It was noted that both the base rate and usage rate have increased, coupled with the drought-like summer increasing usage all contributed to increase water bills. He also inquired about the gas station bid opening. Mr. Wuerth stated bid information will be available next week. Aubrey requested an update on the WWTP management transition. Mr. Wuerth stated it is stable through the current construction, and that is an ongoing evolution. ADJOURN The meeting was adjourned at 7:45 p.m. P.J.

We were considering fixing the existing vehicle to use for ordinance. As we looked into this further we found it not to be cost effective. ACTION REQUESTED To sell a 2006 GMC Sierra 4x2 via online auction. 6 6 7 moTrai \\i Pace Ileallifient Thomas Lindberg —Chief of Police INTER-OFFICE MEMO TO: Thomas C. Lindberg, Chief of Police FROM: Kevin Knauss, Sergeant DATE: 09/08/2016 SUBJECT: Active Shooter Vest with Protective Armor Plates - Proposal This proposal is a formal request to allocate funds from the forfeiture account to purchase "Active Shooter" vests and protective armor plates for each of our MCOLES certified officers. These vests are vital for the protection of officers from high powered rifle rounds if responding to an active killer incident or other "high risk" deployment. This proposal includes the recommendation to purchase (20) Lightweight Critical Mission Response Rig vests from Officer Safety Solutions in Carlsbad, California. As a current member of the Oakland County Tactical Consortium (OakTac), the Milford Police Department continues to provide annual Active Shooter Response Training to its officers. As a result, officers are equipped with the tactical skills to effectively respond to an "active killing" event. This training has also identified that the overwhelming majority of "active killers" employ rifles, LED's (improvised explosive devices) and personal body armor during their attacks. In short, these actors are well armed and anticipate a law enforcement response when conducting their attacks. Although Milford officers are provided bullet resistant vests as part of their daily uniform, this equipment is not designed to offer protection against rifle rounds or explosive devices. Without the enhanced protection offered by supplemental armored vests, officers responding to an active killing incident are at a marked disadvantage to those they are charged to stop. After researching several armor packages, I would recommend the Lightweight Critical Mission Response Rig offered by Officer Safety Solutions, of Carlsbad, California. This package includes (1) quick release plate carrier;(2) NIJ 0101.06 Ultra Lightweight Level III Stand Alone , Multi-flit " Certified " Polyethylene Armor Plates; (1) triple rifle magazine pouch; (1) triple pistol magazine pouch; (1) OSS Trauma plate pack; and (2) "POLICE" ID panels for the price of $699 per unit. The Level III plates provide ballistic protection from the most popular modern rifle ammunition and represent the latest technology in the industry. The Milford Police Department is seeking a total disbursement of $14,438.50 (shipping charge included) from the department's Forfeiture Account for aforementioned equipment. Please do not hesitate to contact me with any questions related to this matter. Sgt Kevin nauss 7 1e32 IL FORS L FO TO: Village Council FROM: Christian Wuerth, Village Manager DATE: September 14, 2016 SUBJECT: Additional Electric Service for Central Park Restrooms In preparing for the installation of electrical service to the new restroom building in Central Park, it was determined that a new transformer and panel, along with associated items, would need to be installed to meet code requirements. As these items were not originally anticipated, quotes were obtained from several local contractors, with the lowest quote being from Landry Electric, who is the current electrical contractor for the project. In order to complete this work, approval is needed for an additional $5,900, to cover the additional labor and materials. SUGGESTED RESOLUTION To approve the additional electrical materials and labor for the Central Park Restroom project, in an amount not to exceed $5,900 from Landry Electric. 8 Landry Electric PO box 1625 Brighton, Mi. 48116 Date Estimate # 8/23/2016 13-386 9 Estimate Name / Address John Stewart Assoc. 1645 North Milford Rd.

Existing practice has been for the new rates to become effective for all invoices generated on or after the July 1 start of the fiscal year. As best we can determine based upon a review of the files, this practice dates to the 1970s, and likely earlier. At the August 15, 2016 meeting Council discussed possible changes to this policy and requested additional information from staff. In reviewing the information related to this issue, the core issue is billing the effective rate based upon the actual date of usage - which our current system does not allow. There are two potential solutions to this issue - upgrading the meter reading infrastructure or adopting a new policy to prorate the billing periods which overlap two different rate structures. The majority of water meters currently in use within the Village require manual reading, and each of the three billing sections take approximately 2 weeks to read and process. While these meters are not yet obsolete, they are several generations behind the latest technologies and a vast majority of the meters require Village staff to physically connect to the meter infrastructure to obtain a read. Newer meter systems range from technologies that would simply require staff to drive by the meter to technologies which would allow for remote meter reading from a central point. Either technology could help to resolve the issue at hand, but both come at a cost - in excess of $1 million - in order to fully deploy within the system. In speaking with our current meter provider, the meters with the "drive-by" technology are fairly easily upgraded at a later date, if the Village opts to pursue a fixed read system. At this time, the Village already requires new water meter installations and replacements to utilize the meters with the "drive-by" reading technology, which will ultimately allow for a shorter timeframe for staff to read meters - freeing them up for additional tasks. These meters are able to be retrofitted in the event the Village decides to pursue a fixed read system in the future. It may also be feasible to replace the reading equipment on existing meters at a lower cost than a full replacement program. In speaking with our software provider (BS&A), they can assist the Village in implementing a mechanism to prorate future water bills. This would allow for the bills to be broken into periods covering two different rate structures. Though this is not 100% accurate, it is reasonable, and outside an initial learning curve, fairly easily implemented. After reviewing the available options, this is the most cost-effective method of correcting the existing policy. I would request that Council provide formal action on establishing a new policy of prorating water and sewer bills for the first billing cycle following the effective date of new utility rates. 15 16 It is my recommendation that this policy change be made effective with the 2017-2018 Fiscal Year Budget, as the current budget was adopted based upon the existing policy. A retroactive change would require water and sewer rates to be adjusted upward in order to maintain a balanced FY2016-2017 Budget, as detailed in the attached memorandum for Treasurer/Finance Director Penny Ray. This is based upon the fact that the water and sewer rates are calculated based upon necessary operations, maintenance, and capital expenses for the fiscal year and the projected usage. Another issue that arose during the prior discussion was whether or not the actual read dates could be printed on future water/sewer bills. This change is easily made and will be implemented once we are satisfied that the format is easily read by customers - no Council action is required. SUGGESTED RESOLUTION To adopt a policy directing that water and sewer utility bills be prorated for the first billing cycle following the effective date of new utility rates, effective with the Fiscal Year 2017-2018 Budget. 16 VILLAGE OF MILFORD 17 1100 ATLANTIC STREET MILFORD, MICHIGAN 48381 MEMORANDUM TO: Christian Wuerth, Village Manager FROM: Penny Ray, Treasurer/Finance Director DATE: September 2, 2016 RE: 2016-2017 Water/Wastewater Rates In regards to the conversation regarding how we bill for water and sewer rate increases some alternatives have been explored. One of the options was to prorate the bills and credit back the difference between the old and new rates. The problem with this is that the rates for 16-17 have been set based on the needs of the system so revenues need to be raised to meet those needs. Rates are simply calculated by taking the cost of operating the water/sewer system and dividing that number by the estimated number of gallons sold, the result is the cost per 1,000 gallons. I have calculated what it would take to make up the difference if we were to credit back the difference in the rates, the amounts vary based on the revenue needed. Revised Rates: Current Rates: Water Use 1.88 Water Use 1.91 Water Bond 2.40 Water Bond 2.42 Sewer Use 6.31 Sewer Use 6.41 *Sewer Bond 0.22 *Sewer Bond 0.22 By adjusting the rates we ensure that there is enough revenue to maintain a balanced budget. *Sewer bond does not increase since the rate is the same as last year. 17 VILLAGE OF MILFORD ORDINANCE NO. 231-203 ENGINEERING DESIGN AND CONSTRUCTION STANDARDS AMENDMENT AN ORDINANCE TO AMEND ARTICLE I, IN GENERAL, THROUGH ARTICLE XIII, AS-BUILT DRAWINGS, PROCEDURES AND REQUIREMENTS, OF CHAPTER 38, ENGINEERING DESIGN AND CONSTRUCTION STANDARDS, OF THE CODE OF ORDINANCES FOR THE VILLAGE OF MILFORD, IN ORDER TO ADOPT THE VILLAGE OF MILFORD ENGINEERING STANDARDS AND DESIGN SPECIFICATIONS, AS AMENDED, AS THE MINIMUM ENGINEERING REQUIREMENTS FOR THE DESIGN AND CONSTRUCTION OF SUBDIVISIONS, SITE PLAN IMPROVEMENTS, UTILITY SYSTEMS AND ROADS LOCATED WITHIN THE VILLAGE.

Voids outside the pipe barrel, placed in the pipe opening, shall be sealed with an approved nonshrinking grout. A concrete collar shall then be poured 12 inches thick around the pipe and extended a minimum 12 inches beyond the outside wall surface of the manhole with the remainder of the pipe cradled in concrete. (2) Inclusion with sewer construction. Unless otherwise approved, construction of house leads from the public sewer to the easement and/or property line for each fronting parcel which the sewer is designed to serve shall be included with the construction of each sanitary sewer.

The bell and spigot surfaces shall be wiped clean. The surfaces (bell, spigot, synthetic rubber 0-ring gasket) shall then be coated with a lubricating material to overcome the friction resistance when setting the precast sections home. d. Manhole structures which are to be left open overnight shall be securely enclosed with suitable fencing and have adequate lighted barricades. e. All manholes shall be supported on a firm, stable foundation. The foundation shall remain stable during backfilling and subsequent operations. (3) Drop manholes. A drop manhole shall be constructed whenever an inlet sewer pipe enters a manhole at an invert elevation 18 inches or more above the invert elevation of the outlet sewer pipe. Drops between 6 inches and 18 inches will not be permitted. (4) Stubs. Where future connections to a manhole are anticipated, stubs or blind drop connections with watertight plugs shall be provided. (5) Bulkheads. Where sanitary sewers tap into existing manholes, a six-inch masonry bulkhead shall be constructed in the sewer to prevent flow into the existing system from the new system. (6) Materials and appurtenances. All materials contained in these specifications shall conform to the requirements of section 5.14.02, MDOT Standards for Construction, and Oakland County Department of Public Works Standards and Specifications for Sanitary Sewer Construction, except as otherwise specified by the village. (i) Special structures and appurtenances. (1) Preliminary plans. Preliminary plans for special structures and appurtenances required for sanitary sewer systems shall be submitted to the village for review and comment prior to their inclusion in the construction drawings. (2) Inverted siphons.

Adjustments to manhole castings shall be accomplished prior to final acceptance by using precast concrete adjustment rings bolted to the cone section of the manhole with synthetic rubber 0-ring gaskets compressed between each adjacent ring or injection molded high density polyethylene adjustment rings. Sec. 38-157 Acceptance test. All sanitary sewer systems shall be subjected to and must successfully pass a preliminary infiltration, air or exfiltration test, or a combination thereof, in accordance with the requirements of this section prior to scheduling a final acceptance test of the system by the department of public services or village engineer. Removal of the bulkhead as required in section 38-154(h)(5) shall not proceed without approval of the department of public services or village engineer. All final acceptance tests shall be witnessed by the department of public services or the village engineer. (1) Infiltration test. a. All sewers over 24 inches in diameter and all smaller sewers where the groundwater level is more than seven feet above the top of the sewer shall be subjected to an infiltration test. b. Maximum allowable infiltration shall not exceed 200 gallons per inch of diameter per mile of pipe per 24 hours for the overall project. All sewers being tested by the infiltration method shall be allowed to stabilize for a period of 24 hours with the test bulkhead in place. (2) Exfrltr•ation test or air test. All sewers of 24 inches in diameter or less where the groundwater level is seven feet or less above the top of the sewer shall be subjected to either exfiltration tests or air tests as determined by the village engineer. a. Exfiltration test 1. For the purpose of exfiltration testing, the internal water level shall be equal to the external water level plus four feet as measured from the top of the highest pipe in the system being tested. This could be either a house lead or a lateral. However, the maximum total height of water above the invert of the pipe at the lower end shall not exceed 16 feet. A prospective test that would exceed this 16-foot limit should not be taken. The line under construction can be broken down into smaller sections so that the maximum head of 16 feet will not be exceeded. Engineering Design and Construction Standards 27 44 45 2. The actual exfiltration of leakage from the sewer line can be measured by recording the volume of water lost over a given period of time in a standpipe or pipes connected in the upstream and/or downstream manhole, or the upstream manhole can be used provided the test water level is below the bottom on the tapered section. It may be necessary to add a measured amount of water during the testing time interval to maintain water in the standpipe at the specified level so that the total volume of water lost would be based upon the amount of water added and the difference in elevation of water at the end of the testing converted to gallons. When the standpipe method is used, the time interval to record the difference in elevation of the water surface shall be a minimum of 15 minutes. When the upstream manhole method is used, the time interval shall be a minimum of two hours. 3. A minimum of four hours should elapse after the test section is filled with water to permit the escape of trapped air and to allow for maximum absorption. After such absorption and escape of air has taken place, water should be added to the specified test level, and the test begun. 4. The maximum exfiltration rate shall be 200 gallons per inch diameter of pipe per mile of pipe per 24 hours. b. Air test. The procedure for air testing of sewers shall be as follows: 1. The sewer line shall be tested in increments between manholes. The line shall be cleaned and plugged at each manhole. Such plugs shall be designed to hold against the test pressure and shall provide an airtight seal. One of the plugs shall have an orifice through which air can be introduced into the sewer. 2. An air supply line shall be connected to the orifice. The air supply line shall be fitted with suitable control valves and a pressure gauge for continually measuring the air pressure in the sewer. The pressure gauge shall have a minimum diameter of 3.5 inches and a range of zero to ten pounds per square inch gauge. The gauge shall have minimum divisions of one-tenth pound per square inch gauge and an accuracy of plus or minus 0.04 pound per square inch gauge. 3. The sewer shall be pressurized for four pounds per square inch gauge greater than the greatest back pressure caused by groundwater over the top of the sewer pipe. At least two minutes shall be allowed for the air pressure to stabilize between 3.5 and four pounds per square inch gauge. If necessary, air shall be added to the sewer to maintain a pressure of 3.5 pounds per square inch gauge or greater. 4. After the stabilization period, the air supply control valve shall be closed so that no more air will enter the sewer. The sewer air pressure shall be noted and timing for the test begun. The test shall not begin if the air pressure is less than 3.5 pounds per square inch gauge, or such other pressure as is necessary to compensate for groundwater level. 5. The time required for the air pressure to decrease one pound per square inch gauge during the test shall not be less than the time shown in air test tables as developed by the NCPI. 6. Manholes on sewers to be subjected to air tests shall be provided with a one-half-inch diameter galvanized, capped test pipe installed through the manhole wall and extending three inches into the manhole at an elevation equal to the top of the sewer pipe. Prior to the air test, the groundwater elevation shall be determined as follows: Engineering Design and Construction Standards 28 45 46 i. The test pipe in the downstream manhole shall be cleared by blowing air through it. ii. A length of clear plastic tubing shall then be attached to the end of the test pipe and extended vertically upward to or near the top of the manhole. iii. Groundwater will enter and rise in the tubing to the elevation of the groundwater level at the manhole and will be readily visible. The air test pressure shall be adjusted (one foot water equal to 0.433 psi) to compensate for the maximum groundwater level above the top of the sewer pipe to be tested. After all tests are performed and the sewer is ready for final acceptance, the test pipe shall be plugged in an acceptable manner. (3) Test results. a. If a sewer fails to pass any of the previously described tests, the contractor shall determine the location of the leaks, repair them, and retest the sewer. The tests shall be repeated until satisfactory results are obtained. Repair procedures must be approved and inspected by the village engineer. b. All visible leaks and cracks shall be repaired regardless of test results. (4) Safety precautions. The air test can be hazardous under certain conditions. It is extremely important that all air plugs be properly secured and that care be exercised during the test and in the removal of plugs. A 15-inch plug with 4.5 pounds per square inch applied to it exerts almost 800 pounds of force. This is an example of the potential hazard that exists if plugs are not correctly relieved of air pressure before being removed. As a safety precaution, it is suggested that pressurizing equipment be provided with a ten psi pressure relief device to reduce hazards and to avoid over- pressurization and damaging of any sewer lines. No person shall be allowed in manholes during air testing. (5) Televised inspection. All sanitary sewer inspections shall be televised with test results approved by the village engineer prior to placing the sewer in service. (6) Force main testing. a. No sanitary sewer pumping system shall be put into service until all pressure piping (force main) has undergone a satisfactory hydrostatic pressure test witnessed by the village engineer. b. Before applying the specified test pressure, all air shall be expelled from the pipe. The contractor shall furnish proper appliances and facilities for testing and draining the main without injury to the work and surrounding territory. c. The contractor shall be responsible for furnishing, and for the cost of, all water required for pressure testing. He shall test by filling the main with clean water under a minimum hydrostatic pressure of 100 pounds per square inch. In no case shall the leakage in any stretch of pipe being tested exceed the 11 U.S. gallons per inch diameter of main per mile of pipe (0.0001736 multiplied by diameter (inches) multiplied by pipe length (feet) in a two-hour period. d. The contractor shall pressure test sections of force main as directed by the village engineer. Pressure testing shall be made in increments of 2,000 feet or less unless otherwise authorized by the village engineer, and then only the allowable leakage for 2,000 feet will be permitted. (7) Test observations. All final acceptance tests shall be witnessed by representatives of the village engineer or the department of public services.

Section 38-212, Required, Section 38-213, Detention facilities, Section 38-214, Retention facilities, of Article VII, Stormwater Holding Facilities, of Chapter 38, Engineering Design and Construction Standards, of the Code of Ordinances for the Village of Milford, shall be amended to read as follows: Sec. 38-212 Required. All new and redevelopment projects shall provide an on-site stormwater holding facility in accordance with the village stormwater management plan and/or the Oakland County Water Resources Commissioner's (WRC) Standards, or a temporary stormwater holding facility when dictated by downstream capacity. Sec. 38-213 Detention facilities. (a) All detention facilities shall also include the following: (1) A sediment forebay, or equivalent structure, designed to capture the runoff from a one year storm is required for all sites. The forebay should be a separate cell from the main detention basin and designed such that it will dewater within 48 hours. Engineering Design and Construction Standards 36 53 54 The volume of detention within the forebay, above any proposed permanent pool of water, can be considered when calculating total detention volume required for a site. (2) A manufactured storm water treatment system may be used in lieu of a sediment forebay. (3) Green infrastructure or low impact development techniques may be used in lieu of a sediment forebay. (b) Allowable discharge rate. For new development where on-site detention is required, the outflow to an existing drainage course shall be determined according to the current Oakland County Water Resource Commission standards. The village and the county encourage the use of Best Management Practices (BMPs), such as those listed in the SEMCOG Low Impact Design Manual for Michigan (LID Manual), as revised, to help pretreat and infiltrate stmmwater and aid in achieving the calculated allowable discharge rate. (c) Types of detention facilities. The following types of detention facilities will be permitted in the village: (1) Basin detention (pond is permitted upon recommendation by the village engineer); (2) Parking lot detention; (3) Rooftop detention; (4) Other methods of stotmwater detention may be considered under special circumstances. (d) Basin detention. (1) All detention ponds must be capable of complete dewatering by gravity. Only under special circumstances will a pump discharge be allowed to dewater a detention facility and then only upon approval by the village engineer with the knowledge and approval of the village manager. (2) Detention volume is defined as the volume of detention provided above the invert of the lowest outflow pipe. Detention volume must be provided for all on-site acreage. Off-site acreage originally draining across the proposed development will be allowed to pass unrestricted, but must either be intercepted and routed through the project's storm drainage system or otherwise be handled in a manner satisfactory to the village engineer and village attorney. (3) All detention basins must have a provision for overflow set at the high water level capable of passing a 100-year storm. A spillway is an acceptable overflow provision with an outlet located so as not to cause potential hardships to adjacent property. If possible any spillway overflow must flow into a recognized natural drainage course. All spillways shall have a hard surface consisting of concrete, asphalt or grouted riprap, unless otherwise approved by the village engineer. (4) Minimum bottom of basin slopes shall be one percent. This requirement may be waived if another alternative to complete dewatering of the basin is presented and approved by the village engineer. (5) One foot of freeboard shall be provided above the design high water elevations. (6) Maximum side slopes shall be one vertical to four horizontal. Anything greater shall require approval of the village engineer and shall be fenced. Engineering Design and Construction Standards 37 54 55 (7) The volume of stormwater detention shall be computed by the Oakland County Water Resources Commissioner's design procedure for a one hundred-year frequency storm. (8) If interconnected multiple basins are involved in the overall storm system, including both on-site and off-site basins, a detailed hydraulic analysis of the basins must be reviewed and approved by the village engineer. (e) Parking lot detention. (1) Parking lot detention of stormwater will be permitted provided it does not adversely affect the functioning of the facility or business which it serves or create a public nuisance. (2) The required storage volume shall be determined in the same manner as it is done for basin detention. (3) The discharge from the parking lot may be controlled by means of restricted inlets. (4) Where applicable, storage depths of up to nine inches will be permitted in parking areas. (5) Overflow route shall be provided with at least four-tenths of one foot freeboard provided. (0 A forebay must be installed at all incoming discharge points to the basin. The purpose of the forebay is to capture sediment in one area and prevent sediment buildup in the main basin. The forebay shall be a separate basin, which can be formed within the main basin by creating a separation with an earthen berm, gabion wall, riprap berm or rock or concrete retaining wall. A manufactured storm water treatment system or green infrastructure techniques may be used in lieu of a sediment forebay. (1) The sediment forebay shall be sized to accommodate a one-year storm event. The village shall use the method of design presented in the Oakland County Water Resources Commissioner's Engineering Design Standards to verify the forebay design calculations (2) The forebay may be included as part of the total required basin volume, above any permanent pool of water. The forebay cannot be included as available storage if it remains full of water. (3) The side slopes cannot exceed one foot vertical to four feet horizontal. (4) The forebay should have a sump a minimum of two feet deep to capture sediment and prevent resuspension of sediment. The bottom of the basin should slope toward the sump area to capture the sediment. (5) The outlet shall be designed to capture the one-year storm event and dewater the basin within 48 hours. An outlet structure with restricted discharge may also be used within the separation. (6) An outlet (overflow) spillway should be constructed on the separation which allows water to exit the forebay at non-erosive velocities. (7) An access road should be provided for forebay maintenance. An access road is required for all facilities that will be established as a chapter 18, county drain. (8) The forebay should also have a fixed sediment depth marker to measure the amount of sediment that has accumulated. The sediment should be removed when half of the sediment storage capacity has filled in. Engineering Design and Construction Standards 38 55 56 (g) Manufactured storm water treatment systems. Manufactured storm water treatment systems may be used in lieu of a sediment forebay. These devices are used to remove sediment and other particulate matter from storm water runoff. Stormceptor and Vortechs are two brand name devices for such purposes. The Oakland County Water Resources Commissioner does not specify either of the brand name devices be used for a project, unless the project will be ultimately operated and maintained by this office. Other similar devices may be substituted providing that proper supporting data is submitted to this office for review. The supporting data must indicate that the system meets the removal standards referenced herein. (1) Manufactured treatment systems must be installed upstream of the storm water detention system. If the site is not required to provide storm water detention, a manufactured treatment system must be installed upstream of the connection to the ultimate outlet location. (2) The system must treat up to the peak flow rate for the ten-year storm event. (3) The system must remove a minimum of 80 percent of the total suspended solids (TSS), based on a 75-micron particle size. (4) The system must remove 90 percent of the floatable free oil. (h) Innovative BMP's non-traditional storm drainage facilities that improve the quality and reduce the quantity of storm water runoff are encouraged as long as the required detention volume and allowable outflow are achieved. Complete details and specifications for the proposed storm drainage facilities must be submitted. There should be sufficient information provided such that a comprehensive review can be performed. Each case will be evaluated on a site-specific basis. These innovative BMPs may include, but are not limited to, those low-impact development techniques outlined in the Low Impact Development Manual for Michigan. Sec. 38-214 Retention facilities. (a) Retention ponds which are not to be used for aesthetic, agricultural or consumptive reasons but serve the sole purpose of collecting storm runoff will be permitted only if no drains or natural drainage course for discharging of a detention pond are reasonably available to the developer. Such use of retention ponds shall be considered a temporary measure or last resort to be discontinued as soon as a drain becomes available to the development. (b) Retention pond sizing shall be based on soil conditions and shall be sized to accommodate back-to-back 100-year storm volumes. (c) Retention basin volume shall not include volume below the average or existing groundwater table. A comprehensive soil investigation including determination of groundwater levels shall be furnished for all retention basins. (d) All requirements governing detention ponds, unless specifically revised or waived by the village engineer, shall be applicable to retention ponds. (e) Maximum side slopes of retention ponds shall be one vertical to four horizontal. Anything greater shall require approval of the village engineer and shall be fenced.
