1c. Resolution Authorizing Alternative Urban Areawide Review on Gateway PropertyCITY OF CHANHASSEN 690 COULTER DRIVE • P.O. BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937 -1900 • FAX (612) 937 -5739 MEMORANDUM TO: Don Ashworth, City Manager FROM: Kate Aanenson AICP, Planning Director DATE: March 19, 1997 SUBJ: Gateway request for an Alternative Environmental Assessment, Alternative Urban Area Wide Review (AUAR) BACKGROUND In March of 1994, the City Council approved allowing an Alternative Urban Area Review for the Environmental Assessment for the Gateway property. The development of the Gateway property never proceeded due to the Highway 5 Corridor Study. The developers even considered selling the property. The Developers met with the City Council in 1996 to discuss issues of concern regarding the development of the property including grading and an additional signal at Highway 5. At that council meeting, direction was given that the property should remain industrial and that the city should work proactively to accomplish this. This project is tentatively scheduled for conceptual review by the City Council on April 14, 1997. ANALYSIS The Gateway development includes 102.1 acres including 1,334,200 square feet of buildings. This level of development mandates an Environmental Impact Statement. The applicant is requesting that the Alternative Urban Area Wide Review (AUAR) be used. The AUAR is a hybrid of the EIS (Environmental Impact Statement) and an EAW (Environmental Assessment Worksheet). The AUAR does not eliminate any of the issues to be studied (traffic, noise, carbon monoxide, natural resources, water and wetlands, soils, stormwater runoff, etc.) it just shortens the time fame of the process. Attached are the items that will be studied in the AUAR and the Review Process. The city of Chanhassen will be the RGU (Responsible Governmental Unit). This means the city will hold the hearing, the review and hear comments on the assessment document. The Environmental Don Ashworth March 19, 1997 Page 2 Quality Board has approved using the AURA process. Because the City is the RGU, the City Council must adopt a resolution. RECOMMENDATION Staff is recommending that the City Council adopt a resolution recommending the AUAR be completed for the property known as the Gateway Development. Attachments 1. Resolution 2.

The applicant was required to wait until the Highway 5 Corridor Study was developed and prepare an Environmental Impact Statement (EIS) before additional approvals (preliminary) can be given. This project includes 178 acres and will include over 900,000 square feet of buildings. In the past months, the applicant has sought to revise their plan to incorporate the design issues recommended in the corridor study. The applicant has requested that staff review other options for an environmental assessment rather than an EIS. Staff is in concurrence that the requirement for an EIS, which is precipitated by the square footage of proposed buildings, is a lengthy process that would not provide any additional information that would be revealed through an Environmental Assessment Worksheet (EAW). ANALYSIS Paul Krauss and the applicant met with Greg Downing, from the Environmental Quality Board (EQB), and reviewed alternatives for an environmental assessment. Mr. Downing recommended an Alternative Urban Areawide Review (AUAR) process as a substitute for an environmental review. The AUAR is a hybrid of the EIS and EAW process. The process uses a standard list of questions like an EAW but provides a level of analysis for typical urban area impacts comparable to an EIS. Because the city has an approved comprehensive plan, we can use the AUAR process. Staff supports the AUAR process for the Gateway project. The boundaries of the project is limited to 184± acres of the Gateway development (Attachment #2). MEMORANDUM Don Ashworth March 9, 1994 Page 2 The city will act as the Responsible Government Unit (RGU). The applicant has completed a Phase I Environmental Audit. This will be a part of the AUAR document. The applicant is being asked to prepare the AUAR to address the issues as outlined in the EAW process (see Attachment #3). The city has contracted Strgar Roscoe Fausch, Inc. to complete the traffic element. All other issues in the assessment will be completed by the applicant. RECOMMENDATION Staff is recommending that the City Council adopt the a resolution recommending an Alternative Urban Areawide Review (AUAR) be completed for the property known as the Gateway development as identified on Attachment #2 with the issues addressed and identified in Attachment #3. .

Also be sure to consult the previous chapter for general information on the preparation of the facet 1 — ProjedMe The most important things about the tide for EAW purposes are that it indicate what kind of project is involved (e g. "residential subdivision." "gravel mine," "county toad resurfacing," etc.) and which one it is (eg, "Joe Smith gravel mire - Lbroln Township," "Ramsey County Road 17 Intpcovernents. —TH 1 to St. Paul City Limits"). 2 Wd 3 Self evlanatory. 4 — Reason for EAW PtEpwatbn This item refers to why the EAW was prepared. Most EAWs are prepared because of mandatory regtmemerits Cffffdatay EAW" statild be marled for these). If the EAW was not mandatory, malt either "citizen pel roar," "RGU discrt:ticn," a'pruPoser volunteezed" as appropriate to indicate how the EAW process was initiated. 'EIS suoping" should be uWad only if an M is mandatory or the proposer has voluntarily agreed to initiating an EIS. If the EAW or EIS is rrtarrdatcry, list the rule citation for the applicable rnardatory category(ies) from the EQB's Hiles. The citation can be found in eid= the Hiles themselves (at parts 4410.4300 or 4410.4400) or in the back of the Guide to the Rules. 5 — Project LOCdOn Township, range, and section numb= are found m deeds, US. Geological Survey 1 topographic maps, and county highway maps. The county assessor will also have this information. Maps end site plan Maps may be obtained firim wrap stores, the U.S. Geological Survey, and for county maps, the MN Dept. of Transportation (MrrD(M a the Canty in gtreWm (See Appendix B). Photocopies of maps are perfectly acceptable as long as they are dearly legible; if less than the complete map is copied, be store that the label of the map is included so reviewers can refer to the original map if necessary. Be sure to clearly madr the project boundaries on the map. The site plan should provide a graphic "dose -up" of the project in sufEciau detail m identify the key physcal cmtsnxxion features of the project This includes roads. ruler' ties. buildings, drainage strtrcttaes, an and fill areas, materials or waste storage areas, paricing Im and project boundaries. Significant natural features should also be indicated. Also note that some of the I= items on the EAW form ask that oerrain special features be noted on the site plan if they are present. 6 - Descripbon This is the single most important item in the EAW, and care should be taken to erutae that it is completed thoroughly and accurately. Additional sheets should be added to the EAW as needed to 10 provide a complete response. The description should be focused an aspects of the project that may directly or itdireedy manipulate, alma, or impact the physical enviomnenc This includes coasttuction methods, especially with respect ro site preparation; the opelaborW features; of due project, especially with respect to waste productim and management and in appropriate cases, (e.g., mining activities) project closure action. The EAW desciTtiori should not include mforn=cn which selves mainly to justify or "ptomio e" the project that sot of information is irrelevant to the EAW process. The purpose of the EAW is to identify and assess environmental impacrs. Abstract for use In MB M xft This should be a very ccociw statement of the basic name and _ characteristics of the project which the EQB staff can print verbatim it the EQB Monitor notice of the EAW. Do not exceed 50 wads. 7 — Ptojed Nkjklde Data This item asks for Certain data that trip quW* the magmnXb of the project, Depending on the type of project involved, some of the data regtrsrd may not be applicable, in which case simply leave the blank `blank" TOfal RqW Ara or Length For linear type projects such as roads, pipelines, sewers, elec= trarismission Imes the length should be given; for other projects the area should be given If the total acres involved in a linear project is ]mown, give both area and lengdn. ResidmW Unh9: Uattached / AttadW Single fhray, "duplex," and "triplex" emits are unattached units (rate that a duplex has two unattached units and a triplex has three) while anything with four or more units to a building has attached units and that each individual dwelling unit counts as one attached unit (e.g, a 24-unit apartment building has 24 attached units). Camnerdal / kxksM I hsewbiel Btrfkirtg Area The form now fits[ asks for a total of the gross floor space for any project of a comm=ial, industrial, or institutional ( school, prison, hospital) name. This counts all floors of all enclosed structures on the site except for any space used for parking. The form then asks for a breakdown of the total among nine subclasses of corium / ind / inst. space. This should be selfcxplanatc ry except for "agricultural" which is intended to include primarily the area of buildings for feedlot projects. If these is uncertainty about where something fits, list it under "other co merc:W7 and describe what it is. BttiJdrtg HeVft List at least the maximum height of the buildings; provide more inforriaricn where appropriate (e g., an office complex with two er mare towers of varying si= or an office tower with a comm unications tower mounted on tip). 8 — P21 nb and Approvals Reqund List the permits, approvals, reviews, and financing tequied from all governmental agencies prior to the commencement of the project ]include any necessary regional (e.g- Metropolitan C..D reviews and approvals. Include approvals already obtained A canpreherove fisting of state and local permits cc be obtained from the Munesom Small Business Assistance Offoe (listed in the appendix). The local unit's planning and zoning office can also help identify necessary MT'ks. The most likely federal permits to be required would be from the Army Caps of Engineers of the Fish and Wildlife 1 1 1 Service; their telephone numbers ate listed in Appendix A In responding to the various items on the worksheet if a potential environmental impact will or can be 11 addressed by conditions of any of the permits or approvals to be required of the project, this should be disctssed as pan of the respam to the item. This should be coordinated with the response to item 32, , Stmmery of Issues", which also provides an opportmity to explain how potential impacts can be mitigated ugh p provat conditions. it should be noted that when an EAW is required or ordered, no final decision to grant any governmental permit or approval (including financial assisance) can be made until either a decision has been made that no EIS is needed or until an EIS has been completed. (See pelt 44103100 or the Guide to the Rules) In some cases there may be permits previously issued for activities on or near the project site which are relevant to the review of the proposed project. This is most blcely where the proposed project is an expansion of an adsting project, but could occur under other corduris as well (e.g., where a past dredging project permitted by the Caps of Engineers or the DNR placed spoil on the site of the proposed project). These permits should be identified, inchding the permit number ad issuing agency. This irnfamatim can either be presented under this item or'(preferably) rider the hern(s) moo relevant to the nature of the permit 9 - Urtd 11513 The poh of this Westim is twofold: (1) to identify any pest land uses on the site which might cont to pre= environmental concerns (erg., soil contamination from pest industrial use); and (2) to ideruily arry potential conflicts between the project and ousting sin riding land uses which have arvaonmental aspects that may tagrme mitigation. A dam example would be a gravel operation proposed next to a residential area — dust and noise could Cau9e significant cori icts with the residential land use. The form asks whether potential land use conflicts involve environmental mattes because not all land use conflicts do —e.g., heavy truck traffic from a gravel mine near a residential area may cause a land use conflict due to safety cartms but this is not an environmental matter . The EQB tiles define "emQo mere to include: lard, air, water, minerals, flora, fauna, ambient now, energy resources, and mat -made objects or natural features of historic, geologic, or aesthetic significance (4410.0200, mbp. 23). 10 - COV2rTyp2S Estimates of the acres of land cover before and after the project is to be provided. One important purpose of this infm natim to to allow acsessri= of the impact of the project on wildlife habitat- Site surveys or recant aerial photos provide the best souroe of infomnawn.

The - wooded / fame category should be applied only to relatively radisaabed wooded areas; 'trban / suburGarm lawn / landscapamg" is the appropriate classification for developments constructed in wooded areas even if many of the tees ate maintained. Similarly, the ' hush / grassland" categories applies to areas that are radist rbed or infrequeimty maintained; if an area is to be regularly mowed or maintained, even if in a nral setting, list it under 'V= / suburban lawn / landscaping." 11 — FrA WHdk acid Eu�Wy &rdW Resources a Fish and wildlife habitat areas exist tuoughout the state and we not all specifically designated. State 111111 and federally designated refuges and protected trout streams or spawning areas are well- defined and lists can be obtained for your county. 1 ^ L Nearly all undeveloped land has some wildlife habitat value. The quality and value of the habitat depends on many factors including the degree of 6,arrbanoe the name of the adjoining areas, and the area and type of vegetation or water rsauces present Questions about the value of the habitat should be directed to the Regional Office of the DNR (see Appendix A). Keep in mind, however, that it is due responsibility of the RGU t deuermine the nature and sigt0carm of any project - related impacts. b "Ecologically sensitive tesarme generally refers to rate or urnique natural feaares or feaares of special sgn&canm Examples include threatened and endangered species habitats dm ate tale statewide (Ric}h as Prairie remna or vn m timber} botany tare habitats colonial watewd. nesting colonies and hi qua wedand complexes.

In assessing impacts on fish and wildlife resources, consider the Presence of oo1onial waterbard nesting colonies; nests of bald eagles, osprey, or loons; amportant waterfowl feeding or brooding areas; and odrr resources sensitive to disauberre. If applicable, discuss any mitigation measures which will be used to minimize conflicts, such as controls on watercraft and their sizes, motors and sizes, speed limits, and area zanmg. 16 — SOBS Describe the types of soils preset using the Sort Conservation Service (SCS) classification. Soil surveys showing this information are available from the County Agricultural Extension Office, the Sad and Water Canservation District office, or the S.C.S. District Field Office. If several sod types exist on the site, a soils map is helpful. It is not necessary to attach copies of the SCS sons kmpcetatiat (descriptim) sheets to the EAW. If soil borings have been made, it is sometimes important to attach a copy of the boring logs to the EAW. However, do is not necessary for marry projects It is important to attach the logs whenever the r .ojeex may have potential to contaminate the soils or ground water (including projects involving use of on-= sewage ueatrnerrt by septic tanks and drain fields). Where it is not apparent that the logs need to be attached, but 111111 borings have been made, you may simply note that the logs exist and are available upon request. 14 :.• • toft-0 v . ..• •• i • �•: •• -i •r •. •• i v �— , •:rw •:• •. u u: • u: Steep slopes (12% or more) and wasiom prone soils (as indicated by the information in item 11) should be described and shown on the site plan or on a separate grading plan.

E g.. if the project will only cause a small increase in impCMOUS surface and would add only minor amounts of any potential pollutants, it would be sufficient to qualitatively describe the extent of unease and give a general id=fimm of the types of pollutants involved (eg., f Ww / herbicides from suburban lawns: pollutants typical of park mg lot runoff) On the oiler hand if significant increase in nmoff will result and/or significant amounts or kinds of pollutants would result, a more detailed and quantitative assessment will be nary to adegMly characterize the impacts Similarly, the amount of detail provided about management / treatment methods should befit the significance of the quantities and quality of the ntraf. . Where it is clear or suspected that the runoff would pose weer quality problems if not adequately managed or arced. sufficient detail of the management / treatrnent system is needed so that reviewers can judge the adequacy of the proposed systm i ocaaons, dimensions, and design capacities of detention / retention basins should be given if such basi will be used to manage nuaff. Tlx EAW should discuss the conformance of the proposed system with any applicable requirements of the local municipality and any watershed district with prisdicaon over the area b The fast part of this answer should identify the point(s) of discharge of to stcrmwater system into recemg waters and also indicate any downstream receiving waters which may be influenoed by the stomtwater discharge, in tams of volumes or quality. Ibis is especially important where a downstream water is more sensitive or more valuable than the waters receiving the direct discharge. An estimate of the impact of the sormwater on the quality of the receiving wares should be made. The 111111 level of sophistication of this analysis mast be guided by the likely magnitude of the impact and the importance of the water body (ies) to be affected. Where it is clear on the bass of the ameunts and 15 quality of the stormwater compared to the volume, quality, and assimilative capacity of the receiving waters that only a minor degradaurn of water quatrty will occ and no noticeable imp pent of uses of the water would result, only a general gmlitadve disatssnah is heeded However, where noticeable impairment may oocra, toe qmmm assessnent methods should be employed ton the impacts, and predictions should be [trade about whether any water quality standards win be violated. it is now the policy of the EQB staff that where soormwater discharges may degrade certain high valoGhigh priority ]aloes, a numeri nutrient budges analysis should be performed to ado br char'ac== the extent of the potential impact The lakes for which this analysis is considered necessary ate identified in the appendix, part H The analysis should be based on a generally - accepted model of a lake's response to increase in phosphorus loading (or other critical nutrient if phosphon>,s is not limiting).

For normal domestic sewage generation, only the amounts need be given, calculated from the number of occupants, at a ran of 100 galbns/p=M/daY Unless aodrer figure is Jusdf� in the Particular case. For industrial processes, the sources of a ll wastewater saearns should be identified and a desaripoon should be given of how the various pomntW polhrtaus enter the stream or are generated within the stream. The anticipated chemical analysis of the various waste streams should be estimated, and the basis P for the estimate should be indicated (e&, measurements made at existing similar plant, etc.). For projects which themselves are wastewater t faaIuM the question should be answered with res p e ct m the wastewaters to be treated at the facility. _ For projects involving landfills or other lad disposal of wastes, leachates produced should be considered as wastewaters and identified hems b The most important point of this response is tD provide sig lent information about the nature of any proposed wastewater treatment system to demonstrate that the proposed system will be adequate to seat due wastewaters g nwared. The level of detail needed to do this will depend on the mane of the wastewaters and the proposed systern and the degree of t that must be achieved; where the wastewaters or proposed treatrnent medrods are non-routine, a higher level of detail drat due system will PCA P woad will be may. Fa' industrial wastewaters, It Is very advisable to consult with the staff 111111 regarding one infamaudn to be provided early in one EAW prepazatim prod.

Poss<blo sourm of information include: site surveys, son? surveys, topographic maps, the county sanitarian or health deprrmrerht, the State Departernt of Health, and the Murresora Geological Survey. If any such features are present at the site, the EAW should address how potential ground water contamination problems which could result from these hazards will be prevented C In response to this question the EAW should list any chemicals or other substances that well be on due site, for any purpose, which would be ground water contam umts if they entered the ground water, and identify how these materials well be prevented Jim entering the ground water The level of detail provided should be commensurate with the Molihood that the materials could enter the ground water, tte risk associated with the materials, and the quantities present or used. The response may reference other items as appropriate (erg., item 21 for storage tanks). a AII types of wastes generated by the pr41ect which are not wastewaters or air emissions should be identified hem This includes any hazardous wastes, all forms of what is normally termed ''solid wastes,- any sludges, any ashes from combustion, animal manures, demolition wastes, construction wastes, and asbestos. Estimates of due composition and quantities should be given. For common types of wastes of fairly unifemn composition, such as municipal solid waste and animal marrms, the composition reed not be identified other than as by type of waste (eg., "turkey manure mixed with straw bedding" would be Suffident). Far other types of wastes, especially is they are hazardous or mntauh toxic carstimeNs, a chemical analysis should be given (along with how it was determined). •'.I 1• Ii • "1✓1 • 1v, 1 1•••�� /1.1.1 1 •%1• 1• �iY. .1•�1Y.1' b This question is straightforward.

The trip generation rates used w estimate traffic (such as trips per houvrldd) and their source should be idardfied It is recommended that the Institute of T.a.., Engineers Trio Generation Manual infonnadom be used, unless other numbers are justified for the 1tirmular 1ro.1ecL The level of effort put into the analysis of the routing of the traffic generated on roadways and the resulting impact on congestion should be comrner>SUratC to de amount of traffic generated and the existing level of cangestim — i.e., the more lildy the project well coriaRM to a problem and the greater the problem, de mare detail that should be provded. The analysis should consida not only the adjoining roads but also other connecting roads that may be adversely impacted. One commonly measure of congestion that is appropriate to use in an EAW is the levelof- service and delay tunes. MM If a traffic analysis is being prepared because of the regiiir s of the local unit of government, that analysis should also be used for the EAW, provided drat it is based on generally - accepted principles of traffic analysis. 18 rect If a PCA indi source permit (ISp) is required (see item 23), the traffic analysis method used in the EAW f orm con struction area dust f rom demo ct tie dus g ene r ated I t on 1 p :/ roads o Fjj AI ' arM or dust f =W p l ocations F and ds 1 sensit w 1 / be given Pr oposed trutigat LO I w V 1 1 be described d i denti fy an stron or potentia 11 i V odcrs and i dent ify l ocations or and ist Y:w H V I receptors.

On the other hand, if item 12 indicates that the project may cause or worsen traffic congestion, an estimate of the air quality impact of this crngesrion must be presented ere. This analysis should fans primanny on carbon monoxide concentrations. Tine level of sophistication of this as quality analysis will depend on two factors Fast, the likely mag<ninrde of the air quality impact the grunter the anticipated impact, the more soptusticated and detailed the analysis must be Second, whether or not the project will require an ir>direct souaco permit (lisp) from the PCA. If the project requires an ISP, in most cases, the air quality analysis provided in the EAW should be the same analysis which will be required to apply for the isp the PCA should be oasvled before this analysis is Prepared Appendix F presents the PCA ISP nk Projects involving 500 or more padmg spaces may require an ISP, depending on odrr factors described in the rule. For assistance in interpreting the ISP Wile, contact the PCA. Some project which do not require an ISP may neventteless req = an estimate of likely air quality impacts if they may contribute to traffic oongestion. The most common example of this is where a project will attact large numbers of people but w ill rely on off -site paddng to aocommodate most of them The air quality analysis in such cases should be comparable to that used in the ISP process 24 — Stationary SUM A' EltussioM This response should identify any wares of air emissions other than traffic, fugitive dust wares, and odor sounxs. The most canmm souses of such emissions are boilers and mdi=ial processes. If there will be such emissicm this response should provide the infamadcn stated in the question The level of detail and the degree of soptnistication of the analysis should be cormnetwate with the magrnintde of the emiswrts and their blxly impacts on air quality. Where the emissions will be large and contain significant air ponutarts, gtan>tirative estimates derived from genenany-aocepted air quality models may be necessary . If the emissions will be minor only a qualiiauve description may be necessary. Air emission snares frequently tequtire air quality permits from the PCA and applicawns for such permits may regL= extensive information. In these cases, the EAW may be based on information developed far the air permit application. The propose is advised to convilt with the PCA regarding air permit rerlu irmierts prior to prepping the EAW data. 25 — Dust, Ochs, Noise Dust This includes "fugitive dusC which is defined as particulate mater uncontaminated with industrial emissions d= becomes airbome due either to the force of wind or man's activity (e.g., wind blown dust 111111 M vuth Plans The first question of this item is whether the project is subject to any 2$ — Compa�bt�ly official nuanagerruerrt plats for the area These could include a local .. �. �.a+e plan .�._.. til a use plan (w may =mm in any city in the Twm Cues metro area and possible elxwh=e a 1oca1 water Pte: or nmmgmm plats specific to special resauce areas under public rnanagernent (e.g, a pads plan watershed district plan, rive plan etc-)' Plats of all levels of goveaunent should be cortademd Mie-- local, regional, state, and federal. The local planning and zoning ice is probably the best source of this kind of atfcm>ation. If no such plaits exist in the area, the EAW should so indicate. If there is a plan of some soa, but the Project is not subject to the plan for some teason the EAW gKxdd indicate why the project is not subject to the plan- if there is a plan to which the project is subject, the EAW should identify the plan and its requuenems teleran[ to the project and should discuss how the project complies with the plan.

According to the EQB's rules, all "connected arbors" are to be reviewed as one project: "connected actions" are defined to be any projects related in any of the three following ways (1) one project would induce the other, (2) one project is a prerequisite for at ot =,, or (3) retier Project is justified by itself (pact 4410.0200, subp. 9b). Futther guidance regatdutg connecte is presented on Pages 7 and 9 of the doaunent Guide to the Rules,.

One of the criteria to be considered in detesminutg the reed for an EIS is the "cumulative potential effects of related or anticipated fuwae projects" ( 4410. 1700, subp. 7, item B). If the answer o a, b, a c is "yes," respond as indicated in the space following d, and also respond to subitem d. Take rote that if the answer to a. b, or c is "yes'• it may be that the project is related to other developments as a "phased action" or a "connected action" as defined by the EQB rules at part 4410.0200, subp. 60 and 9b, respectively. if phased or connected actions are involved, the EQB rules require that all parts " the actions be reviewed as a single project. Therefore, ¢ a, b, or c are answered "yes," the RGU is cautioned to refer to the EQB rules or the "Guide to the Rules" regarding the treaanent of phased actions and connected actions to ensure that the complete project has been reviewed in the EAW. In the rules, the relevant pmts are IIIIII 21 4410.]007, subp. 4 and 44102000, subp. 4 at weff as the definitions died above.
