The Commission reviewed the Envision process and prioritized their focus topics to be provided to the City Council. After reviewing the Envision -guided recommendations, the Environmental Commission passed the following motion: The Environmental Commission would like the City to "install recycling receptacles in all city parks and trash receptacles at the entrances to all nature areas." In responding to the motion, the Public Works Director requested staff investigate the history of recycling in Golden Valley parks and surrounding communities' past experiences with this type of request. Public Works Maintenance staff provides trash receptacles at all of the 24 park/activity areas and at approximately five of the nine nature areas. Maintenance staff has provided outdoor recycling containers at special events, on a request basis, on a few occasions over the last ten years. The efforts resulted in limited success due to the following issues related to outdoor recycling containers: 1. Recycling materials mixed with significant contaminants, including animal feces, resulting in the majority of the product being placed in the waste stream rather than being recycled. 2. Staff receiving complaints from park users of bee problems related to high concentration of opened containers in outdoor recycling bins. Similar concerns have been experienced by surrounding communities who have attempted to provide outdoor recycling receptacles at city parks. G:\Environmental Commission\Correspondence\Memos\2006\RecyclingMotion051806.doc Staff has learned that the City of St. Louis Park, with the help of a grant from Hennepin County, will be conducting a study this summer to investigate ways to successfully promote and provide outdoor recycling receptacles that can generate a cleaner recycling stream and reduced bee problems. The final report will be completed by September 29, 2006. Attached to this memo is a map that documents the locations of existing trash receptacles in Golden Valley's parks and nature areas. At the Commission's April meeting, the Commission requested that this item be placed on the June agenda. C: Jeannine Clancy, Director of Public Works Tom Klatt, Public Works Maintenance Manager Ron Hammer, Park Maintenance Supervisor Rick Jacobson, Director of Parks & Recreation GAEnvironmental Commission\Correspondence\Memos\2006\RecyclingMotion051806.doc Trash Receptacles at City Parks, Trails and Nature Areas (see map on reverse) Park Maintenance currently manages 150+ metal trash receptacles at City parks, trails and nature areas. 2. It takes one two -person crew eight hours, one day per week to transport and empty the receptacles into a dumpster at the golf maintenance operations building. 3. The trash receptacles are maintained over a 6 -month time period: Estimated labor for two full-time staff for 3 -month time period $6,720 Estimated labor for two part-time staff for 3 -month time period $1,288 $8,000 4. In addition to the existing 10 locations, the Park Maintenance Supervisor has identified 30 potential additional locations at nature areas and trails for installation of trash receptacles (see map on reserve for existing and potential locations). 5. If 30 additional trash receptacles are added at the locations proposed, the Park Maintenance Supervisor anticipates the following: ➢ An additional three hours per week for one two -person crew to empty the 30 additional trash receptacles. ➢ One additional dumpster needed from trash hauler to handle the added waste.

Focus Areas • Problems caused by cross -connected sump pumps • Problems with aging City -owned sanitary sewer facilities and with an aging and at -capacity interceptor system • Changes in laws regarding the building code, the environment, etc • Impact on Golden Valley (costs, surcharges, demand charges, effects on future redevelopment) • Need for public education about cross -connections and related issues • Responsibilities of property owner, City, and Met Council • Responsibility to the environment 2. Mission The City of Golden Valley must reduce its 1/1 into the sanitary sewer system to comply with Metropolitan Council requirements, minimize and eliminate the surcharge, and remain friendly to the environment. To accomplish this, the City must raise public awareness about 1/1 and related issues, and generate public support for and compliance with the City's program to reduce 1/I. 3. Goals and Objectives • Help public understand 1/1 and related issues and how they impact the community and the region. • Explain sanitary sewer system in general and the aging and capacity issues with the City and Met Council system in particular, and problems caused by cross -connected sump pumps • Educate public about City's efforts to reduce 1/I. Build public support for City's 1/1 reduction efforts. Explain individual property owners' responsibility for helping reduce 1/1. • Build public support for individual property owner responsibility for helping reduce 1/1. • Encourage property owners to participate in and comply with 1/1 inspection program. • Educate public about City's efforts to be responsible stewards of the environment. • Encourage citizens to consider and act upon their responsibility to the environment. 4. Potential Strategies (1 = high priority, 2 = medium priority, 3 = low priority) • Educational video that provides overview of problem and solution (for use on cable TV, neighborhood meetings, etc) • Short video PSAs for cable TV and Web site to encourage action • Include questions on City survey (Fall 2006) to determine level of public awareness, anticipated cooperation level, etc) • Web site material • Neighborhood information meetings • City newsletter articles • Press releases to Post and Cable 12 • Increase awareness at Pavement Management information meetings • Share case studies of 1/1 problems in other parts of the US • Use "Leak Ericson" as a mascot and symbol for 1/1 program :,communications Plan 4.1 Strengths 4.2 Challenges Legitimate issue m 0 Population's lack of knowledge about problem Knowledgeable staff 0 Desire to buy way out of problem • We're building a plan 0 Population's lack of knowledge about system and how it • Established City information outlets (publication, works cable TV, web) • Costs to property • Community paper and community TV 0 Lack of funding • Engaged community 0 Blamestorming • High level of City service 0 Distrust of government • Success of meter change -out program 0 Working with other Cities (New Hope, Robbinsdale, Mpls) • Success of pavement management education • • 1• 5.

Key Messages • Cross -connected sump pumps are illegal and harm homeowners, neighborhoods, and the entire community. • Illegal sump connections dump clear water into the sanitary sewer system, which sends it to the waste water treatment plant. Treating this clear water is unnecessary and increases your sewer charges. • Cross -connected sump pumps add water to a sanitary sewer system that wasn't designed to handle it. Overflows can cause sewer back-ups in people's basements—maybe even your own. • Properly connected sump pumps discharge to the lawn or the storm sewer system, not to a drain or sanitary sewer pipe in the house. • During the rainy season (March through October), cross -connected sump pumps increase the flow of clear water through Golden Valley's sanitary sewer system two -fold. • If Golden Valley doesn't get its 1/1 under control, its utility customers will pay $380,000 per year in additional sewer charges starting in 2008. • You can help reduce 1/1 in Golden Valley by making sure your sump pump is discharging properly to your lawn or the storm sewer system. • The City of Golden Valley's sump pump inspection program will help citizens determine if their sumps are properly connected. 2 7.

Storm water pipes are closer to the surface than sanitary sewer or water pipes because the water they handle is continually flowing downhill to the nearest outlet (ie, a lake, river, creek, pond, or wetland). Water going through storm water catch basins in the street is not treated before it is returned to the environment. However, devices such as storm water ponds help filter out sediment and pollutants before the water reaches natural waterways. iLaiiiii,011im Wastewater Wastewater from Golden Valley travels through the City's sanitary sewer system and goes to the Metropolitan Wastewate Treatment Plant, located on the Mississipl ver in St Paul.Wastewater treatment provided by the Metropolitan Council through the Metropolitan Council Environmental Services Division (MCES). The Metro Plant is the largest wastewater treatment facility in Minnesota, processing about 300 million gallons of wastewater every day from 104 communities and 800 industries. Wastewater treatment is a key service for residential, commercial, and industrial development and an important defense in protecting the public health.

The basic sump system includes drain tile, a sump pit, a sump pump, a float or switch, and a drain Iine.The sump pit extends below the slab and collects surface water that enters the basement/crawl space or groundwater that'to the sl0 4 Homeowners commonly use sump pumps in their basements to battle moisture and flooding issues. However, water from sump pumps should NOT be discharged into the sanitary sewer system.That's called a cross connection, and it results in higher sewer charges. The Problem With Cross Connections When a sump pump is connected to a sanitary sewer line it is called a cross connection. Often, t is a hose leading from the sump to a laundry or a floor drain. As you may know, water at goes down any drain in your house leads to the sanitary sewer system and eventually ends up at a wastewater treatment plant, where it is treated before being released back into the environment. Why You Should Care It comes down to paying to treat water that doesn't need it. Sump pump water is what engineers call "clear Water," most often rain water, ground water, snow melt.This water flows directly into are streams, ponds, and Iakes.Water from sinks, showers, tubs, toilets, and washing machines is wastewater and must be treated before it is discharged into the environment. Clear water, such as that from a sump pump, overloads the sanitary sewer system. During the rainy season (March through October), this clear water increases the flow through Golden Valley's sanitary sewer system one to two times the usual amount, primarily because of cross connections. Since sanitary sewer rates are based on the number of gallons that flow through the City sanitery sewer collection system and into the MCES water treatment system, treating clear water is costly. RedirectingYour Sump Pump Connection Sump pumps should drain into the City's storm sewer system through one of two methods: • a direct connection (a pipe from the house to the main storm sewer line), if available • directly onto the ground (preferably 20 feet from the house and not into a neighbor's yard) The illustration below depicts a proper sump pump connection. FOUNDATION ROOF DOWNSPOUTS WITH EXTENSIONS INTERIOR WATER COLLECTION 1 1/2" RIGID PIPE /FOR UBBER COUPLING PUMP REMOVAL 1 112" PIPE PLUG TO STREET (OPTIONAL) FLEXIBLE PIPE WITH ADAPTER The Storm Sewer System Because developed areas like Golden Valley lave more impervious surfaces (houses, driveways, streets, sidewalks, buildings, parking lots, etc), there are fewer places where water from rain and melting snow can seep into the ground. Storm sewer systems are designed to collect this run- off and prevent it from flooding the city's streets, homes, and businesses. ;, Run-off enters Golden Valley's storm sewer system through sump manholes and storm water drains (called gutters by some and catch basins by the City). From there it is directed to pipes under the street system and into area waterways (see details inside). Avoiding Problems When catch basins are clogged with leav and yard waste, it prevents run-off from reaching the storm sewer system and ca cause flooding. Also, as run-off moves across streets, roofs, parking lots, lawns, driveys, and other surfaces, it picks up pollutants (soil, leaves, grass clippings, pet waste, o , fertilizers, pesticides, herbicides, litter, etc) and carries them into the storm sewer system. This water receives no chemical treatment of any kind before it is discharged into a water body, such as Bassett Creek. Many of these problems can be avoided through regular maintenance and by being careful about leaving possible pollutants on your lawn, driveway, or street. This brochure provides information to help you understand how the storm sewer system works and how you can help reduce the risk of a storm backup (flooding) and surface water pollution. (See inside for more information on pollution prevention.) You Can Help! The City of Golden Valley has several opportunities for residents who want to help protect water resources. For more information, contact the environmental coordinator at 763-593-8046. Storm Drain Inlet Program To prevent pollutants from entering the storm drain on your street, keep it clear of debris. Or, sign up for Golden Valley's Storm Drain Stenciling Program. Volunteers stencil a fish symbol, combined with a "Dump No Waste" message, near storm drains that lead to neighborhood ponds, lakes, or Bassett Creek to increase surface water awareness and remind citizens of their role in protecting water resources. Storm Drain Outlet Program The best defense of water resources is to prevent pollutants from getting there, and storm drain outlets are the last frontier. If you live near a lake, pond, or stream with an outlet basin, perhaps this is where you can help most. City staff is available to assist, coordinate, and encourage volunteers to adopt certain storm drain outlets and to set up a system to notify the City of operation and maintenance concerns and illicit discharges.

Elk BRAINS TO tOIE r Maintaining The Storm Sewer System Golden Valley's storm sewer system includ around 1,000 catch basins and about 90 m f pipe under the street system. These pipes, most of which were installed during the 1960s, range in size from 12 to 84 inches in diameter. After runoff enters a catch basin or a sump manhole, it heads down a lateral pipe to the main pipes. These pipes are closer to the surface than sanitary sewer or water pipes because the water they handle is continually flowing downhill to the nearest outlet (ie, a lake, river, creek, pond, or wetland). To keep storm water flowing smoothly, the City regularly inspects and cleans catch basins and outlets, but crews may not be able to attend all of them if an emergency arises. If you have a catch asin or storm drain outlet adjacent to your property, you can help the City by keeping debris from the opening (see back panel for details). Run-off enters the y water cycle y Avoid Common Causes Of Surface Water Pollution No matter where you live, you are in a watershed. A watershed is an area where storm water run-off goes to the same place. Most all the water that falls onto the surface of Golden Valley, from precipitation tilkvn watering, goes into Bassett Creek. A small portion of the city drains into Minnehaha Creek. • AIM the way, it moves over pavement, streets, roof tops, and through private and public lawns, collecting anything in its path—chemicals, leaves, fertilizers, grass clippings, etc. According to the Lake Superior Regional Stormwater Protection Team, polluted run-off affects 90% of our inland lakes, 40% of our streams, and much of our groundwater, making it the number one urban water pollution problem. Because run-off is not treated, cities use devices such as storm water ponds to filter some pollutants before they can reach natural waterways. Your actions also affect the future of our water bodies. Follow the tips below to help minimize pollutants in storm water run-off and, ultimately, in natural waterways. Lawns, Gardens, and Compost When mowing your lawn, mulch grass clippings or direct them onto the lawn, not the street. Start a compost for yard waste or take it to a collection site. Minimize the use of fertilizer and herbicides in your yard. Pets Clean up after pets. Sand and Gravel Sweep up sand and gravel and put it in the trash or mix it in the garden to loosen u that clay soil. Never hose sand or gravel into the street. Storm Drains Clean up around the storm drain in the street and report clogged drains to the City at 763-593-8075. Never dump anything down a storm sewer drain. Vehicles Wash your car on the lawn or take it to a car wash where the water Condensation is treated before it's discharged. Keep vehicles in good condition to prevent them from leaking oil and chemicals on the streets. Shorelines If you live on shoreline, plant a buffer of Condensation vegetation. • Rain Consider planting a rain garden or • WATER CYCLE collecting water in a rain barrel. / > Transpiration Common Pollutants In Run-off • Sediment (soil and sand) Evaporation • Yard waste (leaves, Tgrass, etc) and litter • Human/animal waste Storm Drain Inlet • Chemicals (herbicides, (Catch Basin) Storm Drain Bassett Creek pesticides, detergents, Outlet oil, grease, road salt) The Sanitary Sewer System Sanitary sewers get no respect. People generally take them for granted—that is, until there's a problem. Blocked sinks, overflowing toilets, and flooded basements are all unpleasant emergencies and expensive problems. Anything that goes down an indoor drain in your house (sinks, washing machine, toilets, bathtubs, floor drains) is considered wastewater, and it enters the sanitary sewer system. It then journeys through a branching network of pipes and manholes and is ultimately delivered to a wastewater treatment plant (see details inside). Avoiding Problems Sometimes substances or objects that are flushed or washed down drains clog the system, resulting in sewer problems and backups. Slow or gurgling drains and sewer odors are two signs of potential sewer problems. If any of these signs occur in your home, call a sewer cleani service and have your sewer inspected and/or cleaned before a backup occurs Please notify the City of Golden Valley Public Works Utilities Division at 763- 593-8075 when you've had your sewer service cleaned. You Can Help! You can help maintain the City's overall sanitary sewer system by having your private sewer line serviced regularly. Please notify City of Golden Valley Public Works Utilities Division at 763-593-8075 when you've had your sewer service cleaned and whether or not roots were removed. Roots often travel downstream to a manhole, where they can cause a back-up to the main line.

T SEDTEMbER OciobER 2005 GoIdEN VA«Ey CITYNEWS Notice Is Given: Keep A Lid On Wastewater GoIdEN VAREV CITyNEws The cost of everything is going up, or so it seems, including the cost of necessities such as water. In every metro community there's a charge for disposing of clean water (storm water) and treat- ing water that's been used (wastewater). In Golden Valley, charges for unnecessary treating of clean water are threatening to blow the lid off both our manholes and our pocketbooks. Wastewater from homes and businesses must be treated before it goes back into the environ- ment. Golden Valley's sanitary sewer system, like those in 103 other communities, connects to the Metropolitan Council Environmental Services (MCES) regional interceptor system, and its wastewater is treated by the Metro Wastewater Plant (see below left). Golden Valley is also one of about 60 communities that overloads the treatment system with clean water following heavy rains. Those in the know refer to this as inflow and infiltration (1/1). The Drain Of Inflow And Infiltration (I/I) There are two major sources of inflow and infiltration (1/1) surpluses. Inflow is usually traced to sump pumps (used by many home- owners to keep groundwater out of their basements) that are directed (cross -connected) to discharge into the City's sanitary sewer system. They are often connected via a hose leading from the sump to a laundry tub or a floor drain. Infiltration occurs when groundwater seeps into sanitary sewer pipes through cracks orjoints. At current 1/1 rates, the wastewater treatment system's capac- t cannot meet projected needs, which, along with cost and pollution control, are the three main components of the 1/1 problem. --ost Treating clean run-off and ground water wastes about $300 to $400 million annually, according to the MCES. If the additional storm water exceeds the sanitary sewer system's capacity and causes wastewater to spill out of a manhole or back up into base- ments, there are also clean-up costs and federal and state fines. "We simply can't afford to build enough [sanitary] sewer capacity to accommodate the excess flow from clear water, so we need to fix the problem at its source," says Met Council Chair Peter Bell. Capacity For an area to develop, it needs systems that both deliver water and remove wastewater. Currently, metro area people, businesses, industries, and farms use 384 million gallons of potable (drinkable) water daily (70 to 90 percent of which ends up as wastewater). An estimated million more people in the next 25 years will up consumption to 496 million gallons daily. Problem is, excess clean water is using up the sanitary sewer system capacity designed to handle projected growth. "We need to reserve [sanitary] sewer capacity for new homes and businesses;' adds Bell. Pollution Control MCES discharges 300 million gallons of treated wastewater daily into the Mississippi, Minnesota, St Croix, and Vermillion Rivers. This discharge is carefully monitored to meet federal requirements, and the MCES has lam, had excellent results, but more discharged wastewater means more pollution load, thus the strain on Minneso- ta's treasured waterways. Located e The most cost-effective solution to 1/I, says MCES general manager Bill Moore, is a region -wide on the ale , effort to disconnect sump pumps and foundation drains connected to sanitary sewers and to Mississippi rj, repair leaky sanitary sewer pipes.

Improve- ments to the storm sewer system help the City control inflow by allowing residents to connect their sump discharge into the storm sewer system through the City's Pavement Management Program. See the article on page 12 for more infor- mation about the City's sanitary and storm sewer systems. As directed by the Met Council, the City (along with other Met Council communities) will update its Compre- hensive Plan by 2008 to include a surface -water management plan and a comprehensive sanitary sewer plan, a program to reduce groundwater and rainwater in sanitary sewers, and a plan to manage septic tanks.

UNdERSTANdiNCt WASTEWATER ANd GEAR WATER From early spring and throughout the summer, the sanitary sewer system handles one to two times its normal volume of water. The problem is that the additional volume, mostly from sump pumps, is not the wastewater intended for the system—it's clear water.

We want clean, safe water to come out of our faucets, and we want it to drain away when we're done using it. We don't want to worry about where everything goes after we flush the toilet, as long as it goes away. When we get in our cars, we expect streets (preferably in good repair) that allow us to get to our various destinations. We don't want to worry about flooding. In our free time, we like to have access to public parks and trails for recreation. Oh yeah, we want our urban landscape to have some nice trees, too, so it doesn't seem like we're in a city. In a busy world, it's easy to take these basics for granted. Generally called infrastructure, they are the facilities and framework that provide a foundation for human civilization. storm Water System As rain, melting snow, and other precipitation runs off streets, roofs, OF parking lots, lawns, drive- ways, and other surfaces, it is directed to the storm water sys- tem through storm drains in and under the gutters (catch basins) of the street system. Water going through storm water catch basins in the street is not treated before it is returned to the environment. How- ever, devices such as storm water ponds help filter out sediment and pollutants before the water reaches natural waterways. Public Works crews maintain approximately 90 miles ' of storm water piping and about 1,000 catch basins. They also maintain Bassett Creek, which meanders through the community from the west to east, by checking it for debris that could restrict the flow. The City of Golden Valley administers several storm water management programs, including pond cleaning, rear yard drain- age, sump pump discharge, street sweeping, storm water system cleaning, and installation of sump catch basins. Through it's Environmental Division, Public Works educates the community about water quality issues as they relate to storm water runoff (see phos- phorus article on page 5). 'street and Sidewalk System Street maintenance is one of the biggest, and costli- est, responsibilities of City government. Its also one of the most necessary. Public Works must keep approximately 120 miles of streets and 31 miles of sidewalk at an adequate level of service and safety. And because streets deteriorate as they age, Golden Valley's Pavement Management Program (PMP) recommends rehabilitating streets that require costlier ongoing maintenance. Staff then systematically man- ages further maintenance (sealcoating and overlays) on the new pavement to provide a longer street lifespan at the lowest possible cost to the taxpaying public (see sealcoating article on page 9). Under Golden Valley's PMP, Public Works evalu- ates all city streets based on their need for mainte- nance or rehabilitation. Priority is given to streets, or groupings of streets, that have the highest need. Most of Golden Valley's neediest streets are more than 30 years old and were constructed using methods that differed greatly from today's standards. Streets not constructed to current standards (includ- ing concrete curb and gutter) will be reconstructed or reclaimed at some time during the life of the PMP On the maintenance side, Public Works crews repair potholes and support sealcoating and overlay efforts to keep streets safe and help them last longer. Crews sweep and clean streets from March to Novem- ber to keep the city clean and prevent debris from entering the storm water system. In the winter the focus shifts to keeping streets safe and passable. Besides standard maintenance issues, crews handle major weather events about 10 times each winter, driving about 450 miles each time to plow and sand the streets and clear sidewalks.

Many of these areas include amenities such as shelter buildings, ball fields, game or sport courts, playground equipment, and ice rinks. As caretakers of these areas, Public Works crews provide all general upkeep and improvements, including mowing grass, trimming bushes and trees, maintaining park shelters, grooming ball fields, and more. In addition, crews maintain nearly 47 miles of trails. Each winter efforts turn to providing Golden Valley residents with some of the best ice rinks in the metro area.

For more information on the where the City gets its water, see the article on page 3 and the Water Quality Report inserted in this newslet- ter, or go to jwcontap.org. Wastewater treatment is a key service for residential, commercial, and indus- trial development and an important defense in protecting public health. Golden Valley's sanitary sewer system carries wastewater through 120 miles of pipe to the Metropolitan Wastewater Treatment Plant in St Paul. The system consists of gravity pipes (including trunk lines and lateral lines), force mains, and lift stations. Homeowners can help control sewage treatment costs by making sure the sump pumps in their basements do NOT discharge into the sanitary sewer system (generally via a laundry tub or floor drain). Instead, sump pumps should drain into the City's storm water sys- tem through a direct connection to the main storm water line or directly onto the ground (preferably 20 feet from the house and not into a neighbor's yard).

Forestry Program Golden Valley's many wooded residential areas are important visual, aesthetic, and economic resources and add significantly to the quality of life and value of property in the community. Just as streets, sewers, public buildings, and recreational facilities are part of a community's infrastructure, so are publicly owned trees. Direct benefits are usually associated with energy costs—tree shade can reduce air conditioning costs by 15 to 50% and heating costs as much as 30%. The indirect economic benefits of trees are even greater. On average, an acre of trees can store 2.6 tons of carbon (pollution) annually and generate enough oxygen daily for 18 people. Models show that in 50 years, one tree can gener- ate $30,000 in oxygen, recycle $35,000 of water, and remove $60,000 of air pollution.

E7 ,I GOLdEN VA«Ey OgNEWs SEpTEMbER OCTOBER 2002 PAGE 5 Check Your Sump Pump F.jr Cross Connections Sump pump systems are designed to capture surface or ground water that enters base- ments or crawl spaces and pump it away from the house. Homeowners commonly use sump pumps to battle moisture and flooding issues. However, when sump water is directed into the sanitary sewer system, it goes to the wastewater treatment plant and results in higher sewer charges. That's called a cross connection, and simple corrective actions can save you and your community thousands of dollars. A cross connection is often a hose leading from the sump to a laundry tub or a floor drain. Water that goes down any drain in your house leads to the sanitary sewer system and eventually ends up at a wastewater treatment plant, where it is treated before being released back into the environment. Residents pay for wastewater treatment through their water bill. Since sump pump water is what engineers call "clear water" (most often rainwater, ground water, or snow melt), it does not need to 6e treated and can 6e returned as is to area streams, rivers, and lakes through the City's storm water system. REdiRECTINq YOUR SUMP PUMP CONNECTION To begin, locate your sump pump and inspect the connection. If you find it is cross - connected, reroute it to City's storm sewer system through one of two methods: • a direct connection (a pipe from the house to the main storm sewer line), if avail- �kle • :ctly onto the ground (preferably 20 feet from the house and not into a neigh- bor's yard) WhAT TIDE CiTy Is DoiNc, To HE[p Residents in Golden Valley's Pavement Management Program (PMP) areas may have the opportunity to participate in the City's new program that establishes a direct connection from residents' yards to the City's storm water system. While the street work is being done, crews install an eight -inch plastic pipe behind the curb with a four - inch pipe to the property line where possi6le. Residents can connect their sump output directly to this pipe, which will help keep clear water out of the sanitary sewer system, off the street, and away from basements. For more information on City's new sump pump program or cross connections in general, call Utilities Maintenance at 763-593-8075. Also check the City web site at www.ci.golden-valley.mn.us/streets/sumppumps.ktm, which features an animated video (requires Flash plug-in) illustrating cross connections and how to repair them. 10f r_— FAIL How MAINTENANCE ChEckhST ❑ Repair damage to roof and valleys. ❑ Have fireplaces professionally cleaned. ❑ Seal driveway, sidewalk, foundation, masonry, and exterior cracks. ❑ Clean septic tanks every two years. ❑ Replace loose and missing putty and deteriorating weather-stripping, and caulk around doors and windows. ❑ Check all doors and window hard- ware.

If the valves are not working properly, have them repaired by a plumber first. luring Installation I Make sure an adult (age 18 or older) is at home when the installer arrives. A typical installation with no problems takes about 45 minutes with no additional expense to City residents. If the meter installer encounters a faulty valve, the property owner will be notified and a new appoint- ment will be scheduled after the home- owner has had the valves repaired. x more information about the new water eters and for updates on the replacement ocess, watch upcoming editions of 'News or click to the City web site -!A, golden-valley.mn.usl.

Homeowners commonly use sump pumps in their basements to battle moisture and flooding issues. Anatomy of a However, water from sump pumps should NOT be discharged into the sanitary sewer system. That's S u lvi p called a cross connection, and it results in higher sewer charges. Sump pump systems are designed to capture Sump pumps should drain into the City's storm surface or ground water sewer system through one of two methods: that enters basements or crawl spaces and pump it O a direct connection (a pipe from the house to the away from the house. main storm sewer line), if available O directly onto the ground (preferably 20 feet from The basic sump system the house and not into a neighbor's yard) includes drain tile, a sump pit, a sump pump, a float The Difference Between Wastewater and or switch, and a drain line. Clear Water The sump pit extends Any water that goes down any drain in your house— below the slab and sinks, showers, tubs, toilets, and washing ma- collects surface water that chines— is wastewater that must be treated before it enters the basement/crawl is discharged into the environment. space or groundwater that rises to the slab. Golden Valley wastewater travels through the City's sanitary sewer system to the Metropolitan Wastewa- ter Treatment Plant, located on the Mississippi River in St Paul. Water treatment is provided by the Metropolitan Council through the Metropolitan Council Environmental Services Division (MCES), the largest wastewater treatment facility in Minnesota. It processes about 300 million gallons of wastewater daily from 104 communities and 800 industries. Sump pump water is what engineers call "clear water," just like rain water, ground water, or snow melt. Clear water is directed to the storm water system through storm drains in and under the gutters (catch basins) of the street system. The water going through storm water catch basins in the street is not treated before it is returned to the environment. The Problem With Cross Connections A cross -connected sump pump is often a hose leading from the sump to a laundry tub or a floor drain. When sump water is pumped down a drain, it overloads the sanitary sewer system. During the rainy season (March through October), this clear water increases the flow through Golden Valley's sanitary sewer system one to two times the usual amount, primarily because of cross connections. It comes down to paying to treat water that doesn't need it. Since sanitary sewer rates are based on the number of gallons that flow through the City sanitary sewer collection system and into the MCES water treatment system, treating clear water is costly.

C ity to Enforce Lawn and Drainage Ordinances Understanding and complying with City ordinances regarding lawn maintenance and sump pump discharge will help residents maintain neighborhood relations as well as promote the safety and livability of Golden Valley. Here's an overview. Lawn Ordinance City code requires Golden Valley residents to keep their lawns mowed and maintained. The maximum height for a lawn is eight inches. If the grass is allowed to grow taller, the resident will be notified of the violation. The resident then has five days from the notification to correct the violation. If there is no compliance, the City will have the lawn mowed and send the bill to the homeowner. To avoid violating this ordinance, have your lawn mowed by someone else if you plan to be away from home for more than two weeks. If the City is unable to reach you, it will have the lawn mowed in your absence and send the bill to you. Besides ordinance violation, there are other reasons to tend your lawn. A trimmed lawn is healthier; it prevents soil erosion, absorbs and dilutes pollution from the air, and traps contaminants that would otherwise run through storm sewers into our waterways. Well-maintained lawns look great and need fewer chemicals, as well. To notify the City of a lawn maintenance violation, call Park Maintenance at 593-8045. Or, if you have questions about starting, maintaining, or correcting a problem with your own lawn, try the University of Minnesota's Yard and Garden Line at (612) 624-4771. Drainage Ordinance Golden Valley City Code prohibits the discharge of ground water or roof drainage to any city street or right-of-way. This includes sump pump discharges from basements. This type of discharge poses a threat to public safety because the pooled water creates breeding grounds for insects in the summer and problems with icing in the winter. Frequent and substantial discharge for more than 14 days is prohibited. Extended discharge will cause the City to give written notice to discontinue. Noncompliance can lead to misdemeanor charges punishable by fines of up to $750 and up to 90 days in jail, or both. City code also prohibits any individual or business from discharging groundwater to the sanitary sewer system. This minimizes the need for very expensive treatment facilities metro -wide for water that does not need treatment. Property owners who have no other physical way to handle the groundwater discharge (affordability is not a consideration) may connect to the sanitary sewer by approval of the Director of Public Works. However, the property owners must cover all costs associ- ated with the connection, including required metering and piping. Property owners will then be charged for all additional discharge to the sanitary sewer on their utility bills. If you have questions about this ordinance, contact the City Engineer at 593-8030. iTyN EWS input Property Maintenance Over the past year, CityNews has run articles informing residents about property maintenance standards—preventive requirements that help communities maintain their housing stock. Such standards are becoming increasingly important in mature commu- nities like Golden Valley, where a significant percentage of homes are showing signs of age. By staying on top of maintenance issues, residents can preserve and enhance their investment in their property, which benefits -!m personally and the mmunity as a whole. INFORMATiO P N MIEETiNqS roperty maintenance issues are high on the list of City Council goals for the com- munity, and last year the Council adopted a prop- erty maintenance code for multiple -dwelling units. The City Council is now con- sidering a property mainte- nance code for single- and two-family homes.

Input received at these meetings will help the Council in its upcoming deliberation on a residential property maintenance code. These meetings will also provide residents an opportunity to learn about the state of the community's housing stock and receive information on current rehabilita- tion resources available to Golden Valley residents. AdOpTINCt A COBE Cities find that property maintenance codes help protect residents from poten- tially hazardous conditions and help maintain the vitality and integrity of the community's housing stock. For example, when a City adopts maintenance stan- dards for exterior walls, roofs, gutters, decks, doors, and windows, property owners are required to keep these items in a good state of repair. If violations are not ected in a reasonable time, the City _y issue citations. ENFORCEMENT Property maintenance codes are enforced through proactive inspections. When a City inspector determines a property is out of compliance according to the City ordinance, he or she will issue a correction order to the responsible party of that property. The compliance order will state a reasonable amount of time for corrections to be made. Non-compli- ance will result in a Fine assessed through an administrative citation (fines will not exceed the maximum penalty for misde- meanor violation by state law).

A "Fit City" provides oppor- tunities for physical activity to people who live, work, and play in the community. This goal is to support and encourage residents to be more physically active and improve the overall health of the community. Cities achieving a Governor's Fit City designation had to meet several Minnesota Department of Health criteria, such as having a City Council -adopted resolution affirm- ing activity -friendly commitments, having inviting places to walk, sponsoring at least one fitness activity, and developing recreation areas that encourage fitness. "We're proud Golden Valley was considered a good candidate for the Fit City desig- nation," says Park and Recreation Director Rick Jacobson. "We try to do a great job meeting all of the criteria, and we're continually working to improve." This work includes: maintaining and developing walkable 0 routes, recreation areas, parks, play- grounds, and play fields maintaining and developing indoor facili- ties available for cold season activity that are open and accessible to all ages partnering with community -wide orga-26 - nizations dedicated to activities that support physical activity promoting or sponsoring events or o 0 activities a rIT %-HIES HAVE INVIIINIA PLACES IU WALK. "We hope to help build community through people, parks, and programs," adds Jacobson, "and these are things our resi- dents said were important during the Envision Golden Valley process." The governor declared 2005 "The Year of Fitness" in Minnesota and created the "Governor's Fitness Challenge," which allows citizens to track their fitness progress online at www.6eactiveminnesota.org. More information about the Governor's Fit City program can be found at www.keaItk.state.mn.us/fitcity/.
