ponds # 7, 11, 17, 18, 28 and 31. All six shelves to be planted when water levels fall.
Pond # 8 Village/Street: Mentmore Blvd. Location:Across Mentmore Blvd. from clubhouse View above shows plantings dwarfed by grasses, #2 shows new grass growth, #3 open end of pond. (stormwater system) Pond 8 outflows into the wetland on the pond s south side and is functioning as designed. It has a littoral shelf on the northeast side. (aquatic plantings) Close to 100% of Club Rush remains. The littoral shelf has now been planted with Pickerel Weed. Small amount of algae are growing on the shelf. Allow the Pickerel Weed to grow. Keep the Club Rush from encroaching further across the pond and kill the algae. Algae has been treated with chemicals and being monitored for reappearance. Littoral shelf is deep enough that Pickerel growth should prevent expansion of Club Rush. If water levels do not allow that to occur, vendor will chemically control Club Rush.
Pond # 9 Village/Street: Mentmore Blvd. Location: W of clubhouse, N side of Mentmore Blvd. Panoramic above, #2 and #3 show extensive grass growth. (stormwater system) Pond 9 outflows into the abutting wetland which drains south through a culvert crossing under Mentmore Blvd. This pond is functioning as designed. (aquatic plantings) Close to 100% of planted Club Rush remains. Recently planted Pickerel Weed is doing great. Standard maintenance, Club Rush to be chemically treated as needed to control growth. Algae treated with chemicals and being monitored for reappearance. Littoral shelf is deep enough that Pickerel growth should prevent expansion of Club Rush. If water levels do not allow that to occur, vendor will chemically control Club Rush.
Pond # 10 Village/Street: Mentmore Blvd. Location: N side at W end of CDD property View above is an overview, #2 shows west side and #3 east side of pond. (stormwater system) Pond 10 outflows into the same wetland as Pond 9 and is functioning as designed. (aquatic plantings) 100% of perimeter is covered with Club Rush. Pond is clear of algae Standard maintenance. Approved.
Pond # 11 Village/Street: Lintower Location: N of Lintower Panoramic shows beneficial plantings as major growth around pond. (stormwater system) Pond 11 outflows off site to the northwest and is functioning as designed. It has a littoral shelf on the north side. (aquatic plantings) No signs that Club Rush was planted. Small areas of existing Pickerel Weed, small amounts of algae on shoreline. Littoral shelf has not been planted. Plant additional Pickerel Weed on shoreline. Littoral shelf needs planting with Pickerel. Littoral shelf and pond slope abutting homes to be planted with Pickerel. The Board in April approved the purchase of a total of 2,375 Pickerelweed plants at $1 each to be apportioned among the littoral shelves in Ponds # 7, 11, 17, 18, 28, and 31 when water levels fall.
Pond # 12 Village/Street: Cunningham Location: Along N&W borders of Cunningham View above is from S end looking N, #2 is from Ballantrae Blvd. looking W, #3 is from N end looking S. (stormwater system) Pond 12 outflows off site to the northwest and is function as designed. (aquatic plantings) It has a littoral shelf on the south side. Littoral shelf was recently planted with Pickerel Weed. Its abutting slope contains no fast-growing Club Rush, which tends to crowd out flowering Pickerel. So the littoral shelf should remain in its existing condition for natural expansion of the Pickerel. However, the fast-growing Club Rush on the east side of the pond will eventually takeover this narrow but long pond. Remove Club Rush on the eastern side. Replace with Pickerel. Approved: Mechanically cut and remove Club Rush on eastern side. Plant Pickerel as well as sodding along top of pond bank and slope to prevent erosion. Project cost $9,324, completed in August. Photo #4
Pond # 13 Village/Street: Ballantrae Blvd. Location: NE border of Ballantrae Blvd. @ Castleway Panoramic view of pond showing growth mostly at S end. (stormwater system) Pond 13 receives drainage from the abutting wetland and drains west through a culvert crossing under Ballantrae Blvd into Pond 12. This pond is functioning as designed, but a portion of the weir has washed out. The exact extent of damage is unknown. (aquatic plantings) Southern end has small gaps of missing Club Rush. This is a deep pond, so Club Rush should only stay on the perimeter. Weir repairs awaited a drop in water levels. Some repair work was completed to the exposed section of the weir in late May at a cost of $10,793.16. Funds were allocated from the $25,000 set aside in October 2011 for repairs to this weir in the Asset Reserve Fund, which finances on-going capital construction and repairs. The weir will be monitored to determine if future work is needed to maintain the structure. If so, repairs will be financed under this Asset Reserve Fund appropriation. Standard maintenance. Approved
Pond # 14 Village/Street: Castleway Location: Central pond Panoramic above, #2 shows rows of grass off shore from beneficial plantings. (stormwater system) Pond 14 outfalls to the abutting wetland which outfalls west into the wetland that drains through Pond 13 and it is functioning as designed. (aquatic plantings) Pond does not appear to have been planted with Club Rush. Most of perimeter has juvenile Pickerel Weed. Monitor the growth of the Pickerel Weed to determine if additional should be planted when water level recedes. Approved.
Pond # 15 Village/Street: Castleway Location: N central Castleway, W of Duke Firth View above and #2 show varying degree of pond growth, scum. (stormwater system) Pond 15 outflows into the abutting wetland which drains into Pond 13. This pond is functioning as designed. (aquatic plantings) Eastern side of pond has lost most of the planted Club Rush, so Pickerel Weed has been planted on the perimeter. Allow the existing Pickerel Weed to grow. Standard maintenance. Approved
Pond # 16 Village/Street: Castleway Location: S of Souter Lane Panoramic shows nice beneficial growth on far shore, #2 shows nuisance shrubbery growing on residential shoreline. (stormwater system) Pond 16 outflows into the abutting wetland and drains north through a culvert crossing under Duke Firth Street into the wetland that discharges into Pond 13. It has a littoral shelf on the south central side. This pond is functioning as designed. (aquatic plantings) Most of pond is covered with Club Rush and Pickerel Weed. Some invasive plants started to grow on the southern end. Remove the invasive growth along the pond bank Standard maintenance. Approved, invasive growth has been removed. Normal maintenance.
Pond # 17 Village/Street: Braemar Location: NE of Braemar village Panoramic view shows little grass or beneficial growth. (stormwater system) Pond 17 outflows into the abutting wetland and is functioning as designed. It has a littoral shelf on the northwest side. (aquatic plantings) Doesn t appear it was planted with Club Rush. Juvenile Pickerel Weed is growing on the southern and western sides. Monitor the growth of the Pickerel Weed, standard maintenance. Littoral shelf needs planting. Approved, transfer and replanting of plants underway from other ponds with excessive plants. The Board in April approved the purchase of a total of 2,375 Pickerelweed plants at $1 each to be apportioned among the littoral shelves in Ponds # 7, 11, 17, 18, 28, and 31 when water levels fall.
Pond # 18 Village/Street: Braemar Location: N of Braemar village Panoramic view looks S to narrow neck, where #2 shows substantial grass growth. (stormwater system) Pond 18 outflows into the abutting wetland and is functioning as designed. It has a littoral shelf on the northeast side. (aquatic plantings) Small coverage of Pickerel Weed on the perimeter. Some Torpedo Grass has grown within the Pickerel, which has been treated to kill Torpedo Grass. Standard maintenance. Monitor Pickerel Weed growth to determine if more should be planted. Approved. The Board in April approved the purchase of a total of 2,375 Pickerelweed plants at $1 each to be apportioned among the littoral shelves in Ponds # 7, 11, 17, 18, 28, and 31 when water levels fall. Some brown/dying Torpedo Grass has also been removed, reducing browning among the Pickerel Weed.
Pond # 19 Village/Street: Braemar Location: Central pond View above shows varying degrees of grass growth, all three photos show beneficial plantings being choked by grasses. (stormwater system) Pond 19 outflows into the wetland west of the pond, and is functioning as designed. (aquatic plantings) Entire perimeter is covered with Club Rush and Pickerel Weed. Chemically maintain Club Rush and prevent it from encroaching into the deeper middle. It was noted that this pond did not contain a littoral shelf. This pond is deeper than many of the community ponds. That depth should naturally restrict the expansion of the Club Rush. In fact, amount of Club Rush has declined as water levels rose this summer. Approved, monitor and chemically treat any further expansion of Club Rush in this pond.
Pond # 20 Village/Street: Braemar Location: W of Barnweill St. Views above shows overgrowth of plants and grasses covering more than 90 percent of this pond. (stormwater system) Pond 20 outflows into the abutting wetland and is functioning as designed. It has a littoral shelf on the north side. (aquatic plantings ) Large amount of Pickerel Weed covers the pond. Hundreds of Pickerel Weed plants have been removed and transplanted to other ponds. Spike Rush and other invasives are beginning to grow alongside Pickerel where they were not removed completely. This pond is very shallow and parts will go dry in winter. It was noted that this pond, due to its size, is shallow and needs to be monitored so that it is not consumed by Pickerelweed. Remove vegetation manually south of the littoral shelf and transplant the material to the littoral shelves needing plants. Approved. Remove extensive dead plants along shoreline and south pond bed. Pickerel will be transplanted to Pond #2 and Galleon will be added thereafter to treat /remove Spike Rush. All work completed in May, with substantial amount of Pickerel Weed removed and transplanted to Pond 2. Continue to transplant excessive Pickerel from this pond to others needing more. There has been rapid reemergence of nuisance plants in south 60+ feet of pond that were not fully removed in May (). Plants to be removed before they grow and expand to re-clog the pond. Pickerelweed can again be transplanted elsewhere.
Pond # 21 Village/Street: Braemar Location: NW of Barnweill-Glenapp intersection Panoramic shows most of pond covered in grasses, while #2 shows beneficial plants being crowded out by grasses. (stormwater system) Pond 21 outflows into the abutting wetland and is functioning as designed. It has a littoral shelf on the north side. (aquatic plantings) North, east and west sides were planted with Club Rush. Pre-existing Pickerel Weed mixed within the Club Rush. The southern end was either not planted or it has lost the Club Rush. Littoral shelf is half the pond. Plant Pickerel on the shelf pond perimeter. Mechanically-remove the club rush on the eastern side of the pond, repair sod damaged between homes and around pond during removal. Approved. Project completed in July at a cost of $3,572.
Pond # 22 Village/Street: Ballantrae Blvd. Location: S of Castleway entrance Panoramic shows covered S end of pond, #2 shows open N end. (stormwater system) Pond 22 outflows into the abutting wetland and is functioning as designed. It has a littoral shelf on the south side. (aquatic plantings) Perimeter is completely full with Club Rush. Pickerel Weed is on the littoral shelf. Some cattail growth has started on the shelf. Hand pull the cattails. Standard maintenance. Approved. Cattails have been removed.
Pond # 23 Village/Street: Ballantrae Blvd. Location: N of Braemar entrance Panoramic shows varying degrees of grass growth surrounding beneficial plantings. (stormwater system) Pond 23 outflows into the abutting wetland and is functioning as designed. It has a littoral shelf on the east central side. (aquatic plantings) Entire perimeter is covered with planted Club Rush. Some pre-existing Pickerel Weed is growing within the Club Rush Standard maintenance Approved
Pond # 24 Village/Street: Mentmore Blvd. Location: S of Braemar This view shows most of the pond is open, but #2 shows thick grass extending from the east end of the pond. (stormwater system) Pond 24 outflows into the abutting wetland and is functioning as designed. (aquatic plantings) Entire perimeter is covered with planted Club Rush. Some shoreline Torpedo Grass has grown within the Club Rush. Standard maintenance after removal of some Torpedo Grass. Approved. Torpedo Grass has been sprayed, which has reduced browning by other surviving species.
Pond # 25 Village/Street: Mentmore Blvd. Location: S side at E end of CDD property View above shows grasses hug shoreline, #2 shows structure that needs to be cleaned out. (stormwater system) Pond 25 outflows south into the abutting wetland and is functioning as designed. It has a littoral shelf on the south central side. (aquatic plantings) Perimeter of pond is covered with planted Club Rush. The Club Rush on the western side is not maturing as quickly as the rest, probably due to poor soil conditions. The weir structures have growth in front and needs to be cleared. Because this is a deep pond, Club Rush should stay only on the perimeter. Treat the growth in front of the weirs. Standard maintenance. Approved. Weir has been cleared.
Pond # 26 Village/Street: Ayrshire Location: N central horseshoe-shaped pond View above shows beneficial plantings but little grass growth, although #2 shows more. (stormwater system) Pond 26 outflows into the abutting wetland and is functioning as designed. (aquatic plantings) Juvenile Pickerel Weed on the perimeter, small algae growth in the interior of the pond. Monitor the growth of the Pickerel Weed, treat for the algae. Approved. Algae has been treated, monitoring is on-going.
Pond # 27 Village/Street: Ballantrae Blvd. Location: N of school property View above and #2 show most of pond surface covered in grasses, #3 is supposed to detail thickness. (stormwater system) Pond 27 outflows into the abutting wetland and is functioning as designed. (aquatic plantings) Nearly 100% of this small shallow pond is covered with Club Rush. It will eventually cover 100%. Remove the internal Club Rush mechanically. It was noted that this pond, due to its shallow depth, could become completely consumed by the Club Rush. $$8,488.40 approved at June 3 Board meeting to remove Club Rush, plant Pickerall Weed and re-sod as necessary. Approved. Completed in July.
Pond # 28 Village/Street: Ayrshire Location: E. of Ayrshire Blvd. @ N stormwater structure View above shows open channel but it and #2 show varying depth of grasses. (stormwater system) Pond 28 outflows into the abutting wetland and drains south. It has a littoral shelf on the northeast central side. The pond is functioning as designed. (aquatic plantings) Most of perimeter is covered with planted Club Rush. Needs more plantings on littoral shelf. Add Pickerel to littoral shelf. Standard maintenance. Approved The Board in April approved the purchase of a total of 2,375 Pickerelweed plants at $1 each to be apportioned among the littoral shelves in Ponds # 7, 11, 17, 18, 28, and 31 when water levels fall.
Pond # 29 Village/Street: Ayrshire Location: Behind Cunningham Court Panoramic shows grasses growing on shelf, as #2 shows grass growing in control structure. (stormwater system) Pond 29 outflows into the abutting wetland. It has a littoral shelf on the west side. The pond is functioning as designed. (aquatic plantings) Most of the perimeter is covered with planted Club Rush. The littoral shelf in the southwest corner has a few Pickerel Weed plus algae growth on it. Control structure needs to be cleared of growth. Keep a 2-foot plant-free opening in front of the control structure. Option 1: Manually remove the Club Rush on the western end of littoral shelf and plant the shelf with Pickerel Weed. Option 2: Allow the Club Rush to continue to grow on and fill in the littoral shelf Board in June chose Option 2, allowing Club Rush to expand on the littoral shelf. Can add some Pickerel Weed if needed later. Also monitor to ensure cleared control structure remains open. Approved.
Pond # 30 Village/Street: Ayrshire Location: SE corner of Ayrshire/Downan Pt. intersection Photo above is a panoramic of what used to be an open pond to the east and south, now covered in grass except at center, #2, showing pond scum. (stormwater system) Pond 30 outflows into the abutting wetland and is functioning as designed. (aquatic plantings) Western end of pond is nearly 100% covered with planted Club Rush, algae growth within open water area. Substantial Arrowhead growth was also noted. Option 1: Allow Club Rush to fill in all of the pond on the Western end. Option 2: Manually remove the Club Rush and plant with Pickerel Weed Option 3: Allow Arrowhead to emerge as a predominant plant in this pond. Approved Option 3 as follows: As Arrowhead continues to grow in pond, its flowers will become a dominant part of the pond landscape. Landscaping vendor also needs to do more mowing around this pond to clean it up and to help define it. Board will review in the future to determine if this plan improves appearance as desired.
Pond # 31 Village/Street: Ayrshire Location: S central pond Photo panoramic above shows grasses fairly consistent in depth and type while the central pond is clear. (stormwater system) Pond 31 outflows into the abutting wetland and is functioning as designed. It has a littoral shelf on the south central side. (aquatic plantings) Most of the perimeter is covered with planted Club Rush Littoral shelf needs planting Standard maintenance Approved. The Board in April approved the purchase of a total of 2,375 Pickerelweed plants at $1 each to be apportioned among the littoral shelves in Ponds # 7, 11, 17, 18, 28, and 31 when water levels fall.

(stormwater system) Pond 32 outflows into the abutting wetland and into Pond 33. It is functioning as designed. Pond 32 is also the receiving sump for the large outfall structure that was repaired a few years ago. (aquatic plantings) Shallow pond is 75% covered with planted Club Rush.

Pond # 33 Village/Street: Ballantrae Blvd. Location: E main pond @ SR 54 entrance Photo above shows offshore grasses but no plantings, #2 shows underwater growth and #3 shows emergence of new grasses. (stormwater system) Pond 33 is connected by culvert crossings under Ballantrae Blvd. to Pond 2. The pedestrian sidewalk runs along the north side of this pond. The sidewalk is designed at an elevation lower than the 25-year design, high water level of this pond. As a result, pond water levels can rise enough to flood the adjoining property and sidewalk. Flooding has also sometimes resulted in an inability to maintain the grass along the sidewalk, as well as delaying the vendor s ability to control the expansion of aquatic plants. (aquatic plantings) North, east and west sides of pond have been planted with Pickerel Weed. Torpedo Grass, Spike Rush and other invasives are growing on the northern side. Standard maintenance as water level allows. Monitor the growth of the Pickerel Weed to add more where needed, and control expansion of invasives. Approved. Gaps in Club Rush are being planted with Pickerel Weed.
