CR 91-154 EAW - Ramsgate TownhomesJuly 30, 1991 I Y O ) G T 9 5 0 P K i Council Report 9i -154 EAW - RAMSGATE TOWNHOMES Proposed Action. Staff recommends the following motion: Move to adopt Resolution 91 -91 determining that there are no significant environmental impacts and Environmental Impact Statement is not required to be completed for the Ramsgate Townhomes overview Mark Jones has applied for a conditional use permit to construct 12 townhomes on the southwest corner of Hiawatha Avenue and Cambridge Street. On March 26, 1991 the Zoning and Planning Commission recommended approval of the Ramsgate Townhomes. On March 28, 1991 the City received a petition to complete an Environmental Assessment Worksheet (EAW) for the Ramsgate Townhomes. At the April 2, 1991 City Council meeting the Council ordered a discretionary EAW on the proposed Ramsgate Townhomes. The City Council had the option to order a discretionary EAW because the proposed townhomes are within 300 feet of Minnehaha Creek. If the townhomes had not been within 300 feet of the creek, the project would have been exempt from an EAW. The 30 -day written comment period for the EAW began on May 27, 1991 and expired on June 26, 1991. The purpose of the 30 day comment period is to' allow persons or governmental agencies to address the accuracy and completeness of the material contained in the EAW, potential impacts that may warrant further investigation before the project is commenced, and the need for an EIS on the proposed project. On July 16 the City Council tabled the matter to allow for additional study to be given to noise levels in the project area. A representative at the Environmental Quality Board (E.Q.B.) did state that this is the first time an EAW has been done for this small size of development. B As a result an E.I.S. has never been done for,this size of project. Primary Issues to Consider • What is'an E.A.W. and an E.I.S.? • What is the background for this E.A.W.? • What is the project and site description? • What agencies /individuals submitted.written comments? • What were the comments during the 30 comment period? • What is the staff conclusion as relates to the comments received? • What were the noise levels at various locations around the site? Supporting Documents. o EAW T esolution 91 -91 Nancy S. Anderso Plan r • o What is an E.A.W. and an E.I.S.? An EAW is def fined by state statute to be a "brief document which is designed to set out the basic facts necessary to determine whether an EIS�ls required for a proposed action." The purpose of the EAW process is to disclose information about potential environmental impacts -of the project. The EAW process is not an approval process. The information disclosed in the EAW process has two functions: (1) It is used to determine whether an EIS is needed; and (2) It indicates how the project can be modified to lessen its environmental impact - such modification may be imposed as permit conditions by regulatory agencies. The information disclosed comes from three sources: (1) the EAW itself; (2) comments received on the EAW; and (3) response made to comments received on the EAW. However, the EAW itself is generally the most important source of information THE EAW PROCESS INVOLVES FOUR MAJOR STEPS: STEP 1 - the proposer of the project supplies data necessary for the completion of the EAW to the Responsible Governmental Unit (RGU),. The RGU in this situation is the City of Hopkins. STEP 2 - The RGU prepares the EAW STEP 3 = 30 -day public comment period STEP 4 - The RGU responds to the comments received and makes a decision on the need for an EIS based on the EAW, comments received, and the responses to the comments. The RGU and other units of government may require modification to the project to mitigate environmental impacts as disclosed through the EAW process. Standard and Criteria for the Decision of the need for an EIS. The standard for the decision is: " Does the project have the potential for significant environmental effects ?" In answering this question the City must compare the impacts which may be reasonably expected to occur from the project with the following criteria: 1. Type, extent, and reversibility of environmental effects. 2. Cumulative potential effects of related or anticipated future projects. 3. The extent to which environmental effects are subject to mitigation by ongoing public regulatory authority. H LI 4. The extent to which environmental effects can be anticipated and controlled as a result of other environmental studies undertaken by other public agencies or the project proposer, or of environmental impact statements previously prepared on similar projects. Purpose of a EIS if ordered The purpose of an EIS is to provide information for governmental units, the proposer of the project, and other persons to evaluate proposed projects which have the potential for significant environmental effects, to consider alternatives to the proposed project, and to explore methods for reducing adverse environmental affects. An E.I.S. has never been done for a project of this type. An E.I.S. can take many months and can be costly because of the data that needs to be collected. The proposer of the project generally pays the costs for an E.I.S.. o What is the background for this E.A.W.? Chronoloav of Events • 1. March 26, 1991 - Zoning and Planning Commission approves conditional ,use permit to construct 12 townhomes. 2. March 28, 1991 - petition for an EAW received for Ramsgate Townhomes 3. April 2, 1991 - City Council ordered preparation and submission of E.A.W. 4. May 17, 1991 - E.A.W. distributed to required agencies 5. May 29, 1991 - Notice of E.A.W. availability published in local newspaper 6. May 27, 1991 - Notice of E.A.W. availability published in E.Q.B. Monitor. Beginning of 30 day comment period. 7. June 26, 1991 - Expiration of 30 day comment period. o What is the project site and description? A. Project Name - Ramsgate Townhomes B. Proposer - Mark C. Jones C. Project Location - Southwest corner of Hiawatha Avenue and Cambridge Street D. Reason for E.A.W. preparation - 'discretionary 0 E. Total Project Area - 1.54 acres F. Number of proposed residential units - 12 G. Brief description of site - The property in question is undeveloped. The property currently is a wooded site. The site is surrounded by multifamily residential to the west, single family homes to the south and east and State Highway 7 to the north. H. Brief description of the project - Ramsgate townhomes consists of twelve townhomes located in two six unit buildings. The townhomes will be two story, three bedrooms with a two car tuck -under garage. Surface parking for two additional vehicles will be provided for on the double width driveway for a total of four parking spaces per unit. Access will be from Cambridge Street rather than from Hiawatha Avenue. o what agencies /indivduals submitted written comments? Written comments were received from four indivdual /agencies. The written comments were received from the following: State of Minnesota Department of Natural Resources Metropolitan Council - Larry McNeff, Hopkins resident - Minnesota Historical Society o What -were the comments received during the 30 day comment period? A. Historical, Archaeological, etc. o Comments - Comments received through the E.A.W. process indicated that the project contained no known historic or archaeological sites. Comments also indicated if federal funding were involved in the project in some way, that certain additional review requirements may be necessary. These comments were received by the Minnesota Historical Society. o Response - In response to these comments, the City will inform the developer that if the developer receives federal assistance for the project, the requirements of Section 106 of'the National Historic Preservation Act of 1966 and 36CFR800 must be met by the developer. a B. Cover Types. There was an error made on the cover types for before and after the development. The correct totals are as follows: Wooded Forest Urban /suburban lawn landscaping Impervious surface As stated in EAW Correct Figures before after before after 1.54 0 1.16 0 0 .734 0 .734 .38 .80 .38 .80 This change does not have any significant impact on the conclusion of the EAW. C. Fish, Wildlife, and Ecologically Sensitive Resources o Comments - Comments received through the E.A.W. process by Larry McNeff indicated there are other small animals on the site. o Response - There may be other animals on the site. However in the staffs observations there were no other animals visible other than birds. o Comments - Comments received through the E.A.W. process by Larry McNeff indicated a concern for the trees being removed. o Response - The proposed development is proposed to retain 18 oak trees. There will be 23 new deciduous, 18 evergreen, and 88 other shrubs planted to replace the trees removed. The proposed trees retained and planted exceed the ordinance requirements. o Comments - The DNR noted that if there is damage to the roots or bark of the remaining oak trees, it may result in their eventual loss. D. Physical Impacts on Water Resource. o Comments - Comments received through the E.A.W. process by Larry McNeff expressed a concern about the impact of the project to the drainage ditch along Highway 7. o Response - The increased runoff will be stored in the retention pond and released at pre - construction rates in accordance with -the rules of the Minnehaha Creek Watershed District. E. Water Ouality - Surface Water Runoff. This project will generate storm water runoff which will be served in large part by a retention pond proposed to be located on the north end of the site. This water will be released at pre- construction rates. o Comments 1 - Comments received through the E.A.W. process by Larry McNeff expressed a concern for the history of flooding in the area. o Response - Dale Folen of RCM has reviewed the site plan for the Ramsgate Townhomes. In a letter dated March 26, 1991 he stated the following "The proposed pond will hold the expected increased runoff use to development and replace the volume of the existing local low area which would be filled be construction." F. Sanitary Sewer. The proposed development will generate approximately 3000 gallons of domestic waste sewage per day. This waste will flow into an existing sanitary main in Hiawatha Avenue which in turn is connected to the 33" MWCC Hopkins Interceptor. o Comments - Comments received through the E.A.W. process by Larry McNeff indicate sewer problems in the area. o Response - In response to these comments, the City proposed to reroute the existing sanitary flow from the Ramsgate Apartments to a new connection. This will remove the Ramsgate flow from the Hiawatha system to alleviate any existing or future problems. This will remove 360 units from the Hiawatha system and add the 12 townhomes. The City has initiated a project to correct existing sanitary sewer capacity problems along Hiawatha Avenue. However, this project has been put on hold due to the fact that the City has not been able to obtain up to this point the necessary easements form Ramsgate Apartment to allow for the extension of a new line. G. Metropolitan Council The E.A.W. was reviewed by the Metropolitan Council staff. The staff determined the following: "The staff review has concluded that the EAW is complete and accurate with respect to regional concerns and raises no major issues of consistency with Council policies. An EIS is not necessary for regional purposes. H. 'Traffic o Comments - Comments received through the E.A.W. process indicate that 144 -288 trips will be generated. This number of trips was estimated by Larry McNeff. o Response - Benshoof and Associates studied the traffic for the proposed development. It was estimated that an additional 108 trips will be generated by the proposal. x I. Vehicle- related air emissions o Comments - Comments received through the E.A.W. process by Larry McNeff indicated that it is not necessary to -have traffic congestion to cause a significant decrease in air quality. o Response - The E.A.W. only addresses air quality due to traffic congestion. Since there is no expected traffic congestion with this project, (based upon findings from the traffic study) there is no expected decrease in air quality. o What are staff's conclusions as related to the comments received? The staff feels the EAW document adequately address all of the environmental issues as relates to this project. The comments that were received did not bring up any issues that have not been addressed in the EAW. Based upon the findings of the EAW, the staff does not feel that the project will create any significant environmental impacts. o What were the noise levels at various locations around the site? At the July 16 City Council meeting, the Hiawatha residents expressed a concern about the noise level to the neighborhood once the trees are removed. In response to this concern, staff contacted the Minnesota Pollution Control Agency requesting noise monitoring at various locations around the subject site. On July 30, 1991, at approximately 9:00 a.m., Rebecca Niedzielski of the Minnesota Pollution Control Agency did noise monitoring at several places around the subject property. Attached is a map of the locations and noise levels. None of the readings exceeded the Hopkins Zoning Ordinance Standards and the Minnesota Pollution Control Agency Noise Standards. The noise standard both for Hopkins and the Pollution Control Agency's rules is 65 decibels for the daytime. None of the readings exceeded 60 decibels. Attached are the Hopkins Zoning Ordinance standards and the Minnesota Pollution Control Agency Noise Standards. On the attached site plan showing the locations and noise levels, at some locations there are two readings. There are two readings in some locations because there was a difference in the decibel level if there was automobile traffic. In the areas further to the south, the traffic noise was not a factor. Alt rnatives. 1. Approve the resolution determining there are no significant environmental impacts and that an E.I.S. r is not needed. Under this action the project can proceed provided all necessary permits and approvals are secured. 2. Make a finding that there is significant environmental impacts. Such a determination will require that an E.I.S. is needed for the project. An E.I.S. will have to be completed before the project is approved. 3. Continue for further information. If the City Council indicates more information is needed, the item should be continued. The City Council can hold a public a hearing to gather more information. By E.Q.B. rules this must be done by July 26, 1991.

Land Use Describe current and recent past land use and development on the site and on adjacent lands. Discuss the compatibility of the project with adjacent and nearby land uses; indicate whether any potential'conflicts involve environmental matters. Identify any potential environmental hazard due to past land uses, such as soil contamination or abandoned storage tanks. The subject property is vacant and has always been a vacant parcel. The adjacent property on the east and south are single family homes. The property to the west is multiple family. To the north is State Highway 7. The site when developed will consist of 12. townhomes, two six unit buildings. The surrounding area on three sides of the site is either high density residential or single family homes. The proposed land use on the subject property serves as a transition from high density multiple family to single family. 10. Cover Types Estimate the acreage of the site with each of the following cover types before and after development (before and after totals should be equal): Before After Before After Types 2 to 8 0 0 Urban /Suburban 0 Wetlands .734 Lawn Landscaping Wooded /Forest 1.54 0 Impervious Surface .38 Brush /Grassland 0 0 .80 Other (describe) 0 opland 0 0 3 C. Will the project require connection to a public water supply? R Yes 0 No If yes, identify the supply, the DNR water appropriation permit number of the supply., and the quantity to be used. Yes. Connection will be made to the municipal water supply, specifically well #5. The Minnesota Department of Conservation permit number issued December 12, 1967, is 67- 1287G. The water usage per day for this development is estimated to be 4320 gallons. 14. Wat r- related Land Use Management Districts Does any part of the project site involve a shoreland zoning district, a delineated 100 -year flood plan, or a, state or federally designated wild or scenic river land use district? 11 Yes Im No If yes, identify the district and discuss the compatibility of the project with the land use restrictions of the district. 15. Water Surface Use Will the project change the number or type of watercraft on 'any water body? O Yes ONO If yes, indicate the current and projected watercraft usage and discuss 0 any potential overcrowding or conflicts with other users or fish and wildlife`resources. 16. Soils Approximate depth (in feet) to: Ground water: minimum V to 7 ' average 14' Bedrock: I minimum unknown average beyond soil boring depths Describe the soils on the site, giving SCS classifications, if known. (SCS interpretations and soil boring logs need not be attached.) SCSM - silty sandy clay SM with CL - silty sand with of clay SP - sand SP - with CL - sand with seams of silty clay SP with SM -SC - sand with some gravel seams of silty clay 17. Erosion and Sedimentation Give the acreage to be graded or excavated and the cubic yards of soil to be moved: acres 1.50 ; cubic yards 5000 Describe any steep slopes or highly erodible soils and identify them on the site map. Describe the erosion and sedimentation measures to be used during and after construction of the project. The existing slopes vary up to a 40% slope. (2- 1/2:1) The proposed slopes will vary from 1% to 1:1 slopes at the retention' pond. The steep slopes around the pond will be riprapped. Other site slopes and landscaped areas will be sodded. Erosion and sedimentation preventive 5 a The City has chosen a solution to capacity problems by rerouting a portion of the existing flow to a new connection with the 33" MWCC Hopkins Interceptor. More specifically this involves removing all of the current sanitary sewer flow from the Ramsgate Apartments from the Hiawatha Avenue system. This would require 200 feet of existing 8 -inch sanitary sewer to be relaid and the additional installation of 460 feet of new 8 -inch sanitary to its connection with the 33" interceptor located near the Ramsgate Apartments in Lake Street N.E. Elimination of these flows from the Hiawatha Avenue 'system would decrease flow rates at critical flat grade locations in Hiawatha Avenue to levels compatible with system capacity. The connection of the proposed townhouse units to the Hiawatha Avenue sanitary sewer could then be permitted. 20. Ground Water - Potential for Contamination a. Approximate depth (in feet) to ground water: 3'- 7' minimum; __L4 average. b. Describe any of the following site hazards to ground water and also identify them on the site map: sinkholes; shallow limestone formations /karst conditions; soils with high infiltration rates; abandoned or unused wells. Describe measures to avoid or minimize environmental problems due to any of these hazards. 0 NONE c. Identify any toxic or hazardous materials to be used or present on the project site and identify measures to be used to prevent them from contaminating ground water. NONE 21. Solid Wastes; Hazardous Wastes; Storage Tanks a. Describe the types, amounts, and compositions of solid or hazardous wastes to be generated,- Ancluding animal manures, sludges and ashes. Identify the method and location of disposal. For projects, generating municipal solid waste indicate if there will be a source separation plan; list type(s) and how the project will be modified to allow recycling. Construction waste from 12 townhomes, the amount of waste would be' about 400 cubic yards. The construction waste would be disposed at Dem -Con Landfill, Inc., 3601 West 130th Street Louisville Township. Normal household waste generated will be handled by the City garbage service. The City contracts with Reuter to dispose of the City garbage. Reuter processes the garbage for various uses. This garbage does not going a landfill. Approximately 781 pounds of garbage is generated per person per year. 7 24. stationary source air emissions Will the project involve any stationary sources of air emissions (such as boilers or exhaust stacks)? ® Yes 0 No If yes, describe the sources, quantities, and composition of the emissions; the proposed, air pollution control devices; the quantities and composition of the emissions after treatment; and the effects on air quality. Each townhome will be heated with a gas forced air furnace that will have a chimney flue exhausting through the roof area. 25. Will the project generate dust, odors, or noise during construction and /or operation? 1 Yes NO If yes, describe the sources, characteristics, duration, and quantities or intensity, and any proposed measures to mitigate adverse impacts. Also identify the locations of sensitive receptors in the vicinity and estimate the impacts on these receptors. 27. Will the project create adverse visual impacts? (Examples include: glare from intense lights; lights visible in wilderness areas; and large visible plumes from cooling towers or exhaust stacks.) Yes 0 140 If yes, explain. W Due to the small size of the project a minor amount -of dust may be generated during grading and construction. Grading will take place during the fall months, with most construction being during the winter months. During operation noise level would be that normal for 0 habitational dwellings 26. Are any of the following resources on or in proximity to the site: a. archaeological, historical, or architectural resources? Yes b. prime or unique farmlands? No O Yes c. designated parks, recreation areas, or trails? No 0 Yes ® d. scenic views and vistas? No E Yes e. other unique resources? No Yes ONO If any items are answered Yes, describe the resource and identify any impacts on the resource due to the project. Describe any measures to be taken to minimize or avoid adverse impacts. The site has about 70 oak trees 6" and larger, 18 of the existing oaks will remain after construction. Many new plantings will also be added. See answer to lib regarding the number of trees and other plantings added to the site. 27. Will the project create adverse visual impacts? (Examples include: glare from intense lights; lights visible in wilderness areas; and large visible plumes from cooling towers or exhaust stacks.) Yes 0 140 If yes, explain. W 7 , 1 1 l d. If a, b, or c were marked Yes, discuss any cumulative environmental impacts resulting from this project and the other development. In 1969 the building plans for the adjacent apartment complex identified this area for townhomes. In 1972 a conditional use permit was granted for 22 townhomes, these townhomes were never constructed. 31. oth r Potential Environmental Impacts If the project may cause any adverse environmental impacts which were not addressed by items 1 to' 28, identify and discuss them here, along with any proposed mitigation. NONE 32. Summary of Issues (This section need not be completed if 'the EAW is being done for EIS scoping; instead, address relevant issues in the draft Scoping Decision document which must accompany the EAW.) List any impacts and issues identified above that may require further investigation before the project is commenced. Discuss any alternatives or mitigative measures that have been or may be considered for these impacts and issues, including those that have been.-or may be ordered as permit conditions. 0 This development consists of the construction of 12 townhomes and a parking lot for 24 cars. There is parking on the subject site now, which will be moved to the south end of the site. The development will remove most of the existing trees on the site. 18 trees will be retained plus 129 new plantings will be added to replace the plantings removed. There currently exists an over - capacity problem with the sanitary sewer in the area. However, the ganitary,,sewer is in the planning stages of being re- routed to fix thiq existing problem. The surface water runoff will be increased due to the construction of the townhomes and the impervious surfaces. The increase runoff will be stored in the retention pond located on the north side of the site will be released at pre- construction levels. The impact on Minnehaha Creek will be insignificant. The impact to the roadways has been reviewed. Because of the small increase in traffic it has been determined that there will be no affect on the traffic flow on the nearby roadways. It also has been determined that Hiawatha will not have to be widened given there are parking restrictions along Hiawatha. 0 11 N W E 0 o _ ..� H7 Dayton ' ".b Champlin i I � i � � 2 O � NORM a o� HENNEPIN COUNTY Minn sota Lege .� — ® Q ^� Tangl Sch � it JI ,� / Jr � I I �1� � 1 o (j • ( (��o�� S , \ I .J)� -- 7� _ vfa ,nr e,rr 1 1� j' � L( r �,• c„ SJI I r r94 o c /� . 11Y �•\ � � • V `I ` PLl/d � la t o -sa CG; 1 t �4.� .r 7 HMI 1 _ ,111 Nor i �� Ji IQ . �- 'I � �� 1� � ,� •�sam 0 gPY�i• , , � r •: e ; �, : ,_ a �� �� . • J Gravel'Plt >3 vl 28TR 1 i .sr �(� •r � II (� �s�` P rk r l i( 1 I 1 rl i- f W.

Benshoof & David RE: Response to Question 22, EAW for Ramsgate Townhouses PURPOSE The purpose of this memorandum is to present the results of a study you requested regarding the Ramsgate Townhouses development. Specifically, it provides responses to Question 22 of an EAW being prepared for the development which will be located at the southwest corner of Cambridge St. and Hiawatha Ave. in the City of Hopkins. It is our understanding that the project will involve the construction of 12 townhouses just east of the existing Ramsgate Apartment Complex. To provide adequate responses to the requirements of Question 22, the focus of our study includes the number of on -site parking spaces provided, the estimated average daily and peak period traffic volumes generated by the development, the effect of these traffic volumes on nearby roadways, and any traffic improvements necessary to address such effects. Y PARKING SPACES ' As shown in the proposed Ramsgate Townhouses site plan, a total of 48 parking spaces will be provided to serve residents and guests. Of this total, 24 will be provided in 12 two -car garages located beneath the townhouses and 24 will be surface parking spaces located along the west edge of the site. TRAFFIC VOLUMES To gain a better understanding of current traffic conditions near the Ramsgate Townhouses site, existing daily traffic volume counts were conducted by City of Hopkins staff during the period April 26 -30, 1991. These counts were taken on Cambridge St., just east of Hiawatha Ave., and on Hiawatha Ave., just south of Cambridge St. It is expected that any impacts related to traffic generated by this development will occur mainly on these roadways. w ' l• � A Ms. Anderson -2- May 8, 1991 In order to identify changes in traffic volumes on nearby roadways, an estimate of site - generated traffic volumes must be established. As such, trip generation analyses were conducted for the development using rates found in the Institute of Transportation Engineers publication, Trip Generation 1991. Applying these rates to the proposed development of 12 townhouses, the resultant trip generation projections are as follows: Trips Generated by Ramsgate Townhouses Development TIME PERIOD IN OUT TOTAL A.M. Peak Hour 2 8 10 P.M. Peak Hour 7 4 11 Daily 54 54 108 Based on the relationship of the proposed development to the roadway system it is our expectation that about 108 daily trips would be generated by the development. In our judgement, about 80 percent of the 108 total trips (87 trips) will use Cambridge St. east of the site, 15 percent (16 trips) will use Cambridge St. west of the site, and 5 percent (5 trips) will use Hiawatha Ave. Accounting for existing and development trips, the resultant total volumes on Cambridge St. and Hiawatha Ave. are as follows: EXISTING DAILY POST - DEVELOPMENT LOCATION VOLUME DAILY VOLUME Cambridge St. east of Hiawatha Ave. 2480 2567 Hiawatha Ave. south of Cambridge St. 85 90 EFFECTS ON NEARBY ROADWAYS In view of the relatively small increase in both daily and peak period traffic volumes expected to result from the Ramsgate Townhouses development, it is our judgement that the development will not adversely affect traffic flow on nearby roadways. Cambridge St. has ample capacity to accommodate the expected 3,5 percent increase in daily traffic volumes. The presently low volume on Hiawatha Ave. will not be significantly altered because no parking or access for the development will be provided on Hiawatha Ave. Given the above findings, we have determined that no improvements to the roadway syystem will be needed in order to effectively accommodate traffic generated by the proposed development. An additional concern regarding available roadway width on Hiawatha Ave. was also addressed. It is our understanding that on- street parking recently has been restricted along Hiawatha Ave. As such, it is our judgement that the current roadway width of 22 feet can adequately accommodate the expected post- development traffic and provide sufficient access for emergency vehicles. It should be noted that this'observation is valid only if the parking restriction along Hiawatha Ave. remains in place and is enforced. 0 g FINDINGS OF FACT RAMSGATE TOWNHOMES I. Project and Site A. Project Name - Ramsgate Townhomes B. Proposer - Mark C. Jones C. Project Location - Southwest corner of Hiawatha Avenue and Cambridge Street D. Reason for E.A.W. preparation - discretionary E. Total Project Area - 1.54 acres F. Number of proposed residential units - 12 G. Brief description of site - The property in question is undeveloped. The property currently is a wooded site. The site is surrounded by multifamily residential to the west, single family homes to the south and east and State Highway 7 to the north. H. Brief description of the project - Ramsgate townhomes consists of twelve townhomes located in two six unit buildings. The townhomes will be two story, three bedrooms 'kith a two car tuck -under garage. Surface parking for two additional vehicles will be provided for on the double width driveway for a total of four parking spaces per unit. Access will be from Cambridge Street rather than from Hiawatha Avenue. II.' Type, Extent and Reversability of Environmental Effects A. Historical, Archaeological, etc. o Comments - Comments received through the E.A.W. process indicated that the project contained no known historic or archaeological sites. Comments also indicated if federal funding were involved in the project in some way, that certain additional review requirements may be necessary. These comments were received by ,the Minnesota Historical Society. o Response - In response to these comments, the City will inform the developer that if the developer receives federal assistance for the project, the requirements of Section 106 of the National Historic Preservation Act of 1966 and 36CFR800 must be met by the developer. 0 B. Cover Types. There was an error made on the cover types for before and after the development. The correct totals are as follows: This change does not have any significant impact on the conclusion of the EAW. C. Fish, Wildlife, and Ecologically Sensitive Resources. o Comments - Comments received through the E.A.W. process by Larry McNeff indicated there are other small animals on the site. o Response - There may be other animals on the site. However in the staffs observations there were no other animals visible other than birds. o Comments - Comments received through the E.A.W. process by Larry McNeff indicated a concern for the trees being removed. o Response - The proposed development is proposed to, retain 18 oak trees. There will be 23 new deciduous, 18 evergreen, and 88 other shrubs planted to replace the trees removed. The proposed trees retained and planted exceed the ordinance requirements. o Comments - The DNR noted that if there is damage to the roots or bark of the remaining oak trees, it may result in their eventual loss. D. Physical Impacts on Water Resource. o Comments — Comments received through the E.A.W. process by Larry McNeff expressed a concern about the impact of the project to the drainage ditch along Highway 7. o Response - The increased runoff will be-stored in the retention pond and released at pre- construction rates in accordance with the rules of the Minnehaha Creek Watershed District. E. Water Quality - Surface Water Runoff. This project will generate storm water runoff which will be served in large part by a retention pond proposed to be As stated in EAW Correct Figures before after before after Wooded Forest 1.54 0 1.16 0 Urban /suburban 0 .734 0 .734 lawn landscaping Impervious surface .38 .80 .38 .80 This change does not have any significant impact on the conclusion of the EAW.

E. Water Quality - Surface Water Runoff. This project will generate storm water runoff which will be served in large part by a retention pond proposed to be c y. located�on the north end of the site. This water will be released at pre- construction rates. o Comments - Comments received through the E.A.W. process by Larry McNeff expressed -a concern for the, history , of flooding in the area. o Response - Folen of RCM has reviewed the site plan for the Ramsgate Townhomes. In a letter dated March 26, 1991 he 'stated the following "The proposed pond will hold the expected increased runoff use to development and replace the volume of the existing local low area which would be filled be construction." F. Sanitary Sewer. The proposed development will generate approximately 3000 gallons of domestic waste sewage per day. This waste will flow into an existing.sanitary main in Hiawatha Avenue which in turn is connected to the 33" MWCC Hopkins Interceptor. o Comments - Comments received through'the 'E.A.W. process by Larry McNeff indicate sewer problems.in the area. o Response - In response to these comments, the City proposed to reroute the existing sanitary flow from the' Ramsgate .Apartments to a new connection. This will remove the Ramsgate flow from the Hiawatha system to alleviate any existing or future problems. This will remove 360 units from the Hiawatha system and add the 12 townhomes. G. Metropolitan Council. The E.A.W. was reviewed by' the Metropolitan Council staff. The staff determined the following: "The staff review has concluded that the EAW is complete and accurate with respect to regional concerns and raises no major issues of consistency with Council policies. An EIS is not necessary for_regional,purposes. H. Traffic. o Comments - Comments received through the E.A.W. process indicate that 144 -288 trips will be 'generated.' This number of trips was estimated by Larry McNeff. o Response - Benshoof and Associates studied the traffic for-the proposed development. It was estimated that an additional 108 trips will be generated by the proposal., 4 I. Vehicle- related air emissions. o Comments - Comments received through the E.A.W. process by Larry McNeff indicated that it is not necessary to have traffic congestion to cause a signif icant I decrease in air quality. o Response - The E.A.W. only addresses air quality due to traffic congestion. Since there is no expected traffic congestion with this project, (based upon findings from the traffic study) there is no expected decrease in air quality. • • CITY OF HOPKINS Hennepin County, Minnesota RESOLUTION 91 -91 A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF HOPKINS ADOPTING FINDINGS OF FACT PERTAINING TO THE ENVIRONMENTAL ASSESSMENT WORKSHEET FOR THE PROPOSED RAMSGATE TOWNHOMES AND DETERMINING THAT AN ENVIRONMENTAL IMPACT STATEMENT IS NOT REQUIRED TO BE COMPLETED FOR SAID PROJECT.
