Next Meeting: TUESDAY, SEPTEMBER 17, 2002, 10:30 A.M. ARDEN HILLS CITY HALL UPSTAIRS CONFERENCE ROOM, 1245 WEST HIGHWAY 96 Comments on, "Draft Technical Memorandum for Shallow Soils site Alternatives Evalnation". Submitted by Paul R. Bloom On behalf of the TCAAP RAB 8-12-02 . We ofthe RAB acknowledge that with the current high wateT table it would be difficult and likely expensive to meet the requiTements of the ROD. The Temedial desigu associated with the existing wOTk plan will not meet the TequiTements of the ROD for complete removal to cleanup goals agreed to in the ROD. Therefore, a modification of the ROD is needed. We also acknowledge that except for areas affected by the phytoTemediation disaster and small areas of hydrocaTbon contamination the contaminants of concern are immobile and do not represent a risk to ground water at the present time. Weare concerned, however, that a hasty decision may have potential serious consequences fOT the future use of property. We acknowledge that funding is available for the current fiscal year and that delay could be costly. HoweveT, no cost estimates weTe pTovided as is TequiTed for decisions on Temedial alternatives for a ROD. Concurrence for a modification in work plan before completing the slow process of ROD modification could be risky. It should be borne in mind that future discussions may result in changes that will require Teturmng for additional work. The property in question is in the area designated fOT transfer to the local community. In addition to protection of health and safety the future use of the property by non-Army users must be considered. . When a public hearing is held for the ROD modification both health and safety and utilization of the property will be important topics of discussion. The public hearing may not be without controversy. We conclude that none of the alternatives in the Memorandum are acceptable. Alternative 1. (Continue on the current wOTk plan that limits digging when the wateT table is encounteTed, even if cleanup is not completed, and cover with a minimum of 2 feet of fill), This does not assure that theTe will be a deep enough cover oveT all ofthe remaining polluted soil and theTe is not enough characterization data to provide information fOT good institutional controls. At the meeting on August 7, 2002 the MPCA suggested that with a cover of only 2 ft. the institutional controls would include Tequirements for a fence and long-term monitoring, Alternative 2 (DewateT and Temove all the COC to the Temediation goals). The Army has stated that this is expensive, but provided no cost estimates. Alternative 3. (Wait until the dry season), This pTobably will not wOTk given the current exceedingly high water table. Alternative 4 (Bring in 2 feet of cover for the Temaining problem grids, then do subsurface sampling of the extent of the Temaining pToblem). As with Alternative 1 this would require institutional controls that would include treating the site as a landfill and requiTe both a fence and long-term monitoring, At the August 7, 2002, meeting the Army stated that they would be willing to consider a 3 ft. cover. The . MPCA stated that with a 4 ft cover no fence is necessary. A 4 ft coveT will be much more pTotective and limited uses of the land would be possible if characterization is competed, monitoring is instituted, and institutional controls are put in place. Depending on the contouT of the land, piling 4 ft of soil on the surface could create a mound, which would make it mOTe likely that contaminated soil will be . accidentally exposed and the irregular land surface might furtheT limit use of the property. The Army suggests alternative 4 is less expensive but gave no cost estimates. Future costs that result from instituting land use controls need to be considered, This could include, but are not limited to, upkeep of fencing, monitoring wells, etc. The possibility of unforeseen damage to health and safety must be considered. The preferred option is one that would convert the property into its best possible condition fOT use and pTovide maximum protection for health and safety. We suggest a modified option that combines Alternatives 1 and 4, but with a thicker cover. The contaminated soils should be Temoved to the wateT table, coveTed with a minimum of 4 ft of clean fill, the Temaining contamination characterized, long term monitoring instituted, and institutional controls be put in place. Any solvent contamination encounteTed must be removed to the water table and the boundaries of the contamination must be established. GTound water data on hydrocarbons must be obtained. . . 1HE MCKNIGHT FOUNDATION Rr.'If',,:p"VC-D 1::",,_1 1:" 600 TeF Tower 121 South Eighth Street Minneapolis1 Minnesota 55402 612-333-4220 612-332-3833 fax info@mcknight.org . SEP - 5 2002 September 3, 2002 I CITY OF N~U'i~ HILLS DeaT Friend: In the next few weeks, The McKnight Foundation will announce a public service campaign that will be unique for us and important to our community, On SeptembeT 28, we will join with 10 campaign partners to launch "Embrace Open Space," You will soon Teceive an invitation to a special event to kiek off this campaign, In the meantime, though, I want you to be among the first to know about this initiative, its significance, and why we aTe doing it. McKnight is making a yearlong commitment to Embrace Opcn Space. We have planned and will implement its activities in cooperation with local grassroots advocacy groups, government agencies, and an academic center, Combining advertising, a website, publicity, special events, and citizen action, the campaign focuses on the need to protect open spaces in the Twin Cities metro aTea. . We hope that through this campaign, individual citizens not only will Tecognize the importance of protecting open spaces, but will also make a peTsonal conunitment to the issue. Citizens need to know that critical decisions are being made daily in the metro region about which land we build on and which we protect, We have alTeady lost many special places because too few citizens have taken an active role in these choices. And although we know that Minnesotans value open spaces, theiT sincere concern and appreciation hasn't always translated into public action, The purpose of the Embrace Open Space campaign is to connect individuals with public decision-making. Citizen involvement does make a diffeTence. OuT emphasis isn't on any single open space (although we will celebrate "Ten TTeasured Sites" that aTe in jeopaTdy) OT the decision of any particular body. Instead, our purpose is to engage Twin Citians in broad advocacy of protecting and Testoring open spaces. We want to encourage everyone to give public voice to this issue. I am very enthusiastic that this level of media exposure, combined with public engagement activities by OUT partneT organizations, will dramatically change the discussion about open spaces in this Tegion fOT years to come. I welcome your questions OT comments on Embrace Open Space and McKnight's role. You can find out more and give us YOUT feedback by visiting the campaign website at www.EmbraceOpenSpace.org. . \\'\\'w.mcknighr.org . . . . . . . . . . . . . September 3, 2002 Page 2 I hope that as you learn more about Embrace Open Space, you too are inspired to consider the importance of this issue. Sincerely, Rip Rapson President, The McKnight Foundation P.S. By visiting our wehsite (www.EmbraceOpenSpace.org) you can explore our regional treasure map that highlights 10 open spaces as representative of the kind we need to protect.

QjJicitl(Ul!'gf? release of arsenal The Twin Cities Army Ammunition Plant (TCAAP) was built in 1941 on four square miles offarmland to support the nation's defense, No longer needed by the U.S, Army, control of the land is now being transferred to a variety of interests, In 1994 Congressman Bruee Vento established a Reutilization Committee to make recommendations for the future use of the site, The Friends of the Parks and Trails strongly support the Vento committee's recommendations for the TCAAP site, It appears that the 113 aeres eomprising the Rice Creek Corridor will be transferred to Ramsey County in the near future for the purpose of a reereational trail. We also understand that the 276 acres requested by the National Guard will be transferred to them, The Friends are strongly supportive of these transfers, What is in question is the 49 acre wildlife corridor connecting the area licensed to the National Guard to the east and the Rice Creek eorridor to the west. This eonneetion was one of the reeommendations in the Vento Plan, According to Joan Galli, Nongame Wildlife Specialist with the Minnesota DNR, "Recently, Arden Hills city officials have been lobbying the federal government to release all of the remaining acreage for redevelopment, The city's redevelopment plans stray from the Vento plan by including the 276 acres requested by the Guard and the 49-acre connecting parcel. Preservation of these two parcels in a natural state is critical to the site's role as an ecological hub connecting several regionally significant natural areas, and it would still leave about 600 acres available for redevelopment, Protection of these key parcels amounts to a rare, now-or-never opportunity http://www.friendsoftheparks.org/TCAAPmain.html 9/612002 The 1'win Cities Army Ammunition Plant land Naturalists seek to preserve valuable corridor Page 2 of2 to preserve a I5-mile habitat corridor stretchingfrom the 23,OOO-acre Carlos Avery WMA to the Mississippi River, Years from now, our children and grandchildren won't remember us for the housing developments or shopping malls our generation gave rise to; they will, however, appreciate our efforts to preserve their natural heritage, " The most effective way to assure those aeres are ineorporated into pub lie open spaee as a eonneetion between the Creek corridor and the National Guard lands is for Ramsey County to include the acres within the Rice Creek Trail Corridor.

URS . Septembcr 4, 2002 Honorable Mayor and City Council City of Arden Hills 1245 West Highway 96 Arden Hills, MN 55112 RE: Karth Lake Pumping Station Dear Mayor and Council: As directed by City Staff, we have completed a feasibility analysis for maintaining the level of Karth Lake under high water conditions, As part of this analysis previous studies and options have been reviewcd, in addition the current lake level have been surveyed, Both short term (temporary pumping systems) and long term (permanent lift station) solutions have been studicc\, ~arth Lake is approximately a 16-acre lake located in the northeast corner of Arden Hills sourh of CSAH ~6 and inbetween Lexington Avenue and Hamline Avenue, There are approximately 45 residential properties surrounding Karth Lake and Cummings Park is located on the southern end of the lqke Background Karth Lake is a land-locked water body under DNR jurisdiction and located within the Rice Creek Watershed District. The published normal water level is 929,8 feet above sea level. Residents have brought up the issue of high water levels in the lake numerous times since 1984, A table of water levels based on DNR published information, plat maps and previous studies into this issue are as follows: Table 1 - Lake Elevations (Feet Above Sea level) ._-~"- --,._--- Year Season/Month Lake Level (Feet) 1974 N/A 9298 1977 July 929,7 1984 June 936 1986 June 936 -, 1996 Spring 936,5 ._-~~~ 2002 SePtember 938,3 --,~---~ -- The City has set-up temporary pumping systcms two times in the past to lower the level of Karth Lake, .( Thc lake was pumped down in both 1984 and 1986 to a surface elevation of 934 feet.

In 1994 MSA looked into the feasibility of diverting the runoff into Karth Lake from Amble Drive to Pleasant Drive in conjunction with reconstruction work on Amble Drive, It was determined that runoff from Amble Dlive was only 8% of the total runoff into Karth Lake and it would cost approximately $70,000 to divert the runoff, It was determined that this solution would not be cost effective, In 1996 MSA looked into three different altematives for a permanent pumping system to draw down the lake level during high water conditions, The three pumping station altematives consisted of: Altemative 1- Forcemain to Wyncrest Court (Valentine Lake Storm System) Altemati ve 2 - Forcemain to Femwood A venue (Valentine Lake Storm System) Altemative 3 -Forcemain to Sunfish Lake Each altemative was evaluated with the option of using a trash pump, submersible pump or submersible pump with automatic controls, The following table outlines Options and Costs from MSA's analysis Table 2 - Options From 1996 Feasibility Analysis by MSA W nerest Court $21,200 $31,100 $34,100 Destination Fernwood $35,400 $45,300 $48,300 I Sunfish Lake $41,200______~__~ $51,100 $54,100 From MSA's feasibility repOlt Altemative I with a trash pump was the recommended option Current Conditions A surface water elevation of 938,3 feet was measured on September 3, 2002, from a visual survey it appears that all permanent structures i,e.... houses and garages are about 10 to 15 feet above the CltlTent lake elevation and do not appear to be at any risk of flooding, Although no permanent structures appear to be endangered there are numerous items such as private docks and landscaping submerged as well as numerous mature trees that have water one to three feet up their trunks, ~ Memorandum September 4, 2002 Page 3 . Options Temporary Option The temporary solution of drawing the lake level down is to install portable trash pumps and temporary above ground piping, The best route for the temporary piping is to run it through Cummings Park and outlet into a catch basin in the W ynerest Court cul,de,sac, The City of Arden Hills does not own equipment or piping large enough to pump the Kalth Lake down in a reasonable amount of time therefore equipment and piping would have to be rented for 3 to 4 weeks and monitored closely by operations and maintenance staff. It is estimated the cost for renting temporary pumping equipment and piping for 3 to 4 weeks will be approximately $8000 to $9000, Permanent Option As recommended in MSA's 1996 analysis a forcemain system conneeting from the south end of Kartb, Lake to thc storm scwer system in Wyncrest Court through Cummings park would be the prefened alternative bccause it is the lcast expensive alternative and could be completely constructed within City Property, ( MSA's report reeommended a pumping system which could draw down Karth Lake 2' in a 96 hour period, We believe that the draw down time could be extendcd without any delIimental effects and would allow for a smaller diameter forcemain and smaller pumps which would in turn lower the costs of a potential pumping system, It is recommended that a submersible pump be used similar to the pumps in sanitary lift station #3 for the compatibility of equipment, parts and maintenance, It should be noted that MSA's cost estimate did not have any budget for site restoration such as turf replacement or pavement repairs, which could be extensive in thc open trench pipe installation they proposed, The cuncnt estimated cost is outlined as follows: Table 3 - Preferred Option Revised Cost Estimate 4" HDPE Forcemain Directionally Bored (700 LF) Connect to Existing Manhole Pump Manhole Clearing and Grubbing Site Restoration Pump Control Panel 10 HP Submersible Pump Total $15,500 $1,000 $5,000 $2,000 $6,000 $5,000 $8,000 $42,500 4 Memorandum September 4, 2002 Page 4 . Funding Possible funding for any improvements could be funded by assessments to the property owners adjacent to Karth Lake, the Storm Water Utility Fund or by a combination of both, Coordination As mentioned previously Karth Lake is a DNRjurisdictionallake and located within the Rice Creek Watershed District. Any temporary or permanent pumping system solution will require coordination and permits from both the DNR and thc Ricc Creek Watershed District before any tcmporary or permancnt system is implemented, Recommendation If the Council elects to pursue either the temporary and/or peIIDanent options to pumping Karth Lake it is recommcndcd that the water be routed to the Wyncrest COUlt stOlID sewer system via Cummings Park, It is recommended that a permanent pumping station include a submersible pump compatible with the ( pumps used in sanitary lift station #3, It is also recommended that any pumping option would not draw down thc lake leveJlower than a surface elevation of 934,0, Sincerely, #~ Enclosures , 18 .-> H MLlNE A VENUE 1 ~ Cl ~ ~ '" , , (f)/ ::0 ::0 Cl )> n ~ rn "', ::0 r n rrl Z 0 ......
