BEASLEY, Presiding Judge.
Doyster Tyler and his wife brought this action against Steve Lincoln and Lincoln Realty, who are the developers of a subdivision adjacent to plaintiffs' property, and others. Plaintiffs complain that development of the subdivision has caused excessive storm-water and sediment to be discharged onto their land and into their ponds. Plaintiffs appeal the trial court's grant of summary judgment to the developers.
Between 1975 and 1987, the Tylers assembled an 11.8 acre tract of land in Lowndes County. When they acquired the property, there was a cypress pond in the rear immediately adjacent to a Norfolk Southern railroad track. Toward the front, plaintiffs located their residence and built two additional ponds, one used for fishing. A drainage ditch connects these two ponds with the cypress pond.
In 1992, the developers began constructing Sweetwater Subdivision on land lying on the other side of the railroad track. There is a natural flow of water from the subdivision onto plaintiffs' property, and it is managed by a 24-inch culvert which drains from underneath the railroad track into the cypress pond. In 1994, plaintiffs began complaining to the county of excess stormwater and sediment discharge from the subdivision. The countywhich had approved the subdivision's erosion, sedimentation, and stormwater (i.e., drainage) planrefused to take any action unless plaintiffs submitted documentation of their claim prepared by a registered engineer, but none was provided.
In 1995, Norfolk Southern wrote to the Lowndes County Engineer that the calculation of pre-development and post-development runoff coefficients in the plans for the subdivision indicated a 41 percent increase in post-development stormwater runoff onto adjacent property. Norfolk asserted that the existing culvert was an inadequate containment device, contended that the increased runoff would damage its railroad and plaintiffs' property, and suggested that the county require the developers to construct a detention pond within the subdivision.
Tyler deposed that heavy rains deluge his property with excessive stormwater runoff from the subdivision, which has resulted in the deposit of an undetermined amount of sediment onto plaintiffs' land and into their ponds. According to Tyler's affidavit, his ponds were clear prior to development of the subdivision; they are now so polluted they cannot be used for recreational or aesthetic purposes; flooding depicted in photographs of record resulted from excessive stormwater runoff from the subdivision; and he has repeatedly asked the subdivision developers to correct the problems to no avail. At the time of his deposition he had not attempted to calculate his damages.
Plaintiffs' expert Freshley affirmed that some sedimentation had been discharged from the subdivision into plaintiffs' cypress pond, which he attributed to inadequate soil erosion control measures within the subdivision, and that more water is now being discharged into plaintiffs' ponds than before the subdivision was developed. He offered no opinion as to damages. Plaintiffs submitted photographs from which a jury could find inadequate erosion and/or sediment control measures in the subdivision, flooding of plaintiffs' property, and excessive turbidity and discoloration in their ponds.
Lowndes County Soil Erosion Control Specialist Miller determined, from inspections of plaintiffs' property and NTU (nephelometric turbidity unit) readings, that there has been a very minimal amount of sediment deposits from the subdivision onto plaintiffs' property and none in their ponds. After receiving complaints from plaintiffs, a committee from the Georgia Soil & Water Conservation Commission inspected the site and found that although erosion and sediment control structures *8 in the subdivision were inadequately maintained in certain areas and absent in others, there was no sedimentation on plaintiffs' property and therefore no significant sediment damage.
Tyler testified that algae has formed in plaintiffs' front ponds making fishing impossible but presented no evidence this was attributable to increased water runoff or subdivision sediment. During an investigation into a fish kill in one of plaintiffs' ponds, state environmental personnel found no evidence that contaminated water was being discharged onto plaintiffs' property, that subdivision sediments detrimentally impacted the property, or that the subdivision was impacting the two ponds.
DeVane, the engineer who designed the drainage plans for the subdivision, acknowledged that the 41 percent increase in the runoff coefficients which he had calculated would increase the total volume of surface water runoff, but he had concluded that wetlands within the boundaries of the subdivision would adequately contain the additional runoff.
A Lowndes County ordinance prohibits a drainage system from effecting a net increase of water flow onto adjacent land unless the owner agrees to the proposed drainage design, and all drainage systems discharging water into a creek, stream, or natural body of water including wetlands must pass through an approved sedimentation or detention pond prior to discharge. Because DeVane determined that there would be no net increase of water onto adjacent property, the subdivision developers did not obtain plaintiffs' agreement to the drainage system.
1. The court erred in granting summary judgment to the developers on the plaintiffs' nuisance, trespass, and negligence counts.
The developers sought summary judgment on these counts on grounds that they fully complied with all county ordinances and legal requirements and because all of the government agencies investigating this matter found there has not been any increase in the discharge of water or sediment onto plaintiffs' property or damage thereto. But it would appear that the county ordinance was violated by reason of the developers' failure to construct a sedimentation or detention pond to control the flow of surface water from their subdivision into both wetlands on their property and a cypress pond on adjacent property.
There are also unresolved issues concerning whether the developers are currently in violation of Georgia's Erosion & Sedimentation Act.[1] For all land-disturbing activities, this act requires best management practices which include proper installation and maintenance of facilities to control sediment and stormwater runoff and soil erosion.[2] Violations of the county ordinance and state statute would constitute negligence per se.[3] And the testimony of Tyler and his expert, the letter from the railroad, and photographs in the record would authorize a jury to find that development of the subdivision has increased the flow of surface water and sediment onto plaintiffs' property.[4] Such evidence would support findings of trespass and nuisance.[5]
As to damages,
[a] failure on the part of [plaintiffs] to produce any probative evidence as to the specific amount of damage they may have suffered is not a viable basis for the grant of summary judgment against them. "The law infers some damage from the invasion of a property right; and if no evidence is *9 given of any particular amount of loss, it declares the right by awarding what it terms `nominal damages.' (Cits.)" [Cit.][6]
The measure or quantification of personal damages recoverable in a nuisance case is the enlightened conscience of the jury.[7] Actual damages as such, i.e., injuries, are evidenced by a showing that property owners are deprived of the full use and enjoyment of their property by the increased flow of surface waters or sediment on it.[8]
2. The court did not err in granting summary judgment to developers on the count of plaintiffs' complaint alleging violation of their riparian rights.
Riparian rights are defined as the rights of the owners of lands on the banks of watercourses.[9] Georgia statutes refer to watercourses as "running waters."[10] Although plaintiffs correctly state that a swale or depression over which surface water runs according to the laws of nature is a watercourse even if it has no defined banks,[11] surface water runs from the subdivision onto plaintiffs' property by means of a man-made structure, i.e., a culvert. The doctrine of riparian rights is simply inapplicable.
3. Neither did the court err in granting summary judgment to the developers as to plaintiffs' claims for punitive damages under OCGA § 51-12-5.1(b) and attorney fees under OCGA § 13-6-11.
Plaintiffs base these claims on assertions that in creating the drainage system for the subdivision, the developers wilfully or intentionally diverted water onto plaintiffs' property and/or failed to correct the resultant problems when brought to their attention. Plaintiffs maintain that the developers are thereby chargeable with "bad faith," so as to authorize a recovery of attorney fees under OCGA § 13-6-11, and with "that entire want of care which would raise the presumption of conscious indifference to consequences," so as to warrant punitive damages under OCGA § 51-12-5.1(b).
There is no evidence of any complaints to the developers while the subdivision was being built or that the drainage system was designed with knowledge that it would increase the runoff of storm-water or sediment onto plaintiffs' property. Because of this, and given the developers' compliance with all requirements imposed by the county,[12] plaintiffs' failure to comply with the county's request that they provide documentation of their complaints,[13] and the uniform findings of the various governmental agencies as to plaintiffs' lack of damages, the developers are not chargeable with either bad faith or a conscious indifference to consequences in designing or failing to maintain or repair the subdivision's drainage system.[14]
