The City will be solely responsible for minor and major maintenance, inspection and repair of the Teagarden Detention Basin and the public storm sewer system shown in red on the Stormwater Responsibility Map. The Property Owner is responsible for maintenance of open channels and private pipes shown in pink on the Stormwater Responsibility Map within the development property limits. The City is responsible for maintenance and upkeep of open channels located outside of development limits. The City and the Property Owner shall have joint maintenance responsibilities of North Pond A, North Pond B and North Pond C and the culverts under W. Crystal Street. The Property Owner is responsible for minor maintenance and the City is responsible for inspection and major maintenance. Major maintenance includes: ▬Routinely check water depths for signs of siltation. Remove accumulated sediment when func- tion of basin is impacted by sediment. ▬Replacement of outlet structures. Minor maintenance is all other maintenance that is not defined as major maintenance and includes: ▬Routinely cleanup debris in basins and private pipes. ▬Routinely monitor the permanent pond pool levels for consistency and inspect further when evi- dence suggests higher or lower pool levels. ▬Grass and vegetation mowing. ▬Routinely check for and removal of invasive vegetation including woody vegetation around the perimeter of the basins and within open channels. ▬Monitor for areas where vegetation should replanted. ▬Monitor for invasive species growth and develop a system for eliminating unwanted species. ▬Monitor for nuisance burrowing animals. This includes rodents, groundhog and muskrats. Existing burrows should be plugged by filling with similar material to existing material. Further action may be necessary to make the area unattractive to undesired species. ▬Monitor for nuisance waterfowl. This includes geese and ducks. Maintain a vegetated shoreline higher that 12 inches to discourage waterfowl. Remove and relocate waterfowl. ▬Monitor and removed invasive aquatic vegetation, including algae, duckweed. ▬Removal of clogs. ▬Repairing of inlet pipes. ▬Repairing of revetment to protect from scour. ▬Repairing of embankments and side slopes. ▬Repairing of outlet control structures. Distribution of Maintenance Responsibilities 4 Tree Maintenance Trees also play an important role in the landscape, and proper maintenance of these elements will ensure long-term health and aesthetic appeal for the overall subdivision. Maintenance of trees located on private property is the responsibility of the home owner. The property owner is responsible for tree maintenance within shared public use spaces and the city is responsible for trees within the right-of-way. Regular Maintenance Suggestions: ▬Inspect new plantings often for mechanical or pest damage. ▬Provide adequate water through the first growing season to properly establish new plantings. ▬Prune as necessary in spring and/or fall to remove damaged branches and promote new growth. ▬Fertilize trees annually in September, shrubs in spring and fall. AVOID using nitrogen fertilizers - use complete fertilizers only after a soil test. ▬Compost disease-free material. ▬Check remaining mulch level during the spring and add mulch to maintain the level with no more than 4 inches of material over the roots. ▬Check the root collar by removing soil and mulch to keep it exposed annually for the first three years, then every 4 years after establishment. ▬Place guards on small trees in November to protect from wildlife damamge throughout winter months. ▬Remove heavy snow/ice from limbs to prevent breaking from overloading. 5Wet Pond Maintenance Typical Maintenance Practices for Wet Ponds: Vegetative Cover: The seed mixes specified for the banks of the wet pond were selected because of their adaptability with this environment. This mix also consists of native species to provide a long-term, low maintenance vegetative cover once established. Routine Inspections: An important aspect of any pond inspection is familiarity with the intended design and function. A set of record drawings can often serve as the best resource for evaluating overall performance. The following list provides for expected maintenance needs associated with wet ponds. Try to avoid inspecting within 2 to 3 days after a significant rainstorm to give the facility time to reflect normal conditions. (The exception to this rule is if a problem is expected that may only be apparent at higher ponding levels.) Established Wet Pond, http://dnr.wi.gov/topic/stormwater/images/ 6 Native Plantings Maintenance Established grasses, www.bluestem.ca Establishment Period and Maintenance Practices for Native Plantings First Year: Perennials, wildflowers and grasses grow slowly, and annual and biennial weeds will grow much faster in the first two years. Most native plantings will not grow taller than six inches the first growing season and will seldom be damaged by mowing. Keeping weeds cut back also prevents production of more weed seeds that could cause problems in subsequent years. Mowing weeds on a regular basis is one of the most critical steps in the success of establishment for your native vegetation area. Flail-type mowers work best because they chop weeds up and prevent clippings from smothering small native seedlings. Weed-trimmers are excellent for smaller areas as they drop weeds atop cut stems and allow them to rapidly dry out. Rotary or bar-sickle mowers can be used but can smother seedlings because they do not chop weeds. ▬Weeds should be cut to 6 inches once they reach a height of 12 inches. ▬Control weeds by keeping them mowed back to a height of 6 inches during the first year. ▬Expect to mow weeds about once per month during the first year (this will vary depending on rainfall). ▬Pulling weeds is discouraged, but weeds can be cut at the base when in bloom to discourage spreading. If a cover crop was used to stabilize the site, it should also be cut during the first season. Cutting the cover crop will not harm its effectiveness. Its purpose is to rapidly stabilize soil, prevent erosion, and provide cover for newly-germinated native seedlings. The cover crop will have done its job once weeds reach 12 inches tall and needs to be mowed. ▬Do not mow down the first year’s growth at the end of the season. This will protect young plants over winter and will capture snow to insulate the soil. 7Native Plantings Maintenance Established grasses, wmeanpl.blogspot.com Second Year: Mow the planting down to the ground and rake off cuttings in mid-spring of the second year to prevent weeds from dominating the site. Mowing in the spring stimulates germination of dormant native seeds and promotes growth of native plants having germinated during the first year. If weeds are a problem mow in mid to late June at a height of one foot. Mowing weeds at this height will kill or set back most competitive weeds with minimal damage to native plants. Third Year: Mowing native plantings on a regular basis helps ensure its continued success. Mowing can effectively expose soil to the warming rays of the sun while reducing vegetation litter. ▬Mow down to the soil surface (within 1 inch of the ground) ▬Rake all cuttings to expose soil to the sun ▬Do Not mow after new plant growth has reached one foot or taller to avoid damage to native plantings Though mowing should reduce the appearance of undesirable plants into your native plantings, certain invasive weeds may be evident during the second or third year. These may need to be spot treated with a herbicide, being careful not to damage adjacent native plant material, or through pulling and removing from the site. Native plants will often germinate over a period of two to three years. Most native plants will not begin to flower until their third or fourth growing season. As a result, the native planting area may appear ‘weedy’ in the first year or two. By the third year, the natives should take hold and begin blooming. 8 Dry Detention Basins - Turf Management Typical Maintenance Practices for Dry Detention Basins Dry Detention Basins are designed to detain stormwater runoff from bioretention basins and other adjacent areas of the site and slowly release excess water downstream. Properly functioning basins will allow sediment particles and associated pollutants to settle out prior to draining off the site and entering the storm sewer system. The dry detention basin technique used on this site is intended to be an open lawn area with minimal water depth capacity during heavy rain events. The following maintenance schedule will help ensure that both the aesthetic and functionality of the stormwater system remains effective. First Year: During the first year the greatest challenge is ensuring that proper moisture is available for new grass to establish. Prior to full establishment many of the areas are prone to rill erosion if not properly protected with erosion control mulch or erosion blankets. The following maintenance items are essential to the success of dry detention basin establishment. The developer is responsible for the following items during the first year. ▬All slopes greater than 4:1 need to be protected with properly installed erosion control blanketing. This will prevent additional sediment from side slopes from accumulating in the basin. ▬After grass is seeded, all areas must receive at least one inch of water per week. If planted early in the spring additional watering is usually not required. ▬Allow grass areas to grow undisturbed until a height of 6 inches. After grass areas have achieved this height these areas can be mowed at a medium height (4” average) to reduce weeds from shading desired seedlings and producing seeds. ▬Mowing shall follow the natural contours and general shape of the lawn area in order to allow mowing pattern changes to prevent rutting or soil compaction from wheel tracks. Erosion Control Blanket, Northwood, IATemporary Rolled Erosion Constrol Mat Installation Prepare seed bed prior to blanketing Install beginning of roll in 6”x6” anchor trench. Roll blankets in direction of water flow. Blanket edges overlap 2” min. and stapled. Overlap blanket end by 6” min. with upslope blanket on top 1 5 2 3 4 9Dry Detention Basins - Turf Management Turf Grass Dry Detention Basin, http://www.stormwaterpa.org/ Routine Inspections: A dry detention basin is a self functioning system if all areas of the design are properly managed and cared for. The following are standard maintenance items that must be performed on a regular basis. ▬Inspect side slopes and repair undercut or eroded areas seasonally. ▬Monitor sediment accumulation and remove as needed to prevent damage to plant material and/or the system’s storage capacity. ▬Seed or sod any dead or damaged vegetated areas during the suggested seeding dates (See Appendix). ▬Examine inlet and outlet devices to ensure these structures are free of debris and operational, remove debris and litter as needed. ▬Inspect 1 year extended detention outlet orifice for clogging and remove any debris. ▬Monitor weed growth and use selective herbicide application, as needed - or hand pull or mow agressive weeds to inhibit distribution of weed seeds and encourage desired plants. 10 Established grasses, www.galleryhip.com & welcomewildlife.com Establishment Period and Maintenance Practices for Low Maintenance Turf: Patience and perseverance are often key to establishing a low maintenance lawn. Low maintenance lawn mixes do not germinate in a dense stand like other grasses; but becomes progressively thicker each year. Low maintenance grasses will fail if overmanaged. The following notes apply for low grow seed mix: Established stands require only 1 to 2 pounds of nitrogen per 1,000 square feet per year. Depending on available nutrients in the soil, many lawns may never need to be fertilized. If it appears that a fertilizer could be used to increase nutrients, select a fertilizer with a N-P-K ratio of 3-1-2 or 4-1-2 and at least 35% slow-release nitrogen. Apply fertilizer at a rate of 1 pound of nitrogen per 1,000 square feet in June and again in late July or early August to augment nutrients in the soil. Water low maintenance lawns only enough to maintain growth and prevent dormancy. These species will survive extended drought but will lose color as they go dormant. Be careful not to overwater, as this can increase competition with weeds and may increase incidence of disease. Maintenance of turf will be the responsibility of the homeowner on private property and the property owner on public shared-use property. First Year: During the first and second years, persistent attention to weed control may be required. Keeping weeds cut back provides space for young plants to expand and limits production of weed seed that could cause problems in subsequent years. A regular lawn mower set to its highest setting will generally be sufficient to chop weeds and prevent clippings from smothering desired seedlings. Weed-trimmers are excellent for smaller areas as they drop weeds atop cut stems and allow them to rapidly dry out. ▬If necessary, lawn areas can be mowed to control weed growth that may shade turf. Mowing before weeds seed also inhibits weed seed production. ▬Control weeds by keeping them mowed back, using the highest mower setting. Frequency will vary depending on weed germination and other enivornemental factors such as rainfall. Low Maintenance Turf 11 Established grasses in early spring, build.npnrd.org ▬Hand weeding is discouraged. Weeds can be cut at the base when in bloom to discourage spreading. ▬Do not use products with 2, 4-D on low maintenance turf during the first year of establishment or when temperatures exceed 80 degress Farenheit. If a cover crop was used to stabilize the site, it should also be cut during the first season. Cutting the cover crop will not harm its effectiveness. Its purpose is to rapidly stabilize soil, prevent erosion, and provide cover for newly-germinated native seedlings. ▬Do not mow the first year’s growth at the end of the season. This will protect young plants over winter and will capture snow to insulate the soil. Subsequent Years: Mow low maintenance turf stands to a height of 3 to 4 inches to remove old growth. Delay mowing in the spring until ground temperatures are warmer to stimulate growth of native plants and prevent weed growth germination. If weeds are a problem, mow in mid to late June at the highest mower setting. Mowing weeds at this height will kill or set back most competitive weeds with minimal damage to native plants. ▬Where moderate to high quality turf is desired mow once per week at a height of 2-3 inches ▬Where low maintenance areas are desired mow every 3 to 4 weeks at a height of 3-4 inches ▬Low maintenance turf may also remain unmown except for an annual spring mowing at a height of 3-4 inches to remove old growth ▬Annual weeds may be controlled with a spring application of pre-emergence herbicide labeled for use with low maintenance turf (species comprising). Herbicides should be used sparingly. ▬Broadleaf weeds may be controlled by using any of several herbicides labeled for use with low maintenance turf species. (Fall applications are preferred for control of broadleaf weeds.) ▬Products containing 2, 4-D should be used sparingly as they can cause slight discoloration during spring and summer. Spot treatment applications of these products are most effective during the early spring or fall. Low Maintenance Turf 12 Native Grass Maintenance Establishment Period and Maintenance Practices for Native Plantings The following notes apply to many of the seed mixes employed on the site; including: ▬Native Prairie Seed Mix ▬Conservation Seed Mix First Year: Native grasses grow slowly, and can be smothered out by annual and biennial weeds in the first two years without careful maintenance. Most native plantings will not grow taller than six inches during the first growing season and will seldom be damaged by mowing. Keeping weeds cut back also prevents production of more weed seeds that could compound problems in subsequent years. Mowing weeds on a regular basis is one of the most critical steps in the success of establishing your native vegetation area. Flail-type mowers work best because they chop weeds and prevent clippings from smothering small native seedlings. Weed-trimmers are excellent for smaller areas as they drop weeds atop cut stems and allow them to rapidly dry out. Rotary or bar-sickle mowers can be used but can smother seedlings because they do not chop weeds. ▬Weeds should be cut to 6 inches once they reach a height of 12 inches. ▬Control weeds by keeping them mowed back to a height of 6 inches during the first year. ▬Expect to mow weeds about once per month during the first year (this will vary depending on rainfall). ▬Hand weeding is discouraged.

Cutting the cover crop will not harm its effectiveness. Its purpose is to rapidly stabilize soil, prevent erosion, and provide cover for newly-germinated native seedlings. The cover crop will have done its job once weeds reach 12 inches tall and needs to be mowed. ▬DO NOT mow down the first year’s growth at the end of the season. This will protect young plants over winter and will capture snow to insulate the soil. Established grasses, extras.mnginteractive.com; unitedseeds.com 13Native Grass Maintenance Established prairie grasses, project-eden.org Second Year: Mow native plantings to the ground and rake off cuttings in mid-spring of the second year (before native plants achieve the height of mower blades) to prevent weeds from dominating the site. Mowing in the spring stimulates germination of dormant native seeds and promotes growth of native plants having germinated during the first year. If weeds are a problem, mow in mid to late June at a height of one foot. Mowing weeds at this height will kill or set back most competitive weeds with minimal damage to native plants. Third Year: Mowing native plantings on a regular basis helps ensure their continued success. Mowing can effectively expose soil to the warming rays of the sun while reducing vegetation litter. ▬Mow down to the soil surface (within 1 inch of the ground) ▬Rake and remove all large cuttings to expose soil to the sun ▬DO NOT mow after new plant growth has reached one foot or taller to avoid damage to native plantings Though mowing should reduce the appearance of undesirable plants into your native plantings, certain invasive weeds may be evident during the second or third year. These may need to be spot treated with a herbicide, being careful not to damage adjacent native plant material. These may also be removed through selective pulling, depending on the size of the affected area. 14 Sudas Type 1 (Permanent Lawn Mixture): Contains: 25 lb/acre Creeping Red Fescue 20 lb/acre Turf-type Perennial Ryegrass 1 20 lb/acre Turf-type Perennial Ryegrass 2 65 lb/acre Kentucky Bluegrass Cultivar 1 65 lb/acre Kentucky Bluegrass Cultivar 2 65 lb/acre Kentucky Bluegrass Cultivar 3 Seeding Information: Seed Depth: 1/4” Floodplain Mix: Contains: 3.75 lb/acre Big Bluestem 6.25 lb/acre Virginia Wildrye 2.5 lb/acre Canada Wildrye 7.5 lb/acre Western Wheatgrass 1.25 lb/acre Switchgrass 0.5 lb/acre Fox Sedge 0.75 lb/acre Red Top 2.5 lb/acre Oats/Wheat (Cover Crop) Seeding Information: Seed Depth: 1/4” Little Buckaroo Mix: Contains: 10 lb/acre Seed Oats or Wheat 3 lb/acre Buffalograss 2.6 lb/acre Little Bluestem 2.4 lb/acre Sideoats Grama 1.2 lb/acre Blue Grama 0.8 lb/acre Prairie Dropseed Seeding Information: Seed Depth: 1/4” Appendix I: Seeding & Planting Dates Description: Seed mixes are designed with long-term maintenance practices in mind.

There are a va- riety of wildlife mitigation techniques that will implemented are part of the Brick Towne development. The following are mitigation techniques to be integrated into the site. Trash Open trash containers can be an attraction for wildlife. All trash dumpsters shall be closed and any food shall be thrown away and not left on the ground to attract wildlife. Grass Management The ponds located on the site will be planted with tall grasses surrounding the entire ponds. Tall grasses and steep banks along the edge of a body of water are a deterrent for waterfowl. The grasses chosen will help to provide a thick barrier along the entire edge of the ponds. The steep slopes along the banks will provide an area that is not inviting to birds for nesting purposes. Short grass (2-4 inches) attracts more birds than longer grass (6- 12 inches). In some cases, very long grass (1.5 – 3.0 ft) is necessary to deter the major hazardous species of birds. Predators, including rap- tors and certain terrestrial grassland bird species, do not like to hunt for their prey, particularly small mammals, in long grass. When birds are not hunting, they like to have clear all-round vision to avoid danger. Longer grass creates an insecurity factor and discourages them from landing, resting or nest- ing in this type of grassland habitat. The grasses around the ponds will be in the tall category to deter major hazardous species of birds. The period during which grass is cut is a determining factor in wildlife hazard management. It is essential to be able to carry out this work under dry weather conditions and be sure that it can be completed as rapidly as possible. The period after mowing should allow for grass to grow to its optimal height before the next mowing is carried out. The grass that is cut must be sufficiently mulched, or collected and removed from the development. The presence on the ground of decomposing grass creates a thatch layer that favors an increase in in- vertebrate numbers which will in turn attract birds. Clumps of grass also provide ideal nesting habitat for field rodents and can contribute to high rodent populations which can attract raptors. Canada Geese live in Iowa year round. However, their migration pattern is typically seen between Sept. 30 – January 15, so there isn’t really a great time to cut grass in the fall and not risk inviting them staying; especially with the amount of available grain left over from farming. Nesting occurs in late spring so any cut- ting shall be completed in the early spring. Grass shall be cut to a minimum height of 8”. This will knock down the upper portions while still making it uncomfortable for nesting. 17Wildlife Mitigation Techniques and Monitoring/Response Plan Pond Management The ponds will located on site will be a combination of wet and dry ponds. The slope of the ponds are designed at a 3:1 slope to provide a steep bank and help deter birds from nesting around the edges of the ponds. The slopes along the ponds will require annual inspections to ensure they are in good shape and any signs of erosion are addressed and fixed. The outlet structure for the ponds will be inspected to ensure they are functioning properly and storm water is being managed as designed. Tenant Education The tenants of the development need to be informed of the wildlife mitigation program and can be critical part of the success of the wildlife mitigation program. Tenants will be informed by the property owner that feeding of birds or wildlife is prohibited. They should contact the property management company if they see any nesting wildlife. Wildlife hazard management is not an exact science and different species of wildlife respond differ- ently to changing circumstances. It is critical that the wildlife mitigation techniques in place are flex- ible and able to integrate new research and principles as they become available. The results of new research or finding need to be able to be applied to the operational and management techniques for the development. Monitoring/Response Plan The owner shall implement a monitoring and response plan for the storm water management features on the site. The monitoring shall be completed quarterly. The monitoring/response plan shall be kept on site. Form A1 shall be used to track the monitoring of the Wildlife mitigation techniques and is attached. All inspections shall be done by a licensed professional engineer or landscape architect or a certified professional in erosion and sediment control, credentialed in a manner acceptable to the City. If any wildlife nests are found during an inspection the USDA Wildlife services or the Iowa DNR conservation division shall be contacted to help relocated or remove any nests found. 18 Wildlife Mitigation Techniques and Monitoring/Response Plan A.1 – Wildlife Mitigation Monitoring and Response Plan Inspection Log Site: Brick Towne Development  Quarterly Report  Event Based (Describe Event) Event Description: ___________________________________________________________________ _____________________________________________________________________________________ Measures Observed: Condition: Remarks:  Trash Enclosures  Good  Corrective Action Req’d __________________  Grass Height  Good  Corrective Action Req’d __________________  Grass Thickness  Good  Corrective Action Req’d __________________  Grass Clippings  Good  Corrective Action Req’d __________________  Pond Slopes  Good  Corrective Action Req’d __________________  Outlet Structures  Good  Corrective Action Req’d __________________  General Erosion  Good  Corrective Action Req’d __________________  Birds Nests  Good  Corrective Action Req’d __________________  Other________________  Good  Corrective Action Req’d __________________  Other________________  Good  Corrective Action Req’d __________________  Other________________  Good  Corrective Action Req’d __________________ Corrective Actions Taken: __________________________________________________________________________ ____________________________________________________________________________________________________ ____________________________________________________________________________________________________ ____________________________________________________________________________________________________ ______________________________________________ Name: ____________________________________________ Title: ____________________________________________ Date: ____________________________________________ Address: _________________________________________ Telephone: ________________________________________
