Orrin Thompson - U. S Home Corporation r( The developer has provided for park dedication of the gas pipeline easement area as recommended by City staff and previously reviewed by the Park Committee. The easement area totals 5.4 acres and at 50% credit would result in a 2.7 acres park dedication. Therefore, cash in lieu of 5.3 acres of land would need to be pro- vided to satisfy the total park dedication requirements relative to this plat. The cash dedication requirement has been calculated as follows: 45 Single Family units - @ $240 - $10,800 152 Doubles @ $200 = 30,400 J Total Cash for Entire Development $41,200 The land dedicated equals 33 1/3% of the total require- ment or $13,720. Therefore, cash dedication in the amount of $27,480 will be required with final plat approval, to be placed in an escrow account for the following reasons Staff would like to have the authority to review the landscape plan when it is available and possibly request the installation of additional land xi scaping materials to buffer the trail area with a re- sultant reduction in this cash dedication requirement. Also, it appears that Mr. Thompson may also be soon platting land in Section 32, directly west of this parcel, and he has expressed a willingness to combine the park land dedication requirements of the two plats to.create a usable park area within that plat west of Johnny Cake Ridge Road if the City ' so desires. The Section 33 neighborhood study done pre- viously in conjunction with the Beacon Hills plat designates land to the east of this parcel to be de- dicated with future platting to satisfy neighborhood park needs. City Attorney Hauge has recommended that the trail dedication be in fee title rather than as a trailway to be consistent with previous all purpose trail dedications. I Additional information on the remaining develop- ment proposals will be provided at the meeting. Background Information Page 3 IV. PARK DEPARTMENT BUSINESS 1. Rahn Thomas Trail The High Line Trail was constructed two weeks ago from Woodgate Lane to near the new school. Unfortunately, two horses rode k of a mile on the newly laid asphalt and made deep impressions. Also the July 23 rainstorm caused washouts in two areas. Repairs to the washouts and the remaining asphalt work should be completed by the week of August 6th, 1979. 2. Contract #4 The contractor still has a number of items to complete before final inspection of this project can be made. 3. FY 1979 Grant The contract for the Federal portion of the grant for park land in Section 9 has been received and will be presented to the City Council for approval at the August 7, 1979 City Council meeting. VI. OLD BUSINESS E Zachman Homes and Tilsen Homes development proposals 3 will be further reviewed at a staff meeting, August 14, i 1979. J F PARK COMMITTEE AGENDA BACKGROUND INFORMATION August 2, 1979 II. Report From City Council Meeting The Park Committee's recommendation on the Wind- tree plat was approved by the City Council subject to dedication of the adjacent park land from Gopher-Eagan. Park Director Schmidt has written requesting early dedication of the proposed parcel but as yet has re- ceived no reply. An arena proposal was presented to the Council and the City Administrator was directed to prepare a feasibility study and report back to the Council. A.special -City Council meeting will be held' August 9, 1979at - - at the City Hall to further consider this- -tee-DEVELOPMENT PROPOSALS A. Thomas Lake Heights (Blackhawk PUD) Park dedication for this plat has already been committed under the Blackhawk Park PUD with land proposed to be dedicated in the future around Heine Pond, around Blackhawk Lake, and to expand Thomas Lake Park. The NSP easement area from the west edge of Evergreen Park to the west boundary of the Blackhawk Park PUD has been previously dedicated in fee title, to allow,for the construction of the High Line Trail. The trail area amounts to 12.12 acres of land with 50% credit given for a park dedication credit of 6.6 acres, 65 acres are included in this plat and 15 acres were previously sold to the school, bringing the total to 80 acres. T refore cash should be lace in es w in 1 u of 1.4 acre of land. Staff wil dete• ine t requi d amount. Outlot B between lots 21 and 2 from the Balsam Lane cul de sac to the trail coming from the Heine Pond Addition has been provided as previously re- quested by the Park Committee.

Internal sanitary sewer and water main distribution systems will be designed and/or approved ` by the City prior to their installation. Access to this plat will be provided by the presently under construC n x Thomas Lake Road collector street. This plat shows seven (7) cul-de-sacs of which three (3) require the approval of a variance to the 500 foot length according to our present subdivision ordinance. The Engineering Division has reviewed the topography in conjunction with the proposed . street layout and find that these excessive length cul-de-sacs are un- avoidable due to elevation differentials. Greenwood Lane is recammerded to be redesigned to eliminate the small "bubble" cul-de-sac an the northwst = oorner. It is also felt that with a slight redesign and minor grading that the Balsam Point cul-de-sac could be eliminated by continuing it to the south and cotumcting with Greenwood Lane. Staff would like to request direction from the. Planning Cmmission and the Council in the extent of scrutinizing that should be done in relationship to the elimination of cul-de-sacs in ©rder to alleviate future maintenance problem for the general tax paying , public. F EASEMENTS AND R.O.W. All easements and rights-of-way as indicating on the preliminary Plan submitted dated May 30, 1979 is acceptable according to current City requirements. Drainage and utility easements adjacent to property lines as indicated on same preliminary plat is also in accordance with City standards. Appropriate drainage and utility easements incorporating drainage basins must be reviewed and approved by Staff prior to final plat approval. a p . lbomas lake Heights Addition June 18, 1979 Page 2 DRAINAGE - Drainage for this plat is proposed to be handled by a series of on-site drainage basins which will interconnect with the presently under construction The mas Lake to Blackhawk Lake trunk storm sewer system. A series of internal storm sewer laterals and catch basins will be required during the utility grading design phase. Prior to final plat approval it is recommended that a house and drainage plan showing individual lot drainage patterns and proposed elevations be submitted and approved by the City. CONSIDERATIONS FOR APPROVAL The following omrents should be considered in the final approval of the above referenced plat: 1.

RLNKLE, CITY PLANNER Applications Submitted 1. An application has been submitted to rezone 80 acres of A, Agriculturally zoned land to R-1, Residential Single District--38 acres; and, R-3, Residential Townhouse District-42 acres. 2. The second application is for a preliminary plat (Johnny Cake Ridge) which would consist of approximately 80 acres and would contain 45 single family lots and 152 townhouse units. Comments 1. The proposed plat appears to be well designed. Covington Lane has been extended through the proposed plat from Beacon Hills to Johnny Cake Ridge Road. The plat also has continuity with Beacon Hills with single family abutting single family. The developer had also picked up the remainder of the cul-de-sac from the Beacon Hills plat. 2. According to the Eagan Land Use Guide, this parcel should develop as an R-2 land use; mixed residential 3-6 units per acre. The proposed development is mixed residential with a gross density of 2.46 units per acre. The following table is a breakdown) of the density for Johnny Cake Ridge: LAND USE ACRES UNITS UNITS/ACRE UNITS ALLOWED IN ORDINANCE-52 Rl 31.8 45 1.2 3.6 units/acre R3 34.4 152 4.4 7.2 units/acre R.O A. 8.6 -0- -0- -0- Park 5.4 -0- -0- -0- f 3. There are a few single family lots which do not meet the 85 foot width requirement at the 30 foot setback line. There are also a few lots which do not meet the 12,000 square foot area requirement. This could be accomplished by altering a few lot lines. The quads are being platted as individual units with commn open space between the units. 'The quads meet all the requirements of the R3 zoning district. 4. The developer is proposing to dedicate the Williams Brothers pipelines approximately a 60 foot area all the way through the plat for an all purpose • U.S. HOME CORP. JULY 26, 1979 i PAGE 2 Trail. This is in conformance with the park department plans for a north/south trail. The trail will also provide a buffer between the quads and the single family lots. If approved, the plat should be subject to the following conditions: 1. A trot lot should be provided within the quad area to provide a play area for the pre-schoolers. 2. The Homeowners Association should be established for the quad area and • the bylaws should be reviewed by the City prior to submission of the final plat. 3. The plat should be subject to the comments of the Dakota County Plat Commission because the proposed plat abutts two County roads. 4. Sidewalks should be Provided on Covington Lane and Johnny Cake Ridge Road in accordance with Eagan Sidewalk Policy. 5. A landscape plan for the townhouse should be approved by the City Staff. 6. All single family lots should contain 12,000 square feet and have an 85 foot width at the 30 foot setback line unless specific variances are requested. 7. Cul-de-sac B would require a 50-75 variance because cul-de-sac B exceeds the 500 foot length requirement. 8. All drainage and utility easements should be approved by the City Engineer. ENGINEERING RBCOMMEZATIONS 1. Sufficient right-of-way be dedicated to provide for a 50 foot half right- of-way from the existing center line of Johnny Cake Ridge Road and a 75 foot half right-of-way be dedicated adjacent to Cliff Road. 2. An 80 foot right-of-way be dedicated for Covington Lane with 60 foot right- . of-way being dedicated over the remainder of the plat or streets. 3. Ten foot drainage and utility easement be dedicated adjacent to all riot- of-way and centered over all common property lines. 4. Two cul-de-sac streets be looped in the northwest corner of this plat. 5. Bikeway along the east side of Johnny Cake Ridge Road be constructed as a part of the street project and be the responsibility of this development. 6. Grading and drainage plan indicating the lot corner elevations and proposed house elevations be submitted and approved prior to final plat approval. 7. Sufficient easements be dedicated as required the Engineering Department for drainage basins and any utility looping down cannon lot lines. 8. Before any excavation can begin, the required storm sewer lift station and subsequent oulet storm sewer system from the pond in the northeast corner of this plat must be awarded by Council. MEM:) TO: ADVISORY PLANNING CObMISSION AND DALE C. 1WTKLE, CITY PIANNEP. FROM: THOMAS A. COLBERT, DIRECTOR OF PUBLIC WORKS DATE: JULY 26, 1979 SUBJECT: PREL LvMzARY PLAT JOHNNY CAKE RIDGE (U.S. HCME CORPORATION) The Engineering Division of the Public Works Depart-nent has the following consents to offer in regards to consideration of the above referenced plat: UTILITIES Water main is available along Cliff Road, Johnny Cake Ridge Road and from the Beacon Hill plat immediately to the east of sufficient size to provide water service for this plat. Trunk sanitary sewer is available in the southeast corner of this plat of sufficient size and depth to handle this proposed development. STREETS During preliminary discussions with the developer, revisions were made to provide for a loop street from Covington to the north/south street eliminating the originally proposed two cul-de-sacs. Because this plat is trangressed by the Williams Brothers pipeline installed to a minimum depth,there is approximately only two crossing that are feasible for any road construction. These are shown in the layout presented under the date of 7/9/79. Because of this pipeline and the existing topography, the cul-de-sac on the south third of this plat is unavoidable and best designed to serve the existing residence. Discussion with the developer to eliminate the two cul-de-sacs in the northwest corner of this plat and provide a connection was not mutually agreed upon due to the developers concern to eliminate row type housing. The Staff's proposal to connect these two cul-de-sac streets would not result in the elimination of any buildable site. The developer indicates that his intention is to maintain and create the effect of more open space with the construction of these two cul-de-sacs. .The topography is such that the connection of these two cul-de-sacs is a feasible alternate if the Commission and Council so deem it to be necessary or desirable. Covington Lane is a proposed extension continuation of the east/west collector street previously platted urder the Beacon Hill plat. EASE ENTS/R.O.W. Sufficient right-of-way should be dedicated to provide for a 50 foot half right-of-way from center line of the existing Johnny Cake Ridge Road and a 75 foot half right-of- way adjacent to Cliff Road (County Road 32). A 60 foot wide trailway easement should be dedicated over the existing Williams Brothers pipeline easement to provide for a continuation of the City/County park and trailway system. Standard drainage and utility easements will be required adjacent to right-of-way and over all coffin property lines. Additional easements may be necessary upon the design of the sewer and water system and additional easement will be required for storm water ponding areas in the southeast corner of this plat. These will be determined prior to final plat approval. JOHNNY CAIN RIDGE JULY 26, 1979 PAGE 2 GRADING AND DRAINAGE Drainage for this area is intended to be handled through an internal storm sewer system and directed into the existing pond in the southeast corner of this plat. arfiER CONr' M Present plans provide for connection to the County park system further to the south of this plat fiat Cliff Road along the east side of Johnny Cake Ridge Road. As with the conditional approval of the plat immediately south of this (Brittany) consideration should be given to requiring the developer of this plat to install a bikeway system as a part of the street improvement project along the east side of Johnny Cake Ridge Road fran the south property line up to Cliff Road. A 5 foot concrete sidewalk will be required as a part of the street construction of Covington Lane due to its east/west collector status.

R UNKLE, CITY PLANNER 1 Applications Submitted { 1. An application has been submitted for a preliminary plat, Marotzke Addition, which would contain approximately 19.5 acres and consist of 4 lots. 2. The second application is for a variance for a cul-de-sac street to exceed the 500 foot required length. 3. The third application is for a variance to allow an undersize lot in an agricultural district. The lot would be 3 acres when an agricultural lot without utilities would require 5 acres. C nTnents 1. The proposed addition is directly east of the Halley's Addition which has been platted and zoned without any utilities. In platting areas where utilities do not exist could be classified as premature development and could hinder the long range planning for this area. 2. In order for mr. Marotzke to sell 5 acres of his land and obtain a building permit for a single family hone he has to have a 5 acre parcel which has 300 feet of frontage on a public street. In order to have a public street the property has to be platted and dedicate the street to the City. 3. in reviewing,the plat, the street should extend all the way across Lot 4 and have a terporary cul-de-sac. In the long range plans, Delaware Street will be connected to this proposed street. 4. The proposed plat will consist of three 5-acre lots and one 3-acre lot. 5. The land use guide indicates that this area should develop as R-2 (Mixed Residential) 3-6 units per acre. In platting the area in 5 acre lots may be premature but if designed correctly could develop in the future with the suggested density. EARL MAFDrZKE JUNE 25, 1979 r PAGE 2 If approved, the proposed plat should be subject to the following conditions: 1. A letter be signed by the owner that when utilities are available to the site he would not object to his fair share of the assessments. 2. That no building permits be allowed on Lot 1 until utilities are installed into this subdivision. 3. An overall plan be submitted to show how the area could be further subdivided in the future. 4. The road should be brought up to a standard that the City could except this road as a public street. 5. The proposed plat should be subject to park dedication requirements. 6. All grading, drainage and utility easements should be approved by the City Engineer. ROGINEERING FECONMENIDATIMS 1. Ten foot drainage and utility easement be dedicated adjacent to all right- of-way and centered over all cmmn property lines. 2. It is reamu ended that this plat not be approved until sufficient right-of-way has been obtained providing for a full 60 foot right-of-way access from T.H. 3 to the west edge of this plat. Also, a 30 foot half right-of-way should be dedicated adjacent to the easterly property line of this proposed plat and that the extension of the proposed cul-de-sac be continued to the east property line for the future connection. 3. It is reoattnended that this plat not be approved until such time as an inproved 9 ton designed road is ordered for inprovement from T.H. 3 to service this plat. 4.

The Council also granted approval for the time extension for the preliminary plat which consisted of 107.35 acres and contained 96 single family lots and 48 duplex lots. The council also directed the Planning Commission to review the plat because there have been same alteratiecns from the preliminary plat which was originally approved. The plat was received by the City too late to advertise for a public hearing. The developer also has a porbl.em with financing and timing of the project and has to show considerable advancement of the planned development by September 1, 1979 in order to retain ownership of the land. }s. z; The developer wishes to review the South Delaware Hills Planned Development with the Planning Commission on July 31, 1979. The Planning Commission would then be able to determine whether the changes in the planned development are minor and could be reviewed and approved or whether the changes are significant and should reschedule another public hearing to review the entire planned development. The area east of the porrb ng area has not changed from the original preliminary plat. The park' proposal also has not changed. The g ads--which have occurred jent. The new plan consists qppL -_t1~e_south and west portion . of rthe -.planned. -d.eve la of approximately-9 to-10 acres of additional land and contains 24 additional duplex lots--48 units; and one less single family lot for a total of 95 single family lots and 60 duplex lots. The original plan consists of 192 dwelling units and the new plan will consist of 239 duelling units. The only other change is the h. aligroent of the through street of the planned development. The street has been changed in order to have lots on both sides of the street rather than on the side of the street which was originally proposed located in the southwest portion of the plat. All in all, the uses have remained the same within the planned development but it has incorporated an additional 10 acres to the plat and has added 47 units to the proposed development.

MEMO TO: ADVISORY PLANNING COMMISSION . FROM: ROBERT W. ROSENE, CONSULTING CITY ENGINEER 1 DATE: July 25, 1979 j SUBJECT: DELAWARE HILLS ADDITION The Engineering Division of the Public fWorks xDepartment has the following com- ments on the above referenced proposed plat: any ~ ~ * i "t : ~ a ::a=i f~ GENERAL The proposed Delaware Hills Addition was originally approved in 1977. It con- sisted of a single family residential plat containing approximately 150 residential lots located east of State Trunk Highway 49 (Dodd Road) in section 12 of Eagan, r~ The proposed development also included property in Inver Grove Heights which was to be platted in large lots. The approved preliminary plat of Eagan was not carried out. It is now being resubmitted with minor changes in layout made possible by the acquisition of some additional land along the southern boundary of the proposed plat. x i . { _ • :$t STREETS ; The revised plan has improved the street layout by providing a new alignment made possible with the acquisition of additional land of the major east-west street. This street now has development on both sides where the original plan showed lots on only one side. The new layout provides a more efficient use of the street and utilities. Some changes in the development in Inver Grove Heights have made minor changes in the streets in the Eagan portion. However, they are not significant. J UTILITIES f~ ; r z Water service for this addition, as shown on the Water System Master Plan, will require a section of 24" diameter water trunk extending northerly from the existing trunk along T.H. 49 to the proposed addition. Eventually this line will connect to the trunk in place at T.H. 49 and Apollo Lane. The laterals will connect to this trunk and loop through the addition to connect to the ex- istifig 8" water main on Chapel Lane. A 12" diameter sanitary sewer trunk will extend southerly through the proposed ; addition from its present location at the east end of Chapel Lane. Lateral sanitary sewers draining to this trunk sewer will provide service throughout the Delaware Hills Addition. The 12" sanitary sewer trunk will also serve future development to the south of this addition. Page 1. Storm water from the proposed addition will drain into proposed storm sewer pond GP-1 which is now located in Bur Oak Park. The Master Plan for Storm Water Drainage provides that this pond be expanded which is shown on the pro- posed plat. The expanded pond lies in the natural low area of this proposed plat. Trunk and lateral storm sewers will drain all of the land in the addition into this pond. At some time in the future, a pumped discharge outlet for Pond GP-1 will be required. The excess water will be pumped to Pond EP-2 as shown on the Master Plan. EASEMENTS/RIGHTS-OF-WAY This plat should have at least a 10' wide drainage and utility easement on all front, side and rear lines of the plat. Twenty feet wide easements will be re- quired for sewer and water utilities crossing the plat and ponding easements are required for major Pond GP-1 and a small pond to be located near the east ; City Limits line. All streets rights-of-way are to be 60' wide and provision must be provided for a street connection to the south. Sanitary sewer, storm sewer and water main utilities serving the area south can be located in this proposed street. GRADING AND DRAINAGE 's... A detailed site grading and drainage plan has not yet been submitted. This will be required before final approval can be given. This plan must include consider- ation of the changes in grade to the various lots and an erosion control plan to minimize erosion during the development of this addition. The plan must also show the individual lot drainage patterns and the proposed house elevations for each lot. OTHER CONSIDERATIONS Because this plat outlets onto a trunk highway, it will be necessary to obtain approval from the Minnesota Department of Transportation for this proposed street access to Trunk Highway 49. A major pipe line easement containing three petroleum pipe lines passes through this plat and will require coordination with the Williams Bros. Pipeline Company during this development. Because this plat is immediately adjacent to the Inver Grove Heights boundary and because ownership by this developer extends into Inver Grove Heights with the proposed large lot subdivision in that City, it will be necessary to have close co- operation and agreements on layouts, utilities and streets with Inver Grove Heights for proper development. A future extension of Chapel Lane to connect into this plat was discussed during consideration of the previously approved preliminary plat. Renewed discussions on the timing of this street connection should be carried out with this proposed development. CONSIDERATIONS FOR APPROVAL The following comments should be considered in the final approval of the pro- posed plat: 1. Provide proper utility and drainage easements and connections to present trunk water, sanitary sewer and storm sewer systems. 2. Provide a detailed grading and drainage plan to be approved by the City Engineer prior to final plat approval.

Obtain approval from Minnesota Department of Transportation for the connection to Trunk Highway 49 and from the City of Inver Grove Heights and Dakota County for street connections through to County Road 63 east of the proposed plat. Provide a proper ~I erosion control plan in conjunction with site grading and drainage plan and provide effective erosion control during development. Mr. Colbert and I will be available to answer questions and provide further com- ments at the July 31 Planning Commission Meeting. Respectfully submitted, Robert W.
