PRESENT: Chairman Joe Plocher Mayor Valerie Burd Eric Dhuse (Public Works Director) Alderman George Gilson Joe Wywrot (City Engineer) Brendan McLaughlin (City Administrator) Alderman Marty Munns Alderman Diane Teeling Anne Engelhardt (C.O.Y. Green Committee Member) Marta Keane (C/O.Y. Green Committee Member) PRESENTATIONS : NONE The meeting was called to order @ 6 : 30 p.m. by Chairman Joe Plocher MINUTES FOR CORRECTION/APPROVAL: The minutes for June 16, 2009 and July 20, 2009 were reviewed and approved as presented. Items Recommended for Consent Agenda : 1. PW 2009-74 Tower Lane Water Storage Tank Rehab — Change Order # 1 2. PW 2009-75 Prairie Garden Subdivision — Final acceptance 3. PW 2009-76 Bristol Bay Unit 7 — Final Acceptance & Bond Adjustments 4. PW 2009-77 Goodwill Store — LOC Expiration 5. PW 2009-78 Fox Road LAPP Project — Change Order # 3 6.

PW 2009-81 Grande Reserve — Call LOC for Reimbursement for Cost of Consultant Services All items will move forward to Consent Agenda. NEW BUSINESS : 1. PW 2009-82 Water Conservation Enhancements to landscape Ordinance Marta Keane & Anne Engelhardt want a requirement that a landscaping tree be planted on the side of a lot during development. This could add value to a home and save on heating and cooling costs. It was agreed upon to amend the existing ordinance to require a tree to be added on the lot of single family & duplex during development. Move forward to Consent Agenda. 1 2. PW 2009-83 Country Hills Subdivision — Final Acceptance & Warranty Bonding Joe Wywrot said the developer and Prairie Garden have verbally requested to waive the warranty bond amount. Joe is not recommending that we eliminate the warranty bond amount, but perhaps consider reducing it. Based on the estimates of costs of three sets of plans the warranty bond amount would be roughly $212K. If you had a warranty bond amount just for unit 2, the bond amount would be $ 111K. He recommends that we stay at the full amount of $212K. Chairman Joe Plocher agrees as well to the full amount. Alderman Gilson asked when does expect the drawings to complete. Joe said 3 to 4 months for final documents. Alderman Gilson asked would the $212K warranty bond cover warranty costs at today' s prices. Joe said yes. Alderman Gilson agreed to keep the warranty bond the same. Item move to Consent Agenda. — The Country Hills developer Dennis Dwyer entered the meeting approximately @ 7: 10 and was informed the city required the full amount of the bond. He doesn't agree with the decision. 3. PW 2009-84 River Road Bridge — Update Joe Wywrot said this bridge is in poor condition. He also said he submitted IDOT Major Bridge Program Grant Application yesterday. He believes we should find out by the end of the year to see if we make the cut or not. The fact that the bridge has been downgraded to poor condition can help us in getting grant money. The estimated cost of replacing this bridge is $3 Million dollars. If we get the grant from IDOT and the $200K from the county, our costs would be approximately $900K. Alderman Gilson had concerns about the costs to the city and the removal of the damn. Should we wait until we know the fate of the damn before we proceed? He suggests we wait for all of the input. Chairman Plocher said we start looking for funding options now. He also said it' s not a matter of if, it' s a matter of when. These pictures of the bridge were taken in 2004 and it is now 2009. Mayor Burd stated that this is a safety issue. We are responsible for the bridge. If the bridge is already being rated as poor and by the time they get around to giving us the grant and funding, we're talking several years will go by. Joe said it will be about six years before construction. The current grant cycle is for 2015 construction. Alderman Gilson asked it will be 6 years? He also asked if we're letting people cross the bridge. Joe said IDOT didn't feel posting it below legal load limits. He also said to steer overloads away from the bridge which we've been doing for years. Considered Informational Item. 2 4. PW 2009-85 Traffic Study — Church and W. Main Street Church yields to Main. Church has more traffic. Recommending switching the yield sign and having Main yield to Church. 5. PW 2009-86 Traffic Study — Kylyn's Ridge Two intersections — One in the Cannonball Estates Subdivision — Western & High Ridge and the other at the Kyln' s Ridge Intersection. We recommend leaving them as is. 6. PW 2009-87 Traffic Study — Van Emmon and Heustis Currently Van Emmon stops at Heustis. We recommend that switching that so that Heustis stops at Van Emmon. We talked to Chief Martin and he has no objection and we talked to the school district and they had no objection either. All will move to Public Safety and let them know we recommended for Consent Agenda. 7. PW 2009-88 Policy Regarding SSA's and Security Bonding/Letters of Credit Alderman Gilson is recommending to develop a policy accounting for the costs of inflation overtime with bonds and when we review we can reduce bonds. We review the bonds annually from date of issuance regardless of status. The costs for us to cover any thing that may happen and if the developer would go bankrupt, that would cover that. We would be secure in the fact that we would have the money in place for any added costs overtime. Bring back next month with a written up Policy. 8. PW 2009-89 Heartland Circle — Discussion of Weeds & Dumping Issues — Update Informational Item OLD BUSINESS : 1. PW 2009-63 Fly Dumping in Vacant Areas of Subdivisions Eric Dhuse said it is a problem in every subdivision. Neighbors have to watch and take down the license plate of violators. 2. PW 2009-73 Stormwater Basin Maintenance Joe Wywrot giving ourselves the power to see that stormwater basins are maintained properly. Kathy Orr & Joe believe that the easement language gives us the ability to rush in and save the day if there' s a problem. But if we do that, it will cost us money and how do we collect and get reimbursed. Kathy feels an ordinance would be appropriate and to enforce that ordinance through the administrative adjudication process. With the committees' permission, go back to Kathy to create an ordinance and get it on the City Council Agenda soon. 3. PW 2009-68 Water Meter Pricing Alderman Gilson still questioning the pricing and looking for justification, but Eric said the developer said this is the costs of the technology. After much more discussion on this item will move to Consent Agenda. Alderman Gilson objects from this moving forward until a cost justification is provided. 3 4. PW 2008-111 Material Storage Shed Replacement Update Eric Dhuse informed everyone of funding in the capital budget of $40K for building a replacement of Material Storage Shed. Already met with one contractor and trying to meet with two other contractors to get some ideas of pricing. He would like to have everything done with the bidding out or in the process of bidding out by the time everything goes through otherwise we will have to wait until the spring.

This property was developed in 2004 and the site plan called for the sidewalk along Route 47 to be constructed in an easement adjacent to the right-of-way. The sidewalk was constructed in the correct location, but the easement was not dedicated at that time. IDOT has recently increased their effort in pursuing easements for their Route 47 widening project. They called us to see if a sidewalk easement existed in this area, and that's when we checked our files and found that the easement had not been dedicated. 1DOT asked us to modify the originally proposed easement dimensions by adding a small area just south of Landmark, thereby eliminating the need for them to obtain an easement for that area. The attached easement includes that small additional area. 1 recommend that this easement document be approved and recorded. Please place this item on the September 15, 2009 Public Works Committee agenda for consideration.

As per article 550.04, when rock or in this case concrete is found near the excavation, it shall be removed to a minimum of 8" below the bottom of the pipe. The concrete was broken and hauled away and replaced with additional aggregate to get to the proper bedding grade. The pipe also was required to be lowered to ensure proper clearance between the phone and gas lines near the south end of the culvert and water and sewer force main on the north end of the culvert, since the existing pipe was corrugated metal and the proposed pipe is reinforced concrete and has thicker walls. This additional work will be paid on a force account basis, according to Article 109.04. The requested amount is from the final bill which has been checked and verified.

A water conservation seminar was held in April of 2008, and most recently water conservation was one of the educational topics at the Environmental Fair in March 2009. Upon the heels of the Water Conservation Seminar, a water conservation plan was drafted by the committee in April 2008 and brought before the Public Works Committee on July 15 , 2008. This plan had two components: education and implementation efforts. Following the July 2008 Public Works meeting, staff prepared an informational memo outlining the efforts already being done and providing feedback on the suggested implementation efforts. Upon hearing these comments.. the committee still felt that changes were necessary to City ordinances and planned to continue their education efforts on the topic (as witnessed by the Environmental Fair). Former Alderman Bob Allen and staff, advised the committee to provide specific text amendments to City Ordinances as opposed to a general outline on how to conserve water in order to best achieve their goal. The text amendment to the Park Development Standards originally called for the removal of Paragraph F-2 in Section 4. Park and Recreation staff reviewed the request and recommended a reduction in the sodded area from 100 feet (which is the entire entrance width) to 50 feet maximum of sodding if the park entrance is less than 100 feet in width. The reduction of sodding in width instead of removal of the entire paragraph is due to the high traffic by bike and foot at these park entrances. Not using sod can also result in other forms of water use, for example, the foot traffic can cause mud to be tracked all over the concrete, resulting in the need to power wash the concrete to remove it. Also, if seed is used at the wrong time of the year and it doesn't establish, rain can erode the seed and soil, causing pollution and sedimentation. Sodding helps to prevent these issues. The text amendment has been amended to show a 50 ft. maximum of sod use at any park entrance 100 feet in width or less, which was agreed to by the Yorkville Green Committee at their meeting in June.

Or as defined by the US Army Corp of Engineers (USACE). N . AASHTO : Whenever reference is made to the AASHTO it shall be understood to mean the "Guide for the development of bicycle facilities" and subsequent documents referencing pedestrian or bicycle facilities published by the American Association of State Highway and Transportation Officials. 0. CMAP : Chicago Metropolitan Agency for Planning, formerly titled the Northeastern Illinois Planning Commission (NIPC). - 5 - SECTION 2: OPEN SPACE SYSTEM AND GUIDELINES The Chicago Metropolitan Agency for Planning (CMAP) states that: "Open space provides more than recreational opportunities; it is land that society needs to conserve as natural, cultural, historic, and agricultural resources. One of the most common misconceptions regarding open space and recreation is that the two terms are synonymous. A strong relationship does exist between open space and outdoor recreation but, in most cases, recreation is something separate and distinct from open space." Therefore, a park is open space, but open space is not necessarily a park. A . CATEGORIES OF OPEN SPACE The National Recreation and Park Association (NRPA) has developed six (6) categories of open space that the United City of Yorkville has simplified into three recognized categories of land capacity : environmental, shaping, and recreational. The United City of Yorkville has determined that acquisition and development of land meeting the recreational and environmental requirements of its residents is its role in the fabric of the community. These functions are subdivided into both local and regional classifications. The Parks Department's responsibilities pertain to the local classifications. 1 . ENVIRONMENTAL CAPACITY - protects natural and or cultural resources from development. a. Natural Resource Park (Linear Greenway/Trail System) - is utilized as a buffer zone, watershed, or conservation area, and affords a passive appearance with managed natural habitats and plant ecosystems. These areas can be used to protect fragile or rare ecosystems. Often these areas require management to maintain sustainability and preserve healthy biodiversity of plant life. When utilized as a linear greenbelt and/or trail corridor, natural areas can serve as environmental bridges, supporting the movement of wildlife between other larger areas. When combined with public use areas, development can include open play areas, pedestrian and bicycle paths, park benches, picnic and rest areas, and water oriented facilities. Detention or retention ponds can be included in these areas. In instances where this classification of park is flood prone, construction of permanent structures is discouraged. The public use infrastructure should remain supplementary to the functional classification of lands described. b. Conservation of local resources, such as streams, wetland habitats, and forests. c. Preservation of environmental and/or historic resources in conjunction with local historic preservation agencies. - 6 - 2. SHAPING CAPACITY - provides relief from extensive urbanization and promotes the integration of neighborhoods. City, county, state, and federal planning agencies commonly define this land as `land that shapes a community and is reflected in greenbelts, county forest preserves, state, and national parks." This category is also reflected in local ordinances stipulating density formulas and open space requirements for subdivisions. 3 . RECREATIONAL CAPACITY - provides space for single or multiple, active and passive recreation activities. a. Mini-Parks — The mini-park is used to serve isolated or limited recreational needs. Mini-parks are often tot lots, created to serve a resident population too distant from a community park, or in an area with high density populations. The mini-park is larger than one (l ) acre in size. Development is usually limited, requiring no parking or extensive site work. b. Neighborhood Parks — The neighborhood park is intended as a supplement to or substitute for a play lot where population density, geographic barriers or distance preclude easy access. Examples of such facilities include: play apparatus areas for pre-school and elementary children; hard surface areas for hopscotch, shuffleboard, tetherball, four-square; court games for basketball, volleyball, badminton, tennis, etc.; and open play areas for softball, football, soccer, and winter sports. The minimum park size for a neighborhood park is five (5) acres. The concept of development emphasizes spontaneous rather than higher organized play. The playground should be easily accessible to pedestrian use. Neighborhood parks can have additional special use classifications to include activities such as active play and specialized courts. These parks may be combined with school sites. Although any classification of park can be located next to a school , the age of users makes it preferable that neighborhood parks and elementary schools share a common boundary . c. Community Parks - The community park is larger than ten (10) acres, and development is intended for people of all ages. It is preferred that the park be centrally located and serve at least four neighborhoods. Amenities found in a neighborhood park shall be included, supplemented by large multipurpose open spaces. Internal walk patterns for pedestrians and bicycle paths are desired to connect the various functions. It should be accessible by motorized and non-motorized traffic. Adequate off-street parking shall be provided in accordance with amenities constructed. The classification may also serve as a neighborhood park facility for the area in which it is located . 1 .

The - 7 - location and design shall satisfy one or more of the following requirements : ( 1 ) avoid duplication of land and facilities unless existing facilities are over utilized : (2) coordination of services, and (3) diminish capital expenditures and satisfy the needs of each agency. Development should be similar to the neighborhood park. 2. Sports Complex - Developed to meet the needs of specific users groups and local athletic associations for practice, team, and tournament play. These sites have adequate parking and are located on good traffic routes. They may also be located to take advantage of bicycle and pedestrian trail systems. Fields should be as multipurpose as possible, so a wide variety of flexibility can be maintained. It is best to allow for additional space when acquiring sports complex space, as needs and trends are subject to constant change. 3 . Special Use Parks - Intended for single interest activities and large enough to accommodate the demand. Examples include: tennis center, outdoor education center, museum, conservatory, golf course, children's farm, sports complex, skate park, splash / spray park, swimming pool / aquatic center, etc. Since users are going to come from a distance, the site should be near major vehicular access routes and regional bike trails. d. Regional Parks — The regional park attracts people from outside the community. Regional parks shall be a large piece of property, greater than folly (40) acres in size with more than one major attraction or function . The regional park can encompass any neighborhood and community classifications. B. LAND / CASH DEDICATION ORDINANCES I . The United City of Yorkville Land Cash Ordinance requires ten (10) acres per 1 ,000 population be donated for parks as part of the subdivision or planned unit development approval process. The contribution of land cash is in accordance with the City Land Cash Ordinance. It is for these stipulated acres that the following standards have been developed . These standards will also act as guidelines for land donated to satisfy other functions of open space. The ultimate population density to be generated by a subdivision or planned unit development shall bear directly on the amount of land required to be dedicated for park and recreation sites. The acreage of land dedication requirement shall be determined by obtaining the total population of the development times ten (10) acres per 1 ,000 population. Total population is determined by applying the estimated ultimate population per dwelling unit table to the number of respective units in the development. Each single family home will be calculated to have four bedrooms; Duplex unit will be calculated as 50% two bedroom units and 50% - 8 - three bedroom units; Town home and apartments will be calculated with two bedrooms. 2. if the city determines that available land is inappropriate for park, or recreational use, the City shall require a cash contribution. This is based on the land cash calculation and the value per acre of the land based on the "Fair market value". The amount of land cash distribution shall be determined by Staff and Board analysis of the site and relationship to neighboring parks. 3 . In cases approved by the Park and Recreation Board, the contribution of land cash can be a mixture of 50% land 50% cash, or other agreed upon contribution combination. 4. A developer may donate the land together with cash for park development upfront to have the construction of the park expedited. Front funding for park development is preferred. Otherwise, a 75% build-out standard for the subdivision shall be set in place for park development. 5 . No land cash credit shall be given for the following: a. Exclusively private facilities & parks. b. Retention or detention areas, measured at the top of the bank. c. Lands located within the 100 year floodplain. 6. Full or partial credit will be given for the following: a. Active wet areas (lakes, rivers, creeks), historical areas, conservation areas, etc., that are identified to have recreational or conservation value. This will be considered on a case-by-case basis. Studies shall be required to verify historical and/or conservation areas. b. Paths or trails constructed and dedicated in an exclusive easement to the City, or paths identified as infrastructure or connecting trails to a regional trail system . Partial credit may be given for undeveloped exclusive easements dedicated to the City for future trail development. c. Land donations that are usable and/or classified as developable for use by the general public. - 9 - SECTION 3: PARK DEVELOPMENT TIMELINE AND PROCEDURES A .

O. CMAP: Chicago Metropolitan Agency for Planning, formerly titled the Northeastern Illinois Planning Commission (NIPC). - 5 - SECTION 2: OPEN SPACE SYSTEM AND GUIDELINES The Chicago Metropolitan Agency for Planning (CMAP) states that: "Open space provides more than recreational opportunities; it is land that society needs to conserve as natural, cultural, historic, and agrieultm a] resources. One of the most common misconceptions regarding open space and recreation is that the two terms are synonymous. A strong relationship does exist between open space and outdoor recreation but, in most cases, recreation is something separate and distinct from open space." Therefore, a park is open space, but open space is not necessarily a park. A. CATEGORIES OF OPEN SPACE The National Recreation and Park Association (NRPA) has developed six (6) categories of open space that the United City of Yorkville has simplified into three recognized categories of land capacity: environmental, shaping, and recreational. The United City of Yorkville has determined that acquisition and development of land meeting the recreational and environmental requirements of its residents is its role in the fabric of the community. These functions are subdivided into both local and regional classifications. The Parks Department's responsibilities pertain to the local classifications. 1 . ENVIRONMENTAL CAPACITY - protects natural and m cultural resources from development. a. Natural Resource Pink (Linear Greenway/Trail System) - is utilized as a buffer zone, watershed, or conservation area, and affords a passive appearance with managed natural habitats and plant ecosystems. These areas can be used to protect fragile m rare ecosystems. Often these areas require management to maintain sustainability and preserve healthy biodiversity of plant life. When utilized as a linear greenbelt and/or trail corridor, natural areas can serve as environmental bridges, supporting the movement of wildlife between other larger areas. When combined with public use areas, development can include open play areas, pedestrian and bicycle paths, park benches, picnic and rest areas, and water oriented facilities. Detention or retention ponds can be included in these areas. In instances where this classification of park is flood prone, construction of permanent structures is discouraged. The public use infrastructure should remain supplementary to the functional classification of lands described. b. Conservation of local resources, such as streams, wetland habitats, and forests. c. Preservation of environmental and/or historic resources in conjunction with local historic preservation agencies. - 6 - 2. SHAPING CAPACITY - provides relief from extensive urbanization and promotes the integration of neighborhoods. City, county, state, and federal planning agencies commonly define this land as "land that shapes a community and is reflected in greenbelts, county forest preseves, state, and national parks." This category is also reflected in local ordinances stipulating density formulas and open space requirements for subdivisions. 3 . RECREATIONAL, CAPACITY - provides space for single or multiple, active and passive recreation activities. a. Mini-Parks — The mini-park is used to serve isolated or limited recreational needs. Mini-parks are often tot lots, created to serve a resident population too distant from a community park, or in an area with high density populations. The mini-park is larger than one (1 ) acre in size. Development is usually limited, requiring no parking or extensive site work. b. Neighborhood Parks — The neighborhood park is intended as a supplement to or substitute for a play lot where population density, geographic barriers or distance preclude easy access. Examples of such facilities include: play apparatus areas fm prc-school and elementary children; hard surface areas for hopscotch, shuffleboard, tetherball, four-square; court games for basketball, volleyball, badminton, tennis, etc.; and open play areas for softball, football, soccer, and winter sports. The minimum park size for a neighborhood park is five (5) acres. The concept of development emphasizes spontaneous rather than higher organized play. The playground should be easily accessible to pedestrian use. Neighborhood parks can have additional special use classifications to include activities such as active play and specialized courts. These parks may be combined with school sites. Although any classification of park can be located next to a school, the age of users makes it preferable that neighborhood parks and elementary schools share a common boundary. c. Community Parks - The community park is larger than ten (10) acres, and development is intended for people of all ages. It is preferred that the park be centrally located and serve at least four neighborhoods. Amenities found in a neighborhood park shall be included, supplemented by large multipurpose open spaces. Internal walk patterns for pedestrians and bicycle paths are desired to connect the various functions. It should be accessible by motorized and non-motorized traffic. Adequate off-street parking shall be provided in accordance with amenities constructed. The classification may also serve as a neighborhood park facility for the area in which it is located. 1 . Athletic Parks — Multiple athletic fields in one location, representing the functional needs of each agency, which can be located in close proximity to schools where the public and students can share facility use. The - 7 - location and design shall satisfy one or more of the following requirements: ( I ) avoid duplication of land and facilities unless existing facilities are over utilized: (2) coordination of services, and (3) diminish capital expenditures and satisfy the needs of each agency. Development should be similar to the neighborhood park. 2. Sports Complex - Developed to meet the needs of specific users groups and local athletic associations for practice, team, and tournament play. These sites have adequate parking and are located on good traffic routes. They may also be located to take advantage of bicycle and pedestrian trail systems. Fields should be as multipurpose as possible, so a wide variety of flexibility can be maintained. It is best to allow for additional space when acquiring sports complex space, as needs and trends are subject to constant change. 3. Special Use Parks - Intended for single interest activities and large enough to accommodate the demand. Examples include: tennis center, outdoor education center, museum, conservatory, golf course, children's farm, sports complex, skate park, splash / spray park, swimming pool / aquatic center, etc. Since users are going to come from a distance, the site should be near major vehicular access routes and regional bike trails. d. Regional Parks — 'File regional park attracts people from outside the community. Regional parks shall be a large piece of property, greater than forty (40) acres in size with more than one major attraction or function. The regional park can encompass any neighborhood and community classifications. B. LAND / CASI-I DEDICATION ORDINANCES 1 , The United City of Yorkville Land Cash Ordinance requires ten ( 10) acres per 1 ,000 population be donated for parks as part of the subdivision or planted unit development approval process. The contribution of land cash is in accordance with the City Land Cash Ordinance. It is for these stipulated acres that the following standards have been developed. These standards will also act as guidelines for land donated to satisfy other functions of open space. The ultimate population density to be generated by a subdivision or planned unit development shall bear directly on the amount of land required to be dedicated for park and recreation sites. The acreage of land dedication requirement shall be determined by obtaining the total population of the development times ten ( 10) acres per 1 ,000 population. Total population is determined by applying the estimated ultimate population per dwelling unit table to the number of respective units in the development. Each single family home will be calculated to have four bedrooms; Duplex unit will be calculated as 50% two bedroom units and 50% - 8 - three bedroom units;Town home and apartments will be calculated with two bedrooms. 2. Jf the city determines that available land is inappropriate for park,or recreational Deleted:When use,the City shall require a cash contribution. This is based on the land cash calculation and the value per acre of the land based on the"Fair market value". The amount of land cash distribution shall be determined by Staff and Board analysis of the site and relationship to neighboring parks. 3. In cases approved by the Park and Recreation Board,the contribution of land cash can be a mixture of 50%land 50%cash,or other agreed upon contribution combination. 4. A developer may donate the land together with cash for park development upfront to have the construction of the park expedited. Front funding for park development is preferred.Otherwise,a 75%build-out standard for the subdivision shall be set in place for park development. 5. No land cash credit shall be given for the following: a. Exclusively private facilities&, parks. b. Retention or detention areas,measured at the top of the bank. c. Lands located within the 100 year floodplain. G. Full or partial credit will be given for the following: a. Active wet areas(lakes, rivers, creeks),historical areas,conservation areas, etc.,that are identified to have recreational or conservation value. This will be considered on a case-by-case basis. Studies shall be required to verify historical and/or conservation areas. b. Paths or trails constructed and dedicated in an exclusive easement to the City. or paths identified as infrastructure or connecting trails to a regional trail system. Partial credit may be given for undeveloped exclusive easements dedicated to the City for future trail development. Comment tLltl]:Ideally we watt them to be exclusive.We have the right to put utilities In our easement, c. Land donations that are usable and/or classified as developable for use by the but typically we don't want conflicts.I general public. don't want to not say excluswe so we don't get shared easements with other companies. -9- SECTION 3:PARK DEVELOPMENT TIMELINE AND PROCEDURES A.

Or as defined by the US Army Corp of Engineers (USAGE). N . AASHTO: Whenever reference is made to the AASHTO it shall be understood to mean the "Guide for the development of bicycle facilities" and subsequent documents referencing pedestrian or bicycle facilities published by the American Association of State Highway and Transportation Officials, O. CMAP: Chicago Metropolitan Agency for Planning, formerly titled the Northeastern Illinois Planning Commission (NIPC). 5 - SECTION 2: OPEN SPACE SYSTEM AND GUIDELINES The Chicago Metropolitan Agency for Planning (CMAP) states that: "Open space provides more than recreational opportunities; it is land that society needs to conserve as natural, cultural, historic, and agricultural resources. One of the most common misconceptions regarding open space and recreation is that the two let ms are synonymous. A strong relationship does exist between open space and outdoor recreation but, in most cases, recreation is something separate and distinct from open space." Therefore, a park is open space, but open space is not necessarily a park. A. CATEGORIES OF OPEN SPACE The National Recreation and Park Association (NRPA) has developed six (6) categories of open space that the United City of Yorkville has simplified into three recognized categories of land capacity: environmental, shaping, and recreational. The United City of Yorkville has determined that acquisition and development of land meeting the recreational and environmental requirements of its residents is its role in the fabric of the community. These functions are subdivided into both local and regional classifications. The Parks Department's responsibilities pertain to the local classifications. 1 . ENVIRONMENTAL CAPACITY - protects natural and orcultural resources from development. a. Natural Resource Park (Linear G'eenway/Trail System) - is utilized as a buffer zone, watershed, or conservation area, and affords a passive appearance with managed natural habitats and plant ecosystems. These areas can be used to protect fragile or rare ecosystems. Often these areas require management to maintain sustainability and preserve healthy biodiversity of plant life. When utilized as a linear greenbelt and/or trail corridor, natural areas can serve as environmental bridges, supporting the movement of wildlife between other larger areas. When combined with public use areas, development can include open play areas, pedestrian and bicycle paths, park benches, picnic and rest areas, and water oriented facilities. Detention or retention ponds can be included in these areas. In instances where this classification of park is flood prone, construction of permanent structures is discouraged. The public use infrastructure should remain supplementary to the functional classification of lands described. b. Conservation of local resources, such as streams, wetland habitats, and forests. c. Preservation of environmental and/or historic resources in conjunction with local historic preservation agencies. - 6 - 1 SHAPING CAPACITY - provides relief fiont extensive urbanization and promotes the integration of neighborhoods. City, county, state, and federal planning agencies commonly define this land as `land that shapes a community and is reflected in greenbelts, county forest preserves, state, and national parks." This category is also reflected in local ordinances stipulating density formulas and open space requirements for subdivisions. 3. RECREATIONAL CAPACITY - provides space for single or multiple, active and passive recreation activities. a. Mini-Parks — The mini-park is used to serve isolated or limited recreational needs. Mini-parks are often tot lots, created to serve a resident population too distant from a community park, or in an area with high density populations. The mini-park is larger than one (1 ) acre in size. Development is usually limited, requiring no parking or extensive site work. b. Neighborhood Parks — The neighborhood park is intended as a supplement to m substitute for a play lot where population density, geographic barriers or distance preclude easy access. Examples of such facilities include: play apparatus areas for pre-school and elementary children; hard surface areas for hopscotch, shuffleboard, tetherball, four-square; court games for basketball, volleyball, hadminton, tennis, etc.; and open play areas for softball, football, soccer, and winter sports. The minimum park size for a neighborhood park is five (S) acres. The concept of development emphasizes spontaneous rather than higher organized play. The playground should be easily accessible to pedestrian use. Neighborhood parks can have additional special use classifications to include activities such as active play and specialized touts. These parks may be combined with school sites. Although any classification of park can be located next to a school, the age of users makes it preferable that neighborhood parks and elementary schools share a common boundary. c. Community Parks - The community park is larger than ten ( 10) acres, and development is intended for people of all ages. It is preferred that the park be centrally located and serve at least four neighborhoods. Amenities found in a neighborhood park shall be included, supplemented by large multipurpose open spaces. internal walk patterns for pedestrians and bicycle paths are desired to connect the various functions. It should be accessible by motorized and non-motorized traffic. Adequate off-street parking shall be provided in accordance with amenities constructed. The classification may also serve as a neighborhood park facility for the area in which it is located. L Athletic Parks — Multiple athletic fields in one location, representing the functional needs of each agency, which can be located in close proximity to schools where the public and students can share facility use. The - 7 - location and design shall satisfy one or more of the to] lowing requirements: Q ) avoid duplication of land and facilities unless existing facilities are over utilized: (2) coordination of services, and (3) diminish capital expenditures and satisfy the needs of each agency. Development should be similar to the neighborhood park. 2. Sports Complex - Developed to meet the needs of specific users groups and local athletic associations for practice, team, and tournament play. These sites have adequate parking and are located on good traffic routes. They may also be located to take advantage of bicycle and pedestrian trail systems. Fields should be as multipurpose as possible, so a wide variety of flexibility can be maintained. It is best to allow for additional space when acquiring sports complex space, as needs and trends are subject to constant change. 3. Special Use Parks - Intended for single interest activities and large enough to accommodate the demand. Examples include: tennis center, outdoor education center, museum, conservatory, golf course, children's farm, sports complex, skate park, splash / spray park, swimming pool / aquatic center, etc. Since users are going to come from a distance, the site should be near major vehicular access routes and regional bike trails. d. Regional Parks — The regional park attracts people from outside the community. Regional parks shall be a large piece of property, greater than forty (40) acres in size with more than one major attraction or function. The regional park can encompass any neighborhood and community classifications. B. LAND / CASH DEDICA'T'ION ORDINANCES I . The United City of Yorkville Land Cash Ordinance requires ten (10) acres per 1 ,000 population be donated for parks as part of the subdivision or planned unit development approval process. The contribution of land cash is in accordance with the City Land Cash Ordinance. It is fm these stipulated acres that the following standards have been developed. These standards will also act as guidelines for land donated to satisfy other functions of open space. The ultimate population density to be generated by a subdivision or planned unit development shall bear directly on the amount of land required to be dedicated for park and recreation sites. The acreage of land dedication requirement shall be determined by obtaining the total population of the development times ten (10) acres per 1 ,000 population. Total population is determined by applying the estimated ultimate population per dwelling unit table to the number of respective whits in the development. Each single family home will be calculated to have four bedrooms; Duplex unit will be calculated as 50% two bedroom units and 50% - 8 - three bedroom units; Town home and apartments will be calculated with two bedrooms. 2. when available land is inappropriate for park, or recreational use, the City shall require a cash contribution.

Me morandum Ott esr. , : 1836 To: Public Works Committee From: Stephanie Boettcher, Senior Planne 0 CC: Bart Olson, Assistant City Administrator and Lisa Pickering, Deputy 09 '�0 Clerk (for distribution) � Date: July 15, 2009 Subject: Commercial and Multi Family Recycling The Yorkville Green Committee has discussed how the City could increase recycling throughout the City of Yorkville. Through this discussion providing recycling services to those not covered by the current Yorkville franchise agreement with Veolia, multi-family and commercial properties, surfaced as a viable solution. The Green Committee approved a recommendation, which is attached, requesting the City begin the franchise agreement process to provide recycling to commercial and multi-family properties. Recent legislation (Public Act 95-856) approved in October 2008, and is attached, requires the following steps in order to enter into a franchise agreement for non-residential properties. • At least one public hearing, in which all private entities providing non-residential waste collection have received 30 days written notice of said hearing in addition to the required public notice. • At said public hearing, the municipality must disclose the franchise fee or calculation formula for the fee • The municipality is not allowed to begin providing waste collection services until 15 months after the resolution/ordinance awarding the franchise is adopted. There are many examples of how municipalities provide trash and recycling collection to commercial and multi-family properties, which have been summarized below. 1 . City encouragement of businesses through education 2. Mandatory requirement, but non-residential properties are allowed to choose which hauler. Some municipalities require just 1 or 2 items to be recycled from each business. 3 . Franchise agreement. The Green Committee discussed each of three ways listed above and felt the benefits of a franchise agreement outweighed the benefits of the other two. Benefits of the franchise agreement are providing recycling services with garbage service at equitable prices and ensuring that recycling services are being offered at all businesses. There are also environmental benefits of fewer solid waste trucks on the streets, which can result in less damage to City streets, a relief in traffic congestion, less fuel and energy consumed, and less greenhouse gases emitted. A franchise agreement ensures that recycling is provided at all commercial properties, something encouragement alone cannot due. The franchise agreement also reduces the solid waste trucks and potentially the multitude of garbage dumpsters behind buildings (as multiple properties could share one), which would not be the case if properties are continued to allowed to choose their provider. Staff recommends, that upon approval to proceed, meetings are held with business owners and the Yorkville Chamber of Commerce to gauge interest. The Yorkville Chamber of Commerce recently started a green group, which could be a good avenue for discussion on this topic. These meetings or a survey developed by staff could also identify what companies are providing services, current rates for service, and assess how many businesses already have recycling services. Upon receiving this information, a franchise agreement can be pursued at that time. Ci p EST. 1 11336 Yorkville Green Committee Recommendation Form 0 ®i ` O < LE Title: Commercial Recycling & Exploration of Franchise Agreement Date of Recommendation: February 3 , 2009 Synopsis: The Yorkville Green Committee has been discussing the ways to improve recycling for residents, businesses, non-profits and schools for over a year. The Committee believes that the commercial sector generates a large amount of recyclable material and that much of this material is currently being landfilled. Just as all the residents' waste collection is handled through a municipal contract, the Committee believes the City could create a single commercial contract for all the businesses. This commercial contract would provide recycling services with garbage service at equitable prices. Furthermore, a single collection company would reduce the number of collection trucks on City streets. These heavy trucks are responsible for a significant portion of the damage to City streets and reducing them would reduce repairs to the streets. Fewer collection runs would also relieve traffic congestion and reduce overall emissions. Not all waste collection companies offer recycling or they cease offering it when the recycling market is in a downturn (like the past few months). With a commercial contract — also known as a franchise agreement, the selected vendor would be required by the City to recycle regardless of market fluctuations. The City of Yorkville staff briefed the committee on recent changes to state law related to creating a citywide commercial recycling franchise. This process will take over 15 months to pursue, as it requires notification to all waste haulers currently servicing Yorkville businesses, a public hearing, and RFP. The Committee understands the short-term work this will create for the City staff but such a project will benefit to the community as a whole for the foreseeable future. In the meantime, the Committee recommends that the City encourage all businesses, schools, and organizations to recycle. Action Requested: Ask staff to begin the franchise agreement process and encourage all businesses, schools and organizations to recycle as much as possible.

Multi-year projects are listed with their total cost only in the year they are scheduled to begin, unless they will be constructed as separate,phased projects. All project costs are for construction and related construction engineering unless indicated otherwise. Debt service for past projects is not listed. Projects scheduled for developer funding may be delayed due to the lack of funding. Costs for ongoing and imminent project were updated based on best available information. Park-related projects are not listed. Proposed major updates to last year's approved plan are as follows: General • The purpose of listing projects for the current 2009-2010 fiscal year is to give a realistic view of what we are capable of funding. The Capital Improvement Program for future fiscal years is very aggressive, and depends largely on developer funding and some borrowing. • Various projects were moved forward or back based on available funding or on the progress of our overall water, sanitary sewer, and roadway programs. • Project required for or primarily funded by new development for the most part have been moved back towards the end the 6-year timeframe. Water • No new construction projects. • The Newlyweds Foods watermain replacement was moved forward to FY 11-12 to coincide with the Route 47 watermain relocation project. Sanitary • No new construction projects. • Moved the SSES projects forward to FY 10-11 and 11-12 due to YBSD's plan to move ahead with expansion of the wastewater treatment plant. • The Zangler sanitary sewer project was deleted because the property was not sold. We have added, however, easement acquisition as a capital project for this property. Streets • No new construction projects. • The River Road Bridge project was moved to back to coincide with proposed county and state funding. Miscellaneous • The two Safe Routes to Schools grant projects were added in FY 10- 11 and 11 - 12. In general, no new projects were added to the Capital Improvement Program this year due to the economic downturn and the corresponding drop in funding sources. Funding for many projects is uncertain. There are two projects (Game Farm/Somonauk and Route 47 roadway reconstructions) currently under design and scheduled for construction in the next few years that will require very significant city funding. We have limited ability to influence the timelines of these projects without jeopardizing outside funding. We need to evaluate our funding options so we are ready to proceed once these projects are cleared for construction.

Council Action Previously Taken: Date of Action: Action Taken: Item Number: Type of Vote Required: Majority Council Action Requested: Approval Submitted by: Joe Wywrot Engineering Name Department Agenda Item Notes: c,T yin Memorandum EST. \ 1836 To: Brendan McLaughlin, City A stra r From: Joe Wywrot, City Engineer 1� p CC: Kathy Orr, City Attorney Lisa Pickering, Deputy City Clerk <LE Date: August 31,2009 Subject: Bond/Letter of Credit Reduction Policy At their meeting on August 18d,the Public Works Committee discussed a potential revision to our current bond/letter of credit reduction policy. The current policy is to use the engineer's estimate of probable cost(EOPQ that is approved at the time of final plan preparation as the basis for calculating the bond/letter of credit amount and reductions to the amount of the bond/letter of credit. The bond/letter of credit may be reduced per Resolution 2009-15 (attached) based on work that is substantially completed. The proposed change to the policy is to require that the unit pricing of the EOPC be adjusted whenever a reduction is requested by applying an inflation factor, from the date that the EOPC was prepared or most recently updated,to the date of the reduction. The inflation factor would be applied uniformly across all unit pricing in the EOPC. I recommend that we use the Engineering News Record Construction Cost Index for the adjustment calculations. Please place this item on the September 15,2009 Public Works Committee agenda for discussion. RESOLUTION NO. 2009- RESOLUTION MODIFYING A POLICY REGARDING PROCEDURE AND AUTHORITY TO REDUCE LETTERS OF CREDIT AND PERFORMANCE BONDS FOR CONSTRUCTION OF LAND IMPROVEMENTS WHEREAS, the United City of Yorkville requires that land developers provide security for the successful completion of the installation of public and quasi-public (together also known as land improvements), including but not limited to streets, curbs, sidewalks, watermains, storm and sanitary sewers, streetlights, detention basins, landscaping, etc., and WHEREAS, said security is typically established either by means of a Letter of Credit or a Performance Bond, and WHEREAS, from time to time, a developer will seek reduction in the principal amount of the Letter of Credit or the Performance Bond amount after substantial completion of a portion of the land improvements which are the responsibility of the developer, and WHEREAS, current practice established by Resolution 2005-67 involves an approval of the City Engineer's recommendation by the Mayor and City Council, which is unnecessary as it is not a legislative act but an administrative calculation of sufficient security to ensure completion of land improvements by the developer. BE IT HEREBY RESOLVED BY THE MAYOR AND CITY COUNCIL OF THE UNITED CITY OF YORKVILLE, KENDALL COUNTY, ILLINOIS : 1 . Resolution No. 2005-67 is hereby repealed in its entirety. 2. The approval process for Letter of Credit and/or Performance Bond reductions shall be as follows: a. The City Engineer shall issue a written recommendation including the basis for approving, denying, or modifying a request for reduction. Said written recommendation shall include the amount of the reduction and the remaining amount of the Letter of Credit and/or Performance Bond. b. The City Engineer' s written recommendation shall be forwarded to the City Administrator for approval. c. Upon the City Administrator's concurrence with the City Engineer's recommendation, the reduction shall be deemed approved or denied and the City Engineer is authorized to issue a letter to implement the decision. d. In the event the City Administrator does not concur with the City Engineer's recommendation, the Mayor shall have final authority to approve or deny the City Engineer's recommendation. e. A developer may appeal the decision of the City Administrator to the Mayor, who shall review and make a final determination to affirm or reverse the City Administrator's initial decision. f. The City Administrator or designee shall issue reports, quarterly or more frequently as deemed appropriate, to the Mayor and City Council that summarize Letter of Credit and/or Performance Bond reduction requests that have been received and actions taken pursuant to those requests. 3. Final acceptance/approval of land improvements and corresponding reduction/ release of Letters of Credit and/or Performance Bonds for developments whose initial Letter of Credit or Performance Bond amounts is less than $1 ,000,000 shall also be handled in accordance with the procedures established by this policy. Final acceptance/approval of land improvements and corresponding reduction/release of Letters of Credit and/or Performance Bonds for developments whose initial Letter of Credit or Performance Bond amounts are $ 1 ,000,000 or more shall be placed before the City Council for approval. 4. The retainage used in calculations for Letters of Credit and/or Performance Bond reductions is hereby increased from 15% to 20%.
