ADJOURNMENT MINUTES OF THE PROCEEDINGS OF THE PARKS AND RECREATION COMMISSION CITY OF MOUNDS VIEW COUNTY OF RAMSEY STATE OF MINNESOTA August 16, 1990 Mounds View City Hall 6:30 p.m. CALL TO ORDER The meeting was called to order at 6:36 p.m. by Chairperson Burmeister. ROLL CALL Commissioners present: Burmeister, Long, Trettel, Stevenson, Starr and Silvis. Staff present: Director Saarion MINUTES A motion was made by Commissioner Silvis, seconded by Commissioner Long to approve the July 18, 1990 minutes as written. Motion passed: 5 ayes, 0 nayes. CHAIRPERSON'S REPORT Chairperson Burmeister reported on park development at Lakeside Park . He informed the Commission that peat material needed to be removed in one section of the pathway near the softball field and also the need for additional material for fill. GREENFIELD PARK The Commission members drove to Greenfield Park to observe the progress of the baseball field improvement project and to inspect the playground equipment. A resident notified the department of his concern regarding a cable rope on the play equipment at Greenfield. The cable rope is to be used as a monkey climb from pole to pole. Evidently, the resident's daughter, 9 years old, had used the rope as a high -wire and attempted to walk on the rope. She fell and bruised her tailbone. 1 As the Commission observed the play equipment, it was noted that the rope could be removed. It was noted that if the rope was lowered, it would attract the younger children, for which it is not designed. The height of the play equipment is designed to fit the motor skills and development of appropriate ages. Moving the rope would alter the equipment, thus altering the specifications of the manufacture's warranty. It was the Commissioner's request that staff contact Gametime to inquire about any other concerns regarding this apparatus and their recommendations. BOND REFERENDUM Commissioner Silvis reported the discussion of the Council and the ultimate decision to go with only the fire department's request. PUPPET WAGON Director Saarion informed the Commission of the need for a new puppet wagon. This item will be included in the Capital Parks Budget for 1991. Commissioner Stevenson commented that he heard from a resident that the puppet wagon performances were not as good as usual this year. Director Saarion replied that she had many positive remarks but also had a negative comment by a resident. The resident happened to be the same individual that had remarked to Commissioner Stevenson. Because of the discrepancy in comments, staff sent evaluation forms to summer playcenter participants. The great majority of the evaluations were received with positive comments regarding the puppet wagon. SILVER VIEW PARK Director Saarion informed the Commission that Councilmembers and Director Saarion were invited to the annual membership meeting of the Silver Lake Woods Homeowners Association to listen to their thoughts concerning the Silver View Park Improvement Plan. The meeting is Wednesday, September 5 at City Hall lower level. Commissioners are invited to attend. 2 PARKS MAINTENANCE Director Saarion reviewed the memo to Council regarding park maintenance. Basically staff requests that whoever has control of park maintenance should also have the responsibility. In the past, the Parks and REcreation Department had the responsibility, but no control regarding park maintenance. Since Public Works has control of park maintenance, it is suggested that Public Works also be given the responsibility for the operations budget and assume responsibility of the parks maintenance services. SECOND QUARTER DEPARTMENT REPORT Director Saarion reviewed the second quarter department report. The Commission had no questions or comments. "GYPSY" REVIEW Commissioner Silvis reported on the Mounds View Community Theater production of "Gypsy". The audience numbers were less than anticipated. The production will run in a budget deficit. However, the production was good and the audiences were well pleased with the show. ADJOURNMENT Commissioner Stevenson made a motion to adjourn the meeting, seconded by Commissioner Long. The motion passed: 5 ayes, 0 nayes.

It is staffs hope that the Council will decide on revisions to the plan as desired or as seen fit so that staff can insert the revisions to the plan as quickly as possible for final approval on September 24, 1990. MS/SL MEMO TO: MAYOR & COUNCILMEMBERS FROM: MARY SAARION, DIRECTOR - PARKS, RECREATION AND FORESTRY DATE: SEPTEMBER 12, 1990 SUBJECT: SYNOPSIS OF CONCERNS EXPRESSED BY THE MANOR HOMEOWNERS ASSOCIATION -,SEPTEMBER SEPTEMBER 5, 1990 On Wednesday, September 5, 1990, Councilmembers Blanchard, Paone and I attended the annual Silver Lake Woods Manor Homeowners Association meeting to listen to their concerns regarding the Silver View Park proposal. The membership agreed with the overall park concept plan as recommended in the proposal. Many of their specific concerns are addressed in the proposal including: I. WEEDS IN THE POND. They, too, agreed that week harvesting must begin as soon as possible and agreed that it i~ a top priority for the pond area as indicated in the proposal. 2. CONTROL OF POND FRINGE WOODY GROWTH_ The association is willing to offer volunteer services in a supervised and controlled activity of trimming woody brush from the pond fringe, understanding that a grassy buffer area around pond will remain to provide a filtering element for pond run-off and to help prevent pond penetration of trash and litter. 3. SCENIC VISTA AREAS. The membership agreed with the proposaPs recommendation of mowed scenic vista areas. 4. PATHWAY. The membership was unanimously in favor of continuing the pathway completely around the pond and agrees that it is a top priority. The membership was in opposition to three elements of the proposal. 1. HARD SURFACE PATHWAY ALONG NORTHSIDE OF POND PATHWAY. The membership unanimously agreed that a hard surface pathway will deteriorate the nature aspect of the pond area and invite dangers of fast-moving users on a walking path and detract wildlife in the pond area. 2. BRIDGE OVER THE NARROWS. The membership questions the need for a bridge across the narrows, expressing their thoughts that pathway users choose to walls for exercise and the pond pathway, if continued, is good enough. 3. EASEMENT CONNECTION TO LIBRARY. None of the homeowners wishes to have an easement between the manor homes. It was the opinion of the membership that when the sidewalk on Long Lake Road is finished, the connection of the pond path and Long Lake Road sidewalk will provide an adequate access avenue to the library. -2- 4. PARK LIGHTING. The membership reiterated their desire to have no lighting at = the park. {Lighting is not addressed or - 1 recommended in the proposal..) The membership requested that the City look into two special requests: 1. Spraying for ragweed and Canadian thistles and nettles. 2. The membership would like the City Engineer to check on the outlet flow at Long Lake Road. It was suggested that perhaps water flow has been hampered. The membership concluded that they were eager and willing to assist the City with volunteer services and requested expediency in these matters concerning Silver View Park.

The Commission recommends three modifications. One is the recommendation of a hard surface pathway on the north side of the pond from Long Lake Road to the picnic shelter. The second recommendation is the provision of two play structures, one in front of the picnic shelter specifically for pre-schoolers and one to the west of the picnic shelter, to be handicapped accessible and designed for 6-12 year olds. The third recommendation is to add sprinkling capabilities for future needs at the soccer field and picnic shelter area. The Commission unanimously and wholeheartedly approves the Silver View Park Improvement Plan, including these additions, and recommends adoption by the City Council, and requests implementation as soon as possible. Wayne Burmeister, Chairperson Frank Silvis, Commissioner David Long, Commissio r Pam Starr, Commis ' ner n Gary Stevenson, Commissioner Edd Trettel, Commissioner 4 printed on recycled paper INTRODUCTION On November 13, 1990; the City Council appointed seven residents to form the Silver View Park Task Force. This Task Force was commissioned to propose recommendations regarding an improvement plan for Silver View Park to serve as a plan for future improvements. Information received in the City survey by Decision Resources, Ltd. and the Silver View Park Pond Management Study, prepared by Environmental Specialists, was to be considered in the planning process. The plan was to include facility improvements, funding recommendations, and a schedule or time line for improvements to occur. The Task Force met as a group three times. The first meeting included these six items: 1. Reviewed the task of the committee. 2. Discussed the survey results regarding Silver View Park. 3. Reviewed the pond management study and Environmental Specialists recommendations. 4. Became familiar with the present park facility map. 5. Reviewed past improvement recommendations and costs. 6. Discussed options for a plan for Silver View Park improvements. The second meeting expanded on improvement ideas. The third meeting was to review the collection of ideas and concepts for the park and to finalize the written document. Minutes of these three meetings are provided in the appendix of this document. A joint meeting with the City Council, Parks and Recreation Commission and Task Force was held on May 7, 1990 to review the proposal. At the conclusion of the meeting, the Council requested that the entire Parks and Recreation Commission review the proposal and offer a recommendation. The Parks and Recreation Commission reviewed the proposal at their regular meeting on May 24, 1990 and upon inclusion of three changes, which are included in their letter of recommendation on page 4, unanimously recommended that the City Council approve the proposal. P SILVER VIEW PARK IMPROVEMENT PLAN PURPOSE STATEMENT It is intended that Silver View Park become a focal point of the community; a gathering place for friends and neighbors; a resource for passive leisure and a facility for active recreation. The Silver View Park Task Force recommends that the City continue to move forward in the provision of park improvements at Silver View Park. The following are thirteen recommendations for a plan of improvements at Silver View Park. These thirteen recommendations are supplemented with additional information given as a reference in the remaining portion of the proposal. I. CONCEPT PLAN It is recommended that Silver View Park should be divided into three concept areas. Each area should constitute a different function or "concept". The three areas and their functions are listed below in the description of the "Concept Plan". Concept #1 - Silver View Park Pond. This area includes the body of water and the pond buffer area. The function of this area is to provide the natural resources for a nature setting. Concept #2 - Nature/Passive Area. This area includes all the upland natural wooded areas of the western area of the park, and the pathway area around the pond. This area is predominantly for nature activities such as hiking and nature study. Concept #3 - Active Play/Social Area. This area includes the upper part of the park. This area is intended to provide play and social gathering facilities to accommodate people of all ages. This concept plan is important to understand because it was the basis of formulating many recommendations for issues regarding improvements to Silver View Park. The first concept or function area that was discussed was the pond area. The consensus of the group was to adopt the water quality recommendations presented by Environmental Specialists in their Silver View Pond Management Plan.

This includes the upland wooded area of the park located on the western side of the parking lot and the pathway area around the pond. This area is intended for passive activities such as hiking, cross country skiing, quiet contemplation, nature study and low-key picnicking. It is intended that this area resemble a wildlife habitat, to provide an inner-city forest, nature area. The intention is to attract many plant species and wildlife for observation and study. The rustic "state park", natural look is appropriate for this area. Active play facilities and activities should not infringe on the passive, nature area. Concept or function number three is the Active Area. This area is intended to provide facilities for people who want to participate in physical or social activity. The group's desire was to try to provide facilities for all age groups and to incorporate social activities as well as athletic and fitness facilities. The intention of this area is to encourage people to recreate by offering them the opportunity to use facilities. IT. PARK PRIORITIES The issue of priorities for park improvements was discussed. The group wishes to emphasize that priorities are not "set in stone" and should have flexibility to change when and as funding is available or as special requests are made for different improvements. The priority list and schedule is simply a guideline. It should be noted that the costs listed in this plan are 1990 estimates. Priorities may change and the schedule will probably be altered during annual budgeting to implement the funding opportunities in the future. III. FUNDING Funding was another issue discussed. It is understood by the entire Task Force that funding is the key to the implementation of the improvement plan. Since funding is parochial in the realm of this group, it is assumed that the City Council will deal with funding options as it relates to the entire city funding picture. Therefore, although suggestions have been given for funding sources, it is understood that the schedule will most likely be altered. The City will request donations from community organizations for capital improvements as indicated on the Silver View Park Improvement Plan - Capital Items (on page 11.) Other fundraising activities such as grant applications will be actively pursued by the City. Funding sources which were identified and recommended include: 1. PARK IMPROVEMENT FUND The Park Improvement Fund is one funding option. Through park dedication fees paid by Everest, LTD, the City receives $12,500 each year until 1995. A portion of these Silver View Park Improvements are proposed to be funded from this source. E7 2. DONATIONS It is hoped that the Mounds View Lions Club will be a local organization that is interested in "adopting" Silver View Park by funding improvements. 3. PARK DEPARTMENT BUDGET Construction projects can be budgeted in the annual park department fund with the condition that the projects are scheduled one year in advance. The $13,000 proposed for the culvert on the western inlet to the pond relies on funding from the Storm Water Management Fund. It is assumed that since the culvert would be an improvement to the storm water ditch and inlet that it may have the criteria necessary for using Storm Water Management funds. 4. BOND REFERENDUM One source of funding is not shown on the funding graph but is another option. That option is a specific bond referendum for improvements at Silver View Park. A bond referendum of $150,000 would cost a typical homeowner approximately $4.78 per year for ten years. A small successful bond issue would complete this improvement plan. IN. DONATIONS AND CQNTRIBUITDNS Donations and contributions by community organizations was another issue discussed, especially since donations and contributions provide over half the improvement funding. Therefore, the committee realizes the value and need for providing an open avenue to request funding for park improvements. The City will apply for donations as described in this plan. To facilitate willing donations, and grateful receiving of donations, the Task Force has suggested these guidelines. 1. Donations may provide the funding of improvements according to items on the priority list, or 2. If in -sufficient monies are available to fund the improvement, the donating group could choose one of two options. a. The City would retain the money until enough funds were accumulated to fund the priority. b. The group could choose another improvement in which the funds were sufficient. 3. Facilities improvements which are not included in this plan, but wish to be funded by the donating organization, must comply with the park concept plan and must be recommended by the Parks and Recreation Commission and approved by the City Council. 10 V. LIBRARY CONNECTION The City will pursue an access to the library from the park pond pathway considering feasibility, cost and easement agreement opportunities. VI. PARK PATHWAYS The issue of the pathway around the pond was discussed and resolved with unanimous agreement that the path should continue around the entire pond. It was also agreed that the path around the pond should remain a woodchip material to comply with the nature concept. Furthermore, it is the group's recommendation that the pathway be completed as soon as possible. An easement agreement is being prepared for the pathway connection along the Scotland Green Apartment Complex. The path will require narrowing at the easement access along 7405 Parkview Dr. At the time the pathway is completed, landscaping will be planned and planted to designate public versus private land along this pathway connection. A hard surface pathway is designated for the active area of the park and along the pathway following the north side of the pond. This path will connect the activity areas. The hard surface pathway will continue along the north side of the pond from Long Lake Road to the picnic shelter and connecting to Silver Lake Road with hopes for a future connecting access to the library. This hard surface pathway along the northern side of the pond will enable persons that are walking impaired with the opportunity to walk a portion of the nature path to the active area of the park and finally leading to the picnic shelter. The hard surface will enable bikes, skateboard, rollerblade, wheelchairs and stroller use. VIII. BRIDGES It is suggested that the bridge should be a pedestrian bridge rather than a bridge accommodating maintenance vehicles. With the installation of the culvert over the west inlet to the pond, the maintenance staff will have a vehicular passageway accessing the path. The opinion of the Task Force is that two vehicular passageways are not needed. The cost of the pedestrian bridge would be less than a vehicular bridge. This recommendation is contingent on the installation of the culvert over the west inlet to the pond. Two smaller bridges or culverts should be installed along the nature path. One must be installed in the gully area off of the Silver Lake Road access. Another must be installed in the area along Long Lake Road near the Scotland Green parking lot. These bridges or culverts are necessary because of water or ditch hazards on the pathway. 11 /-1 PLAN FOR PATHWAYS �l r 1 �t1LlrA"i�w_Aarlr � i ~� Burger King •~� SuperAmerica rI � 4- h 1p Sliver View Plaza Library (Elderly Housing) rWlldwood Manor ^ Sliver View Pond I. .

Specific direction such as placement of park amenities is not given but instead suggests that the Parks and Recreation Commission and City Council will determine such placement. IX PROCEDURE FOR AMENDMENT Procedures for the amendment of the Silver View Park Improvement Plan is as follows: 1. The Park and Recreation Commission must review any amendment to the plan. 2. The Council upon recommendation from the Parks and Recreation Commission will review the amendment. 3. A public hearing must be held. 4. Final approval by simple majority of the Council must be given by resolution. The criteria of any amendment is that it follows the concept plan described in this plan. X. AMPHITHEATER It is recommended that the amphitheater should be eliminated. The area should be re -sloped for a gentler grade so that it can be used for a variety of purposes including an outdoor, grassy entertainment area, performance space, or general multi-purpose greenspace. XI. PARK MA=NANCE PROPOSAL Guidelines for the maintenance of Silver View Park is included in the general Standards of Park Maintenance accepted by the City. Park maintenance duties included in the standards include pathway upkeep, litter pick-up, trash removal, sweeping the basketball court, raking the sand volleyball court, inspection, cleaning and repair of equipment and facilities as necessary, mowing grass, tending bushes and trees, maintaining the sprinkling system, and other duties as described for general park maintenance. Park improvement projects will be implemented by contracting services. It has been determined that a reasonable buffer area should be left unmowed around the pond while mowing as close to the pond as practical and mowing up to any wooded areas. Also, mowed areas in the wooded pathway areas should be mowed as wide as practical. 13 An annual activity with Silver View Park neighbors will be scheduled to rely on their assistance in trimming trees and brush within park property. This volunteer program will be supervised by staff to ensure control and uniformity in the maintenance of Silver View Park wooded areas and pond buffer area. XII. SPRINI{IMG SYSTEM EXPANSION For future turf maintenance and park beautification, it is important to water the grass to ensure healthy turf. The sprinkling system mechanics are already installed including a pump and electrical timer. The system was installed with the capabilities and expectations for future expansion to the soccer field and picric shelter area. The expansion cost would include be additional pipe, sprinkler heads and installation labor. M. CONCLUSION In conclusion, it is recommended that the City continue to move forward in the provision of park improvements at Silver View Park. It is intended that this park become a focal point of the community, a gathering place for friends and neighbors, a resource for passive leisure and a facility for active recreation. 14 ro ►-3 H rt 03 _l 01 Ul A.

Adeline suggested lighting the trail. Ron Fagerstrom suggested that after hours park use or curfew occurs at darkness and therefore, people should not be in the park after dark in the summertime. Dave Rademacher expressed his desire for the natural look. George Andres stated that an asphalt path would also be accessible for biking, skateboarding and rollerblades. Dave Rademacher expressed his opinion that this is a community park for residents, not a regional park for neighboring community users. Dave further stated that it was his opinion that some people don't like to walk the full path and would like to have a bridge available as a shortcut. Ron Margo restated the issue of asphalt attraction to bikers/bladers and skateboard users. David Rademacher suggested the two path system with a natural woodchip path around the pond and an asphalt path on the active upper area of the park. Adeline Lee expressed her opinion that the park will get more use now with the new picnic shelter, especially from the Senior Citizens. Dave Long suggested that facilities lacking in Silver View are for the young and the elderly. Dave Rademacher suggested that the bridge would connect the single family homes to the manor homes and gave an example of his daughter who missed the school bus could run across the frozen pond to get on the bus as it made its rounds on Mounds View Drive. George Andres stated that he uses the park all the time and sees more active users than passive. Ron Fagerstrom stated that he sees lots of hikers himself included. Adeline Lee asked about funding grants. Director Saarion explained that several grants had been submitted, that funding has been difficult to obtain because the past years of funding criteria has prioritized acquisition and water oriented projects, not development projects. Ron Margo stated that paved pathways could be plowed and used in the wintertime. Dave Rademacher suggested that maybe the kids wouldn't be so bad. Ron Margo told of examples of different paths in Minneapolis and their various uses. Ron Fagerstrom suggested that the group divide the planning into three phases; the pond, the nature area, and the active area. Adeline Lee asked about the likelihood of a nature center, naturalists, and nature walk. Ron Fagerstrom asked about the continuation of the path. David Long stated that he felt the path should be continued all the way around the pond. David Rademacher and Mary Saarion explained the history of when land was sold and sales personnel erroneously indicated to buyers that the park plan was definite rather than dependent upon the passage of the bond referendum. Therefore, property buyers were erroneously convinced that the park plan was set in stone and not subject to change. The plan showed the bridge at the narrows and did not indicate a connected pathway. The developer was to provide the bridge. However, the cost of the pond dredging became more costly, and the elimination of the bridge become the negotiated item. David Rademacher continued to state that the resident's around the pond are not opposed to the path, but rather the principal of purchasing land with an expectation that is changed. CE David Rademacher continued to say that the residents were opposed to the size and shape of the picnic shelter but like it now and want more smaller ones around. Security, a bridge and boardwalk for the bog are his concerns. It was stated that Environmental Specialists expressed concern regarding a boardwalk on the bog (as suggested in the original master plan) because that is the area where wildlife nest and breed. A boardwalk would be an intrusion forcing the wildlife away. Ron Fagerstrom suggested that more benches are needed. David Long suggested glider swings. Ron Fagerstrom agreed because they are used and enjoyed by all ages. Ron Fagerstrom again suggested that the group organize planning into three phases. Ron Margo referred to the survey and suggested that path completion and bridge are indicated as needs by the community. PHASE I OF PLANNING - WATER QUALITY: The first phase of the planning deals with water quality. Ron Fagerstrom suggested that we recommend to the City Council a resolution and request for compliance by the Silver View pond drainage area the reduction in use of phosphorous in fertilizers. After discussion, the group requested Director Saarion to ask City Council approval for requesting voluntary compliance for use of fertilizers without phosphorous as a means of maintaining water quality in the pond. The group also requested Director Saarion to look into costs of harvesting weeds with a chain/winch method. This group requests staff to use a substance for street plowing that does not harm water quality and asked for alternatives. Finally, the group requested information regarding development on County Road I to consider ponding uses/use for filtering and sedimentation as it may benefit the pond. PHASE II OF PLANNING - NATURAL AREA: It was suggested that as recommended by Environmental Specialists, a wood duck house should be placed at each arm of the pond. David Long asked Adeline if the Seniors would be interested in donating a bench. Adeline thought that they would. The group decided that the completion of the path should be the second priority. David Rademacher asked about alternatives for the inlet area which requires a culvert installation. Director Saarion stated that the Parks and Recreation Commission had originally requested a wooden foot bridge, but that public works requested vehicular passage for more efficient maintenance, resulting in the culvert design. 61 David Long requested that staff provide prices on a bituminous pathway on the north side of the park. The group thought that play equipment was a ,priority. Adeline Lee suggested that perhaps the Shriners or Masons would be interested in donating money for handicapped accessible facilities in the park. Director Saarion suggested that playground equipment may be an item which the Mounds View Lion's would be interested in funding. Director Saarion asked the group to consider a recommendation regarding acceptance of donations for items which are not on the priority list or which jump priorities. After discussion, it was decided that the group will recommendation that donations should be given without specification unless requested by the City for a specific item. The unspecified donations would be used for priority items. Ron Fagerstrom suggested that skating was a fun activity on the pond and asked if some facilities should be offered for this activity. After discussion, it was agreed that part of the skaters fun was clearing the ice, making benches, and nets and creating their own skating areas. George Andres brought up the idea of lighting the athletic fields. The group was against lighting athletic fields referring to the 10:00 p.m. curfew. After two hours, it was suggested that the meeting adjourn and next meeting date chosen. The next meeting will be held on Wednesday, April 4 at 7:00 p.m. ADJOURNMENT: Meet adjourned at 9:00 p.m. Respectfully submitted, Mary Saarion, Director Parks, Recreation and Forestry 62 r) SILVER VIEW PARK TASK FORCE 2ND MEETING APRIL 4, 1990 QUESTIONS FOR DISCISSION 1.

Ron Margo and George Andres were absent. DISCUSSION: Ron Fagerstrom wanted to further describe the pond buffer maintenance guidelines. A map was presented to provide an illustration of the buffer areas. The group reviewed each section of park improvements as discussed at the first meeting. Priorities for each section were reviewed as well as descriptions of improvements. Funding sources were reviewed and discussed. Issues were also discussed. These issues will be present in a narrative with a recommendation to Council regarding the Silver View Master Plan. The letter requesting residents to comply with use of low or no phosphorus fertilizers was distributed to residents of the Silver View drainage area and to Spring Lake and White Oak pond residents as requested by the City Council. Staffs list of issues were discussed and the committee recommendation for each is as follows: Question #1. What other alternatives are there for the amphitheater? Answer. There were several options discussed for the amphitheater, but it was unanimously agreed that it should remain just as is and permitted to let grow. At some time in the future, a purpose or improvement may be decided, but at present, it is a low priority and safety hazard for mowing. Consensus: Let grow and leave it alone for the time being. Question #2. What should the buffer area distance be from the pond? Answer. Environmental Specialists suggested that a larger buffer area would attract wildlife because it offers more nesting area. Also, the buffer provides a filtering service, trapping litter and contaminants before they enter the pond. 64 It was unanimously agreed upon by the committee that the buffer zone should be left to grow up to 1 - 2 feet from the pond side of the path. This 1 - 2 foot mowed area alongside of the trail would alleviate encroachment of weeds on the path. The buffer areas would be left alone except for areas indicated on the map which calls for large tree or bush pruning to offer pond vistas. Vista areas will be mowed. The overall guideline is that the weed growth buffer area between the pond and the pathway should be at least 8 - 12 feet. Furthermore, the south side of the sliding hill will be recommended to let grow to curb erosion and to provide a wildlife nesting area. Question #3. Who is to determine when it would be beneficial to the pond to perform weed harvesting? Answer. It was unanimously agreed by the committee that professional water biologists such as Environmental Specialists would be requested to periodically test the water and suggest appropriate action to maintain water quality. Question #4. The recommendation from this group regarding Silver View Park improvements are dependent upon funding just as the 1981 Master Plan was dependent upon funding. What will be the answer to community residents asking why scheduled improvements are not occurring; the reason being that monies are not appropriated as recommended. Answer. After discussion regarding the public's perception of a master plan, it was unanimously agreed upon by the group that a narrative must be presented as part of the plan to explain that the goals and priorities and funding sources are simply a plan and guide for future improvements. Furthermore, this plan can be changed, but the basic park concept plan should remain consistent. That concept plan offers three areas of the park. The first is the pond. The second is the nature area around the pond and the third is the active area. As long as future requested improvements follow the theme of these three areas of the park concept plan, the improvements should be considered. Question #5. How can this improvement plan remain flexible for special opportunities or needs which today are unforeseen such as grant opportunities, special donations, or requests for facilities that are not included in the master plan? Answer. It was unanimously agreed upon by the group that the master plan must have a clause allowing flexibility for future improvements that may be req.iested or opportunities for funding facilities as long as the improvements are compatible with the park concept plan. Question #6. The issue of pathway construction materials must be decided; asphalt, woodchip or combination. Is the group interested in the northern asphalt pathway addition, and if so, what is the priority? ;-v Answer. It was unanimously agreed upon by the group that the pathway around the pond should remain woodchips to follow the concept theme of nature trail. The construction of the pathway segments was a priority with the recommendation that construction begin as soon as possible, hopefully to be completed by October of 1990. The group also unanimously agreed that the active area of the concept plan should have an asphalt pathway that would provide a surface for bicyclists, skateboarders, rollerbladers, strollers and wheelchairs. This path would connect the active area facilities. Question „#7. Donations could be the greatest funding source for the majority of the improvements at Silver View Park. What recommendations can this group give to ensure that donations will be generously given and gratefully received to encourage an atmosphere of good will and community service by the donating organization and the City? Answer. It was unanimously agreed upon by the group that donations should not be rejected. Donations would be accepted under these circumstances: 1. If donations would provide the funding of improvements according to items on the priority list, or 2. If insufficient monies are available to fund the improvement the donating group could choose one of two options. a. The City would retain the money until enough funds were accumulated to fund the priority. b. The group could choose another improvement in which the funds were insufficient. 3. Facilities or improvements not on the master plan which wish to be funded by the donating organization must comply with the park concept plan and must be approved by the Parks and Recreation Commission and City Council. Staff was requested to provide information for the next Task Force meeting. The information would include prices and examples of playground equipment for pre- schoolers, handicapped users and elementary age children as well as exercise equipment to better plan a three stage funding process for the play equipment. Also, staff will prepare a narrative to accompany the master plan packet which explains the groups recommendations regarding the issues which were discussed. The next meeting to review the final packet was set for Monday, April 16, 1990 at 7:00 p.m. Meeting adjourned at 9:00 p.m. 1*9 I -i MINUTES OF THE PROCEEDINGS OF THE SILVER VIEW TASK FORCE CITY OF MOUNDS VIEW COUNTY OF RAMSEY STATE OF MINNESOTA CALL TO ORDER ROLL CALL Monday, April 16, 1990 Mounds View City Hall 7:00 p.m. Lower Level David Long, Deborah Ashworth, Adeline Lee, David Rademacher, George Andres, Ron Fagerstrom and Mary Saarion. PROPOSAL REVIEW The proposal was reviewed. The Task Force identified projects and issues to add to the proposal. These additions are described below. 1. Two path areas were identified as difficult to maneuver when wet. A bridge and culvert remedy was suggested. These pathway passageways will be added as improvements in the passive nature portion of the proposal. 2. The pond buffer area maintenance was discussed. Forester Wriskey conveyed his concern that the recommended map of the pond buffer maintenance plan is beyond labor capacity of the City presently. After discussion, it was requested by the Task Force that a recommendation be written to include a seasonal maintenance employee specifically for Silver View Park. 3. The Task Force would like to see an easement offering access for people living on the south side of the pond to the library. This easement would lie between the Manor Homes buildings. 4. The Task Force requested that a park concept map be added to define the park function areas. 67 5. It was also suggested that the mowers be supervised in mowing the pond area. 6. It was recommended that the triangular area between the Miller property and stand of trees be mowed 8-12 feet in a free -form manner. These recommendations will be added to the final proposal. The Task Force indicated confidence in the proposal (with the additions), and are prepared to present the proposal at the May 7 joint meeting. ADJOURNMENT Respectfully submitted, Mary Saarion, Director Parks, Recreation and Forestry :�: SILVER VIEW PARK POND MANAGEMENT STUDY The Silver View Park Pond Management Study is a document prepared by Environmental Specialists. This group of specialists provided information and recommendations regarding the future management of Silver View Park pond. The Silver View Park Task Force referred to this document as a resource for making recommendations of park improvements to Silver View Park. All of the Environmental Specialists recommendations were not offered in the Silver View Park Improvement Plan. For instance, the weed harvesting recommendation was implemented in the plan, but the expanded buffer areas with reduced mowing was not recommended in the final Silver View Park Improvement Plan. agement Study is included in the Silver View Park tion resource and document. SILVER VIEW POND MANAGEMENT PI nN Prepared for: CITY OF MOUNDS VIEW Prepared by: ��ENVIRONMENTAL SPECIALISTS 69 I. INTRODUCTION In response to neighborhood and city concerns regarding the management of Silver View Pond (Mounds View Wetland 893), the City of Mounds View commissioned the preparation of this study and management plan. In order to develop the appropriate scope for the management plan, a broad proposal for a study of a number of potential management objectives was prepared and presented to the Mounds View Parks and Recreation Commission and interested citizens. Four objectives were considered; 1) improved water quality, 2) wildlife habitat enhancement, 3) creation of a viable fishery, and 4) improved aesthetics. Based on the input received at this meeting, the Mounds View Park and Recreation Commission recommended and the City Council commissioned the development of a management plan which focused.on water quality and wildlife habitat value. II. PHYSICAL CHARACTERISTICS OF BASIN Silver View Pond is located approximately 1/4 mile south of Trunk Highway 10, between Long Lake Road and Siler Lake Road (Figure 1). The pond is 11.39 acres in size (excluding contiguous wetland) and has an average depth of about 4.0 feet; the distribution of depths within the basin is shown �:- in Figure 2. The normal surface elevation of the pond is 893.0 and is controlled by an outlet structure on the east end adjacent to Long Lake Road. Water discharging from the pond outlet flows about 1 mile to Rice Creek. The pond was created by excavation in 1982 to provide stormwater storage for developments proposed within its drainage area. The pond was designed to have three distinct arms or basins with narrow connections between each to retard the movement of sediment and nutrients toward the outlet. approximately 9.34 acres (82 percent) of the pond was originally wetland. The pond's dominant bottom substrate is sand with a thin layer of peat or muck. Several small areas of the pond are underlaid by deep peat or muck deposits which appear to be remnants of the original wetland soils. III. DRAINAGE AREA CHARACTERISTICS At the time that Silver View Pond was designed in 1982, its drainage area was estimated at 203 acres and included about 57 acres north of County Road I (from Revised Hydraulic Calculations, Oak Lake Park Ponding Area, Mounds View Minnesota; Sunde Engineering, Inc., March 31, 1982). Since that time the drainage area for the pond has been redefined to total about 145.7 acres (from _Mounds View t_ Minnesota Storm Water Drainage Analysis; Comstock and Davis, Inc., January 4, 1985). Based on the more recent figures and our field review of the drainage area, we have concluded that 70 Burger King SuperAmerlca 71 Silver View Plaza (Retail) �1,Wlldwood Manor (Elderly Housing) Area Boundary -- a!••.' -Outlet Structure �x • land Green Apartments 1 ^ _ U O fel f� t7unly 6atl H'2 0 700 400 ft Figure 1 STUDY AREA CONTEXT 72 PEI 0!121 6UO-1 t m C 02 LXc d �r 3� C R Y O d 3 ori N C C7 U Qn E CO C1 H N 3 � C O O L � CL m d � m 111 U Oj Z H Z 0 m D W a N L the latter drainage area is more accurate. Drainage area boundaries for Silver View Pond are shown in Figure 1. Of the 145.7 acre drainage area, about 36.7 acres (25.2 percent) is presently impervious surface (e.g. rooftops, roadways and parking areas). These figures assume' completion of the remaining multifamily residential units at Silver Lake Woods North but do not include any future commercial development that may occur along County Road I or TH 10. A breakdown of existing land uses within the drainage area•is shown in Table 1. Table 1. Existing land uses within Silver View Pond Drainage Area, November 1989. aIncludes about 10.8 acres which is anticipated to be developed for commercial use in the future. bExcludes internal streets and access drives within developments. Based on early conceptual plans for future commercial development along County Road I and TH 10, it is anticipated that roughly 10.8 additional acres of commercial use will be added to the drainage area at some point. Roughly 4.7 acres of this area would be impervious surface, resulting in a future total impervious area of 41.4 acres or 28.4 percent of the total drainage area. At full development, the projected land use composition and impervious surface ratio within the drainage area appears to be very reasonable; particularly in light of the fact that Silver View Pond was actually designed for a larger drainage area. On purely a storm water storage basis, Silver View Pond appears perfectly adequate to provide the remaining storage needs within its drainage area. On the other hand, as will be described below in the Water Quality section, the pond is ecologically at a nutrient 73 I Percentage of Land Use Acreage Drainage Area Upland Open Spacea 57.3 39.3% Wetland/Pond 17.5 12.0% Single-family Residential 17.2 11.8% Multi -family Residential 33.6 23.1% Commercial 9.8 6.7% Streets/Highwaysb 10.3 7.1% 145.7 Acres 100.0% aIncludes about 10.8 acres which is anticipated to be developed for commercial use in the future. bExcludes internal streets and access drives within developments.

Roughly 4.7 acres of this area would be impervious surface, resulting in a future total impervious area of 41.4 acres or 28.4 percent of the total drainage area. At full development, the projected land use composition and impervious surface ratio within the drainage area appears to be very reasonable; particularly in light of the fact that Silver View Pond was actually designed for a larger drainage area. On purely a storm water storage basis, Silver View Pond appears perfectly adequate to provide the remaining storage needs within its drainage area. On the other hand, as will be described below in the Water Quality section, the pond is ecologically at a nutrient 73 I threshold beyond which future problems with blue-green algae are likely. Consequently, serious consideration should be given to providing on-site pre -ponding for any major developments proposed within the drainage area in the future. A suitable natural location for such ponding appears available in an existing wet meadow which lies between County Road I and the old County Road I corridor at the north end of the drainage area. IV. STORMWATER SYSTEM Silver View Pond receives stormwater both overland and via a number of storm sewer outlets that empty directly into the pond. The Silver Lake Woods single-family residential development in the southwest portion of the drainage area drains to the pond via 3 storm sewer outlets; 12- and 15 - inch reinforced concrete pipes (RCPs) emptying into the south arm of the pond and a 27 -inch RCP emptying into the west arm. This system also drains portions of Silver Lake Road and County Road H-2. The Silver Lake Woods Multi -family development in the north - central portion of the drainage area drains directly to the pond via 2 18 -inch RCPs. This system also receives drainage from Silver View Plaza, Super America and Burger Bing at the north end of the drainage area. The Scotland Green apartment complex in the southeast portion of the drainage area largely drains to the pond overland, though there are several small culverts that serve as surface drains from the northernmost parking areas. all other portions of the drainage area drain overland to the pond. Silver View Park partially drains directly to the pond and partially to a wetland area adjacent to Silver Lake Road. This wetland then drains via an intermittent drainageway to the west arm of the pond. V. BIOLOGICAL CHARACTERISTICS OF BASIN A. Aquatic Vegetation Aquatic macrophytes within Silver View Pond were mapped on July 24, 1989. The distribution and density of macrophytes varied with water depth and location. The predominant aquatic macrophytes were elodea (Elodea canadensis), water milfoil (MXriophXllum verticillatum), white water lilies (jymphaea odorata, and yellow water lilies (Nuphar variegatum). In scattered, very shallow locations along the fringes of the pond, lotuses (Nelumbo lutea) have become established. A few floating colonies of blue-green algae were observed. The pond margins were vegetated with typical emergent wetland plants including cattails (Typha latifolia), spike rush (Eleocharis palustris),and hardstem bulrush (Scirpuus acutus). 74 Elodea was found to be' the dominant macrophyte in shallow water (i.e. 3 feet or less). In areas of deeper water, water milfoil became dominant; however, when water depth reached about 5 feet, water milfoil growth became very sparse. Some sparse, scattered patches of sago pondweed (Potamageton pectinatus) were also found in deeper water. Overall, the composition of macrophytes within Silver View Pond is not particularly diverse as would be expected of a relatively shallow and recently created basin. Silver View Pond also supports a number of species of algae, the most visible of which is filamentous green algae of the genus Ulothrix. Limited amounts of blue -green algae were also observed. Since algal populations are important indicators of the pond's water quality, a detailed discussion of algae is contained in the water quality section of this report. B. Aquatic Wildlife Habitat Value The wildlife habitat quality of the pond and its contiguous wetlands is generally good. Because of its extensive macrophyte growth and the associated high invertebrate population, the pond supports a variety of waterfowl during the spring, summer and fall. The primary waterfowl species using the pond are mallards (Anas lat r nchos), wood ducks (Aix sponsa) and Canada geese (Branta canadensis). During the summer of 1988, we observed at least 3 mallard and 2 wood duck broods on the pond at one time. This unusually high density of waterfowl broods indicates that Silver View Pond provides the high protein invertebrate diet required by young waterfowl. However, it also suggests that hens with broods were more concentrated due to drought conditions in 1988. Since hens will often travel some distance from the nest site to reach suitable brood habitat, it appears that the pond may have been a "magnet" for hens nesting some distance away. While the pond provides an excellent food source for youn.- waterfowl, the dominant macrophytes are not generally considered high quality food for adult ducks. Waterfowl food value ratings have been assigned by the Minnesota Department of Natural Resources to the common aquatic plants of Minnesota. Elodea, water milfoil and yellow water lilies which dominate Silver View Pond are all rated as having slight to fair waterfowl food value (Key to the Common Aquatic Plants of Minnesota, Minnesota Department of Natural Resources Special Publication No. 53; Carlson and Moyle,reprinted 1973). White water lilies and lotuses have no waterfowl food value. Sago pondweed which grows sparingly in deeper water and spike rush which grows in scattered patches on the pond margin are both rated as 75 excellent waterfowl food plants. Little high-quality upland nesting habitat exists'in close proximity to the pond, the primary reason being mowing patterns on adjacent lands. Canada geese regularly rest and feed on Silver View Pond. As many as i0 geese were observed feeding on mowed grass and grass seed on uplands immediately adjacent to the pond. The combination of mowed grass and open water has made the pond highly attractive to geese. Nesting habitat for geese is very limited since typical nesting sites consist of muskrat houses or dry -hummocks within shallow marshes. The only suitable nest location appears to be the shallow marsh/shrub swamp which lies between the pond and Scotland Green Apartments on the east arm; this area appears large enough to support only one pair of nesting geese. Since geese usually return to areas they have previously used (bringing their broods with them), the number of geese using the pond is likely to increase with time. It is likely that geese will become a problem to adjacent landowners and the city due to the vegetation damage and feces geese leave behind. This is particularly likely if geese are allowed to nest in proximity to the pond. Silver View Pond is also utilized by a number of other bird species. Numerous green herons (Butori.des virescens) were observed feeding on minnows in the pond and a limited amount of suitable nesting habitat exists for this species in contiguous wetlands. Periodic feeding use by great blue herons (Arden herodias), black -crowned night herons lycticarax n,ycticorax) and common egrets (Casmerodius albus) would also be expected; however, the limited fish population in the pond is not sufficient to make it high quality feeding habitat for these larger heron species. Contiguous shallow marsh and shrub swamp areas are suitable habitat for sedge wrens (Cistothorus platensis), yellow warblers (Dendroicapetechia), and red -winged black birds (Agelaius hoeniceus) . P ._ Silver View Pond supports a limited population of muskrats (Ondatt,a z_ibethicus). The limiting factor for muskrats is the availabilit3• of den sites. All of the muskrats in the pond utilize bank dens rather than building houses from emergent vegetation (due to the limited amount of cattails and bulrushes in the pond). The number of potential den sites is controlled by soil types and by the territoriality of individual muskrats. Muskrats do some damage to shoreline areas with organic soils; however, they also consume macrophytes year-round and help to control macrophyte density. There is evidence of past beaver (Castor canad_ensis) activity around Silver View Pond; however, no beaver presently inhabit the pond. While beaver would add to the wildlife diversity of the pond, they are incompatible with 76 M Aspen/Oak Forest Shrub Swamp t#�:�� Old Fleld EDWet Meadow/Shallow Marsh Area Boundary 77 91 lcfl4 \J 0 200 400 ft Figure 3 1 l EXISTING WILDLIFE HABITAT water level control and the maintenance of landscape plantings within adjacent residential areas and Silver View Park. Should beaver become re-established in the pond, it is probably most prudent to have them removed. If they are allowed to recolonize, the outlet structure will need to be cleaned on a continual basis and any hardwood trees to be protected should be wrapped in 1/2 inch mesh hardware cloth to a height of 3 feet. C. Upland Wildlife Habitat Value Several areas of good quality upland wildlife habitat exist in close proximity to Silver View Pond (Figure 3). Along the both shores of the south arm are stands of 10 to 20 year-old aspen which provide good habitat for songbirds and also screen the pond from human activities in the adjacent multi- and single family residential areas. Other than the contiguous shallow marsh/shrub swamp on its south shore, the lands adjacent to the east arm are essentially devoid of habitat value. Because of the narrow strip of dedicated park land along this arm, there are only limited opportunities to improve upland habitat. Similarly, the west arm has little upland vegetation to buffer it from adjacent residences and Silver View Park. In contrast to the east arm, the west arm has considerably more dedicated land adjacent to it to allow upland habitat improvement. The City has already undertaken landscape work in Silver View Park which includes an extensive planting of fruit - bearing trees which will enhance the area for songbird use. There also is an excellent stand of aspen, oak and elm with a dense shrubby understory that extends northwest from the west end of the west arm of the pond. This area is excellent habitat for cottontail rabbits (Syl_vilagus floridanus), ring-necked pheasants (Phasianus colchicus), gray squirrels (Sciurus carolinensis) and various songbirds and small mammals. This area extends into the northwest corner of Silver View Park. As mentioned above, upland nesting cover for waterfowl is limited in the pond area by the present pattern of extensive mowing and by the limited amount of available public land around most portions of the pond. It would be a very cost- effective habitat improvement measure to reduce the extent and frequency of mowing in certain areas adjacent to the pond. This would also reduce the area's attractiveness for geese. Supplemental plantings of dense native grass cover would further enhance nesting cover. These measures are discussed further in the Recommendations section of this report. 78 VI. WATER QUALITY A.Methods Water quality samples were taken from three locations in Silver View Pond on June 24, July 22, August 13, and September 2, 1989. Sampling locations are shown -in Figure 4. Zooplankton were sampled with a standard Wisconsin net equipped with a 80 micron bucket, phytoplankton (algae) samples were preserved with Lugol's solution, and water samples were filtered through a 0.5 micron glass -fiber filter and frozen for chlorophyll analysis. Chlorophyll was extracted with a 80-15-5 mixture of acetone -methanol -water for 24 hours and quantified at 665 nanometers (the wavelength for green pigment) on a Model 24 Beckman spectrophotometer. Surface -water samples were submitted to Northern Lake Service, Inc. (Crandon, WI) for analysis of total phosphorus, total nitrogen, and, for the last two sampling dates, the sum of nitrate plus nitrite. It was not possible for the laboratory to analyze total nitrogen on the July 22 samples because the storage period for these samples was exceeded. Secchi disk data were not collected because transparency was generally to the sediment surface even in the deepest parts of the pond. B. Results Phosphorus Phosphorus is typically the limiting nutrient for aquatic plant growth in metro area lakes. The level of eutrophy in a lake or pond is typically a function of the water body's phosphorus concentration. A concentration of 20 to 30 ug/L (micrograms per liter or parts per billion) is considered the point where a mesotrophic water body becomes eutrophic. It is clear from the phosphorus data collected (Table 2) that Silver View Pond is eutrophic but that its three arms are not similar in water quality. For instance, the east sampling location always has the lowest phosphorus concentration, often by a factor of two. This location had an average phosphorus concentration of 65 ug/L (range 58- 73), in contrast to an average of 123 ug/L (range 120-125) for the west sampling location. The south sampling location was intermediate, with an average phosphorus concentration of 96 ug/L (range 70-120; the September 2 south sample was not included, as it appears this sample was contaminated, having a concentration of 935 ug/L). These phosphorus data suggest that most of the phosphorus load is introduced in the west and south arms of the pond, �. and that at least 25 to 50 percent of the phosphorus is being lost to the sediment by the time the water reaches the 79 PH gNe-1 6uo� 80 Z_ J a d w a� an iz co)ul O co tp O o C) Z C r F� w w Q co)ul C) co c o C) w Q V J U W Q toOv POCl) NN o a C Z F- tn to at to Ln to 0 0 0 0 0 0 000000 E v v v v v Z _N 0 000 000000 _ 000 P.- ^n t7 to Or O) T to r in to � r r 7 Z 000hOMM40Ntotn t0 N N en N 01 N N N N N 0 Jr r r r r IM im CL M u'1 to t0 �n 1� N v O t0 u7 r M 7 N N O O N 7 7 N NIm t0 I 7 J S U w3:0w3rnw3cnw3u� w u v< v N N N th N N N N N W to to t0 P N N m co co H Q � N c7 v O tp 1� O Of O r r 81 Q ❑ ❑ Z �a a� =w c� y wW ~ J_ cn N 4) .a cz eastern arm of the pond where the outlet is located. In essence, the pond is performing as it was designed; the majority of the incoming phosphorus is removed before being carried downstream to Rice Creek. The average total phosphorus concentration was lowest on June 24 (83-ug/L), but was relatively constant the -rest of the summer, varying between 95 and 101 ug/L) (Figure 5). Chlorophyll Chlorophyll is a convenient measure of the algal density (and hence primary productivity) in a lake. It is clear from the chlorophyll data that algal growth is controlled by the variation in phosphorus concentration described above. A scatter plot relating chlorophyll and total phosphorus shows a statistically significant relationship with a correlation coefficient (r) of 0.85 (P< 0.01; Figure 6). This relationship strongly suggests that phosphorus availability in Silver View Pond is limiting the growth of algae. As sediment -borne phosphorus settles out and is lost to the sediments, less algae can grow. As with phosphorus, chlorophyll concentrations declined as water moved through the pond toward the outlet at the east end. Chlorophyll concentration averaged 39 ug/L over the summer, and was fairly constant over time until the last sampling date when the three sites averaged 51 ug/L (Figure 7). Since phosphorus was did not appear to be higher on September 2 than on the earlier sampling dates, (although the anomalous phosphorus concentration of 935 ug/L occurred on that date), there may have been slightly more chlorophyll produced per unit phosphorus. Nitrogen In eutrophic systems such as Silver View Pond, nitrogen limitation of algal growth is common, because an excess of phosphorus allows algae to increase until the next most abundant nutrient becomes limiting; this nutrient is almost always nitrogen. In general, it is thought that systems with a total nitrogen -to -total phosphorus (TN/TP) ratio less than about 15=to-1 are limited by nitrogen. Silver View Pond has an average TN/TP ratio of 13.4 -to -1, indicating that the pond's algae are slightly nitr6gen- limited. This is important because blue-green algae are likely to dominate nitrogen -limited systems because many blue-green species can obtain nitrogen from the atmosphere whereas other types of algae cannot. Blue-green algae are nuisance algae because they tend to form relatively large, unsightly colonies that float at the water surface. Occasionally blue -greens cause other problems, such as odors as they decay or toxic blooms that can harm animals (both wild and domestic) that consume the water. 82 120 Ic 6/24 7/22 8/13 9/2 1989 • (l Figure 5 AVERAGE TOTAL PHOSPHORUS CONCENTRATIONS SILVER VIEW POND 83 60 50 40 J a� 30 20 10 0} 0 y = 8.0780 + 0.30583x R42 = 0.715 20 40 60 80 100 120 140 TP (ug/L) Figure 6 RELATIONSHIP BETWEEN CHLOROPHYLL AND TOTAL PHOSPHORUS CONCENTRATIONS SILVER VIEW POND 84 ■ 20 40 60 80 100 120 140 TP (ug/L) Figure 6 RELATIONSHIP BETWEEN CHLOROPHYLL AND TOTAL PHOSPHORUS CONCENTRATIONS SILVER VIEW POND 84 SC N 6/24 7/22 8/13 9/2 1989 Figure 7 AVERAGE CHLOROPHYLL CONCENTRATIONS SILVER VIEW POND 85 5C J 4C a O cr O 30 J 2 U W U 20 Q W Q 10 N 6/24 7/22 8/13 9/2 1989 Figure 7 AVERAGE CHLOROPHYLL CONCENTRATIONS SILVER VIEW POND 85 Apparently the algae in Silver View Pond are still obtaining enough nitrogen, because there is a statistically significant relationship between total nitrogen and and the quantity of algae, as measured by chlorophyll (r =0.88; P< 0.01)( Figure 8). Presumably, at higher algal densities algae are running short of nitrogen at which time blue - greens begin to obtain nitrogen directly from the air through the process of nitrogen fixation. On two sampling dates, dissolved nitrogen compounds (nitrate plus nitrite) were measured, and five of the six samples were below the detection limit of 50 ug/L ( see Table 2), indicating that the algae were taking up most of the available nitrogen. Algae Given that the system seems to be slightly nitrogen -limited, one would expect blue-green algae to dominate the phytoplankton of Silver View Pond. However, on every sampling date, the algae population of the pond was dominated by a non -blue-green species, Ce_ratium (Table 3). The balance of the arae on each date were either blue - greens or green algae. However, except for :Anabaena, the blue -greens observed in were of a type that can not obtain nitrogen from the air. These results apply to water samples obtained from the middle of each arm of Silver View Pond. Table 3. Estimated composition (by biomass) of phytoplankton in Silver View Pond, 1989.

In contrast, colonies of blue-green algae were observed floating around the margins of the pond on both June 24 and September 2. On June 24 large colonies of Oscillatoria or L.yri bLa (both non nitrogen -fixing blue -greens) and filamentous green algae were observed floating at the surface. On September 2 numerous (at least 50) colonies of the blue-green alga Nostoc had been blown to the shore of the western arm. Nost_oc colonies are hard, hollow green spheres slightly smaller than a ping-pong ball. When examined under a microscope, the colonies were rich with heterocysts, which are the special cells that fix nitrogen. 86 y = - 10.304 + 4.0862e -2x R^2 = 0.765 70- 60 50 a� 40 U 30 20 ■ 10 0 0 y = - 10.304 + 4.0862e -2x R^2 = 0.765 ZUU 4UU 6UU UUU 1 UUU 12UU 1 400 1600 1800 TN (ug/L) Figure 8 RELATIONSHIP BETWEEN CHLOROPHYLL AND TOTAL, NITROGEN SILVER VIEW POND 87 E��a ti ■ ZUU 4UU 6UU UUU 1 UUU 12UU 1 400 1600 1800 TN (ug/L) Figure 8 RELATIONSHIP BETWEEN CHLOROPHYLL AND TOTAL, NITROGEN SILVER VIEW POND 87 E��a Zooplankton Although no quantitative examination was made of the zooplankton, it was clear from empirical review of the samples taken that the community is dominated by small - bodied copepods, rotifers, and cladocera. No large -bodied Daphnia were observed. This qualitative observation suggests that the numerous minnows and other small fish observed in the pond are visually preying on larger forms of zooplankton whereas smaller forms are escaping detection. If a complete winterkill of fish occurred, large Daahnia_ would become common and in turn would graze algae -more efficiently. This would result in a lower amount of chlorophyll per unit phosphorus, and could result in a bloom of large colonies of the nitrogen -fixing blue-green alga Aphanizomenon. C. Discussion Silver View Pond is rich in phosphorus, averaging between 65 and 123 ug/L in the different basins. The west and south basins appear to be receiving the majority of the phosphorus loading from storm -sewer runoff; however, the phosphorus concentration -is reduced substantially by the time the water makes its way to the east basin. Algae grow in proportion to the concentration of phosphorus, so algae populations are lowest in the east basin. High densities of algae reduce light significantly, so that macrophyte growth is inhibited. In addition, macrophytes have more access to light in shallow water. The eastern basin is shallow and has the least algal growth; consequently, macrophyte growth is highest in this part of the pond. The nitrogen -to -phosphorus ratio (TN/TP) indicates that Silver View Pond is slightly limited by nitrogen, so that blue-green algae are sometimes found floating on the surface. It is somewhat surprising (but desirable) that blue -greens are not more abundant in this system. It is likely that the TN/TP ratio need only be lowered slightly more to shift the algae completely to the less -desirable blue-green algae. This shift could occur if slightly more phosphorus is introduced to the system. Therefore, future watershed management should minimize additional loading of phosphorus. However, if phosphorus is greatly reduced, water transparency could increase sufficiently to greatly increase macrophyte growth. It appears that some algal growth is desirable to shade macrophytes; thus, it probably is most desirable to limit future phosphorus loading through altering land -use practices, and to not pursue large reductions in`phosphorus loading. Reasonable measures might include additional upstream ponding for any neva developments 88 that are proposed within the drainage area, restrictions on the use of phosphorus -containing fertilizers, and limited harvesting of aquatic macrophytes. Large reductions in phosphorus could only be achieved by constructing basins upstream from Silver View Pond to treat storm water already flowing into the pond or by applying chemicals which cause phosphorus to precipitate and settle out. The application of herbicides would create too drastic a change in the ecology of the pond and would most likely lead to further problems with excessive macrophyte growth. Although it may be desirable to remove some macrophytes, herbicides leave organic matter and nutrients such as phosphorus in the pond; macrophyte harvesting does not leave behind these residues. VII. RECOMMENDED MANAGEMENT MEASURES A. Water Quality Measures 1. Ponding Pre -ponding of storm -water runoff from new commercial developments should be undertaken where practical to minimize additional phosphorus loading to Silver View Pond. Potential locations for such ponding are wet meadow wetlands between County Road I and the old County Road I corridor at the north end of the drainage area and similar wetlands east and west of Silver Lake Road on the west edge of the drainage area. Additional ponding for storm water already flowing via storm sewers to the pond is not recommended. 2. Limitation of Phosphorus Containing Fertilizers It is recommended that the City consider an ordinance to eliminate the use of phosphorus -containing lawn fertilizers within the drainage area of the pond. Nitrogen and potassium -containing fertilizers are sufficient for lawn maintenance and will minimize both aquatic macrophyte and blue-green algae problems. 3. Limited Harvest of ASLUatic Macrophytes It is recommended that the City undertake limited harvesting of aquatic macrophytes within portions of Silver View Pond. The portions where macrophytes are presently a problem and where harvesting would not promote blue-green algae problems are shown in Figure 9 and summarized as follows: - southern portion of the south arm (approximately 1 acre) - shallow eastern portion of the east arm (approximately 1.5 acre) 89 Potential Future Pond mlAquatic Plant Harvest Neat Cover Planting Area Boundary /D0 it Figure 9 MANAGEMENT RECOMMENDATIONS We have investigated the practicality of contracting for commercial aquatic weed harvesting service for these portions of Silver View Pond. Commercial harvesters we contacted generally indicated that the acreage to be treated within Silver Lake Pond was too small for normal mechanized harvesting to be undertaken. Per hour costs for harvesting service are normally $90 to $100/hour on harvesting projects requiring a week or more. Since harvesting of Silver View Pond with normal, mechanized means would take less than one day, it would not be economically feasible to bring in weed harvesting machinery for so short a period. Also, weed harvesting machines require excellent access facilities (preferably a concrete ramp) to gain entry to the waters to be harvested. Since Silver View Pond does not have such facilities, it appears that lack of access precludes the use of such heavy machinery. An alternative to normal weed harvesting techniques which appears more suitable for small scale projects is a simple winch and cable system used to encircle the area to be harvested. This method could be carried out by City maintenance personnel or by a private contractor. It is important that any personnel handling aquatic plants wear rubber gloves due to the high likelihood of contracting swimmer's itch. Harvesting should be undertaken up to twice the first season; once in June and again if and when the macrophytes have shown substantial regrowth. Since the sandy pond substrate is not highly conducive to macrophyte re- establishment, future harvests probably can be undertaken with decreasing frequency. Harvested macrophytes can be composted and used as a soil additive in agricultural, garden and horticultural applications. This method has been successfully been utilized in Massachusetts as an alternative to landfill disposal of harvested macrophytes. S. Wildlife Habitat Measures 1. Reduced Mowin There are a number of upland areas adjacent to the pond which could provide improved upland nesting habitatifor waterfowl if mowing were substantially reduced. Potential areas for mowing reduction are shown in Figure 9. Such areas should be mowed once every 4 to 5 years to hold back encroachment by woody vegetation. In addition to improving nesting habitat, reduced mowing would also reduce the pond's attractiveness for Canada Geese, thus helping to forestall problems commonly Fssociated with large goose numbers. Also, any artificial feeding that might be occurring on 91 private lands around the pond should be discouraged so as not to delay geese during migration. 2. Upland Nest Cover Plantings Upland nesting cover would be further enhanced if some areas of dense, native grass cover were established in close proximity to,the pond. One potentially suitable area would be the the large hills at the south end of Silver View Park (see Figure 9). Dense nesting cover would also act to minimize erosion on these steep slopes. Seeding of such material is not proposed in the immediate area of the park's amphitheater, since it would be incompatible with heavy human use. Also, if such seeding were done around the in place landscape plantings, mulching around the bases of trees will be necessary to prevent grasses from competing with the trees for moisture. Again, any areas seeded in this manner should be mowed every 4 to 5 years to minimize woody competition. Prescribed burning is normally the preferred method for periodically rejuvenating such stands; however, this method may not be compatible in the area of the pond. 3. Additional Nest Structures There is presently one wood duck nesting structure on Silver View Pond near the junction of the three arms. At least two additional structures could be reasonably added, preferably one near the south end of the south arm and another at the east end of the east arm. If possible the existing structure should be relocated to the west end of the west arm. In this manner, the nesting structures will be placed to be as far apart as possible, providing the hen wood ducks with ample space to nest and raise broods without interacting with each other. Wood duck nest structures should be placed in sheltered areas to blend in with existing trees. Other types of nesting structures, such as purple martin and/or bluebird houses, might also be considered to maximize the interpretive value of the pond area. 4. Monitor Canada Goose Use and Prevent Nestin Canada goose use in the pond area is already high and is likely to increase in the future. In order to reduce the likelihood of future goose problems, goose use should be monitored to determine if deterrence or control measures should be undertaken. Of particular importance is the need to prevent goose nesting on the pond, since any goslings produced will return to the same location to nest themselves, thus aggravating any problems that may arise. Should geese begin nesting, the Minnesota DNR Area Wildlife Manager should be consulted on deterrence methods. 92 5. Monitor Beaver Use and Prevent Colonization The pond should be monitored for beaver use periodically and any beaver that move in should be removed. Should beaver colonize the pond, the outlet structure will need to be cleaned continually. Also, any landscape plantings that are to be protected from cutting must be wrapped with 1/2 inch mesh hardware cloth to a height of 3 feet. 93 MEMO TO: MAYOR AND COUNCILMEMBERS FROM: MARY SAARION, DIRECTOR PARKS, RECREATION AND FORESTRY DATE: SEPTEMBER 12, 1990 1 SUBJECT: ESTIMATE OF COST TO LIGHT CITY HALL WEST SOFTBALL FIELD As requested by Councilmember Quick, I have received an estimate for lighting City Hall west softball field. A number of years ago Musco Lighting, Inc. provided the City with an estimate of about $50,000 for lighting both City Hall fields, The cost estimate today for lighting the single field is 39 000. Musco is a reputable sports lighting company in the State of Minnesota. Many metro facilities have installed Musco lighting. The lighting is specific and offers excellent playing light. The fixtures and poles are of the highest quality. Musco Lighting recently installed lighting at the New Brighton Freedom Park softball field located on Silver Lake road and the Mounds view High School football field. Staff believes that lighting the west field, allowing for four games per night, would benefit the City for these reasons: 1. One softball field generates parking needs of approximately 54 cars during peak game turnover times from 6:30 - 7:30 p.m. This is the same time that parking is needed for Council meetings. Having four games on one field would spread out the parking needs throughout the evening. 2. The vacated field space could provide new opportunities for facilities such as additional parking, tennis courts, green space or other. 3. Playing four games per night on one field versus playing four games per night on two fields would save maintenance time and costs of field preparation. Also, future expenses such as turf control and sprinkling would be less for one field versus two fields servicing the same number of teams. One final note is that the east softball field will most likely be dug up when well number 1 is moved. If you wish me to provide the Council with additional information regarding softball field lighting, please call me at ext. #20. MS/SL Craig Gallop Sports Technology, Inc. P.O.

Dear Diary, The following information is provided to light the softball field at City iiall Park. We propose to light the facility to 30 footcandles infield and 20 footcandles outfield using the Diusco Sportscluster-2 lighting system. This will provide you with excellent lighting that will be maintenance -free throughout the years. The poles would be galvanized steel which would also be maintenance -free. ,1:.. The Sportscluster-2 lighting system uses new technology in control of light both on and off of the field. By redirecting potential spill light back onto the playing field, the system effectively reduces spill and glare light while increasing field light by 25% per fixture. The Sportscluster-2 will reduce the glare light on Highway 10 and will reduce the glare light from the eyes of the ball players. Installation shall include the following: ............. $39,000.0o. 1. Provide galvanized steel poles. 2. Provide Musco Sportscluster-2 lighting system. 3. Provide underground electrical system. 4. Mount lighting to poles and set poles. 5. Install complete lighting system and electrical system. 6. 5 year warranty on lighting system. 7. 15 year warranty on poles. Please feel free to call if you have any questions.

MEMO TO: PARKS AND RECREATION COMMISSION FROM: MARY SAARION, DIRECTOR PARKS, RECREATION AND FORESTRY DATE: SEPTEMBER 20, 1990 SUBJECT: PARK MAINTENANCE The City Council approved the recommendation that the Public Works Department should be responsible for park maintenance because they have the control over maintenance activity. The park maintenance operations will also be the responsibility of Public Works. The Parks, Recreation and Forestry Department continues to administer planning and budget responsibilities for park development and planning, and parks capital as advised by the Parks and Recreation Commission. In conclusion, all park maintenance concerns will be referred to Public Works and all park development and planning concerns will be referred to the Parks, Recreation and Forestry Department. MS/SL MEMO TO: DON BRAGER FROM: MARY SAARION DATE: 09-04-90 SUBJECT: CAPITAL OUTLAY ITEMS Listed below are capital outlay items requested for the Parks, Recreation and Forestry Department and the reasons or need regarding the requests. 1. Replacement for the Puppet Wagon ($10,000)- this past year the puppet wagon ran on its last legs. The body is so deteriated that the exhaust fumes penetrate the cab from the sides and bottom of the body. The exterior looks bad because of the rust. The engine is in poor working order especially due to a bad transmission. The roof leaked profusely this summer and when brought in for repair the service man suggested that we not put any money into the repair because the vehicle was not worth the cost of repair. The vehicle is used as a puppet wagon during the summer months and a rink flooding vehicle during the winter months. On occasion it is also used as a support vehicle during winter time sewer or water main breaks. The requested funding includes a used full van vehicle and includes funding for body work. 2. Sound Equipment for Puppet Wagon ($460) - Currently the puppet wagon staff has used their own equipment or equipment which they have been able to scrounge up for use of sound equipment during the summer season. The sound equipment has not been the best and limits the puppeteers because of need to share microphones. Staff wishes to purchase sound equipment which is adequate for the performances and can be adapted for use in the puppet wagon. Equipment would include wireless microphones, amplifiers, 400 watt inverter for power, cassette recorder and switch. 3. 2 Roaster ($300) - The two City Hall roasters no longer working, are old and need replacement. These roasters have been available to city groups such as the PTA's, Scouts, and groups using the City Hall or picnic areas, and used for various city functions. 4. Cable ropes for swings ($5,500)- chains used on the swings at various park playgrounds frequently chip the paint on the metal posts due to misuse by children. One of the misuses is the wrapping of swing chains around the top post. Also the chain links often times wear out and must be replaced. A new product on the market is cable ropes. These ropes do not damage the post paint if wrapped around. There are no links so the danger of weak links does not exist, requiring no replacements. The cable ropes do not get as cold as the metal chain so can be easily used in the wintertime for swinging. The cable ropes are attractive. Currently the City Hall and Lakeside Park swings are the only city facilities using the cable ropes. Staff would like to replace all the chain links with cable ropes on the swings at Groveland, Woodcrest, and Hillview Parks. 5. Park Signage ($500.00) - It has been requested by the Parks and Recreation Commission and city residents that more signs be placed in the parks publicizing the rules and regulations pertaining to park usage, curfew, ordinances, emergency numbers, etc. 6. Woodcrest Hockey Boards ($25,000) - The Woodcrest Park hockey rink is the designated rink used by Lake Region Hockey. It has extensive use by Irondale High School broomball leagues and is a favorite site for league play. The hockey boards however are in terrible shape and need replacement for safety and aesthetics. The replacement of the boards would include materials and construction of the new rink in the latest style and construction of hockey rinks including top of the line materials, turn key, labor, painting, posts, gates, fencing, etc. It is estimated that such a facility would have a 20-25 year longevity. The current hockey boards are very old, at least 15-20 years old. The new design of hockey boards use lateral boards at the ends providing durablity. 7. Lambert Park Parking Lot and Burying of Storm Water Pipe ($ Lambert Park currently does not have a paved parking lot. Parking is on a dirt portion of the park which is unsightly and lacks definition. Staff wishes to provide an asphalt parking lot with curbing. This would improve the aesthetics of the park and could provide for some hard surface play areas such as basketball and foursquare during summer playground activities. Currently a large open storm water drain pipe is located in Lambert Park. Not only does it take away space but it is also unsightly and could be a safety hazard for children who climb on the pipe or enter the pipe. This pipe could be buried and connec ted to the storm water drainage plan. 8. Silver View Park Improvements $10400) - These improvements are listed in the Silver View Park Improvement Plan and include picnic tables, benches, grills, 2 glider swings, and completion of the sprinking system including the soccer field and the area around the picnic shelter. 9. City Hall Softball Field Sprinkling ($14,000) - City Hall Fields would finish the sprinkling needs of the community parks in the City. To date the fields at Silver View and Greenfield Community Parks are sprinkled.City Hall fields are covered with weeds and stickers because grass is vertually impossible to grow without the use of sprinkling. City Hall gounds are currently sprinkled in the front of City Hall and the lush grass is beautiful. Such success is desired in the athletic fields. 10. New Pick-up Truck for Forestry ($17,000) - Currently the Forestry Assistant is using the old LUV truck which i. on its last legs. The body is rusting out and the floor is full of holes and the engine is tired. A new truck for thecrester would enable the City to provide the current forestry truck for use by the Forestry Assistant. With this plan each wculd have a truck bed capable of caring the necessary size of materials such as branches, trees and shrubs, mulching material, etc. The trucks would be more respectable when in the public eye. 11. Additional Sprinkling at Greenfield Park ($1,200; - This additional sprinkling would cover the area around tha playground area and building to provide water for the landscaped bushes and trees. 12. Installation Costs ($2,500) - for park equipment including grills „ picnic tables, benches, glider swings and playground equipment (if donated by a charitable organization) fcr Silver View Park. 13. Weed Harvesting ($2,000) - Initiation of a program to harvest weeds from Silver View Park pond is a top priority indicated by residents living around Silver View Park. 14. Pathway Completion ($7,000) - This has been inc_cated as a priority by a majority of City Survey participants anM is a top priority by the Parks and Recreation Commission and S_lver View Park Task Force. Completion of the woodchip path arc=nd Silver View Park pond, finishing the two sections. 15. Lighting for City Hall Softball Field #2 ($39,OC:) - This is suggested if the softball field #1 must me abandoned for any reason or if the city feels that it would be more advantageous to maintain one field versus two fields while still serv_ng the same number of adult softball teams by the scheduling of fzur games per night on one lighted field versus two games per night on two unlighted fields.
